In my opinion, the article doesn't really nail down what high intensity is. They elude to aerobic high intensity near VO2 max, or near lactic threshold. I define high intensity as anaerobic interval training, or a level well above lactic threshold. This has been shown to stimulate the body to produce natural HGH, which is what helps retain muscle mass and strength as we get old. It's hard on the CNS so more recovery is needed.
I think it depends on what you're training for. If you're targeting a 10k marathon swim or an ironman triathlon, your training intensity will be generally lower than someone who is training for the 50 free. Simulate race conditions in your training, whatever "race conditions" mean to you.
