Measures of Anaerobic Indicators An overview
Anaerobic Indices • Not normally measured as an indication of fitness since are not considered to be related to health • Are not used in day-to-day life • Mainly important in the assessment of athletes • Defined as the ability to do short-term bursts of high-intensity work.
Anaerobic Energy Production • Without Oxygen • 1. ATP-PC • 2. Glycolysis
Lab Tests • 1. Margaria-Kalamen • 2. Muscle Biopsy • 3. Anerobic Sprint Test • 4. Sargent Jump Reach Test • 5. Manahan-Gutin Step Test • 6. Wingate
Margaria Kalamen • Measures the ability of a subject to climb steps at maximal speed • The time it takes to climb from the 3rd to the 9th step in a stairway (usually have switch plates on the steps which determine the start and stop times)
Margaria Kalamen • Usually under 3 seconds so is a test of the phosphagen system • Power (kgm/sec) = Work ÷ Time = Force x Distance ÷ Time • Force = BW (kg) • Distance = sum of step ht (meters) • Time = amount of time to climb stairs (sec)
Muscle Biopsy • Measure anaerobic enzymes • Disadvantages • painful • expensive • invasive • possibly not representative of the entire muscle
Sprint Test • Time to run a certain distance (usually 40-60 yards)
Sargent Jump Reach Test • Maximal Vertical Jump Test • Hard to account for BW so try to include a rate constant for a falling body in the equation • Power (kgm/sec) = 2.21 x BW (kg) x jump height (m)
Manahan-Gutin Step Test • The number of times a subject can raise their body on a bench in a period of 1 minute • Power (kgm/min) = BW (kg) x # steps in 1 minute x Bench ht (m)
Wingate Cycle Ergometer Test • Assesses both anaerobic energy systems • 30 second test • Load = BW (kg) x .075 • Work (kgm) = load (kg) x # pedal revolutions x 6 meters
Anaerobic Power • Greatest work performed in a 5 second period • Reflects the phosphagen system • AP (kgm) = highest revs in 5s x 6mx Resistance • multiply by 12 to convert to kgm/min • divide by 6.12 to convert to Watts
Anaerobic Capacity • Reflects glycolytic + phosphagen system • AC (kgm) = total revs in 30s x 6m x Resistance • multiply by 2 to convert to kgm/min • divide by 6.12 to convert to Watts
