Background and Aim: One of the consequences of obesity is coronary artery disease (CAD) and diabetes. Effective exercise programs for patients with the coronary artery disease is a strategy for decreasing obesity and is expected to help in eventually limiting obesity-associated long-term health. The purpose of this study was to compare the effectiveness of a physiotherapy and exercise based cardiac rehabilitation  on the anthropometric measurements of obesity in the diabetic and non diabetic men.

Materials and Methods: Seventy one 45- to 75-years-old male volunteers with coronary artery disease (32 diabetic & 39 non diabetic patients) participated in 6-8 weeks of moderate intensity aerobic exercise training consisting of 45 min sessions of  treadmill, stationary bicycle and arm bicycle. Anthropometric measurements of obesity (body mass index (BMI), waist circumference, hip circumference, waist the hip ratio and waist to height ratio) were measured at the beginning, in the middle and at the end of exercise sessions in both groups.

Results: Following the cardiac rehabilitation program, all of the anthropometric measurements except hip circumference in diabetic patients decreased significantly (P<0.05). BMI, waist circumference and waist to height ratio  increased in non diabetic patients (P<0.05).

Conclusion: Exercise training alone in cardiac rehabilitation program is not sufficient to reduce the anthropometric measurements of obesity in non-diabetic patients.

Background and Aim: Perceptual motor abilities are based on motor functions and conceptual growth. Therefore, regarding the weak perceptual motor abilities in mental retarded children, it will be an effective step in eliminating their learning problems and improving their functional activities at school, at home and in the society. The purpose of this study is to investigate the effect of instruction of balance exercises along with gross movement exercises on the balance function and gross movement in mental retarded children.

Materials and Methods: Using a simple non-probability sampling method, based on a pilot sample and the sample size formula were considered 10 children in the treatment group and 10 children in the control group. Inclusion criteria include educable children with mental retardation without significant skeletal, neurological and mental illness and the age group is between 4.5 to 14.5 years. Exclusion criteria include uncooperative child and absence of more than one session. Treatment group for 10 weeks, 3 sessions per week for 30-minute exercises; balance training and gross motor was taught. No intervention was done on control group. Then all subjects retested. The effectiveness of the treatment on balance and gross motor function were performed by statistical analysis.

Results: Before treatment, balance and gross motor scores were not significant (P&ge;0.05) between the intervention and control groups. In the interventional group, gross motor scores were significant (P&le;0.05) but balance scores were not significant (P&ge;0.05). Balance and gross motor scores between pre-and post-intervention in control group were not significant (P&ge; 0.05).

Conclusion: Lack of experience in the motor skills resulted poor motor skills in mental retarded children. Therefore, according to the findings of this study, we can provide requirements for gaining motor experiences with planning, targeted training and utilization of effective rehabilitation and occupational therapy.
