| 目的：研究和揭示小轮车泥地竞速比赛的有氧代谢和无氧代谢特征。方法：对3名广东省重点运动员在赛前模拟赛、全国冠军赛和锦标赛赛时进行全程心率和赛后血乳酸进行值测试和分析。结果：（1）在模拟赛、全国冠军赛和全国锦标赛赛时运动员每轮比赛的最高心率都达到个人峰值心率（HRpeak）的90%以上，平均心率达到88% HRpeak以上；（2）每轮比赛赛后间歇期平均心率处在67%~70%HRpeak的中等强度心率范围，且整体呈上升趋势；（3）全国正式比赛赛后血乳酸水平明显高于模拟赛，达到最高乳酸训练区（血乳酸值大于15 mmol/L）的强度。结论：小轮车泥地竞速项目不仅对运动员最大无氧代谢能力提出了极高要求，同时要求运动员具备优秀的有氧代谢能力。 |

| Objective: To study and reveal the characteristics of aerobic and anaerobic metabolism in BMX racing. Method: The full-time heart rate and blood lactic acid value after each round of 3 elite athletes of Guangdong Province were measured and analyzed during the pre-competition simulation race and the national championships. Result: (1) The maximum heart rate of the subjects in each round reached more than 90% of the individual peak heart rate (HRpeak), and the average heart rate reached more than 88% HRpeak. (2)The average heart rate during the interval period after each round was in the range of moderate heart rate of 67%-70%HRpeak, and the overall trend was upward. (3)The value of blood lactic acid (BLA) after the national championships was obviously higher than that of the simulation competition, reaching the highest training area lactate (BLA> 15 mmol/L). Conclusion: BMX racing not only requires the maximum anaerobic metabolic ability of the athletes, but also requires excellent aerobic metabolic capacity. |
