Introduction: Colon cancer or colorectal cancer is the growth of cancerous masses in the colon. According to research evidence, the use of antioxidants and regular exercise are the best ways to prevent and treat many diseases. This study aimed to investigate the effect of eight weeks of intermittent exercise and Quercetin consumption on the brain-derived neurogenic factor (BDNF) and cyclic-adenosine monophosphate responsive element-binding protein (CREB) in the brain hippocampus of rats with colon cancer which has many influences on cognitive functions.Methods: The subjects of this study included 50 male Wistar rats (weight: 250±30 grams, age: 12 weeks) which were homogenized by weight and were randomly divided into five Healthy Control, Cancer Control, Cancer + Quercetin supplement, Cancer + Intermittent exercise, Cancer + Quercetin supplement + Intermittent exercise groups (10 rats in each group). BDNF and CREB measurements were performed in the rats’ hippocampus according to the ELISA standards and method. SPSS software was used for data analysis.Results: The results showed that eight weeks of intermittent exercises had a significant effect on the mean score of BDNF (p = 0.047) and CREB (p = 0.032) in rats’ hippocampus with colon cancer. Eight weeks of Quercetin supplementation had no significant effect on the mean BDNF score (p = 0.792) and the mean CREB score (p = 0.363) in rats’ hippocampus with colon cancer Conclusion: In general, the findings showed that intermittent exercise and Quercetin supplementation improve BDNF and CREB in the hippocampus of rats with colon cancer.

The purpose of this study was to investigate the effect of a course of aerobic exercise and vitamin D supplementation on the psychomotor function of elderly women with sleep disorders. Based on this, 42 people were selected in an accessible and targeted manner with an age range of 60-70 years. They all suffered from insomnia. Subjects were randomly divided into four groups: aerobic exercise, aerobic exercise-vitamin D supplement, vitamin D supplement and control group. Vitamin D intake in both groups was taken as 2000 units daily. The Physical Activity Readiness Diagnostic Questionnaire (PARQ) was used to know the level of physical fitness of the subjects and the Gibson 24-hour diet recall questionnaire the day before the pre-test and post-test. The Pittsburgh Sleep Quality Scale was used to extract the sleep profile. COG psychomotor test was also used to assess cognitive and mental components and information processing. The results showed that the aerobic, supplement and aerobic-supplement groups had a significant improvement in selective attention and reaction time. Also, the aerobic-supplement group had a significant improvement in selective attention and reaction time compared to the aerobic group and the supplement group. Aerobic exercise along with vitamin D supplementation seems to improve the motor and motor function of older women. Therefore, vitamin D supplementation and aerobic exercise in interaction are recommended for older women.

Neonatal growth indices are one of the important issues in the assessmentand care of pregnancy which have significant effects on the life after birth.Therefore, it is important to recognize their related factors. The aim of thisstudy was to investigate the relationship between pregnant women's lifestyleand physical growth indices in newborns. This descriptive-comparativestudy was conducted on 412 pregnant women (mean age 28.1±5.6 years)who referred to Mahdieh Hospital in Tehran by a cross-sectional and fieldmethod. Subjects were selected by convenience sampling method. Data werecollected and recorded by Lifestyle Questionnaire (LSQ) and informationabout the growth indices of newborns from their medical records in TehranMahdieh Hospital. Then, growth indices were compared with NCHSstandard norm (P≤0.05). Independent and one-sample t tests and Pearsoncorrelation were used to analyze the data. According to the results, thequality of lifestyle in pregnant women was reported to be moderate. Also, acomparison of weight and height indices showed a significant difference inthe time intervals after birth in comparison with the NCHS norm (P≤0.05)which indicated that this norm was lower than the global norm in Iranianinfants. On the other hand, no significant difference was observed in thehead circumference (P=0.18). Considering the findings of this study onlifestyle and moderate physical activity in pregnant women, mothers arerecommended to have more physical activity and to improve their nutritionalquality so that they can promote their lifestyle and thereby improve thegrowth indices of newborns.

Autism is one of the major developmental disabilities which make visual imbalance for those who are vulnerable. Research has shown that vision has a key role in all those activities which focus on aiming task. The aim of this study was to investigate the visual focus on improvement of a throwing task of autistic children. 24 boys at the age of 10 were randomly assigned into two experimental and control groups. Independent t-test and ANVA were used to analyze the data. The results suggested that there was a significant difference between pretest scores in acquisition (p≤0.05). On the other hand, the in experimental group had a better performance in retention phase. . The results suggested that there was a significant difference between pretest scores in acquisition (p≤0.05). On the other hand, the experimental group had a better performance in retention phase. It was concluded that visual affects the throwing task.

The aim of this study was to investigate the effect of neurofeedback training on sleep quality and psychological skills of athletes with psychophysiological approach. The research method was semi-experimental and application with pretest and posttest design and a control group. 31 athletes who were members of a sport team gained the criteria to enter the study. They were randomly assigned to experimental and control groups and the experimental group received neurofeedback treatment. The neurofeedback training lasted 3 sessions a week, 45 min. each session for 2 months. This protocol was performed in a bipolar manner at C4-CZ points. Pittsburgh Sleep Quality Index (PSQI) was used to extract sleep quality profile and OMSAT-3 and Elisa method were used to assess psychophysiological stress of participants. Covariance analysis and dependent t test were used to analyze the data. The results suggested that neurofeedback training can influence to balance stress and to improve sleep quality of athletes which greatly affects their performance.

Locomotion fundamental skills play an essential role in improving motor development throughout the life span as they provide children with better development by enhancing search abilities in environment. This study aimed at comparing the locomotion fundamental skills in 7-year-old children with lower extremity deformities and healthy children. The statistical population consisted of 7-year-old male students with lower extremity deformities in Qazvin city. After a list of schools was prepared, some schools were randomly selected. Then, 96 subjects with lower extremity deformities (flat foot, genu valgum and genu varum) were identified in a primary screening. To evaluate knee alignment, varrum and valgus, a caliper with accuracy of 1.1 mm was used. To measure foot curve, CSI method was used. To analyze the locomotion skills, Ulrich test of gross motor development (second edition) was applied. The results showed no significant differences between flat foot and genu varum groups and control group in fundamental skills (P>0.05). Significant differences were found between genu valgum group and control group in locomotion fundamental skills (P<0.05). The results showed that genu valgum deformity can have a negative effect on children's performance in locomotion skills and also disrupt the natural alignment of the lower extremities.

The purpose of this study is to investigate the effect of physical activity onmemory and dynamic balance of elder people. Subjects (n=15) were selected asvolunteers. The intervention was performed in an eighteen session period, threetimes a week (each session, 45 minutes). Yoga training was performed for mentalrelaxation. Wexler test was performed for memory evaluation. Seat up test wasused to test the dynamic balance. The results suggested that water-based exercisesand Yoga protocol have had a positive significant effect on memory (p=0.03) anddynamic balance. It was concluded that a selected physical activity program,especially water-based exercises has less potential for making people injured.
