2 Outline Development of gross motor skills / fundamental movement skills in early childhood highly relevant for school sport, talent id, and youth development Gross motor skills What are they? Why are they important? How are they developed? How are they measured? Factors associated with gross motor development Take home messages

3 What are gross motor skills? Object control skills hit, kick, bounce, roll, throw and catch an object Locomotor skills run, gallop, hop, leap, jump, slide Balance static and dynamic Strength trunk, upper and low body Coordination Influenced by core strength, awareness of the two sides of the body, and crossing the midline

4 Why are they important for young children?

5 The physical activity perspective More emphasis on measuring physical activity Less focus on how learning to move is a necessary skill underlying physical activity Gross motor skills form the foundation for future movement and physical activity The base camp from which children climb the mountain of motor development to achieve context-specific motor skills Children follow different trajectories, depending on individual constraints and environmental opportunities Stodden DF, Goodway JD, Langendorfer SJ, Robertson MA, Rudisill ME, Garcia C, et al. A developmental perspective on the role of motor skill competence in physical activity: an emergent relationship. Quest. 2008;60:

6 The physical activity perspective Physical activity in early childhood drives the development of gross motor competence Increased physical activity provides more opportunities to promote neuromotor development, which promotes the development of gross motor skills Stodden DF, Goodway JD, Langendorfer SJ, Robertson MA, Rudisill ME, Garcia C, et al. A developmental perspective on the role of motor skill competence in physical activity: an emergent relationship. Quest. 2008;60:

7 The sport / athletic perspective Youth Physical Development Model Builds on Long-term Athlete Development Model Critical windows of opportunity when children are more sensitive to training-induced adaption Failure to use these windows will result in limitation of future athletic potential Criticised for being too theoretical and not substantiated by longitudinal empirical evidence But sensitive periods / windows of opportunity are not unfamiliar terms in child development Lloyd RS, Oliver JL, Faigenbaum AD, Howard R, De Ste Croix MBA, Williams CA, et al. Long-term athletic developmentpart 1: a pathway for all youth. J Strength Cond Res May;29(5):

8 The sport / athletic perspective Fundamental movement skill development helps to ensure that children master the right movement patterns in a safe and fun environment to enable them to carry out more complex sports movements later in childhood and adolescence Fundamental movement skills = building blocks for sportspecific movement patterns Physical development programmes in early childhood should focus on the development of fundamental movement skills Lloyd RS, Oliver JL, Faigenbaum AD, Howard R, De Ste Croix MBA, Williams CA, et al. Long-term athletic developmentpart 1: a pathway for all youth. J Strength Cond Res May;29(5):

9 The sport / athletic perspective Physical qualities Fundamental movement skills Strength Mobility, agility, speed, power Sport-specific skills, endurance and metabolic conditioning Hypertrophy Training should be unstructured Lloyd RS, Oliver JL, Faigenbaum AD, Howard R, De Ste Croix MBA, Williams CA, et al.

10 A developmental perspective Early sensorimotor experiences form the foundation for the development of higher order cognitive processing skills Opportunities to explore the environment (developing understanding of oneself in space and in relation to other objects) and later to manipulate objects (developing understanding of relationships between them) are especially important in development Relates to the concept of learning through play and physical activity Sigelman C, Rider E. (2003). Lifespan human development (4th ed.). Belmont, CA: Wadsworth.

11 Developing gross motor skills Misconception that children naturally learn them Many children are not proficient, e.g. in low-income US settings Context of physical activity / gross motor development in early childhood should be fun and enjoyable, non-competitive, and inclusive Differences in experience lead to different levels of competency E.g. environment, SES, structured activities, parental influences, climate Constraints can compound in later childhood Stodden DF, Goodway JD, Langendorfer SJ, Robertson MA, Rudisill ME, Garcia C, et al. A developmental perspective on the role of motor skill competence in physical activity: an emergent relationship. Quest. 2008;60:

12 What about free play?

13 GMS levels in SA low-income settings Low-income rural (Agincourt, MP) 17% superior 28% above average 46% average 9% below average & poor Low-income urban (Masiphumelele, Cape Town) 3% superior 20% above average 72% average 5% below average & poor But what about compounding constraints?

14 Measuring gross motor skills Bruininks-Oseretsky Test of Motor Proficiency Gold standard? Gross motor skills assessed: Upper limb coordination Bilateral coordination Balance Running speed and agility Strength Score number of correctly executed skills / time taken Used in clinical research Complete: minutes (incl. fine motor skills) Short: minutes

15 Measuring gross motor skills Movement Assessment Battery for Children Designed to assist professionals helping children with movement difficulties Manual dexterity Aiming and catching a beanbag Static and dynamic balance Score number of correctly executed skills qualitative observations per skill Standard score (for each age group) classifies child as normal, at risk, or having definite motor impairment minutes per child, depending on age

16 Measuring gross motor skills Test of Gross Motor Development Object control: hit, kick, bounce, roll, throw and catch ball Locomotor: run, gallop, hop, leap, jump, slide Assessed according to observed and scored performance criteria (±4 per skill) on how skill is executed Can be video recorded and scored later Frequently used in research Used in South African studies of preschool children minutes for group of 5 children

17 What would work in your setting? Time available Human resources Ceiling effects? Leave room for improvement Why are you testing? Picking up developmental delays Establishing levels of proficiency Documenting changes over time

18 Factors associated with gross motor skill development

19 Physical activity Increased physical activity has been associated with greater gross motor competence Cause and effect not yet demonstrated Do those who are more active develop skills more easily (especially structured physical activities for children)? OR Do those who have better skills (or higher perceptions of their skills) participate in more activity? Childhood gross motor proficiency is predictive of physical activity in adolescence Holfelder B, Schott N.

20 Fitness Greater gross motor competence associated with higher levels of fitness, incl. cardiorespiratory and musculoskeletal fitness (boys and girls) Preschool gross motor scores shown to be strongly predictive of all fitness measures in adolescence 1.5m run, sit-up, sit-and-reach, body fat % Object control skills more predictive of overall physical fitness than locomotor skills (boys and girls) Locomotor skills may be developed as a by-product of object control skill development Cattuzzo MT, et al.

22 Overweight and obesity Higher levels of physical activity associated with healthier body weight in early childhood Poor gross motor skills have been associated with overweight and obesity in childhood, including in early childhood Overweight and obese children tend to struggle with assessments of relative or functional strength (what they can do with their body, e.g. push-up) More relevant to their mobility and quality of life Cattuzzo MT, et al.

23 Executive function Mental processes are required when you need to pay attention and concentrate Inhibition: inhibitory control, including self-control and interference control Working memory: working with info kept in mind Cognitive flexibility: ability to shift between tasks, related to creativity Attention Predicts Lifelong achievement, health, wealth and quality of life Academic achievement and school readiness Diamond A.

24 Executive function Why is executive function relevant here? Positively associated with physical activity Negatively affected by poor physical fitness Structured activities that are cognitively engaging can improve executive function Tasks requiring gross motor movement also been shown to predict better math and emerging literacy scores Sport participation that involves social skills that promote complex, higher-level cognitive skills may be the most beneficial for executive function Best JR.

25 Perceptions of motor competence Younger children have limited capacity for perceiving their levels of competency, ability and effort Tend to overestimate their abilities More relevant in older children BUT: young children may keep trying to master skills that they believe they are good at, and hence foster proficiency in these skills If young children are already beginning to make selfjudgments, we should encourage opportunities to help them feel and become physically competent Stodden DF, Goodway JD, Langendorfer SJ, Robertson MA, Rudisill ME, Garcia C, et al.

26 Take home messages Whatever your perspective, early childhood is a crucial time for gross motor development The context of this development is important young children should PLAY Provide and promote opportunities for structured and unstructured activity Use the right building blocks to build a good foundation Allow for exploration and learning through play Assess GMS from early on to identify areas of strength to build on, and areas of weakness to strengthen
