Résumé :

Background: Rugby union is a popular and continuously growing sport globally. With the advance of technology, practices have been implemented to quantify the match running demands of rugby union players. The aim of this study was to analyse the match loads of rugby union players between the 2016 and 2018 Varsity Cup competitions. Methods: The sample consisted of 562 match observations of male university rugby union players competing in the Varsity Cup tournaments. Results: The backline players ran significantly longer total distances (5105 m; p = 0.001; ES = 0.49); have greater high- speed running (496 m; p = 0.001; ES = 1.03), very high-speed running (260 m; p = 0.001; ES = 1.50) and sprint distances (117 m; p = 0.001; ES = 1.32) than forward players. Backline players also accumulated a high number of metres per minute (238 ± 94; p = 0.001; ES = 0.46), total Player Load (488 ± 203; p = 0.001; ES = 0.31), RHIE (9 ± 8; p = 0.001; ES = 0.75) and number of accelerations (4 ± 5; p = 0.001; ES = 0.49). Conclusion: These findings may assist coaches to develop player position specific training programmes to meet the physical demands of rugby. Keywords: rugby union, match loads, physical demands, position

Résumé :

Purpose:To compare critical speed (CS) derived from all-out testing (AOT) for linear and shuttle running with metrics from a graded exercise test, the Yo-Yo Intermittent Recovery Test Level 1 (YYIR1), and estimation of an 800-m-shuttle time trial.Methods:Twelve male rugby players completed a graded exercise test, the YYIR1, a linear AOT, shuttle AOTs of 25 and 50 m, and an 800-m-shuttle time trial consisting of 32 × 25-m shuttles.Results:Strong linear correlations were observed between maximum oxygen uptake () and CS (m·s−1) derived from the linear AOT (3.68 [0.62],r = .90,P < .01) and 50-m-shuttle AOT (3.19 [0.26],r = .83,P < .01). Conversely,showed lower correlations with speeds evoking CS from 25-m AOT (2.86 [0.18],r = .42,P = .18) and YYIR1 (4.36 [0.11],r = .55,P = .07). The 800-m time trial (213.58 [15.84] s) was best predicted using parameters from the 25-m AOT (r = .93, SEE = 6.60 s,P < .001).Conclusions:The AOT is a valuable method of assessing performance-specific fitness, with CS from linear and 50-m-shuttle AOTs being strong predictors of, rivaling metrics from the graded exercise test. The YYIR1 offered limited utility compared with the AOT method.

Résumé :

In an earlier paper [5] we introduced the idea of an immersion f: Mm-ℝn with totally reducible focal set. Such an immersion has the property that, for all p ∈ M, the focal set with base p is a union of hyperplanes in the normal plane to f(M) at f(p). Trivially, this always holds if n = m + 1 so we only consider n > m + 1.

Résumé :

This study examined the effects of sour tart cherry juice (TC) on muscle soreness (MS) and wellbeing following a rugby union match in professional players. In a crossover design, 10 players from a senior squad in the top tier of England consumed either 2 × 30 mL servings of TC or an isocaloric cherry-flavoured control gel (CON) two days before, the day of, and two days following an 80 min match. Subjective wellbeing and MS were measured before the match (Pre), and for three days following the match (M+1, M+2, and M+3, respectively). MS was elevated from Pre at M+1 (CON, 111 ± 37 mm vs. TC 94 ± 41 mm) and M+2 (CON, 81 ± 35 mm vs. TC 72 ± 36 mm) (time effect; p = 0.0001; ηp2 = 0.821) but there were no differences between TC and CON at either time point post-exercise (p = 0.807; ηp2 = 0.035). Wellness scores were ~15% lower at M+1 (p = 0.023; ηp2 = 0.638) but there were no differences between the two conditions at any time point (p = 0.647; ηp2 = 0.160). In conclusion, tart cherry juice did not attenuate soreness or alter wellbeing in a team of professional rugby union players following a competitive match.

Résumé :

Purpose: To investigate the relationship between physical fitness and repeated high-intensity effort (RHIE) ability in elite rugby union players, depending on playing position. Method: Thirty-nine players underwent a fitness testing battery composed of a body composition assessment, upper-body strength (1-repetition maximum bench press and 1-repetition maximum bench row), lower-body strength (6-repetition maximum back squat), and power (countermovement jump, countermovement jump with arms, and 20-m sprint), as well as aerobic fitness (Bronco test) and RHIE tests over a 1-week period. Pearson linear correlations were used to quantify relationships between fitness tests and the RHIE performance outcomes (total sprint time [TST] and percentage decrement [%D]). Thereafter, a stepwise multiple regression model was used to verify the influence of physical fitness measures on RHIE ability. Results: TST was strongly to very strongly associated to body fat (BF, r = .82, P < .01), the 20-m sprint (r = .86, P < .01), countermovement jump (r = −.72, P < .01), and Bronco test (r = .90, P < .01). These fitness outcomes were related to %D, with moderate to strong associations (.82 > ∣r∣ > .54, P < .01). By playing position, similar associations were observed in forwards, but RHIE ability was only related to the 20-m sprint in backs (r = .53, P < .05). The RHIE performance model equations were TST = 13.69 + 0.01 × BF + 0.08 × Bronco + 10.20 × 20 m and %D = −14.34 + 0.11 × BF +0.18 × Bronco − 9.92 × 20 m. These models explain 88.8% and 68.2% of the variance, respectively. Conclusion: Body composition, lower-body power, and aerobic fitness were highly related with RHIE ability. However, backs expressed a different profile than forwards, suggesting that further research with larger sample sizes is needed to better understand the fitness determinants of backs’ RHIE ability.

Résumé :

Abstract Objective To evaluate the differences in subjective sleep quality, quantity, and behaviors among male and female elite rugby union athletes through two common sleep questionnaires. Materials and Methods A sample of 38 male and 27 female elite rugby union athletes filled out the Athlete Sleep Behavior Questionnaire (ASBQ) and the Pittsburgh Sleep Quality Index (PSQI). Global scores and individual items for each questionnaire were compared to assess differences between sexes. Results Male athletes reported significantly longer sleep duration (7 h 50 m ± 50 m versus 7h 12 m ± 58 m respectively; p ≤ 0.01; d = 0.70) and higher habitual sleep efficiency (88% versus 83% respectively; p < 0.05; d = 0.54) when compared with female athletes. Individual items of the ASBQ revealed significant differences between male and female athletes for five questions. Male athletes displayed higher instances of taking stimulants before training or competition and consuming alcohol within 4 hours of going to bed. Conversely, female athletes expressed greater thought or worry while in bed and a higher instance of training late at night. Discussion Male athletes displayed better self-reported sleep quality and quantity than female athletes; however, the present study highlighted that male and female elite rugby union athletes face specific challenges that differ. It appears that the differences observed between male and female elite rugby union athletes may be due to differing levels of professionalism or differences in training or competition schedules.

Let S be a finite semigroup. Consider the set p(S) of all elements of S which can be represented as a product of all the elements of S in some order. It is shown that p(S) is contained in the minimal ideal M of S and intersects each maximal subgroup H of M in essentially the same way. The main result shows that p(S) intersects H in a union of cosets of H′.

Résumé :

Purpose: To investigate the effects of repeated-sprint training in hypoxia vs in normoxia on world-level male rugby union players’ repeated-sprint ability (RSA) during an international competition period. Methods: A total of 19 players belonging to an international rugby union senior male national team performed 4 sessions of cycling repeated sprints (consisting of 3 × eight 10-s sprints with 20 s passive recovery) either in normobaric hypoxia (RSH, 3000 m; n = 10) or in normoxia (RSN, 300 m; n = 9) over a 2-wk period. Before and after the training intervention, RSA was evaluated using a cycling repeated-sprint test (6 × 10-s maximal sprint and 20-s passive recovery) performed in normoxia. Results: Significant interaction effects (all P < .05, ) between condition and time were found for RSA-related parameters. Compared with Pre, maximal power significantly improved at Post in RSH (12.84 [0.83] vs 13.63 [1.03] W·kg−1, P < .01, ) but not in RSN (13.17 [0.89] vs 13.00 [1.01] W·kg−1, P = .45, ). Mean power was also significantly enhanced from Pre to Post in RSH (11.15 [0.58] vs 11.86 [0.63] W·kg−1, P < .001, ), whereas it remained unchanged in RSN (11.54 [0.61] vs 11.75 [0.65] W·kg−1, P = .23, ). Conclusion: As few as 4 dedicated specific RSH sessions were beneficial to enhance repeated power production in world-level rugby union players. Although the improvement from RSA to game behavior remains unclear, this finding appears to be of practical relevance as only a short preparation window is available prior to international rugby union games.

Abstract. This article reviews R. M. P. Sosrokartono's thoughts about the perfect human being. He defines a perfect being as a person who is able to live up to the knowledge of ngawoelo dateng kawoelaning Goesti. In order to have such life and behavior that reflect the attributes of God by loving and maintaining the wholeness of God's creation, therefore, the alignment must be based on catur murti. That is, to be able to unite and balance feelings, thoughts, words, and actions. The union of the four components is based on the value of truth so that the actualization in life becomes the proper thought, feeling, word, and action. That is the perfect being who will become caliph on earth. Abstrak. Artikel ini mengulas pemikiran R. M. P. Sosrokartono tentang manusia paripurna. Baginya, manusia paripurna adalah manusia yang mampu menghayati ilmu ngawoelo dateng kawoelaning Goesti. Sehingga hidup dan perilakunya akan mencerminkan sifat-sifat Tuhan dengan cara mencintai dan menjaga keutuhan ciptaan Tuhan. Penyelarasan itu harus didasari oleh catur murti. Yaitu, mampu menyatukan sekaligus menyeimbangkan antara perasaan, pikiran, perkataan, dan perbuatan. Penyatuan empat komponen tersebut berdasarkan pada nilai kebenaran, sehingga penyatuan itu menjadi pikiran yang benar, perasaan yang benar, perkataan yang benar dan perbuatan yang benar. Itulah manusia paripurna yang menjadi khalifah di muka bumi.

Résumé :

Athletic performance is influenced by many factors such as the environment, diet, training and endurance or speed in physical effort and by genetic predisposition. Just a few studies have analyzed the impact of genotypes on physical performance in rugby. The aim of this study was to verify the modulation of genetic influence on rugby-specific physical performance. Twenty-seven elite rugby union players were involved in the study during the in-season phase. Molecular genotyping was performed for: angiotensin-converting enzyme (ACE rs4646994), alfa-actinin-3 (ACTN3 rs1815739) and monocarboxylate transporter 1 (MCT1 rs1049434) and their variants. Lean mass index (from skinfolds), lower-limb explosive power (countermovement jump), agility (505), speed (20 m), maximal aerobic power (Yo-yo intermittent recovery test level 1) and repeated sprint ability (12 × 20 m) were evaluated. In our rugby union players ACE and ACTN3 variants did not show any influence on athletic performance. MCT1 analysis showed that TT-variant players had the highest peak vertical power (p = 0.037) while the ones with the AA genotype were the fastest in both agility and sprint tests (p = 0.006 and p = 0.012, respectively). Considering the T-dominant model, the AA genotype remains the fastest in both tests (agility: p = 0.013, speed: p = 0.017). Only the MCT1 rs1049434 A allele seems to be advantageous for elite rugby union players, particularly when power and speed are required.

Résumé :

In this paper, we deal with the classical Statistical Learning Theory’s problem of bounding, with high probability, the true risk R(h) of a hypothesis h chosen from a set H of m hypotheses. The Union Bound (UB) allows one to state that PLR^(h),δqh≤R(h)≤UR^(h),δph≥1−δ where R^(h) is the empirical errors, if it is possible to prove that P{R(h)≥L(R^(h),δ)}≥1−δ and P{R(h)≤U(R^(h),δ)}≥1−δ, when h, qh, and ph are chosen before seeing the data such that qh,ph∈[0,1] and ∑h∈H(qh+ph)=1. If no a priori information is available qh and ph are set to 12m, namely equally distributed. This approach gives poor results since, as a matter of fact, a learning procedure targets just particular hypotheses, namely hypotheses with small empirical error, disregarding the others. In this work we set the qh and ph in a distribution-dependent way increasing the probability of being chosen to function with small true risk. We will call this proposal Distribution-Dependent Weighted UB (DDWUB) and we will retrieve the sufficient conditions on the choice of qh and ph that state that DDWUB outperforms or, in the worst case, degenerates into UB. Furthermore, theoretical and numerical results will show the applicability, the validity, and the potentiality of DDWUB.

Résumé :

At the beginning of 1844, the Revd John Flowerdew Colls, Anglican minister of Duke Street Chapel, St James's Park, London, published Utilitarianism unmasked, a vitriolic attack on Jeremy Bentham (1748–1832), the philosopher, jurisprudent, and advocate of reform. ‘The writer's main object’, the advertisement which prefaces the work grandiloquently announces, ‘has been to expose, in all its naked deformity, the hollowness and deceitfulness of the so-much-vaunted principle falsely called the Greatest happiness principle’, which formed the basis of Bentham's philosophical system. But apart from a few desultory remarks on utilitarianism – such as a belaboured attempt to connect it with Robert Owen's socialism (p. 33) – Colls devoted his energies to undermining Bentham's ideas by pouring scorn and ridicule on Bentham himself.

Résumé :

Rugby union (RU) is a field-based team sport with a large number of high-intensity actions such as sprinting, change of direction, tackling, scrummaging, rucking, and mauling. Competitive success in female RU has previously been related to anthropometric and physical characteristics, and with the recent introduction of professionalism in female rugby, characterizing such physical attributes may provide insight into selection and training processes. Purpose: To identify anthropometric and physical characteristics of competitive female RU players and differences between playing positions. Methods: Twenty-two players were recruited from the top tier of female RU in the United Kingdom during the 2018–2019 Premiership season. Players were split into forwards and backs and underwent body composition testing via dual-X-ray absorptiometry and physical characteristic tests (10- and 20-m speed, 1-repetition-maximum bench press and squat, countermovement jump, drop jump, isometric midthigh pull, and 1200-m shuttle). Results: Moderate to large significant differences between playing positions in both anthropometric and physical characteristics were found (P < .01). Forwards displayed greater body mass (P = .03), fat mass (P = .01), and absolute upper-body strength (P = .03), whereas backs demonstrated superior countermovement jump height (P = .01), drop jump height (P = .01), greater reactive strength (P = .03), and speed (P = .03). Conclusion: These findings provide practitioners with a greater understanding of anthropometric and physical characteristics of professional female RU players.

Résumé :

This paper tightens the classical Poincaré–Bendixson theory for a positively invariant, simply-connected compact set M in a continuously differentiable planar vector field by further characterizing for any point p ∈ M , the composition of the limit sets ω ( p ) and α ( p ) after counting separately the fixed points on M 's boundary and interior. In particular, when M contains finitely many boundary but no interior fixed points, ω ( p ) contains only a single fixed point, and when M may have infinitely many boundary but no interior fixed points, ω ( p ) can, in addition, be a continuum of fixed points. When M contains only one interior and finitely many boundary fixed points, ω ( p ) or α ( p ) contains exclusively a fixed point, a closed orbit or the union of the interior fixed point and homoclinic orbits joining it to itself. When M contains in general a finite number of fixed points and neither ω ( p ) nor α ( p ) is a closed orbit or contains just a fixed point, at least one of ω ( p ) and α ( p ) excludes all boundary fixed points and consists only of a number of the interior fixed points and orbits connecting them.

Résumé :

Background: We sought to determine the time course of changes in neuromuscular performance and muscle damage following a single rugby union match. Methods: Fourteen male amateur rugby players (28.9 ± 3.5 yrs; 1.7 ± 5.1 m; 86.1 ± 11.1 kg) participated. Plasma activity of creatine kinase ([CK]) and lactate dehydrogenase (LDH), L-run test (change of direction) and 30-m sprint (T30; speed) with 10-m lap time (T10; acceleration) were assessed on six occasions: one week before the match (PRE) and immediately, 24, 48, 72, and 96 h post-match. Results: Relative to PRE, LDH was elevated immediately post-match (+33.6% ± 13.6%; p < 0.001) and [CK] was elevated immediately (+64.1% ± 38.8%, p = 0.001) and 24 h post-match (+352% ± 317%; p = 0.024). L-run test time increased 16.0 ± 8.7% relative to PRE at 24 h post (p < 0.001) and remained elevated through 96 h post-match (p < 0.05). T10 and T30 times increased relative to PRE immediately post-match (+12.0% ± 10.4%, p = 0.008; and +6.1% ± 4.9%; p = 0.006, respectively), though T30 times were similar to baseline by 48 h post-match whereas T10 times remained elevated through 72 h post-match. Conclusions: A single, competitive rugby union match induces significant muscle damage and performance decrements with distinct time courses of recovery in amateur athletes. Notably, change of direction attributes (i.e., L-run) appear to have the longest time course to full recovery.

Purpose:To assess the effects of different modes of morning (AM) exercise on afternoon (PM) performance and salivary hormone responses in professional rugby union players.Methods:On 4 occasions (randomized, crossover design), 15 professional rugby players provided AM (~8 AM) and PM (~2 PM) saliva samples before PM assessments of countermovement-jump height, reaction time, and repeated-sprint ability. Control (passive rest), weights (bench press: 5 × 10 repetitions, 75% 1-repetition maximum, 90-s intraset recovery), cycling (6 × 6-s maximal sprint cycling, 7.5% body mass load, 54-s intraset recovery), and running (6 × 40-m maximal sprints, 20-s intraset recovery) interventions preceded (~5 h) PM testing.Results:PM sprint performance improved (P < .05) after weights (>0.15 ± 0.19 s, >2.04% ± 2.46%) and running (>0.15 ± 0.17 s, >2.12% ± 2.22%) but not cycling (P > .05). PM jump height increased after cycling (0.012 ± 0.009 m, 2.31% ± 1.76%, P < .001) and running (0.020 ± 0.009 m, 3.90% ± 1.79%, P < .001) but not weights (P = .936). Reaction time remained unchanged between trials (P = .379). Relative to control (131 ± 21 pg/mL), PM testosterone was greater in weights (21 ± 23 pg/mL, 17% ± 18%, P = .002) and running (28 ± 26 pg/mL, 22% ± 20%, P = .001) but not cycling (P = .072). Salivary cortisol was unaffected by AM exercise (P = .540).Conclusions:All modes of AM exercise improved at least 1 marker of PM performance, but running appeared the most beneficial to professional rugby union players. A rationale therefore exists for preceding PM competition with AM exercise.

Résumé :

Change-of-direction (COD) ability is an essential component of rugby union. As most COD tests use total time to measure COD performance, the COD deficit has been developed as a metric to isolate COD ability independent of linear sprint speed. This study investigated relationships between sprint time, 505 time, and COD deficit in collegiate women’s rugby union players. Seventeen players from the one team performed a 20-m sprint (0-5, 0-10, and 0-20 m intervals were measured), and the 505 from each leg. The COD deficit for both legs was calculated as the difference between average 505 and 10-m time. Correlations were calculated between the 505 and COD deficit with the sprint intervals (p ≤ 0.05). To compare 505 time and COD deficit, z-scores were derived; the difference in these scores were evaluated for each participant. The COD deficit did not correlate with the sprint interval times (r = -0.370 to -0.045). Right-leg 505 time did correlate with the 0-10 and 0-20 m intervals (r = 0.483-552). Six of 17 participants for the left leg, and five of 17 for the right leg, were classified differently for COD ability when comparing standardized scores for 505 time versus COD deficit. More than half the participants (53-59%) had meaningful differences between 505 time and COD deficit for each leg. These results suggested that the COD deficit may be a more isolated measure of COD ability and provided a different measure of this ability compared to 505 time in collegiate women’s rugby union players.

Résumé :

Objective. To investigate changes in the physical fitness characteristics of elite women’s rugby union players over a competitive season.Methods. Thirty-two elite women’s rugby union players, all members of the South African Rugby Union High Performance Squad, were sub-divided into 2 positional categories of 17 forwards and 15 backs, respectively, and assessed pre-, mid- and post-competition season. Players underwent anthropometric (stature, body mass and sum of 7 skinfolds) and physical performance measurements (vertical jump, 10 m and 40 m sprint, 1 repetition maximum (1RM) bench press and multi-stage shuttle-run test).Analysis. A 2-factor analysis of variance was used to evaluate differences in physical fitness variables between and within playing positions over the competition season (p<0.01).Results. In both groups, no significant changes were detected in the sum of skinfolds, vertical jump height, 1RM bench press and multi-stage shuttle-run test scores throughout the season. However, sprint times (10 m and 40 m) significantly increased and then decreased for both groups between the early (pre- to mid-season) and later phases of the season (mid- to post-season), respectively.Conclusion. The results suggest that, for improvement in physical fitness, players need to train at higher loads, especially in the preparatory phase. Thereafter, they must take measures to actively maintain these gains throughout the competitive season. Direct supervision of their conditioning should be encouraged.

Résumé :

Abstract Warm-up protocols have the potential to cause an acute enhancement of dynamic sprinting performance. The purpose of this study was to evaluate the effects of three repetition specific gluteal activation warm-up protocols on acceleration performance in male rugby union players. Forty male academy rugby union players were randomly assigned to one of 4 groups (control, 5, 10 or 15 repetition gluteal activation group) and performed 10 m sprints at baseline and 30 s, 2, 4, 6 and 8 min after their specific intervention protocol. Five and ten meter sprint times were the dependent variable and dual-beam timing gates were used to record all sprint times. Repeated measures analysis of variance found no significant improvement in 5 and 10 m sprint times between baseline and post warm-up scores (p ≥ 0.05) for all groups. There were no reported significant differences between groups at any of the rest interval time points (p ≥ 0.05). However, when individual responses to the warm-up protocols were analyzed, the 15 repetition gluteal activation group had faster 10 m times post-intervention and this improvement was significant (p = 0.021). These results would indicate that there is no specific rest interval for any of the gluteal interventions that results in a potentiation effect on acceleration performance. However, the individual response analysis would seem to indicate that a 15 repetition gluteal activation warm-up protocol has a potentiating effect on acceleration performance provided that the rest interval is adequately and individually determined.

Résumé :

Background: A pilon fracture is a distal tibial metaphyseal fracture that involves the ankle joint. Distal tibia fractures include extra-articular fractures of the metaphysis and the more severe intraarticular tibial plafond or pilon fractures. Several treatment methods have been recommended for the treatment of these injuries, with a recent emphasis on minimally invasive techniques. This research studies the outcome of a malleolar locking plate (M) versus a metaphyseal locking plate (P) in the management of distal tibial (Pilon) fracture. Methods: Distal tibial M and P were used to treat 80 cases of tibial pilon fracture. The study examined the use of anterior/ anteromedial approach for tibia and posterolateral/ lateral fibular fixation. Results: The male to female gender ratio was 2.63 in M and 1.35 in P. Mean age was 57.03±15.93 (M) and 52.1±12.788 (P). Surgeries were mostly done within 1 day to 1 week. Mean hospital stay was 6.43±4.545 (M) and 4.93±4.676 (P). The mean lower extremity functional score (LEFS) was 66.55 (M) and 67.15 (P) with 83.56% maximal function. 3 P cases had infections. No infections were seen in M group at the end of the 12th week follow-up. Conclusions: The results of the study indicate that there is no significant difference in terms of LEFS criteria, union, fracture alignment, range of motion (knee and ankle), infection, and other outcome measures between M fixation and P in the treatment of distal tibia fracture in adults.

Résumé :

The purpose of this study was to compare measures of anthropometry characteristics and physical fitness performance between rugby union players (17.9 ± 0.5 years old) recruited (n = 39) and non-recruited (n = 145) to the Portuguese under-19 (U19) national team, controlling for their playing position (forwards or backs). Standardized anthropometric, physical, and performance assessment tests included players’ body mass and height, push up and pull-up test, squat test, sit-and-reach test, 20 m shuttle run test, flexed arm hang test, Sargent test, handgrip strength test, Illinois agility test, and 20-m and 50-m sprint test. Results showed that recruited forwards players had better agility scores (p = 0.02, ES = −0.55) than the non-recruited forwards, whereas recruited backs players had higher right (p < 0.01, ES = 0.84) and left (p = 0.01, ES = 0.74) handgrip strength scores than their counterparts. Logistic regression showed that better agility (for the forwards) and right handgrip strength scores (for the backs) were the only variables significantly associated with an increased likelihood of being recruited to the national team. In sum, these findings suggest that certain well-developed physical qualities, namely, agility for the forwards players and upper-body strength for the back players, partially explain the selection of U19 rugby players to their national team.

Résumé :

The aims of this study in elite youth French players were to 1) describe the anthropometric and physical characteristics of international and non-international players from U16 to U20, and 2) compare these characteristics across age categories and playing standard (international or non-international). Altogether, 1423 players from the French Rugby Federation’s academies participated in a physical testing battery, part of its national young player development pathway. From seasons 2010 to 2020, players were assessed for anthropometric (body mass and height), off-field (bench press; isometric squat, vertical jump) and on-field physical characteristics (aerobic capacity: maximal aerobic speed [MAS]; speed: 10-m, 50-m sprint). A 2-way mixed model analysis of variance (ANOVA) was used to compare physical characteristics across age categories and playing standards. Two separate models were used for forwards and backs. A main statistical effect was observed for age category and playing standard (range p < 0.05 –p < 0.001). Pair-wise category comparisons showed that older players were generally taller, heavier, stronger, faster and demonstrated better aerobic qualities than younger peers. The same results were observed for INT compared with NI players while INT forwards were also taller and heavier than NI peers (range p < 0.01 –p < 0.001). Findings revealed a clear progression in anthropometric characteristics and physical qualities throughout the age development pathway in elite young French rugby players. Findings also identified certain physical qualities (strength, power and speed) necessary at younger levels to achieve international standard.

Résumé :

ObjectivesOur aim of this study was to quantify the physical demands of elite rugby union players by each position as a step towards designing position-specific training programme using a Global Positioning System/accelerometer system.MethodsThis study was performed as a retrospective observational study. Data were obtained from 45 official matches. The sample size used for the analysis was 298. The per-match total distances, accelerations and impacts were calculated and statistically compared for the forwards and backs and for individual positions.ResultsTotal distances for the forwards and backs were 5731.1±507.8 and 6392.1±646.8 m, respectively. The high-velocity running distances (>18.0 km/hour) covered by the forwards and backs were 317.4±136.9 and 715.0±242.9 m, respectively. The number of accelerations (>1.5 m/s2) for the forwards and backs were 76.3±18.9 and 100.8±19.6 times, respectively, and the number of high impacts (>10 g) were 48.0±46.9 and 35.6±28.3 times for the forwards and backs, respectively. All characteristics were significantly different between the forwards and backs (p<0.05). The per-position characteristics were also calculated. Within the backs, scrum half (SH) and wingers (WTBs) covered high-velocity running significantly higher distance than fly-half (SH d=2.571, WTBs d=1.556) and centres (SH d=1.299, WTBs d=0.685) (p<0.05).ConclusionBy clarifying the physical demands according to the positions, it will be possible to create optimised position-specific training programmes.

Résumé :

The categorical treatment of fuzzy modules presents some problems, due to the well known fact that the category of fuzzy modules is not abelian, and even not normal. Our aim is to give a representation of the category of fuzzy modules inside a generalized category of modules, in fact, a functor category, Mod−P, which is a Grothendieck category. To do that, first we consider the preadditive category P, defined by the interval P=(0,1], to build a torsionfree class J in Mod−P, and a hereditary torsion theory in Mod−P, to finally identify equivalence classes of fuzzy submodules of a module M with F-pair, which are pair (G,F), of decreasing gradual submodules of M, where G belongs to J, satisfying G=Fd, and ∪αF(α) is a disjoint union of F(1) and F(α)\G(α), where α is running in (0,1].

Résumé :

Let R be a commutative ring with identity, I its proper ideal and M be a unitary R-module. In this paper, we introduce and study a kind of graph structure of an R-module M with respect to proper ideal I, denoted by ΓI(RM) or simply ΓI(M). It is the (undirected) graph with the vertex set M\{0} and two distinct vertices x and y are adjacent if and only if [x : M][y : M] ⊆ I. Clearly, the zero-divisor graph of R is a subgraph of Γ0(R); this is an important result on the definition. We prove that if ann R(M) ⊆ I and H is the subgraph of ΓI(M) induced by the set of all non-isolated vertices, then diam (H) ≤ 3 and gr (ΓI(M)) ∈ {3, 4, ∞}. Also, we prove that if Spec (R) and ω(Γ Nil (R)(M)) are finite, then χ(Γ Nil (R)(M)) ≤ ∣ Spec (R)∣ + ω(Γ Nil (R)(M)). Moreover, for a secondary R-module M and prime ideal P, we determine the chromatic number and the clique number of ΓP(M), where ann R(M) ⊆ P. Among other results, it is proved that for a semisimple R-module M with ann R(M) ⊆ I, ΓI(M) is a forest if and only if ΓI(M) is a union of isolated vertices or a star.

Résumé :

The article focuses on the perception of Orthodoxy and Uniatism within Russian intellectual circles on the eve of the reunification of Belarusian Uniates with the Orthodox Church in 1839. The article also examines the religious perspectives of both governmental figures (S. S. Uvarov, M. M. Speransky) and public figures (N. M. Karamzin, A. S. Sturdza, A. S. Pushkin, N. G. Ustryalov, D. N. Bantysh-Kamensky, I. I. Sreznevsky, P. Ya. Chaadaev). In the 1810s and 1830s, secular circles began to formulate ideas about Orthodoxy as a religion of love, firmly rooted in the original Christian tradition. Orthodoxy was regarded as a religion characterized by dogmatic certainty, devoid of relativism and false mysticism. The primary distinction from Catholicism lay in the absence of a pursuit for secular power, and consequently, a rejection of the practice of violence. Additionally, the Orthodox Church was viewed as the historical church of the Russian people. The author of the article concludes that by this time, a significant segment of society, particularly those concerned with religious matters, had already developed relatively stable ideas about the union. The union was perceived as the result of religious manipulation and coercion by papal Rome, as well as the enticement of certain Western Russian church hierarchs. The article underscores the Orthodox population’s rejection of the union within the Polish-Lithuanian Commonwealth, particularly among the common people. Hence, the effort to overcome the union was deemed justified. Furthermore, the Uniates could not be regarded as fully integrated members of the Russian people until they were reunited with both the Church and the Russian national spirit. Within the framework of the intellectual circles’ ideas that emerged during that period, religious and secular reasoning were closely interwoven and found historical validation.

Résumé :

the article is devoted to the problem of the formation and functioning of the Komi writers’ organization in the period 1920–50s. A significant stage in its history is the holding of the I All-Union Congress of Soviet Writers (Moscow, 1934) and the participation of the Komi delegation in it. The article examines the forms and degree of influence of the results of the congress on the work of the Komi Writers’ Union, the development of national literature and journalism. Objective: determination of the main trends in the development of the Komi literary process as a result of the I All-Union Congress of Soviet Writers. Research materials: archive documents, articles in periodical press, verbatim report of the I All-Union Congress of Soviet Writers. Results and novelty of the research: the delegates to the I All-Union Congress of Soviet Writers with the casting vote from the Komi Writers Union were M. P. Doronin and V. T. Chistalev. The article is the first to study in detail the fact of their participation in this event. It has been established that the event influenced the further work of the Komi Writers Union and the process of development of literature. It is concluded that the results of the congress of the Communist Party of Bolsheviks, as well as establishing external literary connections, attracting writers’ attention to national folklore, and organizing work with novice authors.

Résumé :

AbstractThe problems on isomorphic classification and quasiequivalence of bases are studied for the class of mixed F-, DF-power series spaces, i.e. the spaces of the following kind where ai (p, q) = exp((p - λiq)ai), p,q ∈ ℕ, and λ = (λi)i∈ℕ, a = (ai)i∈ℕ are some sequences of positive numbers. These spaces, up to isomorphisms, are basis subspaces of tensor products of power series spaces of F- and DF-types, respectively. The mrectangle characteristic of the space G(λ a) is defined as the number of members of the sequence (ïiÒ ai)i2N which are contained in the union of m rectangles Pk = (δk, εk] ✗ (τk, tk], k = 1, 2 , . . . , m. It is shown that each m-rectangle characteristic is an invariant on the considered class under some proper definition of an equivalency relation. The main tool are new compound invariants, which combine some version of the classical approximative dimensions (Kolmogorov, Pełczynski) with appropriate geometrical and interpolational operations under neighborhoods of the origin (taken from a given basis).

Résumé :

There is an ongoing search on how to enhance the sprint performance of athletes. One should likely start investigating beyond traditional sport-training techniques about enhancing the sprinting ability of an athlete. Female rugby players were randomly assigned to one of the two groups; an experimental group (n = 5) and a control group (n = 5). Data were collected during pre-season and end-season on hamstring flexibility and sprint performance. Unpaired t-tests with an alpha level of p ≤ 0.05, Pearson correlation coefficient for the correlation. The experimental group significantly improved their straight leg raise test (SLR) by 29.1 ± 15.3-degrees (mean % change ± 95% CI, p < 0.05) and 5 m sprint time -10.4 ± 10.2 % compared to the control group 2.9 ± 15.3-degree (p = 0.05), and time difference of 9.9 ± 6.1% respectively. There was also a moderate negative correlation between SLR and 5 m sprint performance time (r = -0.29, p < 0.05 statistical significance. Results indicate that a 12-week yoga training helped improve the hamstring flexibility and performance of the 5 m acceleration phases of the 20 m sprint of rugby union players compared to a control group. Yoga helped rugby players to improve their hamstring flexibility when practiced alongside normal rugby training but maybe did little to improve sprint measures greater than 5 m performance during the season.

Résumé :

Water in the Miedwie Lake were the subjects of a five-year study (2008-2010). Total alkaline phosphatase activity was determined seven times a year in these environments. The study on the water demonstrated that the top sublittoral layer (1 m) featured the highest alkaline phosphatase activity among all the analyzed zones. A study of seasonal fluctuations showed that a maximum total alkaline phosphatase activity, both in the water occurred in spring (May) and summer (July, August). Basing on this parameter no increase in eutrophication process in the Miedwie Lake was determined in the course of a 3-year study.

Résumé :

Purpose: To test the relationships between maximum and relative strength (MS and RS), absolute and relative peak force (PF and RPF), and strength deficit (SDef), with sprint and jump performance, and to compare these mechanical variables between elite sprinters and professional rugby union players. Methods: Thirty-five male rugby union players and 30 male sprinters performed vertical jumps, 30-m sprint, and half-squat 1-repetition maximum (1RM), where these force-related parameters were collected. Pearson correlation coefficients were used to test the relationships between the variables. An independent t test and magnitude-based inferences compared the mechanical variables between sprinters and rugby players. Results: Almost certain significant differences were observed for jump and sprint performance between groups (P < .0001). The rugby union players demonstrated a likely significant higher MS (P = .03) but a very likely lower RS (P = .007) than the sprinters. No significant differences were observed for PF between them. The sprinters exhibited an almost certain significant higher RPF than the rugby players (P < .0001). Furthermore, the rugby players demonstrated almost certain to likely significant higher SDef from 40% to 70% 1RM (P < .05) compared with the sprinters. Overall, all strength-derived parameters were significantly related to functional performance. Conclusions: Elite sprinters present higher levels of RS and RPF, lower levels of SDef, and better sprint and jump performance than professional rugby players. Relative strength-derived values (RS and RPF) and SDef are significantly associated with speed–power measures and may be used as effective and practical indicators of athletic performance.

Résumé :

Given a manifold N and a number m, we study the following question: is the set of isotopy classes of embeddingsN → Smfinite? In case when the manifold N is a sphere the answer was given by A. Haefliger in 1966. In case when the manifold N is a disjoint union of spheres the answer was given by D. Crowley, S. Ferry and the author in 2011. We consider the next natural case when N is a product of two spheres. In the following theorem, FCS (i, j) ⊂ ℤ2 is a specific set depending only on the parity of i and j which is defined in the paper. Theorem.Assume thatm > 2p + q + 2andm < p + 3q/2 + 2. Then the set of isotopy classes ofC1-smooth embeddingsSp × Sq → Smis infinite if and only if eitherq + 1orp + q + 1is divisible by 4, or there exists a point(x, y)in the set FCS (m - p - q, m - q)such that(m - p - q - 2)x + (m - q - 2)y = m - 3. Our approach is based on a group structure on the set of embeddings and a new exact sequence, which in some sense reduces the classification of embeddings Sp × Sq → Sm to the classification of embeddings Sp+q ⊔ Sq → Sm and Dp × Sq → Sm. The latter classification problems are reduced to homotopy ones, which are solved rationally.

Résumé :

This study compared the mechanical bending and torsional properties of intramedullary nail fixation and lag screw fixation for tibiotalocalcaneal arthrodesis. Seven matched pairs of human cadaver lower extremities were studied, with one hindfoot in each pair stabilized with a 12 mm × 150 mm interlocked intramedullary nail inserted retrograde across the subtalar and ankle joints. The contralateral hindfoot was stabilized with two crossed 6.5 mm cannulated screws inserted across both the ankle and subtalar joints. Specimens were subjected to cantilever bending tests in plantarflexion, dorsiflexion, inversion, and eversion and to torsional tests in internal and external rotation. The intramedullary nail construct was significantly ( P < 0.05) stiffer than the crossed lag screw construct in all four bending directions and both rotational directions: plantarflexion (nail, 42.8 N/mm; screws, 16.4 N/mm; P = 0.0003), dorsiflexion (nail, 43.0 N/mm; screws, 10.3 N/mm; P = 0.0005), inversion (nail, 37.7 N/mm; screws, 12.3 N/mm; P = 0.0024), eversion (nail, 35.4 N/mm; screws, 10.8 N/mm; P = 0.0004), internal rotation (nail, 1.29 N-m/°; screws, 0.82 N-m/°; P = 0.01), external rotation (nail, 1.35 N-m/°; screws, 0.44 N-m/°; P = 0.0001). Intramedullary fixation is biomechanically stiffer than crossed lag screws in all bending and torsional directions tested and therefore this construct may aid in maintaining alignment of the hindfoot during union and may help increase fusion rate through increased stability of the internal fixation.
