This study aimed to qualitatively and quantitatively clarify characteristics of gymnasts that resulted in the interruption of a routine at the College Student Trampoline Championship. The subjects comprised all 166 athletes (86 males and 80 females) who participated in the 41st All Japan College Student Trampoline Championship held during August 25-27, 2006. Official meeting records (score sheets and digital videotapes) were used. Based on the score records and VTR images of all athletes, subjects were divided into the success group those who completed 10 elements) and the interruption group. In addition, the average point reduction and average difficulty points of all athletes were calculated separately for each gender and class. Furthermore, the element that was interrupted, the circumstances for the interruption, and the preceding skills and circumstances responsible for the interruption were extracted from VTR images. The extraction was carried out by experienced official judges. In male voluntary routines, those who experienced an interruption had performed significantly more difficult routines in all classes combined (p<0.05), and the interrupted skills were often those with relatively low difficulty points. In females, a number of athletes in class B experienced an interruption, and those who could not complete compulsory routines experienced an interruption in voluntary routines at a significantly higher rate (odds ratio, 2.5; 95% CI, 1.2-5.3), and their scores were low. Basic skills other than feet, such as back and front, were often interrupted in class C. Taken together, it was suggested that to avoid interruption, repeatedly practicing relatively easy basic skills and continuous skills was necessary.

サクソフォン, ピアノ演奏と上下振動刺激を同時に行う「音楽運動療法」を, 脳卒中後3年間意識障害が続いている患者に行い, 健常若年者を対照にして, その有効性を検討した。10秒ごとの左右脳活動電位のパワーの変動, 1分ごとの心拍変動周波数解析による交感神経活動度LF/HF比, および心地よさの指標として1/fゆらぎを数値化したもので医学的に検討し考察を加えた。この患者では音楽実演奏のα波中心の脳波活動電位パワーポテンシャルに対する影響が異なり, 健側脳に鎮静的に, 患側脳に刺激的に, またが健側脳に刺激的に, 患側脳に鎮静的に作用し, さらに演奏の併用でこの反応を異にした。しかし, いずれにせよ実演奏と時には1/fゆらぎを来しており, 心地よい気分にあることを示し, 交感神経活動度が本療法反復により次第に活発な変動を来すようになったことで, 脳障害に対する本音楽運動療法が脳・自律神経機能賦活活性化に効果あることを実証した。
