摘要：The aim of this study is to investigate the relationship between Somatotype with aerobic capacity and balance in males of 11-13 years. The random-volunteer sampling method was employed in this study to select 90 male students of 11 to 13 years of age. Height,weight,BMI,BF%,the thickness of subcutaneous fat in four areas of the body,the area of the body in two points,the width of the arm and thigh bones,and the aerobic capacity and balance were calculated and somatotypes were determined using Heath-Carter somatotype method. The data were then analyzed through SPSS 18 software,using Spearman correlation method. The results indicated a significant relationship between the aerobic capacity and the values of ectomorphy (r = -0.59),endomorphy (r = 0.69),and mesomorphy (r = 0.57). In other words,the greater the values of endomorphy and mesomorphy got,the greater the record of the 540-meter test got,which means the lesser the aerobic capacity got. However,the opposite was true regarding the value of ectomorphy. Inclination towards endomorph-mesomorph somatotypes is a factor that affects the cardiorespiratory system and balance. Thus,on the one hand,decreasing the amount of fat in individuals with obesity can improve their move and dynamism,and on the other,increasing the weight in thin individuals without increasing their body fat,or more accurately,increasing their muscle tissue can lead to their fitness,which in case results in an increased self-confidence and increased desire and inclination towards exercising and working out,leading to increased efficiency of their physiologic and metabolic systems..
