The aim of conducted research was an attempt to define the dynamics of aerobic and anaerobic endurance changes in the short track female competitors training during a year cycle which is dependent on the energy characteristic of training burden. Nineteen female competitors of OMKŁS Opole club and KU AZS PO Opole, were put through the examination. Eight of them were members of National Team and Olympic Team (Vancouver 2010), moreover, the competitors participated in the World Cup, World Championship, European Championship. The other examined competitors were members of National Team. With the help of terrain and laboratory tests, an official record was made on every lap time, final time of every trial, HR max and HR medium as well as the concentration of lactate in blood in fourth minute after an effort. In the thirtieth minute, after an effort, HR and lactate concentration were registered in order to define the course of restitution. Anaerobic and mixed parameters were examined by the Wingate test in 7.5% load formula of body weight. The results of researches proved that a selection of applied training burdens was not conductive to the adaptation of process according to the Mathews, Fox model (1976). In the short track, a training burden should reflect the specific of an effort in this discipline, emphasising an anaerobic energy type in a year cycle of preparations.

Background: The purpose of the study was to investigate whether, in addition to an expected increase in anaerobic endurance, aerobic endurance of disabled swimmers would also improve in a special preparation sub-period. Furthermore, decision was made to examine whether the applied tests prove sufficiently sensitive for swimmers with disabilities as well. Material/Methods: The study included 12 disabled swimmers from a section of the Polish Sports Association for the Disabled “START” Wroclaw. Two standardized tests were used. The T- 30 test was used to evaluate aerobic endurance and the 6x50 m test was applied to estimate anaerobic endurance. For all analyzed parameters the median, first (Q1) and third (Q3) quartiles were calculated. To determine the significance of differences between the results obtained in the preliminary and the control test, the nonparametric Wilcoxon test for dependent samples was used. Statistical significance was considered at p ≤ 0.05. Results: Total distance median in the T-30 test (DST1 = 1575.5 m vs DST2 = 1650 m) improved in a statistically significant way (p = 0.02). Analyzing the results obtained in the entire group of athletes in the 6x50 m test, for each single section of 50 m, it was observed that the swimming time was significantly shorter during the second study (p < 0.05) but the first section of 50 meters. Conclusions: In a sub-period of special preparation both aerobic and anaerobic endurance of disabled swimmers improved. A more significant improvement was observed in terms of anaerobic endurance, as it occurred for all swimmers. The T-30 and 6x50 m tests proved to be a sensitive tool for assessing aerobic and anaerobic endurance of swimmers with disabilities.

Purpose. The aim of this study was to derive the regression equation for predicting VO2max of athletes by the relatively new submaximal 3'Bike Test. Methods. This test was conducted on 1501 active football male players, aged 16÷35 years. A medical anamnesis was administered and then the athletes’ weight was measured. Afterwards, the athletes performed the 3'Bike Test followed by the Astrand Bike Test for comparison reasons. Results. Linear regression of the data indicated that the produced regression model, as a whole, is statistically significant. In addition, the system of predictive variables was able to explain for 48% of total variability of the criterion variable VO2maxAST. According to the regression coefficients that had been derived, a regression equation that could predict VO2max was created. A significant high correlation (r = 0.688) and a non-significant paired t-test (p = 0.782) found between the measured VO2max (Astrand test) and the predicted VO2max (3'Bike Test) indicates a large similarity between the predicted and measured VO2max values. Conclusions. The 3'Bike Test was found to be a capable measurement tool of aerobic endurance, more reliable and valid than the Astrand submaximal test, as well as being shorter, more easily executed and a better predictor of VO2max.

The purpose of this study was to establish the anthropometric and physical profiles of elite young soccer players according to their playing position, and to determine their relevance for the selection process. One hundred and fifty-six young male soccer players participated in the study. Players were classified into the following groups: Goalkeepers (n=16), Central Defenders (n=26), External Defenders (n=29), Central Midfielders (n=34), External Midfielders (n=28), and Forwards (n=23). Anthropometric variables of participants (body height, body mass, body mass index, 6 skinfolds, 4 diameters, and 3 perimeters) were measured. Participants performed the Yo-Yo test, sprint tests (30 m flat sprint and Balsom agility test) and 2 jump tests (countermovement jump and the Abalakov test). At the end of the season, the technical staff of the club selected some of the players to continue playing on the same team and the rest were not selected. The results show that heavier and taller outfield players performed better in vertical jumps and sprint tests, whereas leaner outfield players performed better in the Yo-Yo test. Fat percentage of selected players was lower than that of the non-selected ones. The rest of the body components were similar in the selected and non-selected players within each playing position. Moreover, the selected players performed slightly better than the non-selected players in the physical test, but these differences were not statistically significant.
