The relation of leg preference and muscular strength in elite fencers was examined. The dominant and nondominant extensor and flexor muscles of 30 elite fencers (M age = 18.2 yr., SD = 2.0 yr.; M height = 173 cm, SD=7.4 cm; M weight = 62.7 kg, SD=8.9 kg), who were members of the Greek national team, and 14 healthy, young, sedentary adults (8 men, 6 women; M age 23.4 yr., SD = 1.9; M height = 169 cm, SD = 10.5 cm; M weight = 66.3 kg, SD = 9.9) were tested for concentric isokinetic contraction at slow (30 to 60 degrees/sec.) and fast (240 degrees/sec.) angular velocities. Significant multivariate differences were found between groups for knee extension, angle of knee extension, knee flexion, and flexor/extensor peak torque ratio. In contrast, no significant difference was found between the dominant and nondominant legs. There was no significant difference in the flexor/extensor peak torque ratio among any of the concentric angular velocities tested. These findings suggest that long-term training in fencing influences the strength characteristics of the lower limbs.
研究了优秀击剑运动员的腿偏好与肌肉力量之间的关系。对30名希腊国家队的优秀击剑运动员（年龄中位数 = 18.2岁，标准差 = 2.0岁；身高中位数 = 173厘米，标准差 = 7.4厘米；体重中位数 = 62.7千克，标准差 = 8.9千克）以及14名健康、年轻、久坐不动的成年人（8名男性，6名女性；年龄中位数23.4岁，标准差 = 1.9；身高中位数 = 169厘米，标准差 = 10.5厘米；体重中位数 = 66.3千克，标准差 = 9.9）的优势腿和非优势腿的伸肌和屈肌进行了慢速（30至60度/秒）和快速（240度/秒）角速度的等速向心收缩测试。在膝关节伸展、膝关节伸展角度、膝关节屈曲以及屈肌/伸肌峰值扭矩比方面，两组之间存在显著的多变量差异。相比之下，优势腿和非优势腿之间未发现显著差异。在所测试的任何等速角速度下，屈肌/伸肌峰值扭矩比均无显著差异。这些发现表明，长期的击剑训练会影响下肢的力量特征。
