      There is now convincing evidence which has shown the importance of eccentric contractions in producing muscle hypertrophy (15,24,45,46). It is known that eccentric contractions produces greater injury than concentric or isometric contractions. We also know that if you can induce muscle fiber injury, satellite cells are activated.

      Objectives: To determine whether excess adiposity promotes eccentric or concentric left ventricular (LV) geometric changes and the mechanisms thereof. Background: The principle mechanisms that should be targeted to treat obesity-induced LV hypertrophy (LVH) remain obscure.

      Eccentric exercise promotes greater neural activation compared to isometric and concentric contractions,9 it is considered to be a powerful stimulus to hypertrophy and muscle strength.3 However, the extent of these morpho-functional changes depends on various factors including intensity, frequency and duration of training.10,11

      Eccentric contraction followed by a fast, explosive concentric contraction . What’s the physiology behind it? Stretch-shortening cycle. greater or quicker fiber recruitment with help from muscle spindles. Elastic energy. Hypertrophy Program. Greater volume and variety.

      Total peripheral resistance was highest in concentric remodeling and lowest in eccentric hypertrophy. Conclusions: This study suggest that cardiac hypertrophy might develop in children with mild or moderate form of systemic hypertension. Children with four different patterns of left ventricular geometry differ notably in respect to hemodynamic.

      Cardiac hypertrophy is of two types: concentric and eccentric hypertrophy. Concentric hypertrophy, in which the increased mass is not in proportion to the chamber volume, occurs when there is pressure overload. To overcome the wall stress and the increased systolic pressure, new muscle fibers (myofibrils) are laid parallel to the old ones.
