Abstract
Exercise is a known contributor to fat loss, its efficacy increasing when combined with an
energy-restricted diet in order to create an energy deficit. Claims exist that exercise
intensity may influence one’s hunger and energy intake post-exercise, affecting the
efficacy of exercise for fat loss. Additionally, women may increase energy intake
following exercise to compensate for the increased energy expenditure more than men.
This study used a randomized crossover design to examine the effect of exercise intensity
on appetite regulating hormones GLP-1 and PYY, and subjective hunger in women, and
compared these results to men following endurance cycling. Both sprint interval cycling
and continuous endurance cycling influenced the concentration of GLP-1 and PYY,
though not differently, and had no influence on perceived hunger. There was no
significant difference in the response of these satiety hormones and hunger between men
and women following endurance cycling.
