Abstract: | Kraemer, William J., Jeff S. Volek, Kristine L. Clark, ScottE. Gordon, Thomas Incledon, Susan M. Puhl, N. Travis Triplett-McBride, Jeffrey M. McBride, Margot Putukian, and Wayne J. Sebastianelli. Physiological adaptations to a weight-loss dietary regimen andexercise programs in women. J. Appl.Physiol. 83(1): 270-279, 1997.Thirty-one women(mean age 35.4 ± 8.5 yr) who were overweight were matched andrandomly placed into either a control group (Con; n = 6), a diet-only group (D;n = 8), a diet+aerobic endurance exercise training group (DE; n = 9),or a diet+aerobic endurance exercise training+strength training group(DES; n = 8). After 12 wk, the threedietary groups demonstrated a significant(P 0.05) reduction in body mass,%body fat, and fat mass. No differences were observed in the magnitudeof loss among groups, in fat-free mass, or in resting metabolic rate.The DE and DES groups increased maximal oxygen consumption, and the DESgroup demonstrated increases in maximal strength. Weight loss resultedin a similar reduction in total serum cholesterol, low-densitylipoprotein cholesterol, and high-density lipoprotein cholesterol amongdietary groups. These data indicate that weight loss during moderatecaloric restriction is not altered by inclusion of aerobic oraerobic+resistance exercise, but diet in conjunction with training caninduce remarkable adaptations in aerobic capacity and muscular strengthdespite significant reductions in body mass. |
