Added effects of circuit resistance training with treadmill training on cardio-pulmonary endurance in young obese individuals

Abstract

AIM: To study the effect of treadmill training combined with circuit resistance training (CRT) and treadmill training alone on cardio-pulmonary endurance in young obese individuals. OBJECTIVES: 1) To study the effect of treadmill training on cardio-pulmonary endurance in young obese individuals.2) To determine the additional effects of CRT on cardio-pulmonary endurance in young obese individuals and compare it with aerobic training alone. METHODOLOGY: 30 young individuals, both male and female, with BMI> 25 kg/m2, were included in the study. They were randomly divided into two groups A and B. Group A performed treadmill training thrice a week, for 20 minutes for four weeks duration at an intensity decided by heart rate reserve calculated by Karvonen's formula. Group B performed ten minutes of treadmill training followed by 30 minutes of circuit resistance training consisting of exercises like leg curls, leg extension, leg press, abdominal curls, lateral pull-down, triceps push away, biceps curls. The intensity of these exercises was 50% of 1 RM and 30 seconds at each station. The VO2 max was determined pre and post four weeks using Queen's College step test, and body weight was also recorded pre and post four weeks. RESULT: Wilcoxon Signed Rank test was used to analyze the two outcome measures result within the group pre-post values. The P-value for Vo2 max for both group A and B was <0.05. The same was the p-value for body weight. Mann-Whitney Rank Sum Test was used for the between-group analysis of VO2 max and body weight, and the p-value was <0.05. All these p values were statistically significant. CONCLUSION: From this study, we concluded that a training program consisting of treadmill training and circuit resistance training has a positive effect on cardiopulmonary endurance.
