Evaluating the Effects of Different Strength Training Techniques on Anthropometric Structure and Endurance of Healthy Quadriceps Femoris Muscle

This study was planned to examine the effect of superimposed, resistance exercise and electrical stimulation of the 3 different training on anthropometric characteristics and endurance of healthy quadriceps femoris muscle in untrained healthy young adults. Forty eight untrained healthy young subject aged between 21-26 (22.431.12) participated the study. Subjects were divided into 3 groups: Resistance Training Group (RTG) (n = 17); Electrical Stimulation Group (ESG) (n = 15) and Superimposed Training Group (STG) (n = 16). Dominant leg was determined by the selected tests and training was given three times a week for 6 weeks. Knee circumference, thigh circumference, skinfold measurements, repetition of 10-pound work, step-up, step-down an squatting on one leg test of subjects were taken pre-post training. The results indicated that electrical stimulation was not sufficient alone to strengthen the quadriceps femoris muscle. It is thought that training programs including voluntary muscle contraction must be main component of rehabilitation for muscle hypertrophy. In addition, resistance training has been effective in reducing adipose tissue.
