The difference in vascular reaction to cold among 5 groups of 17 swimmers with experience of 3 years or longer, 13 swimmers with experience of 2 years or less, 12 track and field athletes, 7 gymnasts and 9 non-athletes were studied. Four components which are useful indexes of cold tolerance showed statistically significant differences among 5 groups. From test results of linear comparison between each group, it was determined that athletes compared with non-athletes, and swimmers with other athletes possess better cold tolerance. But there was no significant difference between swimmers with different types in swimming experience years or between outdoor-and indoor-athletes.
