Hormonal Responses to Resistance Training
Endocrine Responses and Adaptations to Exercise
Hormonal Responses to Resistance Training
Resistance exercise can transiently alter catecholamines, growth hormone, cortisol and testosterone, depending on recruited muscle mass and session structure.
Acute responses and adaptation
Hormonal responses depend on intensity, duration, training status, fueling, hydration and biological timing. Plasma-volume shifts can change concentrations. Acute release, clearance and tissue sensitivity must be separated before a response is interpreted as altered gland function.
A distinction that matters
The size of a circulating hormone peak does not provide a direct measure of the local muscle growth stimulus.
Track functional outcomes
Training adaptation is assessed through performance, tolerance and recovery over time. A brief anabolic-hormone peak or a ratio of two hormones cannot independently establish later hypertrophy, overtraining or readiness. Persistent changes should be interpreted with symptoms and health context.
