本研究では運動トレーニングによる体力向上が,アルコール分解能を高めることを実験的に検討した.日常的に運動習慣のない被験者を対象に,12週間にわたるトレーニングを行った.その前後で体力テストを行い,トレーニング効果とアルコール分解能を測定した.初年度は有酸素性トレーニングについて検討し,次年度は筋力トレーニングについて検討した.結果として,有酸素性トレーニングによってアルコール分解能は向上しなかったが,筋力トレーニングによってアルコール分解能が向上した.故に,筋肥大を伴うようなトレーニングはアルコール分解能を向上させるといえる.

The purpose of this study was to clarify the relationship between running distance over an 8-month period and both 5000 m running performance and aerobic capacity (VO2max, VO2VT, running economy). The 8-month study period was divided into two segments of 4 months each. It was found that long-distance athletes could run 5000 m in about 15 min 30 s. The analysis also confirmed the following: (1) athletes that ran longer distances in the 8-month period had better 5000m times; (2) they had higher VO2VT; and (3) athletes whose distances were longer in the first half of the study period had better VO2VT and 5000m records in the second half of the period. The anaerobic threshold reached a higher level in runners with greater training distance, resulting in an improvement in race results. Furthermore, based on the fact that the distance run in the first four months effects on VO2VT and 5000 m running times in the latter four months, this study demonstrates the possibility of training effects occurring after a certain latency period. The results implicated that it was important to track running distances as an indicator of race performance.

The purpose of this study was to compare effects of different amounts of carbohydrate (CHO) in beverage on plasma glucose (GLU) concentration during exercise after feeding breakfast. Seven healthy Japanese male subjects performed 30-min cycling at an intensity on the 75% of maximal load at 3-h after feeding breakfast under 3 types of CHO (0 g, 30 g and 150 g) beverage conditions. The subjects ingested 500 mL of beverage dissolved each amount of glucose at 30-min before the exercise. The GLU concentrations were measured at 35- and 10-min before the exercise and every 5-min during the exercise. The minimum GLU concentrations under the 30 g condition for all subjects were lower than a criterion for hypoglycemic (72 mg / dL). The mean value also fell below the criterion at from 10- to 20-min during exercise. The minimum GLU concentration under the 150 g condition of only one subject was lower than the criterion, but the mean value did not fall below the criterion. Significant negative correlations were found between the subjects’ maximum oxygen uptake (VO2max) and the decreases in GLU concentration from maximum to minimum under both the 30 g (r = -0.947, p < 0.01) and 150 g conditions (r = -0.884, p < 0.01). This study clarified that feeding breakfast at 3-h before the exercise followed by the 30 g CHO beverage ingestion at 30 min before the exercise induced exercise-induced hypoglycemia, and that the subjects with higher VO2max had the greater decreases in GLU concentration.

We examined physical fitness adaptation after six weeks of snow shovelling using different types of shovels. Thirty-three subjects participated in this study and were divided two groups: normal shovel group and less-workload shovel (UD-shovel) group. Grip strength, vertical jump, 10 m obstacle walking, chair rising test, lactate threshold and body mass were measured before and after six weeks of snow shovelling. All measurements showed no significant differences between the groups. The chair rising test and ten meter obstacle walking were significantly at main effects. These values were higher in the after period than in the before period. But there were no significant differences at main effects in grip strength, vertical jump, lactate threshold and body mass. These results suggest that six weeks of snow shovelling may not affect upper body strength and aerobic capacity, but may affect lower body and muscle of trunk strength, power, agility, balance and coordination. These effects were not different if using normal shovels or UD-shovels.

The present study aimed at evaluating effects of different daily exercises on executive function (EF) and mental health in elderly individuals. The twenty-three elderly individuals including; inactive individuals (INACT, n = 9), bowlers (BOWL, n = 8), and runners (RUN, n = 6) were studied (55-64yr). The performance of EF was evaluated by the Stroop Color-Word test. The status of mental health was assessed by the use of questionnaire. The EF was significantly higher in the BOWL and RUN as compared to the INACT. The mental health status in the BOWL was significantly better than the INACT. The present study suggests that daily regular exercises such as bowling and running improve EF in elderly individuals, and in particular BOWL showed a well maintained status of mental health.

The purpose of this study was to examine the physiological responses to intensive snow shoveling. The subjects were six males (25-71, 50±8 years) who participated in a snow removal volunteer tour. Prior to the tour, each subject engaged in a cycle ergometer test (Test 1) and a multistage shoveling test (Test 2) to evaluate the relationship between volume of oxygen consumption (VO2) and heart rate. Field measurements were performed in Miruto of Iwamizawa City, Hokkaido, Japan on February 2, 2014. Average air temperatures of that day were -6.3°C in the morning and -1.4°C in the afternoon. The snow layer at the work site had various grain shapes and snow density linearly increased with snow depth. While snow hardness increased exponentially with increase in snow depth. Mean heart rate during working time in the afternoon (142±9 beats min-1) was significantly (p<0.01) higher than that in the morning (131±9 beats min-1). These heart rates correspond 84% and 77% of the predicted maximum heart rate (HRmax), respectively. Ratings of perceived exertion were not different in the morning (12.9±0.4) and afternoon (12.4±0.3). The mean values of VO2 in the total work period (111±3 min) was estimated to be 22.2±1.2ml kg-1min-1 (Metabolic equivalent; 6.4±0.3METs). Estimated energy expenditure averaged 782±46kcal. It is conceivable that increase in snow hardness and snow density caused an increase in work intensity.
