Résumé
Stretching for the triceps surae muscle in the knee flexed position (medical stretching: MS) and knee extended position (static stretching: SS) were performed and the effect on the dorsiflexion angle of the ankle joint was examined. Five elderly females were selected as subjects. We measured the maximal dorsiflexion angle of the ankle joint in the following leg positions: (1) the maximal dorsiflexion angle in the extended knee position (EDF angle) and (2) the maximal dorsiflexion angle in the 90°flexed-knee position (FDF angle). There was a significant increase in the maximal dorsiflexion angle after MS and SS were carried out (p<0.01), but there was no significant difference between MS and SS. It was concluded that MS for triceps surae is equally effective as SS in increasing the maximal dorsiflexion angle of the ankle joint.

<p><b>BACKGROUND</b>There are few longitudinal studies on the associations of obesity with hypertension in young adults.</p><p><b>OBJECTIVES</b>To analyze longitudinally to what extent weight gain associates with hypertension in young adults.</p><p><b>METHODS</b>The subjects of this study consisted of 6,178 university students (male 4,098; female 2,080). The associations of hypertension with body type change were longitudinally examined by using the records of health examinations while at university. The prevalence ratios (PRs) for hypertension in their senior year were calculated on groups that changed toward obese against those that changed toward underweight. The logistic regression analyses were used to estimate odds ratios (ORs) for hypertension in their senior year of each factor. The analyses were conducted on (i) all subjects, (ii) non-hypertensive subjects in their freshman year, and (iii) by schools, in order to take into account physical activities.</p><p><b>RESULTS</b>The PRs of hypertension in subjects changed toward obese from their freshmen to seniors against ones toward underweight were 1.47 (95% CI; 1.00-2.15) for males and 3.50 (0.93-13.22) for females. In analyses limited to non-hypertensive subjects in their freshman year, results were similar to those of all subjects. The analyses by school also showed similar results to those including all subjects. In logistic regression analyses, although the factor most strongly associated with hypertension was body type in their senior year, the body type in their freshman still showed significant association with hypertension after the adjustment of senior year body type and hypertension in freshman year. The ORs for hypertension in obese subjects to normal weight ones in their senior year were 9.13 (95% CI; 5.77-14.45) for males and 22.59 (5.69-89.67) for females after adjusted by hypertension in freshman, body type in freshman and school.</p><p><b>CONCLUSIONS</b>These data suggest that the increase of BMI is linked to hypertension in university students.</p>
Résumé
A study was conducted to clarify the occurrence of injuries among Japanese and Korean handball players, their present condition, and the response to prescribed treatments. It was also ascertained whether players, after receiving proper treatment, were less susceptible to injury sequelae. A questionnaire was delivered to Japanese and Korean company handball players totaling 244 women (8 Japanese teams, 136 women ; 7 Korean teams, 108 women), during the period from December 1996 through March 1997.<BR>The rate of injuries and the treatment situation during and after the period when the injury was sustained, and the occurrence of sequelae in the lower limbs after the player had joined the team, were examined, and a comparison between the two countries was made. The return rate was 88.9%.<BR>1. The emergency treatment rate after injury was similar in the twe countries. However, Japanese players usually used taping and cooling, whereas Korea players used heat treatment. 2. Both Japanese and Korean players' injuries were diagnosed at hospital, although Koreans also went to bonesetters. 3. Japanese players resumed playing upon receiving their doctors' consent, whereas some Korean players were forced to resume playing before fully recovering ; there was a significant difference between the two countries. 4. Many players in both countries, resumed playing even though they felt pain in daily life. 5. Players who had undergone cooling treatment immediately after the injury, and who resumed activities upon their doctors' consent, and only after the pain had disappeared during daily life, had a lower incidence of sequelae.
Résumé
The purpose of this study is to obtain more information about the occurrence of sports injury and through this to prevent injury in handball players.<BR>Aquestionnaire was delivered to Japanese and Korean company handball players totaling 244 women (8 Japanese teams, 136 women and 7 Korean teames, 108 women), during the period from December, 1996 through March, 1997. The return rate was 88.9%. Injury rate in Korean teams was 73.2% and 71.7% in Japanese teams ; no statistical differences were found among these two countries. The injury rate was high on ankle joint, knee joint and lumbar in that order. Korean teams presented higher occurrence of jumper's knee and stress fracture.
