Effect of long-term ingestion of chicken extract on muscular power for middle and advanced age groups

Abstract

The effects of carnosine and anserine rich chicken extract on muscular power and fatigue sensation in middle and advanced age groups were investigated. Twenty middle and advanced aged healthy volunteers were divided into two groups and administered chicken extract at 1500 mg/day (225 mg/day as carnosine + anserine) or 0 mg/day for 4 weeks. Before and after the administration period, isokinetic knee extension power, flexion power, and one-leg standing time with eyes open were assessed. Chicken extract administration significantly increased knee extension power and one-leg standing time. These results suggest that carnosine- and anserine-rich chicken extract administration effectively improves muscular power in middle and advanced age.
