Abstract

The aim of this study was to analyze and compare differences in the peak torque, peak power, hamstring/quadriceps muscles ratio and range of motion between Turkey National Junior Team cyclists and triathletes. Seven triathletes (age 16.88±0.64 yr) and 8 cyclists (age 17.38±0.52 yr) were recruited to the study. Measurements of lower-extremity knee-joint movement were made with an isokinetic dynamometer at velocities 60 and 240°·s -1 . No significant differences were noted between the groups in the right hamstring and quadriceps at velocities of 60° . s -1 and 240° . s -1 . However, a significant difference was observed between the left limbs of the athletes at a velocity of 60° . s -1 in the hamstring PT, the hamstring average curve, the hamstring/quadriceps ratio and the hamstring/weight ratio. The cyclists exhibited higher differences compared to the triathletes in hamstring/weight, quadriceps/weight, hamstring peak torque, hamstring peak torque angle, hamstring average curve, hamstring peak power, hamstring average power, quadriceps peak torque and quadriceps average curve of the left limbs at a velocity of 240° . s -1 . The triathletes' left and right limb range of motion was significantly increased compared with the cyclists’ left and right limbs a t a velocity of 240° . s -1 . In conclusion, cyclists produced isokinetic strength at shorter hamstring and quadriceps muscle fiber lengths and larger peak torque angles compared with triathletes.
优秀少年铁人三项运动员与自行车运动员等速力量的比较分析
本研究的目的是分析和比较土耳其国家少年队自行车运动员和铁人三项运动员在峰值扭矩、峰值功率、腘绳肌/股四头肌比例和运动范围方面的差异。研究招募了7名铁人三项运动员(年龄16.88±0.64岁)和8名自行车运动员(年龄17.38±0.52岁)。用等速测功机在60°和240°·s-1速度下测量下肢膝关节运动。在速度为60°时,两组的右腘绳肌和股四头肌没有显著差异。s-1和240°。s-1。然而,在60°的速度下,观察到运动员的左臂之间存在显著差异。s-1在腘绳肌PT,腘绳肌腱平均曲线,腘筋/股四头肌比率和腘绳筋/体重比率。与铁人三项运动员相比,在速度为240°时,自行车运动员在左腿的腿筋/重量、股四头肌/重量、腿筋峰值扭矩、腿筋峰扭矩角、腿筋平均曲线、腿筋最大功率、腿筋总功率、股四肌峰值扭矩和股四头肌腱平均曲线方面表现出更高的差异。s-1。在240°的速度下,铁人三项运动员的左右肢体运动范围比骑自行车的左右肢体明显增加。s-1。总之,与铁人三项运动员相比,骑自行车的人在腿筋和股四头肌纤维长度较短、峰值扭矩角较大的情况下产生了等速力量。
