Insulin-responsive glucose transporter (GLUT-4) content increases by 1.8-fold in skeletal muscle with 14 wk of exercise training [Houmard et al. Am. J. Physiol. 264 (Endocrinol. Metab. 27): E896-E901, 1993]. The purpose this study was to determine whether more short-term (7 days) GLUT-4 protein human muscle. Seven sedentary men [25.0 +/- 1.1 (SE) yr, 44.1 2.2 ml.kg-1.min-1 maximal O2 uptake, 14.9 2.1% body fat] were examined before and after 7 days cycle ergometer (1 h/day, 76 2% heart rate). Needle biopsy samples from the vastus lateralis used content. Muscle increased (P < 0.05) an average 2.8 0.5-fold training. thus substantially
