Background & aim: The prevalence of coronavirus worldwide has led to severe limitations including reduced physical activity. The aim of the present study was to determine the effect of a period of inactivity due to the outbreak of coronavirus on the body composition and maximum oxygen consumption of adolescents.
Methods: In the present quasi-experimental study conducted in 2020, 178 male adolescents (mean age 13.85 05 0.057 years) participated voluntarily. Indicators such as height, weight, body mass index and maximum oxygen consumption were measured in two time intervals with an interval of 6 months as pre-test and post-test. Cooper test was used to determine the maximum aerobic capacity. After data collection, first the normality of the data was calculated using the K-s test and then the pre-test data were compared with the post-test using the dependent t-test. Correlated t-test was used to analyze the mean values ​​of pre-test and post-test data.
Results: The results of the present study indicated that lifestyle changes due to the spread of coronavirus caused the mean weight index to change from (50.34 ± 0.79) to (54.25 ± 0.89) and body mass. Change from (19.64 ± 0.26) to (20.26 ± 0.29) and the maximum oxygen consumption likewise changes from (31.04 ± 0.29) to (30.12 ± 0.27). From these effects, it could be understood that COVID-19 causes a significant increase in body mass index (p = 0.001), weight (p = 0.001) and also a significant decrease in maximum oxygen consumption (p = 0.032).
Conclusion: According to the results of the present study, it can be noted that a six-month period of inactivity caused by the outbreak of coronavirus causes changes in body composition and therefore threatens health.
