Mean ± standard error (SE) for each exercise performance estimated using analysis of covariance with adjustments for Model 1: age and service specialty adjustments; Model 2: the covariates in Model 1, body mass index, BUN and serum creatinine adjustments; Model 3: the covariates in Model 2, systolic blood pressure, fasting plasma glucose, alcohol intake status, cigarette smoking status, and weekly physical activity adjustments
