Purpose

The purpose of the present study was to determine the reliability of the exercise response predicted peak VO2 using the total body recumbent stepper TBRS submaximal exercise test in: 1 healthy adults 20–70 years of age and 2 adults participating in inpatient stroke rehabilitation. We hypothesized that the predicted peak VO2 Visit 1 would have an excellent relationship r > 0.80 to predicted peak VO2 Visit 2. We also wanted to test whether the exercise response at Visit 1 and Visit 2 would be significantly different.

Methods

Healthy adults were recruited from the Kansas City metro area. Stroke participants were recruited during their inpatient rehabilitation stay. Eligible participants completed 2 TBRS submaximal exercise tests between 24 hours and 5 days at similar times of day.

Results

A total of 70 participants completed the study. Healthy adults n = 50 were 36 M, 38.1 ± 10.1 years and stroke participants n = 20 were 15 M, 62.5 ± 11.8 years of age. The exercise response was reliable for healthy adults r = 0.980, p<0.01 and stroke participants r = 0.987, p<0.01 between Visit 1 and Visit 2. Repeated Measures ANOVA showed a significant difference in predicted values between the two visits for healthy adults 47.2 ± 8.4 vs 47.7 ± 8.5 mL∙kg-1∙min-1; p = 0.04 but not for stroke participants 25.0 ± 9.9 vs 25.3 ± 11.4 mL∙kg-1∙min-1; p = 0.65.

Conclusion

These results suggest that the exercise response is reliable using the TBRS submaximal exercise test in this cohort of healthy adults and stroke participants.
