| Sažetak | Istražili smo povezanost snage udisajnih mišića s parametrima plućne funkcije u mirovanju te metaboličkim i kardiopulmološkim parametrima tijekom progresivnog testa opterećenja. Na šezdeset četiri zdrava sportaša (dob:22,4±4,6godina; TM:84,9±10,3 kg; TV:187,9±10,3 cm) visokointenzivnih sportova izvedeni su: spirometrijsko testiranje, test snage dišnih mišića i progresivni kardiopulmološki test u naporu. Utvrdili smo da nema statistički značajne povezanosti između snage udisajnih mišića (PImax) i broja udaha na anaerobnom pragu (BRanp; r=-0,17; p=,179), maksimalnog broja udaha (BRmax; r=-0,08; p=,541), broja otkucaja srca na anaerobnom pragu (HRanp; r=0,06; p=,662), maksimalnog broja otkucaja srca (HRmax; r=0,1; p=,421), primitka kisika na anaerobnom pragu (VO2anp; r=0,18; p=,146), relativnog primitka kisika na anaerobnom pragu (VO2ranp; r=0,03; p=,843), maksimalnog primitka kisika (VO2max; r=0,15; p=,240), maksimalnog relativnog primitka kisika (VO2rmax; r=-0,01; p=,919), forsiranog izdisajnog volumena u prvoj sekundi (FEV1; r=0,11; p=,383) i vršnog izdisajnog protoka u sekundi (PEF; r=0,06; p=,663). Zaključujemo da snaga udisajnih mišića vjerojatno nema utjecaj na parametre aerobne izdržljivosti u kratkotrajnom progresivnom testu opterećenja kod sportaša visokointenzivnih sportova. |
| Sažetak (engleski) | We investigated relation of inspiratory muscle strength with parameters of lung function during rest and metabolic and cardiopulmonary parameters during progressive exercise stress testing. Sixty four healthy athletes (age:22,4±4,6years; body mass:84,9±10,3 kg; body height:187,9±10,3 cm) competing in high intensity sports performed spirometry, inspiratory muscle strength test and a progressive cardiopulmonary exercise test. No associations between inspiratory muscle strength (PImax) and breathing rate at the anaerobic treshold (BRanp; r=-0,17; p=,179), maximal breathing rate (BRmax; r=-0,08; p=,541), heart rate at the anaerobic treshold (HRanp; r=0,06; p=,662), maximal heart rate (HRmax; r=0,1; p=,421), oxygen consumption at the anaerobic treshold (VO2anp; r=0,18; p=,146), relative oxygen consumption at the anaerobic treshold (VO2ranp; r=0,03; p=,843), maximal oxygen consumption (VO2max; r=0,15; p=,240), maximal relative oxygen consumption (VO2rmax; r=-0,01; p=,919), forced expiratory volume in first second (FEV1; r=0,11; p=,383) and peak expiratory flow in one second (PEF; r=0,06; p=,663) were noted. This suggests that inspiratory muscle strength probably does not influence parameters of aerobic endurance during a short progressive cardiopulmonary exercise test in athletes competing in high intensity sports. |
