The purpose of this study was to clarify whether changes in BMI were associated with physical fitness improvements in youth after a one-year period. The subjects were 287 youth male students aged between 15 and 18. A physical fitness test was conducted using the new physical fitness test with 8 items for youth aged between 12 and 19 years, developed by the Ministry of Education, Culture, Sports, Science and Technology of Japan to assess their physical fitness level at baseline and after a one-year period. The subjects were divided into 6 groups (LD, LI, ND, NI, HD, HI) by a combination of the baseline BMI value (low, normal, high) and the BMI change after the one year period (decreased, increased). These results of the present study demonstrated that physical fitness improvements were different in each subject group. There was no significant physical fitness improvement in the LD and HI groups, whereas the other groups showed significant improvements in their physical fitness level (P<0.01). The results suggest that adequate improvements in physical fitness occurred during youth period. However, their improvements in physical fitness may be hampered by progression of underweight and overweight status, respectively. - Body mass, nonspecific low back pain, and anatomical changes in the lumbar spine in judo athletes.

The purpose of this study was to investigate relationships between low back pain (LBP) and psychological conditions in university wrestlers. We examined psychological conditions of seventy male university wrestlers using the Psychological Condition Inventory (PCI) test and evaluated whether psychological conditions have some relationships with LBP. Evaluations of LBP were based on a questionnaire test and the diagnosis of orthopedic surgeons. Based on the LBP evaluation, we assigned all wrestlers into two groups as the LBP group and the non-LBP group. We obtained the following results. There were twenty-eight university wrestlers (40%) in the LBP group and forty-two wrestlers (60%) in the non-LBP group. Wrestlers in the LBP group showed significantly high values in all factors relating to fatigue in comparison to the non-LBP group. We conclud that the university wrestlers with LBP feel fatigue in their minds and bodies.
