Abstract [en]

The purpose of this study was to determine the test-retest reliability of 1080 Quantum syncro (1080 Motion AB, Stockholm, Sweden) using a test method of squat jumps through Average power calculations. 19 professional ice hockey players aged 18-35 who play in the Swedish second division (Allsvenskan) participated in the study. The test subjects perform a test and a retest of squat jumps at six different loads between 25-84 kg in random order with a standardized rest of about 45 sec. All test participants were also required to perform a standardized warm-up for each test and a preparatory jump series. Results were obtained from the test devices' measurement units, and then analyzed using the statistical methods Pearson's correlation (r value), Significance of r (p-value) and Standard Deviation. The results of individual test subjects showed excellent correlation r = 0.983 - 0.999 (p = 0.001) and a Standard Deviation = 147 w - 243 w. At group level, high to excellent correlation was shown r = 0.863-0.925 (p = 0.001) and slightly higher standard deviation at test 2, -1 w – 19 w relative to test 1. Based on the results shown in this study, 1080 Quantum syncro can safely provide reliable test-retest results.

Abstract [sv]

Syftet med denna studie var att fastställa test-retest reliabiliteten av 1080 Quantum syncro (1080 Motion AB, Stockholm, Sweden) med en testmetod bestående av squat jumps genom beräkningar av medeleffekt. 19 professionella ishockeyspelare i åldrarna 18-35 år som spelar i den svenska andra divisionen (Allsvenskan) deltog i studien. Testpersonerna utförde ett test och ett retest av squat-jumps på sex olika belastningar mellan 25-84 kg i slumpad ordningsföljd med en standardiserad vila av ca 45 sek. Alla testdeltagare fick även utföra en standardiserad uppvärmning inför varje test samt en förberedande hopp serie. Resultat hämtades från testutrustningens mätenheter och analyserades sedan med de statistiska metoderna Pearson’s korrelation (r-värde), Singnifikans av r-värdet (p-value) samt Standard Deviation. Resultaten hos enskilda testpersoner uppvisade utmärkt korrelation r=0,983 - 0,999 (p=0,001) samt en Standard Deviation=147 w - 243 w. På gruppnivå uppvisades hög till utmärkt korrelation r=0,863-0,925 (p=0,001) samt något högre Standard Deviation vid Test 2 -1 w – 19 w i förhållande till Test 1. Utifrån de resultat som har visat sig i denna studie kan 1080 Quantum syncro med säkerhet frambringa tillförlitliga test-retest resultat.
