Figure 1.
Graphic schema of the events during a longswing. On the left side, Middle grasping hand marker (1) and the center of mass (2) defined the body position angle (θΒΈ) in relation to the z axis. The illustrations shows the initial position (Pi), final position (Pf) and longswing events (P1, P2, and P3) from the hip (H) and shoulder (S) joints. Hip and shoulder events have been represented at the same instant of time for P1-P3 for simplicity. On the right side, definitions of the markers (elbow, shoulder, great trochanter and femoral condyle), joint angles (hip and shoulder), and segmental angles (arm, trunk, and thigh) are depicted.
