EFFECTIVENESS OF DIFFERENT INTENSITY OF RESISTANCE TRAINING: AN EMPIRICAL STUDY

Abstract

This study investigates the effectiveness of low, moderate and high intensity resistance training in improving back strength and strength endurance. Sixty female participants, with an Age: 18.54± 0.29, Height: 165.22 ±0.73, Weight: 62.26 ±1.18 and BMI 22.81±0.55 were randomly assigned to one of three groups: the Low Intensity Resistance Training Group (LIRTG), Medium Intensity Resistance Training Group (MIRTG), High Intensity Resistance Training Group (HIRTG) or the Control Group (CG). The training period was limited to three days per week for twelve weeks. Among the motor ability components back strength and strength endurance were selected as dependent variables. Back strength was measured by Dynamometer and  Strength Endurance was measured by Bent knee Sit-up Test. All the subjects were tested prior to and immediately after the experimental period on the selected dependent variable. The data obtained from the experimental groups and control group before and after the experimental period were statistically analyzed with dependent t-test and Analysis of covariance (ANCOVA). Whenever the ‘F’ ratio for adjusted posttest means was found to be significant, the Scheffe’s Post hoc test was applied to determine the paired mean differences. The level of confidence was fixed at 0.05 level for all the cases. In conclusion, the 12 weeks of the LIRTG, MIRTG and HIRTG programs effectively enhance back strength and strength endurance in college women athletes
