  • Comparison of performance indicators between different football positions
           using the global positioning system (GPS)

    • Abstract: The purpose of this study is to compare the performance indicators between different football positions using the Global Positioning System (GPS) in Iranian Premier League football players.This is quasi-experimental study. To conduct this research, 18 football players who are members of a club in the Iranian Premier League were selected as the available sample, and the players were divided into 6 groups based on the game post. Then the data related to the players' performance (total distance, distance traveled with maximum speed, duration of maximum speed, maximum speed, sprints, number of accelerations, and number of decelerations) in 6 consecutive matches Collected using Global Positioning System (GPS). Also, one-way ANOVA analysis and SPSS software were used for data analysis at a significant level (α = 0.05).Based on the findings of the present study, between different football positions for the variables of total distance (P≤0.00), distance traveled at maximum speed (P≤0.00), duration of maximum speed (P≤0.00), maximum speed (P≤0.00), sprints (P≤0.00), number of accelerations (P≤0.00) and number of decelerations (P≤0.00) there are significant differences.There are many fundamental differences between the performance indicators of different football positions with each other it is necessary to recognize these differences and it is necessary to consider special exercises according to the physiological needs of each post.
  • Examining the functional motor screening (FMS) scores of Mobarake Sepahan
           handball players

    • Abstract: 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
  • Effect of 8 weeks of Endurance Training on Volume and Capacity of Lungs
           (FEV1/FVC, FEV1, FVC) and Its Relationship with BMI in Male Smoking

    • Abstract: The aim of this study was to investigate the effect of 8-weeks endurance training on volume and capacity of lungs (FEV1/FVC, FEV1, FVC) and its relationship with BMI in Male Smoking students. 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. 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 ). Finally, 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.
  • The effect of a pulmonary rehabilitation exercise program on patients
           after COVID-19: A report of three cases

    • Abstract: Objectives: 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.Findings: 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.
  • Acute Response of Muscular Damage Biomarkers after HIFT Exercise in
           Overweight Men

    • Abstract: 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.
