DEVELOPMENT OF EQUIPMENT FOR ESTIMATING SWIMMING POWER

INTRODUCTION: In previous studies on this topic, the methods of measuring swimming power during swimming were examined. Costill et al. (1983) developed the method of evaluating swimming power by improvement of the biokinetic swim bench. It was suggested that swimming power is one of the more important components of the sprint swimming performance. However, it was difficult to apply the equipment for measuring swimming power to the swimming training, because the equipment for measuring this was complex. Therefore the purpose of this study is to develop simple equipment for estimating swimming power

Training intensities for aerobic exercise determined on untrained healthy men.

The purpose of this study was to determine the aerobic training intensity from the maximal and submaximal running exercise in 21 untrained adult men. To accomplish this, we evaluated the relationship between physiological (oxygen intake and heart rate) and physical parameters (running speed) of training intensity, and determined the training intensity at the submaximal exercise. Oxygen intake and heart rate were measured by a treadmill test. The maximal oxygen intake (VO2 max), and the aerobic threshold (AerT) and anaerobic threshold (AT) were measured to determine respiratory gas exchange. Running capacity was measured by a 12-min running and treadmill test. For the maximal exercise, there was a significant correlation (r = 0.88, P &#60; 0.01) between VO2 max and 12-min running distance (speed). In addition, the oxygen intake and heart rate at AerT and AT in the submaximal exercise were linearly correlated with running speed. Three levels of training intensity at the submaximal exercise were termed: light, moderate, and heavy. Since AerT was the lower limit intensity and AT was the upper limit, we took the middle of their values as the moderate intensity. The end point for the determination of the training intensity at the submaximal exercise was estimated to be 85% VO2 max and 180 beats.min-1.</p

パワーリハビリテーション・マシンによる中・高年者の初期負荷値設定について

The objective of this study was to clarify the appropriate individualized initial intensity of muscle training on a Power Rehabilitation(PR) machine for middle-aged and elderly people from its relationships with the skeletal muscle mass and muscle strength (grip strength). The subjects were 50 males and females (mean age 63 years, range 43-79 years) participating in a PR fitnesss course. Seven training events were performed on the PR machine. The initial training intensity in these events showed considerably high correlations with the skeletal muscle mass (r=0.42-0.57, p<0.05) and grip strength (r=0.43-0.61, p<0.01). However, when regression equations were calculated, the level of significance was p<0.05 for grip strength, suggesting that the initial training intensity can be determined according to the grip strength. Also, as the perceived exertion scale (Bprg\u27 s scale) presently used for PR was originally an index of general endurance, a new scale of perceived exertion concerning weight loading is proposed

フィンランド共和国カヤーニ応用科学大学との国際交流に伴う視察報告

The purpose of this report is to find possibilities of promoting the international exchange with Kajaani University of Applied Sciences. We visited the Republic of Finland from 3rd June, 2006 to 10th June, 2006. We tried to collect much information about the necessity of promoting the international exchange in two points of views, that is, the environmental information and the internal information of Kajaani University. As a result, Kajaani University has the good environment to learn sports and social welfare because of the cooperation between other universities, sports organizations and organizations related social welfare. Kajaani University also has the good internal system for students to learn sports and social welfare because of easy access to sports facilities and research institutions related social welfare
