Abstract [en]

Background: The need to find the underlying causes to handball injuries and to develop injury prevention programs is great. In other sports a relationship between maximal oxygen uptake (VO2 max) and injury have been seen.

Purpose: To examine the relationship between VO2 max and/or lactate threshold and injuries in elite handball players.

Methods: A prospective, non experimental correlational study was conducted. Thirty elite handball players and handball high school players were included. Injuries and test results for VO2-max, lactate threshold and potential confounders ( re-injury of the previous injury, re- injury of previous injury of the lower limb, age, BMI and legs and core strength for the high school players) were registered during the season 2014-2015. A bivariate analysis using Spearman's rank correlation calculation was conducted. Twenty-six respectively 11 of the players had data on VO2-max, respectively lactate threshold. Confounders that showed connection with injuries or injuries in the lower extremity were analyzed for the bivariate correlation with VO2-max and lactate threshold.

Results: No significant correlation was found between VO2-max respectively lactate threshold and injury. Significant correlations were seen between previous injury respectively previous injury to the lower extremity and to get a re-injury. A significant correlation were seen between re-injury of a previous injury in the lower limb and VO2-max.

Conclusions: Significant associations were seen between re- injury of earlier injury and between re-injury of the lower extremity and VO2-max and should therefore be considered in the clinical practice. Larger studies are needed to clarify the relationship between VO2-max and lactate threshold and injuries. 

Abstract [sv]

Bakgrund: Behovet att hitta bakomliggande orsaker till handbollsskador för att kunna utforma skadepreventiva åtgärder är stort. I andra idrotter har ett samband mellan maximal syreupptagningsförmåga (VO2-max) och skador kunnat ses.

Syfte: Att undersöka samband mellan VO2-max och/eller laktattröskelvärde och skador hos elithandbollspelare.

Metod: En prospektiv icke experimentell sambandsstudie utfördes. Trettio elithandbollsspelare och handbollsgymnasiespelare inkluderades. Skador och testresultat för VO2-max och laktattröskel samt tänkbara konfounders (återskada av tidigare generell skada, återskada av tidigare skada i nedre extremitet, ålder, BMI och ben och bålstyrka för gymnasiespelarna) registrerades under matchsäsongen 2014-2015. En bivariat analys med Spearmans rangkorrelationsberäkning utfördes. Tjugosex respektive 11 av spelarna hade data på VO2-max respektive laktattröskelvärde. Konfounders som visade samband med generella skador eller skador i nedre extremiteten analyserades bivariat för samband med VO2-max och laktattröskelvärde.

Resultat: Inga signifikanta samband fanns mellan VO2-max respektive laktattröskelvärde och skador. Signifikanta samband fanns för tidigare generella skador respektive tidigare skada i nedre extremiteten och att återfå densamma samt mellan återskada av tidigare skada i nedre extremiteten och VO2-max.

Konklusion: Signifikanta samband fanns för återskada av tidigare skada samt mellan återskada i nedre extremiteten och VO2-max vilket bör beaktas i den kliniska vardagen. Större studier behövs för att klargöra det sambandet mellan VO2-max respektive laktattröskel och skador.
