Preventing disordered eating in athletes
Purpose
Athletes - especially endurance athletes like distance runners and aesthetic athletes like gymnasts - are much more likely than the general public to develop unhealthy eating habits and even eating disorders.
This research will examine specific psychological traits - impulsiveness, the ability to delay reward, and cognitive flexibility - to see if these traits predict which athletes develop disordered eating during their competition seasons.
Impact
Eating disorders can lead to increased risk of injury, poorer reproductive health, dangerously low bone density later in life, poorer physical performance, and other ongoing physical and mental health problems.
The ways people develop eating disorders are not well understood. This research could help identify who is at risk for disordered eating so that we can prevent problems before they occur.
We believe that the stress of a competitive sports season will prompt eating behaviors in some athletes to worsen, possibly to the development of clinical eating disorders, and we want to understand whether basic psychological functions tell us anything about who is susceptible.
Study Methods
Researchers will follow 40 male and 40 female athletes over the course of their sports seasons. Psychological, physiological, metabolic, and hormonal data will all be collected and evaluated.
Previous Contributions
The Women's Health and Exercise Lab has contributed over two decades of leading research on inter-related health outcomes of metabolism, reproductive function, and bone health.
