Alexander Brooker, a rugby player from England answered a question.
The question is how do you combine the two forms of training without causing negative effects?
His answer was, he has a huge respect to you for playing Aussie Rules Footy – I consider it one of the hardest, if not the hardest sport on Earth. It requires you to be very proficient in many different biomotor capabilities, plus you need to be a bit psycho too!
You haven’t mentioned how long your preseason is, what level of athlete you are in regards to the Process of Attaining Sports Mastery, your previous training, competition calendar, how old you are, physical parameter measurements etc., so this means I cannot give you a definitive answer. However, I can give you a framework and some ideas of how to manage the training process.
He personally view ARF as an aerobic-alactic sport. There is an obvious demand for a very powerful aerobic system (15km per match, length of the game, etc.) and also a powerful alactic system is needed for the jumps, tackles, sprints etc.
Lastly, if you program the training process correctly, there will be NO NEGATIVE effects between improving the athletic and aerobic systems, and contrary to popular belief, they will actually COMPLEMENT each other.
