The Impact of the Daily Mile™ on School Pupils' Fitness, Cognition, and Wellbeing: Findings From Longer Term Participation

Comparing the impact of "The Daily Mile™" vs. a modified version on Irish primary school children's engagement and enjoyment in structured physical activity

Introduction

The repetitive nature of The Daily Mile may affect long-term engagement. This study compared the impact of The Daily Mile with a modified version on engagement and enjoyment of structured physical activity.

Methods

A ∼7-year-old and ∼11-year old cohort from six primary schools participated in this study, which primarily evaluated pre- to post-assessment changes within each group. Two schools were assigned to The Daily Mile (n = 102 children; M = 8.81 years, SD = 1.97), two schools to the modified version (n = 87; M = 9.16 years, SD = 2.76), and two schools served as controls (n = 79; M = 10.05 years, SD = 1.9) for 10-weeks. Health assessments conducted included cardiorespiratory fitness (550 m Run), fundamental movement skills (Test of Gross Motor Development-2), and health-related quality of life (KIDSCREEN-27). Accelerometers measured school-based physical activity, while enjoyment was assessed using a modified PACES questionnaire. Post-intervention focus groups (n = 10) included teachers and children.

Results

Both the Daily Mile (∼7-year-old: p < 0.001; ∼11-year-old: p = 0.004) and its modified version (∼7-year-old: p < 0.001; ∼11-year-old: p < 0.001) had a significant impact on cardiorespiratory fitness. Participation in the modified version led to significant improvements in fundamental movement skills (∼7-year-old: p = 0.034; ∼11-year-old: p < 0.001), unlike participation in The Daily Mile (∼7-year-old: p = 1.000; ∼11-year-old: p = 0.807). A significant positive effect on health-related quality of life was attributed to participation in the modified version (p = 0.036), but not to The Daily Mile (p = 0.205). Enjoyment scores were significantly higher for the modified version (4.61 vs. 4.43; p = 0.024).

Discussion

Participation in The Daily Mile is associated with improved health outcomes. Nevertheless, modifying the initiative to include greater variety has the potential to offer broader health benefits, longer engagement, and increased enjoyment. Future research should explore the long-term implementation of this modified version in schools.

Evaluating the Perceived Health-Related Effectiveness of 'The Daily Mile' Initiative in Irish Primary Schools

Many Irish primary school children do not meet recommended physical activity (PA) guidelines. The Daily Mile (TDM) is a primary school initiative designed to increase children's PA output. This study evaluates TDM's perceived effect on Irish primary school children's health-related metrics. A mixed-methods study, comprising two data collection phases, used the RE-AIM framework to evaluate TDM. Phase One involved teachers, principals and classroom assistants (n = 191) from TDM-registered schools completing a questionnaire. Two TDM-registered schools participated in Phase Two, where (i) interviews were conducted with each principal, (ii) a teacher sub-sample (n = 4) participated in a focus group, and (iii) a child sub-sample (n = 14) participated in separate focus groups. TDM was perceived to positively impact the markers of children's health, including their PA behaviour, physical fitness and social well-being. Inclement weather (66.5%) and a lack of time (56.5%) were reported as the top-ranked implementation barriers. Moreover, TDM's repetitive nature often left children feeling disinterested and resulted in some teachers modifying the initiative to maintain engagement levels. Maintaining the long-term implementation of TDM and its health benefits in primary schools may require bespoke amendments to the original format to preserve children's engagement.

Commentary: Comment and reflection about Mental health outcomes of the Daily Mile in elementary school children: a single-arm pilot study. The implementation of the Daily Mile in the school context

In 'Mental health outcomes of the Daily Mile in elementary school children: a single-arm pilot study', Arkesteyn et al. (Child and Adolescent Mental Health, 2022) discussed and investigated the effect of a classroom activity break, named The Daily Mile, on pupils' self-esteem, self-perception competence, and mental health. Starting from the interesting and novel results of Arkesteyn et al. (Child and Adolescent Mental Health, 2022), this comment focuses on the concurrent evidence about the effect of The Daily Mile on pupils' physical and mental health. Overall, this comment would reflect and critically review considerations for future research on the topic and to adopt it in the school context.

A systematic review of the effect of The Daily Mile™ on children's physical activity, physical health, mental health, wellbeing, academic performance and cognitive function

BACKGROUND

A minority of children in the United Kingdom meet the recommended physical activity guidelines. One initiative which has been introduced to try and increase the physical activity levels of school children is The Daily Mile™ (TDM). The aim of this review was to determine the effect of TDM on children's physical activity levels, physical health, mental health, wellbeing, academic performance and cognitive function.

METHODS

Six databases were systematically searched from TDM's inception (2012) to 30th June 2022. Studies were included if they involved school-aged children (aged 4-12 years), taking part in TDM and measured at least one pre-defined outcome.

RESULTS

Thirteen studies were included from the 123 studies retrieved. Longer-term participation in TDM was found to increase moderate-to-vigorous physical activity and physical fitness. None of the studies reported a significant change in Body Mass Index or academic performance. An acute bout of TDM was not found to improve cognitive function, however one good-quality study reported that longer-term participation in TDM increased visual spatial working memory. There was evidence from one fair-quality design study that TDM can improve mental health in the short term. There were no significant effects on wellbeing, however scores on self-perceptions improved mainly for children with low baseline self-perceptions.

CONCLUSION

There is evidence to show that TDM can increase physical activity and physical fitness. However, higher-quality research, with adequate participant randomisation and longer-term, post-intervention follow-up is needed to ensure that any changes accurately reflect the components of TDM and are sustained beyond an intervention time frame. Policy recommendations of TDM increasing PA levels in the short term are supported by the evidence in this review. However, long-term improvement on mental health, wellbeing, academic performance and cognitive function requires further good-to excellent quality research. Promisingly, several protocol articles that include randomised controlled trials with long term follow-up have been published. These higher-quality design studies may provide a stronger evidence-base on the effects of TDM on children's health and should underpin future recommendations in public health policy.

Effect of 5-weeks participation in The Daily Mile on cognitive function, physical fitness, and body composition in children

The aim of the present study was to determine the effect of 5-weeks participation in The Daily Mile on cognitive function, physical fitness, and adiposity in primary school children. In a quasi-experimental study, one class from each school completed The Daily Mile (n = 44) or acted as a control group (n = 35). Baseline measures included cognitive function tests (Stroop test, Sternberg paradigm, Flanker task), physical fitness (multi-stage fitness test) and body composition (BMI percentile, waist:hip circumference, sum of skinfolds). The intervention group completed 5-weeks of The Daily Mile. Follow-up measurements were completed within 48-h of the last training session. Data were analysed via ANCOVA, examining between group differences at follow-up, controlling for baseline values. Response times on the complex Stroop test were faster at follow-up in the intervention group (Intervention: 1357 ms [1280–1400 ms]; Control: 1463 ms, [1410–1523 ms], d = 0.31, p = 0.048). There was no effect of The Daily Mile on the Sternberg paradigm or Flanker test. Physical fitness was greater at follow-up in the intervention group (Intervention: 880 m, [820–940 m]; Control: 740 m, [680–800 m], d = 0.39, p = 0.002). There was no effect of the intervention on adiposity. In conclusion, five-weeks of The Daily Mile enhanced inhibitory control and physical fitness in children, but did not affect working memory, attention, or adiposity.
