Did you know? The force placed on your knees when walking is three times your body weight. When climbing stairs the force can be up to 10 times your body weight.

Being overweight or obese accelerates wear on the joints by limiting how well your body can move.  Generally, being overweight or obese results in difficulty squatting, running and climbing stairs. Biomechanically this is explained because the force on the knees is about three times a person’s body weight with walking. When you factor in other activities such as running or climbing, these forces can reach six to 10 times the body weight.

For every kilo you are overweight, 3 extra kilos of pressure is placed on the knees.

Overweight employees are 15% more likely to suffer a workplace injury.
For obese employees, this figure rises to 48%. more likely.


Obesity negatively affects balance and postural stability, increasing the risk of falling. Studies of the influence of obesity on postural stability in adults and among the elderly have found that obesity is associated with impaired postural balance, even in relatively young individuals. Obesity and the risk of injury doesn’t discriminate. However, this isn’t the only way that obesity is linked to injury.

There is a higher prevalence of sleep-disordered breathing among obese people. This has been identified as a contributing factor to increased incidence of transport accidents in obese people. Research has shown that adults with a higher BMI were twice as likely as adults with BMI in the normal range to experience injury. Overweight and obese workers also report a greater incidence of work-restricting pain in the neck, back and lower extremities.
