Anaerobic Power and Capacity Flashcards
Why assess the anaerobic system?
relevant to occupations, sport, and ADLs
Anaerobic testing considerations:
- duration
- intensity
- resistance
- ergometry
- protocol
- tester control
- biological factors
Tester control includes:
- rested state of the individual: ATP-CP stores, glycogen, absence of DOMS
- motivation
- ergometry/mode of exercise
- time of day
- protocol (resistance setting, speed/grade)
Biological factors include:
- body mass
- tolerance and buffering capacity
- muscle fibre type (metabolism, size, recruitment)
- fitness level
- age and gender
Anaerobic alactic power aka…
ATP-PCr power
Margaria-Kalamen test protocol:
- running start (20 ft)
- ascend steps 3 at a time
- 1.05m vertical
What is used to calculate power in the Margaria-Kalamen test?
- kg
- height travelled
- time to travel
1 kg*m/s^2 =
1 Newton
1 Nm/s =
1 Watt
Limitations of Margaria-Kalamen test:
- accuracy issues with timing
- need standard/accurate measure of stair heights (17.5 cm)
Clemons & Harrison modification:
- no lead in
- 2 steps at a time
- 2.04 m vertical
Margaria-Kalamen test is testing….
anaerobic alactic (ATP-PCr_ power
Wingate test is testing…
anaerobic alactic (ATP-PCr_ power
Wingate protocol:
- all out pedaling test on a Monark cycle ergometer
- optimal (high) resistance setting adapted for various populations
- trained = 95 g/kg
- active = 85 g/kg
- sedentary = 75 g/kg
Total power output achieved during first _____ of Wingate test.
10 seconds
Quebec 10 sec. test:
- 2 trials of 10s at resistance of 90 g/kg
- use highest total output
Peak glycolytic power output occurs between _____ and ____ power.
- alactic
- aerobic
Cunningham-Faulkner test:
- treadmill
- 8 ph at 20% grade, modification 7.5-8.5 depending on previously determined aerobic fitness
- timed test (starts when the subject begins to run and stops when they touch the handrails)
Boscoe 60s vertical jump test:
- repetitive jumping using force mat to measure power based on total flight time (total height)
- can e modified to a 15s test
Which protocols can be modified for upper body power and capacity?
- cycle ergometer protocols (eg. Wingate)
- rowing (optimal resistance varied depending on gender and if heavy or light weight rower)
How does the Wingate have high utility with robust outcomes?
- alactic power
- alactic capacity
- glycolytic power
- glycolytic capability (modification)
- can also be used to determine fatigueability
Fatigued indexes are usually expressed as…
a % drop in PO
Fatigue indexes indicates…
loss of muscular performance due to various fatigue factors
Fatigue factors:
- depletion of ATP-CP
- accumulation of H+/Ca++ (buffering capacity)
- tolerance to pain
Anaerobic field testing is typically..
- sport specific
- typically involve repetitive all out sprint tasks with a timed component
Anaerobic capacity ice skating test:
- sprint 12x a distance of 60 ft
- time reported in seconds
- reliability of r = 0.96
FIFA interval sprint test:
- 6 x 40m sprint (< 1:30 rest between)
- all intervals < 6.2s for international refs
Running based on Anaerobic Sprint test (RAST):
- 6 x 35m sprints on track
- 10 second rest between to allow turnaround
- record time to complete all six sprints
- power = weight x distance^2 / time^2
- from 6 times you may also calculate the power for each run then determine max, min, fatigue index
Factors affecting running tests:
- timing systems vs stop watch
- start stance
- surface
- shoes (cleats/spikes?)
- environmental conditions
- coordination
Post test considerations:
- cool down should be for a minimum of 5 min. of active recovery
- if feeling faint, lay down with feet up
- should assign a buddy to supervise the cool down
- fruit juice
