GRIT: PRESCRIPTION FITNESS
EXERCISE– BUT WHAT TYPE AND HOW MUCH?
We all know that we should be exercising regularly. Our doctors tell us. The government tells us. Even celebrities tell us. And yet, despite the copious amounts of literature expounding the dangers of inactivity and its associated diseases, an astonishingly high number of us do not fulfill the recommended guidelines for physical fitness.
And when we say ‘exercise’ – what should this entail? Will a brisk walk suffice or should we be exhausting ourselves until we are gasping for air? The guidelines themselves have proved to be unclear: In 2013 ACSM (American College of Sports Medicine) recommended that, to reduce the risk of developing cardiovascular disease (CVD), we engage in an unspecified combination of moderate-intensity and vigorous-intensity exercise 3-5 days per week. At present there is no clear prescription for engaging in exercise of vigorous intensity vs. moderate intensity; a gap in the guidelines exists.
