Studies that have analyzed the association between the different movement behaviours and fundamental movement skills (FMS), have considered it in an independent manner, disregarding the compositional nature of 24-hour movement behaviours (24h MB). The aim of this study was to investigate the relationship between the 24h MB and FMS in preschoolers using a compositional data analysis approach. Two hundred and four preschoolers of both sexes, provided assessed physical activity (PA) and sedentary time (ST) data (Actigraph wGT3X), and FMS assessments (TGMD-2). Sleep duration (SD) was reported by parents through interview. Association of daily time composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When data were considered as a 24h MB composition based on PA, ST and SD, adjusted for age, BMI and sex, the composition significantly predicted locomotor (r2=0.31), object (r2=0.19), and total motor score (r2=0.35), respectively (all P<0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. It is evident that achieving adequate balance between movement behaviours over the 24-hour period, and its’ relationship with both locomotor and manipulative skills should be acutely considered and further investigated in early childhood
