Relationship between exercise time to exhaustion during treadmill exercise and total fat mass. Linear regression analyses identified strong negative correlations for the control clothing condition (R2 = −0.90, P < .001) and the partial uniform condition (R2 = −0.69, P = .003) but not the full uniform condition (R2 = −0.36, P = .07). C indicates control clothing condition; F, full uniform condition; P, partial uniform condition.
