tendons, not muscle...

are the key to elastic energy storage which evolved allowing humans to kill effectively from a distance.

Read these and see if you didn't already know this as principles from TCMA.

"Elastic energy is potential mechanical energy that animals store in tendons, ligaments, and muscles. When these structures are stretched they elongate like an elastic band. When the forces pulling on these elements are then reduced, they return to their original shape, releasing the energy that was used to stretch them. This elastic energy can be used to power forceful movements (such as a frog’s jump) or to make movement more energetically efficient (such as the human Achilles tendon during running)."

"We further found that three key anatomical changes that occurred during human evolution made this novel energy storage mechanism possible: expansion of the waist, lowering of the shoulders, and low humeral torsion. The expansion of the waist allows the torso to rotate independently from the hips. This torso rotation generates large forces needed to stretch the elastic tendons and ligaments in the shoulder. The lowering of the shoulder changes the orientation of many shoulder muscles, including the pectoralis major (the large chest muscle), which is crucial to storing energy. Finally, we found that low humeral torsion (the twisting of the upper arm bone) allows us to store more energy and thus making Pi Qua Tang Lang so effective."

Ok, that last part about Praying mantis was just editorializing.

But how often are we pointing out these details when trying to correct biomechanics in our students?

tendon strength is gained by lifting heavy weights

As if you can have one without the other...

Tendon is muscle head. It's the tighter fibrous stuff that attaches the muscle to the bone. As SR said, you can't have one without the other.

Regard the body as a unified machine. It all needs to be developed. It won't develop fully if you focus only on one thing about it.

Yeah, I know.

Just giving people a chance to argue.

After the arguing is done, then you all can post pics of scantily clad brunettes.

"They noted that around half the throwing power comes not from muscles, but from ligaments and tendons around the shoulder, which stretch, store and then quickly release elastic energy."

The principles of elastic energy storage and release apply to any most movements.

What you CANNOT do is to train only a muscle, tendon, or ligament separately. Each of these is inexorably linked to the other in that the muscle produces the force that transfers energy to the tendon attaching it to the bone which transfers energy to the ligament that connects the bones.

"[...] rapid, sequential activation of many muscles, starting in the legs and progressing through the hips, torso, shoulder, elbow and wrist. Torques generated at each joint accelerate segmental masses, creating rapid angular movements that accumulate kinetic energy [...]"

"[...] the tall, mobile waists of humans decouple the hips and thorax, permitting more torso rotation, in turn enabling high torque production over a large range of motion (ROM) [...]"

A lot of TCMA training focuses on optimizing the above two elements.
