Plyometrics: Don t be a QUAD DOMINANT JUMPER

In this video I talk about the pitfalls of being a quad dominant jumper. This means that the jumper wants to load disproportionally thought their front thighs when jumping. This can make for slower ground contacts and reactive forces and reduce the contribution the hips and the ankle joints make to sprinting and jumping, for example. Now, it does not mean that the quad dominant jumper will be a poor jumper, in fact they may well be very good jumpers and in particular triple jumpers (from my experience). However, as indicated they may lack sprinting speed due to not having a quickfire ground contact. Their coupling between the eccentric muscle stretch and the concentric muscle shortening plyometric actions may be longer. So, they need a little more time to express force. I have also found that these types of jumpers are less able to rotate their legs quickly and they may also sit when they are running. This is because they firstly, often have underdeveloped hip flexors and secondly, they are not runn br, br,
