Inter-segmental coordination variability during hopping and running on natural and synthetic turf surfaces.

An athlete's performance and musculoskeletal health hinges on their ability to adapt their movements to varying environmental constraints. However, research has yet to offer a thorough understanding of whether coordination variability is altered in response to different synthetic and natural turf surfaces. The purpose of this study was to investigate lower extremity coordination variability during hopping and running on four turf surfaces-three synthetic and one natural.

Video Analysis of Elite American Football Athletes During Vertical Jump.

Introduction: The National Football League (NFL) combine tests the athleticism of prospects competing for the draft. The vertical jump is included to test lower extremity power, yet the components which lead to the greatest performance remain elusive. Therefore, this study aimed to utilize a sample of elite athletes to analyze vertical jump components associated with increased performance and the relationship between vertical jump performance and rookie-year success.

A retrospective multi-site examination of chronic kidney disease using longitudinal laboratory results and metadata to identify clinical and financial risk.

Background: A retrospective observational study was conducted at 3 health care organizations to identify clinical gaps in care for patients with stage 3 or 4 chronic kidney disease (CKD), and financial opportunity from U.S. risk adjustment payment systems.

Perifollicular concentric granulomas: A clue to IgG4-related lymphadenopathy.

A 69-year-old with well-controlled HIV was evaluated for persistent cough, in the context of years of fatigue and influenza A infection 6 months prior. Chest CT and PET scans were notable for adenopathy concerning for a lymphoproliferative disorder. Radiologic studies also showed diffuse FDG uptake in the prostate, consistent with prostatitis.

Hip thrust and back squat training elicit similar gluteus muscle hypertrophy and transfer similarly to the deadlift.

We examined how set-volume equated resistance training using either the back squat (SQ) or hip thrust (HT) affected hypertrophy and various strength outcomes. Untrained college-aged participants were randomized into HT (n = 18) or SQ (n = 16) groups. Surface electromyograms (sEMG) from the right gluteus maximus and medius muscles were obtained during the first training session.
