Quadriceps Strain/Rupture - Phase 2

High-force eccentric contractions, excessive stretching, and muscle fatigue can cause acute quadriceps strain injuries. Common in sports like soccer, rugby, and football, these injuries result from sudden deceleration, violent contraction, or rapid deceleration of an overstretched muscle. This clinical grading system for muscle strains considers pain, loss of strength, and physical exam findings to guide treatment and rehabilitation. Grade I (mild) strains affect a limited number of muscle fibers. There is no decrease in strength, and the range of motion is fully active and passive. Grade II (moderate) strains involve nearly half of the torn muscle fibers. This causes acute pain and swelling and a slight decrease in muscle strength. The muscle tendon is almost ruptured. Grade III (severe) strains result in a complete muscle rupture. Severe swelling and pain and a complete loss of function are characteristic of this strain type. Longer rehabilitation is needed. The byrizz™ Quadriceps Strain/Rupture - 2.0 Overview;

• Symptom-free during all activities with normal strength, speed, and ROM. Improve neuromuscular control of the trunk, pelvis, and postural movements specific to the sport.

• In this program you will include higher velocity eccentric exercises with plyometric and sports-specific activities such as squat jumps, split jumps, bounding, depth jumps, single-leg bounding, backward skips, lateral hops, zigzag hops, plyometric box jumps, eccentric backward steps, eccentric lunge drops, eccentric forward pulls, and deadlift variations.
