Sitting Ducks: Physical Activity And Diet-Related Interventions In The "Peri-Covid-19" Period

The global coronavirus disease 2019 (COVID-19) poses specific challenges for physically-active cohorts of people. Students, adults, and the elderly need to adapt and seek proper physical activity and diet-related interventions to use their spare time effectively and/or improve their health. Not surprisingly, the existing body of knowledge reveals a consensus on the importance of proper nutrition and physical activity in the so-called "peri-COVID-19" period (i.e., before, during, and after the coronavirus pandemic); however, we explain context-dependent considerations. Therefore, the present study provides a brief review of current knowledge of physical activity and nutrition and develops a three-stage conceptual model for context-based guidelines. The model pinpoints the relative importance of parameters of physical activity in three different periods. In addition, we provide illustrative examples of appropriate training regimens. Our findings complement the agenda for individuals willing to establish desired physical condition and nutrition after the pandemics. Finally, we reveal the supportive role of diet-related interventions and supplements in the peri-COVID-19 period.
