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
