STUDY DESIGN: Non-randomized study.
OBJECTIVES: Previous studies indicated that at least 2-h leg exercise at more than 60% maximum oxygen consumption (VO(2)max) increased plasma interleukin (IL)-6 in able-bodied (AB) subjects. The purpose of the present study was to compare IL-6 response to arm exercise in AB subjects and persons with spinal cord injury (SCI).
SETTING: Wakayama Medical University in Japan.
METHODS: Six subjects with SCI between T6 and T10 and seven AB subjects performed 2-h arm crank ergometer exercise at 60%VO(2)max. Plasma catecholamines, IL-6, tumor necrosis factor (TNF)-α and high-sensitivity C-reactive protein (hsCRP) were measured before exercise, 60-min exercise, immediately and 2 h after the completion of exercise.
RESULTS: Arm exercise increased myoglobin and plasma IL-6 levels in SCI and AB (P<0.01), but there were no differences in them between the two groups throughout the study. Plasma levels creatine kinase, lactate dehydrogenase, TNF-α and hsCRP did not change throughout the study in both groups.
CONCLUSION: These findings suggest neither significant muscle damage nor inflammatory response during exercise. The increase in plasma IL-6 in SCI was not unexpected, confirming that moderate intensity and relatively long-arm exercise is safe and beneficial for SCI subjects with regard to IL-6 excretion, as in AB subjects.
