APFT performance, injury incidence, and IL-6 response to ROTC-PT based on sleep duration. (A) Prospective injury incidence was not significantly different between groups based on average self-reported sleep duration. (B) Average sleep duration was not significantly different between injured and uninjured cadets. (C) APFT score was not different between cadets with different sleep durations. (D) Salivary IL-6 increased in response to exercise, but was not different between cadets with different sleep durations, or on different days. Data are presented as mean ± SEM. * different from ‘PRE’.
