Declarations

:

: The present study is part of a longitudinal research whose methodological protocol for the initial and subsequent waves of data collection was approved by the institutional ethics committee for research at the Faculty of Physical Culture of Palacký University in Olomouc (initial wave: protocol code 25/2024 on 28 February 2021 and subsequent wave: protocol code 102/2023 in November 2023). The ethics committee’s approval of the research protocol included assurances of anonymity, the format of informed written consent, and rules for data security and storage. The accelerometers used were disinfected and sealed in an anonymous envelope with a family code before each start of the 7-day 24hMB monitoring, along with the family diary. Participation in the study was voluntary and free of charge. No participant was penalized in any way for premature termination of 24hMB monitoring, damage or loss of the accelerometer, or failure to return the family diary. Each participating family received their own individualized feedback on the 24hMB results of all their members in the form of printed graphic sheets with accompanying explanatory commentary. Schools received a letter of thanks and a certificate acknowledging their participation in the FAMIPASS study.
