Physical Activity Can Improve Your Health

One of the South African Food Based Dietary Guidelines is “be active”. The human body is built to move but we often disregard physical activity in our wellness goals. The World Health Organisation (WHO) defines physical activity as “any bodily movement produced by skeletal muscles that requires energy expenditure”, the important part of the statement is that it must use up energy1,2.

Our bodies move all day but this does not use as much calories as we often take in. Adding additional exercise helps burn more calories and has many health benefits. Before we talk of the benefits, what is considered exercise? You don’t need to be a “gym bunny” and live at the gym to be physically active. There are many ways to add in some extra energy burning activities.

  • The world health organisation recommends that following exercise for different age groups:
    Children and youth aged 5–17 should get least 60 minutes of moderate- to vigorous-intensity physical activity daily.
  • Adults aged 18–64 should do at least 150 minutes of moderate-intensity aerobic physical activity3

Aerobic activity is not just aerobics but any exercise that gets the heart pumping. The American Physical Activity Guidelines send a very encouraging message to the public. Everyone can choose different activities that they enjoy such as dancing, martial arts, tennis, canoeing, swimming, lifting weights, and even just walking. You have the freedom to select when to exercise to best fit into your busy lifestyle4.
