Vertical Oscillation is one of the most common values in running evaluations. Running is a movement in which a human being alternates between his left and right feet, which creates "up and down movement" compared to movement on wheels such as a bicycle. Vertical Oscillation is the magnitude of this upward and downward movement measured by a sensor at the pelvis.
However, the optimization of human walking and running is so great that in the world of elite sports, this up and down movement is almost zero, and if you watch a slow video of a 100m run, you can see that the elite athletes' heads do not move up and down, but their lower body moves like a wheel and moves smoothly.
Nevertheless, there is always physical up and down movement, and less up and down movement is an indicator of being able to run efficiently "like a wheel".
Does Vertical Oscillation matter?
Vertical Oscillation has a large inverse correlation with speed (Vertical Oscillation becomes smaller when speed is increased), but it is still useful to evaluate the competition level due to the large individual differences.
However, it's also true that elite runners end up with almost similar values.
Therefore, LEOMO also offers an MPI called Smoothness as a value to evaluate your running as a whole. This has the potential to be a more accurate assessment of higher level athletes than Vertical Oscillation.
The value of Vertical Oscillation
The unit is cm, and the width of the up and down is expressed in terms of length.
The shorter the run, the more efficient it is.
It is often inversely correlated with speed (getting smaller as speed increases), but may not change depending on the athlete level.
- Sacrum placement
Use Adhesive tape
Attach at the Sacrum. (The largest bone at the base of the spine.)
Proper placement (as seen in the image above) orients the LED in the upper left position.
Real-time data & analysis
Vertical Oscillation can be observed in real-time during the activity.
Coaches can also access the scores in real-time, with the LEOMO LVS.
