GLOSSARY

Endocrine Dysfunction is disordered hormonal production, regulation or action.

Hormonal imbalance is a broad description rather than a standalone diagnosis from an online symptom list. Deficiency, excess and resistance differ, and reference ranges depend on method, age and conditions. Medicines, illness, sleep and energy status also matter. Persistent symptoms need appropriate assessment to identify causes; choosing supplements or manipulating hormones from one isolated test cannot replace evidence-based evaluation or establish a universal athletic hormone target.

Hormonal axes use feedback and often pulsatile and time-dependent patterns. A rise can be compensatory and a decline temporarily adaptive, neither diagnosing disease without context. Hormone ratios depend on numerator, denominator, timing and units. Sports nutrition does not aim to maximize every hormone; the practical goal is adequate supply and appropriate physiological responses, evaluated with health and performance rather than an isolated ratio or peak.

Synthesis, storage, secretion, transport and clearance are distinct processes. Blood concentration reflects entry and removal rather than directly measuring secretion; exercise-related plasma-volume changes can also affect it. Half-life depends on hormone form and method and is not identical to the duration of all effects. Comparisons therefore need sampling time, previous food and recent activity standardized or recorded rather than interpreting isolated concentration differences without context.
