不同練習方法對排球接發球之影響

Abstract

問題背景：接發球是排球基礎且重要的技術，有良好的接發球技術，可以增加第一波攻擊的優勢，進而增加比賽獲勝的機率。然而，要有良好的接發球要先有好的傳球能力。目前，常見的練習方法為對空傳球或是低手對牆傳球，這些方法真的對實際接發球會有效果嗎？目的：探討低手對牆傳球練習與場地練習對排球接發球表現之影響。方法：16名實驗參與者在進行低手對牆測驗與場地接發球測驗之前測後，隨機分為低手對牆傳球組與場地接發球組，進行每週兩次，一次20分鐘，共四週的練習。低手對牆傳球組在規定的範圍內進行低手對牆傳球練習，場地接發球組在場地六號位上進行接發球練習。四週練習後進行後測。低手對牆傳球測驗的得分與場地接發球測驗的得分分別以混合二因子變異數分析(2組別X前後測)考驗不同練習方法學習效果的差異。結果:低手對牆傳球組與場地接發球組在各自的練習上皆有進步，但兩組之間互相沒有遷移。結論:練習 那種技能動作只對那種動作有效果。Background: Reception was a basic and important skill in volleyball. With great volleyball reception skill, the effect of complexⅠmay be improved and increased the probability to win the game. However, if players want to have a great reception they must have a good passing ability first. Up to now, the most popular practice methods were passes in the air or passes onto the wall. Were these practice methods actually effective when applying the skill of reception in the actual game ? Purpose: To examine the influence of two underhand pass practice. methods: pass onto the wall and field reception. Method: Sixteen participants were randomly assigned to one of the two practice groups after the pre-tests, followed by four weeks of practice with the frequency of two sessions a week, twenty minutes a session. The wall group practiced within a predetermined range and field group practiced on the number six position. All participants performed the post-tests after four weeks practice. The mixed design two way ANOVA was used for the data analysis. Result: The two groups improved the performance of the skill that they practiced, but did not transfer to the other condition. Conclusion: The effect of skill learning only depends on what you practiced.
