Objective: This study aims to clarify the governmentʼs dissemination measures for implementing the early childhood exercise program (hereafter, “exercise program”).

Methods: We evaluated the implementation process of exercise programs for childcare workers in Unnan City using the PAIREM model. Our evaluation utilized government, childcare facility, and preschool worker data from 2016 to 2021. We analyzed the fundamental movement skills of preschoolers up to 2019, considering the impact of the coronavirus disease 2019 pandemic on the data.

Results: Plan: The goal was to determine “the percentage (95.0%) of parents who perceive their child as being physically and mentally healthy.ʼʼ The government planned “the number of workshops held,ʼʼ including “the number of kindergartens and children who would participate in fundamental movement skills tests.ʼʼ There was no target value for fundamental movement skills improvement in preschoolers. Implementation: The educational administration held 14 training sessions for childcare providers over six years. Reach: Study materials were distributed to all childcare providers. A total of 21 pseudo-childcare facilities and 18.5% (342/1849) of pseudo-childcare workers were included in the training sessions. Effectiveness: The percentage of pseudo-childcare workersʼ exercise support behavior for preschoolers ranged from 75.5% to 90.4%. Furthermore, fundamental movement skills measurements showed that the softball throw and 25-meter run were higher in 2019 compared to 2016 for children aged 4–5 years. However, the standing long jump in 2019 was lower than in 2016 among children aged 5 years. Maintenance: Data will be collected in the future.

Conclusion: The evaluation by PAIREM clarified the governmentʼs implementation of measures to disseminate exercise programs through workshops, among others. Further improvements and promotion of the project will be necessary in the future.

Purpose: The protocol on graduated return to play (GRTP) after concussion was revised in August 2022 for Japanese rugby. This study aimed to investigate the occurrence of injures, including concussion, in male college rugby players and to compare the frequency of these incidents before and after the revision of the GRTP protocol following a concussion.

Methods: This study adopted epidemiological observational research design. We recorded the total number of injuries including concussions, the number of days until return to play after a concussion, and the recurrent concussions among 101 male collegiate rugby players of one team before (September to December 2021) and after (September to December 2022) the revision of GRTP protocol. We calculated the exposure time in rugby matches and trainings, the incidence rate per 1000 hours (injuries/1000 h), the 95% confidence interval (95% CI), and the rate ratio.

Results: During the study period, 146 injuries occurred. The incidence of all injures was signifi cantly lower after the GRTP revision (6.2 injuries/1000 h; 95% CI, 4.7-7.6) than before the GRTP revision (8.9 injuries/1000 h; 95% CI, 6.9-10.9)(Rate Ratio=0.67; 95% CI, 0.48-0.92). The incidence of concussion was also significantly lower after the GRTP revision (0.7 concussions/1000 h; 95% CI, 0.2-1.2) in comparison to before the revision (1.7 concussions/1000 h; 95% CI, 0.8-2.6)(Rate Ratio=0.41; 95% CI, 0.18-0.92). The rate of recurrent concussions dropped from 18.7% before the GRTP protocol revision to 0% following the protocolʼs revision.

Conclusions: We investigated the incidence of all injuries among male collegiate rugby players before and after the revision of the staged GRTP protocol following a concussion and observed a decrease in the incidence of both injuries and concussions following the revision.

Objective: Physical inactivity among children and adolescents with disabilities might increase the risk of serious health problems. The purpose of this study was to summarize an overview of international trends in the evaluation methodology of physical activity for children and adolescents with disabilities.

Methods: Literatures from 14 countries or jurisdictions that participated in “Global Matrix of Para Report Cards on Physical Activity of Children and Adolescents With Disabilities” were identified. Evidence to grade the overall physical activity levels in each country or jurisdiction was collected to summarize the evaluation methodology of physical activity for children and adolescents with disabilities.

Results: The Health Behaviour in School-aged Children (HBSC) questionnaire was used most frequently among the 11 countries or jurisdictions (5 countries, 45.5%). Many countries used questionnaires, including the HBSC questionnaire, that ask participants about “the number of days in which they achieved 60 minutes/day of moderate to vigorous physical activity” to evaluate their physical activity (8 countries or jurisdictions: 72.7%). Three countries and 1 jurisdiction (36.4%) assigned their grade of overall physical activity using both questionnaire and accelerometer.

Conclusion: The present study showed that the frequency of achieving 60 minutes/day of moderate to vigorous physical activity using a question or questionnaire (e.g., HBSC) was the most frequently used to evaluate the overall physical activity in children and adolescents with disabilities among 11 countries or jurisdictions.
