Electromechanical efficiency (EME) of skeletal muscle represents the dissociation between the mechanomyographic (MMG) to electromyographic (EMG) amplitudes and was commonly used in clinical settings (e.g. muscle disease, atrophy, rehabilitation). However, due to lower reliability and of both MMG and EMG as well as lower validity of MMG we aimed to establish the intra-day, inter-day and inter-rater reliability of modified EME. Reliability was examined for maximal soleus twitch amplitudes of tensiomyographic (Dm) and M-wave (Mptp) responses, as well as for EME derived as Dm/Mptp, in 18 healthy participants in three consecutive days. Average ICCs ranged from 0.92 (Dm) to 0.97 (Mptp), 0.88 (Dm) to 0.92 EME and from 0.96 (both Dm and Mptp) to 0.98 (EME), for intra-day, inter-day and inter-rater, respectively. CV% ranged from 5.3 (Mptp) to 16.05% (EME). Our findings show that adopted EME for the use in soleus elicited twitch contraction show high to very high reliability, both absolute and relative, of all dependent variables.

COBISS.SI-ID: 1539807428In 2018, we successfully acquired the national applied project ARRS "Decomposition of skeletal muscle tensiomyography and identification of contractile parameters sensitive to muscular adaptations". Throughout the project, we will validate the process of decomposition of the mechanical muscle response to the responses of individual phenotypes of muscle fibers. According to bioptic samples, the contractile parameters of individual muscle fibers will be determined and then modeled in the response of the entire muscle. In the second phase, we will verify the validity of the decomposition to the study of postactivation potentiation, fatigue and atrophy. The findings will lead to the direct economic effects of the spin-off company TMG-BMC Ltd., which markets the tensiomyographic method, which is the product of Slovene science and which had achieved 110 scientific publications in SCI journals by 2019, an extremely high index of citation, )200 sold systems worldwide, the organization of the "International Society of Tensiomyography" and the new scientific journal "Advances in Skeletal Muscle Function Assessment".

COBISS.SI-ID: 2494931In young and older people skeletal muscle mass is reduced after as little as seven days of disuse. The declines in muscle mass after such short periods are of high clinical relevance, particularly in older people who show higher atrophy rate, and a slower, or even a complete lack of muscle mass recovery after disuse. We have privided new biomechanical marker of muscle atrophy provoked with 35-day bed rest. In three muscles we found earlier onset of muscle atrophy than observed with standard clinicla tools. e.g. sonography. Therefore, tensiomyography can detect early bed-rest-induced changes in muscle with higher sensitivity before overt architectural changes and atrophy can be detected.

COBISS.SI-ID: 2534355The desire and willingness to cooperate in the field of winter sports has always been present in the Balkan countries. Various forms of cooperation have long been present, however, limited at individual or, mostly institutional level. There have always been cooperation initiatives that would systemically link the ski experts of the Balkan Peninsula, but somehow they have not been realised. After the Slovenian team had returned from the Interski Congress in Argentina at the end of 2015, we were able to share our impressions and experience we had gained in Argentina with our Serbian colleagues in Kopaonik and Bosnian colleagues in Jahorina in the winter of 2016. This was the starting point from which the idea to organise a Balkan Ski Congress according to the Interski model arose. The main idea was to combine science, practice and education in the field of winter sports, to enhance interest in the wider scientific and professional public as well as to enrich ski companionship and to involve other professionals who have a common interest in the field of winter sports. This led to organising the SPE (Science, Practice & Education) Balkan Ski Conference. Members of our research program are the leading organizers of SPE BALKAN SKI congresses. Until today there were two Balkan ski congresses organised (Kopaonik, SRB, Jahorina, BIH, third is in progress - Rogla, SLO, 2020) where on average 160+ participatns share their research findings.
B.01 Organiser of a scientific meeting
COBISS.SI-ID: 1540427204The Institute for Kinesiology Research has received new facilities for the implementation of the IKARUS Laboratory and Mediterranean Health Center in the beginning of 2017. We offer services and activities related to popularization and promotion of kinesiology among individual target groups: athletes, recreationalists, elderly people, children, patients, companies , etc. In short, we are involved in the local and global strategy of increasing health and sports tourism. The Center supports the research activity of IKARUS in its premises and its equipment, and performs two accredited activities. It supports the international accreditation of the FIFA Medical Center of Excellence and the national accreditation of the Olympic Sports Medical and Therapeutic Center, which is carried out in cooperation with General Izola Hospital.
