Key Highlights

• A cross-sectional study of 713 Chinese preschoolers (ages 3–6) found motor coordination and physical fitness each correlate with better executive functions; physical fitness partially or fully mediates the link between motor coordination and cognition.
• Physical fitness (measured by six standardized tests) acted as a complete mediator for working memory (accounting for 46.9% of the total effect) and as a partial mediator for cognitive flexibility (28.7%) and inhibitory control (31.5%).
• Interventions that combine coordinative skill practice with aerobic and strength-related fitness work—delivered as integrated, play-based activities—are the most likely to yield measurable gains in early executive function.

Introduction

Preschool years shape the neural and behavioral building blocks that sustain lifelong learning. Motor coordination and physical fitness develop rapidly between ages three and six, a period when executive functions—cognitive flexibility, inhibitory control, and working memory—also expand. Recent research that assessed 713 preschool children provides robust empirical evidence of how movement and fitness relate to cognitive performance and reveals a specific developmental pathway: motor coordination supports physical fitness, which in turn supports executive function. That pathway carries practical implications for early education, family routines, and public-health strategies aimed at optimizing children’s cognitive and motor development simultaneously.

This article synthesizes the study’s methods and findings, situates them within current knowledge about brain and behavioral development, and translates results into concrete recommendations for educators, clinicians, and parents who want to strengthen children’s cognitive readiness through movement-based programming.

Why the 3–6 age window matters for movement and cognition

Between ages three and six the brain’s structural and functional networks undergo intensive organization. Motor circuits that coordinate perception, planning, and execution—anchored in regions such as the cerebellum, basal ganglia, and sensorimotor cortex—refine their connectivity. Prefrontal systems that subserve executive functions also mature, creating a period of heightened neuroplasticity. Movement experiences do not merely shape motor skill; they shape the neural context in which cognitive control processes operate.

Two conceptually distinct but complementary constructs matter here:

• Motor coordination refers to the quality of sensorimotor integration, balance, manual dexterity, and timed targeting. Measures like the Movement Assessment Battery for Children–Second Edition (MABC‑2) capture this domain across tasks such as bead threading, catching, and static/dynamic balance.
• Physical fitness is a broader, systemic construct reflecting cardiorespiratory endurance, muscular strength/endurance, and flexibility. For preschoolers, tests such as standing long jump, shuttle runs, sit-and-reach, and ball throws produce an index of fitness that reflects both the child’s habitual activity and physiological capacity.

The study confirms that these domains advance together but also contribute uniquely to cognition: coordination provides the behavioral scaffolding for complex actions; fitness supplies the metabolic and circulatory support that allows sustained neural processing.

How the study measured movement, fitness and executive function

The study recruited 713 children from a kindergarten in Weifang City, Shandong Province, China, and assessed them with validated tools under standardized procedures. Key elements of the protocol:

• Motor coordination: MABC‑2 (age band 3–6). The MABC‑2 yields standardized sub-scores for manual dexterity, aiming & catching, and balance, combined into a composite motor coordination standard score. Testing took 30–40 minutes per child and used age- and gender-adjusted scoring.
• Physical fitness index (PFI): Based on the Chinese National Physical Fitness Measurement Standards Manual for Preschool Children. Six field tests were administered—standing long jump, tennis ball throw, 10-meter shuttle run, 15-meter obstacle run, sit-and-reach, and walking on a balance beam. Scores were standardized within age and gender to create a composite z-score index.
• Executive function battery: Three validated behavioral tasks measured the core components:
  • Cognitive flexibility: an iPad-based card sorting task adapted from the Dimensional Change Card Sort with switching rules; performance scored as correct responses after the rule switch.
  • Inhibitory control: Day/Night Stroop-like paradigm, combining “day/night” and “happy/sad” conditions; total correct responses across trials formed the score.
  • Working memory: a Self-Ordered Pointing Task adapted for preschoolers that assessed visual-spatial working memory span across increasingly difficult trials.

Testing was conducted one-on-one by trained examiners in quiet rooms. Cognitive tasks were administered first, followed by motor and fitness assessments; sessions were spread across two days per child to limit fatigue.

Statistical approach: Pearson correlations to establish bivariate relations, hierarchical regressions controlling for age, gender, and BMI to evaluate independent contributions of motor coordination and fitness to cognitive outcomes, and bootstrap mediation analysis (PROCESS Model 4, 5,000 resamples) to quantify whether fitness mediated motor coordination’s effect on cognition.

What the data reveal: associations and independent effects

A clear pattern emerged when researchers examined correlations and predictive models.

Correlations

• Motor coordination correlated moderately with physical fitness (r = 0.443, p < 0.01).
• Motor coordination correlated positively with all cognitive measures:
  • Cognitive flexibility: r = 0.250
  • Inhibitory control: r = 0.228
  • Working memory: r = 0.145
• Physical fitness also correlated positively with the three executive functions, with coefficients ranging from r = 0.189 to r = 0.241.
• The three cognitive measures were themselves positively intercorrelated (rs ≈ 0.20–0.24), consistent with the partially overlapping but distinct nature of executive function components in preschoolers.

Independent predictive effects (hierarchical regression controlling for age, gender, BMI)

• Cognitive flexibility: Both motor coordination (β = 0.141, p = 0.001) and physical fitness (β = 0.106, p = 0.015) were independent positive predictors. Age also predicted flexibility (β = 0.155, p = 0.001).
• Inhibitory control: Motor coordination (β = 0.120, p = 0.003) and physical fitness (β = 0.098, p = 0.025) predicted inhibitory control independently. Age again was a positive predictor (β = 0.163, p < 0.001).
• Working memory: Physical fitness predicted working memory (β = 0.093, p = 0.035), while motor coordination did not have an independent effect (β = 0.035, p = 0.404). Age remained the strongest predictor (β = 0.176, p < 0.001).

Interpretation of these patterns

• Both motor coordination and fitness contribute to the development of cognitive flexibility and inhibitory control, suggesting separate pathways of influence: coordinated movement practice supports neural systems for planning and set‑shifting, while fitness improves sustained physiological support for cognitive processing.
• Working memory appears to rely more directly on physiological resources captured by the fitness index. Motor coordination contributes indirectly by supporting the activities and movement patterns that enable children to accumulate aerobic and muscular fitness.

The mediation pathway: physical fitness as the bridge

Mediation analyses quantified the extent to which physical fitness explains the association between motor coordination and executive functions.

Key mediation findings (bootstrap, 5,000 resamples)

• Cognitive flexibility: Total effect of motor coordination on flexibility = 0.296 (95% CI [0.212, 0.380]). Indirect effect via physical fitness = 0.085 (95% CI [0.045, 0.127]), representing 28.7% of the total effect. Direct effect remained significant, indicating partial mediation.
• Inhibitory control: Total effect = 0.251 (95% CI [0.172, 0.330]). Indirect effect via fitness = 0.079 (95% CI [0.041, 0.119]), representing 31.5% of the total effect. Again partial mediation.
• Working memory: Total effect = 0.098 (95% CI [0.048, 0.147]). Indirect effect = 0.046 (95% CI [0.020, 0.073]), accounting for 46.9% of the total effect. The direct effect of motor coordination on working memory was non-significant, indicating full mediation by physical fitness.

What this means for developmental sequencing

• Motor coordination and fitness form an “ability chain” during early childhood. Good coordination leads to successful participation in active play and structured movement, increasing opportunities for moderate-to-vigorous activity that bolster cardiorespiratory and muscular fitness. The physiological changes associated with improved fitness—enhanced cerebral blood flow, favorable neurotrophic factor expression, and optimized metabolic support—create conditions that enable higher cognitive performance, particularly for working memory.
• For processes like cognitive flexibility and inhibitory control, the relationship is more complex: coordination contributes directly to the cognitive skills required for planning and response selection, while fitness amplifies and supports these processes.

Practical implications: how to design activities that build skills and cognition

The study’s findings translate directly into actionable guidance for programs, teachers, and families who want to use movement to support early cognitive development.

Design principles for effective preschool movement programs

1. Integrate coordinative challenges with aerobic load:
   • Combine tasks that require balance, hand-eye coordination, and sequencing (e.g., beanbag tosses to targets, hopping sequences, obstacle courses) with activities that increase heart rate (short bursts of running, shuttle runs, active games).
   • Example session: a 20–30 minute circuit composed of 6 stations—balance beam walk (balance), target throw (aiming & catching), ladder hops (rhythm & coordination), short shuttle run (aerobic), sit-and-reach/stretch station (flexibility), and a gamified memory-movement task (cognitive challenge paired with movement).
2. Make tasks progressively challenging and variable:
   • Adapt constraints—space, task speed, object size, or cognitive rule—to keep novelty and demand within a child’s zone of proximal development.
   • Gradual increases in complexity produce both motor learning and cognitive engagement (rule switching, inhibition tasks).
3. Use game formats to increase engagement and intensity:
   • Tag variants, relay races with rules that change mid-game (requiring rule-switching and inhibition), and obstacle courses timed in small teams produce aerobic stimuli while encouraging coordination and executive control.
4. Embed cognitive demands explicitly:
   • Add rules that require children to remember a sequence, inhibit a prepotent response, or switch sorting criteria (e.g., “If I clap, sort by color; if I stomp, sort by shape”) during movement.
   • Pairing cognitive tasks with movement leverages embodied cognition: children practice the very executive skills measured in the lab while moving.
5. Ensure sufficient dose and frequency:
   • While precise dose-response relationships for preschoolers remain under study, practical programs should aim for multiple short sessions per day (two 15–20 minute sessions) or daily 30+ minute blocks of structured movement across the week.

Real-world program examples and adaptations

• Kindergarten class routine: Replace one sedentary storytime per day with an active story session that asks children to act out verbs, change rules based on story cues, and perform simple physical sequences—this boosts both coordination and cognitive engagement.
• Home activities for parents: Family obstacle courses in the living room or backyard that incorporate throwing, balancing on a line, and direction-switching can be completed in 15–20 minutes and require minimal equipment.
• Clinical/therapeutic settings: For children identified with delayed motor coordination, therapists should include aerobic components in addition to task-specific motor training to strengthen the fitness-mediated pathway to cognition.

Teacher training and implementation tips

• Train teachers to scaffold difficulty, observe individual variability, and measure progress with simple, classroom-friendly checklists (e.g., number of successful balance trials, time to complete a shuttle run, accuracy in rule-switch tasks).
• Provide lesson plans that outline progression across weeks and incorporate simple fidelity checks.
• Use play-based assessment during routine activities to identify children who may need additional screening for motor coordination or fitness deficits.

Implications for assessment, screening and targeted support

Screening approaches

• Combine a quick coordination screen (e.g., timed balance holds, simple ball catch tasks) with a brief fitness proxy (timed 10–20 m run or standing long jump) to flag children needing further evaluation.
• Children with low coordination and low fitness scores should be prioritized for integrated intervention because they stand to benefit from both skill-specific training and aerobic conditioning.

When to refer for specialist assessment

• If classroom-based interventions over several months yield limited improvement in coordination or if motor difficulties affect safety, daily participation, or learning, refer to pediatric physical therapy or developmental assessment.
• Persistent difficulties in inhibitory control and working memory, coupled with motor delays, may warrant evaluation for developmental coordination disorder (DCD) or other neurodevelopmental conditions.

Measuring outcomes

• Pre- and post-intervention assessment should include both motor and cognitive measures. For feasibility:
  • Motor coordination: MABC‑2 or shorter validated screening subsets.
  • Fitness: standing long jump, shuttle run time; convert to age- and gender-standardized scores.
  • Cognition: simple card‑sort switching tasks and Day/Night inhibitory tasks administered in classrooms or quiet testing rooms.

Policy and curriculum considerations

Preschool curriculum planners and public-health officials can use these results to justify integrated movement policies.

Curriculum integration

• Preschools should allocate daily time for structured, skillful movement, not merely free play. Scheduled movement blocks that intentionally target balance, coordination, and aerobic work will promote both physical and cognitive outcomes.
• Move beyond token PE: professional development for teachers should emphasize how to embed cognitive demands into movement tasks.

Public health and equity

• Children from low-resource settings often have fewer safe spaces and organized opportunities for moderate-to-vigorous play. Policy investments in safe playgrounds, equipment-lending programs, and training for community childcare providers would reduce disparities.
• Screen-and-support models at municipal or district levels can identify preschools with lower average motor/fitness profiles and deploy targeted teacher-training and equipment packages.

Parental guidance and community programming

• Parent workshops should focus on accessible activities that families can do at home—obstacle courses, ball games, dance sessions—that provide both coordination challenges and aerobic stimulus.
• Libraries and community centers can host “movement storytimes” or short play-based movement classes for toddlers and preschoolers, expanding access.

Neurophysiological mechanisms: how movement may change the brain

Mechanistic explanations in the literature converge on several plausible biological pathways:

• Cerebral perfusion and oxygenation: Aerobic activity increases cerebral blood flow and oxygen delivery, which supports neural processing required for demanding cognitive tasks.
• Neurotrophic factors: Physical activity upregulates factors like brain-derived neurotrophic factor (BDNF), which support synaptic plasticity and learning.
• Network efficiency and connectivity: Coordinated movement practice may strengthen sensorimotor-prefrontal loops, improving the brain’s capacity to coordinate perception, action, and cognitive control.
• Resource allocation and metabolic capacity: Fitness improves systemic energy delivery and metabolic efficiency, enabling sustained engagement with tasks that tax working memory.

The study did not directly measure neurophysiological indices (EEG, fNIRS, BDNF), so mechanistic inferences remain theoretical. Future studies linking behavioral measures to neural markers would clarify causal pathways.

Limitations and caveats in applying the findings

The research provides robust cross-sectional evidence but carries constraints that affect how the results should be interpreted and applied:

• Cross-sectional design: Associations do not prove causation. While mediation models suggest a pathway from motor coordination through fitness to cognition, longitudinal or randomized controlled trials are required to demonstrate causal direction.
• Single-site sampling: Participants came from a single kindergarten in one Chinese city; cultural, socioeconomic, and environmental factors may modulate generalizability.
• Behavioral-only cognitive measures: Lab-based tasks capture key executive functions but lack direct neurophysiological validation. Subtle cognitive processes might be missed.
• Conceptual overlap: Some fitness items (e.g., balance beam) and coordination tasks share motor demands, creating residual measurement overlap despite sensitivity analyses.
• Multiple statistical comparisons and thresholds: The study reported p-values and effect sizes; some p-values for fitness predictors were modest (e.g., p = 0.025 and p = 0.035). Interpret effects alongside effect sizes (betas) and confidence intervals rather than relying solely on p-values.

These caveats underscore the need for cautious translation: integrated movement programming is sensible and low-risk, but claims about precise effect sizes and timelines for cognitive change should await longitudinal and intervention research.

Directions for research and evaluation

Priority next steps for the field:

• Randomized controlled trials that compare:
  • Coordinative-only training,
  • Aerobic/fitness-only training,
  • Integrated coordinative-plus-fitness training, with active controls to isolate effects on executive functions and academic precursors.
• Longitudinal cohorts tracking children across preschool into early school years to examine persistence of effects and sensitive periods for intervention.
• Multimodal measurement: combine behavioral testing with EEG, fNIRS, or blood biomarkers (e.g., BDNF) to directly observe neural changes tied to movement interventions.
• Dose–response studies: identify minimal-effective duration, frequency, and intensity for cognitive benefits in preschoolers.
• Implementation science: evaluate how teacher training, resources, and curriculum constraints influence fidelity and outcomes at scale.

Practical toolkit: sample activities and program templates

Below are example activities and a sample weekly structure educators or parents can adapt immediately.

Sample activity ideas

• Rule-Switch Relay: Children run to a station and perform an action (hop, skip, balance) based on an initial rule (e.g., red = hop). Halfway through the relay the rule swaps (red = skip), requiring cognitive flexibility and motor adjustment.
• Memory-Action Sequence: Place 4–6 picture cards; the teacher names a sequence and children must perform the sequence of actions corresponding to the pictures. This adds working-memory demands to movement.
• Balance-and-Throw Circuit: Balance beam walk to a target, then throw a ball into a hoop; adjust ball size and hoop distance to scale difficulty.
• Freeze-and-Think Game: Play music and have children move; when music stops, call a category (animals, colors). Children must freeze in a pose that matches the category—a test of inhibition and representational flexibility.

Sample week (for a kindergarten class)

• Monday: 30-minute morning movement block focusing on balance and coordination (stations).
• Tuesday: 20-minute high-intensity play session (short runs, tag games) with a 10-minute cognitive rule-switch activity.
• Wednesday: 30-minute integrated circuit combining movement sequences with memory tasks.
• Thursday: Active storytime—movement acting with interruptions requiring inhibition (stop/go).
• Friday: Game-based assessment: short battery of movement tasks and rule-switch tests to monitor progress.

Equipment list (low-cost)

• Cones, hoops, beanbags, soft balls, low beams (tape line on floor), ladders or taped patterns, stopwatches, laminated picture cards.

Monitoring progress

• Simple checks: record number of successful balance trials, shuttle run times, and accuracy on a short card‑sort task every 4–6 weeks.
• Use group-averaged improvements to adapt session difficulty and frequency.

FAQ

Q: How do motor coordination and physical fitness differ, and why both matter? A: Motor coordination describes the precision and control of movements—how well a child integrates sensory input and plans/exe­­cutes actions (balance, catching, manual dexterity). Physical fitness captures systemic capacities—cardiorespiratory endurance, muscular strength, flexibility. Coordination enables participation in active play and practice; fitness supplies the metabolic and circulatory support needed for sustained cognitive processing. Both relate to executive functions through complementary pathways.

Q: Which executive functions are most influenced by movement and fitness? A: Cognitive flexibility and inhibitory control show independent associations with both motor coordination and fitness. Working memory demonstrates stronger dependence on fitness: in this study, physical fitness mediated nearly half of motor coordination’s total effect on working memory.

Q: How quickly can parents or teachers expect cognitive benefits from integrated movement programs? A: The evidence base does not yet define precise timelines. Short-term improvements in motor skill and fitness can appear within weeks to months; cognitive changes—especially those tied to working memory—may require consistent practice and sufficient aerobic load over months. Regular, integrated sessions several times per week are more likely to produce measurable gains.

Q: Are there risks to introducing more movement in preschool schedules? A: Properly designed movement activities are low-risk. The primary considerations are safety (age‑appropriate equipment and supervision), adequate warm-up, and tailoring difficulty to the child. Movement also yields non-cognitive benefits—social skills, emotional regulation, and physical health.

Q: Should screenings be conducted at preschool entry? A: Brief screening for motor coordination and basic fitness markers can identify children who may need additional support. Tools like a short MABC‑2 subset or teacher-administered coordination tasks combined with simple fitness checks (standing long jump, timed runs) can be informative.

Q: What about children with motor coordination disorders (DCD)? A: Children with suspected DCD may require individualized therapy with a pediatric physical therapist. Programs that integrate aerobic conditioning alongside motor skill training may produce broader cognitive and health benefits. Early referral and coordinated multidisciplinary care are recommended.

Q: Do these findings apply across different cultural or socioeconomic settings? A: The data come from a single geographic sample and require replication in diverse settings. The underlying developmental principles are likely generalizable, but resource constraints, play opportunities, and cultural practices will shape optimal program design and access.

Q: What research would make the evidence stronger? A: Randomized controlled trials comparing different types of movement interventions, longitudinal cohorts following developmental trajectories, and multimodal studies linking behavioral outcomes to neurophysiological measures (EEG, fNIRS, biomarkers) would strengthen causal inference and clarify mechanisms.

Q: How can policymakers use this evidence? A: Policymakers can support mandatory daily movement time in preschool curricula, fund teacher training in integrated movement pedagogy, and invest in safe play infrastructure in underserved communities. Screening and targeted support programs can reduce disparities in developmental opportunity.

Q: If a preschool can only add one thing, what should it add? A: Add an integrated, structured 20–30 minute movement session daily that combines coordinative challenges (balance, catching, sequencing) with short bouts of aerobic play. This single change produces multi-domain benefits and is feasible within constrained schedules.
