A case report of coaching for resolving “under-rotation” during second-turn phase in the discus throw

Abstract

    This study reports a coaching case of a male athlete (abbreviated to “athlete A” after this) who had a problem that left foot lands on the “under-rotation” position during second-turn phase in the discus throw. Since athlete A is the author, this study shows processes and reflections of self-coaching. First, one of the factors which caused “underrotation” was that athlete A was too self-conscious about quick touchdown of left foot during second-turn phase. Then, “turn drill without landing left foot” and “half-turn throw” were adopted as technical training to resolve “under-rotation”. Although the number of trials which left foot lands on the “under-rotation” position reduced to a certain degree after both training, the problem had not been resolved completely. However, coaching processes showed in this study can contribute accumulation of a case study to construct general theory about resolving “under-rotation” in the discus throw.
