150817 Determining Food Toxicity 

 

By Danny M. O’Dell

In many cases checking the heart rate is a good indicator of the nervous system. For instance a quick test of overtraining is the pulse rate in the morning. If it is 10% above normal then this may illustrate the athlete is entering the pre-stages of over training. In another case, prior to attempting personal bests a high pulse rate implies there may be a psychological fear of the weight. The same heart rate comparisons that provided these snapshots into the athlete’s physical and mental condition can also give some indications that certain foods are not well tolerated by our body.

One method of checking food toxicity is by taking your pulse one half hour before eating a new food. This will be your baseline from which other readings will refer back to. Eat the meal and then begin taking your pulse over the next ninety minutes at thirty minute intervals. Make note of each of these readings.

Heart rate increases of more than 15 beats per minute suggest the food you just ate may not be agreeing with your body and you may want to consider finding a substitute.

One other method that may indicate a poor food choice is sweating. In my particular case within fifteen minutes of eating a toxic food my forehead has beads of sweat on it. Mostly this occurs after eating a fatty greasy (but delicious) hamburger.

250717 Sticking to an exercise program

250717 Sticking to an exercise program

There are those who exercise because they like it and those who exercise because someone told them they had to. Which one are you? If the latter, then perhaps you could benefit from a few tips on staying with it on your own.

Before doing any outside of normal activity see your doctor if any of these conditions exist in your background:

  • If you are a man over 40 or a woman over 50
    • If you have heart disease, high blood pressure, diabetes, osteoporosis, asthma or are obese.
    • Are at a high risk for heart disease, particularly so if you have a family history of the disease or stroke of if you have any other health risks that should be considered and subsequently evaluated by a medical professional.

Getting moving

  1. Activity counts, no matter what it may consist of it is still movement and movement is what activity is all about. Choose something you like to do and stick with it. It can be as simple as walking around your property or neighborhood.
    2. Get a mechanical motivator like a pedometer to track how many steps you took at the end of the day. Go for at least 10,000 steps each day and you will soon notice the health benefits of doing so.
    3. Start a logbook. Once written down you begin a history of your activity and soon will be reluctant to miss a session.
    4. Hook up with a friend and exercise together. Both of you will make gains in your health.
    5. If you don’t have time to get a full session in then split it up into more manageable times. The current wisdom is ten minutes is about the shortest time that makes positive changes in your body and ultimately your health.
    6. Use the stairs at work or in the stores. Get that body moving. Don’t get lazy by taking the easy way out on the mechanical devices to get somewhere.
    7. Eat your noon meal on the go, get out in the fresh air by walking or doing something that gets your heart rate up.

Your body was built to move and not just sit on its butt.

270617 The Myth of Spot Reduction Exercises

 

270617 The Myth of Spot Reduction Exercises

Spot reducing exercises do not work and if your trainer is pushing you to do hundreds of sit ups in the effort to tighten up your abdominal muscles and in turn reduce the circumference then find another one. In a study performed by people doing over 5000 sit ups in a twenty seven day period it was found that size changes in the adipose cells of the abdomen were similar to the size changes in the glutes and the subscapular regions.

The training did accomplish one thing; it reduced the size of the adipose cells in all three locations not just the stomach.

If weight reduction is your goal then add in strength training and cut back on the endless cardio sessions. Muscle burns more calories per hour which at the end of the day means more expenditure of energy and better utilization of the caloric intake. This adds up to consistent weight loss if followed correctly.

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:

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

    *Essentials of Strength Training and Conditioning
    Baechle, T. R., Earle, R.W. Human Kinetics 2001

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.

160517 The major keys to good bone health

*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

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.

100417 Acute Hormonal Responses to Varying Protocols in Men and Women

A recent study by William J. Kraemer and associates showed the hormonal response benefits of three separate types of maximum heavy resistance training protocols. This group examined the response effects from the bench press, sit up and bilateral leg extensions exercises based upon percentages of the maximal ten repetition, five set scheme with a two minute rest between each set.

The three exercise program variances were:

Heavy maximal 10 repetition maximal (10 RM) loads of five sets of ten repetitions with a two minute rest in between the sets.

Submaximal heavy resistance 70% of the 10 RM.

Maximal Explosive resistance of 40% 10 RM

The results were pretty clear after the study was finished as to which protocol released the greatest amount of growth hormones. There was a significant increase in the serum growth hormone after the heavy maximal ten rep/five sets were completed. And, this was true in both men and women, but more so for the men than the women. Serum testosterone significantly increased in the men, but not the women and only while engaging in the heavy maximal sessions.

Since these two substances are critical to long-term adaptations of strength and power this study may help in the long-term process of inducing greater muscle hypertrophy and maximal strength development.

Adapting the heavy loading hypertrophic type of exercise sessions appears to foster growth in the muscle mass for men if they use the heavy maximal load for ten reps and five sets with the suggested two-minute rest in between sets. These hormonal responses seem to be related to the amount of muscle mass activated in the exercises. Using the submaximal and the explosive maximal loads did not elicit increases in the release of these hormones, as it was not strenuous enough to the organism.

Neural control and the achievement of higher rates of force development are fostered, at least in the men, with the explosive maximal loads. Whereas in the women the responses after exercising with explosive maximal weights did not seem to be that clear cut. For women it would seem best to train with the explosive maximal and the heavier maximal loads.

030417 Spare tire risks associated with carrying fat around your stomach.(1/2)

030417 Spare tire risks associated with carrying fat around your stomach.(1/2)

By Danny M. O’Dell, MA. CSCS*D

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.

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.
