Cycling is a time-consuming sport. Cyclists, as many other athletes, therefore, focus on training effectively. The hypothesis was tested that twelve weeks of supplementary maximal acceleration training caused more favourable changes in cycling performance indicators as compared to changes measured in comparable control cyclists.
Trained cyclists (= 24) participated. A control group and a group performing maximal acceleration training, as a supplement to their usual training, were formed. The maximal acceleration training consisted of series of ten repetitions of outdoor brief maximal accelerations, which were initiated from low speed and performed in a large gear ratio. The cyclists in the control group performed their usual training. Performance indicators, in form of peak power output in a 7-s maximal isokinetic sprint test, maximal aerobic power output in a graded test, and submaximal power output at a predetermined blood lactate concentration of 2.5 mmol L in a graded test were measured before and after the intervention.
Peak power output in the sprint test was increased (4.1% from before to after the intervention) to a larger extent (= 0.045) in the cyclists who had performed the maximal acceleration training than in the control cyclists (-2.8%). Changes in maximal aerobic power output and in submaximal power output at a blood lactate concentration of 2.5 mmol L were not significantly different between the groups (> 0.351).
The results indicated that the applied supplementary maximal acceleration training caused modest favourable changes of performance indicators, as compared to the changes measured in a group of comparable control cyclists.
骑自行车是一项耗时的运动。因此，与许多其他运动员一样，自行车运动员专注于进行有效的训练。本研究检验了这样一个假设：与对照组的同等自行车运动员相比，为期12周的补充性最大加速度训练会使自行车运动性能指标发生更有利的变化。
招募了24名训练有素的自行车运动员。将其分为一个对照组和一个进行最大加速度训练的组，后者将最大加速度训练作为其常规训练的补充。最大加速度训练包括一系列从低速开始、以大传动比进行的10次户外短暂最大加速度重复训练。对照组的自行车运动员进行常规训练。在干预前后测量性能指标，包括7秒最大等速冲刺测试中的峰值功率输出、分级测试中的最大有氧功率输出，以及分级测试中在预定血乳酸浓度为2.5 mmol L时的次最大功率输出。
进行了最大加速度训练的自行车运动员在冲刺测试中的峰值功率输出增加幅度更大（干预前后增加了4.1%）（P = 0.045），高于对照组自行车运动员（下降了2.8%）。两组之间在最大有氧功率输出和血乳酸浓度为2.5 mmol L时的次最大功率输出变化方面无显著差异（P>0.351）。
结果表明，与一组对照组的同等自行车运动员相比，所应用的补充性最大加速度训练使性能指标发生了适度的有利变化。
