Give examples for concentric and eccentric muscle contractions in gait cycle?

while kicking a football, the Quadriceps muscle contracts concentrically to straighten the knee and the Hamstrings contract eccentrically to decelerate the motion of the lower limb.
In concentric muscle contraction muscle length decreases along with contraction of the fibres while in eccentric muscle contraction the muscle length increases.

What is better concentric or eccentric exercise?
In Resistance Training, concentric and eccentric contractions are two movements done by opposing muscles. Eccentric contractions are said to cause delayed onset of muscle sorennes( DOMS).
What are the three types of contractions of skeletal muscle?
isotonic concentric eccentric isometric
What are some ways muscle contractions can graded?
Muscle contraction can be: Concentric, Eccentric, Static.
The strongest muscle contractions are normally achieved by what?
The strongest muscle contractions are normally achieved by increasing the stimulation up to the maximal stimulus. There are various classifications of contractions, including eccentric and concentric.
What type of muscular contraction is leg extension?
There are 3 types of muscle contraction in the leg extention and they are Concentric, Isometric, and Eccentric contractions.
What phase is the muscle the strongest eccentric concentric or isometric?
Isometric
Is a squat eccentric or concentric?
Both. Concentric: Exercise where the muscle is contracted under a load Eccentric: Exercise where the muscle is stretched under a load. So when you squat down its eccentric, when you come back up its concentric. Most exercises are both, with a few exceptions (i.e. jumping of a wall is mainly eccentric, while a punch is mainly concentric. Eccentric contraction is associated with increased muscle growth, but also DOMS (Delayed onset muscle soreness, when your muscles are very sore after a workout).
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.
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.
If enough muscle fibers contract to make the muscle as a whole shorten in length the muscle is said to exhibit contractions?
concentric
Are eccentric contractions more forceful than concentric contractions?
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.21.

What are the types of contractions doing a situp?
A sit up is an eccentric muscle contraction.
