The aim of this study was to compare the effect of one swimming session in different water temperatures (23, 33 and 38̊ c) on the appetite, calorie intake, calorie consumption, food liking, and the amount of blood lactate in female students. The research design was semi-experimental and 12 female volunteers (mean age 20.83 ± 1.3 yr, BMI 20.46 ± 2.68 kg/m², weight 53.6 ± 5.46 kg) from university students performed the swimming protocol of front crawl in the three temperatures of 23̊c (cold water), 33̊c (normal water) and 38̊c (warm water) for 45 minutes with intensity of 80-85% of maximum heart rate. The amount of appetite and food-liking were recorded by appetite questionnaire and recall of 24 hours of nutritional materials by the subjects. Also, calorie intake and calorie consumption were recorded in the related questionnaires during, before and after performing the protocol by the subjects and were calculated by the album book of nutritional materials and the summary table of body exercise. The concentration of the blood lactate was measured by a lactometer before, immediately after and 3 and 9 hours after performing the protocol. The results showed that one swimming session in different water temperatures (23, 33 and 38̊ c) had no effects on appetite, food-liking, calorie intake and calorie consumption, and water temperatures cannot have an effect on weight loss or gain alone in this type of participants.
