Abstract
The aim of this study was to compare the maximum oxygen consumption (VO2max) between road cyclists with and without risk for eating disorders. he sample was composed of 43 cyclists aged 18-25 years, participants of the road cycling championship of the State of Pernambuco. VO2max was measured by a computerized metabolic analyzer during an incremental test in cycleergometer. he initial test load was 50 W, with increments of 25 W every minute until volitional exhaustion or inability to maintain the current load. To evaluate disordered eating behaviors (DEB), the Eating Attitudes Test was used (EAT-26). Univariate analysis of covariance (ANCOVA) was used to compare the VO2max between cyclists with (EAT-26 ≥ 21) and without (EAT-26 < 21) risk for eating disorders. he indings showed statistically signiicant VO2max diference between cyclists with and without risk to eating disorders (F(2, 41)=28.44; p=0.01), indicating moderate effect size (d = 0.6). It was concluded that DEB was related to cyclists with lower VO2max.
Highlights
Road cycling is a cycling sport modality with endurance characteristics, usually performed outdoors, in which long distances are traveled on a bicycle (~ 250km)
VO2max is considered of extreme importance for athletes of cyclic endurance sports, such as road cycling, to support long competitive distances, as it ensures high energy performance throughout the cycling stage and favors rapid removal of metabolic acidosis accumulated among high-intensity muscular actions[5]
Longterm continuous exercises and/or moderate intensity interval exercises are used in training to improve VO2max[2], while, on the other hand, disordered eating behaviors (DEB) may attenuate it in athletes[6,7]
Summary
Road cycling is a cycling sport modality with endurance characteristics, usually performed outdoors, in which long distances are traveled on a bicycle (~ 250km). Studies have indicated that VO2max is closely related to aerobic and anaerobic capacity[3,4]. In this sense, VO2max is considered of extreme importance for athletes of cyclic endurance sports, such as road cycling, to support long competitive distances, as it ensures high energy performance throughout the cycling stage and favors rapid removal of metabolic acidosis accumulated among high-intensity muscular actions[5]. Hus, considering that cardiovascular overload is closely related to the decrease in aerobic performance[14,15], it could be concluded that DEB can generate VO2max attenuation. In view of the above, the aim of the present study was to compare VO2max values between road cyclists with and without risk for the onset of eating disorders. hen, based on the assertions of some researchers[6,7,8], a hypothesis was formulated for the present investigation: 1) road cyclists with higher DEB frequency present lower VO2max compared to cyclists with lower DEB frequency
