The purpose of this study was to compare physical fitness and mental health factors among active, non active and mountaineer aged people. To do this, Forty three elderly men (mean age 57.7±9.3, height 168.5±12.5 and weight77.3±21.1) were selected randomly through questionnaires in the North of Tehran. According to their activeness and type of activity, subjects were divided into three groups of Mountaineer (n: 15), active (n: 14) and Non-active (n:14).Then, General Health Questionnaire Goldberg (GHQ) was administered and their cardiovascular and physical and motor fitness factors consist of: Body Fat percent, Blood pressure, Heart Rate, BMIR eaction time, modify balk test were measured. Physiological data were analyzed using one way ANOVA, and General Health Questionnaire Goldberg data were analyzed using multivariate analysis of variance (MANOVA). The results showed that there was significant difference between average of aerobic capacity in three groups (P£0.01) and the mountaineer group had better aerobic capacity. Also there was significant difference among groups in scores of somatic symptom, anxiety, social performance, severe depression domains and the average in General Health. In other words, the average of General Health in mountaineer group were better than the other group (p£0.05). Therefore according to this results, it is recommend that older peoples should participate in regular physical activities to increase length life and improve mental health, also they must be have regular Mountaineering at their physical activities program.

The purpose of this study was to evaluate the performance of judokas with different aerobic and anaerobic power in special judo fitness test. For this purpose, 33 Judoka men in Kermanshah were selected with at least three years of experience in this field and regular practice and participation in official competitions; and the sampling in this study were available (age: 22.60±2.25year, weight:72.5±5.5 kg, height: 175.4±5.6 cm). The instruments used in this study were special judo fitness test, cycle ergo-meter for 30 sec Wingate anaerobic test and treadmill for Bruce maximal aerobic test. In order to avoid the effects of fatigue tests on each test, between each test, there was three days off. Therefore, for data analysis, we used parametric tests. To assess differences between the two groups, high and low aerobic and anaerobic power test was used for Judo, as well as the Pearson correlation coefficient in order to examine the relationship between aerobic and anaerobic capacities with special judo fitness test. The results showed that between the two groups with high and down aerobic power there is a significant difference in the performance of Judo test (p£0.05). In addition individuals with higher aerobic power showed a better performance. But, the results of comparison between the judokas anaerobic power up and down showed that the two group had no significantly difference in the performance of Judo test (p³0.05). Also, the results showed that there is a correlation with a high significant level between aerobic power (VO2max) and special judo fitness test (p£0.01). However, there is no significant relationship between anaerobic power (peak power) and special judo fitness test (p³0.05). So, this study suggests that that Judokas with higher aerobic power had better performance in judo test.

Among four characteristics of exercise; that is, type, time, frequency and intensity of exercise, it is clear that changing the intensity of exercise can make different compatibility. The present study tries to determine and compare the effect of ten weeks exercise program, three different exercise intensity with same exercise volume on lower limb’s bio-motor abilities in women between 25-35 years old. For this reason, 45 women with this condition divided to three groups with ten people randomly. These groups divided to exercise with intensity of 90-95%, 95-100% and 100-105% with one maximum repetition. Exercise carried out based on increasing overload principle and step loading through the period and flat pyramid in one session and for three days in week and 90 min each session. Biomotor abilities factors of muscular strength (power of one maximum repetition) muscular endurance (number of repetition with weights, 70% of one maximum repetition), speed (test of 45 meter speed), and muscular power (test of vertical hump height) in lower limb of women are compared before and after ten week of evaluation of exercise. The results showed that each of the exercise intensities have significant effects on strength, endurance, speed and power of women’s lower limbs. With the exception of power, there is significant difference among the effects of three intensities so that intensity of 100 to 105% of one maximum repetition makes the most changes.

The aim of this study is to investigate the effect of eight weeks of resistance training on 17-18-year-old boys’ interleukin-10, lymphocytes, monocytes and macrophages. 24 of 16-18-year-old boys of Jalil Falahi High School of Marvdasht were selected voluntarily and based on research needed conditions with the mean age of 0.92 ±16.91 years, mean weight of 5.05 ± 74.19 kg and height of 5.04 ± 170.40 cm. They were randomly divided into two groups: resistance training and control. Training group was exposed to resistance training for eight weeks (three days per week) with an intensity of 60 to 75% of one repetition maximum. In each session, eight exercise stations were used and each station movements were run in three turns. Before and after these eight weeks of training, all subjects gave blood (5 ml) when they were fasted. To analyze the research findings, independent Ttest and dependent T-test were used (p£0.05). Results showed that eight weeks of resistance training lead to significant increase in interleukin10 (p= 0.04), a significant reduction in lymphocytes (p=0.02), decreased monocyte (p=0.11) and macrophages (p= 0.09). Conclusion: Resistance training for eight weeks can have beneficial effects on some inflammatory markers and cause reduction in the risk of cardiovascular events.

Introduction: Hypertension associated with type 2 diabetes and always have seen in most patients with type 2 diabetes. The aim of this study was to investigate the effect of aerobic training on blood pressure in type 2 diabetic women. Methods: 32 type 2 diabetic patients with hypertension were randomly divided into two groups: aerobic sport group (n=16) and control group (no exercise) (n=16). Subjects were done aerobic exercise 3 days per week, each session lasting 45 to 60 minutes. Hypertensive subjects before and after aerobic training were measured. Results: No significant difference in blood parameters of systolic, diastolic and pulse rate were observed statistically between the two groups. Independent t-test showed that the posttest between the two groups in systolic blood pressure (p<0.000) and diastolic (p<0.009), there was a significant difference between the two groups in heart rate (p<0.224) difference significant. However, paired t-test showed that systolic blood pressure (p<0.000) and diastolic (p<0.003) and heart rate (p<0.000) decreased significantly in aerobic training group. Diastolic blood pressure was significantly increased only in the control group (p<0.003). Conclusion: According to the results aerobic training may reduce blood pressure in type 2 diabetes women with hypertension, it is recommended that aerobic training associated with the drug therapy may be prescribed to type 2 diabetes women to help control the disease.

Background: With regard to the development of urban life and the daily movement patterns, the decrease in motor activity, especially among women, affecting their organs and muscles and puts serious physical inactivity and weaknesses. To prevent or deal with the problem of creating attractions for all the sports facilities among women in this field is a powerful tool. The aim of this study was Comparison of some indicators of evaluating the performance of nerve - muscle elderly women participating in an exercise in the morning. Methodology: This was a reason- comparative (after the occurrence) research. 40 active elderly women (age 64 years, height 160 cm, weight 73kg) that regularly participated in morning exercise in previous year (5 days per week), and 8 sedentary elderly women (age 66 years, height 162cm, weight 77 kg) that have not experience of any regular physical activity, participated in this study. Timed Up & Go (TUG) and 5-Chair stand (5CS) tests, were used for evaluation of neuromuscular system function. Independent T-Test (P£0.05) used for determination of differences of TUG and 5CS scores between groups. Results: Statically analyses showed that there was significant different in 5CS and TUG scores in elderly men that participated in morning exercise and sedentary elderly women. Conclusion: The results of this study showed that there was significant different in neuromuscular system function between older people that regularly participated in morning exercise and sedentary older people. According to the results of this study it seems regular participating in morning exercise causes improvement of neuromuscular system function in active older people comparison to sedentary older people. Possibility, this issue can prevents from many neuromuscular-related dysfunctions in older adults.

The purpose of this study was to examine the effect of a pilates training program on static and dynamic balance the girls with hearing disabilities. Therefore were selected 16 girls 13 to 16 years of hearing disabilities (Deaf: 14.12±1.12 Year; Hard of hearing: 14.25±1.03 Year; Height of hearing: 145±5.75cm; height of the Deaf: 145.25±5.67) be available for this study and were divided in two training groups Eight persons, deaf and hard of hearing. Before performing the exercise protocol a static balance was assessed subjects by balance test stork and dynamic balance by Y balance test. The Groups performed pilates exercises for six weeks and three sessions per week (60 minutes per session). Were used of statistical tests paired t and independent t in order to analyze the data. t-test results showed significant difference the deaf and hard of hearing between the pre-test and post-test results static and dynamic balance (p£0.05). While the not found significant difference between effects of Pilates on the static and dynamic balance hard of hearing and deaf girls. The results of this study can be said the Pilates exercises leads to improving balance in persons with hearing disabilities; so that is applied to achieve different goals such as improve athletic performance, improve damage, improve health and fitness. Therefore professionals and physical education teachers hearing Handicapped; can benefit from it in addition to other training methods considering the effects of the exercises in the field of pathology and rehabilitation and improve performance.

Background: Hypoxia can cause beneficial physiological adaptations. The aim of this study was to investigate the effect of intermittent hypoxia training on women mountaineer’s hypoxic test performance. Materials and Methods: In order to do this, after calling female mountaineers in Kermanshah, 12 female mountaineers with average age of 29.00±8.00, height of 162.41±4.71 centimeters and weight of 54.15±7.27 kilogram, were included. After completing health questionnaires and a consent form, participants were randomly divided into control and experimental groups. Intermittent hypoxia training for 15 days, every day for an hour (5 min hypoxic air and 5 minutes normoxic air, through the hypoxicator set in the sitting position) was performed. Severity of hypoxia in the first 5 days was %11, in the second 5 days 10%, and the third 5 days 9% oxygen in expired. At the beginning and end of intermittent hypoxia training, hypoxic test sets consisting of two components that named TD and TR were taken from both groups. Results: The Wilcoxon test was used to assess changes in 0.05 showed that after 15 days, an increase of Td in the experimental group than the control group (147.29% vs. 4.93 percent), this difference was significant, also TR decreased in the experimental group than the control group (37.24% vs. 21.20%), but this difference was not significant. Conclusion: The results of study suggest a positive effect of intermittent hypoxic training on test on mountaineers’ hypoxic test performance in TD.
