3、 exhaustion swimming speed and swimming time of mice intermittent exposed in cryogenic freezing rain and snow weather, and clarifies the correlation between cryogenic freezing rain and snow weather environment meteorolog

4、ical elements and sport ability. Thus it provides the reference for the work and training in cryogenic freezing rain and snow weather. Methods：This study selects 80 Kunming male mice which are 8-week-old, fed in the norm

5、al temperature environment for one week. According to body mass, all the mice are randomly divided into 8 groups: the control group: 1 day exposed group (continuous intermittent exposure 1 day), 2 days exposed group (con

6、tinuous intermittent exposure 2 days), 3 days exposed group (continuous intermittent exposure 3 days), 4 days exposed group (continuous intermittent exposure 4 days), 5 days exposed group (continuous intermittent exposur

7、e 5 days), 6 days exposed group (for continuous intermittent 6 days) and 7 days exposed group (for continuous intermittent 7 days), 10 mice in each group. Control group are raised 7 days in the normal temperature environ

8、ment, and then do exhaustive swimming experiments. The swimming speed and time of mice are recorded. The exposure group exposed in the cryogenic freezing rain and snow weather for 1 hour a day, the rest of the time they

9、were raised in the normal temperature environment. The seven exposed groups continuously intermittent exposure in the corresponding number of days, and then do exhaustive swimming experiments. After that the swimming spe

10、ed and swimming time of mice in each group are recorded. Result: (1) Compared with the control group, the swimming time of mice in the1、 2、 3、 4、 5 and 7 day exposed group are decreased （P＜0.01). But 6 days’ exposed grou

11、p is increased. There was no significant difference. (2) Compared with the control group, the swimming speed of mice in the 1、2、5、6 and 7 day exposed group are increased. However, 3 and 4 day exposed group are decreased.

12、 There was no significant difference. (3) meteorological in the dew point (R2 = 0.93513) had the greatest influence on the mice swimming time, (R2 = 0.65059), temperature （R2=0.65059） is the second， THI （R2=0.20393） had

13、the third influence in mice swimming time, and the influence of humidity（R2=0.08959）had minimal effects on the mice swimming time. (4) Meteorological in the dew point (R2 = 0.39533) had the greatest influence on the mice
