dc.description.abstractAbstrakt Hensikt: Hovedmålet med denne studien var å estimere ytre treningsmengde i en typisk uke (Mikrosyklus) med en kamp for kvinnelige eliteseriespillere. Et sekundært mål var å undersøke om det var forskjeller in disse parameterne mellom posisjoner og treningsøkter. Tjue-en kvinnelige fotballspillere (22.6 ± 3.3 år, 170.7 ± 5.9 cm, 66.9 ± 7 kg) fra et elitelag i Norge deltok i studien. Syv microsykluser med komplett data ble samlet inn med et globalt navigerings satelittsystem (GNSS) med GPS data samlet på 18 Hz. Variablene som ble inkludert for å estimere ytre belastning var felttid (FT; m), total distanse (TD; m), høy intesitetsløping (HSR: 12.5-19.0 km·t-1), veldig høy intensitetsløping (VHSR: 19.0-22.5 km·t-1), sprinter (SPR: >22.5 km·h-1), akselerasjon (ACC: >3 m·s-2) og deselerasjon (DEC: >3 m·s-2). Ukentlig treningsmengde ble sammenlignet med treningsmengde opplevd under kamp. For denne dataen brukte vi gjennomsnittlig ytrebelastning for syv kamper. En «mixed linear model» ble brukt for å sammenligne total akkumulert ytre treningsmengde mellom posisjoner og treningsøkter, separat. Resultat: MD-3 hadde høyest belastning, og MD-5 hadde lavest. Den akkumulerte belastningen for HSR, SPR, ACC og DEC for trening i microsyklusen var en del høyere sammenlignet med kamp, med unntak av defensive midtbanespillere defensive midtbanespillere som hadde høyere kampdata for HSR og SPR. Defensive midtbanespillere hadde høyere verdier for TD og HSR, og sentrale angrepsspillere hadde høyest for SPR og ACC. Konklusjon: Funnene demonstrerer at ytre belastning av en mikrosyklus varierer basert på posisjon og type økt. Spesifikt er det større variasjoner i belastning mellom posisjoner i kamp sammenlignet med trening. Denne informasjonen kan være nyttig for trenere når de planlegger treningsbelastning for en mikrosyklus og gir mulighet til å tilpasse posisjon spesifikk belastning fra kamp til treningsukene.
dc.description.abstractAbstract Purpose: The primary aim of this study was to quantify the external training load in a typical week (Microcycle) with one match for elite female soccer players. A secondary aim was to determine whether there were differences in these parameters between playing position and training sessions. Method: Twenty-one female soccer players (22.6 ± 3.3 years, 170.7 ± 5.9 cm, 66.9 ± 7.0 kg) from one elite team in Norway took part in the study. Seven microcycles with complete data from training sessions and matches were included in the analysis. The one-weekly-match-microcycle consist of the following: Match day (MD), MD+1 is the day after the match, MD-5 is five days before the next match and the start of the microcycle, MD-4 is four days before match etc. The data was collected with Global Navigation Satellite System (GNSS) with GPS data collected at 18 Hz. The variables included to quantify external load were total distance covered (TD; m), distances in high-speed running (HSR: 12.5-19.0 km·h-1), very-high speed running (VHSR: 19.0-22.5 km·h-1), sprinting (SPR: >22.5 km·h-1), acceleration (ACC: >3 m·s-2) and deceleration (DEC: >-3 m·s-2). Weekly training load was compared with external load experienced during matches. For this purpose, we used the average external load of seven matches. A linear mixed model was used to compare the total accumulated external load between positions and sessions, separately. Results: Overall, MD-3 had the highest load, and MD-5 had the lowest. The accumulated HSR, SPR, ACC and DEC load during training in the microcycle were a lot higher compared to match data. An exception was seen for defensive midfielder which had higher match data for HSR and SPR. Defensive midfielders had highest values for TD and HSR whilst central forwards had highest SPR and ACC. Conclusion: External load of a microcycle varied based on playing position and session type, specifically bigger variations in load between positions in matches compared to trainings. This information may be useful for practitioners when planning training load a microcycle and gives the opportunity to adapt position-specific load from match demands to the training week.
