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).
