Today we will tell you in detail what measures the load cell, and what kinds of instrument exist.But before you answer these and other questions, it is necessary to understand what is meant by the term "dynamometry."As you know, the word is formed from two Greek: metron, that is, measure and dynamis - force.
It should be noted that this unit is particularly used in anthropometry, anthropology, in neuropathology, during professional selection, the study of military contingents, fatigue and so on.
What measures dynamometer?
From the above, we can safely conclude that the load cell - a special device by which absolutely anyone can easily and quickly measure their own muscle power.
way, evidence of such a device vary considerably depending on the length and difficulty of professional work.In that case, this method allows obtaining any of the results in graphical form, it is called dynamography.
Types of dynamometers
Currently, the device has shown a lot of different models.The most common among them is the dynamometer medical manual, which is intended to measure the muscle strength of the hand.Such a device is often called medical because it is often used in hospitals and clinics, equipment for medical offices in spas, sports facilities and schools.
However, the answer to the question of what measures the load cell can serve as not only the muscle strength of the hand.After all, there are variations of this product that is often used for measuring the strength of a similar leg muscle and body, characterizing the degree of physical development of a person.
dynamometer Medical: appearance and calculations
Using this manual medical device can easily and quickly determine the strength of muscles of the hand of the patient.During this procedure, the two measurements are carried out alternately on each hand, and then secured the best the best result.The external representation of the device resembles carpal expander.However, it looks a little different from the sensor and the measuring board.In addition, the load cell is designed not for cycling training, and for the only compression as possible for a human force.If this procedure is carried out for medical purposes, the hospital staff is required to place the results in a special register control.
for more objective indicators should subtract the relative value of muscle strength.After all, its growth during workouts quite closely correlated with the growth of muscle mass and body weight of the athlete.For example, you are able to independently determine the relative amount of force the hands of their own hands, they needed evidence that had been obtained in kilograms of hand Medical dynamometer, multiplied by a hundred, and then divided by the weight of the human body.So, for previously untrained men, this index is 60-70, and for women - 45-50%.
definition becomes force
calculating the power of the hands, you can check the results in such basic exercises like deadlifts.It is in this movement will be visible to all power quality person.This is due to the fact that in this exercise the athlete use all the major muscles of the body.
To accomplish this measurement, it is necessary to use a special device that looks very similar to a conventional foot expanders.It consists of a handle for hand and foot to the legs.However, instead of springs, this device has a cable with a kind of measuring instrument in the middle.
test task is to pull on the handle with the greatest possible force.In order to determine the necessary values should be similar manner as in the case of manual medical device to calculate the relative quantity becomes traction.The results can be interpreted as follows:
- less than 170% - low;
- from 170% to 200% - lower than the average;
- from 200% to 230% - the average;
- from 230% to 250% - higher than the average;
- more than 260% - the highest.
If in the process of training an athlete significantly increased relative strength indicators, this indicates a significant increase in muscle strength and, accordingly, the percentage increase in the content of the muscle mass.
Factors that somehow affect the power rates
In assessing muscle strength for self-control, we should not forget that it depends on individual factors such as:
- Age man.
- sex.
- athlete's body weight.
- Types of training influences.
- degree of fatigue and others.
In addition, muscle strength may vary considerably during all day.For example, the lowest value observed in the morning and evening, and the highest - in the middle of the day, that is in the middle.
is also worth noting that a significant decrease in muscle strength of an athlete or an ordinary person is often seen at the time:
- general malaise;
- any disease;
- violations of the day and food;
- emotional disturbances or negative mood, and so on.
In addition, the values on the dynamometer can be reduced in the elderly, as well as those who are over 40-50 years.A similar situation often seen in men or women, very rarely engaged in physical culture, including the usual gymnastics, walking and so on.
What you need to know the power rates?
Not everyone knows how and what measures the dynamometer.However, such a medical device rather well to those who exercise regularly.After systematic self-observation allows a creative person to take their daily training and a healthy lifestyle in general.Knowing their own indicators of muscle strength, the athlete is able to effectively and efficiently use physical training to strengthen the immune system and preserve health, and to improve the health and even the professional growth.
