Everything about jumping and sprinting and how to improve your performance
HERE'S A QUESTION I GOT ASKED VIA MY YOUTUBE CHANNEL - REFERENCING DROP JUMPS AND THE VIDEO LINKED IN THIS POST. I have a question. If an athlete has a vertical of say 80cm what is the purpose of doing drop jump from a height substantially lower than its max since i can easily match those height by just jumping? But can the athlete with a counter-movement and very quickly with little knee bend? Drop jumps are primarily designed to improve rate of force development. Although the athlete may be able to jump 80m vertically quickly ... it's unlikely to be as quick as the time taken to take-off for the long jump 1100ms or from a lower height drop jump... drop jumps were designed to optimally develop that capacity by the former Soviets and they came up with designated jump heights for speed v strength (if I recall it was 70cm for speed and 1.10m for strength). Also, even with a good vertical jump a person might have trouble running from a 10 step approach and doing two hops and a jump, for example. The rate of force development and the single leg nature of the activity would likely be the issue. I hope my answer helps explain the rationale. Having a good vertical would provide a useful foundation for more specific long jump plyometric work, for example.
