Super Quinas Preschool Intervention, 80 Children, Maia Portugal
ClinicalTrials.gov Studies
Summary
This is the clinical trial registration for NCT07553507, a quasi-experimental controlled study evaluating the 'Super Quinas in Preschool' programme on 24-hour movement behaviours and motor development in preschool children aged 3-6 years. The 12-week intervention consists of one structured 60-minute physical activity session per week, delivered by a qualified exercise professional in a public preschool in Maia, Portugal, with approximately 80 children across four classes. Baseline data collection occurred February-March 2026, with subsequent assessments planned through September 2026.

About this source
ClinicalTrials.gov is the NIH-run registry of every clinical trial conducted in the United States, plus most international trials sponsored by US-based companies or institutions. By federal law, sponsors must register Phase 2 through Phase 4 studies before enrolling patients and post results within a year of completion. This feed tracks every new trial registration and study update, around 700 a month: drug interventions, device studies, behavioral protocols, observational research. Watch this if you scout drug candidates moving into mid or late-stage development, monitor competitor pipelines, or follow rare disease research where new trials signal patient hope. GovPing parses sponsor, phase, intervention, and target indication on each entry.
What changed
This NCT07553507 clinical trial registration describes a new quasi-experimental controlled study conducted at a public preschool in Maia, Portugal. The 'Super Quinas in Preschool' programme delivers one additional structured 60-minute physical activity session per week for 12 weeks, delivered by a qualified exercise professional. Approximately 80 children across four classes are allocated at the class level: two intervention classes and two control classes receiving usual Physical Education. Primary outcomes are 24-hour movement behaviours measured by accelerometry, motor competence, and physical fitness. Secondary outcomes include executive function and socioemotional regulation.
For institutions conducting or reviewing similar school-based physical activity research, this registration provides methodological reference for quasi-experimental controlled study designs in early childhood settings. Researchers should note the longitudinal assessment framework with four timepoints (baseline, mid-intervention, post-intervention, and follow-up) and the use of validated instruments including ActiGraph GT3X accelerometry, Motor Competence Assessment, PREFIT subtests, HTKS, Day-Night Stroop, and SDQ.

Effects of a School-Based Physical Activity Intervention on 24-Hour Movement Behaviours and Motor Development in Preschool Children - Study Protocol
N/A NCT07553507 Kind: NA Apr 28, 2026
Abstract
This protocol describes a quasi-experimental controlled study evaluating the effects of the Super Quinas in Preschool programme on 24-hour movement behaviours and motor development in preschool children aged 3-6 years. The intervention consists of one additional structured 60-minute physical activity session per week for 12 weeks, delivered by a qualified exercise professional in a public preschool in Maia, Portugal. Four classes (~80 children) are allocated at the class level: two to the intervention condition and two to the control condition (usual curricular Physical Education). Baseline data collection (T0) was conducted between 23 February and 16 March 2026; the intervention commenced on 25 March 2026. Subsequent assessments are planned for early May (T1, mid-intervention), end of June (T2, post-intervention), and mid-September 2026 (T3, follow-up). Primary outcomes are 24-hour movement behaviours (ActiGraph GT3X accelerometry) and motor competence and physical fitness (Motor Competence Assessment + PREFIT subtests). Secondary outcomes include executive function (HTKS; Day-Night Stroop) and socioemotional regulation (SDQ). Statistical analyses will use longitudinal linear mixed-effects models under an intention-to-treat framework.
