    Origins

    Developed at the Wingate Institute in Israel byDr. Oded Bar-Or in the late 1970s

    Originally developed for use in children but was

    expanded to adults One of the most widely performed tests to

    assess anaerobic power

    Physiological Rationale

    Performance during the test is primarilydependent on the combination of the

    anaerobic energy pathways:

    Phosphagen System Glycolytic System

    Approximately 85% of ATP production during the

    test is accounted for by these systems.

    The WAnT requires a power level that is usually

    2-4 times greater than the participants VO2max.

    Physiological Rationale

  • 7/30/2019 HPHE 6720 - Topic 7

    5/29

    Variables that are Assessed

    Peak Anaerobic Power (Pk-AnP) A reflection of the ability of the limb muscles to produce

    high mechanical power in a short time.

    Peak power observed (usually over a 5 second period)

    during the 30-sec test. Typically occurs within the first 5-8 seconds of the 30-sec

    test.

    Is thought to mostly reflect the participants ability to usethe phosphagenic system.

    However, the glycolytic pathway is probably alsosignificantly involved

    Expressed both in absolute terms (Watts) and relative tothe participants bodyweight (Watts/kg)

    6/29

    Variables that are Assessed

    Mean Anaerobic Power (M-AnP) Reflects the endurance of the limb muscles (i.e. their

    ability to maintain extremely high power.

    The average anaerobic power over the 30-sec test

    Glycolytic pathway appears to contribute most to theparticipants mean aerobic power

    ~ 49% of ATP production

    Phosphagen system also contributes

    Subjects reduced there phosphagen levels to 70% of theiroriginal ATP values and 40% of their original CP values afterperforming the test.

    Expressed in both absolute terms (Watts) and relativeto the participants bodyweight (Watts/kg)

    Variables that are Assessed

    Total Work (w) The total work is based upon the number of

    revolutions at the end of the 30-sec test

    Expressed in both absolute terms (N

    m; J) and

    relative to the participants bodyweight (J/kg)

    Fatigue Index (FI)

    The degree of decrease in power from the peakanaerobic power to the lowest anaerobic power.

    Typically 40% or more

    Performing the Test

    Protocol has five distinct time periods:

    Prior Exercise

    5 min cycling at low intensity interspersed with 4-5 sprints of 4-6 seconds at

    prescribed force

    Recovery Interval

    2-5 minutes of rest or cycling against minimal force

    Acceleration Period

    1st Phase: cycle for 5-10 seconds at one-third of prescribed force at 20-50

    RPM

    2nd Phase: Cycle 1-5 seconds against approach to prescribed force at

    maximal RPM

    Alternate: Have subject reach maximal RPMs against no-load and drop the

    basket immediately at maximal RPMs

    Wingate Test

    Cycle at highest RPMs possible against prescribed force for 30 seconds

    Cool-Down Period

    2-3 minutes of cycling at low to moderate aerobic power level

    Optimization of Force (contd)

    General recommendations when using

    Monark cycle ergometer

    Adult Non-Athletes: 0.090 kp/kg body weight

    Adult Athletes: 0.100 kp/kg body weight

    Methodological Considerations

    Duration of Test Have ranged from 30 seconds to 2 min.

    General consensus is that a 30 second test is

    optimal. Motivation

    General consensus is that conventional

    encouragement of feedback does not affect results

    Methodological Considerations

    Warm-Up One study showed that a 15 minute intermittent

    warm-up (30 seconds on, 30 seconds off) on a

    treadmill increased mean power by ~7% but had noeffect on peak power.

    Regardless, warm-up should be standardized.

    Calculations

    Pk-AnP Should be expressed in Watts

    Best to use the newton (N) unit as the expression offorce (rather than kg)

    1 kg = 9.81 N

    Pk-AnP (Nmsec-1; W) = (N x (Rmax x 6))/5

    Example:

    A persons highest 5 second interval was 12 revolutions ata force setting of 4.6 kg (45 N)

    Pk-AnP = (45 x (12 x 6))/5 = 648 W

    Divide Pk-AnP by the persons bodyweight (kg) to

    get relative Pk-AnP

  • 7/30/2019 HPHE 6720 - Topic 7

    21/29

    Calculations

    Total Work w (Nm; J) = N x (R x 6)

    N = the force in Newtons

    R = the total number of revolutions in 30 seconds M-AnP

    M-AnP (W; Jsec-1) = total work / 30 s

    Divide M-AnP by the persons bodyweight (kg) toget relative M-AnP

    Fatigue Index

    FI (%) = ((Pk-AnP lowest AnP) / Pk-AnP) x 100
