One of the major concerns for professional drivers is fatigue. Many studies evaluated specific fatigue countermeasures, in many cases comparing the efficiency of each method separately. The present study evaluated the effectiveness of rest areas combined with consumption of energy drinks on professional truck drivers during a prolonged simulated drive. Fifteen professional truck drivers participated in three experimental sessions: control-drivers were asked to drink 500 ml of a placebo drink prior to the beginning of the drive. Energy drink-drivers were asked to drink 500 ml of an energy drink containing 160 mg of caffeine prior to the beginning of the drive, and an Energy drink+Rest session--where the drivers were asked to drink 500 ml of an energy drink prior to driving, and rest for 10 min at a designated rest area zone 100 min into the drive. For all sessions, driving duration was approximately 150 min and consisted of driving on a monotonous, two-way rural road. In addition to driving performance measures, subjective measures, and heart rate variability were obtained. Results indicated that consumption of an energy drink (in both sessions) facilitated lower lane position deviations and reduced steering wheel deviations during the first 80-100 min of the drive relative to the control sessions. Resting after 100 min of driving, in addition to the energy drink that was consumed before the drive, enabled the drivers to maintain these abilities throughout the remainder of the driving session. Practical applications: Practical applications arising from the results of this research may give indication on the possible added value of combining fatigue counter measures methods during a prolonged drive and the importance of the timing of the use for each method.
职业驾驶员主要关注的问题之一是疲劳。许多研究评估了特定的疲劳对策，在许多情况下，分别比较了每种方法的效率。本研究评估了在长时间模拟驾驶过程中，休息区与能量饮料的联合使用对专业卡车司机的效果。15 名专业卡车司机参加了三个实验：对照司机在开始驾驶前被要求喝 500 毫升安慰剂饮料。能量饮料司机在开始驾驶前被要求喝 500 毫升含有 160 毫克咖啡因的能量饮料，而能量饮料+休息区司机在驾驶前被要求喝 500 毫升能量饮料，并在驾驶 100 分钟后在指定的休息区休息 10 分钟。对于所有的实验，驾驶时间大约为 150 分钟，驾驶在单调的双向农村道路上进行。除了驾驶性能测量外，还获得了主观测量和心率变异性。结果表明，与对照实验相比，在驾驶的前 80-100 分钟内，饮用能量饮料（在两个实验中）可以减少车道位置偏差和转向轮偏差。在驾驶 100 分钟后休息，除了在驾驶前饮用的能量饮料外，还可以使驾驶员在整个驾驶过程中保持这些能力。实际应用：本研究结果可能表明，在长时间驾驶过程中结合疲劳对策方法的可能附加价值，以及每种方法的使用时机的重要性，这可能会带来实际应用。
