examined validity in controlled and semi-structured lab settings ( Evenson, Goto, & Furberg, 2015 ). An advantage of these settings is that it enables the use of more robust criterion measures such as portable, indirect calorimetry systems. However, results vary widely based on the nature of activities

Three studies have compared the AP inclinometer function to AG count-based estimates of SB in youth, and have found

) found that VO 2 peak estimated by the PACER test tended to be overestimated in less fit participants and underestimated in more fit participants compared with VO 2 peak measured with indirect calorimetry. In addition, weight status can impact VO 2 peak prediction. Previous research has shown that the
