    「氷上の格闘技」と呼ばれるアイスホッケーの試合中に,パックが頸部に衝突し,心肺停止で搬送された症例を経験したので報告する。症例は18歳の男性。アイスホッケーの試合中,相手のシュートで放たれた硬質ゴム製パック(重量約160g)が左耳後部に当たり,意識消失した。直後は自発呼吸があったがまもなく消失し,救急車内収容後に心静止となった。当院に搬入された際は心肺停止状態であり,瞳孔は散大し対光反射は消失していた。CPRを継続し,エピネフリン 1 mg投与後,自己心拍が再開した。左乳様突起尾側部に打撲痕が認められた。CT及びMRIを撮影したところ,くも膜下出血及び脳幹周囲血腫を認めた。自発呼吸,意識は回復しなかった。集中治療室に入室し,脳保護目的で低体温療法を行ったが,第 5 病日のCTでは低酸素脳症の所見であり,脳波・聴性脳幹反応ともに平坦であった。遠征中の事故であったため第 7 病日に地元病院に転院搬送となったが,搬送 7 日後に肺炎による呼吸不全を主とする多臓器不全により死亡した。アイスホッケーでは身体接触による外傷のほか,スケート,スティックやパックなどによる外傷も多数報告されている。そのため若年者ではより厳重に防具で身体保護を行っているが,シュートは成人で120-150 km/hにもなる。今回は防具の隙間に衝撃が加わり,脳幹周囲出血及びくも膜下出血を呈し,脳圧上昇によって脳幹が圧迫され,呼吸停止から心停止に至ったと推測される。同様の事故による複数の剖検例も報告されており,今後防具等の改善を検討する必要がある。

        The aim of this study was to examine visual search behavior of experienced basketball players when they rebound a basketball by using an eye-movement registration system. In basketball games, the possession of the rebounding ball provides one of the most important statistical data needed to win games. In order to get the rebounding ball, the player is required both to perceive temporal and spatial information through a complex visual field and to react to an opponent player immediately. Therefore, the seven male subjects’ experimental task was to block, or so called “box-out,” the opponent offensive player under 3 randomized tactical plays in basketball 3-on-3 situations. Subjects’ athletic careers ranged from 8 to 12 years (mean ± SD : 9.70 ± 1.50 years) . A subject, a defensive player, was fitted with an eye-tracking device (EMR-9, NAC Inc.) to acquire his viewing point for the detection of visual search behaviors. Subjects’ kinematic data was also captured by 3 video cameras (S21, CANON, 60Hz) . The results showed that experienced players could react to the opponent player before the shooter’ s ball release timing quickly, almost without viewing the shooter. Experienced players showed constant fixations, fixation duration and fixation locations before the shooter released the ball, and the distribution of experienced players’ viewing points was set at a spatial area between the shooter and the opponent player under 3 tactical plays. These results indicated that experienced players utilized the properties of an ambient vision system immediately for receiving visual information broadly in order to coordinate their actions ahead of the shooter and the opponent player action under the tactical situation. An effective visual search behavior is therefore an important factor in improving quick action in this task constraint.

    The present study examined the differences in anticipatory performance and visual search strategy between skilled and novice soccer players. Fifteen skilled and 10 novice soccer players participated in the experiment. Their anticipatory performance was evaluated using a temporal occlusion paradigm. Both groups looked at film clips that had been recorded on a soccer field including only one offender (1 vs. 1 situation), or three offenders and two defenders (3 vs. 3 situation). Participants were required to predict the direction of passing from the offender. Each film clip was terminated at 500ms (T1), 200ms (T2), 100ms (T3), or 0ms (T4) before, or 100ms (T5) after the ball had been passed. Skilled players showed high accuracy under T1, T2 and T3 conditions in the 3 vs. 3 situation than novice players. By using an Eyemark Record System, we tested the visual search strategy involved. The skilled players had lower search rates and longer fixation durations just before the ball was passed. These results suggest that, in comparison with novices, skilled soccer players adopt a more appropriate and effective visual search strategy, which has been acquired through experience in complex situations specific to soccer play.

    The oxygen consumption during physical exercise is necessarily dependent upon the load on the muscle and also on the mass of muscles at work. In the present study maximal work has been performed by legs and arms plus legs in pedaling bicycle ergometer.
    Thirteen healty male students were studied. Group A consisted of eight Judoists, aged 18-21 years. Mean maximal oxygen uptake and max O2 uptake/kg for this group were obtained 3.41/min and 44.7 ml/kg/min respectively in legs bicycle exercise. Group B consisted of five long distance runners, aged 19 years, with mean max. O2-uptake of 3.31/min and max. O2-uptake/kg of 57.2 ml/kg/min.
    In arms plus legs bicycle exercise, max. VO2 and max. VO2/kg were an average value of 3.81/min and 49.8 ml/kg/min respectively for group A. For group B max. VO2 and max. VO2/kg averaged 3.61/min and 62.6 ml/kg/min respectively.
    Group A 12% significantly higher values for max. VO2 was attained in arms plus legs cycling (P<0.01), but group B 9% higher max. VO2 when arms plus legs cycling than when legs cycling was actually not a regular finding in the group. Max. VO2/kg in legs cycling was an average 9-11% lower than that on arms plus legs cycling. The differences were statistically significant for group A and group B.
    Only in group A was max. VO2 a little higher than in group B for legs cycling, but the differences was not statistically significant. Max. VO2/kg was statistically significantly higher in arms plus legs cycling with both group. In group A max. heart rate, tidal volume and O2-pulse were higher in arms plus legs cycling. Then max. heart rate and tidal volume were significantly higher in group A than on group B.
