dc.description.abstractBackground: Cardiovascular disease (CVD) is now the leading cause of death in individuals with spinal cord injury (SCI). The SCI population is among the least physically active in society. Physical activity is known to reduce risk factors for CVD. The role of intensity of aerobic arm exercise in individuals with a chronic SCI is not fully investigated. Purpose: To compare the effects from aerobic high intensity interval training (HIT) (85% - 95% of peak heart rate (HR peak )) and isocaloric aerobic continuous moderate exercise (CME) (70% of HRpeak ) on peak oxygen uptake (VO2peak ), waist circumference (WC) and endothelial function measured as flow-mediated dilatation (FMD) in the brachial artery. Methods: 10 individuals with SCI paraplegia were randomized to HIT or CME arm crank exercise three times a week for eight weeks. Results: No significant differences in VO 2peak between the groups from baseline to post-test were found. However, there was a favorable trend towards a higher increase in VO 2peak in the HIT group compared to the CME group, 28.1±7.5 ml∙ kg -1 ∙min -1 -31.2±8.8 ml∙ kg -1 ∙min -1 versus 24.6±6.9 ml∙ kg -1 ∙min -1 - 23.8±5.4 ml∙ kg -1 ∙min -1 , respectively, (P= 0.051). No difference in FMD or WC within or between the groups from baseline to posttest was found. Conclusions: The findings from the present pilot study showed no significant difference between high- and moderate intensity arm crank exercise in terms of VO 2peak , waist circumference or flow-mediated dilatation. However, there was a favorable trend towards a higher increase in VO 2peak from arm crank exercise at aerobic high intensity compared to isocaloric exercise at moderate intensit y. Exercise at aerobic high intensity was feasible for the individuals with SCI paraplegia in this study. Future randomized studies with larger sample sizes to confirm our findings are needed. Relevance: Evidence based practice is essential to assure the best possible quality of rehabilitation medicine, and in this case, for the cardiovascular health of individuals with SCI paraplegia. The findings from the present study may be incorporated into daily treatment routines, and will contribute with new knowledge in the development of exercise guidelines for the SCI population.nb_NO
