Legacy AthleticsThe True Sources Knee overload often results from: • Weak hip stabilization • Poor ankle mobility • Improper landing mechanics • Rapid growth without coordination adaptation The knee absorbs force that should have been distributed.
Legacy AthleticsCommon Red Flags • Knee valgus during squat • Asymmetrical hip shift • Shoulder elevation during pressing • Uneven gait pattern • Limited thoracic rotation These issues may not hurt initially. But they limit ceiling and increase risk.
Legacy AthleticsWhy the Foot Matters The foot must: • Absorb force • Stabilize quickly • Transfer energy upward If the arch collapses or ankle mobility is restricted, force leaks occur. That leak limits jump height.
Legacy AthleticsWhat Is Elastic Power? Elastic power refers to the body’s ability to: • Store energy during loading • Release it rapidly during extension • Minimize ground contact time
Legacy AthleticsHorizontal Power vs. Vertical Power The broad jump measures horizontal force production. The vertical jump measures vertical force expression.
Legacy AthleticsHeavy squats build slow strength. Vertical jump requires: • Rapid force development • Coordinated hip extension • Efficient triple extension sequencing Without sequencing, force dissipates.
