Aerobic and Strength Training With Caloric Restriction on Insulin Resistance in Obese Premenopausal Women

Study Overview
=================
Brief Summary
-----------------
A total of 42 premenopausal women diagnosed clinically as having insulin resistance. Their ages ranged from 35 to 45 years old; their body mass index was >30 kg/m2 and They were obese women complained of insulin resistance and non diabetic or cardiovascular disease, were randomly assigned to group A participated in aerobic & resistive exercise program, and group B participated in aerobic exercise and followed prescribed diet restriction program. Both of the groups (A&B) followed the treatment program 3 times per weeks for 8 weeks. Assessment of the fasting glucose, fasting insulin, and HOMA test of insulin resistance were measured for all subjects in both groups (A and B) was carried out before and after the end of the treatment program

Detailed Description
-----------------
Forty two obese premenopausal women diagnosed as having insulin resistance were participated in this study. They were selected randomly from the out Patient Clinic of Obstetrics at Kasr El Ainy University Hospital, Faculty of Medicine, Cairo University. Their age ranged from 35 - 45years, their body mass (BMI) were>30kg/m2. Exclusion criteria of the study were as follows: Patients having diabetic or cardiovascular disease, Patients with life threatening disorders as renal failure and myocardial infarction, Patients with active malignancy and patients with severe hemorrhage, hyperthyroidism, acute viral diseases and mental disorders. Participants were assigned randomly used sealed envelope into two groups (A&B) equally in number. Group (A): (Combined resistive and aerobic exercise group) consisted of 20 women were participated in aerobic & resistive exercise program plus diet restriction, 3 times per weeks for 8 weeks. Group (B): consisted of 20 women were participated in aerobic exercise plus diet restriction 3 times per weeks for 8 weeks.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: were randomly assigned to group A participated in aerobic and resistive exercise program, and group B participated in aerobic exercise and followed prescribed diet restriction program. Both of the groups (A&B) followed the treatment program 3 times per weeks for 8 weeks. Assessment of the fasting glucose, fasting insulin, and HOMA test of insulin resistance were measured for all subjects in both groups (A and B) was carried out before and after the end of the treatment program.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: aerobic exercise<br>walking on treadmill | Other: Resistance exercise<br>* Resistance exercise were performed for all participants in group (A) only included 9 exercise for big muscles of upper limbs (shoulder flexors muscles, shoulder extensors and shoulder abductors), lower limbs (hip flexors, hip extensors and knee flexors and knee extensors) and abdominal muscle using moderate work load (60 - 75% of IRM) 1set of 10 repetitions, progressing to 2 sets of 10 repetitions after four weeks for 20 minutes<br>Other: Aerobic exercise<br>* aerobic exercise were performed on treadmill. For 20 minutes. All patients in both groups (A,B) had attended the program of a resistance exercises and followed by aerobic exercise for 8 weeks in form of 20 minutes walking on the treadmill without inclination.<br>* Other names: exercise;Dietary Supplement: diet restriction<br>* All participants in both groups (A,B) were instructed to follow a moderate restricted diet limited to (1800-2000) kcal/ day under supervision of a certified dietician. The diet contained: Protein and fibers: 20% carbohydrate: 50-60%, fat: low 20%.<br>|
