Materials and Methods: Forty students (20 males, 20 females) from the Department of Physical Education and Sports Science, University of Rajshahi, Bangladesh, were selected using stratified random sampling. Height and weight were measured to calculate BMI. BMR and body composition parameters, including intracellular water, extracellular water, total body water (TBW), fat mass, fat-free mass (FFM), and protein mass, were assessed using an IN-Body analyzer.

Results: Males had significantly higher BMR, TBW, and FFM than females (p<0.05). Pearson correlation analysis showed significant associations between BMR and TBW (males: r = 0.699, p = 0.001; females: r = 0.860, p < 0.001), BMR and fat mass (males: r = 0.678, p = 0.001; females: r = 0.476, p = 0.03), BMR and FFM (males: r = 0.610, p = 0.004; females: r = 0.493, p = 0.02), and BMR and protein mass (males: r = 0.642, p = 0.002; females: r = 0.668, p = 0.001). Moreover, BMR was associated with BMI in males (p=0.03) but not in females (p=0.76).

Conclusion: This study highlights the strong influence of body composition on BMR, with males exhibiting higher metabolic rates than females. These findings can aid in designing personalized health strategies to optimize metabolic health in university students.
