Two-handed isometric pulling strengths at different floor-slope angles.
This study recruited 10 Taiwanese men (M age=20.4 yr., SD=1.9) to examine the effects of exertion height (30%, 50%, 70%, and 90% stature) and ascending floor-slope angle (0 degrees, 5 degrees, 10 degrees, and 15 degrees) on maximum horizontal isometric pulling strengths. Analysis showed pulling strength decreased linearly with exertion height and increased linearly with floor-slope angle. The pulling strength at the exertion height of 90% stature was only 35% to 40% of that of 30% stature. The pulling strength of the 15 degrees floor-slope angle was approximately 127.6% to 150.9%, dependent on exertion height, of that of the 0 degrees floor-slope angle. The linear correlations between pulling strength and exertion height and between pulling strength and floor-slope angle were linear.
