All the anaerobic work in the world will not change his muscle fiber composition so you have to work with what he has. Sure you can make him a little quicker but it is not what is important right now. Concentrate on his long term development with building his aerobic capacity
You really should rethink your thought on the first sentence. Any of my students in my undergrad muscle physiology class can explain how wrong your statement is. Maybe you've never take a physiology class but what you're saying is similar to saying lifting weights will not change muscle cross-sectional area.
I'm not sure what level of physiology you teach, but you should be instructing that type 1 slow twitch fibers will not change into fast type 2 fibers. Any evidence contrary to this is extremely questionable. If any changes did occur it would be on a very minute level if at all and still would be not proven. If you are teaching your students something else I feel bad for them.
You can change the characteristics of type 2 fibers in terms of mitochondrial density.
We all have a mix. But those who predominantly rely on type 1 fibers need to be trained differently than those who are predominantly type 2. It's crazy how different two people can be. You can send them both off to do a max 400 and one will have a blood lactate level of 16-18 five minutes after the effort and the other 6-8. The latter will also clear it quicker. Hmmm....different rest periods are maybe needed for adaptations to the workout. Try to think about your science being applied.
It's just one of the many variables into understanding how each athlete is different. There is a ton of advice on this site about people using a sample size of one (themselves) to explain how everyone should train. Then their are people that claim to teach college (I hope not!) giving false information.
