Almost all young Australians , including pre-schoolers, are not as physically active as they should be with 9 out of 10 young Australians sitting too much and not moving enough, according to the recommended Australian guidelines

[1]. A change towards sedentary lifestyles has happened for many people in many developed countries, including Australia [Australian Institute of Health and Welfare (2004) as cited in 2]. With improved access to mobile phones and the internet, children do not need to leave home to keep in contact with their friends outside of school. Children today are far less likely than children of earlier generations to walk or cycle to get from A to B, or to play outdoors [2].

Instead, children are spending more than the recommended two hours each day using electronic media. The SPANS study in New South Wales found that 61 per cent of boys and 45 per cent of girls in year six (aged approximately 11–12 years) were using more than two hours per day of electronic media. This percentage was higher in older age groups: in year 10, 78 per cent of boys and 67 per cent of girls fell into this group [2].

This increased screen time, combined with a lack of physical activity, can lead to young children being overweight, which often continues into adulthood [3]. In Australia, more than 1 in 4 children and adolescents are overweight or obese and it is predicted that 65 per cent of young Australians will be overweight or obese by 2020 [4]. Increases in the number of overweight and obese children leads to an increasing number of children who suffer with illnesses – including diabetes, asthma and mental health problems -as well as physical pain in muscles and joints, such as back pain [2]. Even type 2 diabetes – a chronic disease traditionally diagnosed only among adults – is now increasingly being detected in Australian children. Research also shows that overweight and obese children are more likely to be overweight or obese adults. Around 80 per cent of Australia’s obese adolescents will become obese adults [4]. This in turn can lead to a number of serious chronic conditions and even premature death [2].

Keeping children physically active

National guidelines for physical activity recommend infants and preschool children be physically active for at least three hours daily [5] and older children at least one hour [1, 6, 7]. The benefits of physical activity are enhanced further when children are more physically active than these recommended times [7]. The guidelines also provide recommendations for the types of physical activity that are appropriate for children.

National guidelines for sedentary behaviour recommend infants and preschool children should not be sedentary, restrained, or kept inactive for more than one hour at a time [5], and for older children these sedentary activities should be broken up as much as possible [1, 6]. These guidelines also recommend that the amount of time children spend sitting and watching television and using other electronic media (DVDs, computer and other electronic games) should be limited to one hour daily for infants [5] and preschool children and two hours daily for older children [1, 6].

Participation in physical activity

It is widely accepted that being physically active provides numerous health benefits. These have been described in a review by Buhlert-Smith, Hagiliassis [8] whose summary is based on works of the Australian Government Department of Health [6], the Centre for Community Child Health [3] and the World Health Organization [7], including:

Social benefits:

  • creates opportunities for social interaction, making friends and having fun
  • reduces anti-social behaviours
  • develops cooperation and teamwork skills

Emotional and intellectual benefits:

  • improves self-expression
  • improves self-esteem, confidence and independence
  • improves management of anxiety, stress and depression
  • improves concentration
  • promotes relaxation

Health benefits:

  • improves physical fitness by improving heart and lung functions
  • improves balance, coordination and movement skills
  • improves posture
  • improves flexibility
  • builds stronger muscles and bones
  • promotes healthy joint tissues
  • promotes healthy growth and development
  • reduces the risk of unhealthy weight gain by controlling the expenditure of energy
  • reduces the risk of developing type 2 diabetes and cardiovascular diseas

An active commute – walking or riding to school

Increased use of cars and the associated reduction in physical activity participation is a crucial factor in the rise in childhood obesity [4]. An easy way for school children to increase their physical activity participation is to walk or ride to school, but this type of commute is also in significant decline, with the 2015 Active Healthy Kids Australia [11] study finding:

  • 42 per cent decline in children walking or riding a bike or scooter to or from school, in the past 40 years, with no signs of this decline slowing down [11, p.18]
  • only 50 per cent of children and young people in Australia use active transport (bike, scooter) at least once a week to travel to or from school [11, p.11]
  • just 11 per cent of children ride a bike to or from school, however 90 per cent of Australian households have at least one child’s bike in working order [11, p.6]

The Australian Physiotherapy Association (APA) strongly advises parents to encourage their children to walk, ride a bike or scooter to school daily as an easy way for them to increase their physical activity participation. The study also found that active transport (through walking or riding a bike or scooter) provides a key contribution to the overall physical activity levels of children and young people in Australia and is feasible, given it can be easily incorporated into daily routines with minimal planning prior and involves little to no financial cost [11].
