The one leg stance test is familiar to any runner who has ever sprained an ankle. I fully understood the importance of this after learning Lee Saxby’s ‘Born to Run’ running screen which places this as one of the crucial milestones to master.
You cannot expect to do thousands of one-leg jumps without injury risk, i.e. running, if you cannot master this simple milestone first.
* In the scientific literature the one-leg stance is referred to more technically as ‘uni-pedal stance’ – search for this if you’re interested in the research. This article provides a good starting point.
