I recall through many years in the skiing industry how many guys and gals spend 2 to 4 years to become a PSIA full cert., or obtain their gold pin. The same thing with the US Ski Coach Asso,
both make a ton of money from the union and the many instructors and coaches!
It is also very funny how many just get their gold pins and make bold claims that they know everything about the sport? The same thing occurs when someone just get their degree, they are going to set the woods on fire until the their first rain storm washes that out.
Fitting is very much the same way, in only the last few years have we seen the many fit"school" system, all claiming they have the gold pin and they know? Now think of the guy who wants to buy the info, he wants someone to sell him the gold pin without earning it? Happens all the time, people buy into a fit system, only to not know how to use it.
To hold a position while skiing is crazy and when you are on the steeps, skiing pretty can get you killed. I have the gold pins learn to play on their playground and get hauled off where real effort is needed. To camp out up on the saddle and look pretty looks cool, but....
There is always someone who wants to get into the game, rather smells the money from marketing hype. For them, its all about moving aftermarket products and profit!
There are bold claims written off as marketing hype, better many are a very compelling story. So it becomes difficult to judge how things make a difference on a given bike. Now we have (You Tube) and many making claims how the hip, patella, ankle and pedal should work.
Read this:
To use video in order to find angles or to track the joints for (compression, shearing, tension) is not what you think. Many of the systems don't use Newton's laws of motion. Forces are constantly changing as a result of many factors. There are many rotary components.
The video is not much different than your eye, yes you can stop it at a given time stamp, but if you don't know what to look at, its mostly sizzle.
Force has been used frequently in connection with dynamics and Newton's laws of motion. Strength is more difficult to define because the force or tension muscles create is not directly measurable, muscle tension acts via the skeletal leverage system. It can only be measured in terms of force, torque, or work produced. It very ambiguous, open to more than one interpretation; having a double meaning, very unclear or inexact.

Our CAD has stood the test of time and it is more exacting, and we get results. That is why we use it, it allows the user to improve and break down the forces. The idea is not to waste muscle energy that don't contribute to any movement.
The principal muscles used in pedaling:
- the upper leg (quadriceps) sartorius, rectus femoris, vastus medialis, vastus lateralis.
- the back of the leg (hamstrings) semimembranosus, semitendinosus, biceps femoris
- gracilis
- tensor facia lata
- gluteus maximus
- popliteus
- the lower leg (back) gastrocnemius "medial, lateral", soleus
- the lower leg (front) tibialis anterior, peroneus
Muscular endurance and skill significantly contribute to your endurance. By increasing the efficiency and reducing the energy cost and the fatigue with a given task. Muscular endurance and cardiovascular-respiratory endurance are separate factors in any human performance. One doesn't have to accompany development of the other.
Endurance depends on the training and the O2 uptake and the transport mechanisms.
The ability of the heart to pump blood is seen as the most common limiting factor, but the heart is not the only important one.
Any method or device claiming more control for less effort in the development of strength are simply fraudulent. The brain sends a neural stimulation to the muscles for the the job you wish.
The same is true for the brain "cortex" to learn for going harder and get the ride over quicker. The longer you stay on the bike the harder it is. So get motivated and ride, you can recover later!
To attempt to get more flexibility, to go beyond the range of motion is said to add to one's performance? On the bike, its best to not place a joint beyond its range e.g. hip. Weather the exercise is resistive, assisting, or even passive in which many ride.
A passive or even a ballistic stretch (heel down) stretching can initiate your hard wiring and cause a stretch reflex w/in the muscle as it goes too far and cause a minor injury. This is due to the muscles tone with the movement. A muscle in stretch is not fully relaxed, they are in a state of "tonus", meaning tension! The contractile fibers themselves are susceptible to trauma.
If you need to stretch the legs, do it when you move slow, not a "bouncing" ballistic fashion.
The legs are full of fluids and are pumped!
