The releasing of the muscles slowly to become longer under the effect of a load is known as eccentric contraction
An example of eccentric contraction is the elongation of the curl biceps as the load of the dumbbell is lowered down after lifting, such that while in the process of lowering rather than dropping the dumbbell down the biceps remain in contraction so as to maintain control of the descent
Along with eccentric contraction, isometric contraction and concentric contraction make up the three phases of muscles and tendon movement.
Cardio is a term used for the heart. When people talk about cardiovascular health they mean your heart and blood stream. Pulmonary talks about the lungs. This comes from the latin word Plumo which means lungs.
Athletes should stay away from tobacco use because it has been scientifically proven that smoking, vaping, and chewing tobacco can cause multiple types of cancers and can even decrease your lung compacity making it harder for you to breathe.
