It is generally recognized that moderate exercise induces to increase appetite/hunger in parallel. However, it is not still clear the effect of exercise intensity on these relationships. Therefore, the purpose of this study was to examine as to whether the exercise‐induced alternation of appetite/huger depend on exercise intensity. 12 healthy young male subjects performed cycling exercise at constant work rate (% of VO2max) of 30 % for 20 min (L‐ex), 50 % for 14 min (M‐ex), or 70 % for 8 min (H‐ex), in random order. The total amounts of three works were matched. The subjects were asked the feeling of appetite and hunger at prior‐ and post‐exercise (at 1 and 20‐min) using visual analog scale. The salivary flow and its alpha‐amylase activity were also measured. In H‐ex, appetite and hunger were suppressed immediately after exercise and returned to prior‐level at 20‐min. In L‐ex, both were unaffected by exercise and increased at 20 min. In M‐ex, however, the appetite for 20 min after exercise was close to those in L‐ex, while the hunger did show a similar change to those in not L‐ex, but H‐ex. Salivary flow significantly decreased after exercise in H‐ex. The results indicate that, for the intensity of prior‐exercise, there seem to be two different affected thresholds to appetite and hunger during the following short‐term recovery; i.e., below M‐ex for hunger, but above M‐ex for appetite.
