A Study of Long-term Taijiquan Exercise on Skeletal Muscle Mass and Muscle Strength in Elderly Individuals
This study aimed to investigate the influence of long-term Taijiquan exercise on skeletal muscle mass and muscle strength in older individuals,as well as the differences between sexes.94 elderly individuals were recruited in the community by preaching.48(male:24,female:24)with more than 5 years of Taijiquan exercise experience were the experimental group.46 subjects(male:23,female:23)with irregular physical exercise experience were the control group.The skeletal muscle mass and muscle strength were tested by body composition analyzer,dynamometer and muscle function analyzer respectively,which parameters were analyzed by two-factor variance statistics(gender+Taijiquan exercise).The results showed that regardless of gender,the older individuals who long-term Taijiquan exercise had high skeletal muscle mass than that control group,and there were significant differences in relative appendicular skeletal muscle mass RASM and skeletal muscle index SMI(P＜0.05).In addition,the experimental group had higher squatting strength than the control group,with significant differences(P＜0.05).Regardless of whether Taijiquan exercise was performed,there were significant differences in skeletal muscle content and strength between genders(P＜0.01).This suggests that long-term Taijiquan exercise can effectively delay skeletal muscle mass decline and lower limb muscle strength in older individuals,though there is no clear effect on upper limb grip strength.This indicates that seniors should increase their intensity of resistance training during physical exercise.
