WHAT YOU'LL LEARN
- How muscles generate explosive power
- The role of fast-twitch muscle fibers
- Why technique matters as much as strength
THE SCIENCE EXPLAINED
Jumping requires converting stored chemical energy (in muscles) into kinetic energy (movement). Your leg muscles contract rapidly, pushing against the ground. Newton's Third Law: the ground pushes back with equal force, launching you upward. The power equation is: Power = Force × Velocity. Athletes train both strength (force) and speed (velocity).
SPORT IN ACTION
NBA players like Zion Williamson can jump over 40 inches vertically. They use a technique called 'plyometrics' - quick, explosive movements that train fast-twitch muscle fibers. Watch how they bend their knees and swing their arms upward to generate more force.
TRY IT YOURSELF
Try jumping with your arms by your side, then jump while swinging your arms up. Notice the difference? Arm swing adds momentum and helps you jump 10-15% higher!
QUICK FACT
The world record vertical jump is 63.5 inches (161 cm) - that's like jumping over a refrigerator!
KEY IDEA TO REMEMBER
Jump height = explosive power from muscles + proper technique. Train both strength AND speed!
