PA was measured using an Actigraph wGT3X+ accelerometer. Participants were instructed to wear the device on their right hip for 7 consecutive days. Accelerometry data were analyzed using the Actigraph Actilife program (v6.12). Wear time was validated using the algorithm developed by Choi et al.32 (link) A valid wear day was considered to be 600 minutes of wear time, while a valid week was defined at least 4 valid days within the 7-day period.33 (link),34 (link) The PA cutoffs established by Troiano et al.34 (link) were used to determine time spent in MVPA (≥ 2,020 counts per minute), with only bouts of MVPA lasting at least 10 minutes being included, as per PA guidelines.35 (link) Weekly MVPA was then calculated using the average daily MVPA among valid wear days, multiplied across the 7 days. According to PA guidelines, adults should participate in at least 150 minutes of MVPA per week.35 (link) Thus, the sample was categorized into two levels for descriptive analysis: those who met PA guidelines and those who did not.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
