| （华南师范大学 体育科学学院，广东 广州 510006） 摘 要：通过测试4周强化有氧训练(LT强度)前后广东省女子自行车运动员的VO2max、LT、VT、HR、VE等指标变化，以观察有氧耐力的变化。结果显示：1)VO2max、VT均无明显变化(P>0.05)；2)训练前后VO2max、LT、VT与心率均显著相关(P<0.05)。3)VT、LT时与心率显著相关(-0.592，P<0.05)，回归方程为：Y(LT时心率)=218.120－0.343 X(VT心率)。结论：1)为期4周的有氧耐力强化训练(LT强度)并不能够明显提高女子自行车运动员VO2max、VT的水平；2)采用心率控制训练强度是科学合理的；3)实验室测试VT心率在实际训练中需要校正后再用。 |

Conclusions: 1)4-week aerobic stamina intensified training (LT strength) failed to significantly improve the levels of VO2max and VT of the female cyclists; 2)controlling training intensity by means of HR is scientific and rational; 3)HR at VT measured in a laboratory needs to be calibrated before it is used in ac-tual training. |
