Physical training in insulin-resistant states.

M Berger, K Becker-Zimmermann, L Herberg

    International Journal of Obesity
    |January 1, 1982
    PubMed
    Summary

    Physical exercise can improve glucose tolerance and prevent insulin resistance, particularly in obese individuals. Further research is needed to understand the molecular mechanisms behind these beneficial effects.

    Area of Science:

    • Physiology
    • Endocrinology
    • Exercise Science

    Background:

    • Insulin resistance and glucose intolerance are significant health concerns, often linked to obesity.
    • Physical activity plays a crucial role in metabolic health.
    • Understanding the impact of exercise on glucose metabolism is vital for disease prevention and management.

    Purpose of the Study:

    • To review animal studies examining the effects of physical activity on glucose tolerance.
    • To explore the potential of exercise interventions for improving metabolic health.

    Main Methods:

    • Review of animal experimentation, focusing on studies involving normal and obese Zucker rats.
    • Analysis of research investigating the impact of varying physical activity levels on glucose metabolism.

    Main Results:

    • Mild-intensity physical training demonstrated the ability to partially reverse or prevent insulin resistance, glucose intolerance, and skeletal muscle insulin insensitivity in rats.
    • These effects were observed in both normal and obese rat models.

    Conclusions:

    • Physical exercise programs show promise for improving glucose tolerance in patients with type 2 diabetes mellitus, especially when obesity is a contributing factor.
    • The precise molecular mechanisms underlying exercise-induced improvements in glucose tolerance require further investigation.
