(1) 長距離選手は椎間板変性の発生頻度が非競技者よりも低いことが明らかになった．(2) ランニング習慣がない場合は8km/hのランニングが必ずしも腰椎椎間板に好影響であるとは限らず，ランニングフォームも椎間板変性に関係する可能性が示唆された．(3) 8km/hのランニング中の前後方向の加速度は腰椎の屈伸方向となるため，L4/L5椎間板のT2値に最も影響を与えた可能性があると考えられる It was found that the prevalence of lumbar intervertebral disc degeneration in long-distance runner was lower than that in non-athletes.If the subject has no habit of running, running at 8km/h is not necessarily lead in positive effect in lumbar intervertebral disc. Running form might be related lumbar intervertebral disc degeneration.The results of this study suggest that changes in the T2 times of the lumbar disc degeneration due to running at 8 km/h are correlated with acceleration, suggesting that anteroposterior loading may contribute to the important response of the lumbar disc degeneration.
