Resistance Training in Patients With Morbid Obesity

The 20-week RT program will consist of three sessions per week, each lasting for 1 hour that will be applied to both control obese (CG) and morbid obese (MO) group. All sessions will start with 15 minutes warm-up with continuous walking and joint mobility and flexibility exercises, 5 minutes of cool down and stretching, in order for preventing injuries. Sessions will include 4 to 8 RT exercises targeting different muscle groups; 1. forearm, 2. knee flexors and 3. extensors, 3. trunk, 4. chest, 5. shoulder elevators, 6. horizontal shoulder flexors and 7. extensors, and 8. plantar flexors. The exercises for each muscle group will be performed in 3 sets of as many repetitions (continuous concentric/eccentric voluntary contraction) possible in 1 minute followed by 2.0 minutes of passive recovery. Before the RT program, each participant will be measure using the subjective modified Borg scale (1-10 points), in order of identifying the muscle failure into 1 minute of exercise.
