| The effect on aerobic and anaerobic power of adding strength training to the aerobic program of fit women was investigated. Subjects were randomly assigned to endurance (E, n = 7) or endurance + strength (ES, n = 14). E and ES maintained endurance training (3.6 hrs/wk) while ES added high intensity strength training to their regimen (2d/wk for 6 wks >85% 1RM). VO2max, time to exhaustion (TE), and blood lactate response were determined on a bicycle. A Wingate test determined peak watts (w), w/kgLBM, and mean watts over 30 seconds (w/30). Vertical jump (VJ), and body composition were measured. E had no significant change (p < 0.05) in any variable. ES had no change in VO2max or blood lactate. However, ES significantly increased TE by 24 seconds (p = 0.003). Also, ES significantly improved the following: VJ = 22.3 +/- 11.5%, p = 0.000; w = 14.6 +/- 17.9%, p = 0.001; w/kg = 13.2 +/- 18.0%, p = 0.004; w/kgLBM = 12.1 +/- 18.3%, p = 0.10; w/30 = 14.7 +/- 23.1, p = 0.021; lean body mass = 1.1kg, p = 0.007; and significantly reduced bodyfat by 1.5% (p = 0.027). |
