短期加压力量训练对成年男性身体成分及心血管功能的影响

Effects of Short-Term KAATSU Training on Body Composition and Cardiovascular Function in Male Adults

目的:观察短期抗阻结合加压力量训练对成年男性身体成分和心血管机能产生的具体影响。方法:招募22名无任何专业运动项目和力量训练背景的成年男性作为受试者,先通过一次性实验确定短期加压力量训练方法,再测定两周抗阻结合加压力量训练前后部分受试者身体成分及心血管机能的变化情况。结果:250 mmHg为加压力量训练的最佳压力设置值;两周训练后,250 mmHg加压组受试者的下肢骨骼肌含量、左心室射血分数、心输出量明显增长(P<0.05);但对照组与实验组受试者在下肢围度、身体成分、血糖血脂及其他心脏功能指标方面却均未出现明显变化(P>0.05)。结论:短期加压力量训练能够使成年男性的骨骼肌含量增加、在一定程度上改变身体成分,同时还会使成年男性安静状态下的左心室射血分数和心输出量有所提升。

Objective:The purpose of this study was to investigate the effects of short-term KAATSU training on cardiovascular function and body composition in male adults.Methods:Twenty-two male adults without any professional sports experience were included in study,the KAATSU training method was determined based on a one-time experiment;and before and after two-week KAATSU training,their body composition and cardiovascular function changes were measured.Results:The 250 mmHg was the best pressure setting value for KAATSU training.After two-week 250 mmHg KAATSU training,the lower limbs muscle mass,left ventricular ejection fraction(LVEF)and cardiac output(CO)of the experimental group were higher than before(P<0.05);there were no significant changes of lower limb circumference,body composition,blood glucose,blood lipid and other cardiac function indexes in both control group and experimental group(P>0.05).Conclusion:Short-term KAATSU training could significantly increase muscle mass and change body composition to some extent,and also promote LVEF and CO of male adults at rest.
