The study aims to examine the impact of three months of resistance training, non-training, and retraining on the serum levels of IL-8 in middle-aged men.
In this study, 40 eligible middle-aged men (aged 30 to 50 years) were randomly selected. They were divided into two groups based on anthropometric indicators and maximum repetition of exercise movements: an intervention group (EXE) consisting of 20 individuals, and a control group (CTR) also consisting of 20 individuals. Both groups underwent a training period(12 weeks), a non-training period (12 weeks), and a retraining period (12 weeks) under the researcher's supervision. Kolmogorov-Smirnov and Lilliefors tests were used to assess data normality and variance homogeneity. The repeated measures analysis of variance test was employed to compare the groups on the studied variables, with a significance level set at P>0.05.
Based on the results obtained from the analysis of variance test with repeated measurements, 12 weeks of resistance training increases serum levels of IL-8 in middle-aged men. A non-training period (three months) causes these levels to return to their original state. Furthermore, 12 weeks of retraining increased these levels more than the initial training period.
IL-8 is involved in muscle adaptations caused by resistance training in the phenomenon of muscle memory. As a strategy for improving physiological conditions, increasing protein synthesis, and enhancing the strength, volume, and function of muscle mass in middle-aged individuals, it should be considered.

The overall aim of this study was to investigate the effect of eight weeks of upper quadrilateral training on chronic middle-age men's headache.

The research method was semi-experimental and research design was pre-test and post-test. The statistical population of the study included all middle-aged men with tension headache referring to health centers affiliated to Tehran University of Medical Sciences. The sample consisted of 6 subjects who were selected from among those referring to health centers. The criteria for entry into the study included: confirmation of the criteria for chronic tension headache by a neurologist and having a range of 40- 55 years. Information about the severity and frequency of headache and drug consumption in both groups before and after the exercise were assessed by a self-assessment questionnaire. Subjects' sleep quality was assessed in two stages: pre-test and post-test using the Pentecostal sleep quality questionnaire. Became

T-test results (at the level of error of α = 0.05) showed that eight weeks of upper quadrilateral training on the severity and duration of chronic tension headache and also the reduction in the dose of analgesics and ultimately the sleep quality of people with tension-type headache Chronic effects had a positive effect (p <0.001).

The results of the study suggest that occupational therapists use upper quadrant physical exercises to improve the patient's cold pain.

The purpose of the present study is to review the effect of 8 weeks of concurrent training on plasma concentration of Irisin and Brain-Derived Neurotrophic Factor (BDNF) in overweight middle-aged men.20 healthy middle-aged men with the average age of 51.3±7.5 were randomly chosen and divided into 2 groups of test (10 members) and control (10 members) groups. The participants in the test group took part in 8 weeks of concurrent exercise. The work out plan consisted of 10 minutes of warm-up, 25 minutes of aerobics, 30 minutes of endurance activities, and 5 minutes of cool-down. Blood samples were tested before the test and 48 hours after the last work out session in order to measure Irisin and BDNF levels by ELISA test. For data analysis, t-test was used. The results showed that plasma concentration of Irisin and BDNF levels increased significantly in the test group compared to the pre-test (P≥ 0.001). Also, the comparison between test group and control group in post-test indicated high plasma levels of Irisin and BDNF in the concurrent test group (P≥ 0.001). Furthermore, there was a significantly positive relation between plasma changes of Irisin and BDNF (r-0.569; P≥ 0.01).  It seems that concurrent exercising can positively regulate Irisin and BDNF levels in overweight middle-aged men and thus fight against the harmful effects of aging.

The aim of this study was to evaluate cardiovascular recovery after running on a treadmill with different intensities with N95 and surgery masks in middle-aged men.

72 healthy men were randomly divided into six groups: 1. Surgery + submaximal, 2. N95 + submaximal, 3. Surgery + maximal, 4. N95 + maximal, 5. Sub maximal without mask, 6. Maximal without mask. The sub-maximal and maximal exercise protocols included running at a speed of 1.34 m / s with 5% for 20 minutes on a treadmill and a modified Bruce test, respectively.

Hemodynamic factors were measured before, immediately, 1, 3 and 5 minutes after exercise. Analysis of variance in repeated measures was used to analyze the data. Changes in heart rate, systolic pressure, and myocardial oxygen consumption during the recovery period after exercise were not significant in groups with the same activity (maximal or submaximal) with or without masking conditions. Heart rate was significantly higher in N95MAX vs. SURMAX at 1 min after maximal exercise. HR, SBP, and DP were significantly lower immediately after anaerobic exercise within 1 and 2 min of the post recovery period.

Our results showed that facial masks with exercise in healthy individuals can be used during COVID-19 pandemic disease, without having negative effects on postoperative cardiac recovery performance.

Cardiac autonomic system dysfunction in type 2 diabetic patients can lead to diabetic neuropathy. The purpose of this study was to investigate the meta-analysis of the effect of aerobic exercise on cardiac autonomic system in middle-aged men with type 2 diabetes.

A total of 256 related articles were selected by searching in the Pubmed, Web of Science, ScienceDirect and Magiran databases. Finally, considering the inclusion criteria, 11 articles were selected for evaluation and analysis after validation using PEDro scale. PICOS method was used to extract data from each article. Then, they were analyzed using Comprehensive Meta Analysis V3.exe software with group comparisons method and random and fixed effects size models of each study.

Regular participation in aerobic training programs in middle-aged men with type 2 diabetes had significant effects on SDNN as time domain index (p = 0.004; effect size = 0.33) and HF as frequency domain index (P = 0.017; effect size = 0.23). Also, these exercises had an insignificant effect on the rMSSD as time domain index (p = 0.096; effect size = 0.50) and LF as frequency domain index (p = 0.184; effect size = 0.47).

Regular participation in moderate intensity aerobic exercise in middle-aged men with type 2 diabetes can partially prevent the effects of this disease on cardiac autonomic system function. Therefore, it is recommended for middle-aged diabetic patients to consider exercise as one of their therapeutic modalities.

Lipocalin-2 is a novel adipokine which is secreted from adipose tissues and is closely associated with low inflammation, obesity, insulin resistance and metabolic syndrome. The aim of this study was to investigate the effect of 8 weeks of selected aquatic aerobic training on lipocalin-2, glycemic indices and lipid profile in overweight middle-aged men. 24 overweight men (BMI≥25 Kg/m2, age range of 45 to 55 years old) were selected randomly from 70 volunteers after a public call. After they met necessary requirements, they were divided into experimental (n=12) and control (n=12) groups. Training program included selected aquatic aerobic training with 45-65% of maximum heart rate for 8 weeks. Blood samples were collected before and after training to measure study variables. The comparison of control and experimental groups with independent t test showed a significant difference in lipoprotein-2, insulin resistance index, cholesterol, triglyceride and LDL-C (P<0.05) while changes in glucose, insulin and HDL-C variables were not significant (P>0.05). Results showed that aquatic aerobic training could have positive effects on reducing some cardiovascular risk factors in overweight middle-aged men. Therefore, these types of training can be recommended by sport and health experts for these individuals.

This study was designed to compare morning and evening exercises on a change in levels of salivary immunoglobulin A (IgA), cortisol, and total protein in middle-aged men. For this purpose, 12 middle-aged men (age: 53.42±6.87 years; BMI: 25.21±2.88 kg/m2) participated in this study. They had an endurance training session for 45 minutes with 65% of maximum heart rate in the morning (7 - 8 am) and evening (5 - 6 pm) with a 2-day interval. Salivary immunoglobulin A, cortisol, and total protein levels were measured in the morning and evening (before and after the exercise) by ELISA method. Data were analyzed using analysis of variance with repeated measures and Bonferroni post hoc test. The results showed that morning exercise significantly decreased salivary cortisol concentration levels (P=0.03). No significant changes were observed in other measures. In conclusion, morning exercises reduces salivary cortisol levels in middle-aged men.

Vaspin as a new adipocytokine improves insulin sensitivity. Despite the effects of exercise training on energy homeostasis and changes in fat tissue, few studies have investigated the effect of exercise training on vaspin. This study investigated the effect of resistance training on serum levels of vaspin and CRP. 20 sedentary obese men (mean SD age: 50.1 2.1 years, weight: 92.6 5.8 kg, BMI: 30.3 1.4 kg/m2) were selected and randomly divided into two groups: exercise (n=10) and control (n=10). Training program of the experimental group consisted of 3 sessions a week for 12 weeks. Blood samples were gathered after 12 hours of fasting and then 48 hours after the last training session in the experimental condition. Serum levels of vaspin and CRP decreased (8.8%, 2.5% respectively) in the experimental group after 12 weeks (P˂0.05). Weight, BMI, BF% and waist circumference significantly decreased (-0.7%, -0.8%, -2.08% and -1.01% respectively). Blood glucose and insulin resistance significantly decreased (respectively 4.4%, 5.01%) (P˂0.05). There was no significant relationship between changes of vaspin and anthropometric indexes, insulin resistance and CRP.

Introduction and

Brain natriuretic peptide (BNP) is principally synthesized and released by ventricular myocytes in response to myocardial wall stress. Acute and chronic effects of resistance and endurance exercise on N- terminal pro brain natriuretic peptide (NT pro BNP) are still unclear.

The aim of this study was to investigate the acute and chronic effects of resistance versus endurance training on NT pro BNP level in middle-aged men.

Twelve middle-aged men were randomly assigned to resistance or endurance group. Resistance training consisted of 8 weeks weight training، 3 days a week، at an intensity corresponding to 50% of one-repetition maximum. The endurance training programme included continuous running at an intensity corresponding to 70% of maximal heart rate، 3 days a week for 8 weeks.

The results demonstrated that NT pro BNP increased (P<0. 05) after a session of endurance training، however it decreased (P<0. 05) after 8 weeks endurance training. Besides، NT pro BNP has not significant change after a session of resistance training، while it increased (P<0. 05) after 8 weeks resistance training.

In summary it seems that the acute and chronic effects of resistance exercise differ with the effects of endurance exercise. Endurance training improved myocardial function compare to the resistance training; however further studies are needed.
