Motl RW, Fernhall B. Accurate prediction of cardiorespiratory fitness using cycle ergometry in minimally disabled persons with relapsing-remitting multiple sclerosis. OBJECTIVE: To examine the accuracy of predicting peak oxygen consumption (Vo(2peak)) primarily from peak work rate (WR(peak)) recorded during a maximal, incremental exercise test on a cycle ergometer among persons with relapsing-remitting multiple sclerosis (RRMS) who had minimal disability. DESIGN: Cross-sectional study. SETTING: Clinical research laboratory. PARTICIPANTS: Women with RRMS (n=32) and sex-, age-, height-, and weight-matched healthy controls (n=16) completed an incremental exercise test on a cycle ergometer to volitional termination. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Measured and predicted Vo(2peak) and WR(peak). RESULTS: There were strong, statistically significant associations between measured and predicted Vo(2peak) in the overall sample (R(2)=.89, standard error of the estimate=127.4mL/min) and subsamples with (R(2)=.89, standard error of the estimate=131.3mL/min) and without (R(2)=.85, standard error of the estimate=126.8mL/min) multiple sclerosis (MS) based on the linear regression analyses. Based on the 95% confidence limits for worst-case errors, the equation predicted Vo(2peak) within 10% of its true value in 95 of every 100 subjects with MS. CONCLUSIONS: Peak Vo(2) can be accurately predicted in persons with RRMS who have minimal disability as it is in controls by using established equations and WR(peak) recorded from a maximal, incremental exercise test on a cycle ergometer.
