Abstract. The aim of this study was to examine whether athletes differ from nonathletes regarding their mental rotation performance. Furthermore, it investigated whether athletes doing sports requiring distinguishable levels of mental rotation (orienteering, gymnastics, running), as well as varying with respect to having an egocentric (gymnastics) or an allocentric perspective (orienteering), differ from each other. Therefore, the Mental Rotations Test (MRT) was carried out with 20 orienteers, 20 gymnasts, 20 runners, and 20 nonathletes. The results indicate large differences in mental rotation performance, with those actively doing sports outperforming the nonathletes. Analyses for the specific groups showed that orienteers and gymnasts differed from the nonathletes, whereas endurance runners did not. Contrary to expectations, the mental rotation performance of gymnasts did not differ from that of orienteers. This study also revealed gender differences in favor of men. Implications regarding a differentiated view of the connection between specific sports and mental rotation performance are discussed.

Full textAbstract:
Sex differences in mental rotation skills are a robust finding in small-scale laboratory-based studies of spatial cognition. There is almost no evidence in the literature, however, relating these skills to performance on spatial tasks in large-scale, real-world activities such as navigating in a new city or in the woods. This study investigates the connections between mental rotation skills as measured by the Vandenburg-Kuse Mental Rotations test and the performance of college students ( n = 211) navigating a 6-km orienteering course. The results indicate that mental rotation skills are significantly correlated with wayfinding performance on an orienteering task. The findings also replicate sex differences in spatial ability as found in laboratory-scale studies. However, the findings complicate the discussion of mental rotation skills and sex because women often performed as well as men despite having lower mean test scores. This suggests that mental rotation ability may not be as necessary for some women's wayfinding as it is for men's navigation.

Routing problems have many practical applications in distribution and logistics management. The Traveling Salesman Problem (TSP) and its variants lie at the heart of routing problems. The Orienteering Problem (OP) is a subset selection version of well-known TSP which comes from an outdoor sport played on mountains. In the OP, the traveller must finish its journey within a predetermined time (cost, distance), and gets a gain (profit, reward) from the visited nodes. The objective is to maximize the total gain that the traveller collects during the predetermined time. The OP is also named as the selective TSP since not all cities have to be visited. The Team Orienteering Problem (TOP) is the extension of OP by multiple-traveller. As far as we know, there exist a few formulations for the TOP. In this paper we present two new integer linear programming formulations (ILPFs) for the TOP with O(n2) binary variables and O(n2) constraints, where n is the number of nodes on the underlying graph. The proposed formulations can be directly used for the OP when we take the number of traveller as one. We demonstrate that, additional restrictions and/or side conditions can be easily imported for both of the formulations. The performance of our formulations is tested on the benchmark instances from the literature. The benchmark instances are solved via CPLEX 12.6 by using the proposed and existing formulations. The computational experiments demonstrate that both of the new formulations outperform the existing one. The new formulations are capable of solving optimally most of the benchmark instances, which have solved by using special heuristics so far. As a result, the proposed formulations can be used to find the optimal solution of small- and moderate-size real life OP and TOP by using an optimizer.

Full textAbstract:
Purpose:Jumping and hopping are used to measure lower-body muscle power, stiffness, and stretch-shortening-cycle utilization in sports, with several studies reporting correlations between such measures and sprinting and/or running abilities in athletes. Neither jumping and hopping nor correlations with sprinting and/or running have been examined in orienteering athletes.Methods:The authors investigated squat jump (SJ), countermovement jump (CMJ), standing long jump (SLJ), and hopping performed by 8 elite and 8 amateur male foot-orienteering athletes (29 ± 7 y, 183 ± 5 cm, 73 ± 7 kg) and possible correlations to road, path, and forest running and sprinting performance, as well as running economy, velocity at anaerobic threshold, and peak oxygen uptake (VO2peak) from treadmill assessments.Results:During SJs and CMJs, elites demonstrated superior relative peak forces, times to peak force, and prestretch augmentation, albeit lower SJ heights and peak powers. Between-groups differences were unclear for CMJ heights, hopping stiffness, and most SLJ parameters. Large pairwise correlations were observed between relative peak and time to peak forces and sprinting velocities; time to peak forces and running velocities; and prestretch augmentation and forest-running velocities. Prestretch augmentation and time to peak forces were moderately correlated to VO2peak. Correlations between running economy and jumping or hopping were small or trivial.Conclusions:Overall, the elites exhibited superior stretch-shortening-cycle utilization and rapid generation of high relative maximal forces, especially vertically. These functional measures were more closely related to sprinting and/or running abilities, indicating benefits of lower-body training in orienteering.

Full textAbstract:
The article deals with analysis of mental maps which were obtained by questioning athletes – orienteering runners. Using the prerequisite of measurability of their sports performance, it is possible to measure the accuracy of assessment methods of mental maps. Thirty mental maps were acquired via a two-section questionnaire; they were assessed with the help of two methods – frequency measurement and determined weights and criteria. The results of the first method were visualised using software into aggregated maps which enable an overall view. The second method provides individual point of view on each athlete and their performance abilities. Comparison of both methods proves the initial hypothesis.

Abstract Aim The aim of this study was to examine if simulating an unknown competition terrain with the computer game Catching Features improved orienteers performance in the real terrain compared to a terrain they had not simulated. Method This study examined the effect of simulation by asking elite level orienteers to simulate an unknown terrain with a computer programme for approximately one hour per day, for six days prior to an orienteering test. The participants were divided into two matched groups and one group simulated one forest terrain while the other group simulated another forest terrain. On the test day the participants ran one course in each forest terrain, in a crossover-type design. Results This study shows that simulation of an unknown terrain did not statistically significant increase an orienteers performance, however it had a small effect on orienteering and navigational performance indices. The use of simulation also had a large impact on how well the participants felt they prepared for the race. Conclusions Although simulation of an unknown terrain increases an orienteer’s self-rating of prior knowledge of the terrain, there was no clear improvement in race performance. Terrain simulation had a small effect on navigational performance, possibly at the cost of a slower running speed. This may have been as a result of an increased awareness of the difficulty to relocate in the terrain after simulation, which may have prompted orienteers to try to follow a more detailed terrain model to avoid navigational errors. Following a more detailed model may have cost them as much time as they gained from not making mistakes and this resulted in no change in race performance. In the flat terrain that was tested there were not many challenging route choices and it was not possible to detect any effect on the route choice performance by simulation.

The complex physiology of orienteering performance is not well understood but recent
advances in technology allow for more in-depth investigation. The purpose of this
study was to develop and validate physiological field tests for elite orienteers in
Australia.
Seven male and three female elite orienteers volunteered to take part in the study.
Subjects completed an incremental fixed-distance (803m) trial in Australian forest
terrain, paced by a bicycle equipped with a speedometer. This was replicated in the
laboratory using a 4.5% grade for treadmill running. Subjects also completed four
(males) or three (females) laps of a 1340m terrain loop incorporating uphill, track and
downhill sections. Subjects then repeated this test in the laboratory, with treadmill grade
manipulated to replicate the gradient profile of each section. Heart rate (HR) and
oxygen uptake (VCh) were recorded continuously with telemetry during each stage/lap.
Blood [La] and RPE were recorded after each stage/lap.
In the incremental tests, no significant differences (p=0.05 level) were observed in HR,
VO2, blood [La] or RPE between the Field test, and its Laboratory replication over the
entire range of speeds tested. The actual speeds run during the Field tests were
significantly faster than the Laboratory test at the slowest speed (8 kmh- 1 ) attempted,
and slower at the fastest speed (18 km-h-1) attempted. In the time-trial tests, no
significant differences were observed in HR, VO2, blood [La] or RPE between the
Field test and its Laboratory replication. The running speeds in the Field tests were
significantly slower than the Laboratory tests. Running speed appeared inversely
related to the course profile and the terrain also affected the speeds that could be
achieved. Despite the changes in the course profile, the physiological responses to the
course were maintained within a narrow range at a high level (-95% of maximal heart
rate, 80-90% of VO2max, blood [La] -10 mM) for the duration of the 20-25 minute test.
The Field tests that were developed in this study for elite orienteers in Australian forest
terrain were successfully validated by replicating the protocols in a Laboratory setting.

Full textAbstract:
The present study aimed to examine how physical exertion influences cognitive performance.Orienteers (n = 23) competing at primarily a national to international level were recruited toparticipate. A randomised control trial using a cross-over research design required participantsto complete two trials measuring performance over a duration of 35 minutes. Specifically, inone trial participants undertook a cognitive testing protocol divided into five blocks comprisedof three separate cognitive tests that each lasted approximately one minute, between each testparticipants rested for one minute (i.e., one minute testing, followed by one minute resting fora duration of 35 minutes). The other trial required participants to complete the same cognitivetesting protocol whilst simultaneous completing a cycling time trial (i.e., aiming to cycle amaximum distance within the time of 35 minutes). Analyses revealed participants performedsignificantly worse on the cognitive tests whilst simultaneously completing the cycling timetrial. Upon closer scrutiny of the individual tests, designed to measure the cognitive functionsof decision-making, working memory, and updating, a similar trend in performance wasobserved although it was not found to be statistically significant. The findings of the presentstudy highlights implications for athletes, coaches, and sports psychologists in attempts tooptimise sport performance and minimize cognitive impairments during physical exertion. Thestudy supports the need for greater ecological validity in the investigation of cognitiveperformance in sport science research. The findings of the present study indicate that appliedsport psychology research may be enhanced by the use of research designs comprised ofcognitive tests that more closely replicate the cognitive demands of competition settings.Denna studie syftade till att undersöka hur fysisk ansträngning påverkar kognitivprestation. Urvalet bestod av orienterare tävlandes på huvudsakligen nationell tillinternationell nivå (n = 23). Studien var en randomiserad korsstudie där deltagarna genomfördekognitiva tester vid två försökstillfällen på 35 minuter vardera. Under det ena försökstillfälletgenomförde deltagarna ett kognitivt testprotokoll, indelat i fem block innehållande tre testervardera, där varje test varade i ungefär en minut, följt av en minuts vila mellan testerna (dvs.en minuts testning, följt av en minuts vila med en varaktighet på 35 minuter). Det andraförsökstillfället bestod av att deltagarna genomförde samma kognitiva testprotokoll samtidigtsom de cyklade, med målet att komma så lågt som möjligt i distans under 35 minuter.Resultaten visade på signifikant lägre kognitiv prestation när deltagarna cyklade samtidigt.Genom närmare analys av varje enskilt test (som ämnade mäta de kognitiva funktionernabeslutsfattande, arbetsminne och uppdatering) hittades samma trend, men utan signifikans.Fynden kan vara av vikt för idrottare, tränare och idrottspsykologer i deras arbete för attoptimera prestation och minimera kognitiv försämring under fysisk ansträngning. De stödjeräven behovet av ekologisk validitet i studier ämnade att undersöka kognitiv prestation inomidrott. Vidare indikerar fynden att tillämpad idrottspsykologisk forskning kan förbättras genomatt använda en forskningsdesign innehållande kognitiva test som är mer jämförbara med dekognitiva utmaningar idrottare ställs inför under tävlingssammanhang.

Full textAbstract:
In male athletes from different sports, isokinetic knee extensor, and in orienteers also plantar flexor peak torque (PT), contractional work (CW) and integrated surface electromyograms (iEMG) were analysed. Single contraction PT, CW and iEMG in sprinters and marathon runners were significantly correlated to the cross-sectional area (CSA) of m. quadriceps, and to the Type II fibre area of m. vastus lateralis. When correcting PT, CW and iEMG for CSA of m. quadriceps, such correlations were found only for Type IIA fibre area at 180° s~1. Elec- tromyographically, m. vastus lateralis (biopsied muscle) was representative for m. quadriceps. Calculated optimal mean power (CW s~1) and electrical efficacy (CW/iEMG) approximated for sprinters 450° s-1 and for marathon runners 270° s~1, i.e. velocities at or above the upper limit of the dynamometers. In orienteers, plantar flexor PT increased during winter training, but decreased during competitive season. Knee extensor PT increased over the whole year. At 30 and 60° s~1 only knee extensor PT was negatively associated with the running velocity at onset of blood lactate accumulation (VOBLA)- Changes in VOBLA during winter period were negatively associated with changes in knee extensor PT at 180° s~1. During competitive season, changes in Vobla were negatively associated with the ratio quality : quantity running. In ice hockey players PT varied non-systematically with training and games. The biopsy specimens of marathon runners showed irregular fibre shapes, an increased amount of connective tissue and central fibre nuclei, indicating an early strain disease or functional adaptation to extreme demands. During repetitive contractions in sprinters and marathon runners, fatigue, i.e. slope of decline in CW, was significantly associated with the Type II fibre area of m. vastus lateralis. For knee extensors of sprinters, ice hockey players and orienteers, a steep decrease in CW/iEMG was observed. In contrast, knee extensors of marathon runners and plantar flexors of orienteers showed an almost unaltered CW/iEMG throughout the test. The knee extensor endurance level (CW/iEMG) was significantly correlated to the maximal oxygen uptake. In orienteers, an increase in endurance level of both tested muscle groups during winter training parallelled an increase in VOBLA and V02obla- In hockey players, fatigue and endurance pattern (CW and CW/iEMG) changed non-systematically with training and games. In conclusion, isokinetic measurements and iEMG reflect the structural properties of the knee extensor muscles in sprinters and marathon runners. The demonstrated characteristics and changes in leg muscle function in different groups of athletes apparently reflect varying demands from different sports activities.S. 1-31: sammanfattning, s. 33-84: 6 uppsatser

Cette étude propose une approche centrée sur l’activité de l’élève telle que définie et expériencée en cours d’Education Physique et Sportive. Il s’agit d’accéder à ce qui fait sens pour lui/elle lorsque confronté à une situation de résolution de problème, étant entendu que la démarche menée est inductive, participante et internaliste. Le contexte de l’étude se place dans un cycle complet de Course d’Orientation (T = 16h de pratique effective ; 8 séances) mené par un enseignant expert de l’approche réflexive et de l’APSA, auprès d’une classe optionnaire de 19 élèves (âge moyen 17ans ½). Trois études sont menées afin de caractériser le fonctionnement des élèves confrontés à l’épreuve de Baccalauréat et à sa préparation. La première étude porte sur l’analyse de la performance à différents moments du cycle. La seconde étude porte sur les interactions entre profils moteurs, verbaux et réflexifs des élèves à partir des traces écrites de leur activité. La troisième étude s’intéresse, à partir d’un test ante/post cycle inspiré de la théorie des intelligences multiples de Gardner, à cerner l’évolution des capacités déclarées par les élèves. Les résultats montrent que les élèves voient leurs profils évoluer avec une réussite variable au cours du cycle ; ces profils s’expriment en contexte en fonction des situations d’apprentissage, des ressources mobilisées et de l’interprétation des relations carte/milieu naturel. Un suivi de cas permet d’individualiser les résultats qui viennent à la fois questionner la manière dont est abordée l’APSA Course d’Orientation et les stratégies complexes déployées par les élèvesThis study focuses on the student’s activity as defined and experienced in Physical Education. The target was to reach what makes sense for him/her when confronted with a problem solving task. The method used an inductive, participative and internalist approach. The study’s context was an optional full learning cycle of Orienteering (T= 16 hours duration; 8 sequences; n = 19 students 17 and half years old) taught by an expert teacher on critical thinking approach and on this sport practice. Three studies are expected to characterize the student functioning when confronted with the Baccalaureat examination and preparation. The first study layed on the analyzis of the performance at different moments of the learning. The second study was on the interactions between student motor, verbal and reflective profiles from the written reports of their activity. The third study was based on the pre/post test inspired from Gardner’ theory of the multiple intelligences: it helped describing the evolution of the declared capabilities of the students. Results showed that student profiles evolve according to a variable success all along the learning cycle; these profiles express within the situated context according to the learning tasks, the mobilized resources and the interpretation of the relationship between the map and the effective natural environment. A case study allowed individualizing the observations so as to question at a time the way Orienteering has to be taught and the complex strategies used by students
