Dietary antioxidant capacity is inversely associated with F2- isoprostane and body fat percentage in elite soccer referees.

Background Dietary antioxidant Capacity (DaC) has been used as a tool for predicting plasma and dietary antioxidant concentrations. However, the DaC association with oxidative stress (OS) and body composition parameters is an unexplored area, mainly in physically active individuals. Given the potential for increased OS in physically active individuals, it becomes crucial to investigate this association.

Use of phase angle as an indicator of overtraining in sport and physical training.

The use of bioelectrical impedance analysis (BIA) is now well established in healthcare as an essential support tool for patient management in various clinical settings. Its use in sports is rapidly expanding due to the valuable insights it offers, helping to better structure athletes' diets and training programs, thereby optimizing their performance. In the context of sport, however, there is a consensus regarding the importance of proper interpretation of BIA-derived data, which cannot be limited to mere estimation of body composition.

The Role of Ion-Transporting Proteins on Crosstalk Between the Skeletal Muscle and Central Nervous Systems Elicited by Physical Exercise.

A paradigm shift in the understanding of bidirectional interactions between peripheral and central nervous systems is essential for development of rehabilitation and preventive interventions based on physical exercise. Although a causal relationship has not been completely established, modulation of voltage-dependent ion channels (Ca, Cl, K, Na, lactate-, H) in skeletal and neuronal cells provides opportunities to maintain force production during exercise and reduce the risk of disease. However, there are caveats to consider when interpreting the effects of physical exercise on this bidirectional axis, since exercise protocol details (e.

Anterior Cruciate Ligament Reconstruction and Concomitant Focal Cartilage Lesions: A Systematic Review and Meta-Analysis of Prognosis after Surgical Treatment.

Objective: To synthesize available evidence on the impact of concomitant focal cartilage lesions and their surgical treatment on clinical outcomes in the setting of anterior cruciate ligament (ACL)-reconstruction at short (6-36 months) and midterm (3-8 years) follow-up.

Design: Original level 1 or 2 studies comparing any patient-reported or objective outcomes in ACL-reconstructed patients (1) with and without concomitant focal cartilage lesion(s) or (2) after any type of cartilage surgical treatment were considered for inclusion. Systematic searches were conducted in MEDLINE via Ovid, Cochrane Library, EMBASE via OvidSP, and Web of Science.

Overweight and obesity among Israeli adolescents and the risk for serious morbidity in early young adulthood: a nationwide retrospective cohort study.

Background: Morbidities related to obesity are usually associated with its severity and duration. Yet, the onset of serious morbidities in early adulthood among otherwise healthy adolescents with obesity is understudied. We aimed to investigate the association between adolescent BMI and serious morbidities before age 25 years.

A Novel Machine Learning Model to Predict Revision ACL Reconstruction Failure in the MARS Cohort.

Background: As machine learning becomes increasingly utilized in orthopaedic clinical research, the application of machine learning methodology to cohort data from the Multicenter ACL Revision Study (MARS) presents a valuable opportunity to translate data into patient-specific insights.

Purpose: To apply novel machine learning methodology to MARS cohort data to determine a predictive model of revision anterior cruciate ligament reconstruction (rACLR) graft failure and features most predictive of failure.

Study Design: Cohort study; Level of evidence, 3.

An observational study: Correlation between self-perceived readiness and physical performance in healthy individuals.

Introduction: In complex environments, individuals need to anticipate and react to stimuli by integrating complex systems and skills. Identifying the perceptual-cognitive, physical, and health characteristics that afford effective performance is necessary for developing training and readiness strategies. Measuring readiness by establishing a relationship between the Acute Readiness Monitoring Scale (ARMS) and performance during perceptual-cognitive tasks is essential.

Optimal levels of sleep, sedentary behaviour, and physical activity needed to support cognitive function in children of the early years.

Background: Sleep, sedentary behaviour, physical activity, and the composition of these movement behaviours across the 24-h day are associated with cognitive function in early years children. This study used a Goldilocks day compositional data analysis approach to identify the optimal duration of sleep, sedentary behaviour, light physical activity, and moderate-to-vigorous physical activity associated with desired cognitive function outcomes in early years children.

Methods: This cross-sectional study included 858 children aged 2.

No effect of grape juice on exercise-induced muscle damage or performance in male runners: a randomized, placebo-controlled, triple-blind clinical trial.

This study aimed to verify the effect of grape juice () intake on exercise-induced muscle damage (EIMD) and exercise performance parameters (5 km running time-trial (TT), running economy, and countermovement jump (CMJ)). Twenty trained male runners were randomized into two blinded groups and consumed either placebo ( = 9) or grape juice ( = 11) for six consecutive days (600 mL/day). On the fourth day, the participants performed a downhill running (-15%) at speed that elicited 70% V̇Omax for 20 min, to induce muscle damage, followed by assessment of running economy, 5 km TT, and CMJ tests.

Preparing the soil: Adjusting the metabolic health of patients with chronic wounds and musculoskeletal diseases.

In recent years, systemic inflammation has emerged as a pivotal player in the development and progression of various degenerative diseases. This complex, chronic inflammatory state, often undetected, can have far-reaching consequences for the body's physiology. At the molecular level, markers such as C-reactive protein, cytokines and other inflammatory mediators serve as indicators of systemic inflammation and often act as predictors of numerous musculoskeletal diseases and even certain forms of cancer.
