Principles of exercise testing
    Include:
     Use of maximal and sub-maximal tests
       VO2 max
       Exercise stress testing
       Cardiac patient rehabilitation
                                                             2
    Why measure physiological 
    fitness?
       To monitor  effectiveness of a training programme for an 
        athlete
       To monitor recovery from MI
                                                                3
    How to determine aerobic 
    fitness?
       Measure maximum  rate at which the body is able to take up 
        and use O   maximal testing
                 2
       Called VO2 max
                     3   -1  -1
        Measured in cm kg min  
       Higher VO2 max the greater the aerobic fitness of the 
        individual
                                                              4
   VO2 max
     Measured by getting the person to run on a treadmill whilst 
      breathing in a measured gas supply
     As intensity of exercise increased (increasing speed or 
      gradient of treadmill) more O  taken in until it reaches a 
                           2
      maximum level that does not change even if exercise 
      intensity increased further.

   VO2 max
