BW – body weight WHR – waist to hip ratio PBF – percent of body fat BMR – basal metabolic rate The impact of strength training on the changes in one’s physique and resting energy expenditure Background and Purpose: The aim of this research is to determine the way in which the strength training affects the changes in one’s physique and resting energy expenditure. Materials and Methods: 16 sedentary subjects completed strength training for seven weeks, 3 training/week. The examinee’s physique has been analyzed through bioelectrical impedance method (BIA) before and after the seven-week cycle. The variables compared are BW (body weight), WHR (waist-hip ratio), PBF (percent of body fat) and BMR (basal metabolic rate). The differences between the initial and final values have been tested by paired t-test. The correlations between those differences have been expressed by the Pearson correlation coefficient. The level of statistical significance is p=0, 05. Results: The results indicate that the strength training, even in rela-tively restricted time period, influences the changes in person’s physique, as well as the changes in resting energy expenditure. The mean difference for BMR (p=0.0036), WHR (p=0,022), PBF(p=0,0184) and BW (p=0.0275) have been established for the entire sample. For the males differences were found for BMR (p=0,002), PBF (p=0,0417) and BW (p=0.0280), but no significant change in WHR. No statistically significant changes were found in female group. Correlation was found for differences in results for BMR vs BW r=0.698 (p=0.003), BMR vs WHR r=-0.578 (p=0.019), and PBF vs WHR r=0,671 (p=0,004). Conclusions: The overall changes in one’s physique and energy expen-diture indicate that the strength training needs to be one of the crucial factors in physical activity, aimed at the improvement of person’s health
