本研究では,口頭による言語指示が,着地動作における股および膝関節の角度に影響をおよぼすか調査した。対象は,高校女子バスケットボール部員7名とし,関節角度は三次元動作解析装置により測定した。課題は,高さ30cmの台から両脚にて,まず任意により自由に着地し,次に「つま先と膝の方向をまっすぐするように着地してください」と指示し,再び着地した。その結果,股関節は,接地時と最大垂直床反力時に指示後が指示前より有意に外転した(p<0.05)。膝関節は,いずれの関節角度とも,言語指示による影響は認められなかった。膝関節の内外反角度を変化させるには1回の単純な言語指示では困難であることが示唆された。
The aim of this study is to investigate whether athletes can alter their knee kinematics during a drop landing task by following simple verbal instructions. This study included 7 high school female basketball players. The subjects performed a leg drop landing task using both legs, from a box situated at a height of 30 cm. Five sets of infrared video cameras attached to a 3-D analyzer system were used to capture the hip and knee angles during the landing tasks. First, the subjects landed naturally, with no verbal instructions (natural-landing). They were then instructed to land with their lower extremities in a neutral position in the sagittal plane; after receiving these instructions, they performed the landing task a second time (verbal-landing). At initial contact and at a peak vertical ground reaction force, the hip abduction angle during verbal-landing was significantly greater than that during natural-landing. The knee angles were not significantly different between the 2 types of landing. This study suggested that a single intervention with verbal instructions did not significantly decrease the knee valgus during leg landing using both legs.
