Recovery and movement
Exercise habits before infection, including exercise frequency, exercise intensity and exercise duration, were investigated among all positive trans positive interviewees. 269 (26.55%) never exercised before infection, 345 (34.06%) exercised 1-2 times a week, and 399 (39.39%) exercised 3 times a week or more. Those who exercise three or more times a week, 30min or more each time, lasting for more than three months are called regular exercise.[11] 319 people (31.49%) have regular exercise habits, and 694 people (68.51%) have irregular exercise habits. 763 people, or 75.32 percent, stopped exercising after contracting COVID-19.
The symptoms of general fatigue, diarrhea or vomiting during infection were significantly correlated with regular exercise. The duration of general fatigue in regular exercise group (5.27±4.37) was significantly less than that in irregular exercise group (6.02±4.50, P<0.05). The duration of diarrhea or vomiting in exercise group was shorter than that in no exercise group (P<0.05).
According to the 24h exercise guidelines for adults issued by the Canadian Health Authority, people who sit more than 8h are defined as sedentary.[12] The sedentary of all respondents is 6.5±2.77h, and 402 people (39.68%) are sedentary group.
According to the exercise conditions, there was no significant difference between the fever temperature during infection and regular exercise or not, and there was no significant difference between the regular exercise group (7.18±3.04) and the irregular exercise group (7.54±3.23, P=0.171). However, the days of fever remission in regular exercise group (1.81±1.91) was significantly shorter than that in irregular exercise group (2.02±1.95, P<0.05). According to sedentary behavior, the number of negative days in the non-sedentary group (7.32±3.24) was significantly less than that in the sedentary group (7.66±3.06, P<0.05), and the number of fever-reducing days in the non-sedentary group (1.88±1.95) was significantly less than that in the sedentary group (2.07±1.91, P<0.05) (Fig.3).
