Fig. 2From: The effects of hypoxia on muscle deoxygenation and recruitment in the flexor digitorum superficialis during submaximal intermittent handgrip exerciseMuscle saturation of oxygen (SmO2) and changes in oxy- (ΔO2Hb), deoxy- (ΔHHb) and total hemoglobin (ΔtHb) during each quintile of hand grip exercise (HGE) from baseline until task failure (100%) in the flexor digitorum superficialis under hypoxic and normoxic conditions. Values are presented as mean ± SEM. Open markers indicate significant differences from baseline, asterisks denote significant differences from task failure, †indicates significant difference between hypoxic and normoxic conditions (p < 0.05)Back to article page
