The objective of this study was to assess leg muscle activities during whole body vibration (WBV)
training with various squat position exercises.
Subjects performed four different squat exercises on a vibration platform (VM-10, Sonicworld Co.) Ten healthy women volunteers (age 21±1.3 years, height 160±2.1 cm, weight 52±4.6 kg) were selected. EMG signals four leg muscles were taken and analyzed.
The exercises were performed both with 10 seconds WBV and without 10 seconds WBV. Muscle activities during WBV were compared with non-vibration stimulus.
In the result, EMG signals caused by WBV were significantly higher (P<0.05) compared with non-vibration stimulus in all leg muscles and squat exercises.
The increase in muscle activity caused by Whole body vibration was significantly higher (P<0.05) in LS and OS compared with HU&HS.
