Abstract

A 91-year-old female set the W90+ world record in the 200m sprint in 2024. We characterized her neuromuscular function, fatigability, denervation markers, and single-fiber contractile properties, and, where possible, compared these outcomes to published reference data. Knee extensor muscle architecture, force, power, fatigability, and motor unit (MU) behavior were assessed

Research summary

The paper claims to characterize the neuromuscular profile of a 91-year-old world-record sprinter. This research is relevant as it explores the physiological aspects of aging and high-level athletic performance, potentially offering insights into maintaining muscle function and performance in advanced age.
