Correlation matrix of the PA behaviour variables. The size of the circle is proportional to the correlation strength. Red and blue colours represent negative and positive correlations, respectively. TSB = Time spent in sedentary behaviour; TMVPA = time spent in moderate to vigorous PA; mENMO = average acceleration; IG = intensity gradient; and M8 = the average acceleration above which the most active 8 h of the day were accumulated; M0.25 = the average acceleration above which the most active 15 min of the day were accumulated; PLE = power law exponent (for SB and MVPA); PTT-SB60 = proportion of total sedentary time accumulated in bouts longer than 60 min; PTT-MVPA10 = proportion of total MVPA time accumulated in bouts longer than 10 min; Gini-SB = Gini index (SB); ScalEx-90 = scaling exponent alpha (< 90 min); ScalEx-120 = scaling exponent alpha (> 120 min); AC-24 = autocorrelation at lag 24 h; LZC = Lempel–Ziv complexity; SampEn = sample entropy; and SymDyn-2UV = symbolic dynamics (2 unlike variations)
