What is VO2max?
VO2 max, or maximal oxygen uptake, is one factor that can determine an player's capacity to perform sustained exercise and is linked to aerobic endurance. VO2 max refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. It is measured as "milliliters of oxygen used in one minute per kilogram of body weight."
This measurement is generally considered the best indicator of an player's cardiovascular fitness and aerobic endurance.
How to Perform the Cooper Test
To undertake this test you will require:400 metre track, Stopwatch, Whistle, Assistant.
This test requires the athlete to run as far as possible in 12 minutes.
- The athlete should perform a standard warm up.
- The assistant gives the command “GO”, starts the stopwatch and the athlete commences the test.
- The assistant keeps the athlete informed of the remaining time at the end of each lap (400m).
- The assistant blows the whistle when the 12 minutes has elapsed and records the distance the athlete covered to the nearest 10 metres.
Calculating VO2max
An estimate of your VO2max can be calculated as follows:
- (Distance covered in metres - 504.9) ÷ 44.73 = VO2max

VO2max and Football
- Soccer players posses excellent endurance with VO2max reported to range between 55 and 70 ml/kg/min in elite performers (Bangsbo et al, Reilly et al).
- VO2 Max varies according to playing position. For outfield players, midfielders have significantly greater aerobic power values whilst central defenders have the lowest values.
- The game is played at an average intensity close to the lactate threshold - approximately 80-90% of maximum heart rate (Helgerud et al, Reilly et al).
- The greater a player's aerobic capacity (VO2max), the more ground they cover during a typical game and the number of sprints completed in a game also increases (Reilly et al, Smaros et al).
- By improving the VO2max of youth soccer players by 11% over an 8 week period, a 20% increase in total distance covered during competitive match play was manifested, along with a 23% increase in involvements with the ball and a 100% increase in the number of sprints performed by each player (Reilly et al).
Improving VO2max
- Basic aerobic endurance training that follows the ACSM's recommended guidelines for cardiorespiratory fitness training is known to improve VO2max.
- For elite players expecting high increases in VO2max high intensity interval training (HIIT) should be performed. HIIT is a method of training that involves performing intervals of high intensity exercise interspersed with rest intervals of lower intensity exercise. Generally this involves mximizing the time spent at or near to the individuals VO2max.
- To improve VO2max your high intensity intervals should be performed at an intensity of roughly 90% of VO2max (this correlates to approximately 95% of maximum heart rate).
- The length of each high intensity period should be roughly 75% of the maximum amount of time that you could last at this intensity before fatiguing.
- Rest intervals can be 2:1 for untrained players and closer to 1:1 for trained athletes.
- During your rest intervals, you should carry on your exercise activity while reducing your intensity level to approximately 70% of maximum heart rate.
- Time spent at high intensity during the bouts should be 20-30 mins total.
- Perform HIIT now more than 2-3 times a week.
- Many other factors affect VO2max: Age, Gender, Body Composition, Fitness level, Form of Exercise, Genetics.
- Individuals VO2max will improve at different rates.
