Background:Studies show that lack of exercise and physical activity during childhood and teenage years is directly related to different diseases in adulthood.Objectives:The main purpose of this study was to investigate the effects of an eight-week aerobic exercise on the quality of life as well as physiological indicators of cardiovascular endurance of inactive high school male students in Kashan.Materials and Methods:The study was a field trial using pretest and post-test. Three hundred high school male students in Kashan, Iran, were recruited and interviewed by the researchers, using a questionnaire. Of the inactive ones, 30 who reached the highest criteria standards, were selected as samples and randomly divided to two equal groups. The maximum consumed oxygen (VO2max) and resting heart rate were measured by Quinn aerobic test, and the quality of life was measured by the World Health Organization Quality of Life (WHOQOL-26-Breef) questionnaire. The exercise program included an eight-week aerobic exercise, three times per week, with 60%-75% of the maximum heart beat. During the exercise, the subjects had no other sport activity. To check the normal distribution of the data, Kolmogorov-Smirnov test was used. To evaluate the pretest and post-test results, paired t-test was used and for comparing the groups, independent t-test was applied. All the analyses were performed by SPSS software version 16.Results:The mean ages of intervention and control groups were 17.46 ± 1.30 and 17.53 ± 1.18, respectively. The mean weight of the intervention group was 56.73 ± 9.91 kg and its mean body mass index (BMI) was 19.88 ± 3.42. In the control group, the mean weigh and BMI were 60.06 ± 11.96 kg and 20.79 ± 3.51, respectively. The quality of life and its components improved significantly in the intervention group (physical (P = 0.0001), mental (P = 0.0001), social (P = 0.0001), and environmental (P = 0.0001) aspects). VO2max (P = 0.001) and the resting heart beat (P = 0.0001) significantly improved in the intervention group. No significant difference was observed in the control group (P ≥ 0.05).Conclusions:Aerobic exercise program improved the quality of life as well as the physiological indicators. Physical activities can be used as both appropriate model and nonpharmaceutical approach to prevent and cure some diseases.

Objective: The production of reactive oxygen species in exercise causes oxidative stress which disturbs the balance of oxidants and antioxidants, causing destructive effects on cells. The present study aims to investigate the effect of three types of massage (Swedish, Russian, Thai) on serum levels of Malondialdehyde (MDA), Glutathione Peroxidase (GPX) and Superoxide Dismutase (SOD) following one session of exhaustive exercise. Methods: This quasi-experimental study was conducted on 48 female futsal players aged 17-22 years in Zahedan, Iran who were selected using a purposive sampling method, and randomly divided into four groups of Swedish massage (Long strokes with pressing and tapping using hands), Russian massage (Medium to high pressure), Thai massage (Pressure to certain parts of the body) and Control. The exercise program was based on Bruce protocol. Serum levels of MDA, GPX and SOD were measured by before and immediately after exercise and after massage. Data analysis was performed using repeated measures ANOVA, considering a significance level of P≤0.05. Results: In all three types of massage, there was a significant decrease in serum level of MDA (0.22±0.08), and a significant increase in GPX (1.84±0.46) and SOD (10.02±2.86) levels after exhaustive (P=0.001). No significant difference was observed in the control group. Conclusion: It seems that Russian, Thai, and Swedish types of massage can affect the serum levels of the MDA (as an oxidative stress marker) and the antioxidant enzymes of GPX and SOD during the post-exercise recovery period.

Background and Aims Diabetes pathogenesis is driven by a complex network of pro-inflammatory cells and cytokines, of which interleukin-6 (IL-6) plays a key role in the chronic inflammation associated with type 2 diabetes. The use of supplements and plant extracts and exercise to treat type 2 diabetes is common today. The aim of this study was to evaluate the simultaneous effect of aerobic training and resveratrol supplementation on IL-6serum levels in women with type 2 diabetes. Methods This study was a quasi-experimental study with a pre-test-post-test design and a control group, in which 24 women with type 2 diabetes were randomly assigned to three equal groups of supplement (age 55.25±5.11 years), training+supplement (400 mg resveratrol) (age 54.62±7.22 years), and control (age 52.25±8.60 years). The subjects practiced for six weeks and every week for three days for 40-60 min and at a heart rate of 45-65. Data analysis was performed using analysis of covariance and correlated t-test at the significant level of <0.05. Results The results showed that after the intervention, IL-6 serum levels in the aerobic training + supplement group (P=0.01) had a significant decrease compared to the supplement and control groups. Examination of intergroup changes shows that there was a significant difference in IL-6 levels between the training + supplement group and the supplement group (P=0.002, f=1.56). Also, the results of the Tukey post hoc test showed that there was a significant difference between the control group and the training + supplement group (P=0.003) and between the supplement group and the training+supplement group in IL-6 levels (P=0.031). Conclusion Based on the findings of the present study, it seems that concomitant use of resveratrol supplementation and aerobic training can reduce the levels of IL-6 and the supplement have anti-inflammatory and protective effects in women with type 2 diabetes.

Introduction: Total-Body Resistance Training (TRX) is a new method for increasing muscle strength and decreasing muscle atrophy and improving balance in the elderly. The purpose of this study was to investigate the effect of 12 weeks of TRX training on static and dynamic balance in older men. Methods: In this quasi-experimental study, 16 older men, with the age range of (62.06 ± 1.53 years), were selected as sample by availability sampling method; and were randomly placed in two TRX and control groups; each group n = 8. The experimental group practiced in a TRX exercise program for 12 weeks, each week, three sessions with a duration of 60 minutes. The collected data were analyzed by paired t-test and analysis of covariance (ANCOVA) at a significant level of P < 0.05. Results: The results of paired t-test showed that there is significant difference between pre-test and post-test for static (t =-22.40, P = 0.0001) and dynamic (t = 13.8, P = 0.0001) balance in TRX group. Also the results of ANCOVA test showed that there was significant difference between TRX and control groups in static (F = 495.45, P = 0.0001) and dynamic balance (F = 74.94, P = 0.0001). Conclusions: It seems that TRX exercises can increase static balance time and decrease dynamic balance time in older men. Probably by using this exercise method, negative physical consequences, and consequently, treatment costs can be reduced. This method can be useful in the field of elderly nursing.
