Yes, eccentric contractions when maximal voluntary performed are more forceful than concentric contraction. Inspite the use of more motor units recruited when a eccentric contraction is performed. The greater force might be possible because of the stretch induced force (elastic force). A counter-movement jump is also performed better than a jump without counter-movement.

How is one classed as a mad scientist?
A mad scientist is a term given to a scientist who is insane or eccentric. Historically, there have many mad scientists in film and television, notably Dr. Frankenstein and more recently Dr. Walter Bishop in the Fox television series "Fringe".
How are direct rays different from indirect rays?
direct rays are from the sun and indirect rays are from something else, like it was reflected or something(ex:the moon. It bounces the sun's rays) AKT♥
Why cycle tubes filled with air burst in summer?
The tires are filled with air particles, whose behaviour is governed by what is known as the kinetic molecular theory. In simple terms, during the summer where temperatures are (assumingly) higher, the air particles have more energy (high temp. = higher average kinetic energy). With higher energy, they are moving about inside the tire with higher speed and collisions are more forceful (and common). Thus, these particles tend to occupy more space, and so the tire is forced to expand, eventually bursting.
Is 2.2 kg equal to one pound?
Yes, more or less.Yes, more or less.Yes, more or less.Yes, more or less.
Can you have more than one variable in an experiment?
Yes you can, but the more variables you have the more complex the problem becomes.
Why does eccentric produce more force than concentric?
Eccentric muscle contractions involve the lengthening of the muscle under tension, which allows for greater force production compared to concentric contractions where the muscle shortens. This occurs because the muscle fibers can generate more force during the controlled lengthening process in eccentric contractions, leading to greater tension development.
Is walking downhill a concentric or eccentric contraction of your quadriceps muscle?
Every step, whether going uphill, downhill, or on flat land, involves both an eccentric and concentric contraction.The eccentric contraction occurs when the quadriceps muscles lengthen as they load. In order for your quadriceps to lengthen, the knee must bend. Thus, the eccentric contraction in the walking motion occurs just after you step. This is perhaps more obvious with running than walking. After the foot touches the ground, the quadriceps is loaded eccentrically by the weight of the body as the knee bends.The concentric contraction of the quadriceps occurs then when the muscle shortens, as you push off from your foot. Again, this is probably more obvious with a running motion than walking motion. After the weight of your body has shifted onto the foot that is currently in contact with the ground (with your knee bent), your quadriceps contracts concentrically as the knee unbends and you lift your own body weight.So walking, even downhill, still involves both eccentric and concentric contractions. Walking (and running) downhill can lead to fatigue in your quadriceps due to the greater eccentric loading that occurs when going downhill. The range of muscle motion can be greater and your body is coming from "higher" up (its previous elevation on the hill), which can increase the load as well. As compared with concentric contractions, eccentric contractions can cause more damage to the muscle.
How do concentric muscle contractions contribute to overall muscle strength and performance?
Concentric muscle contractions, where the muscle shortens as it contracts, play a key role in building muscle strength and improving performance. These contractions help to generate force and power, allowing muscles to lift heavier weights and perform movements more efficiently. Over time, consistent engagement in concentric contractions can lead to muscle growth and increased strength, ultimately enhancing overall muscle performance.
Whats difference between eccentric and concentric muscle contractions and examples of when in use?
Eccentric and Concentric contractions are both types of Isotonic Contraction. In isotontic contractions the length of a muscle changes, ie movement occurs, unlike an Isometric Contraction where force is applied but no movement occurs. Concentric contraction is the more obvious type of sixe change a muscle can have, it is when the muscle Shortens to move the Load. For example id one was to bend the elbow whilslt holding a weight (called a Bicep Curl) the Brachialis and, to a lesser extent, the Biceps Brach would shorten and pull the forearm up with the weight. Eccentric contracion is the type that muslce builder who wish to bulk up with inefficient muscle use. This is where the muscle Lengthens under conrtaction. To continue the same example above, imagine the weight was too heavy to hold up so it starts to fall under control. The brachialis and biceps muscles are still contracting trying to hold the weight in place but they are not producing enough force so the load is stretching them out.
What is two or more circles with same center called?
Concentric circles.
Do fast twitch fibers generate more force than slow twitch fibers?
Yes, fast twitch fibers can generate more force than slow twitch fibers because they have a higher capacity for rapid contractions due to their ability to generate high levels of force quickly. Slow twitch fibers are better suited for endurance activities and less forceful contractions.
Two or more circles with the center are?
concentric
What two or more circles with the same center?
They are concentric.
Concentric circles on the disk surface?
Concentric circles, are circles within circles. Each concentric circle on the surface of a disk represents a track, the narrower the circle is, the more data can be stored on the disk.
How can you use eccentric in a sentence?
The eccentric old man washed his hands with pea soup. Pluto's orbit is much more eccentric than the orbit of any major planet.
What are the pie shaped pieces of the concentric circles are called?
Since pies are circular, the pie shaped pieces will be more concentric circles.
Two or more circles with the same center are?
Concentric circles
