The Amazing Mechanics of Running and Jumping

Spring System: Your tendons act like elastic springs during running.
Air Time: Jumping adds a brief period where the body is completely airborne.
Force Burst: Running involves impact forces up to three times body weight.
Quick Fire: Calf muscles contract rapidly to produce high-speed motion.
Propulsion Arc: Body angles determine jump height and running efficiency.
Stride Shift: Faster running increases stride frequency more than stride length.
Hip Power: Strong hips drive both running acceleration and jump lift.
Gravity Game: Jump height depends on how fast you can push against gravity.
Ground Contact: Reducing ground-time improves running speed.
Energy Rebound: Elastic recoil saves energy during repeated strides.
