Resistance Training Endocrine Response

Meaning

Resistance Training Endocrine Response describes the acute and chronic changes in the secretion and action of regulatory hormones that occur as a direct result of engaging in structured exercise that involves muscular contraction against an external load. The acute response includes transient, significant elevations in anabolic hormones, such as testosterone, growth hormone, and cortisol, immediately following a session, which mediate signaling for repair and adaptation. The chronic response is characterized by long-term improvements in baseline hormone sensitivity and receptor density in target tissues, leading to sustained gains in muscle mass and bone density.
