Understanding Decoupling in Marathon Performance
Decoupling refers to the relationship between internal and external workloads during endurance activities, particularly running. This phenomenon was explored in a study that analyzed data from a large cohort of marathon runners, revealing that elite athletes maintain a lower decoupling ratio, signaling better efficiency in managing their heart rate relative to their pace. Runners completing marathons in faster times do so while maintaining a higher percentage of their critical speed, whereas those taking longer tend to exhibit greater decoupling. This suggests that not only is critical speed significant for performance, but the rate at which an athlete's internal workload increases relative to their external efforts plays a crucial role in marathon outcomes.
