The study by doctors in Seattle also noted that insulin resistant people with excess abdominal fat also appeared to show higher concentrations of a substance known as apolipoprotein B (apoB) and lower levels of high-density lipoprotein (HDL) cholesterol, a “good” form of cholesterol. Previous studies have suggested that high levels of apoB may encourage the development of arteriosclerosis.

Study author Dr. Steven E. Kahn of the VA Puget Sound Health Care System in Seattle, Washington, states that he and his colleagues suspect that a potbelly likely precedes insulin resistance. Once both conditions have set in, he noted, people’s bodies are more likely to be primed to develop arteriosclerosis.”We think that the deposition of fat in the inside of the abdomen is the critical determinant of insulin resistance in the general population,” Kahn said. “We think that the fat begets the insulin resistance, which helps produce” risk factors for arteriosclerosis, he added.

Kahn’s is not the first study to identify health hazards of potbellies. Although body fat tends to relocate to the abdomen with age, past research has shown that excess belly fat, compared to fat elsewhere on the body, can increase the risk of heart disease and type 2 diabetes, as well as up the chances of stroke in middle age.

In the current study, Kahn and his colleagues measured body fat distribution and screened for insulin resistance in 196 people. The authors also determined how much choesterol, fat, and apoB was present in each participant’s blood.

The average age of study participants was 53. They were all seemingly healthy, with no history of diabetes or cardiovascular disease.

Reporting in the January issue of Diabetes, Kahn and his colleagues discovered that people with bigger potbellies who were more resistant to insulin also had lower levels of HDL cholesterol and higher levels of low-density lipoprotein (LDL) cholesterol–the “bad” form of cholesterol.

Risk factors for arteriosclerosis appeared to be linked more strongly to tummy size than to whether a person had insulin resistance, Kahn and his team note.

The current study findings suggest that even people who are not obese can be at risk of arteriosclerosis, the authors note. Seemingly slim people can carry excess tummy fat and be resistant to insulin, they write, and can therefore be at risk for the blood vessel disease.

In an interview, Kahn noted that abdominal fat could play an essential role in people’s risk of future disease. Specifically, he said having a pot belly “is a critical component of metabolic syndrome,” a condition marked by insulin resistance and high blood pressure, and which often precedes diabetes and cardiovascular disease.

According to recent research, those who have a large potbelly appear to have a higher risk of arteriosclerosis. This is the medical term for the fatty buildup on the lining of arteries that researchers now believe increases the risk of heart attack and stroke. SOURCE: Diabetes 2003;52:172-179

People who carried this “spare tire” of fat around their waists are more likely to have increased fat and cholesterol in their blood.

The study by doctors in Seattle also noted that insulin resistant people with excess abdominal fat also appeared to show higher concentrations of a substance known as apolipoprotein B (apoB) and lower levels of high-density lipoprotein (HDL) cholesterol, a “good” form of cholesterol. Previous studies have suggested that high levels of apoB may encourage the development of arteriosclerosis.

200317 Fluid replacement-Water and the body-why we need it 

In the book Essentials of Strength Training and Conditioning (page 247), it states that a fluid loss of around 1% of body weight will increase core temperature with a disproportionate rise in heart rate. These increases in temperature causes further fluid loss and the cycle repeats itself.

Plasma volume becomes reduced when sweating causes a fluid loss of 2-3% body mass. The blood thickens, which makes the heart work harder at pumping it through out the body. As dehydration progresses and plasma volume decreases, peripheral blood flow and sweating rate are reduced and thermo regulation becomes progressively more difficult. (Page 509 reference #1)

A 5% dehydration of the body mass significantly increases rectal temperature and decreases sweating rate. There is 25-30% decrease in stroke volume from the heart that is not off set by a higher heart rate so the system output and arterial blood pressure decline. For each liter of sweat loss, the heart rate increases by about eight beats per minute, with a corresponding decrease in cardiac output. “The primary aim of fluid replacement is to maintain plasma volume so that circulation and sweating progress at optimal levels”.

In Essentials of Strength and Conditioning, it (page 247) states that at 7% body weight loss a collapse is likely. Obviously, this is a serious condition if left unchecked.

Ultimately, the strain on the circulatory system impairs the thermo regulation of the body. (Page 507 reference #1)

Thirst is not a good indicator of hydration level as it normally lags behind the body’s needs. Each adult requires from 2-3 quarts of water/fluid daily, less than that, will gradually result in a dehydrated state over a period.

Indicators of the need for more fluid in the body that are relatively simple to monitor are (Page 247 reference #2)

  • Dark yellow urine (unless excessive vitamin intake has occurred)
  • Strong smelling urine
  • Decrease times of having to urinate
  • A rapid resting heart rate
  • Muscle soreness that lingers longer than normal

Normal urine loss for an adult is about 4 times per day for a total of about 1.2 quarts. This means the elimination of 8-10 fluid ounces about 4 times per day. If a person is drinking over and above the normal requirements bathroom breaks could occur more often. If this is not the case, and you are not drinking excessively, perhaps a check for diabetes is in order.

291016 Reasons to exercise

291016 Reasons to exercise

The benefits of regular exercise are well known in today’s society. It has been consistently demonstrated that it leads to a healthier more productive life. Being active lowers your risk of developing heart disease, adult on set diabetes, sometimes referred to as type 2 diabetes, and osteoporosis. It’s not only these benefits that result from exercise, others fall into place as well.

Those who are regular participants in moderate to vigorous activities have the ability to deal with the stresses of daily life and are less likely than non-exercisers to suffer from anxiety and depression. Longevity has a direct correlation to being active. The more active you are throughout your life the greater your chances of staying healthy and living a longer life.

Following a plan of regular exercise and eating healthy foods and fluids can lower the actuary[1] predictors of coronary heart disease and stroke. Exercising regularly often times means your critical health numbers will become lower. These numbers include your blood pressure, body weight, fat composition, blood triglyceride levels, and low-density lipoproteins (LDH).

The numbers indicating good cholesterol (HDL) rise with good exercise and a healthy diet.

Blood sugar tolerance, also known as glucose tolerance, is the ability of your body to regulate the level of sugar circulating in the blood. When this tolerance becomes lower, the amount of sugar in your blood becomes higher, which may lead to diabetes. Currently, about one in four older adults are at risk of developing type-2 diabetes in the US. The studies are clear in their findings: physically active people are less likely to develop this disease then those who are sedentary. Exercise improves the ability of the body to use insulin, which is a hormone that regulates the amount of sugar in the blood. This process maintains the blood sugar at the recommended levels.

The benefits of exercise far outweigh the time spent working out. Just of few of the reasons to exercise, include stronger bones and better mental health.

Improved bone density

Osteoporosis, a disease where the bones become fragile and fracture easily, is of concern to many older adults. This affects more women than men even though men still suffer from the disease.

Once osteoporosis has progressed to a dangerous level, even a small slip and fall can cause a broken bone, especially in the hips and wrists of a female.

Weight bearing exercise has been well documented in both medical and scientific literature to be of value in strengthening the skeletal bones. Strength training and impact exercises have a direct positive relationship to building stronger bones, particularly the long bones in the body. These types of exercises can help prevent further skeletal bone loss in those with osteoporosis.

Mental well-being is enhanced when you exercise. The release of natural chemicals into your body helps improve your outlook on life. They make the minor momentary pain of exercise feel good all day long. That’s not all there is to the role of activity and exercise in making your life batter. An added outcome of regular exercise is the ability to control your weight.

Less body weight means less stress and trauma on your lower torso joints, i.e. the hips, knees and ankles. It makes sense that the more you weigh the more these joints have to work to stay healthy. Too much bodyweight can damage the cartilage, which in turn fosters the onset of arthritis and osteoarthritis and leads to joint implants.

Remember you will never exercise your way to more lean muscle mass through a high calorie diet. Eating or drinking too many calories will not be exercised away, contrary to what the machines are telling you about the caloric expenditure for X-amount of time on them.

241016 It is never too late to strength train

241016 It is never too late to strength train

There are numerous studies showing that people who do resistance training have significantly improved their muscle strength and performance. These changes show up in as little as two months. This held true even with the frail and over age 80 population. Not only does resistance training improve strength it can also help prevent and treat sarcopenia.

According to an analysis conducted in 2010 by the Aging and Research Reviews, strenuous, intense workouts are the most effective. You can bet they did not use soup cans in these intense workouts. However, if you are seriously out of condition you probably will have to start out gradually. Find a qualified strength trainer, one with good credentials from a nationally recognized association, and get started.

In order to help prevent or treat sarcopenia, strength train regularly and make sure that you are getting enough protein and your system on a daily basis.

A basic strength program stressing the major muscle groups, consisting of three sets of eight repetitions, performed 2 to 3 times a week will show increases in strength and functionality within a short period. These targeted muscle groups should involve the shoulders, arms, upper back, chest, abdominals, lower back, the quads and hamstrings of the legs and the calves.

Begin with a warm-up with some sort of an aerobic exercise to the point where you are breathing heavier, your pulse is going faster and you have a slight sweat. Now it is time to start lifting.

Begin with the weight that you can handle 10 to 12 times. In over the course of a week or so add weight until the last two repetitions of the set are difficult. Rest 2 minutes and repeat the exercise set again. If you’re able to complete three sets of eight repetitions with a specific weight then that weight is to light and more needs to be added to the bar.

On the days that you are not strength training, do some sort of aerobic exercise for 20 to 30 minutes. Keep track of what you’re doing. You are going to notice improvements in your strength level and in your ability to move a lot easier in your daily life.

270816 An introduction into strength and power training for all ages

270816 An introduction into strength and power training for all ages

It turns out there are effective actions you can do to positively alter your health. They can help improve your blood sugar and cholesterol levels, help improve your mood, make you stronger and more powerful, and at the same time make your bones stronger to help ward off fractures.

These are not the only benefits these actions, not by a long shot.

They can potentially help you avoid disability, frailty and retain that precious independence we all want to have as we age.

Strength training can do all of this.

It is a well-known fact that strength training offers all of the benefits previously mentioned, in addition to many others such as are listed in the following section from the Harvard Medical School.

“Practically any regular exercise benefits your health. Strength training specifically helps in the following ways:

  • Strengthens muscles
  • Strengthens bones
  • Prevents falls and fractures by improving balance and preserving power to correct missteps
  • Helps to control blood sugar
  • Relieves some of the load carried by the heart
  • Improves cholesterol levels
  • Improves the body’s ability to pluck oxygen and nutrients from the blood stream
  • Boosts metabolism even while sleeping  and thus helps keep weight within a healthy range
  • Prevents or eases lower back pain
  • Relieves arthritis pain and expands limited range of motion
  • Raises confidence , brightens mood, and helps fight mild to moderate depression
  • Wards off loss of independence by keeping muscles strong enough for routine tasks”

According to the Center for Disease Control (CDC) there is now a heightened awareness of the benefits of strength training. There is also the fact that only a small percentage of the American population have actually started a strength training program. This percentage is estimated at just slightly under 22% for men and 18% of the women in our nation who are strength training twice a week on a regular basis.

This percentage figure is way below the U.S. governments Healthy People 2010 goal of 30% of the adults in America who make strength training a part of their exercise program.

If you’ve never lifted weights before or done any type of resistance training the biggest barrier to starting may be knowing where to begin. This may be your situation, if so all you need to start is a comfortable pair of shoes and clothing. Adding to this, a solidly built chair, a few dumbbells and if you’re able to skip rope, a skip rope. This is all you need to get started. There, that wasn’t so difficult was it?

Since the health benefits of strength training are founded on its ability to protect against the onslaught of frailty, while at the same time making everyday tasks easier and more manageable it is essential that you begin sooner rather than later. The longer you wait the more your muscle tissue, bone density, and strength dwindle. If you don’t do something about your strength and power abilities you will soon find it difficult to walk upstairs, get up from a chair, carry groceries, and fend for yourself as an independent person.

Not only will you find it difficult to do the aforementioned tasks but also lacking strength leads to falls and that can mean incapacitating fractures. This in turn further compromises your ability to lead an active life. Strength training has a wealth of research backing its ability to effectively slow down and possibly reverse these life altering events.

Even if you are in your 70s, 80s, 90s and above, research has shown a dramatic increase in strength, power, agility, and mobility within 10 weeks of lifting weights 2 to 3 times a week. Now you have to admit that this is not a tremendous time commitment, especially considering the benefits to your health.

240816 Eat your Raspberries

Eat your Raspberries

In a review of scientific literature, published in the January 2016 issue of Advances in Nutrition the conclusion is “Raspberries have a number of heart and brain-health protective essential nutrients.”[1]

It seems as though Raspberries contain anti-inflammatory, anti-oxidative and metabolic stabilizing activity. All of which are good news to those of us interested in maintaining our health.

Raspberries also have anthocyanins, a known inflammation suppressant. Additional benefits accrue from the high amounts of polyphenol in the berries. Polyphenol may help in preventing platelet buildup and reduce blood pressure too.

There is further good news for those with diabetes; “Raspberries have potential to help reduce factors contributing to metabolic syndrome, which has implications for diabetes development and overall cardiovascular and brain health” says lead author Britt M. Burton-Freeman, PhD, MS, Institute for Food Safety and Health, Illinois Institute of technology.”[2]

150816 The metabolic syndrome and what it means to your health

150816 The metabolic syndrome and what it means to your health

The metabolic syndrome is the name given by the medical profession to a group of health risks having a strong potential to increase the risk of diabetes and heart disease. These unhealthy conditions are for the most part avoidable simply by eating less and getting more exercise.

The five components of the syndrome are:

  • A waist that is larger than 35 inches in women and 40 inches in men. Some men may be at risk even if their waist is greater than 37-39 inches.
  • Low cholesterol readings of the good HDL. Women should have numbers under 50 and men should have their numbers under 40.

Higher than normal, but not necessarily high numbers in the following categories:

  • Systolic blood pressure of 130 or higher and a diastolic reading of 85 or higher.
  • Fasting blood sugar count of 110 or higher
  • Tested triglycerides of 150 or above after fasting.

According to the doctors, a person with three or more of these five categories raises their risk of becoming diabetic and developing heart disease.

The research specialists believe the root cause of this syndrome is an inefficient insulin response.

The metabolic syndrome is the consequence of our body being ineffective in processing fats and sugars. The research shows that belly fat creates increased inflammation and a greater risk of heart disease in those with big bellies. These fat cells also release a product that can drive up blood pressure by reducing the blood vessels ability to relax between strokes. Additional problems with belly fat cells occur because they generate proteins that increase the process of insulin resistance.

In case you are wondering what the term insulin resistance means here is a brief explanation.

The hormone insulin makes it possible to remove glucose, also known as blood sugar, from the blood stream and put into the muscle tissues. The muscle uses this as energy for movement. If too much glucose is in the blood stream it is stored as fat. Therefore, the term insulin resistance means the body is having a hard time delivering the glucose to the muscle tissues (insulin resistance) so the amount of blood sugar rises in the blood stream.

The cause is the waist is too big! Our bellies are too fat, too large, too much over the belt, hanging out too far, you can call it whatever you want to, but the fact remains we are a nation of too much fat. And it is all in the wrong place.

060616 Getting the most from your breathing (1/3)

Getting the most from your breathing 

Breathing, as we all know is an important function of life. It is just as important knowing how to breathe or not breathe, while lifting. Surfing through the internet will be a roller coaster ride if you are looking for helpful directions in the proper way to breathe. Some say, in fact most are saying to breathe out as you lift the weight. Unless there is a medical reason for breathing out as you enter the concentric phase of the lift don’t do it.

Breathing out works as long as the weight is light, insignificant, and puny because your body doesn’t need to stabilize itself as much. However, once the load increases up to a level that will make a difference in your strength levels, you will automatically hold your breath near to, at, and through the sticking point. Try and see for yourself.

Now I am not so naïve as to think some of you will not force yourself to consciously breathe, during the heaviest part of the lift just to show that you can do it. However, if you (or your partner if you have one) are truly paying attention to your breathing patterns, you will notice that you hold your breath during the heaviest part of the lift.

This is similar to trying to achieve muscle isolation; with light weights it may work. But once again, with heavier weights your body will reach out for assistance from surrounding muscles to complete the lift. The body does what it has to do to complete a task, whether it be recruiting other muscles or breathing adjustments.

Regarding breathing, you can make these adjustments to enhance your ability to move heavier weight. It will take a conscious effort on your part to successfully change a previous non-helpful habit such as forcing yourself to breathe out throughout the concentric portion of the heaviest part of the lift.

Instead, some coaches disregard the prebreathing phase altogether and recommend using a modified version of the Valsalva maneuver throughout the lift[1]. As previously stated, you will automatically hold your breath during the heaviest part of the lift—this is normal. What is not normal is using it throughout the entirety of the lift. Problems may arise when using the Valsalva maneuver.

[1] Valsalva Maneuver

The Valsalva maneuver is performed by attempting to forcibly exhale while keeping the mouth and nose closed.

 

290516 Knowing your numbers – blood pressure

290516 Knowing your numbers – blood pressure

High blood pressure is commonly referred to as the silent killer because unless it is extremely high there are no outward symptoms or signs.

High blood pressure is a contributing factor to:

  • Strokes
    • Very high pressure can cause a break in a weakened blood vessel, which then bleeds into the brain. This can cause a stroke. If a blood clot blocks one of the narrowed arteries, it can also cause a stroke.
  • Eyes
    • Continuous or high blood pressure can in time cause blood vessels in the eye(s) to burst or bleed. Your vision may become blurred or otherwise impaired. This can result in blindness.
  • Arteries
    • As people age, the arteries throughout the body harden, particularly those in the heart, brain, and kidneys. High blood pressure is associated with and is a direct contributor to these stiffer arteries. This in turn, causes both the heart and kidneys to work harder to do their job of keeping the body healthy.
  • Kidney
    • The job of the kidneys is to act as filters to rid the body of wastes. Over time, high blood pressure can narrow and thicken the blood vessels of the kidneys. Once this happens the kidneys filter less fluid. This causes waste to build up in the blood. At this point, the kidneys may fail altogether. When this happens, medical intervention is necessary and treatment in the way of dialysis or a kidney transplant are distinct possibilities.
  • Heart
    • A major risk factor for heart attack is high blood pressure. Throughout the body, the arteries bring oxygen-enriched blood to the heart muscle. Without enough oxygen in the heart, chest pain, known as angina, can occur. If this blood flow back to the heart is blocked, a heart attack results.
  • Congestive Heart Failure
    • High blood pressure is the number one risk factor for congestive heart failure (CHF). CHF is a serious condition in which the heart is unable to pump enough blood to supply the body’s needs.

Therefore, it’s important to know whether not you have high blood pressure. And the only way you know this is to have your blood pressure checked.

Blood pressure is both measured, and displayed with two numbers. The first number is a systolic this is the highest pressure in the arteries when your heart beats. The second number is the diastolic pressure. This, the lowest number, is when your heart is resting between strokes.

The ideal blood pressure is under 120 over 80. Anything above these two numbers is either pre-hypertension or hypertension. A blood pressure level of 140/90 mmHg or higher is considered high blood pressure. About two-thirds of people over the age of 65 have high blood pressure.

If you have had your blood pressure checked and it is between 120/80 mmHg and 139/89 mmHg, then you have prehypertension.
