GLOSSARY

Adiponectin Isoforms
Adiponectin circulates in several oligomeric forms with different biological associations.

Adipose tissue sends information. Adipose tissue contains adipocytes, vascular cells and immune populations with distinct secretory contributions. Depot, energy status and inflammation influence the resulting endocrine profile. A circulating association does not establish the producing cell or prove a causal metabolic effect.

A distinction that matters. Total concentration does not reveal the distribution or activity of every isoform.

Appetite is integrated. Hunger and food intake reflect endocrine signals together with neural reward, meals, sleep and environment. Low energy availability can occur at different body sizes. No single adipokine concentration can independently determine an athlete's fueling requirements.
