ABSTRACT

Seven long distance runner aged from 51 to 75 were tested on the view point of physical fitness and results as follows.<BR>1) Mean values of maximum VO<SUB>2</SUB>ml/kg/min, maximum heart rate and maximum respiratory rate during all out running were 43.7, 170 and 56.4 respectively.<BR>2) The maximum heart rate, maximum respiratory rate and oxygen intake during 5 minutes walking with the speed of 120 meter/min. were 80 percent, 64 percent and 77 percent of the former respectively.<BR>3) A case that was able to run one hour under the condition the heart rate continued about 200 beats was found.<BR>4) The systolic blood pressures were rised during walking and running but were decreased below the level of starting time in 5 to 10 min. after the stop of them.<BR>5) It was presumed that the speed of initial stage of long distance running should be held relatively slow for the aged to perform their ability reasonavely.<BR>6) The girth of lower leg became large by the long distance running on the case of man, but not on the case of woman.<BR>7) The skinf old of them were reduced of all.<BR>8) Vital capacity ratio one second/max and side step test were high level, but the grip strength, vertical jump, backward flexibility, forward flexibility and static endurance of leg were not always high compared with ordinary level of same aged.<BR>9) The size of heart shade of them were almost appeared in the normal range.<BR>10) Anemia caused by hard training was found in all cases.
