Abstract:

The aim of this study is to investigate the effects of regular exercise of walking on body  weight, body mass index (BMI), waist and hip circumference, waist - hip ratio and body fat percentage (BFP) in sedentary obese women. 30 obese sedentary women (age: 36.93 ± 11.10 years; height: 157.50 ± 4.73 cm, body weight: 77.89 ± 10.98 kg) participated in the study. Subjects participated in 8 weeks, 5 days per week, exercise intensity of 75% compared to the Karvonen formula, built in 75-minute walking of workout (total of 40 exercises). During the exercices heart rate of participants were followed by heart rate monitors. The first measurement was processed on the first day of exercise programme and the last measurement was done at the end of eigth weeks of exercise. Nutrient uptake was limited to with a diet program by an dietician, during eight weeks of the exercise session. As a result of the measurements were made for after exercise,  body weight, BMI, waist circumference and hip circumference values statistically significant differences were observed. (p <0.05). In addition to this, despite the reduction in fat percentage was not statistically significant, there was a change in fat percentage (pre-test: 37.3 ± 4.85% - post test: 36.92% ± 4.95)  (p> 0.05). On the other hand,  there was no statistically significant difference in waist - hip ratio values before and after 8 weeks of exercise (p> 0.05). Results of this study in obese sedentary women in 8 weeks, 5 days a week, based on Karvonen formula 75% intensity of exercise, the walking exercise for 75 minutes is thought to be effective on weight, BMI, waist and hip circumference, waist - hip ratio and BFP as well as some body parameters.
