“…In fact, one significant barrier to physical literacy realizing its potential is the diverse, sometimes conflicting, definitions that different groups adopt for physical literacy (Shearer et al, 2018). This situation has been critiqued as causing confusion and conflict, and even for being too divergent from Whitehead's 'original' intended meaning (Hyndman & Pill, 2017;Robinson, Randall, & Barrett, 2018); but of course, simply because a concept has been formulated before does not prevent other researchers from exploring and testing that formulation, or from seeking approaches that are more suitable to a specific local context (e.g., Whitehead, 2010). Recent systematic reviews (Edwards et al, 2017;Edwards, Bryant, Keegan, Morgan, & Jones, 2018) and narrative overviews (Green, Roberts, Sheehan, & Keegan, 2018;Shearer et al, 2018) have analyzed and compared the differing approaches to conceptualizing and operationalizing physical literacy.…”
