About

The purpose of the study is to compare the effect of high-intensity interval training and intermittent fasting on improving body weight and functional capacity among overweight subjects.

Full description

Exercise improves cardiorespiratory fitness, muscle strength, endurance, body composition, and decreases visceral fat. The, increase in physical activity and modification of eating behaviors are the first line of interventions given because of their low costs and low risks of complications.

Most commonly, the continuous exercise of moderate intensity, that has to be performed several days of the week to get target benefits have been used, on the other hand, different forms of training which aim to reduce time spent exercising by increasing exercise intensity have been considered as an alternative to increasing adherence to the training program which is supported by some researches that may have greater benefits as high intensity interval training improves the vascular function of the muscle capillary density and endothelial nitric oxide synthase(eNOS) levels. But there are some overweight people even some of the young people have restriction to perform exercise programs due to any medical problem that could interfere with exercise.

So, searching for optimal dietary interventions for obesity is still ongoing, but the modification in eating behaviors are hampered by difficulties in coping with a different diet. So, the diet with a fasting component that will be used in this study may be more effective than other complex and restrictive diets as it essentially limits the caloric intake to a specified period without major diet composition changes.

So, the aim of this study is to compare the effect of high-intensity interval training and intermittent fasting on improving body weight and functional capacity among overweight subjects.
