OBJECTIVES: To assess the feasibility of measuring @entity1576 ( @entity1576 ) in adults with @entity73 due to @entity64 . Secondary objectives are to assess reliability of @entity1576 over trials; assess whether @entity1 could sustain treadmill walking at @entity1576 ; and compare mean heart rate during sustained treadmill walking to estimated heart rate reserve (HRR). DESIGN: Cross-sectional, single-group design. SETTING: University research laboratory. @entity1 : Volunteer sample of adults (N=8) with impaired walking resulting from @entity64 . INTERVENTIONS: Three submaximal treadmill walking tests on 3 separate days; a 30-minute treadmill walking session on a fourth day. MAIN OUTCOME MEASURES: Gas exchange variables were measured, and 2 independent observers identified @entity1576 . Mean heart rate response to treadmill walking at @entity1576 was measured and compared with estimated 40% of HRR. RESULTS: @entity1576 was measured successfully in 88% of all trials. There was no difference in @entity1576 among trials (P=.17). After multiple imputations to account for 3 missing data points, the intraclass correlation coefficient was .87 (95% confidence interval, .80-.95). All @entity1 were able to walk for 20 minutes at @entity1576 . Mean    SD heart rate during the session was 66.0%  8.0% of estimated maximal heart rate. There was no significant difference between mean heart rate and estimated HRR values (P=.70). CONCLUSIONS: In adults with impaired walking resulting from @entity64 , @entity1576 can be safely measured during submaximal treadmill walking. @entity1 were able to sustain walking at @entity1576 , and this value may provide an appropriate stimulus for aerobic exercise prescription in this population.
