Student of Exercise Physiology, University of Tehran Journal Article 2019 03 02 Understanding health-related fitness status, especially body composition and cardio-respiratory fitness indicators is an important factor in determining individual health. The purpose of this study was to developing and updating the physical fitness norm for men aged 18-60 years old of Tehran province. In this descriptive cross-sectional study, 250 men aged 18-60 years old with a mean age of 31.28 ± 9.39 years, height 176.65 ± 6.64 cm, weight 83.00 ± 13.30 kg from different regions of Tehran were recruited by cluster and random sampling and divided into different age classes. In this study, body mass index (BMI), waist to hip ratio (WHR), body fat percentage (caliper), cardio-respiratory fitness (Rockport 1mile walking/Running), Flexibility (sit & Reach), endurance of abdominal muscles (curl up), Endurance of shoulder girdle muscles (modified push up) and strength of hands (hand grip) measured in subjects. Descriptive statistics, z equation and percentage points were used to prepare the relevant norms. The findings of this study showed that the mean cardio respiratory fitness (45.78 ± 10.42 ml / kg.min-1), body fat percentage (27.45 ± 7.41), BMI (26.54 ± 3.63 kg) Flexibility (27.43 ± 10.49 cm), endurance of abdominal muscles (33.36 ± 11.62), WHR (0.86 ± 0.57), Endurance of shoulder girdle muscles (24.71 ± 15.15), strength of hand muscles (45.18 ± 7.79 kg). The results of this study can be used as a reference for health and clinical studies in different age groups.
