Sixty patients who have partial thickness burn with burned body surface area (BBSA) about 30% to 50% will participate in this study after their release from intensive care unit. Their ages will be ranged from 20 to 45 years. The participants will be selected from Orabi hospital and randomly distributed into two equal groups.~1. Group A (Study group): This group includes 30 burned patients who will receive resistance exercises 8 weeks (3times/week) by using dumbbells and sand bags in addition to their physical therapy program (splinting, stretching ex. and ROM ex.) and medical treatment.~1. Group B (Control group): This group includes 30 burned patients who will receive their physical therapy program (splinting, stretching ex., strengthening ex. and ROM ex.) and medical treatment.
Resistance training will be performed for 8 weeks with thrice-weekly sessions on non-consecutive days. The program will consist of seven exercises: triceps press, biceps curl, lat pull-down, calf raise, leg press, leg extension and sit-ups using dumbbells and sandbags. Each session will last approximately 45 minutes and consist of a 5-minute warm-up with stretching followed by a resistance exercise that will be done as a circuit, ending with a 5-minute cooldown. The 1 repetition maximum (1RM) is measured at baseline and following the intervention. Initially, participants will do two circuits using 50% of their 1RM and repeat them 10 times for the first and second weeks, progressing to two circuits, using 60% of their 1RM and repeating 10 times for the third and fourth weeks. In the fifth and sixth weeks, participants will do three circuits using 60% of their 1RM and repeat 10 times. In the last two weeks, patients will do three circuits using 70% of their 1RM and repeat 10 times. A 90-second rest will be allowed between sets of exercises (Hallsworth et al., 2011).
