游泳比赛后血乳酸变化的纵向观察

Longitudinal Research of Post-competition Blood Lactate Concentration

本文对不同距离比赛运动员成绩及血乳酸的纵向变化进行了研究。对运动员3年纵向研究表明，随着运动成绩的显著提高，运动员赛后血乳酸显著降低。运动员参加不同距离比赛的血乳酸对比表明，以200米、100米赛后血乳酸最高，400米次之，50米列居第三，800米、1500米赛后血乳酸值最低。在不同泳姿中，仰泳赛后血乳酸最高，蛙泳、蝶泳血乳酸最低。混合泳项目血乳酸较高。

The longitudinal comparisons for post - competition blood lactate concentration of 28 swimmers were performed in 5 competitions in 3 years.competition performance was enhanced gradually in 5 competition concomitantly with blood lactate's gradual concentration decrease. It was also compared in this paper that post - competition blood lactate concentration of different swimming distances and different swimming styles.
