Opis:: Trampoline flight time is a recent addition to Olympic scoring and was sufficient in weight to displace a formed medal winner from a podium placement at the 2012 Olympics. The aim of our study was to examine different warm-up routines on trampoline flight time. We examined ten elite, female trampolinists (mean ± SD: age 19.2 ±5.4 y) who performed six different warm-up routines in a randomised, cross-over, counter-balanced manner: (a) static stretching (STAT, control), (b) STAT+10 trampoline bounces, (c) dynamic stretching (DYN), (d) DYN+10 trampoline bounces, (e) DYN+Drop jumps (DYN+DJ) and (f) DYN+isometric mid-thigh pulls (DYN+IP). Data were analysed using general linear models, Dunnett-HSU post-hoc tests vs. Control/STAT and magnitude based inferences vs. control. Our analysis demonstrated that total flight time following DYN 10 (17.29 ±0.52s, 83% likely beneficial, P < 0.002) was significantly longer versus STAT (16.59 ±0.49 s), with a trend toward significance for DYN (16.97 ±0.20 s; 22% likely beneficial, P = 0.077). The DYN-IP (14.04 ± 0.48 s) and DYN-DJ (14.15 ±0.66 s) produced the shortest vs. all warm-up forms (P < 0.005). To the contrary, the DYN+DJ and DYN+IP conditions were >99% likely to be detrimental to performance. Our results demonstrate a clear improvement in flight times when using a dynamic warm-up coupled with a trampoline specific bouncing task (DYN+10).

"1000m maximal test"
Opis:: Introduction. The purpose of this study was to evaluate the time of covering a distance of 1000 m on a rowing ergometer by competitors of the Academic Sports Association of the Pomeranian Medical University and to relate the achieved results to the best results from the Polish Rowing Ergometer Academic Championships. Methods. 28 rowers were tested in the 1000 m "maximum" test (1000TM/t). In addition, correlations were sought between the time and power values obtained in the 1000 TM/t with the values of selected anthropometric indices (height and weight, body mass index BMI), hand grip strength, heart rate and body composition components (free fat mass FFM, skeletal muscle mass SMM). Results. The significant correlation between the time and power output in 1000TM/t and values of FFM, SMM, handgrip strength test as well as resting HR have been observed. Conclusion. The results obtained at 1000TM/t can be considered promising for the further training stage due to the fact that the study was conducted on a rowing ergometer under training conditions prior to a special training mesocycle shaping strength and speed, while the athletes competing at the event to which our results were related were in peak competitive performance.

Opis:: The purpose of this study was to assess the effects of three different warm-up condi-tions on a 5K cycling time trial (TT). Sixteen trained cyclists completed the study. At the first testing session, participants completed a maximal graded exercise test to assess maximal oxygen consumption (VO2max) and a familiarization of the TT. At three subse-quent visits, the participants completed the TT after no warm up, short warm-up of three minutes at 60% VO2max, or long warm-up of ten minutes at 60% VO2max. The warm-up was assigned in randomized order. VO2, heart rate (HR), lactate, power, and speed were assessed after the warm-up, 1K, and completion of the 5K TT. There was no dif-ference between type of warm-up for time, power, cadence, speed, VO2, HR, or lactate levels at the end of the TT. There was no significant difference between type of warm-up for time, VO2 or HR at the end of the 1K split. Warm-up length was not impactful on 5K TT performance or during the first km of the TT in trained cyclists. These results con-flict with previous evidence indicating that a warm-up in endurance events primarily improved VO2 kinetics at the onset of the exercise.

Tematy:: sustained attention

Opis:: One of the important aspects of attentional processes in sport performance is sustained attention during task execution. The objective of this study was to analyze the ability to maintain attention during a serial reaction time task performance in expert handball players (n = 12) and non-athletes (n = 12). Participants p erform a FitLight TrainerTM (Fitlight Sports Corp., Canada) test protocol configured by the PDA controller which consisted of 10 series of simple motor reaction task to visual stimuli appearing on 8 wireless light discs. Each of the 10 series included 22 reactions. Ability to maintain attention was determined by analyzing the variability in results during testing, e.g. the total time of test execution and the average reaction time to visual stimulus in each subsequent series. The main finding in our study was that Non-athletes in comparison to Athletes had: (1) longer total time of test execution; (2) longer reaction time; (3) and higher variability in results during task performance. The results indicate a higher level of ability to maintain attention in handball players.

Tytuł:: The importance of Reaction Time in Athletics: Influence on the Results of Sprint Runs of World Championships Finalists

reaction time
Opis:: In athletic sprint disciplines, the segments of start and start acceleration occupy an important place that significantly generates the final outcome of the race. The question is to what extent the start time of the reaction (latent time) has a contribution to achieving the results of sprint disciplines. The aim of the current research was to determine the influence and connection between the reaction time and the result performance of running in the disciplines of 100 m, 200 m, 400 m finalists of ten world championships. The results of a total of 456 finalists (231 men) and 225 (women) competitors who competed in the final races of the championships (from Edmonton, 2001 to Doha, 2019) were analyzed. The evaluation of the start reaction time and sprint results was based on reports officially published by the International Association of Athletics Federation (IAAF). Central and dispersion parameters were calculated for all variables. The relationship between reaction time and sprint results was calculated using the Pearson correlation coefficient, and simple regression analysis determined the direct influence of reaction time on the result success and calculated the relevant coefficients for the level of statistical significance p < 0.05. Based on the obtained results, a positive but low correlation was recorded between the mean values of the 100 m sprint results and the reaction time in men (r = 0.230p < 0.044), which was also confirmed by regression analysis. In other correlations and values of regression coefficients, no significant numerical values of the influence of reaction time on the result success were recorded in both categories of finalists.
