Definitions:

Fast Twitch Fibers

Muscle fibers characterized by their quick contraction and high power output, often engaged in explosive movements.

Anaerobic Activity

Physical activity that occurs in the absence of enough oxygen for the complete burning of sugars, resulting in lactic acid production.

Slow-twitch Fibers

Muscle fibers characterized by their ability to sustain long endurance activities; they fatigue slower compared to fast-twitch fibers and are rich in mitochondria.

Muscular Strength

The maximal force that a muscle or group of muscles can exert against resistance in a single effort.
