The purpose of this study is to report the factors of circulatory disturbances in the fingers of baseball players and the symptoms of those and to investigate the incidences by the administration of a questionnaire. The respondents were 804 players belonging to clubs in junior high school, high school, and universities. According to questionnaires, 202 players (25.1%) were aware of circulatory disturbances in their fingers, and there were most replies having circulatory disturbances in the catching hand with index finger. Especially players of a position with much catching balls frequency, such as a catcher and a first baseman, seem to have the high rate of having circulatory disturbances from repetitive ball impact. No relation to their positions, the appearances of circulatory disturbances in the fingers was remarkably increased from 4 to 7 years from beginning baseball that suggested this period would be needed the device and the measure of practice method for prevent or relief from repetitive ball impact. The various factors seem to be relative causing the appearances of circulatory disturbances in the fingers, such as years of experience playing baseball, their position, their using globes or mitts, temperature, ground condition, smoking custom and so on.

Performance times of distance runners were predicted bassed on the 16-km time differential trail (2004) and 20-km grouped trial (2005) runs on the same training course before Hakone-Ekiden event. From these data, predicted and target performance times were estimated by using changes in split time (min/5km) and surplus performance for each distance runner after the trials. After the Hakone-Ekiden event, actual performance time for each distance runner was obtained and the errors (predicted performance time-actual performance time, and target performance time-actual performance time) were calculated. Errors were indices of accurate estimation of each performance time in Hakone-Ekiden event. The split time (min/5km) in 16-km time differential trial run showed large individual difference at the end of the trail. However, the 20-km grouped trial run exhibited small individual difference at 15-km and at even 20-km the deviation was relatively small. Predicted performance times were more accurate for the 20-km grouped trial run than for 16-km time differential trial run. Based on these results, 20-km grouped trial run was more suitable for to the prediction of actual performance times for distance runners in the Hakone-Ekiden event.

Sport psychiatry is relatively a new field of psychiatry which has two perspectives as follows: (1) a clinical application of sport into clinical psychiatry, and (2) an application of clinical psychiatry into sport. In this article, I demonstrate two cases with depressive disorder and anxiety disorder who were successfully treated with aerobic exercise, then discuss clinical applicability of sports/exercises into clinical psychiatry with literature review. Several clinical studies with RCT design have revealed that sports/exercises were effective for depressive disorders as well as pharmacotherapy and cognitive therapy. Similarly, literature review revealed that sports/exercises were effective also for anxiety, although by less well-designed studies. In conclusion, sport therapy is just complementary to traditional therapies such as pharmacotherapy and cognitive therapy for anxiety and/or depressive disorders.

The purpose of this study is to elucidate the energy metabolism in a simulation of the fifth section of the Hakone Ekiden(disrance of 20.7km)using a runner-motion-response-type treadmill in a laboratory. Five male runners aged 20.2±.6 years were asked to run at their desired speds on a programmable treadmill whose"slope-setting"was changed automatically every fifty meters. The runners watched a video of the acrual course during this experiment. We found a significant correlation between the slope every fifty meters and the mean step length(r=-0.695)and step frequency(r=0.646). The mean values of oxygen uptake and respiratory exchange ratio of the five runners were 59.83±5.42(range 56.35-62.55)ml/kg/min and 0.99±0.05(range 0.97-1.01), respectively. The total energy expenditure and energy expenditure deduced from carbohydrates and lipids in this fifth section were 1632±58 kcal, 1502±120 kcal, and 130±96 kcal, respectively. In the case of an upward slope, we observed a significant correlation between energy expenditure(kcal/kg)for the five runners and mean step length(r=-0.942), mean step frequency(r=0.918), and running time(r=0.982). These results indicate that about 90% of the total energy used in the fifth section is supplied by the carbohydrate component and showed the high intersity of exercise during this section. In conclusion, our results for the upward slope showed that good long-distance runners use a longer step length, and thereby save energy and thus realize an improved running economy.

スポーツが原因で生じる外傷に対し、その予防法を確立するためには、骨組織の衝撃破壊特性を明らかにすることが必要である。破壊じん性試験は、準静的から高速領域のひずみ速度下でウシの骨から採取されたコンパクトテンション試験片を用いて実行した。骨の破壊機構は繊維強化複合材料のモデルを用いて検討した。二つの仮説を証明するために破断面の走査型電子顕微鏡による観察を実施した。我々の提案は以下の通りである。湿潤骨試験片の線維強化機構は、ひずみ速度によって、ブリッジング、プルアウトそして線維強化無効の3つの領域に分けられる。マイクロクラック強化機構は高速負荷領域ε=1.2×10^2_s^<-1>において母相に働く。

The purpose of this study is to investigate the effect of artificial carbon dioxide-rich water for peripheral circulatory improvement on fingers of baseball players with circulatory disturbances catching hands with index fingers suffering from repetitive ball impact. A trial therapy of bathing in artificial carbon dioxide-rich water and fresh water for following the nine university baseball players having symptoms of circulatory disturbances graphic evaluation of thermograph and analysis of temperature on fixed point was done. Results suggest circulatory improvement of fingers : two players of the artificial carbon dioxide-rich water tended toward increased temperature on their catching hands, indicating improved blood flow in the index finger and center-point of the palm area. The measurement conditions were not always ideal because there were some variance in this trial therapy, for example environmental temperatures, degrees of circulatory disturbances, problem progress of bathing and so on ; nevertheless treatments for circulatory disturbances in the fingers under the condition of low temperature don't currently exist. The therapy of bathing in artificial carbon dioxide-rich water seems to be useful on the sports field.

Although carbon dioxide had an increase action of a skin blood flow, a blood-pressure fall action, etc. to the human body, in order to utilize these actions for conditioning of Athlete, experiment using carbon dioxide-rich water produced artificially was performed. The upper limbs of both sides were immersed in artificial carbon dioxide-rich water and fresh water which were set up lower than the temperature of a human body and comparison examination of the recovery process of the skin temperature of since it is immediately after taking out from water was carried out by fresh water and artificial carbon dioxide-rich water. In five healthy adults who do not have trouble in the blood circulation of a finger, subjects are two men and three ladies. A temperature set up three temperature belts, 15 degrees, 20 degrees and 35 degrees, and immersion time was performed in 5 minutes, 10 minutes, and 20 minutes, and observed the recovery process of skin temperature in thermometer. Three fixed points were established in observation of skin temperature and three points, a middle finger tip, mid-palm, and distal portion of forearm, were made into the viewpoint. Result: The early recovery tendency of skin temperature after immersion was seen to carbon dioxide-rich water between fresh water and carbon dioxide-rich water. Further the skin temperature of the portion immersed in carbon dioxide-rich water from immediately after immersion showed the tendency higher than the skin temperature of portion immersed in fresh water and which becomes large as it went to the tip, and the temperature of the portion dipped in carbon dioxide-rich water from immediately after immersion was the largest at the middle finger, and showed the small tendency by distal portion of forearm Moreover, the difference may not be seen in recovery time of skin temperature, by evaluation with thermometer. When both upper limps were immersed to the water set as 35-degree, recovery of skin temperature happened for a short time and the difference of recovery of skin temperature showed the few tendency in the comparison between fresh water. Consideration: The increase effect in a skin blood flow which carbon dioxide has also in artificial carbon dioxide-rich water was observed, and it was thought that it was utilizable for maintenance of condition of Athlete or rehabilitation. However, there is also a case from which the increase effect of a skin blood-flow was not acquired, and it was thought that examination was required further.

The purpose of this study was to examine the relation between the degree of anxiety and the sway of the center of gravity in the standing posture. Subjects were 58 undergraduates. Both state anxiety and trait anxiety of each subject were assessed by the STAI test. The sway of the center of foot pressure in the standing posture for 20 seconds was measured as postural sway by a stabilometer. Results were as follows : (1) The average magnitude of sway of the high trait anxiety group was significantly larger than that of the low trait anxiety group. On the other hand, such finding was not found in state aniety. Postural sway was related to trait anxiety rather than to state anxiety. (2) Such relation was detected not in the postural sway with eyes open but in that with eyes closed.

The purpose of the present study was to determine the effects of a resistance training program in triathletes. Eight healthy university competitive men's triatheletes who had no experience of the resistance training were assigned to either the resistance training group(TRAINING : N=4)or the regular training group(CONTROL : N=4). The resistance training program that Johnston et al.(1995)used for women long-distance runners was carried out three times a week, for ten weeks in TRAINING. Body weight, body fat, muscle cross-sectional area of thigh, squat 1RM, leg press power, isokinetic strength, and the incremental exercise using treadmill were examined before and after the training. At the same time, VO_2max and blood lactate concentration were also measured. The main results were as follows; 1) In regard to body weight, body fat, and muscle cross-sectional area of the thigh, no significant changes were found in either the TRAINING a CONTROL groups. 2) In the case of squat 1RM and leg press power, a significant increase was noted in the TRAINING group (p<0.01,p<0.05). There were no significant changes in isokinetic strength for either the TRAINING or CONTROL group. 3) There was no significant changes in VO_2max/BW in either groups. However, there was a significant increase in blood lactate concentration in the TRAINING group (p<0.05). 4) There was a positive correlation between the percentage change in leg press power/squat 1RM and in blood lactate concentration (p<0.05)in both groups. From these results we suggest that the resistance training program in triathletes was useful to improve the muscle strength and power without muscle hypertrophy, and to enhance during endurance high intensity exercise.

In order to study the claracteristics of a Judo athlete's muscle strength, regulated measurements of both leg/knee extension and leg/knee flexion strength were taken with use of a Isokinetic Muscle Contraction Weight Machine and then compared and studied for each weight category. The following conclusions can be deduced from the consequent results. 1) The value of peak torque decreases in proportion to an increase in the speed of movement. 2) The value of power increases in proportion to an increase in the speed of movement. 3) The value of peak torque together with power increases with the increase in weight ategory (light to heavy). 4) If one looks at te different values of peak torque per weight as well as power per weight within each weight category, the +95kg group shows a significantly smaller speak torque and power value than any other weight category. No significant difference could be observed through out the different weight categories when peak torque and power values of the lean body mass (LBM) of each weigth group were taken.

The purpose of this study is to obtain some basic data on the judogi chin-up training method for improving women judoists KUMITE strength and the testing method for determining its effectiveness. The subjects in this study are women collegiate judoists, concerning whom the number of chin-ups from a suspended judogi was measured. Also examined was the relationship between those results and the practitioners body shape, weight class and other physical strength measurement results along with the technical characteristics of their judo skills. The findings are as follows : 1) The average measurement value of their judogi chin-ups was 5.0 ±3.0 times which was 31 % of men's reported in the past. 2) There was a significant negative correlation between the measurements of their judogi chin-ups and their weight, but there was no significant correlation between the measurements of their judogi chin-ups and their body fat percentage. 3) Regarding the average measurement value of judogi chin-ups by rankings, the average for light weight class was significantly higher than that for middle weight class, and the average for middle weight class was significantly higher than that for heavy weight class. 4) There was a significant positive correlation between the measurements of their judogi chin-ups and their number of chin- ups from a regular bar. But there was a significant negative correlation between the measurement's of their judogi chin-ups and their strength of grip. 5) There was a significant negative correlation between the measurement of their judogi chin-ups and their 1RM of power clean, but there was a significant positive correlation between the measurement of their judogi chin-ups and their 1RM weight ratio for bench press. 6) The measurements of the group of right-hand KUMITE chin-ups tended to show greater values than those of left-hand KUMITE chin-ups. It implied that there was a positive correlation between features of KUMITE and judogi chin-ups. 7) There was no significant correlation between the measurements of their judogi chin-ups and their rankings and records in judo.

1. Purpose We intended to grasp the mental conditions of Hakone-Ekiden Athletes in Tokai University teams. Recently, in sports world it is important to maintain mental condition rather than physical condition. In this paper, we made a comparative study of the investigations in 1988 and 1990. 2. Procedure 1)Tests (1) Uchida-Kraepelin Psychodiagnostic Test (U-K Test) (2) Yatabe-Guilford Personality Inventory (Y-G Test) 2) Subjects Tokai University teams of Middle and Long-distance blocks. (1) Regular groups; 13 athletes (2) Semi-regular groups; 7 athletes 3) Testing term and place December, 30,1990,9 : 00AM. At Tokai University, Shonan Campus. 3. Results 1) U-K Test The result of the analysis showed that the characteristics of the personalities of athletes are full of variety. No.5 Type -8 athletes, No.10 Type-4 athetes, No.4 Type-3 athletes, No.6 Type-2 athletes, 3-1d Type-2 athletes and No.2 Type-1 athlete. 2) Y-G Test The result of the analysis showed that D Type-9 athletes, A Type-4 anthletes, E Type-4 athlletes, C Type-2 athletes and B Type-1 athlete. 3) Mental health The result of the analysis showed that the mental health of the athletes in the regular group and in the Sem-regular group are in the similar degree. 4. Conclusion By two investigations in 1988 and 1990,we guess that we had better select representative athletes with a high degree of mental health and a high fucuturation rate in the latter period.

1. Purpose We intended to grasp the mental conditions of Hakone-Ekiden Athletes on Tokai University teams. Up to this time, the regulation of physical conditions of athlete has been comparatively, easy to put into practice. But we are not able to establish a definitive method to regulate the mental condition at the present. By the investigation mentioned below, we wanted to contribute to explain the mental condition of athletes and applied the results of this investigation to the selection of representative athletes for Hakone-Ekoden. 2. Procedure 1) Tests (1) Uchida-Kraepelin Psychodiagnostic Test. (2) Yatabe-Guilford Personality Inventory. 2) Subjects Tokai University teams of Middle and Long-distance blocks. (1) Regular groups : 14 athletes (2) Semi-regular groups : 14 athletes 3) Testing term and place December, 31,1987 At Tokai University, Shonan campus in Matsumae-kaikan. 3. Result 1) Mental health The result of the analysis showed that the mental health of the regular group is higher than that of the Semi-regular group. 2) U-K Test The results of the analysis showed that the characteristics of the personalities of athletes are full of variety. No.5 Type-7 athletes and 3-1 Type-4 athletes is a notable result. 3) Y-G Test The result of the analysis showed it remakable that D Type is to be 15 athletes in 28 athletes. 4. Conclusion 1) We selected a representative athlete with a high degree of mental health and a low fluctuation rate of the latter period. 2) The selection of the representative athlete for No.4 block failed 3) It can be pointed out that the most remarkable feature of an athlete found to be in bad condition is that the work efficiency dropped for 12-15 minutes of the latter period of the Test.
