In a unique study we compared muscle deficit in older and younger adults after 14-day bed rest. We have found higher deficit in older adults with also slower recovery. For the purpose of the study we used a newly developed sensor
We have developed a workstation for office workers. We monitored physiological responses, work efficiency and muscle contractile properties with newly developed sensor. We found that sitting position was proper and assures moderate physical activity with zero effect on work efficiency.
With newly developed sensor we measured adaptation of 5 skeletal muscles after 8-weeks of plyometric exercise. We have found higher contraction velocity and higher muscle tone. However, the magnitude of adaptation was muscle specific and that is impoprtant in dimensioning of exercise, particularly at compensatory exercises.
Muscle fatigue was monitoreed by newly developed sensor. We found fatigue of slow-twitch fibres and potentiation of fast-twitch fibres. This was the first study to examine not only single skeletal muscle but also determined fatigue in individual muscle fibre phenotype using decomposition technique.
We have demonstrated a presence and function of costameres that serves as focal adhesive molecules between muscle fibres. The concentration is highly dependent on sport performance. We have also developed a noninvasive procedure to detect costameres that until now could not be detected in anatomical levels but only after invasive biopsy procedure.
