  Background: Sarcopenia, is a major concern for our aged society because sarcopenia is a fundamental cause of frailty and functional disability. Aim: The effects of catechin-ingestionp and/or heat treatment on the volume in quadriceps muscles, isometric force of knee extension, and serum thiobarbituric acid reactive substances (TBARS) were investigated in healthy elderly women. Methods: Subjects (71.0 ± 0.7 years old, n=27) were divided into 3 groups; 1) catechin-ingested, 2) heatstressed, and 3) catechin-ingestion with heat stressed (catechin+heat) groups. Subjects in both catechin-ingested and catechin+heat groups daily ingested 350 ml of green tea containing 540 mg of catechin in one hour for 10 weeks. Heat stress was applied on the quadriceps muscles for 8 hours a day and 4 days a week by using two heat- and steam generat.. View More»
