Líkamsgerð og líkamlegt hreysti íslenskra badmintonspilara: Samanburður á afreks-, keppnis- og áhugamönnum

Badminton is a fast, interceptive, racquet sport and characterized by high-intensity intermittent actions. This work aimed to (i) analyze the anthropometric and physical fitness in Icelandic badminton players of different levels, (ii) develop a multidimensional test battery explaining from a multivariate perspective badminton performance (iii) and to examine the relationship of anthropometric and physical fitness variables and performance in badminton players. Thirty-five Icelandic badminton players (18.83 ± 2.04 years old; males, n=19; females, n=16) participated in this study. The badminton players were grouped in three groups in accordance with their playing level: elite (n=10), sub-elite (n=11) and recreational players (n=14). A multidimensional test battery was conducted were different parameters were measured and tested: height, weight, BMI, arm span, CMJ, medicine ball throw, grip strength, 505 test, reactive agility, shoulder flexibility and estimated VO2max. One-way ANOVA were carried out with LSD Post-hoc tests to know the differences between groups. A discriminant analysis was recorded to know which variables could predict badminton performance and, finally, Spearman’s rho correlations were performed to identify the relationship between variables. The results show that elite players have superior results (p<0.05) in four physical tests; CMJ, 505 test, grip strength test and estimated VO2max. No difference was detected between groups in shoulder flexibility, reactive agility or medicine ball throw. The predictive model classified 61.1% of male players correctly and 66.7% of female players correctly using only the VO2max results. A moderate (rc=-0.47) to very strong (rc=-0.83) correlation existed between four out of thirteen variables and badminton performance in males; medicine ball throw, CMJ, 505 test and estimated VO2max. For females, a moderate (rc=-0.51) to very strong (rc=-0.86) correlation existed between six out of thirteen variables and badminton performance; height, medicine ball throw, CMJ, grip strength, 505 test, and estimated VO2max. This study can give coaches helpful information regarding the anthropometric and physical characteristics of Icelandic badminton players which can assist them in training process of their athletes.Badminton er hröð íþrótt sem einkennist af miklum átökum með stuttri hvíld. Markmið þessarar rannsóknar var að (i) greina líkamsgerð og líkamlegt hreysti íslenskra badmintonspilara á mismunandi getustigum, (ii) þróa fjölþætt mælitæki sem gæti greint frammistöðu í badminton á mörgum sviðum (iii) og skoða tengslin á milli líkamsgerðar og líkamlegs hreystis á frammistöðu badmintonspilara. Þrjátíu og fimm íslenskir badmintonspilarar (18.83 ± 2.04 ára; karlar, n=19; konur, n=16) tóku þátt í þessari rannsókn. Badmintonspilurunum var getuskipt í þrjá hópa: afreks- (n=10), keppnis- (n=11) og áhugamannaspilarar (n=14). Fjölþátta mælitækið innihélt eftirfarandi breytur: hæð, þyngd, líkamssamsetningu, faðmlengd, lóðréttan stökkkraft (CMJ), kast með 2kg bolta, gripstyrk, 505 prófi, viðbragðssnerpu og áætlað VO2max. Einhliða dreifigreining var framkvæmd með LSD (e. least significant difference) eftir á prófunum til að kanna hvort það væri munur á milli hópa. Aðgerðargreining var gerð til að kanna hvaða breytur gæti spáð fyrir um frammistöðu í badminton og að lokum var stikalaus fylgnigreining framkvæmd til að kanna tengslin á milli breytanna. Niðurstöðurnar sýna að afreksspilarararnir eru að skora hærra (p
