<p dir="ltr" style="text-align: justify;"><span style="font-size:12px;"><span style="font-family:times new roman;"><strong>Background. </strong>Fatigue has an undesirable effect on the continued exercise performance and decreases athlete's activity. Fast lactic acid disposed is high of importance for athletes. </span></span></p>
<p dir="ltr" style="text-align: justify;"><span style="font-size:12px;"><span style="font-family:times new roman;"><strong>Objectives. </strong>Therefore, the present article determines the effects of the different frequencies of whole-body vibration after a strenuous activity on blood lactic acid. </span></span></p>
<p dir="ltr" style="text-align: justify;"><span style="font-size:12px;"><span style="font-family:times new roman;"><strong>Methods. </strong>60 athletes were chosen from selected athletes of provincial championship through bruce test. The athletes randomly were divided into four groups of 15 participating in the initial recovery scheme after strenuous exercise (Cunningham test). The first group did initial passive/ inactive recovery that the subjects sat on a chair after exercise and the second to fourth did initial 15 minutes active retrieval on the vibration platform at different rate /with different speed. Their blood lactic acid was checked in three phases by manual lactometer (before activity, immediately after the activity, 15 minutes recovery period the initial situation). </span></span></p>
<p dir="ltr" style="text-align: justify;"><span style="font-size:12px;"><span style="font-family:times new roman;"><strong>Results. </strong>The result of this research indicated that the average level of lactic acid immediately after activity to before activity among 4 groups was significantly different (P=0.006). decrease in lactic acid 15 minutes after the initial state recovery to immediately after that, was significant in all groups (p<0/001). In initial recovery with 20 HZ WBV at amplitude of 5mm lactic acid repelling excretion was the most. </span></span></p>
<p dir="ltr" style="text-align: justify;"><span style="font-size:12px;"><span style="font-family:times new roman;"><strong>Conclusion. </strong>In general, it is showed that to excrete the lactic acid after exhausting and intense activity active initial state recovery scheme with whole- body vibration (WBV) at 20 HZ and on amplitude of 5 mm had much more useful effects on reducing lactic acid after exhausting and intense activities than other schemes. Hence, active initial recovery with whole – body vibration at mentioned rate is recommended to remove immediately the lactic acid from the body after intense anaerobic exercise.</span></span></p>
