摘要
目的:通过将血流限制与低强度有氧运动相结合,并与传统有氧运动方式、高强度间歇运动方式进行对比,探讨不同运动方案下受试者的急性生理反应与疲劳程度的差异,旨在为大众人群或运动员提供一种更加安全、高效提升有氧能力的训练方法。方法:招募12名男性大学生,在完成最大摄氧量测试后,随机完成四种运动方案,分别为40%VO_(2peak)低强度有氧运动(AE)、50%动脉闭塞压(AOP)结合40%VO_(2peak)低强度有氧运动、70%AOP结合40%VO_(2peak)低强度有氧运动和HIIT四种方案,每种方案运动时间为15 min。记录受试者运动前、运动中和运动后的生理反应(心率、摄氧量、气体交换率、血乳酸)[HR、VO_(2)、RER、BLA]和主观疲劳度(RPE)。通过双因素重复测量方差分析方法(组×时间)对受试者的HR、VO2、BLA和RPE等指标的变化情况进行统计分析。结果:HR:50%AOP组、70%AOP组和HIIT组分别在第9 min、第6 min和第3 min显著高于AE组(P<0.05);VO_(2):HIIT组在3 min显著高于AE组(P<0.05),50%AOP组、70%AOP组与AE组无显著性差异(P>0.05);RER:50%AOP组、70%AOP组和HIIT组分别在6 min、6~9和15 min、3~15 min显著高于AE组,70%AOP和HIIT组之间没有显著性变化;BLA:HIIT组运动后峰值显著高于AE组、50%AOP组和70%AOP组(P<0.05)。RPE:AE组、50%AOP组、70%AOP组和HIIT组均随时间显著上升(P<0.05),但无显著性差异(P>0.05)。结论:血流阻断结合低强度有氧运动可以在不增加主观疲劳度的基础上,显著提高受试者的急性生理反应,其效果要优于普通有氧运动。
This study aimed to compare acute physiological responses and RPE levels among participants in different exercise protocols involving varying degrees of blood flow restriction(BFR)combined with low-intensity aerobic exercise,traditional low-intensity aerobic exercise,and high-intensity interval training(HIIT).The goal was to provide a safer and more efficient aerobic training method for both the general population and athletes.Twelve male university students completed maximal oxygen consumption(VO_(2peak))testing and randomly engaged in four 15-minute exercise protocols of 40%VO_(2peak)low-intensity aerobic exercise(AE),50%blood flow restriction pressure(AOP)combined with 40%VO_(2peak)low-intensity aerobic exercise,70%AOP combined with 40%VO_(2peak)low-intensity aerobic exercise,and HIIT.Physiological responses(heart rate,oxygen consumption,respiratory exchange ratio,blood lactate)and perceived fatigue(Rating of Perceived Exertion,RPE)were recorded before,during,and after exercise.The results showed that 50%AOP,70%AOP,and HIIT groups had significantly higher HR than AE at the 9th,6th,and 3rd minutes,respectively(P<0.05).VO 2:HIIT had significantly higher VO_(2)than AE at the 3rd minute(P<0.05).RER:50%AOP,70%AOP and HIIT were significantly higher than AE at 6th min,6~9th and 15th min,3~15th min,respectively(P<0.05),while no significantly difference between 70%AOP and HIIT.BLA:HIIT's post-exercise peak BLA was significantly higher than AE,50%AOP,and 70%AOP(P<0.05).RPE increased significantly over time in all groups(P<0.05)with no significant differences between groups(P>0.05).The present study indicated that blood flow restriction combined with low-intensity aerobic exercise increased acute physiological responses without significantly increasing RPE.However,exercise effectiveness did not increase with higher levels of blood flow restriction.Achieving a higher aerobic exercise physiological responses may require moderate blood flow restriction combined with a higher exercise intensity.
