Have tried Maffetone training with running and am not really convinced in it as a way to improve performance. I see it as great for building aerobic fitness after a layoff, general health and recovery efforts.
As far as training to improve is concerned then it's interval training all the way for me. I take the view that the quality of what you do is much more important than the quantity. Generally speaking, if you are not asking your body to do something it cannot do comfortably then you are not training.
The triathlete Mark Allen is always used to pitch the Maffetone approach but I've always been a little bit sceptical. I think it is very possible to train an already very fit athlete to become more efficient at a lower heart rate but remain to be convinced that low heart rate training can make an athlete very fit in the first place.
Low intensity training will definitely improve performance. And it's not just about efficiency. It promotes new capillaries, mitochondrial biogensis, and a transporter that brings lactate into the slow-twitch fibers where the krebs cycle can use it as fuel. So it will make you faster at every intensity level and there's no substitute for it. Even quality is not a substitute and without doing low intensity training you eventually plateau.
But that said, there are caveats: You need to do enough volume to actually stress your body (lotta people probably don't), and for someone very fit, that could be a lot. Relatedly, it may not be the most effective use of an athlete's available time.
And just like there's no substitute for easy training, there's also (I don't think) a substitute for quality. I think that by not doing high intensity training too, you're leaving progress on the table. Aside from training glycolitic capacity that all the best rowers have a lot of, you also train the transporter that brings lactate and hydrogen ions OUT of the fast twitch muscles while you're going hard. And you need both: you need the transporter that brings it out (it brings a hydrogen ion with it so that your muscles don't get too acidic and can keep firing), and also the transporter that brings it back IN so that your slowtwitch fibers / krebs system can burn it for fuel. In other words high intensity and low intensity are like the yin and the yang of endurance sports.
I suspect that the people who have really benefited from Maffetone training is because they neglected low intensity for too long, were maybe long-term starting to stagnate and needed to switch thigns up. Also triathlon is gonna be different from rowing in its energy demands. There's no counterfactual of course but i suspect that a lot of people who benefit from Maffetone could also do well and maybe even better with a train high / train low approach. Not to mention that it's more fun
