  1. a 95% confidence interval
  2. b Key indicators of the distance regression model: F(6.130) = 10.53, p < 0.001, R2 = 0.327
  3. c Key indicators of the VO2max regression model: F(6.130) = 17.26, p < 0.001, R2 = 0.443
  4. * Statistically significant (p < 0.05)
  5. Cumulative distance (in m) and VO2max (in ml kg-1 min-1) as objectively measured outcome variables and questionnaire scores on physical functioning and physical role as self-reported explanatories in sample 1 from a study carried out in Grand Moutcho school, Agboville, Côte d'Ivoire, in early 2010 [17]. Sample 1 with n = 137 observations (79 boys, 58 girls) includes all children with complete questionnaire, parasitological, clinical and shuttle run test results (see also Figure 1). Ambient air temperature (in°C) and relative humidity (in %) as well as participants sex (reference: female) and age (in years) were included as potential confounders.
