Purpose: The use of a fixed theoretical-proportional-factor (TPF) is one of the indirect highest-oxygen-consumptions (HOC) assessment methods, but it may not accurately reflect the physiological differences across various sports (cycling-triathlon-running-football-multisport). The aim of this study is to evaluate the variability of TPF across different sports, proposing a series of sport-specific new TPF values for more accurate HOC estimation.
Methods: A sample of 340 adults (26.
Background: Sports supplements (SSs) are widely used among team sport athletes; however, evidence supporting the use of SSs among football referees at the elite level is scarce. The aim of the present study was to analyze the consumption of SSs among referees with respect to their level of competition and referee type (main referees (MRs) vs. assistant referees (ARs)).

Objective: This systematic review aimed to compile the scientific evidence available for addressing the question "What dietary strategies, including dietary and supplementation approaches, can improve sports performance, recovery, and health status in female athletes and other physically active women?"
Data Sources: The Pubmed, Web of Science, and Scopus databases were searched.
Data Extraction: The review process involved a comprehensive search strategy using keywords connected by Boolean connectors.

The aim of this study was to analyse the variables that determine the performance of the Optimist class during a regatta in different wind conditions. A total of 203 elite sailors of the Optimist class (121 boys and 82 girls) participated in the study. According to their ranking in the regatta, the sample was divided into four performance groups.

However, most of the studies were realized in male athletes with limited evidence in female athletes. Thus, the aim of this study was to explore the acute ingestion of BRJ in female rugby players.

The aims of the present study were to evaluate the current scientific evidence of the effects of PNM on pain and physical capabilities in neuromusculoskeletal injuries.
Methods: Data sources: There was used the PRISMA protocol.
This study examines the injuries suffered by players (n=166) of the Spanish national men's under-18 and under-20 rugby teams between 2015 and 2017, and identifies the actions involved in their occurrence. All injuries (total n=78) sustained during matches and training were recorded as recommended by World Rugby, and injury incidence rates per 1000 player-hours (ph) calculated for both types of activity. Injuries occurred more commonly during matches than during training (incidence 105.

However, while myocardial adaptations of the left heart are well described, remodelling of the right heart and its impact on the development of arrhythmias is still debated. To conduct a systematic review on right ventricle (RV) and right atrium (RA) structural and functional changes in athletes who participate in long-term endurance training.

Purpose: the aim of the present study was to analyse the pattern of dietary supplements (DS) consumption on federated rugby players, including the analysis of differences based on the sex and competitive level (professional vs. amateurs).
Material And Methods: 144 rugby players (83 male and 61 female), of whom 69 were professionals and 75 amateurs, were recruited for the study.
Dietary nitrate (NO) supplementation, which can enhance performance in exercise settings involving repeated high-intensity efforts, has been linked to improved skeletal muscle contractile function. Although muscular strength is an important component of explosive movements and sport-specific skills, few studies have quantified indices of muscular strength following NO supplementation, particularly isokinetic assessments at different angular velocities. We performed a systematic review and meta-analysis to determine whether dietary NO supplementation improves peak torque, as assessed by the gold standard method of isokinetic dynamometry, and if this effect was linked to the angular velocity imposed during the assessment.

Actually, the fundamental principles behind the measurement of respiratory gas exchange (RGE) have not changed for a century. It was used a manual Douglas bag method together with separate chemical analyses.

Objective: To investigate the incidence of injuries sustained by players on the Spanish national under-18 rugby team during their participation in 4 European championships (2014-2017) and the types of play in which they occurred.
Design: Cohort study.
Objective: In this cross-sectional study, we compared Spanish division one (n = 114) and division two (n = 80) soccer players in terms of their cardio-respiratory response during recovery following a maximum laboratory effort test.
Approach: Following the maximum laboratory effort protocol, we measured oxygen consumption ([Formula: see text]), heart rate (HR), and ventilation ([Formula: see text]) during recovery.
Main Results: Over the first 60 s of recovery, no significant differences were seen in either [Formula: see text] (28.
Background: Corticosteroid infiltration (CI) is commonly used for treatment of plantar fasciosis. In recent years, however, interest has grown in the use of intratissue percutaneous electrolysis (EPI) for the treatment of tendinopathies. The aim of our study was to compare the effectiveness of the above techniques in the treatment of plantar fasciosis.
