Relative changes in muscle oxygenation of the exercising upper arm and resting forearm. Relative changes in the oxyhemoglobin (Δoxy-Hb) and deoxyhemoglobin (Δdeoxy-Hb) concentrations of the (A, B) exercising upper arm and (C, D) resting forearm during static elbow flexion at 35% of maximal voluntary contraction with (EX + VIB) and without (EX) vibration of the biceps brachii tendon. Data expressed as mean ± standard error. *P <0.05, difference between EX and EX + VIB; †P <0.05, difference from baseline level during EX; ‡P <0.05, difference from baseline level during EX + VIB.
