The main objective of my current research project is to investigate sex-based differences in diaphragmatic fatigue (DF) after a pressure-threshold loading protocol under normoxic, acute hypoxic and hyperoxic conditions. In addition, to verify if there is a correlation between the magnitude of diaphragmatic fatigue, work of breathing, and oxygen availability. It is well acknowledged that women have smaller airways relative to lung size compared to men; this predisposes women to greater mechanical constraints during respiratory high-demand activities (i.e.
