GLOSSARY

Applied physiology uses a physiological mechanism to answer a practical question. A cyclist may fatigue sooner at the usual power in a warm room. Heat dissipation, changes in circulation and fluid loss are possible contributors, so record the environment and the response together.

At a constant power, track heart rate and perceived exertion over time. Repeat under comparable starting conditions before attributing the difference to fitness.

Decision example: If both markers rise faster in heat, account for the environment when setting effort or comparing sessions.
