摘要
To observe the effect of age on the changes in heart rate variability (HRV) of adult amateur athletes after playing a soccer game, 20 male were divided into two groups: middle-aged (n = 10, 35-55 years) and aged (n = 10, 56-75 years). Before and after 2-hour soccer games, HRV and blood pressure were recorded. In both groups heart rate increased greatly after exercise (73.1 /- 14.8 bpm vs 102.6 /- 16.2 bpm, p 0.01 and 71.1 /- 8.6 bpm vs 89.9 /- 15.5 bpm, p 0.01). In the middle-aged group, systolic blood pressure (SBP) did not change (124.0 /- 12.0 mmHg vs 118.9 /- 11.7 mmHg), while the mean standard deviation of the N-N intervals (SDNN), square root of the mean squared differences of successive N-N intervals (RMSSD), total power (TP), low frequency (LF) power, and high frequency (HF) power changed significantly (p 0.05); in the aged group SBP decreased from 147.2 /- 23.7 mmHg to 127.7 /- 24.7 mmHg (p 0.01), but SDNN, RMSSD, TP, LF, and HF did not change. It seems that in aged people the accommodation capability of the autonomic nervous system is different from that in middle-aged people.
