PPF, peak pole force; MPF, mean pole force; M
max, ISO, maximum isometric torque; M
max, CON, concentric torque at 0° (trunk), 45° (shoulder) and 90° (elbow) joint flexion; M
RMS, mean concentric torque.***p < .001.**p < .010;*p < .050;Left pole forces were correlated to left shoulder/elbow strength and right pole forces were correlated to right shoulder/elbow strength.
