  • 摘要:

    A strict technical model is needed to optimize technique training, but the high jump allows a wide range of technical variation, and thus technical models cannot be restrictive. This dilemma has been resolved by classifying the flop technique. However, it is currently uncertain how the target technique should be selected from those presented, and how the chosen technique should be taught. The purpose of this study was to obtain such fundamental knowledge of technique training in the high jump based on a case of successful skill correction in a male university athlete. An 18-year-old male high jumper had used a jumping form resembling the “speed power flop” (Watanabe, 2007) until skill correction was implemented. The author advised him to change the target technique to the latest type of “speed flop” (Watanabe, 2010a) because daily observation of his jumps had suggested that his “biological type” (Vittori, 1971) was suitable for this technique. Within a few months, the athlete mastered the basic form of this technique and his personal record improved from 2.06 m to 2.14 m. Although the selection made in this case finally proved to be reasonable, the athlete felt a sense of discomfort with the new technique when he succeeded in performing its basic form for the first time. He also insisted that he was unable to jump any higher with the new technique than with the original one. Thus, the author had difficulty in persuading the athlete to continue training with the new technique because, at that time, the decision to select this technique for him had not been justified by studies. This training process indicated that further research was required to develop a standard or a protocol for technique selection that is good enough to allow coaches not to be misled by athletes' statements of experiencing discomfort. A further significant observation of this study was that the skill correction was triggered by changing the type of arm swing during the take-off phase. It was reported previously that changing the take-off leg can be used as a method for technique re-learning without being influenced by a previous skill. However, changing the take-off leg may lead to a significant reduction in performance during the process of technique acquisition. This case implied that changing the type of arm swing may be used as a method of skill correction with considerably decreased risk of significant performance reduction.
