Table 2: Statistical analysis of maximum knee flexion and extension strength at different measurement velocities (30\({}^{\circ}\)/s, 120\({}^{\circ}\)/s, and 240\({}^{\circ}\)/s) in both placement positions (anterior and posterior aspects—AA and PA, respectively). Results are expressed in Newtons (N). strength increased when the pad was placed in the AA position, but no differences were detected with the pad positioned in the PA. Comparisons with other studies regarding the strength data cannot be made. They would be methodologically incorrect because the lengths of the lever arm were not reported (in the present study, they are 30 cm), which would be methodologically incorrect. The force generated has a positive correlation with respect to the lever arm length; when one of the two variables increases, the other also increases [15]. Therefore, we focused on the H/Q ratios that were not influenced by the lever arm length. In the study by [PERSON] et al. [2], at low velocities (60\({}^{\circ}\)/s) the authors obtained a mean force ratio of 0.54 \(\pm\) 0.07. In our study, at low velocities (30\({}^{\circ}\)/s), the mean force ratio was very similar (0.54 \(\pm\) 0.14) at the AA position but significantly higher at the PA position (0.62 \(\pm\) 0.12). At medium velocities (180\({}^{\circ}\)/s) in the study described above, an average H/Q ratio of 0.57 \(\pm\) 0.09 was obtained, which is relatively lower than that obtained in our study at 120\({}^{\circ}\)/s, where a value for the H/Q ratio at the AA position of 0.75 \(\pm\) 0.22 was obtained, with no significant differences with the PA position (0.80 \(\pm\) 0.19). The same occurs at high velocities (240\({}^{\circ}\)/s) where a mean H/Q ratio of 0.62 \(\pm\) 0.09 was obtained, much lower than that obtained in our study, as well as 0.84 \(\pm\) 0.2 in the AA and 0.89 \(\pm\) 0.17 in the PA with no significant differences between the two positions. It should be noted that in that study, professional female soccer players were measured, and professional male and female basketball players were measured in the present study.
