• Resumen

  • The aim ofthis 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 hamstringPT, 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 torqueand quadriceps average curveof the left limbs at a velocity of 240°.s-1. The triathletes'left and right limb range of motion was significantly increased compared withthe cyclists’ left and right limbs at 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.
