Влияние физической нагрузки на частоту сердечных сокращений у студентов‑медиков

The aim of the study was to analyze the dynamics of heart rate (HR) changes in medical students under standardized moderate physical activity and to evaluate the recovery rate. Thirty students (15 males, 15 females) aged 18-23 were examined. HR was measured at rest, immediately after 1 -minute squats, and after 5 minutes of rest. A significant HR increase after exercise (72 ± 8 bpm -> 125 ± 10 bpm; p < 0.001) and partial recovery (85 ± 7 bpm; p < 0.05) was observed. Recovery speed correlated with physical activity level (r = -0.62; p < 0.01). This test may serve as a screening tool for cardiovascular fitness.
