Det finns bristande tillgång på studier som undersökt Change of Direction Speed (CODS) och Repeated Sprint Ability (RSA) förmåga att förutspå fysisk prestation under match mätt med GPS-system. Syftet med studien var att undersöka två fälttester, 20 meter Repeated Sprint Ability test (RSA20) och Modifierat-Change of Direction Speed test (M-CODS) och dess samband till fysisk prestation under match: medeldistans (MD), acceleration (ACC), deceleration (DEC), högintensiva löpningar (HL), väldigt högintensiva löpningar (VHL), sprinter och maximal hastighet (MH) under matcher mätt med GPS-system (S5, 100Hz, CatapultSports, Australien). Under försäsongen utförde tio manliga elitfotbollsspelare (25.5±2.1 y/o, 78.8±3.6 kg,181.34±.9 cm) två fälttester som sedan jämfördes med fysisk prestation under match. Studien fann moderata signifikanta samband då p<0.05 mellan bästa tiden på RSA20 (RSA20bäst) och accelerationer inkluderat med decelerationer (ACC+DEC) (r=-0.643) samt medeltiden på RSA20 (RSA20medel) och medelantalet sprinter (r=-0.638). Studiens slutsats var att de utförda fälttesterna inte bör användas i syfte att indikera prestation till följd av inre och yttre faktorers påverkan. / There is an inadequate amount of studies which have examined Change Of Direction Speed test (CODS) and Repeated Sprint Ability test (RSA) possibility to indicate match-related physical performance, measured with GPS-system. The aim of this study was to examine the relationship between two field test, 20 meter Repeated Sprint Ability (RSA20), Modified-Change of Direction Speed test (M-CODS) and match related physical performance: average distance (MD), acceleration (ACC), deceleration (DEC), high intensity running (HL), very high intensity running (VHL), sprints and peak velocity (MH) during games recorded with GPS system (S5, 100Hz, MinimaxX, CatapultsSports, Australia). During the pre-season, ten Swedish male elite soccer players (25.5±2.1 y/o, 78.8±3.6 kg,181.34±.9 cm), completed the two field tests. The results of the two test were later compared and related to in-game physical match performance. This study found moderate significant relationships between best time on RSA20 (RSA20best) and acceleration added with deceleration (ACC+DEC) (r=-0.643) and sprints (r=-0.638). The conclusion of this study was that these analyzed field tests should not be used with the intention to indicate physical match related physical performance, due to the major influence of internal and external factors during gameplay.
