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).
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).

Let me know about the usage of Eccentric and Concentric pipe intersection in oil and gas industry? What are the major differences and concerns about Eccentric and Concentric pipe intersection in oil and gas industry?
Eccentric exercises are not a separate kind of exercise. Rather, each resistance exercise has two phases. (1) The concentric phase is when the muscle group being trained is shortened, for example, when you raise a barbell doing a standing curl. (2) The eccentric phases is when the muscle group being trained is lengthened, for example, when you lower a barbell doing a standing curl to its original position.

Very depend on the application, concentric pipe had lower pressure drop and better flow distribution. However, in many case, eccentric pipe reducer is installed on propose to allow liquid drainage from reducing in horizontal pipe.
Shoulder extension can involve both concentric and eccentric muscle actions depending on the context. During a concentric action, the shoulder extensors, like the latissimus dorsi and teres major, actively shorten to move the arm backward. In contrast, during an eccentric action, these muscles lengthen under tension while controlling the descent of the arm. Thus, whether shoulder extension is concentric or eccentric depends on the specific movement being performed.
