Effects of Endurance and Strength Training and Their Combined Intervention on Body Composition of High School Students

Abstract

OBJECTIVETo compare the effects of endurance and strength training and their combination on the body composition of high school students.METHODSSubjects (n=125) were randomized into endurance training (E), strength training (S), combined strength and endurance training (SE), or control group(C) for 18 weeks, 3 times/week, for 25 min. Bioelectrical impedance analysis were perform before and after training.RESULTSBody weight, BMI (Body Mass Index), body fat, body fat rate and muscle mass significantly decreased in E (both P<0.01). Body weight, BMI, body fat and muscle mass significantly increased in S (both P < 0.01), body fat rate increased significantly (P<0.05). Body fat, body fat rate and muscle mass significantly decreased in SE (P < 0.01). Body fat rate decreased significantly in C (P < 0.01).CONCLUSIONEndurance training led to decrease in body weight, BMI, body fat, body fat rate and muscle mass. Strength training led to increase in body weight, BMI, body fat, body fat rate and muscle mass. Strength and endurance combination training led to decrease in body fat, body fat rate and muscle mass.Support or Funding InformationThe key lab of adolescent health intervention and exercise assessment
