[背景了解]
　　文章取自于2003年9月的閱讀真題，是關(guān)于運(yùn)動(dòng)員訓(xùn)練與休息的文章，選段有些長，希望耐心看下，自己先猜下劃線部分單詞的意思吧
　　[文章部分]
　　If sufficient rest is not included in a training program, imbalance between excess training and inadequate rest will occur, and performance will decline. The “overtraining syndrome(綜合癥)” is the name given to the collection of emotional, behavioral, and physical symptoms due to overtraining that has persisted for weeks to months. It is marked by cumulative exhaustion that persists even after recovery periods.
