Methodological considerations
Despite the low number of participants, this study was robustly designed and the study subjects were carefully monitored under standardized conditions. By performing a maximal arm crank pre-test, participants exercised at the intended intensity, being a strength in this study. Astorino et al. showed that able-bodied participants needed a verification test to validate appearance of a ‘true’ peak VOAnother weakness in the study is that dietary intake of antioxidants were not examined. A difference in dietery intake could have explained some of the differences in exogenous antioxidant biomarkers between the SCI and the control group.
