Elastic energy storage at the shoulder also augments the generation of joint velocity and power at the elbow. During acceleration, the elbow extends at very high angular velocities (2,434±552°/sec) despite large amounts of negative power and work (−246±63J), indicating that the triceps alone are not powering this rapid extension ( Fig. 2 ).
