200617 Bone Health Exercise Recommendations

200617 Bone Health Exercise Recommendations

The mode of exercise should be a combination of weight bearing and endurance activities such as stair climbing, tennis, jogging and jumping. Add in regular sessions of resistance training to round out the weeks program.

The intensity level of all these exertions has to be in the moderate to high ranges in order to engage the bone loading force mechanisms leading to high quality rebuilding of these tissues.

The resistance training level of intensity will be in the 80-85% areas for the majority of the selected movements. The selected exercises are those that involve the major muscle groups that focus on the shoulders, chest, upper back and the legs front and rear. Repetitions will be in the 6-8 range for two to four sets with two to three minutes rest between sets.

These exercise sessions need to be at least as frequent as 3-5 times per week for the weight bearing endurance activities and 2-3 times per week for the resistance ones in order to elicit a positive effect on the skeletal structure.

Once these regimes are in place the desired time spent on each one per session is 30-80 minutes per day. This will be a combination of both types of exercise and not just one of the two recommended modes.

130617 Exercise suggestions for increasing bone mineral density

Before engaging in any new exercise program consult with your primary health care provider.

To increase your lean body mass, add strength and power, follow these guidelines for the suggested group of exercises:

1. Full body resistance training program on a schedule of at least two times per week, with three times to optimize the results.
2. Utilize correct exercise technique at all times
3. Three sets of ten to twelve repetitions each exercise unless otherwise noted.
4. Work to rest ratio is 1:2, meaning if you work out for ten seconds you then rest for twenty seconds.
5. If you are able to add weight after completing the series three times, then do so the next session.
6. If you have added weight then do only ten repetitions and work up to twelve.

Warm up for 5-8 minutes
Squats
Calf raises
Dead lifts
Military presses
Shoulder shrugs
Abdominal work-15-20 reps for two sets
Bench presses
Bar bell rows
Barbell curls
Triceps extensions
Abdominal work again to end the session-15-20 reps for two sets

060617 Mechanical load consists of the following:

Magnitude of force

Magnitude of the load density or the intensity of the load will generally be above eighty to ninety percent one to ten repetition maximum in order to see improvements in the tissue response.

Speed of force development

The rate or speed of loading means how fast the force is being applied to move the load in a concentric muscle contraction (force applied against a weight with the muscles shortening). Think speed during the lift.

The direction of forces

Varying the direction and pattern of movement will stress the bone and the attaching musculature. Full range of motion in all exercises ensures to a certain extent that the forces are applied as required.

Volume of force applied

The first three mentioned above are primarily responsible for bone mineral improvements. Typically the repetitions do not need to exceed thirty to thirty five to see improvements IF the load is within the correct intensity zone (80%-90% 1-10RM).

Exercise prescriptions for bone growth stimulation*

  1. Volume 10 reps for 3-6 sets
    2. Load 1-10 RM at 80%-90%
    3. Rest 1-4 minutes between sets
    4. Variation Undulating periodization patterns
    5. Exercise selection Structural, multi-joint, large muscle groups

Summary:

The greater the magnitude or intensity, the higher and faster the power output, and the direction of force all contribute to the successful laying down of new bone growth.

300517 The stimulus for new bone formations.

300517 The stimulus for new bone formations.

Minimal essential strain (MES) refers to the threshold amount of stress applied to the structure which is necessary to elicit growth of new bone material. A force exceeding MES is required to signal the osteoblasts to move toward the periosteum and begin this transformation. MES is thought to be 1/10 of the breaking force needed to fracture the bone. Training effects have a positive relationship to bone density just as sedentary living habits play a role in the loss of bone density.

Training to increase bone formation

Programs designed to stimulate bone growth, also known as bone mineral density (BMS), will incorporate the following characteristics:

  1. Specificity of loading
    2. Proper exercise selection
    3. Progressive overload
    4. Variation

Specificity of loading will see the exercise patterns emphasizing specific areas in need of assistance. New or unusual forces in varying angles of stress will enable your bones to adapt to the greater intensities. Military presses, bench presses, upright shoulder shrugs, push ups, chin ups, plus other similar exercises would help develop stronger upper body bones. Lower body exercises selections would be along the lines of these types of movement patterns: squats, calf raises, dead lifts, and straight leg dead lifts.

Exercise selection promotes osteogenic stimuli (factors that stimulate new bone formation) and will exhibit these characteristics: Compound exercise muscle movements consisting of multi joint, structural loading and varying force vectors. Such exercises are the squat, dead lift, military press and the bench press along with the Olympic style moves.

Progressive overload

Greater than normal loads force the body to adapt in a positive manner regarding new bone formation. This response is greater if the load changes are dramatic and repetitive in nature. Younger bones may be more receptive to osteogenic changes in the load variance than older bones.

Variations of exercise selections

The body adapts quickly to imposed loads per the SAID (Specific Adaptation to Imposed Loads) principle. In order to prevent accommodation the exercises need to be varied on a periodic basis. There are many individual differences in the same exercise. As an example the squat has at least seventy variations! And these variations do not include any machine versions.

230517 Adaptation of Bone to Exercise

230517 Adaptation of Bone to Exercise

By Danny M. O’Dell, MA.CSCS*D

Background information-briefly stated

Bone is considered a connective tissue that when stressed, deforms and adapts as a result of the load. To meet the strain imposed upon the external structure caused by the bending, compressive, torsional loads and the muscular contractions at the tendinous insertion point’s osteoblasts migrate to the surface of the bone.

At the point of the strain, immediate modeling of the bone begins. Proteins form a matrix between the bone cells. This causes the bone to become denser due to the calcification process occurring during the growth response to the load.

The new growth occurs on the outside of the bone to allow the manufacture of new cells to continue in the limited space with in the bone itself. This outer layer is commonly known as the periosteum.

Adaptations take place at different rates in the axial skeleton (skull/cranium, vertebral, ribs, and sternum) and the appendicular skeleton (shoulder, hips, pelvis and the long bones of the upper and lower body-essentially the arms and legs). This is due to the differences in the bone types- trabecular (spongy) and cortical (compact) bone.

*Exercise plays a highly beneficial role in maintaining bone integrity and preventing fractures by increasing the strength of the bones.

*Bone mineral density is directly related to long term physical activity via load bearing, impact exercise regimens.

*The loss of bone mineral density weakens the bones and makes them susceptible to a fracture.

*The sites most frequently fractured are in the hip, spine, and wrist.

Summary:

Take care of your health by exercising, eating right and having yearly full physical exams.

090517 Osteoporosis strength training

High impact exercise such as these listed builds stronger bones

  • Vertical jumps
  • Skipping rope
  • Jogging in place
  • Knees semi straight hops in place
  • Ankle hops
  • March around your home or gym with dumbbells or extra weight on your shoulders

Weight bearing aerobics

  • Walk with a set of dumbbells. Avoid repetitive motion injuries by switching up on your method of carrying the extra weight on your walk or run.

There is a delayed response of up to six months before changes in your bone mineral density will be noticeable. Weight bearing and bone load bearing lowers your risk of fractures.

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.

091013 Early detection of disease – screenings for men

Early detection of disease – screenings for men

The earlier a disease is detected, the better off you may be. If you begin treatment soon after finding the problem the treatment is more effective in the early stages and the greater, the likelihood is that you will avoid any complications from the disease.

There are many opinions from various medical organizations recommending different health screenings at different frequencies in your life to consider. Your personal health history, as well as that of your close relatives, will have an influence on your decision to have these tests.

Don’t waste your money on useless tests; consult with your doctor to find out the ones that may benefit you the most. The following recommendations are generally those providing the greatest information for continued monitoring of your health.

Blood pressure readings measure the force of the blood against the walls of the arteries. The Joint National Committee on Prevention, Detection, Evaluation, and Treatment of high blood pressure advises getting this done at least every two years for anyone past the age of eighteen.

The National Osteoporosis Foundation counsels getting a bone mineral density test (BMT) at least one time for men over seventy years of age. A BMT is an Osteoporosis test that screens for brittle, weak bones leading causes of fractures in the elderly and those with osteoporosis.

Colon cancer screening tests for colon cancer or precancerous polyps. The American Cancer Society recommends the following schedule for these tests:

• At age fifty men should have tests for polyps and cancer with a flexible sigmoidoscopy every five years
• Colonoscopy every ten years
• Double contrast barium enema every five years or CT a colonography which is a virtual colonoscopy, every five years.
• Tests with the principle goal of finding cancer include:
o a yearly fecal occult blood test or a
o yearly fecal immunochemical test
• Diabetes screening tests. These check if you have high blood sugar. According to the American Diabetes Association these should be done every three years once you are past forty five years of age.
• The American Optometric Association advises regular eye exams along these lines:
o Ages 18-60 every two years
o Beyond age 61 every year
• Determining the fasting lipoprotein profile every five years, beginning at age twenty plus is the goal of the National Cholesterol Education Program Expert Panel. This checks the cholesterol levels in your body, which is one measure of your hearts health.
• The American Cancer Society recommends prostate screening for possible signs of prostate cancer starting at age 50. However, before jumping into the tests discuss the benefits and potential false readings with your doctor. For certain, African American’s and men with a family history of prostate cancer should be getting tested on a regular basis at an earlier date in their lives.

None of these tests are painful and there is no excuse not to be getting them on a regular basis.

240513 Strength and flexibility training-2

Increasing your lean muscle mass through the use of bodyweight, bands or free weight exercises  boosts your metabolism, maintains and increases your bone mineral density. A study conducted in 2002-2003 showed that regular strength training, note the words strength training, reduced the risk of coronary heart disease by approximately twenty three percent when compared to men who did not resistance train.

As a minimum, head off to the gym or to your exercise room and work the large muscle groups at least three times a week on alternate days for a minimum of twenty minutes each session. If you’re already exercising for twenty minutes then bump it up to thirty with the goal of forty five to fifty minutes three times a week. Do so in stages of ten percent per week until you reach the top times.

The large muscle groups include the shoulders, chest, legs and back. You can use your body weight, free weights or elastic materials during these training sessions. Keep a log book.

After the strength training session is over, move into five to ten minutes of static stretching. Hold these stretches at the point of mild discomfort for ten to thirty seconds, three to five times per stretch per area.

Stretching will improve your flexibility; the answer to those tight lower back, hamstring and shoulder muscles and joints. It is vital that you do stretches for your calves, thighs, hips, low back, your neck and shoulders if you want to stay fluid in your movements. Do them slowly and hold them for the prescribed amounts of time for each one.
