The purposes of this study were to compare the anaerobic performance of 19 active and 12 sedentary individuals with quadriplegia on the Wingate arm ergometric test and to investigate the relationship between participants’ demographic information (lesion level, time since injury, age, body mass) and their anaerobic performance variables. The following parameters were measured: peak power (PP), mean power (MP), lowest power (LP), time to achieve PP (t), fatigue index (FI), relative values of PP and MP with respect to body mass, and postexercise blood lactate accumulation (LA). Lowest power, MP, relative values of MP (rMP), FI and LApeak in the active group were significantly higher than in the sedentary group. There was a significant correlation between rMP and injury lesion level (p = .016). It was concluded that for active individuals with quadriplegia, muscle endurance (MP) and fatigability (FI) are higher than for sedentary individuals with quadriplegia.
