We already suspected that Americans’ fitness levels Weren’t up to snuff, but now a study has confirmed it. Despite gyms and health clubs popping up all over the country, Americans are not, on the whole, a fit bunch. A study that has just been published in a recent issue of JAMA looked at the fitness levels of Americans aged 12 to 49 to prove this point.
In the study, over 5,000 Americans were tested on treadmills. The treadmills were sped up until the heart rate was 75 to 90% of the maximum predicted level for their age group. Oxygen consumption and heart rate were both monitored. Out of those tested, over 33% of teenagers and almost 14% of adults were found to have “low fitness levels.”
While 14% (13.9%, to be exact) of adults may not seem like a large portion, when this percentage is applied to the population of the United States, it works out that approximately 8.5 million adults are not in shape. That’s a huge number.
What’s more, these unfit people have higher cholesterol levels and systolic blood pressure, but their high-density lipoprotein levels (the good cholesterol that reduces heart disease risk) are low.
This means that these people have a significantly increased risk of heart disease and early death.
So, do you want to be one of the 8.5 million Americans suffering from poor health and low fitness levels? I didn’t think so. Take control now so that you can reduce your cardiovascular risk factors and enjoy a healthier and longer life.
