Bakgrund: Ljumskskador, ljumsk- och höftsmärta hos fotbollsspelare har oftast samband med minskat rörelseomfång i höfter, svaghet i bål och höftmuskulatur. Risk för ljumsksmärta ökar hos idrottare som inte tränar skadepreventivt. Syfte: Att undersöka om ett preventionsprogram med sex övningar för styrka och rörlighet kan minska förekomsten av ljumsksmärta hos herrfotbollsspelare. Material och metod: En kvantitativ experimentell fallstudie med kontrollgrupp, som utfördes med 14 herrfotbollslag (7 lag interventionsgrupp, 7 lag kontrollgrupp). I studien deltog 514 manliga fotbollspelare i åldern mellan 15-47 år. Resultat: I interventionsgruppen som genomförde ett preventionsprogram var antalet spelare med ljumsksmärta oförändrat, medan antalet deltagare med ljumsksmärta i kontrollgruppen ökade. Konklusion: Ett preventionsprogram med övningar för styrka och rörlighet kan förebygga förekomst av ljumsksmärta hos herrfotbollsspelare. Nyckelord: Fotboll, prevention, ljumskskada, ljumsksmärta, höftsmärta / Background:Groin injuries, groin pain and hip pain for soccer players are often associated with decreased range of motion (ROM) in the hip, weakness in abdominal muscles and poor hip muscles. The risk of groinpain increases for athletes who do not practice any preventing exercises. Objective:To research if an injury prevention program with six exercises for strength and mobility has any effect on groin pain and hip pain for male soccer players. Measures and Methods: Quantitative experimental study with control group. 14 male soccer teams participated (7 teams in intervention group, 7 teams in control group). In the study 514 male soccer players participated, in the age of 15-47 years. Result: In the intervention group who practiced the prevention program did not the number of players with groinpain increased, compared with the control group where the numbers of players with grioinpain increased. Conclusion: An injury prevention program for male soccer players with exercises for strength and mobility could prevent increase of groinpain among male soccer players. Keywords: Soccer, prevention, groin injury, groin pain, hip pain

Abstract Decreased adductor muscle strength has been shown to be a risk factor for the development of future groin injury. The purpose of this study was therefore to examine standard values of isometric adductor muscle strength in Swedish male soccer and to map any differences in muscle strength between non-injured players and previously injured players. Twenty-one male soccer players were included in the study. A handheld dynamometer was used to record maximal isometric adductor muscle strength. The average value for isometric adductor muscle strength for all included players was 2,709 N/kg [± 0,37 SD]. Average values for non-injured and previously injured players were 2,716 N/kg [± 0,41 SD] and 2,537 N/kg [± 0,25 SD] respectively. The average value for the contralateral, non-injured side within the previously injured players was 2,86 N/kg [± 0,43 SD]. The difference in muscle strength between previously injured players and non-injured players was not statistically significant (p = .162). Conversely the difference between the non-injured side and the injured side in previously injured players was statistically significant (p = .018). Future studies should focus on including players of different levels to conclude whether the differences observed in this study is present regardless of the level of play.
