Fatigability is the tendency to become tired or exhausted easily. It's not just feeling a bit weary after a workout; it's a more pronounced and quicker onset of fatigue. Someone with high fatigability might struggle to maintain energy levels throughout the day. This can be due to physical or mental factors. Imagine trying to run a marathon with a sprained ankle – your fatigability would be through the roof. It is the measure of how easily someone (or something) gets tired.
