GLOSSARY

Estrogen and Thermoregulation
Estrogen participates in hypothalamic thermoregulatory control.

A changing reproductive system

Ovarian function integrates follicular development, gonadotropin input, local signaling and changing steroid feedback. Hormone patterns differ across the cycle and life stages. Timing relative to ovulation or menstrual phase is often essential for interpreting a sample.

Interpreting the mechanism

• Withdrawal and changing feedback contribute to menopausal vasomotor symptoms, which differ from simply generating excess body heat.

Health and training

Cycle disturbance has several possible causes and should not be assumed to be a normal training effect. Energy availability, pregnancy, medication use and endocrine conditions require consideration. Physiological cycle differences alone do not establish one universally optimal training schedule.
