I’m often asked, who is this test is for and whether a 'casual athlete' could benefit from this. And to be honest it depends what sort of person you are and what your reasons are for having one. For example, if you want bragging rights at your club as to who has the highest VO2 , then go for it!
By their nature sports people are competitive, right? I know I am (my peak VO2 is 41.6 ml/kg/min-1 , in case you’re wondering?).
If you’re about to embark on a training programme, and want to accurately be able to test the benefits of all your hard work, I’d say that’s a great reason.
If you’re already a keen athlete of some sort, and want to know if CPET can give you some physiological data to enhance and improve your training, I’d say that’s a great reason also.
If you feel your performance has dropped off, or you’ve noticed you’re getting symptoms for example of breathlessness, a CPET could help you get answers.
