Various adjustments within their daily habits caused changes to the population’s sleep quality and physical activity level. The purpose of this study is to research study the correlation between physical activity level and sleep quality in preclinical medical students in Udayana University. This study was conducted using an analytic cross-sectional method and consecutive sampling technique involving 282 preclinical medical students of Udayana University from academic year of 2018, 2019, and 2020. The data were obtained via the scores of Global Physical Activity Questionnaire and Pittsburgh Sleep Quality Index. The GPAQ score showed that 123 (43.6%), 127 (45%), and 32 respondents (11.4%) respectively had a low, moderate, and high level of physical activity. Meanwhile, the PSQI score showed that 102 respondents (36.2%) had a good sleep qualityquality, and 180 respondents (63.8%) had a bad sleep quality. The average PSQI score of the respondents was 5.23 (cut off = 5). The correlation between the level of physical activity and sleep quality was analyzed using the Chi-Square method and was deemed found innon significant (p = 0.172; 2-sided). The majority of preclinical medical students had low-to-moderate level of physical activity and bad sleep quality. No significant correlation was found between level of physical activity and sleep quality in preclinical medical students during the COVID-19 pandemic. Further studies are needed to determine other factors that might affect physical activity level and sleep quality within the population.

College students is are one of the most susceptible populations which could be seen from the findings of a decrease in physical activity level and sleep quality within its midst 1,2 . Previous literatures have reviewed the effects of the pandemic on global health from various angles, including direct causes such as physical activity level; sleep quality; depression and anxiety levels, as well as other social factors such as familial issues; unrest caused by misinformation; financial stress; job instability; decreased global economic output; et cetera 1-3 . To a certain extent, the population of medical students is also likewise affected. In this manner, physical activity level and sleep quality are two simple health indicators that could be used to infer the extent of the effects of COVID-19 within the population. Previous studies have produced results which
