Lab 1Assessing Anaerobic Capabilities Using

the Wingate Test

Wingate Anaerobic Test (WanT)

• Is the most popular anaerobic test

• Gauges the energy produced during phosphagen breakdown (ATP-PC system) and anaerobic glycolysis

Three measures derived from the WanT

1.Peak power– Reflects the phosphagen component– Is the greatest work performed during any five-

second period2. Mean power

– Reflects the glycolytic and phosphagen components– Is the total work performed during the 30-second test

3. Fatigue Index– Reflects the anaerobic fatigue capabilities of the

active muscle– Higher fatigue index indicates a greater proportion of

fast-twitch fibers

Example for Peak Power, Mean Power, and Fatigue Index Computations

• 150 lb. healthy female in her mid-twenties

Seconds Revolutions

0-5 8

5-10 9

10-15 8

15-20 7

20-25 6

25-30 5

Peak Power Formula

0.075 kg resistance x kg of body weight

x 6 (the distance in m traveled by the cycle ergometer flywheel in one revolution)

x greatest number of revolutions of the flywheel in a 5-second period

= peak power kgm · 5 sec-1

To convert to watts:

peak power kgm · 5 sec-1 x 12 / 6.12

Peak Power Example

• 150 lb. healthy female in her mid-twenties

0.075 x 68 = 5

x 6 = 30

x 9 = 270 kgm · 5 sec-1

x 12 / 6.12 = 529.4 Watts

Percentile rank = 80 (Table 1.1)

Mean Power Formula

0.075 kg resistance x kg of body weight

x 6

x number of revolutions of the flywheel in the 30-second period

= mean power kgm · 30 sec-1

To convert to Watts:

Mean power kgm · 30 sec-1 x 2 / 6.12

Mean Power Example

• 150 lb. healthy female in her mid-twenties

0.075 x 68 = 5

x 6 = 30

x 43 = 1290 kgm · 30 sec-1

x 2 / 6.12 = 421.5 Watts

Percentile rank = 80 (Table 1.2)

Fatigue Index Formula

greatest work in 5-sec. period − lowest work performed in 5-sec. period

greatest work in 5-sec. period x 100

Fatigue Index Example

9 − 5 = 4/9 = .444

x 100 = 44.4

Percentile rank = 80 (Table 1.1)
