Analysis and assessment of athletes' adaptation potential are important components of effective selection and prediction of sports successfulness. Purpose: study and analysis of kick boxers' cardio-vascular system's adaptation potentials under standard physical load and in recreation. Material: in the research kick boxers (n=17, students) participated. The athletes were divided into 2 groups, depending on reaction to physical load: 1st group-athletes with normotonic type of reaction (n=9, age 17.56±0.80 years); 2nd group-athletes with reaction different from normotonic (n=8, age18.25±0.88 years). Indicators of cardio-vascular reaction type and tolerance to physical load were found with the help of PWC170 test. Results: we confirmed similarity of kick boxers' reaction to physical load. After 1st stage of physical load heart beats rate was noticeably lower in the 1st group. After 2nd stage of load systolic blood pressure was lower in the 1st group. After load, in the 1st group heart beats rate and systolic BP restored quicker. Reduction of heart beats rate under load in 1st group can serve as a proof of better adaptation mechanisms. Conclusions: training of athletes with periodic control of electric cardiogram under physical loads permits to assess functional state of cardio-vascular system; its adaptation and correspondence to definite physical loads. Such approach permits not to admit progressing of cardio-vascular system's pathological state.

Purpose:comparative analysis of limbs' joints goniometric indicators of martial arts athletes; study of sportsmanship level influence on kick boxers' movements' amplitude. Material:martial arts athletes -students and senior pupils (n=29) participated in the research. The participants were divided into two groups. 1 st group consisted of 18 kick boxers of age 17.44±0.34 years. 2 nd group included 11 wrestlers of age 18.45±0.39 years. The first group was divided into two sub-groups: sub group 1a -9 athletes of age 18.22±0.52 years and sportsmanship level: candidates and masters of sports. Sub group 1b consisted of 9 athletes, age (16.67±0.24) years and sportsmanship level from beginners to 1 st sport category. We registered movements' amplitude in wrist, shoulder, elbow, hip, knee and ankle joints. Results:we confirmed the distinctions of goniometric indicators of martial arts athletes' limbs joints. It was found that sportsmanship level of kick-boxers influences to certain extent on movements' amplitude. The found distinctions reflect clearly specific of kind of sports. Wrestlers have higher amplitude of movements in wrist joints that determines reliable grip in a fight. Kick boxers have better amplitude of movements in elbow and shoulder joints. It permits to punch with higher strength. The closeness of goniometric indicators of different sportsmanship kick-boxers proves equal orientation of their training. Need in constant keeping combat stance conditions reduction of in-movement amplitude in right wrist joint and outside movement in left shoulder joint of experienced athletes. Conclusions:increase of abduction in hip joint and reduction of bending in left knee joint illustrate specificities of punching/ kicking, optimization of their technique in experienced athletes. The higher is training experience, the more working asymmetry of joints' movements is.

Objective Betaine supplementation may enhance body composition outcomes when supplemented chronically during an exercise program. The purpose of this study was to evaluate the effect of betaine supplementation on development-related hormones, body composition, and anthropometrics in professional youth soccer players during a competitive season. Methods Twenty-nine players (age, 15.45 ± 0.25 years) were matched based upon position and then randomly assigned to a betaine group (2 g/day; n = 14, BG) or placebo group (PG, n = 15). All subjects participated in team practices, conditioning, and games. If a subject did not participate in a game, a conditioning protocol was used to ensure workload was standardized throughout the 14-week season. Growth hormone (GH), insulin-like growth factor-1 (IGF-1), testosterone, cortisol, height, weight, and body composition were assessed at pre-season (P1), mid-season (P2) and post-season (P3). Anthropometric variables were also measured following a one-year follow-up (F). Results Significant (p < 0.05) group x time interactions were found for testosterone and testosterone to cortisol ratio (T/C). Both variables were greater in BG at P2 and P3 compared to P1, however, the testosterone was less in the PG at P3 compared to P2. There was no significant group by time interactions for GH, IGF-1, lean body mass, or body fat. There was a significant (p < 0.05) group x time interaction in height and weight at F, with the greater increases in BG compared to PG. Conclusion Betaine supplementation increased testosterone levels and T/C ratio in youth professional soccer players during a competitive season. Betaine supplementation had no negative effects on growth (height and weight) and may attenuate reductions in testosterone due to intense training during puberty.
