The declining trend in the physical fitness of young people poses a severe problem. This trend in physical fitness is considered one of the important factor occurring due to the difference in morphological quality judged by body composition. However, few studies of the kind reported. In the present study, the physical fitness based on difference of morphological quality is confirmed in high school boys. The sample size consists of 146 high school boys aged 16 years. Height, weight, body mass index (BMI), body fat mass, percentage of body fat, soft lean mass (SLM), bone mass and bone mineral density for physique and body composition were measured, in addition to, grip strength, sit-up, sit & reach, side step, 20m shuttle run, 50-m dash, standing long jump and hand ball throwing were measured as physical fitness tests. 20m shuttle run, sit-up and hand ball throwing showed a significant difference among "slim type," "normal type" and "fatty type", classified by the fatty-slim degree judgment based on BMI. Next, a regression polynomial evaluation chart of fat percentage for BMI was constructed in order to examine the physical fitness based on the difference of morphological quality. Physical fitness was examined based on the difference in the degree of qualitative accumulation of fat (excessive development of fat, normal fat, excessive underdevelopment of fat) derived from the evaluation chart. As a result, the student with excessive development of fat was significantly inferior and the excessive underdevelopment of fat type student was significantly superior in grip strength, standing long jump and hand ball throwing ability of the excessive development type. The result indicated a difference in physical fitness based on the difference in the degree of qualitative accumulation. This suggests that the fat percentage was a negative factor for motor ability.

In the present study, the relational construction between body composition and physical fitness is confirmed regarding physical fitness based on polynomial regression evaluation of body fat percentage for body mass index (BMI) in adolescence. The sample size consists of 384 Korean junior high school students aged 13 years (boys: 200; girls: 184). Height, weight, BMI, body fat mass, body fat percentage, soft lean mass were measured along with physical fitness tests (sit & reach, 20 m-shuttle run, push up and sit up). Physical fitness showed a significant difference among "slim type", "normal type" and "fatty type" classified by the fatty-slim degree judgment of BMI. Next, a polynomial regression evaluation chart of fat percentage for BMI was constructed in order to verify physical fitness by the difference of body form quality. Physical fitness was examined based on difference in the degree of qualitative accumulation of fat (excessive fat, normal fat underestimated fat) derived from the evaluation chart. As a result, the excessive fat person was significantly inferior and the underestimated obese person was significantly superior in endurance ability in the normal type. There was a difference in physical fitness based on the difference in the degree of qualitative accumulation of fat. This suggests that the fat was a negative factor for endurance ability in normal type based on the fatty-slim degree judgment of BMI.
