The present study investigated to what extent more high aerobic intensity interval training (HAIT) and reduced training volume would influence maximal oxygen uptake (VO2max) and time trial (TT) performance in an elite national cyclist in the preseason period. The cyclist was tested for VO2max, cycling economy (C(c)), and TT performance on an ergometer cycle during 1 year. Training was continuously logged using heart rate monitor during the entire period. Total monthly training volume was reduced in the 2011 preseason compared with the 2010 preseason, and 2 HAIT blocks (14 sessions in 9 days and 15 sessions in 10 days) were performed as running. Between the HAIT blocks, 3 HAIT sessions per week were performed as cycling. From November 2010 to February 2011, the cyclist reduced total average monthly training volume by 18% and cycling training volume by 60%. The amount of training at 90-95% HRpeak increased by 41%. VO2max increased by 10.3% on ergometer cycle. TT performance improved by 14.9%. C(c) did not change. In conclusion, preseason reduced total training volume but increased amount of HAIT improved VO2max and TT performance without any changes in C(c). These improvements on cycling appeared despite that the HAIT blocks were performed as running. Reduced training time, and training transfer from running into improved cycling form, may be beneficial for cyclists living in cold climate areas.
本研究旨在探讨在赛前阶段，更多的高有氧强度间歇训练（HAIT）和减少训练量将在多大程度上影响精英国家自行车运动员的最大摄氧量（VO2max）和计时赛（TT）表现。在一年的时间里，自行车运动员在测功计上进行了 VO2max、骑行经济性（C(c)）和 TT 性能测试。在整个期间，使用心率监测器连续记录训练情况。与 2010 年赛前相比，2011 年赛前的总月训练量减少，进行了 2 个 HAIT 训练块（9 天内进行 14 次训练和 10 天内进行 15 次训练），形式为跑步。在 HAIT 训练块之间，每周进行 3 次 HAIT 训练，形式为骑行。从 2010 年 11 月到 2011 年 2 月，自行车运动员减少了总平均每月训练量的 18%和骑行训练量的 60%。90-95%HRpeak 的训练量增加了 41%。测功计上的 VO2max 增加了 10.3%。TT 性能提高了 14.9%。C(c)没有变化。总之，赛前减少了总训练量，但增加了 HAIT 的量，提高了 VO2max 和 TT 表现，而 C(c)没有变化。尽管 HAIT 训练块是跑步形式，但这些在自行车上的改善还是出现了。减少训练时间，以及从跑步到提高的自行车形式的训练转移，可能对生活在寒冷气候地区的自行车运动员有益。
