The purpose of current study was to determine if there was correlation between body mass Index (BMI) with muscle strength and muscle fatigue in normal children with different body weight. Seventy five Subjects of both sexes with ages ranged from 10 to 13 years old were chosen from awlady association in maadi. They were classified into three groups according to their BMI Group A (normal BMI < 85th percentile), Group B (overweight < 85th to >95th percentile) and Group C (obese < 95th percentile). All children had been assessed by biodex Isokinetic dynamometer at 60{u00B0} / sec angular velocity for peak torque and time to fatigue of quadriceps and Triceps muscles, and abdominal muscles were assessed by manual muscle testing (MMT). The results revealed statistically positive correlation between BMI and muscle strength in quadriceps and triceps muscles while negative correlation between abdominal muscle strength and BMI and negative correlation with muscle fatigue. There was correlation between muscle strength and muscle fatigue with body mass Index as peak torque increase as BMI increases in quadriceps and triceps muscles but in abdominal showed inverse relation between muscle strength and BMI and time to fatigue decrease as BMI increases
