Purpose: The aim of this study was to investigate the acute effects of HIFT exercise, on creatine kinase (CK) and lactate dehydrogenase (LDH) in blood serum in overweight adult men. Method: Twenty-two untrained non-smoker overweight men (age, 42.9 ± 5.6 years; body mass, 94.2 ± 9.3 kg; body height, 178.9 ± 4.5 cm; and BMI, 29.04 ± 3.3 kg/m2) volunteered to participate in this study and performed a session of HIFT exercise with 80-85% HRmax consisting of three sets of 10 exercises. Blood samples were collected before and immediately after training to measure serum CK and LDH levels. Results: The HIFT protocol significantly increased serum CK (Pre: 114.6 U/L; Post: 124.3U/L; p< 0.05{t=-5.48, p=0.001}); Also, LDH had a significant increase (pre:213.4 U/L, post: 225.4U/L; p<0.05{t=-4.09, p=0.001}). Conclusion: It can be concluded that HIFT with AMRAP (as many repeats as possible) protocol will lead to a significant increase in some indicators of muscle damage such as CK and LDH levels in overweight men. This protocol can lead to muscle damage in overweight men.

Purpose: This study aimed to investigate the effect of a pulmonary rehabilitation exercise program on post-COVID-19 patients. Method: Three patients (two women and one man) with different severities, from moderate to severe, were selected. Blood pressure, heart rate, blood oxygen, and body function were measured at the beginning and end of the exercises, which included 12 sessions of arm and leg cycle ergometer and treadmill with adjustable resistance levels. Patients’ functionality was assessed using the Barthel index, and their quality of life was assessed using the SF-36 questionnaire. Results: Regarding the first patient, oxygen saturation increased from 85 to 95, the 6-minute walk test (6MWT) result increased from 0 to 420 meters, and the Barthel index increased from 35 to 85. For the second patient, arterial oxygen saturation increased from 82 to 92, the 6-minute walk test (6MWT) result increased from 0 to 390 meters, and the Barthel index increased from 30 to 90. For the third patient, arterial oxygen saturation increased from 87 to 96, the 6-minute walk test (6MWT) result increased from 320 to 510 meters, and the Barthel index increased from 60 to 85. All the patients showed improvements in their physical functions, such as walking, personal affairs, and quality of life. This functional improvement was higher in more severe levels of the disease. Conclusion: Based on the results, it seems that pulmonary rehabilitation exercises for post-COVID-19 patients can contribute to the improvement of their status, arterial oxygen level, quality of life, and pulmonary functionality.

Purpose: The aim of this study was to investigate the effect of 8-weeks endurance training on volume and capacity of lungs (forced expiratory volume in 1second, Forced vital capacity, ratio FEV1/FVC) and its relationship with BMI in Male Smoking students. Method: In order to accomplish this research 20 cigarette addicted men students referred to the smoking cessation clinic were randomly selected and were divided into two groups of experimental (n=10) (age: 15.33 ± 2.07 years and BMI: 25.41 ± 3.55 kg/m2) and the control group (n = 10) (age: 15.10 ± 2.81 years and BMI: 27.26 ± 66 kg/m2). The Spirometry indexes (FEV1/FVC, FEV1, FVC), height and weight were measured Prior and after 8-weeks of endurance training. Experimental group performed 8-weeks of progressive endurance training (3 sessions per week, 60 minutes per session) which included running with the intensity of 75% MHR. Intensity of exercise was controlled by maximum heart rate and the formula of (220-age) and the intensity level and duration of exercises increased in each session. Data analysis was done by using the variance analysis method for repetitive data and the independent T-test. Results: The results of this study showed that after eight weeks of endurance training, Spirometry indexes (FEV1/FVC, FEV1, FVC) significantly increased (P<0.05), and this increase had a negative relation with BMI (P<0.05, r=-0.62). Conclusion: the study showed that eight weeks of moderate-intensity endurance training improved volume and lung capacity of Male Smoking students and it could partly remove the damaging effects of smoking on physical and psychological health and it can help them quit smoking as well.

Purpose: Functional Movement Screening Test (FMS) is a tool that has the ability to determine a person's potential for the possibility of suffering from musculoskeletal abnormalities and sports injuries. FMS tests include seven functional movement tests that evaluate trunk, central strength and stability, neuromuscular coordination, asymmetry in movement, and flexibility. The purpose of this research was to determine the norm of the functional motor screening test in the male handball players of the Sepahan club in Isfahan.Method: The method of collecting information is cross-sectional and in terms of practical purpose. For this purpose, 30 male students aged 14-16 from Sepahan Handball Club of Isfahan were evaluated by performing 7 FMS tests.Findings: The norm of FMS test in 14-year-old students was 14.39±1.66, in 15-year-old students it was 15.85±1.47, and in 16-year-old students it was 15.29±1.21. Therefore, it can be stated that the FMS scores in these people are in a better condition compared to related studies in this age group. Also, the test scores separately showed that 75% of this population does not have enough stability in the central part of the body.Discussion and conclusion: In many sports activities, the movements of the upper and lower limbs need to have sufficient stability in the central area, if there is no stability in this area, energy transfer does not take place well. Since this age group is at the beginning of official sports competitions and considering that the clinical usefulness of FMS is limited by the lack of Norm index in Iran, sports medicine specialists and sports team coaches can evaluate the value of Norm scores to diagnose and identify people. at the risk of physical deformity and injury at different ages and plan bodybuilding and corrective exercises based on it

Purpose: The world is getting old. Alzheimer's disease is a progressive disease, which in case of no intervention, this ratio reaches 4 more advanced stages in people over 85 years old. Some methods have shown that they can be effective in preventing and slowing down the course of the disease. The purpose of this study was to investigate the role of aerobic exercise program on the quality and Lipid profile related to sleep in the elderly with Alzheimer's disease. Method: 22 elderly people with Alzheimer's disease were randomly divided into two groups of 11 people: aerobic exercise and control. The subjects in the aerobic training group practiced three sessions every week for twelve weeks and each session lasted for 45 minutes. The sleep quality of the subjects was evaluated by the Pittsburgh Sleep Quality Questionnaire (PSQI). Lipid profile related to sleep (TG, TC, LDL, HDL) was also measured by blood sampling before and after twelve weeks of aerobic training. Results: The results showed that the sleep quality of the subjects improved by 31% in the Pied Heroi group, which was statistically significant. In addition, there was a significant improvement in the changes of TG (p=0.034), TC (p=0.017), LDL (p=0.006), and HDL (p=0.016) in the aerobic training group. The results of the independent t test also showed that there was a significant difference in sleep quality between the aerobic exercise and control groups. However, no relationship was observed between changes in sleep quality and changes in Lipid variables related to sleep. Conclusion: It can be concluded that twelve weeks of aerobic exercise improves sleep quality along with Lipid profile related to sleep in the elderly with Alzheimer's disease and will be useful as a way to treat sleep problems in the elderly.

Background: Limited research has investigated the use of chamomile as an antioxidant supplement in team sports. Purpose: The aim of this study was to investigate the effect of chamomile extract on antioxidant indices in young female futsal players. Methods: 20 young female futsal players (Average age: 22.08 ± 5.03 years, weight: 54.4 ± 8.62 kg, and body mass index: 20.56 ± 2.6 kg/m2) were divided randomly into two groups, experimental group (10 people) and control group (10 people). The experimental group consumed 1500 mg/day of the supplement for one week, while the control group received a placebo. Both groups were nutritionally controlled during this period. After the end of the intervention period, two simultaneous futsal matches were held for two groups (two teams of 5 players in each match). Anthropometric characteristics were evaluated in resting conditions and biochemical markers were measured before the intervention, immediately after the competition, and 30 minutes after the competition. Data analysis was performed using the repeated measurement variance test. The level of significance was considered at P<0.05. Results: The results showed a significant increase in SOD levels (P<0.05) and a significant decrease in CAT levels (P<0.05) immediately after the competition in the supplement group, but this significance was not seen 30 minutes after the competition. Conclusion: One-week consumption of chamomile improves antioxidant defense in young female futsal players. Conducting studies with long-term follow-up to confirm these findings should be considered.

Purpose: Sleep quality decreases with age, and as a result, sleep complaints are common in the elderly, especially for inactive people with Alzheimer's disease. Therefore, the aim of this study was to investigate the relationship between respiratory indices and sleep quality in active and inactive elderly women with Alzheimer's disease. Method: In this research, 24 elderly women with Alzheimer's disease (with an average age of 72.3±7.25 years, height 158.23±6.12 cm and weight 70.23±8.12 kg) voluntarily and after obtaining consent, they participated in two active (12 people) and inactive (12 people) groups. Respiratory indices were measured using a Micro Lab Spirometer. The Pittsburgh questionnaire was used to check sleep quality. Independent t-tests and Pearson's correlation coefficient were used to analyze the data. Results: The average score of sleep quality in the active group was significantly lower than the inactive group (p=0.013). Also, the parameters of expiratory volume with pressure in the first second (p=0.046), maximum voluntary ventilation (p=0.021), forced vital capacity (p=0.033), strong expiratory flow 25 to 75% in the active group was significantly higher than the inactive group. Conclusions: According to the results, it seems that sports activity can be an effective factor in improving the quality of sleep and the functioning of the respiratory system in patients with inactive Alzheimer's disease.
