This study was aimed at investigating the correlation between a person’s physical strength and the thickness of his/her upper body parts. So, we conducted fitness tests and measured the muscle and fat thickness of upper body, targeting 117 women (Group of 47-64, Group of 65-87). Measurement items were their arm power, sit-up exercise and the muscle and fat thickness(of anterior part of upper arm, posterior part of upper arm, anterior part of lower arm, abdominal part). As a result, the group of 47-64 was generally superior to the group of 65-87 in the fitness test. In the latter group, the associated items with the anterior part of upper arm(muscle thickness) were the extension movement, the flexion movement and the strength of grasp. In that group, the strength of grasp showed significant difference in the posterior part of upper arm(muscle thickness), the anterior part of upper arm(fat thickness), the anterior part of lower arm(fat thickness), the abdominal part(fat thickness) and the back part(fat thickness). But, in the former group, the fitness test items did not mostly show correlation with the anterior and posterior part of upper arm(muscle thickness), the abdominal part(muscle thickness) and the back part(muscle thickness). In conclusion, we think that several specific factors affect the muscle thickness of upper arm in older ages but that various factors complexly affect the muscle thickness of upper arm in younger ages. We think that more detailed studies will be needed in the future.
