Vascular disease is one of the most common causes of death worldwide, and for many people prolonged sitting is a contributing factor, but there is a way to reverse vascular dysfunction if you have a sedentary lifestyle.
Vascular health focuses on keeping your heart and lungs in good condition so they can perform at a strong level. As we age we are at a higher risk for heart attacks, high blood pressure, high cholesterol, strokes and peripheral artery disease (P.A.D). When we live sedentary lifestyles we are putting ourselves at even more risk of vascular dysfunction.
Our weight plays a big part in many of our health problems, including the diseases mentioned above. Most people associate exercise with good cardiovascular health, but they don’t realize what physical activity, like walking, can do to keep our blood pressure and other diseases from taking over.
Cardio exercises, such as running, swimming and cycling, can help get our heat rate up and are excellent for both the vascular and respirator systems. While not all of us consider ourselves athletes, it doesn’t mean we have to give up and turn to a life of sedentary sitting. A new study suggests that simply walking around for a few minutes can reverse vascular dysfunction caused by sedentary sitting.
Technology – specifically sitting at a computer – has increased sedentary behavior in recent years, thus raising concerns about vascular health. Researchers from the University of Missouri School of Medicine decided to look at the problem. What they found was that when a person sits for six hours straight, vascular function is damaged; however, walking for just 10 minutes after sitting can help restore vascular health.
During the study, researchers observed and compared the vascular function of healthy men before and after a long period of sitting. They discovered that blood flow in the popliteal, an artery in the lower leg, was significantly reduced after sitting at the desk for just six hours. Once the participants took a 10-minute walk, their blood flow and overall vascular function improved.
Fitness experts at the University of Missouri explained that when you have decreased blood flow, the friction of flowing blood on the artery wall is also reduced. It seems that moderate levels of friction are good for arterial health, but low levels reduce the ability of the artery to dilate. The more the artery can dilate, the healthier it is.
The research team has indicated that more investigation is needed to figure out if repeated periods of reduced vascular function with prolonged periods of sitting can lead to long-term vascular problems.
The first step to protecting yourself from cardiovascular disease and other vascular diseases is to avoid unhealthy habits, such as a poor diet and smoking. The next step is to get moving. While a walk is great to get the blood flowing and awaken the senses, there are many other exercises you can enjoy while also being kind to those vascular blood vessels.
Cardio exercises can normally get your heart rate up to between 65 and 95 percent of its maximum. The list below includes a few examples of cardio exercises that you can consider.
If you are not accustomed to cardio exercises, it is best to start out slow, gradually increasing your exercise level. This will help build strength in your heart and lungs.
Perhaps you are trying to prevent heart attacks, peripheral artery disease, high blood pressure, or you have a disease and want to improve your situation; regardless of the circumstances, there are other ways aside from cardio exercises to go about it.
You can eat a diet low in cholesterol and saturated fat to make sure plaque does not build up in your arteries. Plaque slows, and in some cases even stops, blood flow to and from your blood vessels. At the same time, you can be monitoring your blood pressure since high pressure puts your cardiovascular health in jeopardy. If you have diabetes, work on keeping your blood glucose under control. People with diabetes or peripheral arterial disease should also pay close attention to foot care. Blood vessels in your limbs are more prone to hardening of the arteries, as well as nerve damage.
One of the best things we can do for our vascular health is maintain an optimum weight. After all, for every pound we have on us, our heart has to pump blood through an extra mile worth of blood vessels.
In the late 20th century, medical and labor experts recognized that musculoskeletal problems were linked to long periods of time working at the computer. This led to ergonomic guidelines. It has only been in the last few years that the issue of sedentary sitting and lowering the risk of disease has been seriously examined.
In an attempt to find workplace solutions for sedentary sitting, Australian researchers applied three different strategies to three separate government offices, to see if they could impact the health risks associated with sitting.
Here is how the study was laid out – there was one organization, where workers could manage their own time and workflow, another organization where there was little flexibility in the schedule, and the third office where time was strictly controlled. The three different strategies were applied: active work desk with either a treadmill or biking desk that had a computer and phone access; light to moderate activities before and after work, as well as taking active breaks during work; and active sitting and moving around while still sitting, as well as breaking up computer tasks.
The results showed that none of the three strategies were better than the others. Overall, there was about an eight-minute reduction in sedentary time. There were slightly greater reductions in sedentary time and increased active time in the organization that had the most flexibility in schedule.
The authors of the study realize the results of their experiment are not earth shattering, but they believe that setting guidelines to reduce sedentary behavior for workers is way overdue.
Some offices have taken steps to help their employees maintain or improve their health. The fitness center at IBM Canada’s office in Markham, Ontario is a popular amenity. According to Human Resource officials within the company, the fitness center has become a “key selling point” for recruiting new talent. About 40 percent of their work force uses the facility.
A federally funded study in Canada showed that fitness opportunities at work, like the IBM fitness center, significantly reduce work absenteeism due to health issues.
Chesapeake Energy Corp in Oklahoma City has what many people refer to as the “granddaddy” of fitness centers – a 72,000-square foot gym. They take their wellness program to a whole new level by offering their employees cash incentives to meet various fitness goals.
While not all employers can afford to provide their workers with grand fitness programs, they can’t afford to ignore their health completely either. Poor health is a high price to pay for both employee and employer in the long run.
