PERSONAL TRAINING What's Blood Got to Do with IT?

What’s Blood Got to Do With it?

Not surprisingly…….everything. What’s in it, how it’s comprised, how it’s hydrated and how it’s pressurized, are but a few of the “to do with its”. Let’s focus on the latter, the pressurization of your blood. Blood pressure is one of those silent killers out there responsible for a host of illnesses from cardio vascular disease to aneurisms and strokes. It is silent, in that you really can’t feel your blood pressure to know if it’s within acceptable ranges, without regular testing. 120 over 80 have long been the established norm values for blood pressure. But what’s in those numbers? Take the 120 number for example. That number represents your Systolic Blood Pressure. Now, what does that mean? Now add in the lower number, the Diastolic Blood Pressure of 80, and it gets more confusing right? Here is a simple explanation.

First imagine your arteries, those are the blood vessels that carry oxygenated blood away from your heart, now imagine them as long skinny balloons. When your heart contracts to force blood through your system that force exerts a pressure on that skinny balloon. The Sistolic BP is the pressure exerted on your arteries in the contraction phase of the heart. That pressure should be no greater than 120. Once the heart contracts, it next relaxes to begin the back and forth contract/relax process over and over again…...the beating of your heart. It is in the relaxation phase that the Diastolic BP is measured. It should be no greater than 80.

Now let’s take this skinny balloon concept and repeatedly inflate it. Now deflate it, blow it up again, deflate it again, but now really blow it up, that’s right fatten it up, now deflate it and do that over and over again. At some point this balloon could develop a weak spot, particularly susceptible in these latter more significant inflations, as more stress is placed on it, as it gets overstretched and then under relaxed again and again. Your vascular system works the same way. This over pressurization can wear away the inner lining of the vessel itself. 170/90, 180/100, 190/110 and eventually, a risk of breaking the balloon comes in to play.

So what to do? Use diet and exercise to insure you are within your healthy weight range for your height. Have regular checkups with your Doctor. On the diet side, look at your sodium intake. If you eat a lot of processed or canned foods and or dine out often, chances are your sodium intake is high. High sodium intake can be correlated to heightened BP. The Daily Recommended Value for sodium is 2400 mg which is 2.4 grams. A teaspoon is roughly 4.2 grams, pending what’s in the teaspoon, as “grams” refer to weight, and a teaspoon references volume. For example, a teaspoon of sugar weighs about 4.2 grams but the same teaspoon full of salt comes in at about 6 grams. Take a pair of dice. Set one aside, then cut the other in about half. Roughly, that is the portion size of your daily sodium intake. Tiny huh?
