Outcome Measures
Primary Outcomes (1)
Muscle Strength
Maximal voluntary strength of major muscle groups (upper and lower extremity) will be measured using 1-repetition maximum (1RM) tests for biceps curl, squat, and bench press. The heaviest weight that can be lifted once with proper form is recorded. Higher values indicate greater muscle strength.
8 weeks

Free Weight Resistance Exercise Group
EXPERIMENTALMachine-Based Resistance Exercise Group
EXPERIMENTALInterventions
Participants will perform supervised resistance exercises using weight machines (including machine-based biceps curl, squat, and bench press) at an intensity of 60-80% of one-repetition maximum (1RM), 2 sets of 8-12 repetitions, 3 times per week for 8 weeks.
Participants will perform supervised resistance exercises using free weights (dumbbells and barbell), including biceps curl, squat, and bench press, at an intensity of 60-80% of one-repetition maximum (1RM), 2 sets of 8-12 repetitions, 3 times per week for 8 weeks.
