Reviewer 2 Report

Dear Authors,

I was reading your manuscript entitled „Physical activity during the first lockdown of the COVID-19 2 pandemic: investigating the reliance on digital technologies, 3 perceived benefits, barriers and the impact of affect”. The topic you chose is very actual and important. Physical inactivity is one of the leading problems and one of the factors that lead to overweight and obesity. The COVID pandemic without any doubt limits the possibility to exercise and forces many people to stay at home. Your research raised a very important problem, but it requires a major revision before acceptance. I can recommend your manuscript for publication only after major changes, below you will find a detailed description.

Introduction
Authors should give more information about physical activity (PA), there is a description of the situation and many restrictions in COVID pandemic but on the other hand, there is a lack of explanation about the amount of recommended physical activity, the benefits of PA

authors mentioned about three categories of PA - there is a lack of information about them, what was the method of calculation?

the text should be spread into multiple paragraphs to improve readability.

authors should write the recommendation of PA for adult people

line 87-100 – this should go into the methodology section
there was no clear aim of the study

Materials and methods
Line 115-127 – this part should be described in the Results section, not in the subsection sample and procedure

there is a lack of information about tools used in the project (a detailed description of that tools the questionnaires and the mobile application for calculating the PA - duration and time),

there was no information about statistical analysis
Results and Discussion

That sections should be a rethink and revised once again. There is a lack of clarity. Some of the results were put and described in the methodology section, there is a lack of explanation of how those PA categories were calculated what were the units of PA was it only a time duration or should it be also Met-min/week?

what are the other factors which can limit PA

Conclusion
authors should not describe the aim in the conclusion

the conclusion should be rephrased

Authors should add the limitation of the study - what are the limitation of the on-line questionnaires
