摘要	The maximum oxygen uptake ((V) over dot(2) max), determined from graded maximal or submaximal exercise tests, is used to classify the cardiorespiratory fitness level of individuals. The purpose of this study was to examine the validity and reliability of the YMCA submaximal exercise test protocol performed on a newly- designed rectilinear stepping ergometer (RSE) that used up and down reciprocating vertical motion in place of conventional circular motion and giving precise measurement of workload, to determine (V) over dot(2) max in young healthy male adults. Thirty-two young healthy male adults (32 males; age range: 20 - 35 years; height: 1.75 +/- 0.05 m; weight: 67.5 +/- 8.6 kg) firstly participated in a maximal-effort graded exercise test using a cycle ergometer (CE) to directly obtain measured (V) over dot(2) max. Subjects then completed the progressive multistage test on the RSE beginning at 50W and including additional stages of 70, 90, 110, 130, and 150W, and the RSE YMCA submaximal test consisting of a workload increase every 3 minutes until the termination criterion was reached. A metabolic equation was derived from the RSE multistage exercise test to predict oxygen consumption ((V) over dot(2)) from power output (W) during the submaximal exercise test ((V) over dot(2)(mL . min(-1)) = 12.4 x W(watts) + 3.5 mL . kg(-1) min(-1) x M + 160mL . min(-1), R-2 = 0.91, standard error of the estimate (SEE) = 134.8mL . min(-1)). A high correlation was observed between the RSE YMCA estimated (V) over dot(2) max and the CE measured (V) over dot(2) max (r=0.87). The mean difference between estimated and measured (V) over dot(2) max was 2.5 mL . kg(-1) . min(-1), with an SEE of 3.55 mL . kg(-1) . min(-1). The data suggest that the RSE YMCA submaximal exercise test is valid for predicting (V) over dot(2) max in young healthy male adults. The findings show that the rectilinear stepping exercise is an effective submaximal exercise for predicting (V) over dot(2) max. The newly-designed RSE may be potentially further developed as an alternative ergometer for assessing cardiorespiratory fitness and the promotion of personalized health interventions for health care professionals.
