- Group A (combined intervention group: n=30): will perform supervised resistance exercise training three times per week and follow a high-protein diet (1.3 g protein/kg/day)
- Group B (control group: n=30): will receive a high-protein diet and general health advices and be asked to maintain their usual lifestyle. They will be offered the intervention post-study.

The training started with a 10-min warming up followed by two sets of 50 s of the following exercises: leg press, knee extensions, leg curls, chest press, seated row, plantar flexion, and sit-to-stand exercises. During the 12-week period the number of sets was gradually increased from 2 - 3 set for all exercises, the time to perform the exercises increased from 50 - 75 s, and resistance was increased by using dumbbells, elastic bands, medicine balls and a step bench. The training ended with 5-min cooling down. Attendance to the training sessions was recorded.
Dietary intervention:
- Protein intake: 1.3 grams of protein per kilogram of body weight per day.
- Distribution: protein intake will be evenly distributed across meals (≥ 30g per meal).
- Monitoring: participants will keep 3-day dietary records every two weeks. Group B (control group): will receive high protein plan and a single session of general advices on the importance of physical activity based on national guidelines. They will be contacted every two weeks for general check-ins to maintain engagement but will not receive structured exercise or dietary planning.
