The aim of this study was to identify relationships among the decline of muscle strength, aging and physical activity / inactivity in Czech adults. A cross-sectional study was conducted in 1,216 adults (167 physically inactive vs 1,049 physically active). The amount of skeletal muscle was determined by the bioimpedance device InBody 720 and muscle strength (hand grip strength) was measured by the hand dynamometer MIE in a dominant upper limb. # Based on the analysis of the data, we found a significant relationship (p < 0.05) between the amount of skeletal muscle and the level of muscle strength (hand grip strength) in the whole studied group (r = 0.86) and also separately in physically active (r = 0.87) and inactive (r = 0.81) individuals. The dependent variable (hand grip strength) can be explained by independent variables (age and the amount of muscle) via a multiple regression analysis. The regression equation for the physically inactive people is: hand grip strength = 0.16*age + 1.38*skeletal muscle (r2 = 0.699). For physically active people, the equation is: hand grip strength = -2.99 - 0.08*age + 1.5*skeletal muscle (r2 = 0.762). The results show a general decline in skeletal muscle and muscle strength with an increasing age, but the equations also indicate that age affects the decrease in strength and skeletal muscle in physically inactive people more than in active people. These findings correspond with the results of other studies.
