中文摘要 |
為了有效提高訓練的效果,常以科學方法評定運動訓練的強度與負荷量,一般係以血液中的乳酸(lactic acid;LA)、肌酸激(creatine kinase;CK) 與尿液中的蛋白質作為訓練強度的評定指標,而以血尿素氮(blood urine nitrogen;BUN)及血紅素(hemoglobin;Hb)作為訓練負荷量的評定指標。這些生化評定指標,在不同專項及訓練型態時會有所差異,因此為各專項選手建立適合的評定指標並瞭解訓練對該生化值的影響,將有助於訓練的監控進而提昇訓練效果。本研究以十四名國立體育學院桌球專長的學生為對象,在持續六天的多球訓練 (每天600至1200顆球)前後均以毛細管由指尖採血,並於訓練後15分鐘收集尿液,以評定桌球多球訓練的強度與負荷量。血液樣本處理後測量LA、CK、BUN及Hb,尿液樣本則測量蛋白質。結果顯示:訓練後血液中的CK及LA會顯著上升,部分選手亦會有尿蛋白出現的情形,而此三項生化值的變化有一致的趨勢;然而,訓練後血液中的BUN與Hb的變化並不明顯。因此每天600至1200顆多球訓練對桌球選手而言,負荷量並不大,訓練強度則達中度以上;且同時測量桌球選手訓練前後的CK、LA及尿蛋白可作為評定訓練強度的指標。此外,由實驗期前後的肝腎功能指數可知,六天的多球訓練對選手短期的肝、腎功能並未出現不當的影響。 |
英文摘要 |
Lactic acid, creatine kinase of blood and urinary protein usually act as indicators of training intensity. Blood urine nitrogen and hemoglobin act as indicators of training load. The training intensity and training load of ball feeding in table tennis are unknown. The purpose of this study was to investigate the biochemical parameters of table tennis players. Subjects were fourteen college students and were trained by ball feeding (600 to 1200 balls/day) for 6 days. A fingertip blood sample was drawn before and after the training. Urine was taken after 15 min of training. The concentrations of hemoglobin, lactic acid, creatine kinase and blood urine nitrogen in blood as well as protein in urine were measured. The results showed that lactic acid and cteatine kinase of blood increased significantly (p< .05) after exercise. The values of lactic acid, creatine kinase and urinary protein changed consistently. The changes of blood urine nitrogen and hemoglobin were not so remarkably. The training intensity and load of this study for table tennis players was moderate and low, respectively. |
