Abstract
Cilj istraživanja: Prema dosadašnjim spoznajama, ograničena su saznanja o ulozi snage i izdržljivosti dišne muskulature na fizičku izdržljivost sportaša u anaerobnom dijelu metabolizma do maksimalnog opterećenja. Cilj ovog istraživanja jest ispitati povezanost inspiratorne snage/izdržljivosti dišnih mišića s ventilacijskim i metaboličkim parametrima od anaerobnog praga do maksimalnog opterećenja tijekom kardiopulmonalnog testa fizičkim opterećenjem (CPET) na pokretnoj traci u skupini vrhunskih sportaša. Nacrt studije: Studija je ustrojena kao presječna studija u kojoj je proučavana povezanost snage i izdržljivosti inspiratornih mišića s ventilacijskim i metaboličkim parametrima tijekom CPETa u okviru redovitog sportskog pregleda, uz antropometrijska mjerenja, laboratorijske analize urina, te hematološke i biokemijske analize krvi. Ispitanici i metode: U istraživanje je uključeno sedamdeset vrhunskih zdravih profesionalnih sportaša timskih sportova (košarka i rukomet) u dobi od 16 do 36 godina. Istraživanje je provedeno u kliničkom CPET laboratoriju i uključuje detaljan klinički pregled, antropometrijska mjerenja, hematološku i biokemijsku analizu krvi te analizu urina, testiranje snage i izdržljivosti inspiratornih mišića, spirometriju, EKG i CPET. Analizirani su ventilacijski i metabolički parametri pri drugom ventilacijskom pragu (VT2) i pri maksimalnom opterećenju te njihova promjena, u odnosu na snagu (PImax) i izdržljivost (Tlim) dišnih mišića. Tlim je u ovom istraživanju mjeren kao vrijeme tijekom kojeg je ispitanik disao održavajući tlak od najmanje 80 % PImax. Rezultati: Razlika u parcijalnom tlaku kisika na kraju izdisaja (ΔPETO2) između VT2 i maksimalnog opterećenja bila je značajno i neovisno povezana sa srčanom frekvencijom (HR), sistoličkim krvnim tlakom u mirovanju (BP), PImax i bezmasnom tjelesnom masom (LBM) (r2 = 0,26, p = 0,016; multivarijatna regresijska analiza). Razlika u izdahnutom ugljičnom dioksidu (ΔVCO2) između VT2 i maksimalnog opterećenja bila je značajno i neovisno povezana s indeksom tjelesne mase (BMI), HR i BP u mirovanju i PImax (r2 = 0,25, p = 0,022; multivarijatna regresijska analiza). Zaključak: U skupini ispitivanih vrhunskih profesionalnih sportaša snaga (uz još neke varijable), ali ne i izdržljivost inspiratornih mišića značajno utječe na fizičku izdržljivost u zoni gotovo isključivo anaerobnog metabolizma te bi njeno testiranje i treniranje trebalo postati dio rutinske pripreme sportaša.
Abstract (english)
Objectives: According to prior knowledge, there are limited insights about the role of respiratory muscle strength and endurance on athletes’ performance during the anaerobic part of metabolism until maximal exertion. The aim of this study was to examine the association between the strength/endurance of inspiratory muscles and ventilatory and metabolic parameters measured from anaerobic threshold up to the maximum load during the cardiopulmonary exercise test (CPET) on a treadmill in a group of healthy professional athletes. Study design: The study used a cross-sectional association design for strength and endurance of inspiratory muscles with the CPET ventilatory and metabolic parameters determined on the checkup day together with the anthropometric measurements and hematology, biochemistry and urine analyses. Subjects and methods: Seventy highly trained healthy professional athletes of team sports (basketball and handball) aged 16 – 36 years were recruited. The study was conducted in a clinical CPET laboratory and included detailed clinical examination, anthropometric measurements, urine and blood analyses (hematology and biochemistry), inspiratory muscle strength and endurance testing, spirometry, electrocardiogram and CPET. Ventilatory and metabolic parameters at second ventilatory threshold (VT2), at maximal effort, and their differences were tested for association with inspiratory muscle strength (PImax) and endurance (Tlim) measures. Tlim was for this study measured as the time to maintain inspiration at or above 80 % of PImax. Results: The difference in end-tidal oxygen tension (ΔPETO2) between VT2 and maximal effort was significantly and independently associated with resting heart rate (HR), resting systolic blood pressure (BP), PImax and lean body mass (LBM) (r2 = 0,26, p = 0,016; multivariate regression analysis). The difference in exhaled carbon dioxide (ΔVCO2) between VT2 and maximal effort was significantly and independently associated with body mass index (BMI), resting HR, resting systolic BP, and PImax (r2 = 0,25, p = 0,022; multivariate regression analysis). Conclusion: We found in our group of professional athletes that it is the inspiratory muscle strength (with some other variables) and not endurance that significantly affects the performance of these athletes in the part of most exclusively anaerobic metabolism and that it should be tested and trained systematically.
