180417 Osteoporosis: The risk factors

180417 Osteoporosis: The risk factors

Some risk factors are under your control whereas others are not. Here is a brief list for your consideration.

1. Gender-of the ten million people with osteoporosis in the United States 80% of these are women. Particularly affected, and at increased risk for the disease, are Caucasian and Asian women.

2. As you grow older your risk increases.

3. Your diet and health history habits make contributions to the disease. Drinking alcohol and smoking, along with a lack of calcium and vitamin D and exercise hasten the onset of this bone weakening condition.

4. Other health conditions such as hyperthyroidism, chronic kidney disease and rheumatoid arthritis seem to predispose a person to osteoporosis.

5. Medications such as thyroid medication and oral steroids can damage the bones.

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.

010417 Recovery methods employed after heavy exercise. (2/2)

010417 Recovery methods employed after heavy exercise.

By Danny M. O’Dell, M.A.CSCS*D

Let us briefly discuss a few of these and the way in which they are applied during the recovery process. Use these various modalities between sets or between days of training. Experiment until you have found the ones that work best for you.

Use of the various means of recovery should be included as a part of the over all design package of your work out plan. You will find some that fit you very well, just as some exercise seem to be tailor made especially for you. However, keep varying the different modalities, as your body will soon accustom itself to those, which are applied most frequently. The benefits will diminish if they are over used. The bottom line on the issue is this: just as you change your exercise selections around each training day so must you change your recovery modes around.

The most intensive recovery methods are utilized after the heaviest workouts. Apply the recovery modes not just directly after the workout, but later in the day after your body has adjusted to the stress of the training session. Wait at least three hours before starting the recovery process. If you wait 6-9 hours, the recovery is made much more effective and will raise the work capacity higher the next day.

130317 Posture-dynamic and static

130317 Posture-dynamic and static

Posture, just the word brings to mind standing at attention with your head up, shoulders back and chest out. In reality it is more than this.

Body posture is both dynamic and at the same time a static action. In fact balance and posture are closely intertwined and in many cases are the same.

Posture affects not only how tall you will grow and how well your internal organs function but your activity and sports performance as well.

Briefly stated, posture can cause positive or negative alterations in the structure of your bones. Problems with your posture cause muscle imbalances, flexibility issues and damage to your joints if continued long term. The results of these changes are back, shoulder and neck pain, all of which, if caused by poor posture, can be alleviated with a conscious awareness of maintaining good posture.

Early on in a person’s life when the body is still developing is the ideal time to establish good posture habits. Doing so allows the body to build a strong useful platform for daily activities and participation in sports.

Good posture means your internal organs have room to grow and be healthy. Improper alignment in the structures of your body puts undue stress on the rest of it causing chronic strain which translates into chronic pain. Some study results have associated chronic pain as being a contributing factor to arthritis later in life.

The spinal column is the supporting base for your entire body and as such needs to be strong and powerful to endure the stresses placed on it throughout the day and for the remainder of your life.

The spine should be solid and flexible (within normal range of motion) while at the same time maintaining the four natural curves at all times. Strengthening the spinal column and the muscles that attach to it will help keep your posture correct and you feeling good about yourself.

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.

060317 Shoulder posture

060317 Shoulder posture

An ideal alignment will have the line of reference passing midway through the shoulder joint as it travels downward. The arm and shoulder position depends on where the scapulae and upper back positions are. In a normal, i.e. correct alignment, the scapulae will be lying flat against the upper back. This position is roughly located between the second and seventh thoracic vertebrae with about four inches separation. Even this separation depends on the size of the person.

Positions of the scapulae, other than that described, will negatively affect the position of the shoulder. This particular misalignment of the Glenohumeral joint will in many cases set the athlete up for an impending injury.

040317 Checking your posture

Did you notice irregularities in symmetry from side to side? Perhaps you have one shoulder lower or one hip higher than the other, maybe there is more space between one arm and the body compared to the opposite side. Do your knees turn in or out? If you answered yes to any of these, then here is a short self-check for you to examine your posture a bit closer.

Stand with your back to a wall, your heels about 6 inches from the wall. Place one hand behind your neck, with the back of that hand against the wall. Place the other hand behind your lower back, with the palm against the wall. If there’s enough space between your body and the wall to move your hands forward and back more than an inch the curves in your spine may not be in proper alignment.

If you found your posture lacking a bit here are three posture practices that just may help.

This exercise is a demonstration of correct standing posture. Try practicing it two to three times a day.

  1. Stand with your back against a wall. Place your heels about 6 inches from the wall and about 6 inches apart from each other. Keep your weight evenly distributed. Arms are relaxed at your sides. Keep your ankles straight, your feet pointed straight ahead and your kneecaps facing front.

    2. Bring your head back to touch the wall. Tuck your chin as if a string were attached to the middle of the back of your head; pretend the string is being pulled up. Pull up and in with the muscles of the lower abdomen, trying to flatten the stomach and bringing your lower back closer to the wall. Gently straighten your upper back by lifting your chest and bringing your shoulders down against the wall.

    3. Hold this position for 10 seconds, breathing normally. Relax and repeat three to four more times.

This exercise is a demonstration of correct sitting posture. Try practicing it two to three times a day.

  1. Sit in a straight back chair, with both feet flat on the floor and with your back resting against the chair. Arms are relaxed with hands on your lap or on armrests. Hold your head erect. Tuck your chin in as if a string were attached to the middle of the back of the head; pretend the string is being pulled up.

    2. Pull up and in with the muscles of the lower abdomen, trying to flatten the stomach. Gently straighten the upper back, lifting the chest. Bring the shoulders back and down against the chair.

    3. Hold this position for 10 seconds, breathing normally and keeping the rest of the body relaxed. Relax and repeat three to four more times.

One final practice is also the most old fashioned. Simply balance a small pillow or book on your head as you go about your normal activities such as walking, working or doing the dishes.

Lastly, as you lay in your bed try placing a small pillow under your knees if lying on your back or between your knees if you sleep on your side. Both practices help keep your spine aligned correctly.

270217 Checking your posture

While viewing an individual from the side, imagine a plumb line dropping from the middle of the ear downward to the floor. From the ear, the line will continue through the middle of the shoulder, down through the hips, mid knee and onto the ankles. Viewed from the rear this same line will be seen dropping from the middle of the head, middle of the back through the Gluteal cleft and between the knees and ankles to the floor.

This line divides the body into the front and rear sections with equal weight on both sides. This dividing line makes no effort to be symmetrical nor is it passing through any obvious anatomical structures equally.

Poor posture can contribute to low back pain, shoulder joint pain, and can even affect how you walk (your gait). If left unattended this pain could become chronic in nature and in a worse case situation could cause long-term damage to the body. This column will include suggestions to improve standing, sitting and lying-down posture.

But first off do you have proper posture? A quick check may offer a revealing glance at how you carry yourself day in and day out.

Begin by standing in front of a full-length mirror. Do you look even from side to side, are your shoulder’s straight across with both sides on the same level as the other side, i.e. one is not higher or drooping when compared to the other side. Imagine a straight-line beginning from the middle of your head through your nose, through the middle of your breastbone, down between your knees and feet. The spaces between your arms and sides are equal, your hips are level, your kneecaps face straight ahead, and your ankles and feet are straight.

Now stand sideways to the mirror and check that an imaginary line beginning at your ear lobe continues down your body. As it drops down it should be hitting the middle of your shoulder. It should pass just behind the hip joint and finally end up in front of the knee and the ankle joint.

Basically, that is how you should look. Do you?

Being faithful to your exercise and health programs is an admirable trait. But what happens when it starts interfering with your life and more importantly to the lives of those who love you? I’ll tell you. It’s time to reappraise the situation and make some necessary changes.

Most hardcore fitness enthusiasts exercise come hell or high water, no matter what they will find a way to get their exercise session in every day. I know a person who has not missed one single day in over twenty years.

Every day this person did something positive for their health and fitness; even while recovering from major joint surgery. They have pushed to get better by regaining their range of motion and doing isometrics to build the muscle strength back to its pre-surgery status.

Has this dedication caused conflicts in their life? I suspect so. Let’s look at how you can avoid these same issues.

Putting the check on the calendar

I call minimally doing something positive for yourself putting a check on the calendar for that day. The check on the calendar simply means you did something on this particular day to help improve your health in some small way. It doesn’t mean you went all out on the exercises; just that you did a little bit.

Suppose you were scheduled to max out on one of your lifts or run a faster than normal mile but your wife or child became ill and had to be cared for. No one in their right mind would consider taking time off to exercise as planned if a loved one needed their help. You are no different.

Abandon your schedule and help them out. There will be breaks in the day when you can get out the skip rope and hit it hard. Do as many pushups and sit ups as you can in one or more minutes. Do something for yourself, but not at their expense, during the time you’ve got before they need you again.

If you aren’t in good mental and physical shape it’s going to be much harder caring for someone else.

Sometimes it really is better to stop the head long pursuit of strength and high level physical fitness and smell the roses for a brief minute or two before hitting it again. Just don’t take to long…

Prescriptions for strength training

300117 Starting a weight training program

Starting a weight training program.

Are you just beginning to lift weights? If so, then seeking out a knowledgeable coach to guide you along may be the first and most important thing you should consider doing. Check their credentials. Are they certified by a recognized organization such as the National Strength and Conditioning Association (NSCA) or the American College of Sports Medicine (ACSM)? Do they care about you or just your money and the gym membership? Ask them for references. After all, it truly is a buyer beware situation when you are trying to get stronger and are paying out good money for the results you desire.

Maximum lifts are to be avoided in any new weight training program. If this is the case then how are you expected to lift heavy if you don’t know how to lift in the first place? The answer is you can’t. So don’t be intimidated into adding more and more on the bar in your first sessions. Learn how to lift, build up a base and then gradually start adding the weight.

Excessive initial loads contribute little to becoming stronger but do expose you to an increased likelihood of injury. A new lifter will do quite well with a load varying in the range of 60-80% of a muscles force generating capability. You may be wondering how this is determined. One of the safer ways is to simply estimate a conservative load and try it out.

Another more frequently used method is to do a set amount of repetitions, i.e. ten, five or three, and then use commonly available charts to determine the percentage weight to use based on the outcome of the multi repetition test. Once the percentage has been figured out then the sets and reps will be a matter of professional knowledge and experience for your coach.

Using lighter weights for more repetitions is generally wiser for the inexperienced lifter. Selecting loads that allow ten to fifteen repetitions for two to four sets in each exercise helps build a strong base to continue future training. This repetition and set scheme will not place an excessive load on the bones, ligaments, muscles or tendons of the new lifter. More importantly it will not cause negative disruptions on the nervous system.

Certainly if the lifter is able to easily lift the selected percentage load for the chosen repetitions then more weight can be added the next session. A minimum of twelve repetitions is the determining factor in this decision to go to a higher load. This process will be trial and error for the first two to three sessions unless the coach is highly experienced.

Once the weight has been figured out then it’s time to set up the training load schedule in one of several ways: Progressive, over load, or step loading.

Progressive is effective for the new lifter for a short time then becomes less productive. The schedule will appear in this fashion. Three to four sets of various loads with a certain number of repetitions. For example, a warm up followed by one set of eight reps, then one set of six and finally one set of four. This schedule is followed for the rest of the training time.

The overload scheduling scheme leads to over training which in turn will lead to staleness, lack of interest and even injury. Many coaches like this as they believe the athlete benefits from the extra work. Not so. The athlete becomes disinterested and fatigued. In this system the load progressively increases every week or even every session. There is no rest built into this loading program and the constantly increasing intensity quickly leads to overtraining and its attendant problems.

The step load seems to be the best alternative for the new trainee in that one load is used throughout the entire sequence of one exercise. In the step load the warm up is completed and then one load is chosen which has been determined by the previous testing. This load then remains for three to five sets until it is no longer a challenge to the lifter. This is co-determined by both the lifter and the coach’s observations of the lifters speed and bar path.

An able coach will also start out the exercise session with a dynamic warm up such as riding a bike, skipping rope (my favorite warm up exercise) or some other active motion type of movement. If your coach starts out with static stretches then it’s time to find one more knowledgeable in the field.

Depending on the sessions some will begin with the larger muscle groups first and gradually work their way to the smaller ones such as the arms or calves. On other occasions the exercises will begin with the targeted muscle groups and work from this point onward.

One final note or two; keep a log of your progress in the weight room it will show you how well you’ve done…or not. If the or not is taking place it’s time to find another coach and begin to make some progress.
