Abstract

Purpose: The aim of this investigation was to compare gender differences in physiologic and perceptual responses during a 1-h run at recent marathon pace and running economy at three speeds in recreational marathon runners. Methods: In a counterbalanced design, 10 men and 10 women completed a 1-h treadmill run and a running economy test. Treadmill, speed for the 1-h run ranged, from 141 to 241 m·min-1 and 134, 168, and 188 m·min-1 for running economy. Physiologic parameters (oxygen uptake, carbon dioxide production, pulmonary ventilation, and heart rate) and perceived exertion were measured. Repeated-measures ANOVA was used to compare any gender differences (P < .05) during the 1-h run and a two-way ANOVA was used to compare running economy. With this sample, estimated marathon energy expenditure, body composition, and maximal physiologic function was reported.1 Results: With the exception of an allometric expression of VO2 (mL·min-1-kg BW-0.75), similar gender physiologic and perceptual responses were found during the 1-h run. Although not significant, the females exercised at a higher percent VO2max (8% to 9%) during the run. Similar gender differences were also noted during the running economy tests. Conclusions: Although the male runners completed a recent marathon significantly faster than the females, similar gender physiologic and perceptual responses were generally found during the 1-h treadmill run and the running economy tests. © 2009 Human Kinetics, Inc.
