Training theories 291018 5/5

Two models of thought predominate the current thinking in strength training. One is ‘supercompensation’ or the one-factor theory, the second is the ‘fitness-fatigue’, also known as the two-factor theory. These two are generalized theories and as such contain only the most essential portions of the training ideas. Extraneous options are not included in this brief snap shot of these two training programs.

A rough rule of thumb with a normal training load is the duration of the fitness gains and the impact of fatigue differ by a factor of three. That is the fatigue effect is three times shorter than the positive effects, which last up to three times longer. As an example if the effects of fatigue last 24 hours, the improvement in fitness lasts 72 hours.

Using the two factor model the coach must keep in mind the two offsetting components of training and plan each follow up session accordingly. Maintenance of preparedness, avoidance of fatigue and continual training sessions comprised of several warm up type sessions prior to a contest. The idea behind this is to decrease the training load during each session rather than reduce the number of training sessions. A tapering off of the training load has been proven to enhance the final strength outcome.

In order to accomplish this feat the intervals between sessions must be long enough so the “negative traces of the preceding workout pass out of existence but the positive fitness gains persists.” This has become a rather popular model for use in planning strength training programs.

Two factor theory (Fitness-fatigue theory)

This “theory of training is much more sophisticated than the supercompensation theory”. Its basis is the premise “that preparedness, characterized by the athlete’s potential sport potential performance is not stable but rather varies with time. There are two components of the athlete’s preparedness:

Those that are slow changing, for example, physical fitness is a slow changing phenomenon. It does not change a substantial amount over short periods of minutes, hours or even days.
Fast changing such as physical fatigue (a temporary lowered ability to work because of disturbed homeostasis resulting from performing this work ), illness, the athlete’s disposition toward competition, intellectual, and sensory inputs may all change quickly.

According to this theory, the immediate effect of the training is a combination of two processes:

  1. The gain in the fitness which was prompted by the workout
  2. Fatigue resulting from the workout

The sum of the two effects is an increase in fitness due to the workout that is offset by a deterioration of fitness due to fatigue. The outcome is a balancing act of positive and negative actions within the body. If the fitness increase is greater than the effects of fatigue, the organism grows stronger. If not the opposite is true.

Extraneous options are not included in this brief snap shot of these two training programs.

Several popular methods try to achieve this state. One is overloading in a Microcycle, one heavy cycle of training is followed, after a brief rest, by another heavy training cycle. A lengthy rest and restorative period is then included in the schedule. The belief is that by adhering to this schedule the final supercompensation will be greater than normally results from a training cycle.

A critical look at this theory leads one to believe it may be too simplistic to be of much use any longer. The very fact that supercompensation even exists is not a proven fact in scientific experiments. Glycogen depletion, however, is a fact after heavy exercise. It is a possible to increase glycogen in the cells via a particular program of correct training and carbohydrate loading-but only before important competitions. Replication in everyday training situations has not been proven.

ADP, adenosine triphosphate, generally thought to deplete after heavy exercise in fact shows little change at all in the cells. Other substances require differing amounts of time to restore to initial levels.

It is unclear as to which substance the program planning should be adjusting to in anticipation of a supercompensation result. “In general, the theory of supercompensation is too simple to be correct. Over the last few years it has lost much of it popularity”.

Supercompensation

In order for this to work, the program design must take into account the phases of enhanced absorption and plan accordingly for these periods. If, on the other hand, the program planner inserts a workout before the cells have had a chance to take on the higher levels of the growth producing substances they will be less apt to tolerate the new load. An injury or deleterious cell damage will be the result rather than growth occurring.

Equally disruptive to growth is a lengthy period between workouts. After too much time has elapsed, the cells will revert to their normal status. Perhaps a small amount of growth will take place but not nearly as much as if the period had been correctly planned.

The coach has to keep in mind these two variables while planning a program.

Optimal rest periods between successive training sessions and
An optimal load in each workout.

“The aim selecting these intervals and loads is to ensure that a subsequent trading session coincides with the supercompensation phase”.

Lifting weights implies wearing the correct attire to help prevent injuries from occurring. Some of the personal adornments that have shown up in the gym are just this side of ludicrous and certainly not appropriate in the weight room. Some examples are listed next.

*Large necklaces that make it difficult to rest a bar on the upper torso are something better left in the locker or at home.
*Rings on every finger that dig into the skin during a chin up, curl or dead lift.
*Flip flops or sandals of any sort have no place in the gym.

The last mentioned is in my opinion the most critical of those on the list. A shoe that fully encloses your foot provides a bit of security if a piece of equipment falls and hit the foot. A sandal gives you no protection at all.

Select shoes that give good ankle and solid arch support. They should also provide your foot with superior lateral stability by having good upper support; unlike the smaller low cut running shoes. The shoe also needs to have enough room in the toe box to prevent your toes from rubbing at the tips. If you plan to do lateral cutting drills in your program then make certain the shoes you chose have excellent traction capabilities.

040618 The general principles of the warm up 1/4

The warm up session starts with exercises that are low in intensity, progressing up to the actual work out movements. Starting with high intensity exercises leaves little left in reserve for the main work out. The body quickly uses its stored muscle glycogen and increases the lactate levels in the blood when engaged in high intensity work. When the lactate increases the free fatty acids decrease leaving less to help produce energy. You don’t get into your car on a cold morning and go racing out the drive way and onto the expressway at maximum speed. It’s the same for our bodies; warm them up for the tasks ahead.

General principles of arranging warm up exercises normally follow few these guidelines. Start from the distant joints and work toward the center or proximal portion of the body, from one end to the other or from top to bottom or vice versa. The exercises move from one into another so that the end of one move floats directly into the start of the next movement. This is also how a regular strength training session should be set up.

A solid warm-up will take anywhere from twenty to forty minutes. Many people don’t have the time to take this long so adaptations will have to be made by taking into account the total length of the exercise session. If the intensity of the workout is high then the warm up will, of necessity, be longer. Longer warm up periods would be in order for the explosive sports endeavors such as sprinting and the more difficult technical sessions. Aerobic and endurance exercise periods need much less, as the pre stages of these activities are in and of themselves a warm up.

Repeating the same warm up in successive workouts is not beneficial to the athlete as the goals of each workout are not necessarily the same, thus the warm up should reflect the workout goal. The warm up should prepare the athlete for the workout; bearing this in mind the last minutes of the warm up will be more or less specific to the first training exercises and ultimately blend into the actual workout itself. After the session has started then each different move will be preceded by its own specific but short warm up as the training continues onward.

190218 Blood pressure, daily walking and the connection with being overweight

If you are overweight, then daily walking may not dramatically decrease your blood pressure. The healthy benefits that walking has on the blood vessels of a normal weight person may be lost on the overweight individual.

In general, terms this means that your arteries are not widening and the blood flow is not improved with walking, thus your blood pressure may not change to more optimum numbers.

Researchers at the University of Texas Southwestern conducted a study that analyzed over 35,000 Caucasian men and women. Each person in the study had regular checkups that included measurements of their Body Mass Index (BMI), and readings of their systolic blood pressure each visit. Additionally these participants exercised at each visit so their fitness levels could be assessed. The results may give anyone who is overweight a reason to reassess their situation.

The results were published in the American heart journal and they revealed that a normal weight person had an average of 12 mmHg lower systolic blood pressure than one who was obese. The blood pressure of the fittest was only 6 mmHg lower than for those who were least fit. Still, that wasn’t all they found.

After analyzing the blood pressure, BMI, and fitness data of the participants, they found that physical fitness was an important element in lowering blood pressure in those of a normal weight person. However, it was not as effective of a component in those who were overweight. Interestingly enough, many in this overweight group were physically fit yet their blood pressure was still high.

The take-home message here certainly indicates that diet alone may not help lower your blood pressure. The combination of losing weight, by engaging in regular exercise, and calorie counting will need to be in place before you begin to notice the beneficial effects of exercise on lowering your blood pressure.

By Danny M. O’Dell, M.A. CSCS

High blood pressure is the direct cause of thousands of needless deaths a year. Here are just a few of the facts about hypertension.

Dr. Laura Svetkey, director of the Duke Hypertension Center at Duke University states. “Americans can keep blood pressure low if they: keep trim, exercise, cut back on saturated fats, limit alcohol and sodium, increase dietary potassium and eat plenty of fruit and vegetables”. http://www.bupa.co.uk/

There are positive, and negative, effects on our blood pressure when we exercise or exert ourselves physically and/or mentally.

Blood pressure is the measure of the force of the blood pushing against the walls of the arteries. Hypertension is the medical term for high blood pressure. One in FIVE Americans has Hypertension. Many do not even know they have it, thus the term “the silent killer” It is not uncommon for young people to have hypertension.

Blood pressure is measured by stopping the blood flow for a few seconds and then beginning again. The amount of pressure the monitor detects accurately reflects the resistance your heart is pushing against each time it beats. The monitor works in the following fashion:

The arm cuff is placed on the upper arm or forearm. The brachial artery is then pinched off to stop the flow of blood. The circulation is briefly cut off, and then the air is let out of the cuff. The first heartbeat heard is the Systolic and the last one heard is the Diastolic.

Systolic pressure is the upper number in the formula

  • When the heart contracts to pump out the blood. Pressure is highest during this phase of the process

Diastolic pressure is the lower number.

  • The heart relaxes after pumping. Pressure drops to its lowest point just before a new beat.

Pre-hypertensive

Previously pressure readings below 130/85 were considered normal.

Previously readings above 130-139 over 85-89 were considered to be in the high normal range.

220118 Burning off the calories and keeping healthy

Physical activity burns calories. The optimum method of controlling your weight is a combination of good nutrition (see a registered dietitian), and exercise. The question now is what kind of exercise is the most efficient and longest lasting in its effects.

Many people use aerobics to successfully to help control their weight and improve their physical fitness while others use strength training to achieve similar goals.

In each case, physical activity speeds up your metabolism for a few hours afterwards. Of course, how much this materializes depends a great deal on the intensity and duration of the activity. Nonetheless, it happens and at a higher rate than if you did nothing at all.

The best way to keep this higher rate of calorie burning is to strength train. The reason: strength training increases your lean muscle to fat ratio. The higher this ratio is the more your body burns the calories because muscle tissue is more metabolically active than fat tissue.

Strive to strength train 2-4 times a week for a minimum of thirty to fifty minutes at a time. Do your large muscle groups such as the chest, shoulders, legs, and back for 3-5 sets of 8 to twelve repetitions for each exercise. On the off days from strength training, do your aerobic training for fifteen to forty minutes per session.

No matter which method you choose, consult with your doctor beforehand, keep the intensity up, and stick with it.
