The effect of load intensity on back muscle oxygenation in static muscle work

Localized muscle fatigue can be a limiting factor for prolonged static work at the workplace. It is important to study the etiology of fatigue; previous literatures suggest that fatigue is associated with musculoskeletal injury and low back pain (Gorelick et al., 2003; Kankaanpää et al., 1998; Kumar et al., 2001; Kumar & Narayan 1998; Payne et al., 2000; Tsuboi et al., 1994).
