“…Governments worldwide (UK, Canada, USA, Sweden, Wales) have acknowledged the importance of children's school play spaces as outdoor classrooms, leading to widespread policies to improve school grounds to enhance the quality of children's play (Tranter & Malone, 2004). Movement via play has been described as one of the most natural and powerful avenues of childhood learning (Bilton, 2002) and has been associated with improvements in a wide range of physical, cognitive and social development (Malone & Tranter, 2003;Tranter & Malone, 2004). A number of studies have undertaken school environmental interventions by implementing playground markings (Ridgers et al, 2007;Loucaides, Jago & Charalambous, 2009), greening projects (Dyment & Bell, 2008), extra playground equipment (Lopes, Lopes & Pereira, 2009), sporting equipment (Verstraete, Cardon, De Clercq, & De Bourdeaudhuij, 2006) and household items (Bundy et al, 2009) that have increased children's physical activity during school breaks.…”
