Why the study?
Does low energy availability (indicated by amenorrhea or low testosterone) impact bone injury rates and hormone levels in elite distance athletes?
Does low energy availability (indicated by amenorrhea or low testosterone) impact bone injury rates and hormone levels in elite distance athletes?
Current reproductive function provides a more objective and accurate marker of optimal energy for health than dietary and training estimation of energy availability, and is strongly associated with bone injury rates.

May warrant monitoring reproductive markers in elite runners; hypothesis-generating for energy-availability interventions.
