Purpose:to study the connection of psychophysiological characteristics with different levels of motivation in judo athletes of high qualification. Material:highly qualified athletes were examined, members of the National Judo Team (men). All athletes (n = 25) were divided into three groups, depending on the level of motivation to achieve success. Results:it is established that the high level of motivation for achieving success in judo is provided by activation of neurodynamic, cognitive functions and the level of light resistance. Athletes with a high level of motivation to achieve success is observed the predominance of the values of neurodynamic functions: endurance of the nervous system; speed of visual reactions. Athletes with an average level of motivation to achieve success identified higher values: productivity, speed, accuracy, effectiveness of verbal information. Athletes with a predominance of avoidance of failure motivation have a preference for other groups in the speed, efficiency and stability of the processes of thinking and processing information. Conclusions:judo athletes with a predominance of motivation to avoid a failure form coping strategy to prevent psycho-emotional stress. This helps to minimize the exhaustion of vegetative resources in conditions of extreme sports activity. Judo athletes with high level of motivation to achieve success, the presence of mental state of relative comfort is associated with the search for support among others and orientation toward internal beliefs.
Background To study the peculiarities of changes in creatinine concentration in blood serum of untrained men during the prolonged usage of training loads different in volume and intensity, and to determine the value of this biochemical marker for the assessment of adaptive body changes during fitness training. Methods We examined 50 untrained men aged 18–20 years who had no contraindications for practicing fitness. Taking into account the aim of the research, we divided these people into two groups: group A and group B. The research participants used training load regimes different in volume and intensity: representatives of group Aused low intensity training load regime (Ra = 0.53) and representatives of group B used high intensity training load regime (Ra = 0.72). To assess the adaptive body changes in the examined contingent, we used the anthropometry method (circumference body size) and bioimpedansometry (body composition indicators). We also determined the features of adaptation-compensatory body reactions to different training loads by means of biochemical control of creatinine concentration in blood serum. Results The obtained results showed a significant increase in basal level of creatinine concentration in blood serum (by 17.6%) of group B representatives fixed after 3 months of practicing fitness in high intensity training load regime (Ra = 0.72). This group representative also revealed the most pronounced manifestation of adaptive body changes confirmed by the results of the maximal muscle strength growth (1RM) and circumference body size, which was almost 2.5 times higher than the results of group A representatives for the same period of time. The parameters indicating the load volume in a set (Wn) were almost 62.0 % higher in group A representatives in comparison with group B during all stages of control. Nonetheless, the highest creatinine concentration in blood serum (by 11.1 % (p < 0.05) was fixed in group A representatives in response to training load after 3 months of practicing. This fact testifies to the important role of the creatine phosphokinase mechanism of energy supply of muscular activity in the conditions of high volume and low intensity training load regime (Ra = 0.53). Conclusion The analysis of the results obtained during a series of experimental studies indicates the need and feasibility of using the indicator of basal level of creatinine concentration in blood during fitness training, especially in the conditions of high intensity and low volume training load regime (Ra = 0.72), as an informative marker for assessing the process of long-term adaptation.
In the last decade Olympic sports are characterized by the presence of older athletes who have reached high athletic results. The purpose of the study was to research the age peculiarities of stress resistance and psycho-emotional states in elite wrestlers. A total of 19 elite athletes (a span of ages), all members of the Ukrainian National Team in Greco-Roman wrestling were examined. The perception and processing of visual information, the balance of the nervous system and psycho-emotional stability were studied. The deterioration of neurodynamic functions in emotionally stressful situations was more evident in older age group compared with the younger age group due to age weakening of the afferent system of information perception, analysis, and processing. Conclusion: The connection between the age of elite athletes and stress resistance to psycho-emotional tension was recorded. In particular, it demonstrated considerable changes in heart rate regulation in the older age group when compared with the younger age group where the optimal reaction of heart rate regulation to psycho emotional tension was observed. INTRODUCTIONIn last decade Olympic sports are characterized by the presence of older athletes who have reached high athletic results. The ages of champions and runners-up of International championships in some Olympic sports could be 36-42 years in individual sports and up to 52 in such sports as horseback riding and sailing. Extreme human activities and sports are connected with the presence of psycho-emotional factors which can influence the efficiency of sport results.(1,6,10).
Purpose: the aim of the work was to study the characteristics of vegetative regulation of cardiac rhythm in athletes of high qualification of different age groups. Material: 26 wrestlers of Greco-Roman style of high qualification aged 19-34 years old were studied. Vegetative regulation was assessed by statistical analysis of heart rate variability using cardiac monitors «Polar RS800CX». Results: the results showed that the wrestlers of older age group has a greater level of tension of regulation of heart rhythm for compared with young athletes. This is confirmed by the reduced values of the mean square deviation RR-intervals and triangular index. According to the results of spectral analysis of cardio revealed activation of parasympathetic tone of the autonomic regulation of the heart rhythm of wrestlers in older age group, compared with young athletes. The increase of tension of regulation of heart rate in the wrestlers of older age group accompanied by a slowdown of aperiodic and periodic oscillations of cardio intervals. Conclusions: the high level of tension of regulation of heart rhythm in older wrestlers group (26)(27)(28)(29)(30)(31)(32)(33)(34) accompanied by the activation of neurohumoral centers and parasympathetic link of vegetative nervous system. Key words: vegetative regulation of heart rate, wrestlers of high qualification, age groups, spectral analysis of cardio intervals.
