Prehypertension and Risk of Stroke
A recent report has implicated Prehypertension – Systolic between 120-139/Diastolic between 80-89 – independently raises the risk for stroke by about 50%, according to results of a new review of relevant research.
“Importantly,” the authors say, the risk for stroke appeared more strongly driven by higher systolic or diastolic BP values within the prehypertensive range.
It’s appropriate to “recommend and monitor therapeutic lifestyle changes” in patients who have a BP that falls within the higher range of prehypertension (ie, systolic BP, 130 – 139 mm Hg; or diastolic BP, 85 – 89 mm Hg), first author Bruce Ovbiagele, MD, from the University of California, San Diego, told Medscape Medical News.
In most studies reviewed, baseline BP was obtained by a single-day measurement, which may lead to misclassification of BP levels and a dilution bias, the authors note. In contrast, previous epidemiologic evidence suggests that BP measurements taken on a single day may be adequate, they point out.
However, a single-day measurement is not sufficient to characterize BP variability, and data on BP variability were not available in the studies analyzed.
Despite these and other potential limitations, “the results of this systematic review probably represent the most precise and accurate estimate of the strength of the relation between prehypertension and incident stroke currently available,” the authors conclude.
On the basis of their findings, they suggest that randomized trials to evaluate the efficacy of lowering BP levels in those with higher values within the prehypertension range are warranted.

Adjustments to Common Shoulder Exercise
For gym goers looking to build strength and fill out their T-shirts, poor form or technique can turn shoulder workouts into a fast track to physical therapy.
About a third of all resistance training injuries involve the deltoids, the muscles that form the rounded contour of the shoulder, making them one of the most common injuries that occur in the weight room.
But many of these injuries can be prevented with small changes in technique, a fact highlighted by new research published in the latest issue of Strength & Conditioning Journal.
The research focuses on one of the most popular shoulder exercises for men and women: the upright row.
The study found that three simple steps can reduce the risk of injury.
“You increase the chances of impingement when you bring your elbows up beyond 90 degrees — basically when they’re past parallel to your shoulders.”
The same rule holds for another popular exercise called the lateral raise, which develops the medial deltoids. Exercising the medial deltoids carries a number of aesthetic and practical benefits. The exercises can also build strength for everyday activities like carrying groceries, lifting heavy objects or hoisting small children.
COTs HealthBeat recommends discussing all Exercise routines and questions with your Qualified Health Care Provider.

Exercise and Insulin Resistance
Insulin Resistance is a growing problem in the United States.
People with insulin resistance, also known as impaired insulin sensitivity, have built up a tolerance to insulin, making the hormone less effective. As a result, more insulin is needed to persuade fat and muscle cells to take up glucose and the liver to continue to store it.
Normally, food is absorbed into the bloodstream in the form of sugars such as glucose and other basic substances. The increase in sugar in the bloodstream signals the pancreas (an organ located behind the stomach) to increase the secretion of a hormone called insulin. This hormone attaches to cells, removing sugar from the bloodstream so that it can be used for energy.
In insulin resistance, the body’s cells have a diminished ability to respond to the action of the insulin hormone. To compensate for the insulin resistance, the pancreas secretes more insulin.
Over time people with insulin resistance can develop high sugars or diabetes as the high insulin levels can no longer compensate for elevated sugars.
A recent study published in the journal Strength and Conditioning, found that Exercise is an effective treatment in the management of Insulin Resistance through:
• Enhanced Insulin Sensitivity
• Increased Skeletal Muscle Glucose Uptake
• Improved B-Cell function
Additionally, Exercise may positively modify comorbidities often associated with Insulin Resistance.
