The aim of this investigation was to study the physiological response to laboratory tests in elite and professional cyclists, and to relate it to the level at which riders compete and their specialization.
A total of 71 cyclists were divided into two groups, elite and professional, and were assessed for physical measurements, a maximal graded test and a 30 s all-out test, both performed on a cycle ergometer. The sample included 24 uphill riders (UR), 32 flat terrain riders (FTR), 11 all terrain riders (ATR) and 4 sprinters (SP).
Professional riders showed significantly higher gross mechanical efficiency (GME) than their elite counterparts (25.6+/-2.6 vs 24.4+/-2%), but otherwise no other physiological differences emerged from the comparison between these two groups. However, many differences exist as a function of rider specialization, especially between UR and FTR. Compared with FTR, UR showed a higher VO2max (78.2+/-5.5 vs 72.6+/-6.5 mL x min(-1) x kg(-1)) and a lower maximal aerobic power (438.5+/-40.8 vs 465.3+/-36.2 W). From the 30 s all-out test, SP presents the highest maximal power (P < 0.05) and maximal velocity (P < 0.05) compared with all the other groups.
The results for GME indicate a better efficiency for professional riders and suggest the importance of technical aspects related to movement pattern in cycling. The sensitivity of the maximal graded test and the 30 s all-out test did not allowed other differentiations between elite and professional cyclists.
本研究旨在探讨精英和职业自行车运动员对实验室测试的生理反应,并将其与运动员的比赛水平和专项进行关联。
71名自行车运动员被分为精英组和职业组,对他们进行身体测量、最大分级测试和30秒全力测试,所有测试均在自行车测功仪上进行。样本包括24名爬坡车手(UR)、32名平路车手(FTR)、11名全能车手(ATR)和4名冲刺车手(SP)。
职业车手的总机械效率(GME)显著高于精英车手(25.6±2.6 vs 24.4±2%),但两组之间的其他生理差异未显现。然而,根据车手专项存在许多差异,尤其是UR和FTR之间。与FTR相比,UR的最大摄氧量更高(78.2±5.5 vs 72.6±6.5 mL·min⁻¹·kg⁻¹),最大有氧功率更低(438.5±40.8 vs 465.3±36.2 W)。在30秒全力测试中,与所有其他组相比,SP的最大功率(P < 0.05)和最大速度(P < 0.05)最高。
GME的结果表明职业车手效率更高,并提示了自行车运动中与运动模式相关技术方面的重要性。最大分级测试和30秒全力测试的敏感性未显示精英和职业自行车运动员之间的其他差异。
