Two HIT Abolutes Always Ignored

Muscular contraction, produce rotational movement around one or more joints.

A force moving in one direction, produces and equal amount of force in the opposite direction: force and or counter force. Without adequate stability, when one applies force in one direction, other parts of the body move in various other directions.

In the sense of Fitness Therapy, testing and evaluation, this unwanted movement affects the patient's ability to produce maximal contraction. Joint instability can also lead to further injury.
ome argue, that areas of the body should not be isolated or stabilized, because: "during daily activities, muscles are not working in isolation."

This may be true; however, for specific testing, and maximum functional improvement, body segments must be isolated to prevent contributing to the movement. If for example, a movement involves three different muscle groups, and muscle group #3 is the problem area.

Wouldn't it make sense to isolate and specialize on the problem area, rather than wasting time, money and energy, rehabilitating areas that are already fully functional. Naturally, in any movement, the weaker muscle will be the weakest link in the chain.

Time efficient and cost effective Fitness Therapy, does not require the exercise of body segments already functional. We recommend focusing with laser precision on the functional deficient areas.

Rational therapy demands the consideration of force--counter force, as well as isolation and sharply focused attention to the weaker, problem area. Certain High-tech machines, which do not take this into account are, to our mind, classified as inferior machines.

Consideration of Body Segment Weight

When one step on a scale, a number is produced, we call it body weight.
Body weight consists of, total body segment weight, of all segments. The body segment weight, meaning: body weight is made up of various body segments, such as: the weight of the upper arm (shoulder to elbow), lower arm (elbow to wrist) and hand.

Each segment has a weight to it.

Segment weight makes movement easier; or, depending on which way one is moving, the segment weight will make the movement "harder." As an example: when one curls the palm up towards the shoulder, you are also curling the weight of the lower arm and hand.

If one is lifting a weight in similar fashion, one is lifting the weight plus the weight of the lower arm and hand. "So, what"?, you say.

Well, my friend, when it comes to testing muscular strength or attempting rehabilitative exercise, just the body segment weight, may make it impossible for a patient to produce movement, via muscular contraction and prevent movement, throughout a complete range of motion.

This is often seen when a patient has a lower back problem. Many times, they can lean forward towards the floor. This is an example of the body segments weight (torso, arms, neck, and head) working with the person, as gravity pulls them forward towards the floor.

Now, suppose they don't want to spend their life in a bent over position and would like to stand upright again. Segment weight that worked "with" them, will now work "against" them, as they must lift the weight with muscle contraction of the lumbar spine musculature.

Imagine you were testing a patient's lower back strength on a so-called back machine. Usually the person is asked to "lift" a certain amount of weight or produce a static contraction, by attempting to move in a backward direction.

This effort is measured, against a stress gage or monitored by computer. Lets say the movement arm is against the upper back area and a certain amount of weight is lifted, or muscular torque produced. If person "lifted" 100 pounds. It is always assumed that is a correct figure. After all, they did "lift" l00 pounds, so that must be the static strength of the muscles tested, right?

Wrong! Here's why!

The amount actually lifted was the l00 PLUS the weight of the body segments involved in the movement. So, their strength is greater than what is believed to be, according to the so called "accurate measurement"

Invalid Testing Data

So, a therapist starts the rehab program with invalid data. There are several ways this will invalidate progress. Here's a far out example:

Suppose a person weighing 150 total pounds has an upper torso weight of 50 pounds. If they are put on a weight loss diet, along with therapy, they will appear to become stronger, as they lose weight, but, they may not be stronger. It happens this way. As one loses body weight, it is lost from all areas of the body.

Some is lost from the upper body areas. Say 30 pounds of fat, was lost from the upper body. Whatever increase in back strength the person appeared to gain in lifting ability, must be decreased by 30 pounds.

It's as if 30 pounds was taken off the weight the person lifts. This is rather a long way around explaining how body segment weight must be considered, when discussing a person's true strength. The true strength of a muscle is always more than it appears, given traditional muscle testing. The net effect is false data and a slower rehabilitation period than is necessary.

If a therapist assumes the "lifting" data is correct, they go on to design a rehab program based on the patient's supposed strength. So, they use some percentage of the maximum strength level as a starting point for a rehab program, relating to the injured area.

If the person tested 100 pounds strong and the therapist takes a percentage -- say 60 percent -- they start with a 60 pound workload. This load will usually prove to be too light, in relationship to the true strength of the muscles.

However, because the therapist believes the data, they supervise several weeks of programs, going through the motions of what is supposed to be a productive, proactive therapy program.

Illusionary Progress

Several weeks (or months) later, the patient has progressed from 60 pounds to 100 pounds. Wow, it appears there is a 40 percent improvement. In fact, there may be no improvement at all, because the program was based on a max strength level of l00.

The true strength was l00 PLUS the the segment weight that went along for the ride.

Perhaps the person should have used 60 percent of l50 pounds (100 of the strength data plus the 50 pounds of body segments), the muscles also lifted. If we use 150 as the true static strength level and take 60 percent as the initial workout load, we would use 90 pounds.

This amount would be much closer to the actual strength of the muscles and would therefore tax them at the proper level, producing faster rehabilitation

Who is The World's Strongest Person?

Carrying the idea of segment weight farther, it can be stated that any weight lifting record, may or may not be a record, because the body segments involved in the lifting, will or will not weight more from one person to the other.

As an example, lifting a barbell overhead is one test of strength. Although the weight of the barbell may be X overlooked in the "lifting" total was the weight of the hands, forearms and upper arms of the lifter.

One person may have lifted "more" than the other, when we calculate the body segment weight.

The answer to the question: "Who is the world's strongest person?" is:

No one really knows. Especially if the record was broken by only a few pounds.

Because the body segment weight, has never been taken into consideration.
