We got a Sport foundation project to evaluate the effect of 8-week plyometric exercise on a sample of older subjects. The investigated experimental group exercised plyometrically for 60 minutes daily, and, the active control group exercised for ressitance exercise at lower speed. Only plyometric group advanced skeletal muscle contractile properties that explained in 40% the variance in explosive power enhancement. This has proven the validity of decomposition - sensibility to specific exercise training.

COBISS.SI-ID: 2536915In the invited lecture I presented the mechanical contractile properties of the muscles and its fibres. I've presented those temporal contractile properties that differentiate different muscle fibre types. I've presented our preliminary data which are today used to decompose TMG responses.

COBISS.SI-ID: 1540279492The triceps surae muscle group has a very important role in supporting human posture and gait and is thus particularly interesting in the context of healthy aging and independent locomotion of older people. Despite plenty of research on age-related changes in human limb muscles, the underlying mechanisms are still not completely understood and there is no common consensus on the effects of aging in triceps surae muscles and their causes. In this study, we used the decomposition of high-density surface EMG to analyze motor unit firing rates in triceps surae muscles of young and older subjects during isometric plantar flexion before and after 14-day bed rest. When compared to the young subjects, the motor unit firing rates of older subjects were significantly higher in gastrocnemii muscles and significantly lower in soleus muscle. The presented results demonstrate that the age-related changes in triceps surae are muscle specific.
