Most people underestimate the importance of eccentric training because they don't know that there is more mechanical load per motor unit during the eccentric phase of an exercise, and the reason for this is that eccentric contraction involves fewer motor units.

Since fewer motor units are involved during an eccentric contraction (because of the passive resistance offered by the cross bridges), there is more mechanical load per motor unit in an eccentric contraction.

This indicates that muscle activation underpins the process of fiber type shifts, while mechanical loading (tension) determines changes in fiber size.

However, it is possible to tweak your Power Clean workouts by including Cluster Sets to increase time under tension, while maintaining proper Power Clean technique and sufficient mechanical load on the muscles to set a hypertrophic stimulus.

Initially, it was suggested that the higher mechanical loads involved in eccentric training must be responsible and many reviews continue to report this as the most likely explanation (see reviews by Rees et al. 2009; Frizziero et al. 2014).

For dynamic effort, the athlete must be careful not to use too much weight (or too little)- weights that are too light (20 - 30 % of max) do not provide enough mechanical load to require ALL motor units be recruited, and weights that are too heavy (60 + %) can not be moved with enough velocity to train rapid contraction.

Mechanical load increases muscle IGF - I and androgen receptor mRNA concentrations in humans.

This causes the cartilage to lose its thickness and elasticity, which are important in absorbing mechanical loads placed across the joint during movement.

No M7A - 01s or M7A - 02s have been ordered for mechanical load drive duty.

In turn, wind farms can achieve greater power output as an overall plant, and customers can expect to see 5 - 10 percent reduced wake losses and improved mechanical loads due to lower wake turbulence.

These findings indicate that it is highly unlikely that muscle fiber type can be preferentially altered by different types of mechanical loading, except insofar as a smaller volume of training might produce smaller fiber type shifts.

The research is showing promise, and project co-ordinator, Dr. Emile Greenhalgh says the new material is revolutionary because «it does two things simultaneously — it carries a mechanical load and also stores electrical energy.»

«Until now, it was assumed that splitting of the γ» precipitates refines the microstructure during ageing, which would be beneficial for the alloy's stability under thermo - mechanical load.

Located at the tip of the vehicle, the nose cap has to withstand very high thermal and mechanical loads.

This leads to a reduction in the metal's ductility, or its ability to sustain a mechanical load before fracturing.

In addition, recombinant irisin has also been shown to suppress sclerostin, a protein that is involved in bone loss during prolonged lack of mechanical load, such as in bed - ridden patients.

The cellular stretching relates to stresses, which are directed to chondrocytes during the mechanical load.

What are the mechanical loads and stress on the foundation ice?

If you remove the mechanical loading element, the bones think they do nt need to be there and actually get thinner, like what happens with astronauts in space.

The use of heavy eccentric strength training exercise together with more explosive, plyometric - like movements, therefore, seems to provide the ideal combination of mechanical load and neuromuscular recruitment needed to improve the rate of force development.

``... no anatomical structure functions in isolation, and the mechanical load anywhere in the body is distributed through a continuous network of fascia, ligaments and muscles supporting the entire skeleton. . .

Skeletal muscle is a highly malleable tissue that can adapt both morphologically and functionally to chronic alterations in mechanical loading.

However, increases in muscle fascicle length are also likely dependent on the mechanical load incurred by the prime mover, as knee flexion (hamstring only) exercise seems to lead to greater adaptations in the hamstrings than hip extension (hamstring, gluteus maximus, and adductor magnus) exercise, even when muscle length at peak contraction is shorter (Bourne et al. 2016).
