进行了一项实验室研究，以确定不对称举重对心理生理确定的最大可接受重量和最大自愿等长强度的影响。13名男大学生使用自由式举升技术，在矢状面上以三种不同的不对称角度(30、60和90°)将三个不同的箱子从地板上举起到81厘米高的桌子上。对于每个提举任务，在提举的起始处测量最大自愿等长强度。在3种盒子尺寸下，在矢状面上，不对称提举的最大可接受重量和静强度均显著低于对称提举(P<；0.01)。最大可接受重量和静态强度相对于矢状面的值随不对称角度的增加而增加(P<；0·01)。盒子大小对最大可接受重量或自愿等长强度相对于矢状面的下降百分比没有显著影响(P≥0·05)。改正面孔...
A laboratory study was conducted to determine the effects of asymmetric lifting on psychophysically determined maximum acceptable weights and maximum voluntary isometric strengths. Thirteen male college students lifted three different boxes in the sagittal plane and at three different angles of asymmetry (30,60 and 90°) from floor to an 81-cm high table using a free-style lifting technique. For each lifting task, the maximum voluntary isometric strength was measured at the origin of lift. The maximum acceptable weights and the static strengths for asymmetric lifting were significantly lower than those for symmetric lifting in the sagittal plane for three box sizes (P<0·01). The decrease in maximum acceptable weight and static strength from the sagittal plane values increased with an increase in the angle of asymmetry (P < 0·01). Box size had no significant effect (P≥ 0·05) on the percentage decrease in maximum acceptable weight or voluntary isometric strength from the sagittal plane values. Correction fac...
