Introduction. An underweight individual are very lean, has very thin muscles and concerned about increasing weight and fitness level. Resistance training relates to an extensive activity leading to muscle contractions as a response to resistance to an external force. Resistance training (RT) Improves athletic performance in various sports and also maintains quality of life (Behringer, & et al, 2010). The purpose of this study was to find out the impact of low, medium and high intensity of resistance training on some selected fitness variables and muscular hypertrophy among underweight males. Method. A group of (N=40) subjects was selected randomly to participate in this study. The age of the underweight participants was in the range of 18-24 years, resistance training program was employed for 12 weeks, two days in a week, 45 minutes of training per session. These participants were segregated into two groups namely Group-A (N=20, experimental group), Group -B (N=20 control group). The resistance training was employed on experimental group. Control group was not given any above mentioned special training program. The pre and posttest considered for the selected some fitness variables and test as follows; body composition (BMI), muscular power (standing long jump), speed (30.M sprint) and balance (standing on one leg test), for muscular hypertrophy (waist and hip ratio). To compare the mean differences from pre to post test, percentages with the help of calculator online, mean, standard deviation, and t-test was computed by the help of SPSS software. Result and Discussion. The twelve weeks of training protocol had revealed significant performance from pre to posttest among the underweight males with regard to the selected fitness variables and muscular hypertrophy and presented by percentages i.e. BMI (increased by 3.49%), standing long jump (increased by 23.53%), 30. M Sprint economy (increased by 12.29%), standing on one leg test (increased by 83.87%), waist - hip ratio circumference (increased by 20.78%). The control group had not shown any changes pertaining to the selected fitness variables and muscular hypertrophy from pre to post test. Conclusion. It is concluded that the impact of resistance training from pre to posttest had shown significant performance among the underweight males with regard to the selected fitness variables and muscular hypertrophy i.e. Body mass index, muscular power, speed, balance and waist-hip ratio. Lastly Control group had not shown any changes from pre to post test. [ABSTRACT FROM AUTHOR] |
