Sports, Journal Year: 2025, Volume and Issue: 13(2), P. 40 - 40

Published: Feb. 5, 2025

Maximal oxygen uptake (V.O2max) assesses athletic performance; however, its values are inconsistent in post-COVID-19 athletes. This study aimed to analyze the dynamics of V.O2max Observational studies were identified by screening PubMed database published up 17 July 2023. The initial electronic search found 320 studies. Of these, 26 employing cardiopulmonary exercise test (CPET) assess aerobic fitness selected. 2625 pooled athletes, 1464 infected and considered as group, either asymptomatic or symptomatic, while remaining 1161, who uninfected had results prior infection, defined infection-free group. Age differently distributed between athletes those without infection (p = 0.03 both). Persistent symptoms 8 mL/Kg/min lower than 0.04). In addition, post-infected underwent CPET after 12 weeks showed a significant reduction 2.9 according increase body mass index (BMI). analysis that was reduced post-COVID-19. negatively correlated with BMI at weeks, suggesting persist beyond affecting return-to-play.

Sports, Journal Year: 2025, Volume and Issue: 13(2), P. 51 - 51

Published: Feb. 10, 2025

Body composition and cardiopulmonary exercise testing (CPET) are vital for optimizing sports performance, but the correlations between them still underexplored. Our study aimed to investigate relationships body specific CPET variables describing physical fitness in young athletes, also adjusting age height, a less-studied, female population. Seventy players participated our (age: 16.10 ± 1.63 y). After determining using dual-energy X-ray absorptiometry, we conducted treadmill-based maximal-intensity CPET. Data were analyzed R multivariate linear regression, accounting height as confounders. Lean mass (LBM), fat (BFM), bone mineral content (BMC) showed no effect on resting, maximum, or recovery heart rates correlation with resting maximal lactate values. LBM positively correlated maximum ventilation (VE-max) (Est: 1.3 × 10−3; SE: 6.1 10−4; p < 0.05) absolute oxygen consumption (VO2abs-max) 7.710−5; 6.9 10−6; 0.001)—with an influencing factor VE-max VO2abs-max. Conversely, BFM negative relative (VO2rel-max) −4.8 1.2 0.001). Moreover, BMC negatively duration −2.2 8.0 10−5; 0.01; Est: −3.2 1.4 factor. findings indicate complex parameters, providing important information analysis of individual ergospirometric data. results draw attention fact that is more precise than weight evaluation athletes’ fitness.

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 COVID-19 mRNA vaccination. Both entities likely have an immunologic component. We discuss elite, professional, college, and adolescent athletes. are generally young healthy, representing a distinctive population group that differs from general population. This includes diagnosis myocarditis, incidence, complications, prognosis, return-to-play guidance for sports medicine clinicians coaches. surveyed PUBMED, Embase, Web Science databases relevant articles in English language published onset pandemic until April 2023. Included were observational case series. Excluded individual reports small series with incomplete data. resulting search yielded 30 articles.

Published: Aug. 26, 2023

This study assessed the experiences of elite aquatic athletes with coronavirus disease 2019 (COVID-19) during first World Championship conducted without social distancing and an isolation "bubble". An online questionnaire was completed by 812 (22.7 ± 5.9 years, 467 females) to provide data on demographics, sports activity, severe acute respiratory syndrome 2 (SARS-CoV-2) infection rates, symptoms, reinfection, vaccination status, psychological aspects. The answers revealed that 49.4% had experienced SARS-CoV-2 infection. rates varied significantly across different sports, open water swimmers having lowest (28%) polo players (67%) artistic (61%) highest (p < 0.0001). majority reported mild (51%) or moderate (27%) while 16% remained asymptomatic. Reinfection occurred in 13%, 10% initial infections led long COVID, fatigue (65%) shortness breath (48%) being most common long-term symptoms. Significantly, 92% received at least two vaccine doses a positive experience (median score 8 out 10 for each shot). Mood changes subjective performance drops correlated overall scores (rho: 0.617, p 0.0001, rho: 0.466, respectively). In conclusion, benign course despite relatively high rate. provides valuable insights into COVID-19 athletes. findings emphasize importance initiatives, monitoring well-being need fortify athletes' resilience face future health challenges.

Published: Feb. 1, 2024

Abstract The aim of this study was to characterize the right ventricular (RV) contraction pattern and its associations with exercise capacity in a large cohort adolescent athletes using resting three-dimensional echocardiography (3DE). We enrolled 215 (16±1 years, 169 males, 12±6 hours training/week) compared them 38 age sex-matched healthy, sedentary adolescents. measured 3DE-derived biventricular ejection fractions (EF). also determined relative contributions longitudinal EF (LEF/RVEF) radial (REF/RVEF) RVEF. Same-day cardiopulmonary testing performed calculate VO2/kg. Both LV RVEFs were significantly lower (athletes vs. controls; LVEF: 57±4 vs 61±3, RVEF: 55±5 60±5%, p<0.001). Interestingly, while contribution shortening global RV reduced (REF/RVEF: 0.40±0.10 0.49±0.06, p<0.001), higher (LEF/RVEF: 0.45±0.08 0.40±0.07, p<0.01). supernormal correlated weakly VO2/kg (r=0.138, P=0.044). Similarly adult athlete’s heart, cardiac adaptation comprises volumes functional measures shortening. Characteristic exercise-induced structural changes are already present adolescence.

The aims of this study were to examine the effect SARS-CoV-2 infection on cardiorespiratory fitness (CRF) and time-trial performance in vaccinated well-trained young kayak athletes. This is a longitudinal observational study. Sixteen (7 male, 9 female) kayakers underwent body composition assessment, maximal graded exercise test, 1000-m tests 21.9 ± 1.7 days before 66.0 2.2 after infection. perception training load was quantified with Borg's CR-10 scale return sport period. There significant decreases peak oxygen uptake (-9.7%; size [ES] =1.38), pulse (-5.7%; ES =0.96), heart rate (-1.9%; =0.61). Peak minute ventilation, ventilation/carbon dioxide production slope unchanged compared pre-infection values.
