A) Purpose: 1) To demonstrate advanced methods of determining
anaerobic capacity
2) To familiarize students with data obtained from a wingate
test.
Anaerobic or maximum muscular power: ability to exert high force while
contracting at a high speed.
The tests are short, max speed, and produce high power outputs
1-RM for Explosive Exercises (power clean, snatch, push jerk)
Vertical Jump
Margaria-Kalaman Test (time to sprint up staircase)
Increasing the weight lifted leads to decreased speed and vice versa.

Power ouput = work/time OR force x velocity
Work=
force x distance
Force = mass x acceleration
Power output: ability to exert a force at a given speed (a.k.a "speed strength")
(expressed as Watts or Watts/kg)
Review: the force production of a muscle is determined by the

crossbridges attached to the actin filament.

Anaerobic Capacity
-max rate of energy production by combined phosphagen and lactic acid energy
systems for moderate duration (up to 2 min.)
-quantified as max power output during 30 and 90 second
