Resistance Training with Low to High Intensity Protocol on Muscular Hypertrophy, and Selected Health Related Fitness Variables among Overweight Males

Introduction: Right intensity of resistance training schedule is very important for improving health and performance among overweight males. Overweight condition is a big threat around the world and leads to many health hazards. Maintaining one's bodyweight ideal the following three things are important i.e. diet, exercise and lifestyle. The purpose of this investigation is to find out the influence of resistance training with low to high intensity protocol on selected health related fitness variables and muscular hypertrophy among overweight males from pre to post test. Method: A group of (N=100) participants were selected randomly to participate in this study. The age of the overweight males was in the range of 18-24 years, resistance training program was applied for 12 weeks, 45 minutes of training per session and two days in a week. These participants were segregated into two groups namely Group-A (N=50, experimental group), Group - B (N=50 control group). The resistance training was employed on experimental group. Control group was not given any above mentioned special training program. The pre and post-test considered for the selected health related fitness variables and test as follows; body composition (BMI), muscular strength (bench press 1RM), muscular endurance (sit-ups test for 30 sec), flexibility (sit & reach test) and cardiovascular endurance (12 minutes run / walk test). And test for muscular hypertrophy i.e. (participants' girth of neck, shoulders, chest, arms, waist, hips, thigh and calf). To compare the mean differences from pre to post test, mean, standard deviation, and t-test was computed by the help of SPSS-16 software and the percentages were calculated with the help of calculator online. Result and Discussion: Twelve weeks of resistance training protocol had shown significant performance from pre to post-test among the overweight males with regard to the selected health related fitness components and presented by percentages i.e. BMI (0.453%), bench press (40.33%), sit-up test (15.93%), sit & reach test (31.08%), and 12 min run/walk test (28.21%). Furthermore the muscular hypertrophy is enhance among the male participants i.e. neck (0.97%), shoulder (5.04%), chest (5.34%), arms (11.57%), thigh (9.01%), calve (3.12%); and lastly waist (-1.95%), and hip (1.76%) had shown reduction in circumference respectively from pre to post test. Conclusion: It is concluded that the impact of resistance training with low to high training protocol had shown significant performance among the overweight males with regard to the health related fitness variable i.e. (BMI), bench press, sit-up test, sit & reach test and 12 min run & walk test. As per the percentages it is concluded that the muscular hypertrophy of the overweight males i.e. neck, shoulder, chest, arms, thighs, and calves circumference had shown increased in the muscular size. Lastly the participants had shown reduction in waistline and hip circumference from pre to post test.
