PA = physical activity, 6MWT = six-minute walk test, BMI = body mass index.
a
Estimates derived from a linear mixed model adjusted for sex, age at baseline, height and weight, using 244 measurement moments from 118 participants. The analysis of body composition change was not adjusted for weight.
b
Predicted six-minute walk test distance calculated from the equation of Troosters et al. (1999). Data collected from October 2016 to September 2018.
