Jamar Hand Dynamometer

Our organization have been actively engaged in distributing and supplying a premium quality Jamar Hand Dynamometer in Ahmedabad, Gujarat, India.

Because of its reliability in providing results, the Jamar hand dynamometer was used as part of a group of studies measuring hand strength across a lifespan. The group of 12 studies were published in the PLoS One Journal, a peer-reviewed open access journal attempted to show that weaker grip strength in later life is associated with disability, morbidity, and mortality. The published findings combined 60,803 observations from 49,964 participants (26,687 female) of 12 general population studies in Great Britain. Out of these 12 studies, 7 used the Jamar Hydraulic grip dynamometer to perform the grip strength testing.

With the use of the Jamar dynamometer, scientists were able to pinpoint 3 distinct periods for strength: an increase to peak in early adult life, maintenance through to midlife, and decline from midlife onwards. Not only that, but repeatable results showed that males were on average stronger than females beginning in adolescence onward. For example, malesa peak median grip was 51 kg between ages 29 and 39 and females peak median grip was 31 kg between ages 26 and 42. Additionally, study results showed that weak grip strength increased sharply with age, reaching a decrease in strength by at least 23% in males and 27% in females by age 80.
