    Opis:
    Objectives: The objective of this work was to determine the dynamics of maximal anaerobic power (MAP) of the lower limbs, following a single whole body cryostimulation treatment (WBC), in relation to the temperature of thigh muscles. Materials and Methods: The subjects included 15 men and 15 women with an average age (±SD) of 21.6±1.2 years. To evaluate the level of anaerobic power, the Wingate test was applied. The subjects were submitted to 6 WBC treatments at -130°C once a day. After each session they performed a single Wingate test in the 15, 30, 45, 60, 75 and 90th min after leaving the cryogenic chamber. The order of the test was randomized. All Wingate tests were preceded by an evaluation of thigh surface temperature with the use of a thermovisual camera. Results: The average thigh surface temperature $(\text{T}_\text{av})$ in both men and women dropped significantly after the whole body cryostimulation treatment, and next increased gradually. In women $\text{T}_\text{av}$ remained decreased for 75 min, whereas in men it did not return to the basal level until 90th min. A statistically insignificant decrease in MAP was observed in women after WBC. On the contrary, a non-significant increase in MAP was observed in men. The course of changes in MAP following the treatment was similar in both sexes to the changes in thigh surface temperature, with the exception of the period between 15th and 30th min. The shorter time to obtain MAP was observed in women till 90th min and in men till 45 min after WBC compared to the initial level. Conclusions: A single whole body cryostimulation may have a minor influence on short-term physical performance of supramaximal intensity, but it leads to improvement of velocity during the start as evidenced by shorter time required to obtain MAP.

    Opis:
    The selection into the National Hockey League (NHL) is based on criteria reflecting job analysis of a professional ice hockey player and the requirements of the game. Only few Czech elite ice hockey players succeed to participate in NHL and their number is decreasing in the last decade. Aim of Study: The aim of the study was to find out and evaluate the level of anaerobic readiness of Czech hockey forwards and defenders playing in the NHL and to compare their anaerobic performance with that in elite national hockey players from the Czech extra-league. Material and Methods: Results of 30s Wingate anaerobic test obtained in 26 forwards and 16 defenders, Czech hockey players from the NHL (from 2001/2002 to 2015/2016 seasons) were compared with the reference values of elite Czech ice hockey players. The comparison was based on the mean values, rate of dispersion, and effect sizes were calculated using Cohen's d coefficient. Results: In forwards, both absolute and relative values of peak power (PP) and anaerobic capacity (AnC) found in Czech players in NHL were higher (d>1) than in elite Czech national players. In defenders, only the value of AnC relative to body mass showed small effect (d=0.36), but absolute and relative values of PP and absolute value of AnC were higher (d>1) than in elite Czech national players. Conclusion: The results of the study indicate that anaerobic readiness evaluated by 30s Wingate test may be, besides dominant on-ice skills, one of the criteria for entry to the top ice hockey competition.

    Opis:
    Objectives: The aim of this study was to compare the influence of creatine monohydrate and creatine malate supplementation on aerobic and anaerobic capacity in semi-professional soccer players during preparation period. Methods: 15 adult soccer players from polish second league club took part in the study. Participants were divided into two groups (Group 1: supplemented their diet with creatine monohydrate; group 2: used creatine malate). Before and after five-week preparations the aerobic (PWC 170 test) and anaerobic (Wingate test) capacity of the players were measured. Findings: Significant increase in PWC 170 indicator, maximal oxygen uptake, and total work capacity in Wingate test were noted in the group that consumed creatine monohydrate. Moreover, two-way ANOVA results showed significant effect for time in above mentioned variables. Conclusions: Creatine monohydrate supplementation may efficiently support aerobic and anaerobic capacity development in semi-professional soccer players. Five-week creatine malate supplementation provides no significant changes in aerobic and anaerobic capacity.

    Opis:
    Introduction: This study's purpose was to measure and compare isokinetic muscle function and anaerobic exercise capacity of knee joints according to the three Kukki Taekwondo competition types. Methods: A total of 21 elite Korean male poomsae (forms), gyorugi (sparring), and demonstration athletes majoring in Taekwondo were selected as the subjects of the study. Subjects' physical fitness levels were measured using standardized strength, endurance, agility, balance, and flexibility tests. In particular, the isokinetic muscle function measurement system was used to measure the muscle function of subjects' knee joints, and the Wingate test was used to measure their anaerobic exercise ability. Results: Gyorugi athletes showed better results than their poomsae and demonstration counterparts in nearly all metrics, including body composition, physical fitness factors, isokinetic muscle function (60°/sec), muscle power (180°/sec), and anaerobic exercise capacity. Gyorugi athletes were also taller and showed higher muscle mass, strength, muscular endurance, and agility. However, poomsae athletes showed a higher level of flexibility. The results found isokinetic muscle function and anaerobic exercise capacity of the knee joint to be most important for gyorugi athletes and then for demonstration and poomsae athletes, in that order. Conclusions: This study provides useful information needed to identify the physical fitness factors of the different Kukki Taekwondo athletes, and, in turn, it is may serve as important fundamental data for developing future systematic Taekwondo training programs.
