The subject of muscular exercise should be of more than mere academic interest to the pediatrist. A clearer understanding of the physiology of this subject and the establishment and effective application of physiologic standards will lead to a higher degree of efficiency of our school children and will increase our knowledge of diagnosis in children from a functional point of view. Only on the basis of quantitative scientific investigation of the physical capacity of normal children of all ages and
