摘要
目的:评估大强度的无氧间歇练习、有氧耐力练习及其组合练习的次序对恢复期心脏自主神经功能的影响。方法:采用随机交互设计,15名健康男性受试者分别完成4次运动:600 m间歇跑练习、30 min大强度持续跑练习、600 m间歇跑加30 min大强度持续跑练习,30 min大强度持续跑加600 m间歇跑练习,分别在运动前(0~10 min)、整个运动期间和运动后恢复期(0~20 min)记录RR间期,并进行相应HRV分析以及在运动前和运动后即刻进行血乳酸测试。结果:与安静状态相比,运动中HR、EPOC和TRIMP均显著增加,但组合练习次序间不存在显著差异;恢复期20 min内,HR随恢复时间增加逐渐降低,但同一恢复阶段不同运动方案之间无显著差异;RMSSD、SDNN、SDNN/HR、HF和LF变化相似,在整个恢复阶段均显著低于安静值,但HF和LF在恢复期(15~20 min)显著增加;而LF/HF随着恢复时间延长显著增加。结论:大强度的无氧间歇练习、持续有氧练习及其组合练习,在运动后早期恢复阶段(0~20 min)HRV变化趋于一致,提示耐力运动后心脏自主神经功能的调整可能不具有运动形式依赖性。此外,大强度无氧间歇和有氧耐力练习的组合练习次序不影响运动后恢复期心脏自主功能的调节,恢复期20 min内,交感活性仍处于较高水平。
Objective： This test is to evaluate the effects of high intensity anaerobic interval exercise,aerobic endurance Exercise and combined exercise order on the cardiac autonomic function in recovery period. Method： In a random cross-over design, 15 healthy young males performed four exercises： 600 m anaerobic interval exercise, 30 min high intensity continuous exercise, 600 m anaerobic interval exercise plus 30 min high intensity continuous exercise, 30 min high intensity continuous exercise plus 600 m anaerobic interval exercise. The R-R intervals was recorded, including pre-exercise（0-10 min）, the whole exercise period and recovery stage（0-20 min）. HRV analysis was made and lactic acid tests were arranged before and immediately after the exercises. Result： HR, EPOC and TRIMP for all the exercises significantly increased compared to rest, and there was no significant difference between the combined exercises. During the 20 min recovery, as the recovery time increased, HR tended to decrease, but there was no significant difference between the different exercises at the same recovery stage. The changes were similar for RMSSD, SDNN, SDNN/HR, HF andLF, which were lower than those at rest. However, HF and LF significantly increased during15-20 min of the recovery time, and as the recovery time increased, LF/HF tended to increase significantly. Conclusion： The changes of HRV are nearly the same at the early recovery stage（0-20 min）after high intensity anaerobic interval exercise, aerobic endurance exercise and combined exercise.This suggests that the regulation of cardiac autonomic function does not depend on exercise types after endurance exercise. Besides, the combined exercise order of high intensity anaerobic interval exercise and aerobic endurance exercise does not affect the regulation of cardiac autonomic function at the recovery stage. Within 20 min in the recovery period, sympathetic activities remain higher.
