Effects of Weight Training and Circuit Weight Training on Selected Strength and Physiological Variables

Abstract: 
The purpose of the present study was to find out the effect of weight training and circuit weight training on
strength and physiological variables among male players of various games and sports. For this purpose, forty five male players studying in various colleges around Thiruvallur, Tamilnadu, were selected as subjects. The age of the subjects ranged from 18 to 23 years. They were divided into three equal groups, each group consisted of fifteen subjects, in which experimental group – I underwent weight training, experimental group – II underwent circuit weight training and group -III acted as control who did not participate in any special activities apart from their regular activities. The training period for the present study was three days (alternative days) in a week for twelve weeks. Prior to and after the experimental period, the subjects were tested on leg strength, strength endurance and vital capacity. Leg strength was assessed by administering dynamometer in kilograms, strength endurance was assessed by administering sit-ups test in numbers per minute and vital capacity was analysed by using wet spirometer in liters. The Analysis of Covariance (ANCOVA) was applied to find out any significant difference between the experimental groups and control group on selected criterion variables. Whenever the adjusted post-test mean was found to be significant, the Scheffé S was used as post-hoc test. The result of the study shows that the weight training and circuit weight training groups were increased the leg strength,strength endurance and vital capacity significantly (P > .05). It was concluded from the results of the study that weight training and circuit weight training has brought positive changes in leg strength, strength endurance and vital capacity as compared to the control groups. It was concluded that no significant difference was found between the weight training group and circuit weight training group on selected criterion variables.
