Read the summary and the most important questions on Potent myofiber hypertrophy during resistance training in humans is associated with satellite cell-mediated myonuclear addition: a cluster analysis
-
1 Introduction
-
Is the myonuclear domain a fixed entity?
No, it changes with to volume changes. -
What are the main activating factors of satellite cells?
- local and systemic growth factors
- mechanical load
-
Which genes, involved in satellite cell regulation, were differentially regulated according to cluster?
- MGF (activation of satellite cells)
- myogenin (late differentiation)
- cyclin D1 (cell cycle progession)
-
What was the main hypothesis of this study?
How well myofibrils hypertrophy is driven by the size of the pool of satellite cells. -
2 Methods

How often did the participants perform resistance exercise over the course of 16 weeks?
3/week -
How were satellite cells identified?
By using an antibody to the neural cell adhesion molecule (NCAM) -
What growth factor was examined?
IGF-1 including MGF -
