Physical Activity and Children: Building a Lifelong Love of Movement

Physical Activity: Essential for Child Development

Regular physical activity is one of the most important contributors to children�s physical and mental health. The evidence is extensive and consistent: children who are regularly physically active have better cardiovascular health, stronger bones and muscles, healthier weight profiles, better sleep, improved concentration and academic performance, lower rates of anxiety and depression, and stronger social skills. These benefits are not minor or marginal: physical activity is one of the most potent health behaviours available to children and families.

Despite this, levels of physical activity among children in many high-income countries have declined significantly over recent decades, with screen time and sedentary behaviour replacing what were once more active childhoods. Understanding what children need, and how to support it in modern life, helps families build the active habits that will benefit children throughout their lives.

How Much Physical Activity Do Children Need?

Most major health organisations recommend the following:

• Under 5: Active play for at least three hours spread throughout the day, including some vigorous play. Minimise time spent in car seats, pushchairs, or high chairs beyond transport and sleep.
• Ages 5 to 17: At least 60 minutes of moderate to vigorous physical activity every day. This does not need to be achieved in a single session and can be accumulated through multiple activities across the day. At least three days per week should include vigorous activity that makes children breathe hard and strengthens muscles and bones.

For most children, this is achievable without structured sport: walking, cycling, active play in the garden or park, and physical education at school all contribute. The target is activity across the day, not necessarily an hour of dedicated exercise.

Movement in the Early Years

Physical activity habits established in early childhood are more likely to persist through adolescence and into adulthood than those introduced later. Creating an active lifestyle from infancy is far easier than changing established sedentary habits in older children.

For babies and toddlers, tummy time, rolling, crawling, climbing, and active play are the foundations of physical development. The outdoor environment is particularly valuable: natural environments invite movement, exploration, and sensory engagement in ways that indoor environments often do not. Even short, regular outdoor experiences in rain, mud, and cold weather develop physical confidence and tolerance of physical discomfort that indoor environments cannot replicate.

Supporting Active Habits in School-Age Children

School-age children who have enjoyable experiences of physical activity are more likely to remain active than those for whom sport and exercise are primarily associated with failure, embarrassment, or obligation. Helping children find the types of movement they genuinely enjoy, and supporting that enjoyment, is more productive in the long term than pushing them toward activities that are valued by others but not by them.

Active travel, walking or cycling to school, social activities, and unstructured outdoor play all contribute to daily activity goals without the structure and potential pressure of organised sport. Many children accumulate more genuinely enjoyable activity through free play and active transport than through organised sport, and this informal activity is equally valuable for health.

Managing Screen Time Competition

The primary competition for children�s physical activity time in modern households is screens. Research on physical activity and screen time consistently shows that they are inversely related: children with higher screen time tend to be less active, and children with more active lifestyles tend to have lower screen time. Reducing screen time, particularly during times when children would otherwise be active, is one of the most effective ways to increase physical activity.

Rather than simply reducing screens, replacing screen time with active alternatives reduces conflict and provides positive motivation. Planning specific active alternatives and making them genuinely appealing, through shared family participation, outdoor environments, and social opportunities, is more effective than simply removing screens without replacement.

Supporting Reluctant Movers

Some children are naturally more sedentary than others and may actively resist or show little interest in physical activity. Reasons vary: some children have undiagnosed developmental coordination difficulties that make physical activity less rewarding, some have had negative experiences of sport or physical education, and some simply prefer sedentary pursuits.

Avoid force or pressure, which consistently reduces long-term physical activity engagement. Instead, find the specific type of movement that appeals to the individual child: some children who resist traditional sport enjoy dance, martial arts, swimming, or cycling. Non-competitive activities, individual rather than team activities, or activities linked to a strong interest may provide the entry point for a reluctant mover to develop genuine engagement with physical activity.

If you suspect a developmental reason for reluctance, such as coordination difficulties, discuss this with your family doctor, who can refer to a physiotherapist or occupational therapist for assessment and support.

Family Activity

Parents who are physically active themselves raise more physically active children than those who are not. Modelling an active lifestyle, and sharing physical activity as a family, is the most powerful long-term influence available. Family walks, cycling, swimming, and active holidays all build the associations between family time and physical activity that shape children�s habits and preferences for the long term.
