What did I do?

My PhD aimed to investigate the mechanisms underlying performance fatigability according to sex following a maximal intermittent fatiguing protocol (IFPmax) using a flywheel device. To address this, four specific objectives were formulated: (1) to evaluate sex differences in the effects of varying moment of inertia (MI) on the reliability of performance-related variables using a flywheel device,1 (2) to identify sex differences in performance decline during the IFPmax,2 (3) to examine changes in voluntary muscle activity,3 and (4) to assess electrically-evoked mechanical and electromyographical variables following the IFPmax.4

Why did I do it?

The biological sex of a cell can fundamentally influence physiological function and result in sex differences. Accordingly, performance fatigability may differ between male and female sexes during isometric and dynamic tasks, with relevant implications for training adaptations.5 Males tend to exhibit greater fatigability than females…
