Ch 7
Sprinting: Horizontal Power
Introduction
Anaerobic fitness are primarily dependent upon
ATP & Creatine phosphate
What 2 energy systems?
Phosphagen
Fast glycolysis
Popular horizontal power tests are:
Short sprints (40 yd to 800 m)
Standing long jump
Various shuttle runs
What are the 2 most popular in the US?
40 yd sprint (football)
60 yd sprint (baseball)
Anatomical Rationale
It has been suggested that faster sprinters have greater
forward propulsion b/c they have more forceful & powerful
Hamstrings
Hip extensors & knee flexors
Ankle plantar flexors
What about the arms?
Primarily used for balance
Biomechanical Rationale
Technically, anaerobic power is not measured in sprints b/c
of the
Lack of a true vertical distance component
Only horizontal distance is known, but
It cannot be used to calculate work as defined by a physicist (w =
F X D)
