There are two types of muscle contractions – eccentric and concentric. Eccentric contractions occur when a muscle lengthens as it contracts, while concentric contractions are when a muscle shortens as it contracts. Each type of contraction has its own benefits. Eccentric contractions are often used in weight training because they result in more muscle damage, which can lead to bigger and stronger muscles. Concentric contractions are often used in endurance training because they result in less muscle fatigue. Understanding the difference between eccentric and concentric contractions can help you choose the right type of exercise for your goals.
What is Eccentric?
Eccentric muscle contraction is a type of muscle contraction in which the muscle lengthens as it contracts. Eccentric contractions are important for activities such as walking downstairs, lowering a weight, and Eccentric exercise. In each of these cases, the muscle is opposing the force of gravity or an external load and is lengthening to control the descent. Eccentric contractions are often associated with delayed-onset muscle soreness (DOMS), which is the pain and stiffness felt 1-2 days after performing a new exercise or activity. DOMS is thought to be caused by microtrauma to the muscles and connective tissues, and Eccentric contractions are thought to produce more microtrauma than concentric or isometric contractions. For this reason, eccentric exercise is often used as a method of active recovery following intense workouts. Eccentric contractions can also be used to improve joint range of motion and flexibility.
What is Concentric?
Concentric muscle contraction refers to the contraction of a muscle as it shortens. This type of muscle contraction is responsible for the majority of movement in the body, and occurs when the muscles produce force that is greater than the resistance. Eccentric muscle contraction, on the other hand, occurs when the muscle lengthens while contracting. This type of muscle contraction produces force that is less than the resistance, and often occurs when decelerating or absorbing shock. Eccentric muscle contractions are thought to play an important role in injury prevention, as they help to dissipate energy and reduce damaging impact forces.
Difference between Eccentric and Concentric
Eccentric and concentric muscle contractions are both types of muscular contraction in which the muscles generate force to overcome resistance. However, the two types of contractions differ in terms of how the muscle lengthens or shortens during the contraction. Eccentric contractions occur when the muscle lengthens as it generates force, while concentric contractions occur when the muscle shortens as it generates force. Eccentric contractions are often used during weightlifting exercises, as they help to control the descent of the weight and reduce the risk of injury. Concentric contractions are used during the upward phase of the lift, as they generate the force necessary to move the weight upward. Eccentric and concentric contractions work together to produce smooth, coordinated movements.
Eccentric and concentric are two types of muscle contractions that are used in resistance training. Eccentric contraction is a lengthening of the muscle while it’s under tension, whereas concentric contraction is the shortening of the muscle. Both eccentric and concentric contractions have benefits, but they should be used in different ways to get the most out of your workout. Let’s take a closer look at how each one works and when you should use them.
