**5. Conclusions**

Finally, based on the results, it can be concluded that COVID-19 home-confinement measures have had a negative impact on PA levels and energy expenditure (MET-min/week), especially among males, overweight participants, and those participants living in an urban area. The results of this study indicated also a significant increase in sitting behaviour among the Kosovan population during the COVID-19 lockdown.

Moreover, significant differences between age categories in MET-min/week were detected, with higher MET-min/week values among young and young adult categories for both pre- and during COVID-19 home confinement conditions. A high number of participants in the young and young adult age categories might have affected the decreased amount of PA levels compared to the latter, which represents the real demographics of the Kosovo population. Nevertheless, MET-min/week values in these two categories were affected the most due to COVID-19 restrictions. The lower number of adult and older adult participants has prevented us from drawing general conclusions regarding the decrease of PA levels for the entire population.

Currently, we are facing the second wave of COVID-19 infections, and these results could have potential important implications to help the decision-making bodies to implement strategies keeping in mind the maintenance of PA levels as crucial part of the public health sector.
