Transcript of Movement Analysis Project

Kinesiology Lab
Movement Analysis
Jarred Boyd Introduction Plyometrics: Specific exercises which encompass a rapid stretching of a muscle(s) that is undergoing eccentric stress and followed by a concentric, rapid contraction of that muscle(s) for the purpose of developing a forceful movement over a short period of time. Importance Athletes are able to increase explosive power and strength.
Linked to injury prevention
Health professionals are able to implement plyo as training/rehab modalities Components of Plyometrics Enhancing sports performance as well as functional movement is essential for the success of an athlete. Therefore, it is important to analyze the benefits of plyometrics as a training modality. Thesis Mechanical: Stretch-shorten-cycle (SSC): The muscle is eccentrically stretched then rapidly performs a concentric contraction. Elastic energy is stored and then coverted to kinetic energy. Neurological GTO: Excitatory threshold is increased causing larger contraction Summary of Components
MS: At the end of eccentric phase the spindle creates a larger stretch reflex. Mechanical and Neurological systems enable an athlete to move from 1 spot to another with greater speed, agility and power, while also limiting injury.
