Raziskovalno in strokovno delo v laboratoriju za biodinamiko. (Slovenian)

Research and expert work in the laboratory of biodynamics. (English)

In the Laboratory of Biodynamics, we have investigated endurance from different aspects, while also combining individual aspects of this ability into larger structures, using various integration models. Thus we have succeeded in defining specific speed and energy models that demonstrate this ability in different ways. This enables us to assess the activity of aerobic and anaerobic energy processes by measuring oxygen consumption. When oxygen consumption increases considerably, oxygen saturation in the muscles decreases. This is observed with a near-infrared spectroscope. In simulated high-altitude conditions, how the alpinist's body adjusts to such conditions during a high mountain expedition is observed, as well as how other athletes adjust to them during altitude training. Particular emphasis is put on endurance during climbing. To explain extremely long endurance, the metabolism of carbohydrates was observed by applying the method using stable carbon isotopes (13C). This enables investigation of the metabolism of fats as well as observation of the oxidation of endogenous and exogenous carbohydrates. Endurance during a higher but short strain is explored using the analysis of electrolytes: LA^-, H⁺, K⁺, Na⁺, Cl^- and Ca⁺. The observation of these electrolytes along with partial pressure of O2 and CO2 enable the assessment of the changes that define the efficiency of the respiratory system during exercise and, simultaneously, the electrolytic and acid-base imbalance. This knowledge can be used to help coaches in the training process by carrying out tests and analysing the completed training. [ABSTRACT FROM AUTHOR]

V laboratoriju za biodinamiko raziskujemo vzdržljivost z najrazličnejših vidikov, hkrati pa poskušamo z modeli (integrativno) združevati posamezne manjše dele te sposobnosti v večje dele. Tako smo definirali nekatere hitrostne in energijske modele, ki opazovano sposobnost kažejo različno. Pri tem lahko ocenimo aktivnost aerobnih in anaerobnih energijskih procesov z merjenjem porabe kisika. Pri zelo povečani porabi kisika prihaja do znižane saturacije kisika v mišicah. Opazujemo jo z bližnje infrardečim spektroskopom. S simulacijo okoliščin na povišani nadmorski legi opazujemo prilagoditev organizma alpinistov na odpravah v visoka gorstva ali pri drugih športnikih ob višinskih pripravah. Posebej ugotavljamo vzdržljivost med plezanjem. Za pojasnitev super- dolgotrajne vzdržljivosti opazujemo presnovo ogljikovih hidratov s pomočjo metod uporabe stabilnih izotopov ogljika (13C). Ta nam omogoča tudi opazovanje presnove maščob, predvsem pa lahko ločeno opazujemo oksidacijo endogenih in eksogenih ogljikovih hidratov. Vzdržljivost pri višjih, toda kratkotrajnejših naporih opazujemo s pomočjo analize elektrolitov: LA-, H+, K+, Na+, Cl-, in Ca+. Opazovanje že naštetih elektrolitov kot tudi delnih tlakov O2 in CO2 nam omogoča oceno sprememb, ki opredelijo učinkovitost dihalnega sistema med naporom, hkrati pa tudi porušenje elektrolitskega in acidobaznega ravnovesja. Uporaba pridobljenega vedenja nam omogoča pomoč trenerjem v vadbenem procesu, s pomočjo testiranj in analize opravljene vadbe. [ABSTRACT FROM AUTHOR]
