This is a theme we will keep coming back to again and again. There is yet one more article published this week that discusses how moderate to vigorous physical activity (MVPA) produces substantial health benefits.

This is based on the 2008 Physical Activity Guidelines for Americans that recommends at least 150 minutes per week of moderate of 75 minutes per week of vigorous intensity physical exercise.

This study was done to figure out whether 10 minute bouts of more sustained activity make a difference over and above the usual amount of regular activity. The conclusion the study reached is that it doesn’t matter how the exercise is done, as long as it is done. If these results are correct and replicated, it means that people and trainers can focus on methods of exercise that don’t necessarily include bouts of increased training.

More importantly though, the message again is the same. The more you exercise, the better the mortality benefits are with the benefits tapering off once the exercise levels reach a certain peak (in this case 96 mins / day) for Q3 and 147 mins/day for Q4), though this study measured exercise using an accelerometer and hence also included daily regular activity, rather than a structured activity routine.

In 2012, in the Lancet, Wen CP and Wu H  put this in perspective, with this telling graph that shows how physical inactivity is as bad as smoking.

So essentially, we come back to the same refrain. Get off your ass. Do something…anything and it helps.
