What is the Meaning of Muscle Hypertrophy?

The physiological increase in the size of skeletal muscle fibers, resulting from an increase in the cross-sectional area of existing myofibrils, rather than an increase in the number of fibers. This adaptation is a primary response to mechanical loading and is strongly mediated by anabolic signaling cascades. Hormones like testosterone and growth hormone play pivotal roles in facilitating this growth.

What is the Origin of Muscle Hypertrophy?

Derived from Greek roots: hyper (over, above) and trophē (nourishment), literally meaning excessive nourishment or growth of tissue. In clinical science, it specifically denotes an increase in muscle bulk beyond normal physiological parameters due to specific stimuli.

What is the Mechanism of Muscle Hypertrophy?

Resistance exercise induces microtrauma, triggering satellite cell activation and subsequent protein synthesis via the mTOR signaling pathway. Anabolic steroids and endogenous testosterone enhance this process by increasing the nuclear availability of androgen receptors within muscle tissue. This mechanism results in a net positive protein balance, leading to increased contractile protein deposition and subsequent muscle fiber thickening.
