STUDY LIMITATIONS
During a sports championship, many hormonal factors can affect the
performance of athletes. Measuring salivary cortisol levels during a
long CrossFit® competition was important to understand the impact of
this sport on the body of athletes and to discover whether their
performance can be improved.
With increasing numbers of CrossFit® practitioners and more competitions
throughout the year, understanding the action of cortisol is critical,
either to identify overtraining or a differential diagnosis of
post-competition burnout syndrome.
The main limitation of this study was the impossibility to control the
rest time of athletes and to confirm if athletes did not use any
stimulant substance.
