Purpose: The COVID-19 pandemic has had an enormous negative impact on the psychosomatic status of the general population, and especially of more vulnerable populations, such as older people. The present study aimed to assess changes in psychosomatic status before and after the COVID-19 pandemic among emeritus professors over 70 years of age. Materials/Methods: A total of 56 emeritus professors aged 77.4 +- 6.1 (74.1% male) participated in the study. The study was conducted between September 2022 and January 2023, after approximately two and a half years of the COVID-19 pandemic. Sociodemographic characteristics, including socioeconomic status, were assessed in the questionnaire, along with active involvement in academic life and healthcare/sports. Physical and mental fatigue were assessed using a self-report questionnaire, and the impact of fatigue on physical and cognitive function was measured using the Fatigue Impact Scale. Participants evaluated their physical/mental fatigue and physical/cognitive function before and after the COVID-19 pandemic. Results: Among the participating emeritus professors, 15% reported higher levels of physical fatigue (Z 5
1.992, P 5 0.046, r 5 0.28) and mental fatigue (Z 5
2.154, P 5 0.031, r 5 0.31) following the COVID-19 pandemic. A significant difference was found in physical function assessed before and after the COVID-19 pandemic, t(51) 5
2.986, P 5 0.004, g 5 0.22, while cognitive function showed a non-significant difference, t(51) 5
1.265, P 5 0.212, g 5 0.12. After the COVID-19 pandemic, 26.9% of participants reported reduced physical function and 19.2% showed reduced cognitive function. Infection with the COVID-19 virus resulted in increased mental fatigue and reduced cognitive function among the participating emeritus professors. Conclusion: The COVID-19 pandemic (and the introduction of restrictions on social activities) had a substantial and similar impact on the psychosomatic status of emeritus professors at both medical and sports universities. Furthermore, the reduction in physical and mental/cognitive function was exacerbated in those who were infected by SARS-CoV-2. Importantly, however, the overall impact of the COVID-19 pandemic was smaller in the population of emeritus professors than in the general elderly population. This may be due to the better maintenance of physical and mental activity in the former population, thus emphasising the importance of remaining physically and mentally active in old age, especially in the context of critical life events.  Kulcsszavak: elderly, physical fatigue, mental fatigue, physical function, cognitive function
