A comparative study on level of sports confidence between team game and individual game athletes

endurance and cardiorespiratory fitness. On the other hand, HRV can be measured using both time and frequency domain parameters and it refers to the variation between consecutive heartbeats. It is influenced by the interplay between the sympathetic and parasympathetic branches of the autonomic nervous system, which regulate heart rate. Both VO2 max and HRV provide insights into aerobic fitness, they capture different aspects of it. VO2 max focuses on the body’s ability to utilize oxygen during exercise, primarily reflecting aerobic capacity, while HRV reflects the variability and balance of the autonomic nervous system, providing information about its regulation and overall cardiovascular health. This study aimed to see the influence of aerobic fitness on selected HRV indices in regular exercisers.
