NECESSARY EQUIPMENT
Hand dynamometer with the ability to calibrate and reposition the handles
TESTING
The purpose of the dynamometer test is to measure the maximum isometric strength of the muscles of the hand and forearm.
Hand strength is important in any sport in which hands are used to perform technical movements.
The subject holds a dynamometer in his working hand, the angle between the shoulder and forearm is 90 degrees, the elbow joint is located on the side of the body.
If necessary, adjust the handles of the dynamometer - the base should rest on the middle of the palm, and the finger handle should be at the level of the middle of four fingers.
On command, the subject compresses the dynamometer with a maximum isometric force, which is maintained for about 5 seconds.
No other hand and body movements are allowed.
OPTIONS
The position of the hand and wrist may vary in different dynamometer test protocols.
The positions of the elbow joint are also variable - from a position fixed at right angles in accordance with the above procedure, with the arm laid aside, in the movement of an outstretched arm from above above the head during compression.
Eurofit dynamometry test recommends compressing the dynamometer for 3 seconds.
With dynamometry in the Groningen Elderly Tests, three attempts are made with an interval of 30 seconds between them.
RESULT
The best result is recorded for each hand from several attempts with a recovery interval of at least 15 seconds.
Input the received indicator in the form below and get an assessment and conclusion.
You can evaluate the right and left hands.
RELIABILITY
The reliability of this test for assessing total strength has previously been called into question, since the strength of the muscles of the forearm will not necessarily correlate with the strength of other muscle groups.
If you need to measure the strength of a particular muscle group, there are other tests that can be used for this.
The dynamometer requires regular calibration to provide standardized results.
To ensure the reliability of the measurement results, a proven technique is required and sufficient rest between trials.
ADVANTAGES
Dynamometry is a simple and frequently used test for assessing the general level of muscle strength, well studied, with repeatedly tested standards. Especially valuable is the test for assessing muscle strength in the elderly, it also allows you to indirectly assess the hardness of the skeletal system.
LIMITATIONS
The dynamometer should be adjusted to the size of the palm.
As far as this is successfully done, the measurement indicators will be more accurate.
COMMENTS
- It is useful to mark the dominant hand, which may help in interpreting the results.
- A non-dominant hand usually has indicators 10% lower.
- The muscles of the forearm quickly tire, so the best results are usually achieved in the first or second attempt.
- Keep in mind that the results will vary between men and women, between right-handed and left-handed (dominant and non-dominant) hands and with age. The position of the hand, elbow, and shoulder may also influence the results, so their position during the test must be consistent with the standards.
