Peak torque quadriceps

Peak torque values of quadriceps muscles relative to body weight were significantly higher in the national basketball team compared with basketball players from division I. No significant differences were found in peak torque values of quadriceps and hamstring muscles within the different basketball and soccer divisions.

Main outcome measures: Isokinetic hamstring and quadriceps peak torque and average power, and corresponding HQ ratios on a Cybex 340 isokinetic dynamometer. Results: In all isokinetic parameters measured, sedentary controls demonstrated significantly higher scores than subjects with DS and NDS. There was no significant difference between subjects with DS and NDS, although mean peak torque and …

In right (Rs) and left (Ls) extremity peak torque values, no significant difference was found between 60° and 180° sec -1 angular velocities (p>0.05). In peak torque values between PLs and NPLs, significant difference was found only in extension (Ex) phase at 60° sec -1 angular velocity p=0.001).

during the peak torque of quadriceps muscle under isometric condition. The EMG signal can be used as an indicator of the intensity of each contraction under iso-metric condition (Basmajian et al. 1972). To study the quadriceps using EMG, establishing a normalization protocol is necessary. According to Lin et al. (2008), EMG normalization is frequently used to improve reliability by decreasing …

Maximal peak torques of reciprocal knee flexion and extension were measured at each velocity to determine: 1) the mean maximal torque, 2) the torque ratio between the quadri- ceps and hamstring, 3) the torque difference between test speeds, 4) the torque difference between dominant and nondominant knees. 5) the torque ratio between the nondominant knee and dominant knee, and 6) the absolute …

Peak torque (in Newton meter [N·m]), body mass normalized peak torque (N·m·kg −1), and hamstring to quadriceps ratio (H:Q ratio) for dominant and nondominant legs were recorded.

The purpose of this study was to determine the dominant leg’s peak isokinetic torque production of male college athletes. One hundred subjects, from 18 to 25 years of age, were tested on a Biodex 8-2000 isokinetic dynamometer concentrically at 60, 120,300, and 450 “Isec and eccentrically at 60 and 120 “Isec. All data were analyzed by means of a repeated measures analysis of variance to …

One such measure is the hamstrings-to-quadriceps ratio (H/Q ratio), calculated as the peak torque of the hamstrings divided by the peak torque of the quadriceps within the same limb (Eq. (2.1)): (2.1) As stated before, isokinetic peak torque is often assessed using concentric contractions.
