【摘要】：目的观察不同强度游泳对成年代谢综合征(MS)患者安静时心率变异性(HRV)的影响。方法选取成年MS患者126例,根据入组先后顺序分为低强度组、中强度组及高强度组,各42例。各组均进行为期4周不同强度的游泳运动,检测并比较运动前后HRV指标。结果 (1)各组LF运动后即刻降低,在恢复期30 min内缓慢上升,高强度组上升的最明显(P0.05)。低强度组HF运动后即刻上升,中强度组和高强度组运动后即刻降低(P0.05);(2)各组SDNN运动后即刻下降,在恢复期30 min内缓慢上升,但比较差异无统计学意义(P0.05)。各组RMSSD运动后即刻上升,在恢复期30 min内缓慢降低(P0.05)。各组PNN50运动后即刻下降,在恢复期30 min内中强度组和高强度组缓慢上升,而低强度组持续下降(P0.05);(3)中强度组和高强度组运动后LF、HF、SDN N、R MSSD及PN N 50较运动前升高,LF/HF较运动前降低,且与低强度组比较,差异均有统计学意义(P0.05或P0.01)。结论 4周中强度和高强度的游泳运动可以改善MS成人患者的HRV,而低强度的游泳运动对HRV影响不明显。
[Abstract]:Objective to observe the effect of swimming with different intensities on HRV in patients with adult metabolic syndrome (MS) at rest. Methods 126 adult MS patients were selected and divided into low intensity group, middle intensity group and high intensity group according to the order of entry. 42 cases of each group were treated with swimming exercise for 4 weeks with different intensity. The HRV indexes before and after exercise were detected and compared. Results: the HRV decreased immediately after LF exercise in each group, and increased slowly within 30 min of recovery period. In the low intensity group, HF increased immediately after exercise, while in the moderate and high intensity groups, the level of SDNN decreased immediately after exercise (P 0.05), and increased slowly within 30 min of recovery period. However, the difference was not statistically significant (P 0.05). RMSSD increased immediately after exercise in each group, and decreased slowly within 30 min of convalescence. PNN50 decreased immediately after exercise in each group, and increased slowly in medium intensity group and high intensity group within 30 min during recovery period. However, the low intensity group continued to decrease P0.05 (P < 0.05). After exercise, the low intensity group and the high intensity group had lower MSSD and PN N50 levels than those before exercise, and compared with the low intensity group, compared with the low intensity group, the FLF / HF was lower than that before exercise, and compared with the low intensity group. Conclusion moderate and high intensity swimming exercise at 4 weeks can improve HRV in adult patients with MS, but low intensity swimming exercise has no significant effect on HRV.
