Resource summary

Aerobic capacity
  1. Definition
    1. Vo2 max: Highest rate of oxygen attainable during exercise
      1. Aerobic Capacity: Ability to work sub maximally for a long period of time
      2. Affecting Factors
        1. Genetics
          1. Inheriting types of muscle fibres. This affects 60% of AC
          2. Age
            1. Vo2 max declines with age. Aerobic training helps maintain aerobic capacity
            2. Gender
              1. Males have higher Vo2 than females by 15-30%. this is due to having bigger hearts and lungs
              2. Training
                1. Aerobically trained people are likely to have a larger vo2 max.
              3. Testing
                1. PWC 170
                  1. Is a test that predicts an athletes power output at a rate of 170 beats per minutes
                    1. Simple to set up and conduct
                      1. Need specialist equpiment
                      2. Multi stage fitness
                        1. Also know as the bleep test. Test your aerobic capacity
                          1. Only a prediction
