Strength deficits of the hamstrings following surgery on the anterior cruciate ligament: a case-control ­study of elite alpine ski racers

Background: Research to date clearly shows that injuries to the cruciate ligaments are a frequent occurrence in alpine ski racing. The hamstrings play an important role in protecting the anterior cruciate ligament (ACL). Here eccentric muscle activity, in particular, is of great significance as it plays a more important role in terms of duration and intensity than concentric muscle activity in alpine ski racing. The aim of this study was to establish whether the hamstrings of alpine ski racers show eccentric strength deficits following surgery on the anterior cruciate ligament.

Return to sport following hip arthroscopy for femoroacetabular impingement syndrome: return to sport rates and methodological considerations

Research studies on “Return to sport” (or return to play) have been recently published also in the field of hip arthroscopy for femoroacetabular impingement (FAI) in athletes. While most published papers discuss cases series (low level of evidence), Lasse Ishoi and the group of K. Thorborg and P. Hölmich (Copenhagen, Denmark) conducted one of the first prospective cohort studies on this topic. The paper has already been published in AJSM and the results were presented at the #SportSuisse2018 conference. One of the key methodological points is the definition of “Return to sport” when conducting studies: is it return to any sport at any level, or return to preinjury sport at preinjury level?

Responsiveness of the Star Excursion Balance Test on Firm and Unstable Underground

Objectives: To evaluate the responsiveness of the classic Star Excursion Balance Test (SEBT) and of a modified version performed on a soft surface (Airex Balance-Pad). The classic Star Excursion Balance Test is widely used in persons with chronic ankle instability. For the use in healthy athletes, the test can be made more difficult by performing it on a soft surface. Design: Pre-post study with balance assessment before and after a five-week intervention. Setting and participants: A convenience sample of 28 healthy adults performed both SEBT variants at baseline and after five weeks (9 sessions) of sensorimotor and strength training.
