“…These include the use of the same model of dynamometer and identical grip strength measurement protocols. This is important given there are significant measurement differences in grip strength when different types of dynamometer and measurement protocols are employed 29,30 . In addition, we have been able to comprehensively investigate explanations of between‐study differences in grip strength due to the availability of data on a range of covariates assessed using comparable methods.…”

Background Identifying individuals with low grip strength is an initial step in many operational definitions of sarcopenia. As evidence indicates that contemporaneous Russian populations may have lower mean levels of grip strength than other populations in northern Europe, we aimed to: compare grip strength in Russian and Norwegian populations by age and sex; investigate whether height, body mass index, education, smoking status, alcohol use and health status explain observed differences and; examine implications for case‐finding low muscle strength. Methods We used harmonized cross‐sectional data on grip strength and covariates for participants aged 40–69 years from the Russian Know Your Heart study (KYH) (n = 3833) and the seventh survey of the Norwegian Tromsø Study (n = 5598). Maximum grip strength (kg) was assessed using the same protocol and device in both studies. Grip strength by age, sex and study was modelled using linear regression and between‐study differences were predicted from these models. Sex‐specific age‐standardized differences in grip strength and in prevalence of low muscle strength were estimated using the European population standard of 2013. Results Normal ranges of maximum grip strength in both studies combined were 33.8 to 67.0 kg in men and 18.7 to 40.1 kg in women. Mean grip strength was higher among Tromsø than KYH study participants and this difference did not vary markedly by age or sex. Adjustment for covariates, most notably height, attenuated between‐study differences but these differences were still evident at younger ages. For example, estimated between‐study differences in mean grip strength in fully adjusted models were 2.2 kg [95% confidence interval (CI) 1.4, 3.1] at 40 years and 1.0 kg (95% CI 0.5, 1.5) at 65 years in men (age × study interaction P = 0.09) and 1.1 kg (95% CI 0.4, 1.9) at age 40 years and −0.2 kg (95% CI −0.7, 0.3) at 65 years in women (age × study interaction P < 0.01). Conclusions We found between‐study differences in mean grip strength that are likely to translate into greater future risk of sarcopenia and poorer prospects of healthy ageing for Russian than Norwegian study participants. For example, the average Russian participant had a similar level of grip strength to a Norwegian participant 7 years older. Our findings suggest these differences may have their origins in childhood highlighting the need to consider interventions in early life to prevent sarcopenia.

The aim of this study was to estimate the relationship of the anthropometric parameters of an individual with the strength of the hand and the nature of the load distribution in its various zones when performing a cylindrical grip in practically healthy individuals. Anthropometric parameters and the results of biomechanical examination of both hands were analyzed in 78 practically healthy individuals (39 men, 39 women) of the most able-bodied age (from 19 to 50 years). The height and weight of the volunteers were measured using a manual electronic dynamometer ""Jamar Smart"" – the strength of the right and left hands (in kilograms). The dynamometry of the hand was performed in a sitting position, while the arms of the subject were located on the armrests, the elbow was bent at an angle of 90°, the forearm was in a neutral position, and the hand was in the extension position in the wrist joint at an angle of about 30°. The anthropometric characteristics of the hand were recorded by measuring (in cm) the lengths of the rays of the hand and fingers, and the length and width of the palm. Determination of the degree of load on various parts of the brush (as a percentage) was carried out using the hardware and software complex ""Teksan"" (USA). It is established that the strength of the brush depends on the anthropometric characteristics of the individual and its linear dimensions: the ""longer"" and ""wider"" the brush, the higher its strength indicators. When performing a cylindrical grip, the maximum load falls on the fingers, among which the I-IV are the most involved, to a lesser extent – the V finger and the tenar area. It was revealed that the load distribution indicators for different zones of the right and left hand differ: when performing a cylindrical grip with a weaker brush, the main load falls on the tenar area and the first finger. At the same time, the achievement of maximum grip with a weaker brush is achieved by the maximum involvement of small hand muscles in the process.
