High ranking Japanese weightlifters in Tokyo Olympics and high ranking adults and high school students in the 20th Japan National Athletic Meeting were chosen for the subjects. We made research about them for many patterns of movements of the Olympic three lifts which seemed to be the most reasonable way in analyzing the movements of the lifters, by comparing the results which were gotten by the 16 mm 64 frames side filming method with their official records and lifting marks. This led to the following conclusion :
1) At the begining of the clean, dead-lift, for the press the excellent lifters accelerate the bar at a higher speed, but the increase of speed after the begining is not so much. The Olympic lifters pull up the bar bending more forward, at a knee level. But excessive forword bending makes many lifters fail to clean weell.
2) Exellent lifters bigin pressing at a high speed by vigorous extension of their body, Less-trained lifters can not use vigorous extension of their body because of presing forward, or comming down the bar again, and bending the kenee joints.
3) In the snatch excellent lifters pull up the bar at a higber speed to the knees, but they at a speed of lower acceleration from the knees. Even if they are excellent lifters, they often fail to snach in the case of pulling with over-acceleration at that point. It is inportant also in the snatch to use effectively the power of lower ports of the body.
4) It is evident from the loci of the bar that, if the bar travells upward vertically, or near vertically, squat-style lifters need to jump back properly In the case they do not jump back the for moves back and forth excessively, many lifters fail to snatch if they jump back too much.
5) In the clean for the jerk an increasing acceleration in dead lift phase during clean is necessary to become a successful lifter. It is necessary to concentrate the power of the lower parts of the body as much as possible to accelerate on the bar to a knee level. From the knee level exce lent lifters pull the bar by using the pulling power of shoulders more aectively. The barbell falling down from the dead point must be held moderately not to fall down at a high speed.
6) If lifters overstrain the shoulder muscle groups and arms at the starting of the jerk and can not dip their body well in accordance weith dropp ing movement of the bar, they will fail to jerk.
7) The dropping speed of the bar at the first step of the jerk must be marked more carefully at the second phase than at the first phase. Many who make it increase more at the second phase will fail to jerk.
8) The bar of the excellent jerker goes up with very high speed at the begining. But of the speed of the bar after that there is no diffrence between lifters.

PURPOSE: The aim of this study was to evaluate the validity and reliability of the Seattle Angina Questionnaire, Japanese version (SAQ-J) as a disease-specific health outcome scale in patients with coronary artery disease. METHODS: Patients with coronary artery disease were recruited from a university hospital in Tokyo. The patients completed self-administered questionnaires, and medical information was obtained from the subjects' medical records. Face validity, concurrent validity evaluated using Short Form 36 (SF-36), known group differences, internal consistency, and test-retest reliability were statistically analyzed. RESULTS: A total of 354 patients gave informed consent, and 331 of them responded (93.5%). The concurrent validity was mostly supported by the pattern of association between SAQ-J and SF-36. The patients without chest symptoms showed significantly higher SAQ-J scores than did the patients with chest symptoms in 4 domains. Cronbach's alpha ranged from .51 to .96, meaning that internal consistency was confirmed to a certain extent. The intraclass correlation coefficient of most domains was higher than the recommended value of 0.70. The weighted kappa ranged from .24 to .57, and it was greater than .4 for 14 of the 19 items. CONCLUSIONS: The SAQ-J could be a valid and reliable disease-specific scale in some part for measuring health outcomes in patients with coronary artery disease, and requires cautious use.

　　In recent years, favorable therapeutic outcomes have been reported for arterial injection chemoradiotherapy for tongue cancer. The present case involves an 80-year-old woman in our palliative care department who had high-grade, advanced tongue cancer. Because there was a request for surgery to prevent airway occlusion due to growth of the tumor, she was referred to our department in April 2009. As a treatment policy for controlling tumor growth in high-grade, advanced tongue cancer, arterial injection chemoradiotherapy was carried out through the superficial temporal artery, with a tongue artery catheter in place on both sides. Therapeutic effect was obtained, and it was possible to avoid airway occlusion through tumor regression. Dysphagia and dysphemia were improved, which in turn improved quality of life. In this case, there was an opportunity to carry out multidisciplinary team medicine, including support from the oral care and palliative care teams as part of the process of cancer therapy. Here, we present our findings in this case.

We investigated the efficacy of choreitogoshimotsuto for radiation hemorrhagic cystitis. Of the 11 patients who could be followed up, hematuria disappeared in 8 cases. The median time to disappearance of gross hematuria was 74 days. There was no recurrence. Of the 3 ineffective patients, one had urinary diversion, and two had transurethral electrocoagulation and hyperbaric oxygen therapy. There were no adverse events associated with the use of choreitogoshimotsuto. Choreitogoshimotsuto might be effective for radiation hemorrhagic cystitis.

Background: No consensus exists regarding which anthropometric measurements are related to bone mineral density (BMD), and this relationship may vary according to sex and age. A large Japanese cohort was analyzed to provide an understanding of the relationship between BMD and anthropometry while adjusting for known confounding factors. Methods: Our cohort included 10,827 participants who underwent multiple medical checkups including distal forearm BMD scans. Participants were stratified into four groups according to age (≥50 years or <50 years) and sex. The BMD values were adjusted for confounding factors, after which single and partial correlation analyses were performed. The prevalence of osteopenia was plotted for each weight index (weight or body mass index [BMI]) class. Results: Cross-sectional studies revealed that weight was more favorably correlated than BMI in the older group (R=0.278 and 0.212 in men and R=0.304 and 0.220 in women, respectively), whereas weight and BMI were weakly correlated in the younger age groups. The prevalence of osteopenia exhibited a negative linear relationship with weight among older women ≥50 years of age, and an accelerated increase was observed with decreasing weight in older men weighing <50 kg and younger women weighing <60 kg. When weight was replaced with BMI, the prevalence was low in most subgroups classified by weight. Conclusions Weight, rather than BMI, was the most important indicator of osteopenia but it might not be predictive of future bone loss.

Objective：Patients with vertebral compression fracture first visit the acute care hospital for a diagnosis, but cannot be admitted and return home with a corset and analgesics. Because of severe lower back pain, they stay in bed for a significant period of time, and their skeletal muscles suffer from disuse atrophy. We aimed to actively admit these patients for recovery phase rehabilitation by setting up a hotline.Methods：The backgrounds of each case including the major laboratory findings were investigated for 1 year. Health professionals were able to use the hotline to request admission for the patients.Results：One hundred twenty-seven patients (38 males and 89 females, aged 84±7.5 years) were admitted. The percentages of phone calls from acute-care hospitals, clinics, and regional care managers were 46%, 31%, and 20%, respectively. With regard to degree of disability 36％ of the patients were at C1, 31% were at B2, and 20% were at C2 indicating that they needed almost complete assistance. Fifty one percent of the patients lived alone, and 20% were couples without assistance from others. Because they were elderly patients with many complications, more than six agents had been prescribed on average. However, osteoporosis medication had been prescribed to only 23%. The prognosis was favorable with ratio of returned home being 91%, even though the outcome of rehabilitation is limited by ageing and deteriorated cardiac and renal functions in these patients.Conclusion：Services to support these patients during the recovery phase of rehabilitation is crucial, in order to improve community-based health care.
