More Frequent, Intense Exercise Is Better

I remember when I was young I had a swim meet on the weekend. But the meet wasn't due to start until the afternoon. And so I asked my dad if he wanted to go play tennis. And he said no and that I should probably rest before my meet rather than go and play tennis. And this was probably a good idea. I was able to rest up and focus on my races to come. But I find it interesting how the frequency and intensity of our exercise changes as we grow up from childhood, through adolescence, into our teens and eventually as adults. When we were younger we thought nothing of having swim practice in the morning, playing football at recess and lunch, followed by swim practice again in the evening. And if there was time we'd fit in some more time to play with our neighbourhood friends. Now if most of us do one activity in a day we're spent for that day and possibly for days after. One client and friend, LM, enjoys going cat and heli skiing. He says that he tends to have to 'fake sore' with the rest of the group on the trip regarding his fatigue and DOMS (i.e. muscle soreness). Everyone else is suffering after an intense day of carving powder and so he 'fakes sore' in order to fit in. But how much exercise is enough? And hard should we push ourselves? A new study out of Oxford tells us that more is better when it comes to exercise. And the benefits were greater with more intense exercise. Here's what they did. Researchers observed the fitness habits of over 90,000 adults, both male and female. And they wanted to see the impact of exercise intensity and frequency on cardiovascular (CV) health....

Does Exercise Need to be Vigorous?

I remember going to a local business a few years back to give a corporate health presentation. And before the presentation I connected with someone I knew previously in the foyer. And catching up for a few minutes I excused myself in order to go get ready. The person I knew headed off in the opposite direction. I asked if they were going to attend. And here's what they said... 'No, I already do yoga regularly, so I'm good. But good luck with your talk'. I guess this would be similar to declining a presentation by a financial planner because you already have a bank account. Sure bank accounts and investing are both in the financial sector but that's about where the similarities end. Maybe to the average person physical fitness is all the same. Whether you want to do yoga, Pilates or strength training, they are all equivalent and offer the same benefits. New research says this isn't so. A new study published in the Journal of American Medical Association (JAMA) looked a the effects of exercise on lowering disease and extending lifespan. On a side note I like how our friend Sam Spinelli uses the term 'healthspan' rather than 'lifestyle'. Anyways, the authors of the study reviewed over 400,000 people, evenly split as male and female with an average age of 42 over a period from 1997-2013. The participants would then self report the duration and intensity of their daily exercise. They wanted to see the difference of moderate and vigorous exercise on all cause mortality. In other words, when you push hard with your exercise how does this compare to less intense exercise on death due to cardiovascular disease (CVD) or cancer. Exercise intensity can be defined as to how much energy it burns compared to sitting at...
