J Rehabil Res Dev. 2014;51(4):645–54. http://dx.doi.org/10.1682/JRRD.2013.08.0184 Slideshow Project DOI:10.1682/JRRD.2013.08.0184JSP Aim – Compare plasma inflammation-mediating cytokine response to handcycling (HC) with and without functional electrical stimulation (FES)-evoked lower-limb cycling. Relevance – Lower-limb paralysis and immobilization after spinal cord injury (SCI) result in increased relative adiposity and skeletal muscle atrophy. – Regular exercise may be therapeutic countermeasure to chronic inflammation and reduce chronic disease risk.

J Rehabil Res Dev. 2014;51(4):645–54. http://dx.doi.org/10.1682/JRRD.2013.08.0184 Slideshow Project DOI:10.1682/JRRD.2013.08.0184JSP Method On two separate occasions, 5 recreationally active, community-based participants with motor complete paraplegia performed 30 min HC and hybrid exercise (HYB) at fixed power output. Venous blood samples were collected at rest, immediately postexercise, 1 h postexercise (post+1), and 2 h postexercise (post+2). Plasma interleukin (IL-6, IL-10, IL-1 receptor antagonist (IL-1ra) adrenalin, and cortisol concentrations were determined via enzyme-linked immunoassay.

IL-1ra: – Unaffected. IL-10: – Nonsignificant 1-fold increase in HYB at post+2. Adrenaline and cortisol: – Increases immediately postexercise in HC and HYB.

HYB (vs HC alone) may provide greater anti- inflammatory potential in individuals with thoracic SCI.
