Evidence and use
The term names a movement, not a diagnosis or complete exercise prescription. Range or strength alone does not guarantee running speed, injury prevention or HYROX® performance.
OpenStax · Types of body movements
Include plyometric work such as pogos and ankle hops (2-3 sets of 15-20 contacts) to develop the reactive plantarflexion strength needed for efficient running mechanics.[^2][^1] Ensure adequate calf stretching post-training to maintain dorsiflexion range. Use Repz to track whether your running pace drops in later segments, which often correlates with calf fatigue and reduced plantarflexion power.
