Context:
Being physically active during the early years (age 0-6 years) is vital for healthy development. Identifying correlates and determinants of physical activity (PA) is crucial to guide effective interventions. This systematic review synthesized studies investigating potential correlates and determinants of PA during the early years, account...
This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proporti...
Measuring physical activity (PA) and sedentary time (ST) in young children (<5 years) is complex. Objective measures have high validity but require specialist expertise, are expensive, and can be burdensome for participants. A proxy-report instrument for young children that accurately measures PA and ST is needed. The aim of this study was to asses...
This research examined the influence of sit-to-stand desks on classroom sitting time in primary school children.
Pilot controlled trials with similar intervention strategies were conducted in primary schools in Melbourne, Australia, and Bradford, UK. Sit-to-stand desks replaced all standard desks in the Australian intervention classroom. Six sit-to...
Introduction Physical activity, particularly moderate-to-vigorous physical activity (MVPA) is a key lifestyle behaviour for good health. For children in the early years (2-5 years) engaging in high levels of MVPA could lead to improved bone/skeletal development, adiposity and metabolic status. MVPA has also been found to track from early childhood...
Introduction: Whole system approaches to public health challenges such as low physical activity levels have the potential to create sustained behaviour change at a population level and tackle health inequalities. However, there is currently little evidence of the nature or effectiveness of adopting whole system approaches. This study evaluated whet...
Background
There is a lack of evidence of stakeholder perspective and understanding of physical literacy among relevant stakeholders from England. As part of research commissioned by Sport England to develop a physical literacy consensus statement for England, this study presents findings from the first national consultation with stakeholders in En...
Purpose
Physical literacy has gained considerable traction across physical activity, sport, health, and education sectors, leading to an abundance of definitions and interpretations worldwide. However, implementing and advocating for physical literacy becomes challenging when the concept holds different meanings for different individuals and organi...
Global guidance is driving systems thinking to the forefront of research, policy, and practice. To achieve this, we need to consider how things work to ensure successful implementation. The use of the implementation research logic model as a contemporary tool to aid the planning, reporting, synthesizing, executing, and evaluating of the novel Creat...
PURPOSE: Physically Active learning (PAL) and Movement Breaks (MBs) are popular methods for encouraging increased Physical Activity (PA) within curriculum time. Both have also been claimed to enhance pupil’s cognitive and academic performances. However, existing research evidence is inconsistent in finding support for such claims and there are no s...

Evidence suggests that children struggle to acquire age-appropriate fundamental movement skills (FMS), despite their importance for facilitating physical activity. This has led to calls for routine school-based screening of children's FMS. However, there is limited research exploring schools' capacity to conduct such assessments. This study investi...
Sedentary behaviour (sitting) is a risk factor for adverse health outcomes. The classroom environment has traditionally been associated with prolonged periods of sitting in children. The aim of this study was to examine the potential impact of an environmental intervention, the addition of sit–stand desks in the classroom, on school children’s sitt...
Background
A large proportion of children are not able to perform age-appropriate fundamental movement skills (FMS). Thus, it is important to assess FMS so that children needing additional support can be identified in a timely fashion. There is great potential for universal screening of FMS in schools, but research has established that current asse...

Regular physical activity is important for children’s physical and mental wellbeing and academic performance. Unfortunately, too many children are not moving enough. Globally, 50% of children don’t meet the internationally-recognized target of 60 minutes of daily moderate-to-vigorous physical activity. This rises to four out of five children in wes...
Traditional classroom furniture dictates that children predominantly sit during class time. This study evaluated the impact of providing standing desks within a deprived UK primary school setting over 8 months using mixed-method approaches. All children within a Year 5 class (9-10-year-olds, n = 30) received an adjustable sit-stand desk, while anot...
Background
Fundamental Movement Skills (FMS) play a critical role in ontogenesis. Many children have insufficient FMS, highlighting the need for universal screening in schools. There are many observational FMS assessment tools, but their psychometric properties are not readily accessible. A systematic review was therefore undertaken to compile evid...
Background
Evidence suggests that significant numbers of school children fail to acquire age-appropriate fundamental movement skills (FMS), despite the importance of FMS in facilitating participation in physical activities. This has led to calls for an increase in routine screening of children’s FMS in school settings. However, there is limited res...

Questions
Question (1)
I am interested in using a physical activity tracker across a large population of children (aged 8-14), which would not only allow children to track their own activity and for researchers to implement behavior change techniques (goal setting etc), but also for researchers to collect the real-time data as well.
Does such technology exist or are current trackers reliant upon the participant to upload data to an app and then researchers access the data from a central point/hub?
Any guidance would be great
