Young Athlete

Determinants of Skeletal Health in Male Athletes


A study for 16-30 year-old male athletes who are running at least 30 miles/week

Also seeking 16-30 year-old males who exercise for < 2 hours/week

Study Aim

Research in female athletes has shown that high levels of exercise can cause low energy availability, hormonal irregularities, and impaired bone density. However, similar studies in males have not yet been conducted. In this study, we aim to investigate whether male athletes are also at risk for compromised bone strength due to low energy availability and resultant hormonal irregularities.

This study is 18 months long including a screening visit to assess eligibility, main visits at baseline and 12 months, and check-ins at 4, 8, and 18 months. 


We are currently recruiting participants for a baseline-only visit, as outlined below.
