Background. The evidence indicates that physical activity increases memory and ability to learn in human and animal. That is to say, the brain remarkably responds to exercise.

Objectives. The purpose of this study is to investigate the effect and comparison of anaerobic and aerobic exercise on memory.

Methods. In this study, ninety male students were randomly divided into three equal groups with 30 members. The first group did 3 aerobic exercise sessions (with using treadmill) of 60 minutes per week for 8 weeks. The second group were trained in anaerobic exercise (with treadmill), whereas the third one, the control group of non-exercising subjects, get involved in no intervention/interference. Afterwards, all of ninety students were asked to The IQ TEST lab to carry out a memory experiment both in the beginning and the end of programmed in order to evaluate their memory in the terms of Wechsler Test/ on the basis of Wechsler Test.

Results. The result of this study showed the memory change from Wechsler fragment tests/subtests before and after invention to the group with aerobic training (15.50 ± 5.41), with anaerobic training (17.00 ±4.89) and in the control group (2.13 ±1.96).The difference was significant (p<0.001) so that the variation of memory scores between aerobic and control group was (p<0.001). Also, anaerobic and control group was (p<0.001). And in other words, it had a significant difference.

Conclusion. The results will enable us to better comprehend the consequences that exercise can have on learning and memory. In general, the findings of the available research showed that the 8 weeks exercise of aerobic and anaerobic had high positive impact on the memory function of the students undergoing these experimental exercising subjects. We conclude that aerobic and anaerobic exercise probably can serve as a means to improve positively the memory's function so this kind of training is recommended for benefiting memory and learning process.

Background. 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.

Objectives. Therefore, the present article determines the effects of the different frequencies of whole-body vibration after a strenuous activity on blood lactic acid.

Methods. 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).

Results. 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.

Conclusion. 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.
