Effects of Cold-Water and Cold-Air Exercise on Appetite, Energy Intake, and Food Preference

This study investigated whether exercising in cold environments affects appetite, energy intake, and food preference compared with exercising in thermoneutral conditions. Eleven healthy males completed five laboratory trials as part of a crossover study: a control trial and four exercise trials performed in cold-water (16°C), thermoneutral water (35°C), cold-ambient air (6°C), and thermoneutral ambient air (26°C). Appetite responses were assessed throughout each trial, and participants were provided with an ad libitum meal after exercise to measure energy intake. Food preference was assessed using the Leeds Food Preference Questionnaire. The study aimed to determine whether environmental temperature and exercise medium influence acute post-exercise eating behaviour.
