Abstract

Purpose: The aim of this study Aas to investigate the effect of 8 wk of exercise training on functional capacity. muscular strength, body composition, and vascular function in sedentary but healthy subjects by using a randomized. crossover protocol, Methods: After familiarization sessions. 19 subjects aged 47 +/- 2 yr (mean : SE) undertook a randomized. crossover design study of the effect of 8 wk of supervised circuit training consisting of combined aerobic and resistance exercise. Peak oxygen uptake ((V) over dot O-2peak). sum of 7 maximal voluntary contractions and the sum of 8 skinfolds and 5 segment girths vv ere determined at entry, crossover. and 16 Ak. Endothelium-dependent and -independent vascular function were determined by forearm strain-gauge plethysmography and intrabrachial infusions of acetylcholine (ACh) and sodium nitroprusside (SNP) in 16 subjects. Results: Training did not alter ACh or SNP responses.
