Investigating the Effect of Physical Training on Heart Rate Variability in Universit Male Players

This study aimed to assess the impact of physical training on heart rate variability (HRV) in male university ergo rowing athletes and middle- and long-distance track and field athletes. Ninety athletes, aged 19 to 25, underwent an intensive 8-week training program. HRV measurements were taken at baseline, after 4 weeks, and at the end of the 8 weeks using a Polar H10 strap. Results showed significant decreases in HRV across all sports: ergo rowing saw a 60% decrease, middle-distance events a 61% decrease, and long-distance events a 75% decrease from pre- to post-intervention. These reductions indicate a high physiological response to intensive exercise, suggesting that structured training positively affects autonomic function and cardiovascular health. The findings highlight the importance of physical training in maintaining autonomic balance and overall cardiovascular health in athletes.
