本研究目的有二：一、探討高中優秀籃球運動選手不同位置（中鋒、前鋒、後衛）賽後恢復期之血乳酸峰值及其出現時間；二、探討高中男子籃球運動員不同位置在比賽場上使用籃球步法之差異情形。研究方法是以92學年度HBL高中籃球聯賽前四強之12名男性優秀選手為對象。在實際比賽後之1、3、5、7、9、12、15、30分鐘收集血乳酸值；同時賽後觀看紀錄影片進行比賽中之相關籃球步法紀錄及統計分析。以獨立樣本單因子變異數分析為統計方法，以α=.05為顯著水準。得到結果如下：一、賽後乳酸峰值為4.43±2.15mmol•L^(-1)出現點在賽後第一分鐘；二、站／走步法（低強度）之結果顯示順序為中鋒、前鋒、後衛，均有統計上之顯著差異；前後移動步法（中強度）中鋒顯著大於後衛及前鋒；前後奔跑步法（中強度）中鋒顯著低於後衛及前鋒；衝刺移動步法（高強度）後衛顯著高於前鋒；而前鋒又顯著高於中鋒；高滑步步法（高強度）後衛顯著大於中鋒。本研究顯示，由於賽後恢復期之乳酸值並不高，且峰值出現點在賽後第一分鐘，因此研判，乳酸峰值或許在比賽中就已經出現。此外，高中籃球選手再比賽時使用各種步法的頻率會因不同的位置而有明顯的差異。
The purposes of this study were as follow: first, to examine the peak value of blood lactate and appear time after game in senior high school basketball players (centre, forward, guard). Secondly, to investigate the differences of the basketball footwork were used by different position. The participants were 12 HBL elite high school male players. Exam the blood lactate value at 1、3、5、7、9、12、15、30 minutes after game immediately; and collected the data of basketball footwork records from the real time films. One-way ANOVA was the statistical method (α=.05). Results were as follows: First, the average blood lactate peak value was 4.43±2.15 mmol•L-1, and appear time was at the first minute after game. Second, the record of stand/walk footwork has shown that there was significant differences among there position; the record of backward/forward moving footwork has shown that there was significant differences between centre and guard the record of sprint footwork has shown that the centre was lower than the guard and the forward significantly the record of high-speed side shuffle footwork has shown that the guard was higher than the centre significantly. In conclusion, our results had shown that maybe the peak blood lactate value was onset during competition, therefore, the after game blood lactate data were not as high as lab test data. From another point of view, because the low intensity, moderate intensity and high intensity basketball footwork required basic endurance, speed and power that there were significant differences among different positions.
