Abstract Background Physical activity participation among preschoolers in childcare settings are low, and interventions to increase physical activity levels have produced mixed results. The Physical Literacy in the Early Years (PLEY) project implemented a six-month childcare-based outdoor loose parts play intervention in childcare centres in Nova Scotia, Canada. The purpose of this study was to examine the impact of the PLEY project on the development of domains of physical literacy (physical activity, physical competence, confidence and motivation, knowledge and understanding) in preschoolers attending childcare centres using mixed-methods. Methods Preschoolers (3–5 years) were recruited from 19 childcare centres in Nova Scotia and centres were randomized (parallel design) to the outdoor loose parts play intervention group (n = 11) or control (n = 8) group for 6 months. Participants, early childhood educators, and assessors were not blinded to group assignment. Quantitative and qualitative measures were used to comprehensively assess the impact of the PLEY project on all domains of physical literacy. At 3- and 6-months, early childhood educators participated in focus groups to assess how the intervention supported the development of 4 physical literacy domains: physical activity, physical competence, confidence and motivation, and knowledge and understanding. Physical activity and physical competence were also assessed with accelerometry and the Test of Gross Motor Development-3, respectively. Results Two hundred and nine preschoolers participated in the study (intervention group: n = 115; control group: n = 94). Accelerometer data showed that while baseline physical activity was similar between groups, children in the intervention group had higher physical activity at 3- (F(1,187) = 8.30, p = 0.004) and 6-months (F(1,187) = 9.90, p = 0.002) post-intervention. There was no intervention effect on physical competence scores. Thematic analysis of focus group data revealed that outdoor loose parts play contributed to development in all 4 physical literacy domains, including increased movement repertoires, social development, and enjoyment of physical activity. No adverse events or side effects of the intervention were reported. Conclusions Participation in the PLEY project was associated with increased development of various domains of physical literacy and perceived physical literacy among preschoolers, and outdoor loose parts play may be encouraged as an effective strategy to increase physical literacy in early learning settings.

Outdoor play with its risks is necessary for optimal child development. Increasing attention is being paid to factors influencing children's opportunities for risky outdoor play, with parent/guardian (hereafter parent) perceptions being an important, under-researched topic. This research explored parents’ perceptions of preschoolers’ risky outdoor play. Interviews were held with 19 parents of preschoolers in Nova Scotia, Canada. Bronfenbrenner's ecological model was used to consider levels of influence related to parents’ perceptions of risky outdoor play. A qualitative descriptive approach identified key themes from interviews. Microsystem-level factors influencing parents’ perceptions included children's age, size, ability to self-assess, and comfort with risk. Mesosystem-level factors were children's companions and supervision during play. Exosystem-level factors included neighborhood location, perceived safety, and house type. Macrosystem and chronosystem-level factors included how parents’ perceptions of weather and season affected children's play, and the influences of higher societal expectations of injury avoidance on children's play over time. Findings can be used to inform strategies to promote children's quality outdoor play through understanding the factors influencing parents’ perceptions of preschoolers’ risky outdoor play.

Purpose: To explore whether parental perceptions of risk and attitudes towards risk-taking during play are associated with preschoolers’ physical activity (PA) and physical literacy (PL). Methods: Nova Scotia preschoolers (35 boys, 17 girls; mean age = 3.8 years) and parents (n=52 pairs) provided data. Linear regressions assessed associations of risk perceptions and attitudes with children’s PA and PL, controlling for children’s age (p<0.05). Results: Perceptions of risk were significantly associated with preschoolers’ PA (r=0.24, p=0.05), and predicted 11.6% of the variance in PA. Findings revealed a significant positive relationship between attitudes towards risky-play and PL (r=0.21, p=0.05), explaining 14.7% of the variance in PL. Conclusion: This evidence supports growing literature around the value of risky-play to children’s development and parents’ influence in risk-taking behaviour.

BACKGROUND: The Physical Literacy in the Early Years (PLEY) intervention is a randomized mixed-methods controlled trial focused on embedding loose parts materials into the outdoor play spaces of regulated child care centres across Nova Scotia. The aim is to evaluate the efficacy of the PLEY intervention versus standard regulated childcare practice in influencing thoughts and behaviors of children, parents, and educators. METHODS: Participating early child care centres (n = 19) were randomly assigned to intervention or control sites. Intervention sites received loose parts kits at the beginning of the project while control sites received kits upon project completion. The kits included items such as rocks, tree cookies, balls, wood planks, tubes, tires, ropes, and pulleys. Children (n = 183 at baseline) had their physical activity (accelerometers) and movement skills (TGMD-3 and PGMQ) measured before and after the intervention. All centres provided responses to environmental surveys (Go NAP SACC and Site Context Questionnaire), and educators in intervention sites participated in focus group and photovoice sessions. Educators were also provided with a full day professional development opportunity (plus ongoing mentoring) focused on physical activity, physical literacy, outdoor play, risk-taking, and loose parts. Parents participated in an interview addressing active outdoor play, physical literacy, and attitudes towards risk taking during play. DISCUSSION: This study will provide a better understanding of how integrating loose parts materials into outdoor play spaces impacts children’s health, and the impact on educator and parent attitudes, beliefs, and understanding around physical literacy, active outdoor play and risk-taking during play.

The objective of this study was to describe the levels and bouts of physical activity (PA) and sedentary behaviour (SB) among preschoolers in Nova Scotia, Canada, and the proportion meeting PA and step guidelines. Children (75 boys, 49 girls; mean age = 4.2 (range = 3–5 years)) participating in the Physical Literacy in the Early Years (PLEY) study provided data. Average time (minutes, % of day) spent sedentary, in light PA (LPA), moderate-to-vigorous PA (MVPA), and total PA; average frequency; and duration of bouts of MVPA (≥5 min, ≥10 min) and sedentary bouts (≥10 min) per day were determined using published cut-points, using 15-s epochs. The proportion of children meeting PA and step guidelines was determined, and differences by sex explored. Children spent the majority (70.8%) of their day active; nearly all (≥97%) met PA guidelines. Most children met step guidelines on a weekly basis, but not daily. Only LPA differed by sex (greater in girls; p = 0.001). Little time was spent in sustained SB (bouts ≥10 min). Boys had greater and longer bouts of MVPA and spent more of their day in these (p < 0.05). Girls spent less time in sustained SB (p = 0.009). This is the first study to describe the PA and SB of Nova Scotia preschoolers using accelerometry. Findings suggest preschoolers spend the majority of their day active, and that there are sex-related differences in PA and SB, warranting further examination.

It is important to consider physical activity and movement in early life to ensure children establish and maintain healthy physical activity patterns. Recent evidence has highlighted the importance of outdoor play and the childcare environment. Active outdoor play, especially free play, supports independence, self-regulation and allows children to explore their world and make decisions. Loose parts or open-ended materials are natural or synthetic resources that can be used in more than one way, allowing children to experiment through play. Incorporating loose parts into play environments creates opportunity for new play experiences. Despite growing evidence supporting loose parts play, the perspectives of childcare providers on the benefits and challenges of this type of play have been overlooked. The purpose of this study was to identify the benefits and challenges of incorporating loose parts play into the outdoor environments of childcare centres, from the perspectives of educators who took part in the Physical Literacy in the Early Years (PLEY) project. PLEY is a larger, mixed methods intervention study with the goal of evaluating a loose parts intervention in early childcare settings. This portion of the project used qualitative description to explore educators' perspectives. Data were collected using focus groups (n = 15) with early childhood educators (n = 3–5 in each group). Thematic analysis was used to identify five themes relating to benefits, and four themes relating to challenges. Benefit themes included: loose parts enable children to take risks; loose parts spark creativity and imagination; loose parts contribute to problem-solving abilities; loose parts cultivate independence and confidence; and loose parts build relationships and leadership. Challenges included: apprehension of loose parts; loose parts as a novelty; sustainability of loose parts; and loose parts present challenges with storage. Overall, we found educators perceived outdoor loose parts play to have multiple social and cognitive benefits for preschool-aged children that are critical for optimal growth and development, and overall health and wellness.

Documented gaps in outdoor play and learning training in early childhood education highlight potential opportunities for the development of collaborative strategies among early years and health sectors. This study describes the early childhood education outdoor play and learning data from 16 Nova Scotia Child Care settings.

The Physical Literacy in the Early Years project is examining whether preschoolers who participate in active outdoor play, facilitated by educators trained in embedding loose parts into outdoor spaces, enhances their physical literacy. The study’s protocol will be shared, along with the potential impact on policy/practice changes in early years.

National accelerometry-measured physical activity data on preschoolers exist, yet the physical activity of Nova Scotia preschoolers is largely unknown. This study describes the accelerometry-measured activity of Nova Scotia preschoolers and adherence with activity guidelines. Results revealed children spent the majority of their day active, and all children met the guidelines.
