There are gaps in current training regimens for astronauts on the ISS that result in Plyometric Deconditioning
As long-term Lunar and Martian exploratory missions are underway; a need was identified to provide plyometric exercise countermeasures to combat physiological deconditioning in non-Earth gravity environments.
Performing Plyometrics
All explosive forces generated by the human body are Plyometric in nature. There are three stages to Plyometric motion:
When performing Plyometric motion on Earth, there is usually just one surface the human body is in contact with - the ground. Furthermore, based on how the storing/release of potential energy works, all Plyometric motion on Earth requires Gravity.
Problem: No gravity on the ISS!
Our Hypothesis: If we invert the frame of reference - i.e. brace the human being such that a flat contact surface applies the ‘inverse’ of the force that the human would apply on the ground on Earth, we could exercise plyometrics in space!
