幼児における疾走能力の分析<教育科学>
Get PDFThis study investigated the biomechanical analysis of sprinting performance for preschool children. The subjects were 77 preschool children who aged 3 to 6. They were filmed in VTR picture during 25m sprinting, with a pole located every 5m. Using the VTR pictures, average speed; stride frequency; stride length between the start point and the marked distance point of each were calculated. The results obtained were as follows:
1 The sprinting velocity cause by height, and by stride length in preschool children. On the other hand, stride frequency is not related to height.
2 It was suggested that the sprinting velocity was greatly related to stride length and stride length ratio, and also weakly related to the stride frequency.
3 Times of 25m sprinting were decreased from 3 to 5 years for both boys and girls.
4 It was suggest that both boys and girls reached the highest for sprinting velocity in the 5-20m section, and the decrease in sprinting velocity decreased for the stride frequency after 10m and for the stride length after 15mtextapplication/pdfdepartmental bulletin pape
病棟の騒音に対する環境音の効果
Get PDF病棟で発生する騒音に対する環境音の影響を実験によって調べた．その結果，対象となった騒音は，うるささは強くはないものの，不快な音として被験者に認識されており，すべての環境音よりも不快感が高かった．騒音に対して環境音を同時に被験者に提示した場合については，一部の環境音が騒音に加わることにより，うるささが高まった．しかし一方で，ししおどし，シジュウカラ，ウグイス，エンマコオロギ，風鈴（鉄）の音を騒音に加えることにより，騒音のみが聞こえる場合よりも快適さは高まり，環境音が騒音に対して効果的に働く可能性が示唆された．Article信州公衆衛生雑誌 6(1): 60-61(2011)journal articl
小学生陸上競技大会100m走の検討<教育科学>
Get PDFThis research analyzed 100m race from the third grade to the six grade of elementary school for 64 people. They were filmed in VTR picture during 100m race. Using the VTR pictures. We calculated average speed. stride frequency and stride length. The results obtained were as follows: 1 The average speed of the girl had increased up to 6.668m/s at the 6th grade from 5.687m/s at the 3rd grade and of the boy had increased up to 6.862m/s at the 6th grade from 5.959m/s at the 3rd grade. The difference has not seen for the stride frequency. Girl's stride length has expanded up to 1.667m at the 6th grade from 1.404m at the 3rd grade. and boy's stride length has expanded up to 1.678m at the 6th grade from 1.450m at the 3rd grade. As for the girl. the stride length of the 4th grade is longer than the 3rd grade. and the 5th grade is longer than the 4th grade. and the 5th grade and the 6th grade has not seen significant. As for the boy' s stride length. the 3rd grade and the 4th grade. and the 4th grade and the 5th grade have not seen significant. And the stride length of the 5th grade is longer than the 3rd grade. and the 6th grade is longer than the 3rd. 4th. 5th grade.
2 The highest speed of the boys in the 5th grade was 7.207m/s. and of the boys in the 6th grade was 7.644m/s. The highest speed of the girls in the 5th grade was 7.063m/s. and of th girls in the 6th grade was 7.550m/s.
3 When the decreasing rate has seen. the speed has lost 9.3-12.7%. the stride frequency has lost 7.6-12.5%. and the stride length has lost 2.4-4.3%. The decrease at the speed is suggested dependence on the decrease in the stride frequency.
4 If the maximum speed maintenance section was assum d until 2% decrease. the girls in the 3rd grade was 1O-30m section. the boys in the 3rd grade was 20-40m section. the boys and girls in the 4th and 5th grade were 20-50m section and the boys in the 6th grade was 20-60m section. The highest speed maintenance sections were four sections and the top athlete's speed decrease was about 7%. Based on these findings. the distance of sprint race was about 70m for boys and girls in the 3rd grade of elementary school. about 80m for boys and girls in the 4th and 5th grade. and girls the 6th grade. about 90m for boys in the 6th grad.textapplication/pdfdepartmental bulletin pape
腰角増大の操作が生み出すマット運動の系統的な学習 : 小学校体育の授業における合理的で効率的な技の習得に向けて<教育科学>
Get PDFThis study investigated the effects that a cartwheel will give a forward roll and a backward roll, rationality and efficiency to learn from a cartwheel, when thinking of the connection of the tricks from the movements to widen the angle between the upper body and the legs.
1 To learn a forward roll next to a cartwheel makes a forward roll that has a large angle between the upper body and the legs in short learning time. The movements to widen the angle between the upper body and the legs of a cartwheel are transferred a forward roll. So there is a connection between a cartwheel and a forward roll.
2 To learn a backward roll next to a cartwheel improves a backward roll and makes a backward roll that has a large angle between the upper body and the legs in short learning time. The movements to widen the angle between the upper body and the legs of a cartwheel are transferred a backward roll. Especially, for children who can not do a backward roll to learn a backward roll next to a cartwheel is very effective. So there is a connection between a cartwheel and a backward roll.
3 For children who have little experience of Floor Exercises to learn a forward roll or a backward roll next to a cartwheel promises to master the tricks rationally and efficiently. So this is a systematic learning that centralizes different lineages by setting the movements to widen the angle between the upper body and the legs as key skills.textapplication/pdfdepartmental bulletin pape
中学生の投能力向上を目指したサーキットトレーニングの影響<教育科学>
Get PDFThis study examined the influence on “the ball throwing ability” by doing the circuit training partially of the physical education class. The circuit training of eight items was done at nine hours in total of three times a week and three weeks in November. Every time, it took about 14 minutes from 12 minutes to the circuit training. The subjects were 90 junior high school (42) boys and (48) girls. The results obtained were as follows:
1. The student who improved the record of a ball throwing was 88.1%, and the student who did not improve the record was 11.9% by the circuit training for boys.
2. For girls, the student who improved the record was 66.7%, and the student who the record did not change was 16.7%, and who decreased the record was 16.7%.
3. The ball throw distance became as 23.83m from 21.76m for boys and 15.56m from 14.42m, and showed a significant expansion statistically respectively.
Based on these findings, there were a lot of students who improved the ball throw distance because of the circuit training as a part of the physical education class.textapplication/pdfdepartmental bulletin pape
