Table 2. Summary data for dependent variables (RF and VL reflex latency, RF and VL EMD, isokinetic peak torque of knee extensors). Intervention group (n = 10) received 3 minutes WBV, whereas the control group (n = 12) assumed the same position on the WBV platform with no vibration. pre-measures were collected prior to the intervention; post-measures collected immediately following the treatment. Data are means (┬▒standard deviation).
