줄넘기 운동이 사무직 근로자의 신체조성, 근피로도 및 건강관련 체력에 미치는 영향

Abstract

Purpose: The purpose of this study is to determine the effects of jump rope exercise on body composition, muscle fatigue and physical fitness in white-collar workers. Method: Twenty white-collar workers (n=20) were randomly assigned to jump rope exercise group (JEG, n = 10) and control group (CON, n = 10). Jump rope exercise was performed for 48 minutes, 3 times a week, and for 6 weeks. The body composition (weight, muscle mass, body fat and BMI), muscle fatigue (tibialis anterior muscle, rectus abdominis muscle, erector spinae muscle and gastrocnemius muscle) and Physical fitness (one leg standing with closed eyes, sit-up, sit-reach, plank, grip strength and harvard step) were measured before and after 6-week jump rope exercise. Results: Muscle fatigue of erector spinae muscle had statistically significant interactions between T (p=.013) and G×T (p=.011) respectively. In physical fitness, sit-up significantly increased at JEG (p=.038) after jump rope exercise than that before. Plank and Harvard step showed statistically significant interactions in G×T (p=.049, p=.011) respectively. Conclusion: These results suggest that jump rope exercise improve muscle fatigue and physical fitness in white-collar workers.
