Effect of Short-Term, High-Intensity Exercise on Anaerobic Threshold in Women.
Evans, Blanche W.
This study investigated the effects of a six-week, high-intensity cycling program on anaerobic threshold (AT) in ten women. Subjects trained four days a week using high-intensity interval-type cycle exercises. Workouts included six 4-minute intervals cycling at 85 percent maximal oxygen uptake (VO sub 2 max), separated by 3-minute intervals of lower intensity cycling at 25% VO sub 2 max. AT and VO sub 2 max were assessed prior to and immediately following the 6-week program, and VO sub 2 max was reassessed weekly in the exercise group. A significant interaction effect was found for cycle ride time and for AT expressed in liters, mililiters, work rate, and as a percentage of max. Further analysis of the significant interaction effects revealed no significant pretest to posttest differences in any variable in the control group, while the exercise group showed significant differences in these variables from pretest to posttest. Results suggest that, in women, high-intensity cycling exercise significantly increases physical work capacity (cycle ride time) and AT measures without substantial changes in VO sub 2 max parameters.
