 Physical activity based on intensity and duration could have an effective impact on cognitive status. Moreover, using the herbal supplement along with exercise training regulates the secretion of pre-inflammatory cytokines, and has a positive impact on the cognitive status.  The aim of this study was to examine the effect of 12 weeks aerobic exercise and saffron supplement consumption on cognitive condition and serum levels of IL-1β and TNF-α in elderly men.

Forty men with average age of 68.12±2.99 years and body mass index of 25.77±1.2 kg/m2 were purposefully selected and randomly divided into four equal groups (n=10) including aerobic exercise, saffron, aerobic exercise+saffron and placebo. The interventions were conducted for 12 weeks. Aerobic exercise included 8 minutes running up to 75-85 percent of maximal reserve heart rate were performed in the first session. In every two sessions, one minute was added to the running time, so that after 12 weeks, the running time reached to 26 minutes. Saffron supplement was taken daily in the form of capsules with a dose of 200 mg. Measurement of IL-1β and TNF-α were done using Elisa method. Cognitive status was measured by MMSE questionnaire. Data were analyzed by mixed design analysis of variance and Tukey post hoc test at the significant level of p<0.05.

Serum levels of IL-1β and TNF-α in three intervention groups decreased significantly; but it indicated higher changes after exercise+saffron intervention (p<0.05). Moreover, cognitive status improved significantly in the intervention groups than placebo group; so that this improvement was higher in the exercise+saffron group (p<0.05).

 Consuming saffron supplements along with aerobic exercise, at least for 12 weeks, is associated with improving cognitive status and reducing inflammatory factors in the elderly; these changes probably prevent cognitive disorders and Alzheimer’s disease in old age.

The aim of this study was to investigation of the effect of 12 weeks aerobic training and consumption of olibanum extract on cognitive status and BDNF levels in the elderly with mild cognitive impairment (MCI).

32 elderly people who scored between 21 and 25 in the MMSE questionnaire were purposefully selected and randomly divided into 4 groups: aerobic training, olibanum, aerobic training + olibanum, and placebo (N=8 in each group). Interventions were performed for 12 weeks. Aerobic training consisted of eight minutes of running with an intensity of 75 to 85% of the maximum reserve heart rate in the first session. Both sessions increased running time by one minute until after 12 weeks, the running time reached 26 minutes. Olibanum extract was taken as a capsule at a dose of 100 mg/kg body weight per day.

BDNF levels in both training and training + olibanum groups increased significantly compared to the other two groups (P <0.05). Cognitive status also increased significantly in the three groups of intervention compared with the placebo group (P <0.05).

It is possible that 12 weeks of aerobic training and olibanum can slow and possibly stop the progression of MCI by improving the cognitive status in the elderly with MCI.

The aim of this study was to investigate the effect of 12 weeks of aerobic training and consumption of artichoke extract on blood glucose and insulin resistance and its relationship with the cognitive status in elderly with mild cognitive impairment (MCI).

40 elderly people who obtained a score between 21 and 25 from the MMSE questionnaire were randomly selected, and randomly divided into 4 groups: aerobic training, artichoke, aerobic training + artichoke, and placebo (each group 10 People) were placed. The interventions were performed for 12 weeks. The aerobic training consisted of eight minutes of running with intensity of 75 to 85% of the maximum stored heart rate in the first session. After two sessions added one minute to the running time, so that after 12 weeks, the running time reached 26 minutes. Artichoke extract was taken in capsules at a dose of 300 mg / kg body weight per day.

Blood glucose and insulin resistance decreased significantly in two groups of training and training + artichokes (P <0.05). Cognitive status increased significantly in the three intervention groups compared with the placebo group, which was higher in the training + artichoke group (P <0.05). As cognitive status increased, blood glucose and insulin resistance decreased (P <0.05).

Consumption of artichoke extract along with aerobic training for 12 weeks can possibly slow the progressive course of mild cognitive impairment and may stop and prevent the onset of diabetes due to this disorder.

The aim of this study was to determine the effect of Tai Chi training on TNF-α, BDNF serum levels and cognitive and physical function in women with stroke.

20 women in Qom city with stroke (mean age: 65.80±3.55y, weight: 68.41±14.00 kg and body mass index: 26.33± 5.15kg.m2) voluntarily were divided randomly into Tai Chi group (10 patients) and control group (10 patients). Serum BDNF and TNF-α were analyzed by using an ELISA kits in pretest and post-test. Cognitive function were assessed by the Mini- Mental State Examination (MMSE). Also pretest and post-test measurements were recorded for the timed upand- go test. Tai Chi group trained 6 weeks, three times per week for 60 minutes (consisted of a 10-minutes warm-up period, 40-minutes simplified Tai Chi exercises performed, and a 10- minutes cool-down period). Data were analyzed using the independent samples t-test and paired samples t-test.

Tai Chi group showed a significant improvement in serum TNF-α and dynamic balance (p≤0.05). Despite the increase in serum BDNF and improvement cognitive function, no significant differences were observed between the two groups.

Therefore the findings of this study suggest that Tai Chi training as a low intensity and simple training can improve women balance and inflammatory status with stroke.

Reviewing memories in a Verbal or non-verbal ways is a type of interpersonal communication that elderlies or patients with cognitive disorders by expressing their feelings find an opportunity for social and professional interactions. The purpose of this study is analyzing the effectiveness of treatment techniques of life revision on cognitive status of retired men in Tehran.
The population of this research contains retired men who are going to Buali Park in Tehran. Among these people, we selected 30 of them who were interested in participating in the study and their adjustment score were average and low, they were randomly selected and divided into experimental and control groups (each group 15 members). Both groups answered the MMSE criteria before and after the training course.
Covariance analysis showed that there is a significant difference between mean of experimental and control groups. Therefore the method of treatment techniques of life revision on cognitive status of retired men in Tehran was effective.
Life revision is a treatment process that helps retired people to reflect their events and experiences in the past with pleasure and joy and reach to a mental stability.

Cognitive performance such as prediction and reaction time changes along with aging. It seems that regular lifetime physical activity depends on the delay of these factors. This study aimed at investigating the effect of Pilates training on the improvement of motor performance of sedentary elderly men in Kermanshah city. 40 sedentary elderly men (mean age 72. 15 ± 6. 54 years) were selected from the senior citizen centers in Kermanshah and were divided into two groups of experimental and control randomly. The experimental group performed Pilates protocol for 8 weeks. Both groups participated in the pretest and posttest of cognitive performance. The data obtained from the pretest and posttest were analyzed by paired samples t test and independent t test was used to compare the posttests of both groups. The results showed that Pilates group outperformed the control group significantly in their cognitive status and reaction time in the posttest (P˂0. 05)، but there was no significant difference in prediction between these two groups. The patterns of these results suggested that Pilates exercises could improve the elderly''s cognitive performance.
