Concentric
pectoralis major
Pectoralis minor.
there are two muscles with pectoralis in their name, Pectoralis Major and Pectoralis Minor. Pectoralis Major is the main muscle of the chest and pectoralis minor is deep to it (so you can't feel it because pectoralis major completely covers it)
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?
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).

Concentric and eccentric movements.
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).
