Conditions

Sarcopenia. Activities involving other muscle strengthening exercises

Interventions

Intervention 1: Intervention group 1: Resistance training plus high protein diet (1.6 g/kg/day). In this group, participants will train for 3 sessions per week for 8 weeks. It should be noted that res

on the second visit, blood draw (after 48 hours of rest and 8 overnight sleep), and body composition will be performed

on the third visit, maximal strength (1RM) and endurance (75% 1-RM) will be assessed

on the fourth visit, participants will complete muscular power tests using Wingate tests. After completing the pre-test process, the participants will be visited by a nutritionist and will be informed
