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.

110317 Posture and the relationship to strength

110317 Posture and the relationship to strength

The display of strength is influenced by the joint angles of the operating links in the chain. These angles, as would be expected, change with movement. Because of this change, the length of the muscles varies throughout the movement, as does the angle of attachment to the bone.
This means the muscles ability to produce more, or less, force is determined by the angle as the leverages and “moment of muscular force changes the mechanical conditions of work.” This postural condition may benefit strength output if the “force potential of the muscles is used fully” but it can also be “hindrance when only part of their maximal tension can be used.”

Based strictly on observation it is clear that strength is affected either negatively or positively by various postural changes. As an example, most athletes are able to lift more weight in the dead lift than in a straight leg dead lift. This is a classic case of minor changes in the positioning of the links in the chain leading to tremendous strength advantages. In other words if the legs are bent and allowed to participate in the lift much more is hoisted up. It only stands to reason that the more muscles involved the more will be lifted.

Maximal force output at the working joints is truly dependent “upon the position of the system’s links relative to the proximal joints.” For example, the force developed in extension or flexion of the knee joint is determined by the angle at the hip joints. Thus, maximal force in hip extension in the seated position was found to be at an angle of 160° in the knee joint.

“In the leg press (lying on the back)” there was no difference “in knee extension force”…found at hip angles of 100° up to and including 140°’s. “Knee extension strength increases by 10%-12% if the torso is inclined 20° to 25° backward from the vertical with the subject seated in a rowing position. Thus, to produce maximal force in a movement, one must consider anatomical stability and ensure that at crucial moments posture enables the muscles to develop maximal external force.

Summary

Try different stances, different hand grips, and different joint angles during your lifts to increase your power output capacity. Just because Ed Coan or Fred Hatfield squats, a certain way does not mean it will be as effective or efficient for you to do likewise.

Postural changes, however slight, may make big differences in how much maximal force you are able to produce. Try it and see for yourself.

Final note: If you are considering a personal trainer or are training in a local health club, ask about the certification status of the staff. The qualified trainers will be happy to show you their credentials. Remember, it’s your money and more importantly your body, so go with the qualified instructors so you get correct guidance.

250217 Introduction to posture

250217 Introduction to posture

Posture is an important part of our lives. Posture counts. It can make us feel good or bad, not only mentally but also physically. Imagine walking around slumped over all the time, how do you think you feel? When you notice someone walking like this what is the first thing that pops into your mind? It’s probably something along these lines-they look like they are carrying the weight of the world on their shoulders.
Compare that posture to the posture you have when you really feel great. You can see it in how you walk down the street can’t you?
Carry yourself high and proud. Remember the old saying behavior changes attitude and vice versa. If you are slumping, do yourself a favor and perk up!

230117 General Upper Torso Stretches

230117 General Upper Torso Stretches

Shoulder front

Standing upright with good posture put your hands together behind your back, keeping your arms straight raise them slowly upward to the rear. Hold for a moment then lower back down and begin again.

Shoulder rear

Continue standing with good posture in an upright position. Take one arm and hold it horizontal and parallel to the ground. Now move it across your upper chest so the hand is on the opposite side. With the opposing hand hold the elbow of the horizontal arm and begin pulling in a gentle manner toward your chest. Hold the stretch for a moment and release then repeat.

Favorite shoulder stretch

Stand facing a wall with outstretched arms. Lean into the wall and rest on your hands now look between your arms and lower your head toward the floor. Feel the nice stretch in your shoulders. This can also be done by placing your fully extended arms onto a bench or chair and leaning downward toward the floor.

Floor stretch

Get on your hands and knees. While keeping your arms straight set back on your calves with your buttocks touching them. Put your head between your arms and touch the floor with your head.

Towel stretch

The old standby for working the shoulder range of motion is the towel stretch. Starting with a bath towel or dowel rod slung over your shoulder and dropping toward the floor hold the top with one hand the bottom with the other in your other hand. Now you can go one of two ways: either pull down with the back hand or pull up with the hand at the top. In both instances, the pull should be gentle as your shoulders are in a vulnerable position and easily damaged. A soft pull is what you are looking at achieving, just enough to stretch the shoulders. The ideal is to be able to touch your hands together in the middle of your back. This may be nearly impossible if you are heavily muscled.

Chest
In a standing position interlace your fingers on top of your head. Now move your elbows and hands to the rear.

Chest favorite

Standing next to the wall, a door frame or better yet a power rack, reach behind and hold onto the surface. The stretch begins as you turn your shoulders and upper torso away from the wall, door or power rack. This works really well with the power rack.

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.

031016 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.

220816 Healthy movement

220816 Healthy movement

Healthy movement is beneficial to your body and at its lowest level, even some activity is better than doing nothing. If you are just starting out then gradually build up your endurance with 5 to 10 minute exercise breaks throughout the day. At the 10-minute level, your body begins to adapt and then noticeable changes become evident.

After you are able to exercise aerobically for at least 10 minutes, it is time to branch out by adding resistance exercises to the daily routine. One way to begin is by doing one 10-minute session of endurance work and then later on in the day doing 10-minutes of resistance training.

Alternate between aerobic and resistance training for at least thirty minutes for the day.

The aerobic exercises can be brisk walking, skipping rope, riding a bike or any other activity that is continuous and places a demand on your breathing and heart rate. After you are finished then cool down with static stretches, holding each one for fifteen to thirty seconds. Do this three to five times for each stretch.

For the resistance training start out with body weight calisthenics by doing 3-5 sets of fifteen to thirty bodyweight squats, push ups, calf raises, prone back extensions, curl ups, leg raises or others of your choosing. You can do these in a circuit or one exercise at a time. Stay with it for the full 10 minutes.

If you are over sixty-five, the health benefits of activity are just as important to you as they are to the younger people. Start slowly and build up your fitness levels over time. If you have chronic health problems, work around them and do what you can.

If you aren’t able to ride a bike or have access to a treadmill or other such equipment, then get one of the hand ergometers available at Costco for about $49.00 and exercise your upper body. Do counter top pushups by standing two or three feet away from a counter top and then doing pushups on it.

Do chair sits. Sit in and stand up from a chair without pushing on your legs with your hands as you stand up. Practice sitting down on a chair; standing up, walking away briskly for 10 feet, and then coming back and sitting in the chair again. Repeat this for a minute or more. This builds up leg strength and helps with your balance.

Practice your balance to help prevent falls by walking sideways, standing heel to toe; practicing the stork stand on one leg with the other bent ninety degrees at the hip and knee or any of the many other balancing exercises.
