Background & Study Aim: Regular game of tennis positively affects cardiorespiratory and musculoskeletal systems, brain, helps to normalize body weight, develops dexterity, speed and endurance. Objective of the study was knowledge about the influence of recreational exercises with tennis components on functional state and physical fitness of mature men, aged 40-49.
Material & Methods: The sample consisted of 60 men: the experimental group (30 people aged 45 ±2.98 years); the control group (30 people aged 45 ±2.90 years). Two pedagogical tests were conducted before and after the experiment for men in the experimental and control groups. The functional state of the group under study was assessed seven times based on the analysis of heart rate variability (HRV) indicators.
Results: A cycle of recreational exercises with tennis components has been developed for men, aged 40-49, residing in the Republic of Sakha (Yakutia). The analysis of intergroup differences in HRV indicators after the experiment showed positive changes in the cardiovascular system in the experimental group members. All 16 studied indicators of HRV changed after one year of the experiment, which indicates a statistically significant improvement in the indicators of the physiological state (p<0.05). There was a significant decrease of the following indicators in comparison with the control group: stress index changed by 108.3%, LF/HF – by 101%, the indicator of activity of regulatory systems – by 231%, as well as an increase in HF (higher frequency of HRV) by 73% (p<0.01). In addition, throughout the experiment the experimental group showed positive dynamics of composite indices of heart rate regulation, myocardial and psychoemotional state, with a range of growth from 13% to 19%. There was an improvement in all tests of general and special physical fitness. The performance test figures for speed and dexterity significantly differ than those of the control group. The control group showed a proved improvement in the strength of the upper shoulder girdle muscles (p<0.05).
Conclusions: The positive influence of recreational exercises with tennis components on indicators of functional state, body weight, body mass index, as well as physical fitness of mature men, aged 40-49, residing in the Republic of Sakha (Yakutia) was revealed. They showed a decrease in the tension of regulatory systems, a decrease in humoral and metabolic effects on the heart rate regulation, and the economization of the cardiovascular system.
