身体へのフィット性の高いウェイトジャケットを用いて,全力疾走を行い,その時のスピード,ストライド,ピッチの変化を知り,それらとパワー,筋力の関係から,スプリントトレーニングにウェイトジャケットを用いる際の留意点を明らかにすることを目的に本研究を行い,次のような結果を得た。1)スピードは負荷重量を増すに従い低下するが,ストライドよりもピッチの低下が大きい。2)パワーは体重当たりパワーとスピードの相関が認められる。3)等速性筋力は脚の屈曲の筋力とスピードの相関が認められ,とりわけピッチとの相関が高い。4)全力疾走のためのウェイトジャケットの重量は,体重の3%から5%が適当とされているが,本研究では4kgよりも2kgの方が適していると思われる。5)ウェイトジャケットをスプリントトレーニングに用いるには,ピッチを低下させないように努力することにより,パワー向上のみではない効果が期待できるものと思われる。本研究の要旨は日本体育学会第38同大会において発表した。

The Bulgarian Women's Team received a perfect score in both composition mark and execution mark components of their team performance in the final round of the 12th World Rhythmic sports Gymnastics Competition in 1985. Both the Soviet Union and the People's Republic of Korea teams, the runner-ups to the Bulgarians, also received perfect scores in the composition of their team performances in the final round. Since the perfect 10 has been increasingly awarded in individual competitions as well as in team competitions, the purpose of this study was to determine the meaning of this score in the composition component. The first three teams, Bulgaria, Soviet Union, and People's Republic of Korea, were selected to be reviewed in this study, along with the Japanese team, (the sixth). Videofilms taken at the 12th World Rhythmic sports Gymnastics Competition were used in analyzing the performances of these four teams-The following elements of the performances were analyzed: (1) team formation and time duration of performance. (2) exchanges of apparatus and difficulties. (3) technical contents body technique and order of technique by apparatus. It was found that the Bulgarian team had the fewest number of exchanges of apparatus of all four teams. However, the Bulgarians showed a variety of new ideas in formation changes and exchanges of apparatus. The Soviet Union had the highest number of and many different types of exchanges of apparatus which were evaluated as Superior Difficulties techniques. Moreover, each Russian gymnast executed very difficult body technique . The Koreans emphasized manuevers using the feet and acrobatic techniques in their performance. Although these three teams received the ten points in composition, the judges seemed to award this score on the basis of different composition aspects. In order to receive a higher score in composition on the basis of the "Code of Points", it was assumed that not only many variations in formation changes and new ideas of exchanges of apparatus were required, but also that originality had to be emphasized. Since only a few points could be ascertained from the video film reviews in this study, further research studies would be more helpful for a better understanding of Rhythmic sports Gymnastics competitions.
