The Influence of Sports‐Related Concussion on Cognition and Landing Biomechanics in Collegiate Athletes Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-07-10 Jason M. Avedesian, Tracey Covassin, Shelby Baez, Jennifer Nash, Janet S. Dufek
Injury surveillance data indicate that collegiate athletes are at greater risk for lower extremity (LE) injuries following sports‐related concussion (SRC). While the association between SRC and LE injury appears to be clinically relevant up to 1‐year post‐SRC, little evidence has been provided to determine possible mechanistic rationales. Thus, we aimed to compare collegiate athletes with a history

Association of Accelerometer‐Determined Physical Activity and Sedentary Behavior With the Gut Microbiome in Middle‐Aged Women: A Compositional Data Approach Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-07-01 Inmaculada Pérez‐Prieto, Jairo H. Migueles, Nerea M. Molina, Alberto Sola‐Leyva, Eduardo Salas‐Espejo, Riikka K. Arffman, Marjukka Nurkkala, Maisa Niemelä, Kreete Lüll, Elin Org, Stephen Franks, Juha S. Tapanainen, Andres Salumets, Terhi T. Piltonen, Francisco B. Ortega, Signe Altmäe
The beneficial effects of physical activity (PA) on gut microbiome have been reported, nevertheless the findings are inconsistent, with the main limitation of subjective methods for assessing PA. It is well accepted that using an objective assessment of PA reduces the measurement error and also allows objective assessment of sedentary behavior (SB).

Reduced Intratendinous Sliding in Achilles Tendinopathy During Active Plantarflexion Regardless of Horizontal Foot Position Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-06-20 Lecompte Laura, Crouzier Marion, Bogaerts Stijn, Scheys Lennart, Vanwanseele Benedicte
PurposeThe Achilles tendon consists of three subtendons with the ability to slide relative to each other. As optimal intratendinous sliding is thought to reduce the overall stress in the tendon, alterations in sliding behavior could potentially play a role in the development of Achilles tendinopathy. The aims of this study were to investigate the difference in intratendinous sliding within the Achilles

Epidemiology, etiology and prevention of injuries in competitive ice speed skating—limited current evidence, multiple future priorities: A scoping review Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-04-13 Matthias Hendricks, Evert Verhagen, Alexander T. M. van de Water
Long‐track and short‐track ice speed skating are integral to the Winter Olympics. The state of evidence‐based injury prevention in these sports is unclear. Our goals were to summarize the current scientific knowledge, to determine the state of research, and to highlight future research areas for injury prevention in ice speed skating. We conducted a scoping review, searching all injury and injury prevention

The effect of repeated concussions on clinical and neurocognitive symptom severity in different contact sports Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-04-13 Jennifer Glaser, Sarah Jaeckle, Thomas Beblo, Gerhard Mueller, Andreas M. Eidenmueller, Philipp Schulz, Ingo Schmehl, Witold Rogge, Karsten Hollander, Max Toepper, Andreas S. Gonschorek
IntroductionThe potential consequences of repeated concussions in sport are well documented. However, it remains unclear whether the cumulative impact of sports‐related concussions differs between different contact sports. Therefore, the aim of the current study was to investigate the cumulative effects of sports‐related concussions on clinical and neurocognitive health in different contact sports

Reference values for leg effort during incremental cycle ergometry in non‐trained healthy men and women, aged 19–85 Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-04-10 Abed A. Hijleh, Sophia Wang, Danilo C. Berton, Igor Neder‐Serafini, Sandra Vincent, Matthew James, Nicolle Domnik, Devin Phillips, Luiz E. Nery, Denis E. O'Donnell, J. Alberto Neder
Heightened sensation of leg effort contributes importantly to poor exercise tolerance in patient populations. We aim to provide a sex‐ and age‐adjusted frame of reference to judge symptom's normalcy across progressively higher exercise intensities during incremental exercise. Two‐hundred and seventy‐five non‐trained subjects (130 men) aged 19–85 prospectively underwent incremental cycle ergometry.

Distal hamstrings tendons mechanical properties at rest and contraction using free‐hand 3‐D ultrasonography Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-04-10 Chrysostomos Sahinis, Eleftherios Kellis
Tendon properties impact human locomotion, influencing sports performance, and injury prevention. Hamstrings play a crucial role in sprinting, particularly the biceps femoris long head (BFlh), which is prone to frequent injuries. It remains uncertain if BFlh exhibits distinct mechanical properties compared to other hamstring muscles. This study utilized free‐hand three‐dimensional ultrasound to assess

An integrative review of parent education approaches in sport: Considerations for program planning and evaluation Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-04-06 Fabrício João Milan, Camilla J. Knight, Lucas Machado de Oliveira, Vitor Ciampolini, Michel Milistetd
In recent years, there has been an increase in the delivery and evaluation of parent education programs within youth sport. Subsequently, some recent reviews of these programs have been conducted. However, one consistent issue across many of the programs and associated review papers is the lack of an appropriate evaluation framework to guide the planning or associated reporting of the outcomes of the
