Data presented as means ± SD. BM = body mass; EEE = exercise energy expenditure; FFM = fat-free mass; EA = energy availability. ^ p = 0.079, trend toward significance based on student’s t-test. * p < 0.05, ** p = 0.019, *** p < 0.008, statistically significant from low EA based on student’s t-test.
