Abstract |
INTRODUCTION The purpose of this study was to investigate the body composition, muscle strength and hormone after 10 weeks of resistance training According to gender. METHOD Seventeen young men(n=9) and women(n=8) completed 10 weeks of heavy-resistance training with large muscle 4 days/week. RESULT After 10 weeks of resistance training, body weight, BMI, muscle mass, and body fat increased in men. However, body weight, BMI, and body fat decreased and muscle mass increased in women. Growth hormone and Insulin level significantly increased for both men and women. Absolute strength of shoulder press, lat pull down, biceps curl and strength per lean body mass showed the differences between genders before resistance training and increased in both men and women after resistance training. Absolute strength of squat, leg extension, and leg curl showed the differences between genders before resistance training and increased in both men and women after resistance training. Leg extension and leg curl per lean body mass showed the differences between genders before resistance training but squat per lean body mass didn't showed the difference between genders before resistance training.
CONCLUSION We concluded that muscle mass, upper and lower muscle strength significantly increased and body fat decreased for both men and women after 10 weeks of resistance training. Absolute gains in muscle strength in response to heavy-resistance training typically were more in men than in women. Relative the changes of muscle strength per lean body mass increments after resistance training, however, may be more in women than in men. Therefore, no gender differences were observed in the changes of muscle strength and anabolic hormone after heavy resistance training, indicating that the differences of relative change were not found in both men and in women. |
