Physical fitness of 1886 M.S.D.F. Crewmen were measured, and the following results were observed.1) In 1500 meter-run and 5O meter-dash of sandbag carry, there was a declining tendency according to the age increase from eighteen years old. The l00 meter-dash, softball throw, pull-up, and long jump showed the highest records in the period from twenty years old to twenty-five years, old. No change was found in back-strength and grip-strength in the period from twenty years old to thirty-four years old. 2) Motor ability of crewmen was negatively related to the length of service. However, this, tendency was vanished except 1500 meter-run, when the effect of age-increase upon motor ability was considered. It was presumed that two-third of the declining tendency of 1500 meter-run was caused by the age and one-third by the length of service. It will be a theme in the future to design some training methods for maintenance and elevation of the endurance.
