year 5, Issue 1 (Special Issues 2017)
Abstract

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.

Abstract

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.

Abstract
Background. Body adaptations and the high level of achievement in different sporting fields depend on the degree of fitness and training. Hence, it is important for basketball players to have suitable body fitness for tactics and skill performance.
Objectives. The present study aims to investigate the effect of selective plyometric exercises using an unstable surface on the movement performance of female basketball players.
Methods. In this pre-/post-designed clinical trial, the subjects were selected from among qualified female basketball players (n=24) having a history of two-year regular specialized training in a team considered as elite. They were randomly assigned into two, experiment (age: 20.25±2.34, training history: 2.55±0.29, and BMI: 23.28±0.93) and control (age: 21.16±2.79, training history: 2.60±0.75, and BMI: 24.80±1.04) groups. The experiment group performed for eight weeks (three sessions each week with a duration of 80 min/session) progressive plyometric exercises on an unstable surface. The assessment of dependent variables was performed using functional movement screening and the star excursion balance test. The results of the control and experiment groups were compared using multivariate covariance and post hoc Bonferroni test, while the pre- and post-test results were compared using the dependent t-test at a significance level of (p<0.05).
Results. Comparing the results between the groups through the functional movement screening test and dynamic balance showed a significant difference. An improvement was seen in the results of relevant tests for the experiment group (p<0.001).
Conclusion. The use of progressive plyometric exercise on an unstable surface shows an improvement in the results of the functional movement screening test and movement performance. This, in turn, results in an improvement in exercise performance.

Abstract
Background. Parkinson’s disease (PD) is characterized by motor and non-motor symptoms that affect patients’ functional performances, especially while performing dual tasks which is a critical factor in connection with everyday living. There are many controversies about the benefits.
Objectives. This study assessed the efficacy of motor and cognitive dual-task training programs for improving of balance, quality of life, and fear of falls in people with idiopathic Parkinson’s disease.
Methods. About 30 PD patients (Hoehn and Yahr stage II-III while ON medication) were assigned to a cognitive dual-task training group (n = 10), a motor dual-task training group (n = 10), or a single task control group (n = 10). All groups received 30 sessions of different exercises for ten consecutive weeks. Balance, quality of life, and fear of falls respectively assessed with Time Up and Go Test (TUG) and Trial Walk Test (TWT), Parkinson’s Disease Questionnaire - 39 (PDQ - 39), and FES-I, before and after training and after one-month follow-up.
Results. No significant time by group interaction were found, suggesting both dual-task and single-task training had a similar effect on outcome measures (P > 0.05). A significant post-training improvement in TUG (F = 535.54, p < 0.001), PDQ - 39 (F = 463.52, p < 0.001), TWT (F = 284.89, p < 0.001), and FES-I (F = 266.4, p < 0.001) was found after single and dual-task training. These improvements were maintained at follow-up, although the effect was slightly reduced (p < 0.05).
Conclusion. Motor/cognitive dual-task training and single-task training were found to be moderately effective in improvement of balance, quality of life, and decrease of fear of falls in people with PD.

Abstract
Background. Low back pain is a significant issue in the field of health. Therefore, addressing new therapeutic approaches seems necessary.
Objectives. The present study examined the effect of combining core stability with stretching exercises on pain intensity and motor function in people with chronic nonspecific low back pain with and without hyperlordosis.
Methods. The research method was quasi-experimental, and its statistical population included adolescent girls with chronic low back pain with and without lumbar hyperlordosis in Lahijan schools (2018). Sixty qualified girls aged 12 to 15 years were purposefully selected based on inclusion and exclusion criteria and were randomly divided into four groups. Experimental groups with and without lordosis performed stretching-core stability exercises for eight weeks in three 45-minute sessions. At the beginning and end of the exercise period, the dependent variables were evaluated.
Results. Students with and without lumbar arch enlargement who underwent therapeutic exercise experienced significant pain relief and lumbar arch reduction. Lumbar muscle strength was also increased compared to the control group (p = 0.001). However, there was a significant difference in static and dynamic balance variables between experimental and control groups without lordosis. Results also showed the effect of exercises in all variables between pre-test and post-test of the two experimental groups (p = 0.001).
Conclusion. Combining core stability with stretching exercises can, in addition to improving chronic low back pain, reduce the severity of lumbar lordosis and the trunk muscle endurance and its balance.
