Video analysis of head impacts in top-level female football players: a cohort study.

This study aimed at exploring the exposure of head impacts, i.e. headers and non-headers, in top-level female football players.

The Effect of an 8-Week Low- or High-Volume Protocol of the Adductor Strengthening Programme on Hip Adduction Strength in Female Football Players-A Randomized Trial.

The aim of this study was to investigate if an 8-week high-volume protocol of the Adductor Strengthening Programme was more effective than a low-volume protocol in increasing and maintaining isometric hip adduction strength in female football players. We randomized 52 players from the Norwegian women's 1st and 2nd division to a low-volume (220 reps/side) or high-volume (394 reps/side) group. Both groups performed an 8-week protocol of the Adductor Strengthening Programme and a 10-week maintenance protocol with 1 session/week (16 reps/side/session).

Long-term Prognosis of Patellar Tendinopathy (Jumper's Knee) in Young, Elite Volleyball Players: Tendon Changes 11 Years After Baseline.

Background: The long-term prognosis of jumper's knee and whether structural changes in the patellar tendon persist is unknown.

Purpose: To investigate whether limitations in knee function and structural changes persisted beyond the athletic career of young elite volleyball players.

Study Design: Cohort study; Level of evidence, 2.

Lower HAGOS subscale scores associated with a longer duration of groin problems in football players in the subsequent season.

Introduction: Groin injuries represent a considerable problem in football. Although the Adductor Strengthening Programme reduced groin injury risk, players can still experience groin symptoms throughout the season. This study aimed to determine whether preseason Copenhagen Hip and Groin Outcome Score (HAGOS) and a history of previous injury can identify individuals at risk of having a longer duration of groin problems the subsequent season, using an 'any physical complaint' definition of injury.
