Effects of buoyancy aids on heart rate and swimming performance in beginning swimmer
Get PDFSwimming is an exercise in which one’s body moves above or under water. Additionally, it is affected by buoyancy and gravity because the swimmer moves horizontally. If the distance between the center of buoyancy and gravity increases, underwater torque generates, sinking the legs; thus, swimming performance is reduced. Therefore, beginner swimmers allow their legs sink. In this study, technical training was provided for beginner swimmers wearing buoyancy aids that bring the center of buoyancy closer to the center of gravity to determine the effects of wearing buoyancy aids on the heart rate, swimming performance, and perceived exercise intensity in measuring swimming performance. Buoyancy aids, such as a pool helper (N) and swim balancer (N), which are often used in the early stages of swimming instruction, were used. The paired t-test showed no statistically significant differences between the two aids. Although some articipants were unable to swim 25 m, they did not stop swimming, suggesting that the buoyancy aids may have contributed in improving the swimming ability. The study results suggest that buoyancy aids may help improve the swimming ability of beginner swimmers, although there was no difference in physiological and wimming performances between the two buoyancy aids.departmental bulletin pape

Learning content, teaching methods, and satisfaction perceived by learners who have experienced judo classes at junior high and high schools
Get PDFThis study clarified the reasons university students who experienced judo classes in junior
high or high school liked and disliked the content and method of teaching judo at that time.
The subjects were university students in the faculties of physical education, education, and
sports in the Kansai area who had experienced judo classes as aforementioned. The results
revealed the following.
1. Randori was the most popular judo lesson (70 students, 33.3%). The main reason was that it
was fun to freely attack and defend against opponents using the techniques they had learned
(53 students, 76.8%).
2. Ukemi was the most common reason given for disliking judo (49 students, 36.6%). The main
reason was that it was not fun (24 students, 49.0%).
3. The learners were most satisfied with the teachers’ judo instructional methods because they
provided clear examples (36 students, 22.1%), and they were most dissatisfied with the lack of
step-by-step instruction (11 students, 25.6%).
4. Most learners (74-87%) were satisfied overall with their judo classes in junior or high school.
It was suggested that it is important to have flexible ideas and to work to improve the
content of learning and unsatisfactory teaching methods in judo. In addition, better judo classes
should be constructed by paying attention to what learners disliked and were not satisfied with.departmental bulletin pape
Developing Three Japanese Physical Education Scales About Competency with Junior High School Students of Grade3 and High School Students of Grade1 in Japan
Get PDFThis study aimed to develop three Japanese physical education scales to assess competency
of junior high school and high school students of Grade 3 and 1, respectively, in Japan. Results
revealed the following aspects: 1) “Japan Physical Education Evaluation Scale of Knowledge
and Skills (JAPEES-KS-J3&H1)” comprised four factors with a total of 11 items :“ Enjoyment of
Physical Exercise,”“ Knowledge of Physical Exercise and Safety,”“ Skills. of Physical exercise,”
and “Knowledge of Physical Exercise and Physical Fitness”; 2) “Japan Physical Education
Evaluation Scale of Think, Make Judgements, and Express (JAPEES-TJE- J3&H1)” comprised
three factors with a total of nine items: “Judgement and Expression of Physical Exercise
Method,”“ Thinking and Judgement of Physical Exercise,” and“ Judgement and Expression of
Physical Exercise Problem Solving with Reason”; 3) “Japan Physical Education Evaluation
Scale of Cultivate the Motivation to Learn and Humanity (JAPEES-CH- J3&H1)” comprised
four factors with a total 10 items : “Responsibility and Equity of Physical Exercise,” “Live
Together of Physical Exercise,”“ Health and Safety of Physical Exercise,” and“ Cooperation of
Physical Exercise”; 4) Reliability of the developed scales was confirmed through Cronbach
alpha and test-retest correlations, and validity was confirmed by criterion-related and structural
validity.departmental bulletin pape
Investigation of Judo MIND Comprehension and Competence Improvement among High- School Student
Get PDFThe purpose of this study was to verify how well high-school judo club members understood
Judo MIND and how much they felt their ability had improved. A questionnaire was
administered to 154 high-school judo club members to evaluate their understanding of Judo
MIND and the extent to which they had improved their ability in Judo MIND. The results
revealed the following:
1. 60-70% of the participants did not understand“ M,”“ I,”“ N,” and“ D.”
2. Regarding their ability in Judo MIND, high-school students felt that their ability in“ M”
had improved more than their ability in “N” and in “D.” The high-school students also
felt that their“ I” ability had improved more than their“ D” ability.
The above findings highlight the need to fully explain the meaning of “I,” “N,” and “D,” in
particular, in order to spread the ethos of Judo MIND among future high-school students.departmental bulletin pape
