Background. Determinant factors of aerobic fitness have not been clearly demonstrated in individuals with brain injury.
Aim. To investigate the relationship between aerobic fitness and gender, age, intensity and total duration of aerobic physical activity, and skewness of the frequency distribution of 6-h continuous heart rate values in a larger sample of adults with brain injury.
Design. Cross-sectional and correlative study.
Setting. Research laboratory setting.
Population. Thirteen adult women and 20 adult men with cerebral palsy or stroke participated in this study.
Method. VO2max was estimated using the multistage submaximal cycle ergometer test. Heart rate was recorded continuously for 6 h on a weekday. Relationships between predicted VO2max and gender, age, intensity and total duration of aerobic physical activity, skewness of frequency distribution, and average heart rate over 6 h were determined.
Results. Significant differences were seen in predicted VO2max between genders (P < 0.05). Predicted VO2max correlated significantly only with the skewness of the frequency distribution of values for continuous heart rate (r = -0.53, P < 0.01).
Conclusion and Clinical Rehabilitation Impact. The results suggest that brief and frequent physical activity may also improve aerobic fitness in adults with brain injury.
