Abstract
External load, N = 8), STAIR (no load, N = 9), and CONTROL (N = 7) were tested. By week 4, subjects warmed up 5 min on a cycle ergometer followed by 35 min on the stairclimber at 80–85% maximum heart rate (MHR) 4 d.wk−1. In week 6, the LOAD group carried an external load of 4% of body weight increasing to 8% for weeks 7–12. STAIR and LOAD group significantly increased (P < 0.01) VO2max by 11.1% and 9.6%, respectively. Isokinetic strength tests showed increased (P < 0.05) peak torque and total work for STAIR and LOAD at 120 and 180°.s−1. For total work, a significant increase (P < 0.05) of 10.5% was observed at 60°.s−1 for the LOAD group. The results indicate stairclimbing is an appropriate exercise for middle-aged females improving both aerobic capacity and strength following 12 wk of training. ©1994The American College of Sports Medicine...
