FIG. 1& PERCENTILES OF VITAL CAPACITY FOE GIRLS (SMEDLEY) 98 PHYSICAL AND MOTOR CAPACITY Schuster found the general correlation between vital capacityand height to be -f- .57, and that between the same capacityand weight to be -f- .59. It follows that in estimating thestatus of a given individuals vital capacity allowance must bemade for his size of body as well as for his age. (4) Dependence on age. The general dependence on age isindicated in the norms already given. It may be mentionedfurther that the most marked individual differences appear atthe ages when the period of most rapid growth terminates(Smedley). Concerning the further development of vital ca-pacity after the period of adolescence, Beyer, from his studyof naval cadets, concludes that maximal capacity is reached at19, but other authorities place the maximum at 35, with anannual decrease of about 32 cc. thereafter up to the age of 65. (5) Dependence on mode of life. It has been pointed outabove that vital capacity m
