What is Endurance?</h3>
- An organism's capacity to exert itself and remain active for a prolonged period of time, as well as its capacity to resist, withstand, recover from, and have immunity to trauma, wounds, or exhaustion, are all examples of endurance (also related to sufferance, resilience, constitution, fortitude, and hardiness). Usually, it is employed in anaerobic or aerobic exercise.
- Depending on the type of activity, "long" can mean anything from minutes for high-intensity anaerobic exercise to hours or days for low-intensity aerobic exercise.
- Unless a person additionally engages in resistance training to offset this effect, training for endurance can impair the ability to exert endurance strength.
