STUDY ON THE DEGREE OF BODYFAT TO BE RELATED WITH SOME PHYSICALFITNESS INDICIES IN MIDDLE AGED MEN AND WOMEN

Abstract

Healthy 51 men and 67 women aged from 35 to 49 years old were attended in this tests.
We measured their height, weight, skinfold, grip strength and blood pressure. Their performance concerning with running distance in 5 minutes, backward flexibility, forward flexibility, vertical jump, side step, Zig-Zag drible were tested too. The results were as follows.
1) In men the skinfold was rather thin, than that of estimated from relation of height-weight, on the contrary in women it was rather thick.
2) The running distance in 5 minutes of who have thinner skinf old was larger than that of who have thicker skinfold. It was also decreased with aged.
3) The backward flexibility was excelled in the group have thicker skinfold.
4) Excellent tendency of forward flexibility was shown in the case of thicker skinfold group.
5) High level vertical jump was observed over them and it was more high in thinner skinf old group than another.
6) Rather lower level of side step test records were obtained in all, especially in men that was remarkable.
7) Better records of Zig-Zag drible tended to be observed in the group have thicker skinfold.
From the above mentioned facts. I presume that the body fat might have more physical usefulness than we knew up to the present and as one of these usefulness it might be effective to privent the maturity of skeletalmuscle or to hold immature state of it. Finaly, I would like to claim we should have the body fat 12% of body weight in man, and 25% in woman, as the lower limit.
