目的：本研究主要在探討籃球運動模擬比賽前後血尿素氮及肌酸激酶的變化。方法：本研究是以20位年滿20歲之大專乙組男子籃球隊員為對象，實驗前依平衡處理原則將20名受試者分為實驗組10名及對照組10名。實驗組10名球員採隨機分成實力相當的兩隊，進行籃球模擬比賽。比賽的時間40分鐘，分為4節，每節10分鐘（第1節與第2節之間休息2分鐘；第2節與第3節之間休息5分鐘；第3節與第4節之間休息2分鐘）。並分別於比賽前及比賽後1、3、6、24及48小時進行靜脈採血。以重複量數單因子變異數分析來檢定不同組別在組內及組間不同時間BUN與CK的變化差異。結果：實驗組BUN在比賽後1、3、6小時顯著升高(p<.05)，其中又以比賽後6小時達到最高點，於比賽後24小時恢復接近至安靜值。CK則於比賽後1、3、6、24小時達顯著升高(p<.05)，其中又以比賽後6小時達到最高點，於比賽後48小時恢復接近至安靜值。對照組於實驗前後BUN、CK則無明顯變化。結論：籃球運動比賽對BUN的影響時間較短，對CK的影響則會持續至24小時。因此，在進行一場籃球運動模擬比賽訓練時，應有24小時的間隔時間以利代謝機能的恢復。

Purpose: This research study positions the focus primarily on investigating fluctuations in the serum urea nitrogen and creatine kinase prior to and after the basketball simulation game. Methodology: This research study took 20 members from the teams of the National Collegiate Basketball Class B, at the age of 20, as the research subject. Prior to the commencement of the experiment, in accordance with the principle of balanced operation, these 20 testees were divided into the Experiment Group and the Control Group, with 10 persons per group. 10 team members of the Experiment Group were randomly divided into two teams with equal playing skills for conducting the basketball simulation games. The time length of the game was set for 40 minutes and divided into 4 periods, with 10 minutes per period (2-minute intermission between Periods 1 and 2; 5-minute intermission between Periods 2 and 3; 2-minute intermission between Periods 3 and 4). Venous blood samples were collected respectively at the time intervals of 1 hour, 3 hours, 6 hours, 24 hours, and 48 hours prior to and after the game. The one-way ANOVA with repeated measures was adopted to examine the variations of BUN and CK among different teams within and in between the respective groups at various time intervals. Result: The Experiment Group BUN exhibited a significant increase at the time intervals of 1 hour, 3 hours, and 6 hours after the game (p<.05), especially with the peak reached at 6 hours after the game and the recovery to the pre-exercise level achieved 24 hours after the game. The CK Group exhibited a significant increase at the time intervals of 1 hour, 3 hours, 6 hours, and 24 hours after the game (p<.05), especially with the peak reached at 6 hours after the game and recovery to the pre-exercise level 48 hours after the game. For the Control Group, both BUN and CK exhibited no significant variations prior to and after the game. Conclusion: Basketball games exerted a shorter time effect on BUN, while sustaining the effect on CK for 24 hours. Therefore, a 24-hour time interval shall be suggested for facilitating the recovery of the metabolic functions when conducting the training for the basketball simulation game.
