Document Summary

Determinants of speed: muscle properties, neural drive, mobility, technique. Anthropometric variables: anthropometric variables can affect both speed and agility, ex. someone with longer legs will be able to sprint faster, shorter person can change direction faster (but, Some variables genetically predetermined still generalizations: certain things we are limited by, but can modify with training, others can be modified with training; ex. decreasing fat mass, will enhance speed. Postural control, stability: neuromuscular skill and coordination (ex. arm coming up with opposite leg to ensure maximum sprinting speed, these drills done in warmup exercises. Increasing type 2 area = more atp/pcr stores: greater ability to restore pcr stores through aerobic metabolism. ** sprint training helps to maintain cellular homeostasis. Trying to increase neural drive to muscle to make it activate more quickly. Recovery in between repeated efforts: oxidative capacity, capillarization, avo2diff, vo2max are important in pcr resynthesis. Speed program design: technique *, acceleration, maximal velocity.
