EXERCISE TRAINING AND WEIGHT LOSS: AN OVERVIEW

APARNA RATHI

Abstract

Obesity is the result of excess energy intake compared to energy expenditure. In order to lose weight, a negative energy balance must be evoked and to maintain lost weight, energy balance must be maintained. Energy balance is the key concept for weight loss and maintenance. Exercise requires energy in the form of calories as a fuel, with the specific energy requirements dependent at least on weight and fitness level of the person, and the duration, intensity, and type of the exercise. There are various researches which show different modalities for weight loss i.e., Pedometer-based step goal, Aerobic exercise training only, Resistance training only, Aerobic and resistance training only and caloric restriction combined with aerobic exercise training. . Exercise of approximately 150–200 minutes per week with an energy equivalent of approximately 1000–2000 kcal/wk has been shown to be effective for weight maintenance and is superior to lesser amounts of exercise. Weight and resistance training may improve metabolism over time. Although, resistance ET alone contributes to the reduction of body fat, the effect on overall weight loss is minimal. Caloric restriction appears to have a more profound and consistent effect on weight loss compared to exercise training alone. Caloric restriction combined with aerobic exercise training achieves 9 kg-13 kg of weight loss. caloric restriction combined with moderate-to-vigorous aerobic exercise could attenuate the muscle loss which was consistent with the findings of previous studies that synergy of diet and exercise appeared more effective in improving muscle loss than dietary approaches in isolation.
