摘要：Esco MR, Williford HN. Cardiovascular Autonomic Modulation in Collegiate Male Basketball Players. JEPonline 2011;14(1):35-42. The purpose of this study was to investigate cardiovascular-autonomic modulation in collegiate male basketball players by comparison to physically fit, non-athletic controls. Short-term resting heart rate variability (HRV) and heart rate recovery following maximal treadmill exercise (HRR) was examined across two groups as follows: 17 male collegiate basketball (B) players (21.5 ± 2.2 years, 188.9 ± 4.5 cm, 85.3 ± 9.7 kg, 46.2 ± 6.9 ml. kg-1.min-1 ); and 17 college-age male controls (C) (21.8 ± 2.1 years, 184.2 ± 3.2 cm, 84.3 ± 9.7, 46.1 ± 6.8 ml. kg-1.min-1 ). The following frequency domain parameters of HRV were recorded: normalized high frequency power (HFnu), and low frequency to high frequency power ratio (LF:HF). Heart rate recovery was recorded at 1- (HRR1) and 2- (HRR2) minutes during a cool-down period. The statistical findings showed that the B group had significantly higher HFnu (48.5 ± 14.6 ms2 for B versus 34.2 ± 14.8 ms2 for C, p < 0.05), HRR1 (20.7 ± 6.1 beats.min-1 for B versus 16.5 ± 5.6 beats.min-1 for C, p < 0.05), HRR2 (HRR2 = 44.1 ± 10.3 beats.min-1 for B versus 36.4 ± 9.0 beats.min-1 for C, p < 0.05) and significantly lower LF:HF (1.1 ± 0.6 for B versus 2.4 ± 1.0 for C, p < 0.01), compared to the C group. The results indicate a superior cardiovascular-autonomic profile in basketball players, which could be a potential mechanism to explain the decreased cardiovascular disease risks in these athletes. Thus, participation in competitive basketball could possibly improve cardiovascular autonomic modulation.
