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.
Legacy AthleticsExplosive athletes do not just produce force. They transfer it efficiently. That begins with movement quality.
Legacy AthleticsAround early adolescence, something happens. Athletes who once improved rapidly begin to stall. Vertical stops increasing. Speed plateaus. Injuries begin to surface. This is not random. It is developmental.
