The study analysed data between 2001 to 2008 from the US National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP) which collects information from 100 US hospitals which have an A&E.
During this period about 1.5 million adults over the age of 20 needed emergency treatment due to a motorcycle crash.
Bikers over the age of 60 were three times more likely to be admitted to hospital compared with those in their 20s and 30s – and two-and-a-half times more likely to sustain a serious injury.
The authors of the study said: “The greater severity of injuries among older adults may be due to the physiological changes that occur as the body ages, bone strength decreases, fat distribution may change and there is a decrease in the elasticity of the chest wall.
“Other factors such as a delayed reaction time, altered balance and worsening vision may also make older adults more prone to crashing.”
