The aim of this study was to evaluate the demands of riding a "Grand Tour" by monitoring both heart rate and power output in 15 professional cyclists. SRM power output profiles (SRM Trainingsystem, Jülich, Germany) were collected during 148 mass start stages during the 2005 Tour de France and analyzed to establish average power, heart rate (HR) and cadence produced in different terrain categories (flat [FLT]; semi-mountainous [SMT]; mountainous [MT]). The maximal mean power (MMP) for progressively longer durations was quantified. Average HR was similar between FLT (133 +/- 10 bpm) and SMT (134 +/- 8 bpm) but higher during MT (140 +/- 3 bpm). Average power output revealed a similar trend (FLT 218 +/- 21 W [3.1 +/- 0.3 W/kg], SMT 228 +/- 22 W [3.3 +/- 0.3 W/kg], and MT 234 +/- 13 W [3.3 +/- 0.2 W/kg]). Cadence during MT was approximately 6 - 7 rpm lower (81 +/- 15 rpm) compared to FLT or SMT. During MT stages, the MMP for 1800 sec. was highest (394 W vs. 342 W) but the MMP 15 was lower (836 W vs. 895 W) compared to FLT. The data document comprehensively the power output demands during the Tour de France.
本研究旨在通过监测15名职业自行车运动员的心率和功率输出，评估“大环赛”骑行的需求。在2005年环法自行车赛的148个集体出发赛段中收集了SRM功率输出数据（SRM训练系统，德国于利希），并进行分析，以确定在不同地形类别（平地[FLT]；半山区[SMT]；山区[MT]）中产生的平均功率、心率（HR）和踏频。对持续时间逐渐延长的最大平均功率（MMP）进行了量化。FLT（133±10次/分钟）和SMT（134±8次/分钟）期间的平均心率相似，但MT期间（140±3次/分钟）更高。平均功率输出呈现出类似趋势（FLT为218±21瓦[3.1±0.3瓦/千克]，SMT为228±22瓦[3.3±0.3瓦/千克]，MT为234±13瓦[3.3±0.2瓦/千克]）。与FLT或SMT相比，MT期间的踏频大约低6 - 7转/分钟（81±15转/分钟）。在MT赛段，1800秒的MMP最高（394瓦对342瓦），但与FLT相比，15秒的MMP较低（836瓦对895瓦）。这些数据全面记录了环法自行车赛期间的功率输出需求。
