Effect of exercise on postoperative nitrogen balance.

H Freund, N Yoshimura, J E Fischer

    Journal of Applied Physiology: Respiratory, Environmental and Exercise Physiology
    |January 1, 1979
    PubMed
    Summary

    Postoperative exercise alongside parenteral nutrition boosts muscle amino acid turnover without affecting nitrogen balance. This suggests exercise aids muscle recovery by increasing amino acid utilization and synthesis.

    Area of Science:

    • Physiology
    • Metabolic Research
    • Exercise Science

    Background:

    • Postoperative recovery often involves muscle catabolism and altered amino acid metabolism.
    • Parenteral nutrition is a common support method, but its impact on muscle metabolism needs further investigation.
    • The role of exercise as an adjunct therapy in this context is not fully understood.

    Purpose of the Study:

    • To investigate the influence of exercise on postoperative muscle catabolism, amino acid metabolism, and nitrogen balance.
    • To determine if exercise impacts amino acid levels in plasma and muscle tissue.
    • To explore the mechanisms behind exercise's effect on skeletal muscle amino acid turnover.

    Main Methods:

    • Twenty male Sprague-Dawley rats were divided into exercised and nonexercised groups.
    • All rats received parenteral nutrition via jugular vein infusion for 96 hours.
    • Exercised rats underwent treadmill running for 15 minutes daily for 3 days.

    Main Results:

    • No significant differences were observed in nitrogen balance or body weight change between groups.
    • Plasma amino acid concentrations were 15% lower in the exercised group.
    • Skeletal muscle free amino acid concentrations were 66% higher in the exercised group.

    Conclusions:

    • Exercise, as an adjunct to parenteral nutrition, stimulates amino acid turnover in skeletal muscle postoperatively.
    • This increased turnover involves amino acid consumption for energy metabolism and gluconeogenesis, alongside protein synthesis.
    • The net effect results in nitrogen equilibrium comparable to nonexercised controls, indicating a beneficial role in muscle recovery.
