Acute effects of partial-body vibration in sitting position

Figure 1 Placement of the electrodes according to SENIAM[27].

Figure 2 Sitting position on the vibration platform. HRV: Heart rate variability; EMG: Electromyography.

Figure 3 Flowchart of the procedure. EMG: Electromyography, muscular activation of the lower back muscle erector spinae (ES); HRV: Heart rate variability was measured with Polar V800. Balance was measured using the modified star excursion balance test (mSEBT) and expressed in centimeter; Flexibility was assessed with the fingertip-to-floor method (mFTF) and measured in centimeter.
