摘要
目的:对比高强度间歇训练(High-intensity interval training,HIIT)运动处方对肥胖大学生的影响。方法:共招募63名肥胖大学生,年龄为(21.6±2.1)岁,BMI为(25.6±1.7),随机分配至跑台HIIT组(n=21)、轻力量HIIT组(n=21)和无训练对照组(n=21)。跑台组进行跑步变速HIIT,轻力量组进行徒手抗阻HIIT,对照组除学校体育课外不进行额外的运动训练。12周干预前后,分别测量受试者的健康体适能指标。结果:跑台HIIT运动处方和轻力量HIIT运动处方使肥胖大学生的体重、BMI、体脂率和体脂肪含量显著降低(P<0.05),握力和VO_(2)max显著上升(P<0.05),但只有跑台组的内脏脂肪面积显著减少(P<0.05)。结论:HIIT运动处方能有效提升肥胖大学生健康体适能。跑步HIIT运动处方对内脏脂肪的减少更有效,而轻力量HIIT运动处方在力量素质的提高上更有优势。建议肥胖大学生采用轻力量HIIT运动处方,以获得更大的健康收益。
Objective:To compare the effects of High-intensity interval training(HIIT)exercise prescriptions on obese college students.Methods:A total of 63 obese college students(21.6±2.1 years old)with BMI(25.6±1.7)were recruited and randomly assigned to treadmill HIIT group(n=21),light strength HIIT group(n=21)and control group without training(n=21).The treadmill group received variable speed HIIT,the light strength group received HIIT,and the control group received no additional exercise training except school sports.The physical fitness indexes of the subjects were measured before and after the 12-week intervention.Results:The body weight,BMI,body fat percentage and body fat content of obese college students were significantly reduced by treadmill HIIT and light strength HIIT(P<0.05),and the grip strength and VO_(2)max were significantly increased(P<0.05).Only the visceral fat area of the treadmill group was significantly decreased(P<0.05).Conclusion:HIIT exercise prescription can effectively improve the fitness of obese college students.Running HIIT exercise prescription is more effective in reducing visceral fat,while light strength HIIT exercise prescription is more advantageous in improving strength quality.It is suggested that obese college students adopt the exercise prescription of light strength HIIT to achieve greater health benefits.
