objective PA assessment. Nonetheless, these findings highlight the importance of considering different strategies to target weekday and weekend day PA promotion. Although the present study had numerous strengths, such as the objective measurement of PA, precisely matched healthy counterparts, and the novel

effects of gender and psychosocial factors on changes in PA over time, with a representative sample of children and objectively measured PA. This analysis used data from a prospective cohort study of changes in PA with objective measurement of PA to consider gender differences in changes in PA in a

The validity and reliability of the accelerometer have been established previously in children and adolescents ( 20 ). Participants were instructed to place the

We hypothesized that self-report measures assessing functional mobility, balance confidence, and prosthetic use would each independently help to explain

On the other hand, accelerometers capture daily PA but do not take into account in which context this PA happened, such as sports participation. The Likert scale used to categorize both weekly volume and previous time of engagement is a

levels of MVPA during adolescence is important. Objective measurements of body size ( 2 , 21 , 23 , 31 ) and subjective perceptions of body size ( 15 , 28 , 32 , 33 ) have been consistent targets in studies exploring barriers to physical activity. For example, studies have found that objectively

Objective measurement of habitual physical activity using accelerometers or, at a minimum, a survey (requires parental assistance) would be beneficial. More comprehensive use of heart rate monitors and participant rating of

Wrist-worn accelerometry has become a feasible option for the objective measurement of physical activity in large-scale epidemiological studies, such as Pelotas birth cohorts, the UK Biobank, and Whitehall II ( da Silva et al., 2014 ; Doherty et al., 2017 ; Menai et al., 2017 ). Additionally
