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....
