abstract
最近スポーツ外傷の予防効果に加えて,マウスガードの筋力発揮増強効果について関心が高まってきている.本研究では市販マウスガード(FMG)とカスタムメイドのマウスガード(CMG)の2タイプのマウスガードを用いて,マウスガードが握力,背筋力,等速性膝関節伸展筋力,等速性膝関節屈曲筋力,最大ペダリングパワーに及ぼす効果について検討した.結果は次の通りである.1.FMG およびCMG のいずれのマウスガードにも握力,背筋力に対する筋力増強の効果はみられなかった.2.CMG には等速性膝関節伸展筋力に対して有意な増強効果が認められた.しかしFMG およびCMG のいずれのマウスガードにも等速性膝関節屈曲筋力に及ぼす効果は認められなかった.3.CMG には最大ペダリングパワーに対する有意な増強効果が認められたが,FMG には認められなかった.4.以上の結果から,CMG にはゆっくりした速度の等速性運動において筋力発揮に効果のあることが示唆された.
abstract
As well as for their protective effect against sports injuries, interest is increasing in the value of mouth-guards for augmenting muscle strength. In this study the influence of two types of mouth-guards -commercial mouth-guards (FMG) and custom-made mouth-guards (CMG) - on grip power, back strength,peak torque in isokinetic knee extension, peak torque in isokinetic knee flexion and peak pedaling powerin rugby players are examined. The results are as follows. 1. No augmentation effect for grip power or back strength were noted in either of FMG and CMG. 2. A significant augmentation effect for peak torque in isokinetic knee extension was observed in CMG.However, neither FMG and CMG showed any affect on peak torque in isokinetic knee flexion. 3. A maximal pedaling power augmentation effect was noted in CMG but not in FMG.4. From the above-mentioned results, it was concluded that CMG had an augmentation effect on themuscle strength displayed in slow speed isokinetic exercises.
