Protein supplementation increases both strength and muscle mass

 PubMed

BACKGROUND:

Protein ingestion after a single bout of resistance-type exercise stimulates net muscle protein accretion during acute postexercise recovery. Consequently, it is generally accepted that protein supplementation is required to maximize the adaptive response of the skeletal muscle to prolonged resistance-type exercise training. However, there is much discrepancy in the literature regarding the proposed benefits of protein supplementation during prolonged resistance-type exercise training in younger and older populations.

OBJECTIVE:

The objective of the study was to define the efficacy of protein supplementation to augment the adaptive response of the skeletal muscle to prolonged resistance-type exercise training in younger and older populations.

RESULTS:

Data were included from 680 subjects. Protein supplementation showed a positive effect for FFM  and 1-RM leg press strength compared with a placebo after prolonged resistance-type exercise training in younger and older subjects.

CONCLUSION:

Protein supplementation increases muscle mass and strength gains during prolonged resistance-type exercise training in both younger and older subjects.
A new meta-analysis concludes that protein supplementation increases both strength and muscle mass in younger and older trainees engaged in prolonged resistance exercise.
