Abstract (english)
Paralumbar muscle performance and fatigue were evaluated by measuring electromagnetic activity during entire body vibration (EBV) in 44 healthy subjects. Physical fitness of subjects was estimated on a 5-degree scale. Electric activity was recorded in 200 seconds with 1 kHz sampling on the Biopac Student Lab during EBV. Data were used to produce time series for two vectors of the phase space and spatial axis: X (left-right), Y (up-down) and Z (ventral-dorsal). Time series were evaluated by calculating fractal dimension by the R/S algorithm. Movement of the electric field along the Y-axis showed changes (up-down) extracted in the first and second quarter of the measurement (p=0.02 and p=0.03, respectively). These changes were not specific for gender but showed dependence on subject age and fitness. The fractal dimension values by the R/S algorithm were larger in female subjects. Results suggested the electric field changes during EBV in the up-down direction to contain information on muscular performance and fatigue, not dependent on gender, but on the age and degree of overall physical fitness.
Abstract (croatian)
Istraživanje električnog polja paralumbalne muskulature kao pokazatelja umaranja provedeno je na 44 zdrava ispitanika, pri čemu je utreniranost njihove paralumbalne muskulature procijenjena anamnestički ljestvicom od 5 stupnjeva. Električna aktivnost snimana je uređajem Biopac Student Lab i uporabom tri para elektroda postavljenih duž osi faznog prostora. Iz prikupljenih podataka izostavljeni su dijelovi koji odgovaraju QRS kompleksu EKG-a i rekonstruirani sljedovi pet različitih načina mjerenja električne aktivnosti, pri čemu su za prva tri izdvojeni zapisi za svaku os. Za os X lijevo i desno, za os Y gore i dolje te za os Z naprijed i nazad, a izračunata su i dva vektora. Iz tako dobivenih vremenskih serija računala se fraktalna dimenzija R/S algoritmom. Od rezultata izračunom fraktal-ne dimenzije zapisa R/S algoritmom izdvaja se kretanje električnog polja duž osi Y (gore-dolje) u prvoj i drugoj četvrtini mjerenja (p=0,02 odnosno p=0,03). Rezultati su se pokazali neovisnima o spolu, ali ovisnima o godinama i utreniranosti ispitanika. Vrijednosti fraktalne dimenzije po R/S algoritmu u žena su bile veće. Navedeno upućuje na to da podaci o kretanju položaja mjerenja duž osi Y (gore-dolje) u sebi sadrže informacije o načinu umaranja muskulature koje nisu ovisne o spolu, nego o dobi i stupnju utreniranosti.
