Holding tension in any position that does not have dynamic movement is isometric exercise. The British Journal of Sports Medicine has a study with research that shows this isometric exercise done with squatting on the wall (or with a ball against the wall) for support for 2 minutes repeated 4 times with rest periods of two minutes each time for total 4 wall sits, taking 14 minutes, can reduce systolic blood pressure top number by 10 mmHg and diastolic pressure by 5 mmHg. Jamie O'Driscoll the lead author of the study says this is useful for people doing aerobic exercise, and yet could benefit from the use of isometric wall squats. A clinical exercise physiologist at University of Michigan says isometric exercise works because contracting a muscle and holding that position reduces blood flow to that muscle, when you release blood flow increases to muscle tissue. It creates signals that tell blood vessels to relax more and create less resistance to blood flow. To do this wall sit find a wall to lean against and take a couple of steps forward, feet hip width apart and slide your back down the wall and your knees getting to a 90 degree angle gradually. This uses quadriceps, glutes, calves, all leg muscles and abdominal muscles. ...

Dr. Nancy Krieger of the Harvard School of Public Health says data on health risk -including which counties have high rates of health conditions such as obesity and other diseases- should inform targeted interventions and public messaging. This is important for administrators and health authorites in each county and state as they deal with a surge in coronavirus in parts of the U.S. which have so far been only slightly affected such as rural southern and western states. More recently places such as North Dakoa which the virus missed in the early stages are now seeing a jump in cases. This report shows counties in states such as Tennessee, Georgia, Alabama, Mississippi, North Carolina, particularly susceptible because of high rates of obesity and other health conditions. In all almost half of the U.S. population has one of these health conditions- obesity, diabetes, high blood pressure, lung disease and heart disease.  The high prevalence of obesity which worsens all other health conditions is a result of the lack of healthy food and nutrition, exercize and healthy living habits, that were neglected in the closing decades of the twentieth and early twenty first century. The shift to processed foods is only one of many bad practices that happened in these years. The lack of attention to healthy eating and nutrition, and outdoor exercize has marked this period and created conditions in which the virus could damage health. ...

Comparative effectiveness research will be conducted to evaluate what is the best treatment for any ailment or disease or health problem under the $1.1 billion allocated for this in the Stimulus Plan. What are the alternative methods of treatment, what is the effectiveness of each treatment, what are the comparative costs and so on. Is it better to treat neck pain with surgery or acombination ofphysical therapy, exercize and medications? If there is ablockage of arteries in the lower leg and leg pain, how does drugs and watchful waiting compare with surgery? For chronic heart failure how does home monitoring of blood pressure and weight and exercise in addition to medications provide an alternative route as opposed to just medications. Dr Fisher of Dartmouth Medical School cites these as examples of questions that can be asked in comparitive effectiveness research. The money will be available to the Health and Human Services Department and will be used over several years. About 15 federal employees will form a council to coordinate the research and advise President Obama and Congress on how to use the money. In 2007 the US spent $2.2 trillion, or 16% of GDP, on health care, and the Congressional Budget Office says it will grow to 25% of GDP at the rate its growing by 2025 if left to its own devices. ...
