### Treadmill General Endurance VO2max Test

The objective of Treadmill General Endurance VO2max test is to monitor the development of the athlete's general endurance (VO2max).#### Required Resources Treadmill General Endurance VO2max Test

To undertake this test you will require:

- Treadmill where speed and grade of slope can be adjusted
- Stop watch
- Assistant.

### How to conduct the Treadmill General Endurance VO2max Test

The athlete runs on a treadmill to exhaustion. At timed stages during the run the slope of the treadmill is increased as detailed in the table below.

Time (minute) | km/hour | Slope |

0 | 11,3 | 0° |

1 | 11,3 | 2° |

2 | 11,3 | 4° |

3 | 11,3 | 6° |

4 | 11,3 | 8° |

5 | 11,3 | 10° |

6 | 11,3 | 11° |

7 | 11,3 | 12° |

8 | 11,3 | 13° |

9 | 11,3 | 14° |

10 | 11,3 | 15° |

11 | 11,3 | 16° |

12 | 11,3 | 17° |

13 | 11,3 | 18° |

14 | 11,3 | 19° |

15 | 11,3 | 20° |

The treadmill is set up with a speed of 11.3 km/hour (7.02 miles/hr) and a slope of 0° and the athlete commences the test. At minute intervals during the test the slope of the treadmill is adjusted.

The assistant starts the stop watch at the start of the test and stops it when the athlete is unable to continue - this ideally should be between 9 and 15 minutes.

### Analysis

Analysis of the result is by comparing it with the results of previous tests. It is expected that, with appropriate training between each test, the analysis would indicate an improvement.

From the total running time an estimate of the athlete's V02max can be calculated as follows:

From the total running time an estimate of the athlete's V02max can be calculated as follows:

- VO2max = 42 + (Time x 2)

"Time" is the total time of the test expressed in minutes and fractions.of a minute.

Example:

The athlete stopped the test after 13 minutes 15 seconds of running (13.25

minutes):

Example:

The athlete stopped the test after 13 minutes 15 seconds of running (13.25

minutes):

- VO2max = 42 + (13.25 x 2)
- VO2max = 68.5 mls/kg/min

### Target group

This Treadmill General Endurance VO2max Test is suitable for endurance athletes and players of endurance sports (eg football, rugby) but not for individuals where the test would be contraindicated.

### Reliability

Reliability would depend upon how strict the test is conducted and the individual's level of motivation to perform the test.

### Validity

There are published VO2max tables and the correlation to actual VO2max is high.
