Complex sequential movements, such as mtb cylcing, requiring a higher skill and must be broken down into phases before an orderly analysis can be delineated!
In other words you can't use a static trainer to find more performance!
Jeremiah wins Massanutten Hoo-ha by 6 min! This single track course puts big demands on handling skills and that is key for a mtb setup!
Before there was front-suspension, clipless pedals, and 9-speed rear cassettes there was the Massanutten Hoo-Ha. An East coast tradition since 1989, the Hoo-Ha has been a showcase event for riders up and down the Eastern seaboard.
Majestic Massanutten Resort is a 6,000 plus acre get-away located in beautiful northern Virginia on the edge of George Washington National Forest. Massanutten Resort offers 25 miles of pristine single-track mountain bike trails.
George Willets has been involved with the Hoo-Ha since it’s inception, first as a racer and now as one of the event’s promoters. Willets can’t say enough about the uniqueness of the Hoo-Ha and the local cycling culture. “Harrisonburg and the local area is really the hub of East Coast cycling. We have an outstanding trail system, which just keeps getting better. The Shenandoah Valley Bicycle Coalition (SVBC) builds all our local trails with the help and input of phenomenal riders like Jeremiah Bishop and the outstanding Sue Haywood.”
We know what goes up, must come down, plus move all around!
We also noted that 2nd was taken by another WN & Myo-facts/Dartfish user "Sam Koerber (Gary Fisher 29er" who was fitted by Andy Applegate in Western NC.
We called Andy Applegate to check how his fitting services are going. He said, super! He loves the fact that there is major fiitng rival service in the very town I grew up in. He also pointed out that he did a 6 hour race and had a 40 min. lead at the end of the event.
YOU CAN'T GET AROUND THE STRUCTURE AND FUNCTION OF SKELETAL MUSCLE!
There are 434 muscles, 75 pairs that work with posture & movement!
A tendon collects and transmits forces from many different muscle fibers onto a small area of bone, the site of the tendinous attachment. The structure of the insertion of the tendon onto the bone and it's behavior under mechanical loading (its size and shape, speed) of loading on it are some of the major factors of its strength.
During normal activity a tendon experiences only 25% of maximal stress; very rapid, unexpected stretches of a tendon are common conditons for tendon rupture. For example, having your heel unexpectedly drop into a hole in the the ground could cause rupture of the
Achilles tendon i.e. heel down pedaling style.
So a word on muscle insertions and levers. When a muscle contracts strongly, it tends to move both of the bones to which it is attached, but to simplify the problem it is usually assumed that the bone moving least is more stationary (more proxiamal) vs. the (more distal) moving bone. The muscle insertion (whether proximal or distal) is the place where the force is applied to the bone.
The musculoskeletal machine is basically an arrangement providing relatively large forces for the rapid manipulation of long lever arms. The mechanical system possesses a low mechanical advantage, with the result that high speeds of motion are made possible only at the price of great exertion.
Its the internal structure of muscles - that is, the arrangement of their fibers-bears an much over looked relation to the force and distance of their contraction. The fiber and physiologic cross-sectional area is needed to better understand what it is you want to do i.e. long & slender muscles are not capable of producing large forces. However, these types of muscle can shorten through a large distance and can have higher shortening velocities. You just need to know what phase you need to start the shortening!
