| 中文摘要: |
| 为探究静水皮艇200 m能量供应特征，文章选取了29名青少年皮艇运动员在测功仪上进行 200 m比赛的模拟（40 s）。通过采集受试者气体代谢和血乳酸数据，并按Beneke等人提出的计算方法进行能量代谢的计算。结果表明，静水皮艇 200 m三大供能系统的供能比例分别为39.4%（无氧无乳酸）、28.8%（无氧乳酸）和31.8%（有氧）。静水皮艇 200 m前10 s能量供应主要来自无氧无乳酸系统，第10~20 s（或30 s）能量供应主要来自无氧乳酸系统，有氧供能对于最后10~20 s的运动能力有重要意义。我国目前对静水皮艇200 m的认识低估了有氧供能的重要性。静水皮艇200 m能量代谢的时序特征可以作为制定训练计划和评价运动能力的重要生物学基础。 |
| 英文摘要: |
| In order to study the energy supply characteristics of 200m kayak sprint, 29 junior kayakers were selected for a 40s simulation 200m race on ergometers. Parameters of the subjects’ gas metabolism and blood lactic acid were collected and calculated for energy metabolism with the calculation method introduced by Beneke et al. The result demonstrates that the energy supply proportion of the three systems of 200m kayak sprint is 39.4% (anaerobic alactic acid), 28.8% (anaerobic lactic acid) and 31.8% (aerobic) respectively. The energy supply of 200m kayak sprint in the first 10s is from anaerobic alactic system. The energy supply in 10-20s (or 30s) comes from anaerobic lactic acid system. And aerobic energy supply plays an important role in the last 10-20s. At present, the contribution of aerobic energy supply is underestimated in China. The timing characteristics of the energy metabolism in 200m kayak sprint can be regarded as an important biological basis for working out training program and evaluating performance ability. |
