AIM To investigate the acute effects of sinusoidal and stochastic resonance partial-body vibration in sitting position, including muscle activity, heart rate variability, balance and *** Fifty healthy participants were assigned randomly to two training conditions: A sinusoidal partial-body vibration(SIN, 8 Hz) or a stochastic resonance partial-body vibration(STOCH, 8 ± 2 Hz). For baseline assessment participants sat on the vibration platform without vibration. Both training conditions consisted of five series of a one-minute vibration training and a one-minutebreak between them. In this experimental study surface electromyography(EMG) of the erector spinae(ES), one of the back muscles, and heart rate variability(HRV) was measured at baseline and during training. Balance and flexibility were assessed at baseline and immediately after training. Balance was measured with the modified star excursion balance test(mS EBT) and flexibility was assessed through the modified fingertip-to-floor method(mF TF).RESULTS Paired sample t-test showed a significant increase in balance that was restricted to STOCH(t =-2.22, P = 0.018; SIN: t =-0.09, P = 0.466). An increase in flexibility was also restricted to STOCH(t = 2.65, P = 0.007; SIN: t = 1.41, P = 0.086). There was no significant change of muscle activity in the ES-EMG in STOCH or SIN conditions. In both training conditions, HRV decreased significantly, but remained in a low-load range(STOCH: t = 2.89, P = 0.004; SIN: t = 2.55, P = 0.009).CONCLUSION In sitting position, stochastic resonance partial-body vibration can improve balance and flexibility while cardiovascular load is low. STOCH can be a valuable training option to people who are unable to stand(e.g., people, who are temporarily wheelchair-bound).
