Changes of peak concentric extensor torque (CET) in CON, 26Hz of vibration frequency, and VF40. The peak concentric extensor torque (CET) was measured in isokinetic test. The change of CET after vibration was calculated based on postvibration measurement relative to previbration measurement in controls (CON), 26Hz of vibration frequency, and VF40. Data are expressed as means ± SEM. *P<.05, 26Hz of vibration frequency, and VF40 compared with CON by repeated-measures ANOVA with Bonferroni post hoc test. CON, control; VF26, vibration frequency of 26Hz; VF40, vibration frequency of 40Hz.

5. Fig 4
Changes of peak eccentric flexor torque (EFT) in CON, VF26, and VF40. The peak eccentric flexor torque (EFT) was measured by using the isokinetic test. The change of EFT after vibration was calculated based on postvibration measurement relative to previbration measurement in CON, VF26, and VF40. Data are expressed as means ± SEM. #P=.08, VF26 compared with CON by repeated-measures ANOVA with Bonferroni post hoc test. CON, control; VF26, vibration frequency of 26Hz; VF40, vibration frequency of 40Hz.
