The definition of the dominant leg (lateral dominance) is not clear, and there has been little reporting related to lateral dominance in the legs. To uncover the practical factors influencing which leg to use as the takeoff leg in 1-legged jumping movements, this study aimed to investigate the subjective dominance side of fundamental movements and to examine the lateral dominance of motor functions between the takeoff leg and non-takeoff leg. The subjects consisted of 27 young men who exercised regularly. They had not trained particularly on unilateral jumping. Fifteen men are the athlete group (left-legged jumpers group [LG]) using a left leg and 12 men are the athlete group (right-legged jumpers group [RG]) using a right leg as determined by a preliminary survey related to takeoff leg during high jump. The fundamental motions of the subjective dominant leg were investigated and the differences between the motor functions of takeoff and lead legs, such as sole shapes, single-leg vertical jump, 20-m hopping, ladder hopping, single-leg balance, and isokinetic strength were examined. It was found that many RG subjects (83%) tended to select the right leg for hopping, and many LG subjects (87%) tended to select the left leg for 1-legged balance. It was suggested that skilled movements show right-leg dominance in both takeoff leg groups. In the LG subjects, the left leg showed a higher value than the right leg in sole shape. The RG subjects showed a higher value in the right leg than in the left leg in a single-leg vertical jump. However, marked dominance was not found in the takeoff leg. The lower limbs may not show marked lateral dominance such as in the upper limbs.
优势腿（侧优势）的定义并不明确，关于腿部的侧优势，相关报道较少。为了揭示影响单腿跳跃运动中使用哪条腿作为起跳腿的实际因素，本研究旨在调查基本运动的主观优势侧，并检查起跳腿和非起跳腿之间的运动功能的侧优势。研究对象包括 27 名经常锻炼的年轻男性。他们没有特别训练单侧跳跃。15 名男性是运动员组（左腿起跳者组 [LG]），使用左腿，12 名男性是运动员组（右腿起跳者组 [RG]），根据与跳高起跳腿相关的初步调查确定使用右腿。研究了主观优势腿的基本运动，并检查了起跳腿和主导腿的运动功能差异，如脚底形状、单腿垂直跳跃、20 米跳跃、梯级跳跃、单腿平衡和等速力量。结果发现，许多 RG 受试者（83%）倾向于选择右腿进行跳跃，而许多 LG 受试者（87%）倾向于选择左腿进行单腿平衡。这表明熟练的运动在两个起跳腿组中都表现出右腿优势。在 LG 受试者中，左腿的脚底形状比右腿高。在 RG 受试者中，单腿垂直跳跃时右腿的数值高于左腿。然而，在起跳腿中并没有发现明显的优势。下肢可能不像上肢那样表现出明显的侧优势。
