The present case study examined the relationship between 24 h ultramarathon performance and the "big three" strategies of training, nutrition, and pacing.
A 32-year-old male ultramarathon runner (body mass: 68.5 kg, height: 179 cm) participated in a 24 h ultramarathon race. Training status was quantified based on from a GPS sports watch. The nutritional status was evaluated during the week leading up to the race, and blood glucose level and heart rate were measured during the race.
His aim of the distance was 200 km, but the actual performance was 171.760 km. The blood glucose level was stable because of adequate CHO intake before (7.2 ± 0.8 g/kg/day) and during the race (48 g/h). The running speed decreased in the middle and later stages of the race despite adequate CHO intake and a lack of high intensity running in the early stage of the race. The longest training session before the race (80 km) had to be significantly shorter compared to the aim.
For optimal 24 h ultramarathon performance, the "big three" strategies of training, nutrition, and pacing are all important. However, the performance level estimated based on previous studies may be achievable even with insufficient training, as long as the nutritional and pacing strategies are appropriate.
本案例研究考察了24小时超级马拉松成绩与训练、营养和配速这“三大”策略之间的关系。
一名32岁的男性超级马拉松跑者（体重：68.5千克，身高：179厘米）参加了一场24小时超级马拉松比赛。训练状态通过一块GPS运动手表进行量化。在比赛前一周评估营养状况，并在比赛期间测量血糖水平和心率。
他的目标距离是200千米，但实际成绩是171.760千米。由于赛前（7.2±0.8克/千克/天）和比赛期间（48克/小时）摄入了充足的碳水化合物，血糖水平保持稳定。尽管比赛期间碳水化合物摄入充足且比赛早期没有进行高强度跑步，但在比赛中期和后期跑步速度还是下降了。与目标相比，赛前最长的训练课（80千米）不得不显著缩短。
对于24小时超级马拉松的最佳成绩而言，训练、营养和配速这“三大”策略都很重要。然而，只要营养和配速策略得当，即使训练不足，根据先前研究估计的成绩水平也可能实现。
