Black or White: Who Should Exercise More?

Getting enough exercise has a great impact on the present situation of our bodies as well as the future of our health. From getting enough sleep to craving healthy meals, we just can’t exhaust the goodness of workouts. While not getting off can do the reverse and affect how we control our body mass, cardiovascular health, metabolism and body fat, we need to actually learn how to know we have gotten just enough to help our system function properly as extreme exercising is also not good for our health.

When Should Workouts Be Enough?

Well, often times we get too conscious of our health and feel terrible that we are not going to the gym enough. But new scientific findings suggest instead of being regretful, we should reconsider how much we work out per day because too much of it can hurt our body.

According to the recent study, a white man stands a chance of facing a health risk from extreme exercising.

The study further shows that while the black man can withstand over 7 hours of exercise, the white man may experience stress on the arteries, leading to higher coronary artery calcification(CAC). In fact, at the highest level, there was no additional risk for black men, but there was 86 percent increased risk for the white men.

CAC is a buildup of plaque in the heart arteries. It is an indicator that the sufferer is developing traits of a heart disease.

This finding also proves that genes have the capacity of affecting or determining the physical strength of a person.

Africans are generally known for their history of hard work. Though endurance training enhances physical strength for people of all races, the black man naturally has the tendency to be stronger.

Researchers from Chicago discovered that White men who work out at least 7½ hours a week are nearly twice as likely to suffer from heart disease as those who do a moderate amount of exercise.

From the new study, the researchers looked at the health history of people within the age ranges of 18-20, and 43-55, who exercised often over a 25 year period (1985 – 2011). It was discovered that very active white men are about 86% more likely to experience a heart disease by middle age.

The team of researchers from the University of Illinois at Chicago and Kaiser Permanente studied the physical activity patterns of 3,175 black and white participants in the longterm CARDIA to ascertain the presence of CAC.

Split into 3 groups the researchers discovered the following:

  • 1st Group exercised below the national guidelines in less than 150 minutes a week.
  • 2nd Group met the national guidelines of 150 minutes of exercise a week
  • 3rd Group exercised 3 times more than the national guidelines of over 450 minutes a week.

The results from the various groups were later re-grouped under gender and race.

In all, those in group three were 27 percent more likely to have CAC by middle age when compared to those in group one.

According to Deepika Laddu, assistant professor of physical therapy at the UIC College of Applied Health Sciences, they expected to see that higher levels of physical activity over time would associate with lower levels of CAC; the reverse was the case.

Professor laddu suggested that further investigation should be carried out to determine the biological determinants of the CAC risk levels in the different races, amongst people who have high rates of physical activity.

This would throw more light into the causative factors of the CAC risk levels in the different races, especially for the white participants, who have demonstrated a greater susceptibility to CAC over the same workout level.

Dr. Jamal Rana, a cardiologist at Kaiser Permanente in Oakland concurs that a high level of exercise over time may put a strain on the arteries. However, he added that the study has not authenticated that the plaque buildup in the artery can rupture to cause a heart attack.

Rana emphasizes still the importance of exercise to the general well-being, stating that it is not advisable that anybody should stop exercising. The new study only suggests that it should be done within a healthy frame of time.

Another health condition associated with extreme exercising is known as rhabdomyolysis. This is the condition where the muscles break down and release toxins into the body. This ultimately leads to kidney failure.
