Effect of exercise on obesity.

J S Garrow

    Acta Medica Scandinavica. Supplementum
    |January 1, 1986
    PubMed
    Summary

    Physical training offers fitness and body composition benefits valuable for obesity treatment. However, severe obesity limits exercise capacity, making diet crucial for managing severe cases and exercise for mild obesity or prevention.

    Area of Science:

    • Obesity Research
    • Exercise Physiology
    • Nutritional Science

    Background:

    • Physical training improves fitness and body composition in normal-weight individuals.
    • Obesity often leads to reduced exercise tolerance, hindering participation in beneficial physical activity.
    • Potential benefits of exercise for obese individuals, such as reduced food intake or elevated metabolic rate, lack strong evidence.

    Purpose of the Study:

    • To evaluate the potential benefits of physical training for obesity treatment.
    • To address the limitations imposed by reduced exercise tolerance in severely obese individuals.
    • To examine the evidence supporting exercise's role in reducing food intake or increasing metabolic rate in obesity.

    Main Methods:

    • The study reviews existing literature on the effects of physical training on fitness and body composition.
    • It assesses the impact of obesity on exercise tolerance and the feasibility of exercise interventions.
    • The research analyzes the evidence for indirect benefits of exercise, including effects on appetite and metabolism.

    Main Results:

    • While physical training offers benefits, severely obese individuals may not tolerate sufficient exercise to achieve them.
    • There is insufficient evidence to support claims that exercise reduces voluntary food intake or significantly elevates metabolic rate in obesity.
    • The effectiveness of treatment strategies varies with obesity severity.

    Conclusions:

    • Obesity management is best achieved through a combination of dietary restriction and exercise.
    • Dietary restriction is paramount for severe obesity, while exercise plays a more significant role in managing mild obesity and prevention.
    • Further research may be needed to optimize exercise interventions for individuals with varying degrees of obesity.
