What was done
This narrative review synthesized literature on growth hormone (GH) secretion in response to sub-maximal and sprint exercise, evaluating how exercise parameters (type, intensity, duration) and individual characteristics (age, sex, body composition, fitness status) modulate release, alongside proposed regulatory mechanisms.
What was found
The abstract reports no numerical values, effect sizes, or statistical findings. It qualitatively notes that a single bout of exercise is a potent stimulus that markedly elevates circulating GH concentrations, with responses varying by protocol intensity and subject demographics.
Why it matters
Clarifying how exercise parameters alter growth hormone dynamics helps map the endocrine responses and adaptations associated with different forms of physical training.
Limits
The abstract describes a narrative review without reporting systematic search methods, study counts, or quantitative metrics. The underlying mechanisms governing exercise-induced GH release remain incompletely understood.
