It seems the squat jump he achieved more height by 4-6cm than the counter. In studies the countermovement has been shown to produce more jump height. But there is a slight adjustment head to spine alignment as the counter slightly follows a more definite curve than the squat. Interesting.
CMJ is a full movement and sometimes incorporates the arm movements, the squat jump has no arm movement (arm movement affects jump height, rotation and all those physics loool) as well as a pause while squatting to release any elastic/potential energy stored within the muscle fibres, tendons and ligaments.
No. The CMJ benefits from the rapid stretch on the elastic tissue components and perhaps neuromuscular potentiation. It is analogous to pitching which has virtually nothing to do with the strength of the muscles.
so the difference between the two is the angle at the knee? the angle is bigger for the countermovement jump while the angle is smaller for the squat jump, right?
The difference is the elastic energy stored in the muscle when doing a quick change of direction in force, which you do in Countermovement jump (CMJ). With Squat Jump (SJ) you take away that elastic stored energy by holding a static position before jumping, so the movement is only consentric. In this example, the squat jump is invalid, because the athlete dips abit down before jumping, thus using the benefits of CMJ.

If you look closely, he drops abit in the Squat jump, so the attempt is invalid, since he uses a bit of the benefits that CMJ gives.
OK, I give up. What is the difference?
Look at AudreDBAers answer

What exactly was the objective of this demo???
Hello! In this avaliable process jumps, how can I measure using a schedule (or chart) results? Like whith this video guy: Are the jumps good or not?
During the CMJ, is the length of time increased that the feet have to push into the ground during the upwards phase of this jump??

Athlete should spend more time at the bottom of the squat to fully dissipate any SSC effect
Tutorial to edit, please
both jumps look the same

@@Blackfeet because you can see it
@@AudreDBAer thank you so much ! i really needed this
@@AudreDBAer but the athlete doesnt use the arms in both of the video sir?
@@AudreDBAer do you know which system this is?
Amazing bro

GREAT THANKS FOR VİDEO

Não vejo diferença nenhuma nisso
Williams Lisa Clark Shirley Williams David
not a good Video because there are both CMJ!!!
Esta mal echa la prueba
