It seems reasonable to believe that physical fitness is linked to brain and heart health, especially as people age. A study in a recent article gives evidence to this idea. Researchers conducted an experiment in middle-aged adults around the age of forty. The participants were given a treadmill test to assess their physical fitness. The test mainly assessed the heart and brain health of the participant by measuring the blood pressure and how long the participant could run before they reached a certain heart rate. An MRI of their brain was also taken. After about twenty years the researchers looked at the heart and brain health of the same participants. The researchers found that the people who did not preform as well on the treadmill test had around one to two years of extra brain aging compared to those who performed well on the treadmill test. The researchers concluded that those who did not preform well on the treadmill test had smaller brains twenty years later than those that did preform well on the treadmill test. They also found that people who have heart disease have a stronger link between physical fitness and brain health.
Throughout KSMLeadership, it is discussed how many people refuse to be accountable for what happens to them in their lives because they would rather put the blame on someone else. For example, someone who is born with a higher susceptibility for heart disease due to their genetics may feel inclined to blame their genetics when they develop heart problems or brain problems. However, from what I have come to understand in class, this person should be held accountable for what happened to them because even though they had a higher likelihood of developing these problems there are things they that they could have done to prevent it. Based on the conclusions in this article, physical fitness and exercise could be a key method to lessen the likelihood of these problems. Therefore in the example above the person should have done everything in their capabilities to lower their likelihood of developing heart problems and brain aging by exercising and being physically fit.
