Details and patient eligibility


The purpose of the study is to compare the effect of high intensity interval training and low intensity training on physical fitness among adult overweight.

Full description

Excess body weight has been shown to negatively influence musculoskeletal health and may limit physical function. Thus, there is a need for effective interventions to reduce body weight in those individuals who may already be overweight or obese. Physical activity can be an important component of lifestyle interventions for weight loss. Thus, it is important for clinicians, health care providers, and health-fitness professionals to recognize the influence of physical activity on body weight and to understand recommendations that can affect physical activity behavior. Several studies reported that HIIT can improve cardiorespiratory fitness (increase vo2 max) in adults with varied body weight and health status. High intensity interval training induced improvements in insulin sensitivity, blood pressure, and body composition more consistently occur in adults with overweight, with or without high risk of cardiovascular disease and diabetes especially if these participate in prolonged exercise program up to 12 or more weeks. Low intensity exercise has been shown to have a range of physiological and biochemical effects during a subsequent bout of exercise Low intensity exercise would result in muscle acetyl group accumulation and thereby would accelerate mitochondrial ATP production (and reduce ATP production from nonoxidative routes) during a subsequent bout of moderate intensity exercise. In accordance with these changes, we also hypothesized that the vo2 on-kinetics during moderate intensity exercise would be accelerated when preceded by low intensity exercise . The significant behind this study came up with the importance to declare the effect of high intensity interval training on improving physical fitness and body composition which be more suitable for overweight active people that don't have time to practice prolonged exercise during the week and this study also will investigates the effect of low intensity exercise on physical fitness and body composition to declare where is going to be beneficial for overweight sedentary subjects and compare it is effect with pervious. This study will be designed to provide a guideline about the effect of high intensity interval training& low intensity training exercise on physical fitness in the overweight adult patient.
