Women exhibit an attenuated exercise pressor reflex (EPR) when compared to men. The influence of sex-specific mechanisms related to the EPR and performance fatigability remain to be fully elucidated. The purpose was to determine the impact of oxygenation and metabolic efficiency on sex-specific performance fatigability and increases in mean arterial pressure (MAP) resulting from a fatiguing isometric handgrip (IHG).

- - The study explored how muscle activation and motor unit number estimation (MUNE) affect the rate of torque development (RTD) during rapid muscle contractions in younger (average age 22) and older men (average age 74).
- - Researchers recorded early phase RTD and muscle excitation using surface electromyography from the quadriceps, finding that muscle activation significantly influenced RTD, especially in older men.
- - The results indicated that older adults rely more on muscle activation at the start of contractions than younger adults, while MUNE did not significantly impact RTD for either age group.
