Dynamography

Dynamography is a method of measuring the strength or power that develops as a result of muscle activity. This method is used to determine a person's physical ability to perform certain exercises. Dynamography can be used to assess the physical fitness of athletes, as well as to diagnose diseases of the musculoskeletal system.

Dynamography is carried out using special equipment that measures the strength and speed of muscle contraction. Depending on the type of exercise, different types of dynamographs may be used, such as dynamometers, electromyographs or special exercise machines.

To perform dynamography, you need to perform a specific exercise, for example, lifting a barbell or squatting. The force with which the person performs the exercise is then measured. The results of dynamography can be used to determine a person’s level of physical fitness, as well as to identify possible problems with the musculoskeletal system.

For example, if a person is unable to lift a certain weight, this may indicate muscle or joint problems. Dynamography can also help determine which muscle groups are most developed in a person, which can be useful when planning training.

In general, dynamography is an important tool for assessing a person’s physical fitness and diagnosing possible problems with his musculoskeletal system. It can be used both in sports medicine and in everyday life to improve health and increase physical activity.

*Dynamography* - measurement of the force developed by a muscle during its contraction. For the first time, dynamic muscle work was measured by the famous physiologist N. A. Mikhailov using the ergograph he invented. The introduction of dynamic loads into training for athletes and dancers who have little overall muscular development makes it possible to increase the level of special strength preparedness, ultimately at a more effective pace.

*Modern dynamometry* is the measurement of muscle strength using a special device called a dynamometer. Dynamometry is the general name for a set of methods for measuring muscle strength as a result of muscle contraction. During the application of these methods, the maximum resistance that a person can develop in a particular movement is determined. This resistance counteracts the traction force of the load itself. The maximum traction force of a person that does not cause him harm is called “useful”, “working”, “optimal”. Useful muscle strength is determined by the level of development of the musculoskeletal system of the person being studied, provided that his health is safe for working with this load. There are age, sex, typical, relative and absolute dynamometry. The maximum muscle resistance is determined quite accurately under the conditions of performing a special isolated, conditionally static movement. For this purpose, devices called dynamographs are used. Such movements are not accompanied by muscle fatigue. Then, the amount of muscle tissue that is replaced and included in the work depends on the duration of such a movement. Therefore, for older people, maximum tension or strength develops with a shorter duration of resistance compared to young people. With age, a person develops muscle wasting, which leads to a decrease (that is, dystrophy)
