Development of a maximal testing protocol for the NordicTrack cross-country ski simulator.Med. Sci. Sports Exerc.,Vol. 31, No. 4, pp. 619-623, 1999.Purpose:The purpose of this study was to develop a valid &OV0312;O2maxtesting protocol for the NordicTrack (NT) cross-country ski simulator.Methods:To be considered a valid protocol, it was felt that the maximal values obtained from the cross-country skiing (XC) test should be similar to those obtained from a maximal graded treadmill (TM) test. During pilot testing, cadence (strides·min−1), arm resistance, leg resistance, and grade were individually manipulated to study the effect on measured &OV0312;O2. A protocol for the NT was developed from the findings of the pilot study, and the results were compared with a TM &OV0312;O2maxtest utilizing the Bruce protocol. Thirteen male and 15 female volunteers (aged 22-49 yr) served as subjects and completed both tests in random order. The maximal physiological responses from the XC and TM max tests were compared using pairedt-tests.Results:There were no significant (P> 0.05) differences in maximal &OV0312;O2(42.5 vs 42.6 mL·kg−1·min−1; 3.27 vs 3.31 L·min−1), heart rates (HR; 185 vs 185 bpm), or ratings of perceived exertion (RPE; 19.0 vs 19.1) for the XC and TM tests. There were significant (P< 0.05) differences for maximal &OV0312;E (124.5 vs 118.6 L·min−1) and respiratory exchange ratio (RER; 1.15 vs 1.21) between the XC and TM tests, respectively.Conclusions:It was concluded that the testing protocol developed for the NT XC simulator is valid and can be expected to elicit similar maximal values when compared with TM testing.
