• In this post, I will discuss the what the research says about eccentric overload and eccentric focused training as well as different means of overloading the eccentric phase of movement. (mytpi.com)
  • Concentric hypertrophy is a result of pressure overload on the heart, resulting in parallel sarcomerogenesis (addition of sarcomere units parallel to existing units). (wikipedia.org)
  • Eccentric hypertrophy is related to volume overload and leads to the addition of sarcomeres in series. (wikipedia.org)
