I read an article this week on the development of lower limb stiffness in adolescence that got me thinking about how important this aspect of training is to adults as well. This study shows that during adolescence individuals develop stiffness in their joints that allows them to store elastic energy in their musculotendinous system when performing maximum countermovement jumps. That elastic energy storage is a very important aspect of power training, as it greatly effects an individuals power capabilities. The ability to jump high and run fast is somewhat dependent on the stretch shortening cycle (SSC) in your musculotendinous system. When an athlete performs a counter movement jump, there is a transfer of energy from the downward motion to their explosion upwards, and if the downward energy can be absorbed, stored, and used to explode upward the motion will be much more powerful, than with explosive power due to muscle alone. Think of it like a rubber band, the tighter a rubber band is, the more energy it will store (it has a stronger snap back). Likewise, the stiffness of a musculotendinous unit determines its potential to store elastic energy, to a point. Understanding where that point is, and how to train for it, can improve an athletes performance greatly, and to prevent injury. Knowing the point that an individual develops the necessary stiffness for elastic energy storage also gives important insight into training younger athletes. Any other thoughts?

Judith,

Terrific summary of thoughts in regards to the elastic energy utilization of the musculotendinous complex. It's astonishing to me how everyone feels as though they know and understand this scientific principle and how it should impact the application of the training methods that they may use. Unfortunately though, when we look at the trianing methods that they are incorporating, it does not reflext a thorough understanding of this very proven scientific fact in human movement science.

Again, terrific contribution.

How could this be implemented for a rehab technique (not necessarily right after it's torn since so many PTs fail to address certain aspects such as this when it comes to the rehab of an individual), say someone who has torn their ACL (years ago) and is looking to gain back some of their stiffness in an attempt to increase economy while being active in something as simple as a mile run.

Nice share ,. These results demonstrate that the neuromuscular function of adjusting active stiffness, storing elastic energy and optimizing the performance may decrease with age during CMJ.

And yeah, terrific contribution.

I guide the students that how they can pass the exams and how can they get the certification for the latest braindumps E20-393 knowledge this certification exam students click at exam or visit its certification its better for your bright future and will helpful to attain the IT certification
