Changes in Physical Activity and the Occurrence of Specific Symptoms of "Long-COVID Syndrome" in Men Aged 18-25.

The aim of this study was to assess the occurrence of non-specific symptoms of "long-COVID syndrome" depending on the physical activity undertaken resulting from the imposed forms of study (distance learning-contact learning); 136 men aged 21.5 ± 1.58 from universities educating students of medical faculties were examined. The difference between the universities was mainly due to the nature of the classes undertaken (classes remotely-hybrid form) in the period from March 2020 to February 2021. Among the respondents, 17% in Group I and 16% in Group II were infected with the SARS-CoV-2 virus, including 50% in Group I with moderate symptoms, and in Group II-most people 45% with mild symptoms. The conducted research clearly shows the impact of the COVID-19 pandemic on students. They show a number of important problems, such as reduced physical activity, as well as increased body weight and time spent in front of the monitor. They also make it clear that the health consequences of the pandemic affect both people who were infected with the SARS-CoV-2 virus and those who did not suffer from this infection.

Changes in Body Mass and Composition of the Body as Well as Physical Activity and Time Spent in Front of the Monitor by Students of the Wroclaw University of Health and Sport Sciences during the Period of COVID-19 Restrictions.

The aim of the study is to assess the impact of changes in daily physical activity during the blockade (March 2020-February 2021) on the mass and segmental composition of the body of young people. Material and research methods: In total, 120 people from the sports and medical university aged 19.8 (±0.8) years, average height 173.2 (±9.2) cm, body mass 66.1 (±12.8), and BMI 19.2 (±5.9) kg/m2. The research was carried out in two stages. The total and segmental body mass of the respondents and the change in physical activity during the pandemic were assessed twice (December 2019, February 2021). There was a statistically significant increase in body mass in men, an increase in total fat mass in women, and statistically significant changes in the distribution of fat mass in both sexes. Conclusions: In the studied group, there was a change in the forms of physical activity from strength and group activity to endurance activity (running forms, cycling.) and individual activity. The subjects showed a statistically significant increase in body fat, regardless of gender, and in the upper limbs in men.
