Comparative analysis of the effects of two different training protocols on strength development and body composition for muscle mass gain and fat-burning goalscomparative analysis of the effects of two different training protocols on strength development and body composition for muscle mass gain and fat-burning goals

Aim: This study aims to examine the effects of two different training protocols aimed at muscle mass gain and fat loss on strength development and body composition. Methods: This study began with a total of 36 male participants and was completed with 27 participants (14 in the fat loss group and 13 in the muscle mass gain group). The groups performed a total of 40 training programs including resistance exercises using different loading and resting methods over a period of 14-16 weeks. Anthropometric data such as height, weight, shoulder circumference, chest circumference, waist circumference, hip circumference, and arm circumference were collected using standardized protocols. Body fat percentage measurements were performed using a bioelectrical impedance analysis device. Muscle strength was measured using specific exercises including Bench Press, Lat Pulldown, Squat, Military Shoulder Press, Barbell Curl, and Triceps Push Down. Maximum strength (1RM) for each exercise was recorded at the beginning, middle (after the 8th and 24th workouts), and end (after the 40th workout) of the training intervention. Results: The findings of this study indicate that the fat loss-focused training program significantly reduced body fat percentage while also supporting some strength gains. The muscle mass gain-focused training program was more effective in promoting strength development and muscle mass gain, while also contributing to a slight reduction in body fat percentage. Conclusion: In conclusion, this study confirmed that customization of training protocols according to individual goals would be beneficial for optimal results. Future research should include a multidisciplinary approach by incorporating nutrition and recovery strategies to further examine these effects.
