It's called "boosting", it's a way for paralympians with spinal injuries to cheat - and one expert says three out of 10 of them may be doing it.

'When able-bodied competitors engage in hard physical activities like running or swimming, blood pressure and heart rate increase automatically. Athletes with spinal injuries do not get that response. "Boosting" is a short cut to higher blood pressure and the improved performance that comes with it.

In medical terms it's defined as the deliberate induction of a dangerous condition common to quadriplegics called autonomic dysreflexia (AD). Many everyday activities that cause discomfort, even something as trivial as sunburn, can set off the condition naturally.'
