东非长跑运动员取得惊人成功的原因包括独特的饮食习惯。本研究的目的是评估埃塞俄比亚优秀长跑运动员在高强度运动训练期间和重大比赛前的食物和常量营养素摄入量。对10名在高海拔（海拔约2400 m）生活和训练的埃塞俄比亚长跑运动员在比赛前7天的高强度训练期间的膳食摄入量进行了评估。还使用活动/培训日记评估培训。体重稳定（即，维持良好）（术前：56.7 ± 4.3 kg vs.术后：56.6 ± 4.2 kg，P = 0.54;平均值± SD）。饮食由13375 ± 1378 kJ组成，碳水化合物含量高（64.3 ± 2.6%，545 ± 49 g，9.7 ± 0.9 g/kg）。脂肪和蛋白质摄入量分别为23.3 ± 2.1%（83 ± 14 g）和12.4 ± 0.6%（99 ± 13 g，1.8 ± 0.2 g/kg）。液体摄入量主要包括水（1751 ± 583 mL），而在训练之前或训练期间没有摄入液体，训练后仅摄入少量液体。与之前在肯尼亚长跑运动员中进行的研究类似，这些埃塞俄比亚长跑运动员的饮食符合耐力运动员对常量营养素摄入量的大多数建议，但不符合液体摄入量。
Explanations for the phenomenal success of East African distance runners include unique dietary practices. The aim of the present study was to assess the food and macronutrient intake of elite Ethiopian distance runners during a period of high intensity exercise training at altitude and prior to major competition. The dietary intake of 10 highly-trained Ethiopian long distance runners, living and training at high altitude (approximately 2400 m above sea level) was assessed during a 7 day period of intense training prior to competition using the standard weighed intake method. Training was also assessed using an activity/training diary. Body mass was stable (i.e., was well maintained) over the assessment period (pre: 56.7 ± 4.3 kg vs. post: 56.6 ± 4.2 kg, P = 0.54; mean ± SD). The diet comprised of 13375 ± 1378 kJ and was high in carbohydrate (64.3 ± 2.6%, 545 ± 49 g, 9.7 ± 0.9 g/kg). Fat and protein intake was 23.3 ± 2.1% (83 ± 14 g) and 12.4 ± 0.6% (99 ± 13 g, 1.8 ± 0.2 g/kg), respectively. Fluid intake comprised mainly of water (1751 ± 583 mL), while no fluids were consumed before or during training with only modest amounts being consumed following training. Similar to previous studies in elite Kenyan distance runners, the diet of these elite Ethiopian distance runners met most recommendations of endurance athletes for macronutrient intake but not for fluid intake.
