Abstract:

In response to Murray's 1982 suggestion of a standardised technique of measurement for warm-up decrement using orthogonal polynomial regression, a further modification is proposed, which places an emphasis on the analysis of performance rather than rate of change in performance scores.

Abstract:

The extent to which different mechanical baseball-batting devices used during a rest affected performance immediately after rest (warm-up decrement) was examined. Difference scores between the average of pre-rest Trials 8, 9, and 10 and each of 10 postrest trials were used to determine the presence of warm-up decrement. It was predicted that the use of a batting-T and the Batter's Aid machine (in which a batter swings ac a ball popped up within the strike zone) would result in superior performance measured as the distance (ft.) a ball was hit and frequency of contacts on postrest performance reducing or eliminating the warm-up decrement. Performance of 33 boys, aged 11 and 12 yr., indicated that only use of the Batter's Aid eliminated warm-up decrement with respect to both the distance and frequency as compared to the batting-T and control groups. In addition, the batting-T condition solicited significantly better performance than the controls on the distance measure but was statistically similar to the controls in frequency of contacts. Also, superior performance was significantly related to heightened heart rate, a physiological index of arousal. A primary explanation of the results focused on the effects of heightened physiological and psychological arousal on warm-up decrement.

Abstract:

Warm-up decrement and reminiscence effects have been primarily attributed to methods of distribution of practice. The present study investigated the effects of different amounts of practice on a balancing task and observed the differences in individual learning. Subjects were randomly assigned to a 5- or 10-trial practice group and performed a retention session on a stabilometer 1 wk. after the first set of trials. Subjects were given the same amount of rest between trials and sessions. Following the retention session subjects were assigned by retention performance into a warm-up decrement or reminiscence group for further comparison. The group with more practice had higher over-all performance. The warm-up decrement group showed more time-on-balance during the first practice session than the reminiscence group. The second session performance curves were nearly identical for the 5- and the 10-trial groups whether warm-up decrement or reminiscence occurred. These results suggested the importance of considering individual differences in retention of learning.

Abstract:

In the present study an attempt was made to determine the relative effectiveness of various warm-up activities in eliminating postrest warm-up decrement (WUD) in the tennis serve. Seventy highly-skilled players hit 20 serves, rested for either 5 or 15 min, and then attempted 4 final serves. During the last 2 min of the rest period, players continued to rest, ran in place, engaged in mental imagery, performed practice swings, or repeatedly hit the ball against the ground and caught it. In addition to estimates of serving accuracy, measures of somatic and cognitive arousal were obtained at the beginning and end of the rest interval. Multiple regression procedures revealed that reductions in WUD were significantly related to the restoration of prerest arousal levels. Between-group comparisons indicated that practice swings were the most effective warm-up activity for restoring somatic and cognitive arousal to prerest levels and for eliminating WUD. Theoretical discussion centered on possible applications of Nacson and Schmidt's (1971) activity-set hypothesis to the tennis serve.

Abstract:

The effect of asymmetry on flexibility and jump in taekwondo athletes and the influence of vibration foam rolling on asymmetry and frequency speed of kick test has not been examined. This study examined the effects of three warm-up protocols on subsequent sports performance in elite male taekwondo athletes. Fifteen elite male taekwondo athletes (20.63 ± 1.18 years) completed three warm-up protocols in a randomized order: general warm-up [GW], GW with vibration foam rolling [GW + VR], and GW with double VR for the weaker leg [GW + double VR]), was delivered before the subsequent tests: flexibility, single-leg countermovement jump (CMJ), 505 agility, hexagon test, and multiple frequency speed of kick tests (FSKTs). Relative to GW, the GW + VR significantly improved the hexagon test (GW + VR = 11.60 ± 1.01 s; GW = 12.80 ± 1.58 s). In addition, the GW + VR and GW + double VR yielded greater kick numbers in FSKT 5 (GW + VR = 21.13 ± 1.96 reps; GW + double VR = 20.93 ± 1.67 reps; GW = 19.27 ± 1.62 reps) and a higher kick decrement index (GW + VR = 5.45 ± 2.57%; GW + double VR = 5.88 ± 3.22%; GW = 9.54 ± 5.00%). However, the GW + VR and GW + double VR did not significantly improve the flexibility and CMJ asymmetry performance. The GW + VR is more beneficial for warming up than the GW is among male collegiate taekwondo athletes.

Abstract:

The aim of the study was to determine the performance indices of a repeated jumping test (RJT) over three different stages of a basketball game, and to examine their relationships with the aerobic capacity of young basketball players. Sixteen young (17.2 ± 0.4 yrs) trained basketball players performed an RJT (six sets of six consecutive vertical jumps) after warm-up, at halftime, and after completing a full game, as well as an aerobic power test (shuttle run test for 20m), each test taking place on a different day. Performance indices for each of the RJTs were the ideal jump height (IJ), the total jump height (TJ) of all the jumps, and the performance decrement (PD) throughout the tests. The IJ and TJ were significantly higher at the halftime compared with both after warm-up and after a full-time game (p<0.01). No major variations were noted in IJ and TJ in the full-time game compared to the warm-up. During any of the three game stages, there was no significant difference in the PD. No significant relationships were found between the aerobic capacity and any of the RJT performance indices at the different game stages. Given the present findings, coaches and players may consider the use of a more intense warm-up protocol, one that will efficiently prepare players for the early stages of a basketball game. The results also suggest that the aerobic energy system's involvement with repeated jumping activity is only minor when young players play basketball.

Abstract:

Team-sport athletes and coaches use varied strategies to enhance repeated-sprint ability (RSA). Aside from physical training, a well-conducted warm-up enhances RSA via increased oxidative metabolism. Strategies that impede blood flow could potentiate the effects of a warm-up due to their effects on the endothelial and metabolic functions. This study investigated whether performing a warm-up combined with blood-flow restriction (WFR) induces ergogenic changes in blood volume, muscle oxygenation, and RSA. In a pair-matched, single-blind, pre-post parallel group design, 15 American football players completed an RSA test (12 × 20 m, 20 s rest), preceded by WFR or a regular warm-up (SHAM). Pressure was applied on the athletes’ upper thighs for ≈15 min using elastic bands. Both legs were wrapped at a perceived pressure of 7 and 3 out of 10 in WFR and SHAM, respectively. Changes in gastrocnemius muscle oxygen saturation (SmO2) and total hemoglobin concentration ([THb]) were monitored with near-infrared spectroscopy. Cohen’s effect sizes (ES) were used to estimate the impact of WFR. WFR did not clearly alter best sprint time (ES −0.25), average speed (ES 0.25), total time (ES −0.12), and percent decrement score (ES 0.39). While WFR did not meaningfully alter average SmO2 and [THb], the intervention clearly increased the maximum [THb] and the minimum and maximum SmO2 during some of the 12 sprint/recovery periods (ES 0.34–1.43). Results indicate that WFR positively alters skeletal muscle hemodynamics during an RSA test. These physiological changes did not improve short-term RSA, but could be beneficial to players during longer activities such as games.

Abstract:

Purpose:To compare a novel sprint test on a cycle ergometer with a countermovement-jump (CMJ) test for monitoring neuromuscular fatigue after Australian rules football match play.Methods:Twelve elite under-18 Australian rules football players (mean ± SD age 17.5 ± 0.6 y, stature 184.7 ± 8.8 cm, body mass 75.3 ± 7.8 kg) from an Australian Football League club’s Academy program performed a short sprint test on a cycle ergometer along with a single CMJ test 1 h prematch and 1, 24, and 48 h postmatch. The cycle-ergometer sprint test involved a standardized warm-up, a maximal 6-s sprint, a 1-min active recovery, and a 2nd maximal 6-s sprint, with the highest power output of the 2 sprints recorded as peak power (PP).Results:There were small to moderate differences between postmatch changes in cycle-ergometer PP and CMJ PP at 1 (ES = 0.49), 24 (ES = –0.85), and 48 h postmatch (ES = 0.44). There was a substantial reduction in cycle-ergometer PP at 24 h postmatch (ES = –0.40) compared with 1 h prematch.Conclusions:The cycle-ergometer sprint test described in this study offers a novel method of neuromuscular-fatigue monitoring in team-sport athletes and specifically quantifies the concentric component of the fatigue-induced decrement of force production in muscle, which may be overlooked by a CMJ test.

Abstract:

The aim of this study was to assess the effects of different postactivation potentiation conditioning activities’ volumes and intensities on countermovement jump and multiple sets of high speed kicks. Nine taekwondo athletes (M±SD; age: 20.3±5.2 years; height: 177±7.2 cm; body mass: 71.8±15.3 kg; maximum dynamic half-squat 1RM: 132.8±32.5 kg and practice time: 9.6±7.2 years) participated. One control and four experimental conditions were randomly applied. Each condition was composed of warm-up, conditioning activity (half-squat: 1x3 at 50 or 90% 1RM or 3x3 at 50 or 90% 1RM), followed by a 10-minute rest interval, a countermovement jump and five sets of Frequency Speed of Kick Test. The conditions were compared using an analysis of variance with repeated measures, followed by Bonferroni post-hoc test. The alpha level was set at 5%. The significant difference was found in the number of kicks among sets (F3,21;128,36=25.34; p<.001; η2=.388 [small]). The rating of perceived exertion before control condition was higher than in all experimental protocols (F4,32=6.64; p=.001; η2=.454 [small]). There were no effects of volume and intensity on the variables investigated (maximum countermovement jump, mean countermovement jump, kick decrement, impact and rating of perceived exertion). Our results indicate that taekwondo athletes does not improve performance after conditioning activities of different volumes and intensities.

Abstract:

Abstract Context: Authors of most field studies have not observed decrements in physiologic function and performance with increases in dehydration, although authors of well-controlled laboratory studies have consistently reported this relationship. Investigators in these field studies did not control exercise intensity, a known modulator of body core temperature. Objective: To directly examine the effect of moderate water deficit on the physiologic responses to various exercise intensities in a warm outdoor setting. Design: Semirandomized, crossover design. Setting: Field setting. Patients or Other Participants: Seventeen distance runners (9 men, 8 women; age = 27 ± 7 years, height = 171 ± 9 cm, mass = 64.2 ± 9.0 kg, body fat = 14.6% ± 5.5%). Intervention(s): Participants completed four 12-km runs (consisting of three 4-km loops) in the heat (average wet bulb globe temperature = 26.5°C): (1) a hydrated, race trial (HYR), (2) a dehydrated, race trial (DYR), (3) a hydrated, submaximal trial (HYS), and (4) a dehydrated, submaximal trial (DYS). Main Outcome Measure(s): For DYR and DYS trials, dehydration was measured by body mass loss. In the submaximal trials, participants ran at a moderate pace that was matched by having them speed up or slow down based on pace feedback provided by researchers. Intestinal temperature was recorded using ingestible thermistors, and participants wore heart rate monitors to measure heart rate. Results: Body mass loss in relation to a 3-day baseline was greater for the DYR (−4.30% ± 1.25%) and DYS trials (−4.59% ± 1.32%) than for the HYR (−2.05% ± 1.09%) and HYS (−2.0% ± 1.24%) trials postrun (P < .001). Participants ran faster for the HYR (53.15 ± 6.05 minutes) than for the DYR (55.7 ± 7.45 minutes; P < .01), but speed was similar for HYS (59.57 ± 5.31 minutes) and DYS (59.44 ± 5.44 minutes; P > .05). Intestinal temperature immediately postrun was greater for DYR than for HYR (P < .05), the only significant difference. Intestinal temperature was greater for DYS than for HYS postloop 2, postrun, and at 10 and 20 minutes postrun (all: P < .001). Intestinal temperature and heart rate were 0.22°C and 6 beats/min higher, respectively, for every additional 1% body mass loss during the DYS trial compared with the HYS trial. Conclusions: A small decrement in hydration status impaired physiologic function and performance while trail running in the heat.

Abstract:

The aim of this study was to examine effects of cold-water immersion after exercise on powerresponses of wrestlers. Twenty elite male wrestlers were formed by similar age, height, weight and fitness parameters. The wrestling training session included a 60-minute of vigorous exercise. It consisted of warm-up exercises, standing technical and tactical exercises that mostly allocates arm and leg muscles. Vertical jump height, ropes climb height, and delayed onset of soreness was measured before, after, 24 h and 48 hors after the wrestling training. Cold-water immersion caused decrements in power loss at each follow-up time in comparison to a thermo neutral immersion. It can be suggested that the longer time needed for power to return to normal levels after cold treatment and assessment of varied contraction types may present a more broad demonstration of muscle function and consequential capacity for dynamic exercise following exercise-induced muscle damage.

Abstract:

Background: Perceived exertion is an acknowledged indicator of exercise intensity and homeostasis disturbance of an individual, however, there are few studies that have examined the influence of cold temperatures on perceived exertion measurements. Cognition is crucial to perception and exposure to cold temperatures can elicit decrements in cognition. Aims & Objectives: The aim of this study was to determine if, and to what extent, exposure to cold environments may influence perceived exertion and cognitive ability. Study Design: Randomised controlled trial. Materials & Methods: Sixteen participants (m= 8, f= 8, age: 22.3 ± 1.7 years (mean ± SD)), completed two trials in a randomised order in COLD (5°C) and CONTROL (18 °C, 55% relative humidity) conditions. During each trial, following a standardised warm up, participants performed a 6-minute cycle ergometer submaximal exercise. Cognitive ability was assessed pre and post exercise with a reaction time (RT) test. Participant’s physiological responses were measured using Rate of Perceived Exertion (RPE), Heart Rate (HR), Oxygen consumption (VO2), Minute Ventilation (VE), Tympanic (Tt) and Skin Temperature (Tsk) continuously during testing. Statistics: Two-way repeated measures Analysis of Variances (ANOVA), were between environmental conditions over time. Data are reported as mean (M) ± standard deviation (SD). Ordinal Friedman ANOVA tests were conducted on RPE data between environmental conditions and gender. Non-parametric descriptive statistics were reported as medians (Mdn) and inter-quartile ranges (IQR) (25th – 75th Percentile). Statistical significance was accepted at p < 0.05. Results: There was no significant difference (p > 0.05) reported in RPE, VO2 and VE between COLD and CONTROL groups, however, significant decreases in Tsk (p = 0.001) and Tt (p = 0.001) were observed in COLD compared to CONTROL groups. Additionally, no significant differences (p > 0.05) in RT occurred between COLD and CONTROL. Furthermore, no significant differences in RPE were established between genders. Conclusions: Short-term exposure to cold temperatures does not significantly affect physical exertion perception or cognitive ability.

Abstract:

The sympathetic and parasympathetic function of the Autonomic Nervous System[Formula: see text]ANS[Formula: see text] is the primary cause of the variations in Heart Rate and Skin Conductance[Formula: see text]SC[Formula: see text] during different physical activities. This paper aims to analyze the effect of different physical activities i.e. (a) Supine (b) Standing and (c) Warm-up, on Heart Rate Variability (HRV) and SC. The standard dataset of 18 subjects has been used to analyze the effect of physical activities on the HRV and SC. In the used dataset, the subjects are in supine, standing, and warm-up positions. The linear methods (time domain & frequency domain) of HRV are implemented on the standard dataset for analyzing the effect of physical activities. It has been observed with the analysis of the HRV that the mean value of time domain methods i.e. the NN interval’s standard deviation (SDNN), the successive RR interval’s root mean square (RMSSD), RR intervals with more than 50 ms differences in between them (NN50), percentage of successive RR intervals that have the difference of more than 50 ms (pNN50) are decreased and the value of Heart rate (HR) increased when the activity has been changed from supine to standing and standing to the warm-up positions. The value of frequency domain methods, such as low frequency (LF) and the ratio of low and high frequency (LF/HF) increased, while the value of HF decreases as activity changes from supine to standing and from supine to warm-up position. Further, the increment is also observed in the value of SC when activity is switched from supine to standing and from standing to the warm-up position. It is concluded from the results that there is a significant decrement that is observed in the value of HRV, while the increment is observed in the value of SC and HR. Decrement of HRV reflects that the sympathetic activity is increased as activity changed from supine to standing and further from standing to warm-up positions.

Abstract:

Although a 3- to 7-min re-warm up (RW) elicits performance and physiological benefits after half-time (HT), a time-efficient and feasible RW protocol is required for the use of an RW in the athletic setting. This study aimed to investigate the effect of a 1-min RW at high-intensity on the performance and physiological responses during the Loughborough Intermittent Shuttle Test (LIST). In a randomized and counterbalanced cross-over design, 12 male amateur intermittent team sports players (soccer, basketball, handball, and lacrosse; age, 22 ± 2 years; height, 1.70 ± 0.08 m; body mass, 65.1 ± 8.3 kg; body mass index, 22.4 ± 1.9 kg m−2; VO2max, 53.5 ± 4.5 ml kg−1 min−1) performed the LIST. The LIST comprised two 45-min halves separated by a 15-min HT. Each half comprised repetitions of exercise cycles consisting of 3 × 20-m walking, 1 × 20-m maximal sprint, 3 × 20-m jogging, and 3 × 20-m running. During the HT, the participants were assigned to a control trial (CON; 15-min seated rest) or an RW trial (1-min running at 90% of the maximal oxygen uptake after a 14-min seated rest). Compared to the CON, the RW prevents reductions in sprint performance at the fourth and sixth periods of the LIST (fourth: 2.4%, p = 0.002, d = 1.68, sixth: 3.6%, p = 0.012, d = 1.74) and a decrement of gastrointestinal temperature during HT (0.5°C, p = 0.010, d = 1.41). Moreover, the RW decreased the electromyogram amplitude of maximal voluntary contraction (MVC) after HT (12%, p = 0.017, d = 1.12) without a decrease of maximal voluntary contraction force, suggesting an increased neuromuscular efficiency (9%, p = 0.048, d = 0.58). The RW also increased the mean heart rate in the initial part of the second half (4 bpm, p = 0.016, d = 0.38). In conclusion, the RW improved sprint performance, core temperature, muscle activation, and heart rate in the second half of the LIST. The findings suggest that the RW should be recommended for intermittent team sports players when longer RWs are not possible.
