1. Plyometrics Plyometrics are exercises based around having muscles exert maximum force in as short a time as possible, with the goal of increasing both speed and power. This training focuses on learning to move from a muscle extension to a contraction in a rapid or "explosive" way (Stretch-shorten-Cycle), for example with specialized repeated jumping. Plyometrics are primarily used by athletes to improve performance. Created by: stewart.kearney927@mod.uk Next Slide
