    Group mean shoulder forces—(A) Fx, anterior and posterior force; (B) Fy, superior and inferior force; (C) Fz, medial and lateral force; and (D) resultant force—during 3 speeds of propulsion. The transition from push phase to recovery is shaded because it differs slightly between speed conditions.
