The effect of whole body vibration on isokinetic torque parameters of ankle muscles during running before and after fatigue in age groups during growth and adults

flat foot is a disorder that reduces performance in people with different age groups. One of the new treatments is whole-body vibration. The main question is whether there is a significant difference according to the isokinetic muscle strength after whole body vibration intervention in different ages of growth and adults.

64 people with flexible flat feet were included in the study. People were divided into 4 intervention and control groups based on the age groups of growth and post-growth age. Then, in the intervention groups, 10 sessions of whole body vibration were applied 3 sessions per week in a standing position. In all participants, the isokinetic torque of the invertor and evertor muscles at angular velocities of 30 and 120 degrees/s were evaluated before and after the vibration intervention in two stages before and after applying general fatigue.

The results showed that before applying the whole-body vibration intervention, there was no significant difference between the control and intervention groups according to the maximum isokinetic torque parameter (P>0.05). The effect of fatigue parameter and angular velocity of isokinetic torque on the inverter and inverter muscle torque was significant (P<0.05). The isokinetic torque of the invertor and evertor muscles at both angles of 30 and 120 degrees after applying 10 sessions of whole-body vibration showed a significant improvement compared with before the intervention in both with and without fatigue (P<0.05).

This study showed that whole-body vibration can be effective as a relatively new modality in reducing the effects of fatigue during running and increasing the strength of ankle muscles in two age groups during growth and adulthood.
