Background: The basal metabolic rate (BMR) measures the minimum amount of energy required to maintain physiological functions at rest. This study was conducted to examine the effects of a fitness-endurance program on basal metabolism and body composition of study population. Materials & Methods: This was a cross- sectional study conducted on 60 subjects (males-30, females-30). They were divided into 2 groups. Group I (30)(control) and group II (30)(study). Electrocardiogram (ECG) was done both at rest and with effort to assess cardiovascular parameters. Body composition was measured by DEXA scan. Basal metabolism rate was determined through indirect open circuit calorimetry, measured in laboratory standard conditions. Blood analysis was done in morning collection. T3, T4 analysis was done with competitive enzyme immunoassay and TSH with two-site immune enzymometric-assay. Results: The present study consisted of group I (control) and group II (study). Each group contains 15 males and 15 females. Variables such as age, height, body mass and BMI was compared in both the groups. No significant difference was found between both groups (P<0.05). The results of the body composition analysis was measured by DEXA in both the groups. Significant inter-group differences were observed in the variable total fat (%) in the pre- (p < 0.04) and post-intervention (p < 0.03) periods a. No significant alterations were observed in the other analyses. On comparing groups before and after the intervention period, we found a significant reduction in basal metabolism in both groups, with a significant inter-group difference in the post-intervention condition (p < 0.03). Comparison of T3 (ng/dl), T4 (ug/dl) and TSH (ulU/mL)in both groups. There was significant reduction in T3 and T4 in both groups (P<0.05). Conclusion: Aerobic exercise programme may alter the cardiovascular system and may not affect the basal metabolic rate in study population. However, large scale studies are required to substantiate the result obtained in this study.
