We hypothesize that protein hydrolysate supplementation will attenuate the loss in muscle mass during 7 days of immobilisation and will augment the rate of muscle mass re-gain during recovery.

skeletal muscle mass (quadriceps muscle cross sectional area (CSA))
Achtergrond van het onderzoek
Recovery from illness and/or injury often requires a period of physical inactivity. Short periods of inactivity disrupt muscle protein synthesis and breakdown rates, which lead to a loss of skeletal muscle mass. A loss of skeletal muscle mass has been shown to slow recovery and impact quality of life. It is therefore important to develop strategies that can prevent the loss of skeletal muscle mass during periods of inactivity.With the present study, we will investigate whether dietary supplementation with a protein hydrolysate can attenuate skeletal muscle loss following 7 days of one-legged knee immobilisation and augment the rate of muscle mass re-gain during recovery in young men.
Doel van het onderzoek
We hypothesize that protein hydrolysate supplementation will attenuate the loss in muscle mass during 7 days of immobilisation and will augment the rate of muscle mass re-gain during recovery.
Onderzoeksopzet
1 week immobilisation, 2 weeks recovery
Onderzoeksproduct en/of interventie
Subjects will receive a nutritional supplement during immobilisation and recovery. This will be either a protein hydrolysate or a placebo
