Should modern sport test not just natural talent, but also training methods and technology, or does that make competition unfair?

In my opinion i think that modern sport should also test training methods and technology.I think that because if new training methods are tested people can find numerous ways to get stronger and stay fit.Also,by using technology people can train more excesively.Although there are a bunch of good things about this there are some negative things that could be argued.One of which is the fact that people could use illegal methods to get stronger and therefore obtain an unfair advantage over the other competitor.Taking all the above into considaration i think that modern sport should also test training methods and technology because the benefits of doing this outweights the disadvantages.
