The tensiomyographic method detected atrophic changes in muscle contractile properties before they could be detected by clinical imaging techniques. This is of great importance for the elderly population, who atrophy more than young people, and for the elderly the changes are irreversible. Muscular atrophy was triggered by bed rest for several days, thus ensuring a high internal quality of research and high quality of interpretation of the results. Changes were detected as early as 1-4days after bed rest initiation, while with imaging techniques only after 7-16days, depending on skeletal muscle.

In five skeletal muscle we estimated hybrid (biomchanical and mathematical) model of TMG parameter decomposition in relation to the measuring point. We found that the outcome strongly relate to the measuring point and thereofore, we proposed a standardisation of TMG repsonse assessment to control for minimal estimation error.

Although master athletes maintain high levels of physical activity, they also suffer from an age-related decline in skeletal muscle function. There are indications of disproportional age- and physical inactivity-induced muscle wasting between muscles. Tensiomyography is a non-invasive tool that has been used to study the effects of a variety of sports on the contraction time (Tc) in different skeletal muscles. The study reported was done in older nonathletes (age = 62.1±12.7 years; NMALES = 133; NFEMALES = 246), power-athletes (age = 56.9±13.5 years; NMALES = 100; NFEMALES =78) and endurance-athletes (age = 56.5±14.5 years; NMALES = 76; NFEMALES = 73). We found an age-related slowing in all muscles, where endurance master athletes had the longest and power master athletes had the shortest Tc. The longer Tc in endurance master athletes than in non-athletes suggests that regular endurance sport activity aggravates slowing and quality of contraction of skeletal muscles during ageing. This may to some extent, as in ageing, be related to glycation of myosin in these fibres.
