Benefits of Aerobic Conditioning and Diet for Overweight Adults

Abstract

Excess bodyweight and obesity are one of the most common problems facing adult men and women of modern industrialised societies. Obesity is associated with alternations in glucose tolerance and lipoprotein profiles, which produces an increased risk for coronary heart disease. Starvation and low-calorie diets under 500 kcal/day reduce bodyweight and fat, but serious life-threatening problems can develop. For these reasons, moderate caloric restrictions between 1000 and 1500 kcal/day have been shown to produce the most successful long term weight loss. Exercise conditioning without caloric restrictions has been shown to reduce bodyweight, primarily fat weight, and increase lean bodyweight. However, this occurs only when the energy expenditure is greatly elevated and the exercise sessions are long in duration. Well controlled multiple-group studies indicate that exercise combined with caloric restriction is the best method for bodyweight and fat reduction. Including exercise in the diet regimen increases cardiorespiratory functional capacity, decreases cholesterol and triglyceride levels, and helps to retard the loss of lean muscle mass. The diet and exercise prescription which produces the best and safest results includes a diet of approximately 1200 kcal/day and a physical activity programme of at least 3 days/week, 20 to 30 minutes in duration, and at a minimum intensity of 60% of maximum heart rate.

Activity level and risk of overweight in male health professionals.

“…Physical conditioning reduces fat mass and total body weight, increases lean body weight, and is associated with weight control independent of dietary factors.3-9 Exercise improves cardiorespiratory functional capacity and decreases serum lipid, glucose, and insulin levels. 9 year in which information concerning sedentary activity level was collected. Because our interest was in the activity-overweight relationship in healthy men, approximately 19% of the cohort with diseases that could alter activity level and/or weight were excluded from the analyses.…”

Influence of body weight reduction on maximal oxygen uptake in female elite athletes

“…min-'). The decrease in Ooz max may be caused by loss of muscle tissue, as suggested by Walberg (6) and Hagan (21). Furthermore, the BW in itself is an important part of the training load for elite endurance athletes.…”

The Effect of Combination between Cryolipolysis and Aerobic Exercise in Reducing Abdominal Adiposity Inobese Subject

“…Due to its acutely high energy cost and capacity to increase fat utilization, aerobic exercise is frequently recommended in conjunction with energy restriction. There are many different kinds of aerobic exercise that we can engage in, or we can combine two types, like walking and jogging (18) .…”

“…Due to the acutely high energy cost and ability to increase fat utilization, aerobic exercise is frequently recommended in conjunction with calorie restriction (7) . Numerous studies studied the impact of modest caloric restriction either separately or in addition to aerobic activity.…”
