Respiratory Patterns in Different Sports - Differences Between Judo, Boxing and Swimming : Undergraduate Thesis

Spirometrija se smatra zlatnim standardom mjerenja plućne funkcije ili testom disanja koji mjeri volumen zraka koji pojedinac udahne ili izdahne u jedinici vremena. Respiratorni obrasci kod sportaša dokazano se razlikuju od onih u populaciji nesportaša zbog prilagodbe intenzivnoj fizičkoj aktivnosti. Ovo istraživanje imalo je za cilj utvrditi razlike između judaša, boksača i plivača u funkcionalnim respiratornim parametrima. Radi se o tzv. unakrsnom istraživanju provedenom tokom šestomjesečnog perioda u Centru za medicinu sporta "Diomed Larem" u Splitu, Hrvatska. Uzorak ispitanika obuhvatio je 49 sportaša, dobi 20.5 ± 2.9 godina iz tri različita sporta: judo, boks i plivanje. Svi sportaši izvršili su testiranje spirometrije koristeći spirometar microQuark PC-a proizvođača Cosmed. Procijenjen je forsirani vitalni kapacitet (FVC), forsirani ekspiracijski volumen u jednoj sekundi (FEV1), forsirani ekspiracijski volumen u 1 s / omjer forsiranog vitalnog kapaciteta (FEV1 / FVC), forsirani ekspiracijski protok između 25% i 75% (FEF25-75), maksimalni ekspiracijski protok na 25% (MEF25) i maksimalni ekspiracijski protok pri 50% (MEF50). Sportaši su uspoređivani primjenom ANOVE s Bonferroni post-hoc analizom za više usporedbi. Analizom varijance ustanovile su se značajne razlike samo u izmjerenom forsiranom vitalnom kapacitetu (FVC / L, p <0.01, ηp2 = 0,2) i relativnim (postotnim) vrijednostima forsiranog vitalnog kapaciteta (FVC%, p = 0.03, ηp2 = 0.14). Plivači su imali značajno veće vrijednosti FVC / L (p = 0.03) i FVC% (p <0.01) u usporedbi s judašima, ali ne i u usporedbi s boksačima FVC / L (p = 0.07) i FVC% (p = 0.05).Spirometry is considered as a gold standard pulmonary function or breathing test that measures how an individual inhales or exhales volumes of air as a function of time. Respiratory patterns in trained individuals are proven to be different from those of normal populations due to the adaptation to intensive physical activity. This investigation aimed to determine the differences between judo, boxing, and swimming athletes in functional respiratory parameters. This was a cross-sectional investigation conducted during a six-month period in the Center for Sports Medicine „Diomed Larem“. Sample of subjects included 49 athletes, aged 20.5±2.9 years from three different sports: judo, boxing, and swimming. All athletes performed spirometry testing using microQuark PC Based Spirometer by Cosmed. To assess measured and percentages of predicted forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory volume in 1 s/forced vital capacity ratio (FEV1/FVC), forced expiratory flow between 25% and 75% (FEF25-75), maximal expiratory flow at 25% (MEF25), and maximal expiratory flow at 50% (MEF50) values. Athletes were compared using one way ANOVA with Bonferroni post-hoc analysis for multiple comparisons. Analysis of variance revealed significant differences only in measured forced expiratory volume (FVC/L, p<0.01, ηp2=0.2) and percentages of predicted forced expiratory volume (FVC%, p=0.03, ηp2=0.14). Swimmers had significantly higher values of FVC/L (p=0.03) and FVC% (p
