Exercise Intensity and Muscle Fiber Type Phenotype

The exercise intensity between VT2 and VO2 max is considered severe, leading to the shift into VO2 max eventually. Performance in this range is often linked to individual muscle fiber type phenotype. Individuals with more fast twitch muscle fibers are advised to push hard and not linger in this range frequently, while those with slow twitch fibers may find it more comfortable to sustain high intensity. Recognizing one's or an athlete's muscle fiber type is suggested for optimal training approach.
