Background: The Star Excursion Balance Test (SEBT) is commonly used to assess dynamic postural balance both in clinical practice and research. The aim of our study was to assess the within-session relative and absolute reliability of participants' performance of the modified SEBT (mSEBT) using a single practice trial in healthy elite athletes who were familiar with the test.
Methods: An intra-session repeated-measures design was used to investigate the relative and absolute reliability of participants' (healthy athletes partaking in sports at a high-risk of ankle sprain injury) performance of the mSEBT. A total of 122 healthy elite athletes from soccer ( = 73), basketball ( = 15), and volleyball ( = 34) performed one practice trial and three test trials within one session, in three directions (anterior, postero-medial, and postero-lateral), for both legs. Intraclass correlation coefficient (ICC), standard error of measurement (SEM), and smallest detectable change at a 95% confidence were calculated.
Results: We found a good to excellent relative within-session intra-rater reliability between the three trials on specified directions, with an ICC (3,1) from 0.90 to 0.95. SEM and SDC for normalized and composite scores, for both legs ranged from 0.91 to 2.86, and 2.54 to 7.94, respectively.
Conclusions: In conclusion, we report good to excellent within-session reliability for the mSEBT. Our results confirm that the test can be reliably used with only one practice trial in healthy elite athletes familiar with the test.

This study aimed to examine the differences in shoulder ultrasonographic parameters between overhead aquatic athletes and their relationship with shoulder pain. Sixty-four healthy junior subjects ( = 128 shoulders) participated in the study, including 17 healthy controls, 25 elite junior swimmers, and 22 elite junior water polo players. An ultrasonographic study of the shoulder was carried out to measure the thickness of the rotator cuff structures in sex- and age-paired groups.

Recent empirical investigations reinforce the understanding of a profound interconnection between metabolic functions and Obstructive Sleep Apnea-hypopnea Syndrome (OSAHS). This study identifies distinctive miRNA signatures in OSAHS with Metabolic Syndrome (Mets) patients from healthy subjects, that could serve as diagnostic biomarkers or describe differential molecular mechanisms with potential therapeutic implications. In this study, OSAHS with MetS patients showed significantly higher Apnea Hyponea Index(AHI), but lower oxygen desaturation index(ODI 4/h) and minimum pulse oxygen saturation(SpO).

Background: Dietary intake is a modifiable factor linked to short-term and long-term health. The Healthy Eating Index (HEI) is an objective measure to assess diet quality and population-level comparisons, like military to civilian.
Objectives: This study aimed to characterize diet quality of early-career and mid-career female soldiers compared with that of age-matches and sex-matched civilians and to link indicators of cardiometabolic disease risk to dietary outcomes and health status.

Mitochondrial quality control is paramount for cellular development, with mitochondrial electron flow (Mito-EF) playing a central role in maintaining mitochondrial homeostasis. However, unlike visible protein entities, which can be monitored through chemical biotechnology, regulating mitochondrial quality control by invisible entities such as Mito-EF has remained elusive. Here, a Mito-EF tracker (Mito-EFT) with a four-pronged probe design is presented to elucidate the dynamic mechanisms of Mito-EF's involvement in mitochondrial quality control.

Objective: The purpose of this systematic review is to evaluate the original peer-reviewed studies on athletes who developed myocarditis after coronavirus disease (COVID-19) infection or after COVID-19 mRNA vaccination. Both entities likely have an immunologic component. We discuss elite, professional, college, and adolescent athletes.
