Special Issue Information

Dear Colleagues,

Sports cardiology is a dynamic and rapidly evolving field that bridges cardiovascular medicine and athletic performance. With growing participation in recreational and competitive sports across all ages, there is an increasing need to optimize cardiovascular health, manage inherited and acquired heart diseases, and provide safe return-to-play strategies. Innovations in diagnostic imaging, mobile health technologies, personalized exercise prescriptions, and preventive cardiology are transforming the landscape. Furthermore, the focus is expanding toward cardiac rehabilitation in athletes and differentiation of athlete’s heart from pathology.

A particularly important and emerging area of interest is pediatric fitness, where early cardiovascular assessment and promotion of physical activity in children and adolescents are crucial for lifelong heart health. Research into pediatric exercise testing, sports participation guidelines, and risk stratification for inherited cardiac conditions in young athletes is shaping preventive strategies and personalized interventions.

This Special Issue will explore the latest advancements and future directions in sports cardiology through original research, reviews, and clinical insights. Our goal is to enhance understanding, promote individualized care, and inspire innovation at the intersection of cardiovascular science, pediatric health, and sports medicine.

Topics will include the following:

  • Cardiovascular screening in athletes;
  • Management of arrhythmias in sports;
  • Mobile health and remote monitoring;
  • Personalized cardiac rehabilitation for athletes;
  • Sudden cardiac arrest and prevention strategies;
  • Exercise prescription in special cardiac populations;
  • Pediatric fitness and cardiovascular health.

Background: After a warm-up and before the start of sports competition, athletes often take a break. During this break, the effects of the warm-up (e.g., capillary vasodilation) may diminish. The aim of this study was to compare cardiorespiratory responses during high-intensity physical exercise, either preceded or not preceded by post-warm-up breathing, using an additional respiratory dead space volume mask (ARDSv). Methods: The study included 20 trained cyclists. Each participant completed two 3 min tests at an intensity of 110% of their maximal power, determined during a progressive test. A standardised warm-up preceded each 3 min test. Following the warm-up, there was an 8 min passive rest period. During this break, participants either breathed using ARDSv or breathed normally (non-ARDSv). The volume of the ARDSv mask was 1000 mL. Cardiorespiratory parameters were measured during the tests, including mean: oxygen uptake (VO2av), respiratory exchange ratio (RERav), respiratory rate (RRav), tidal volume (TVav), stroke volume (SVav), and rating of perceived exertion (RPE). Results: VO2peak was higher in participants breathing using ARDSv compared to non-ARDSv (4.22 ± 0.40 [CI: 4.03–4.41] vs. 3.98 ± 0.42 [CI: 3.79–4.18]; p = 0.002; t = 3.56; d = 0.585). Additionally, RERav (1.08 ± 0.06 [CI: 1.06–1.11] vs. 1.13 ± 0.06 [CI: 1.11–1.16]; p = 0.008; t = 2.96; d = 0.833) and RPE (18.0 ± 1.7 [CI: 17.3–18.8] vs. 18.9 ± 1.1 [CI: 18.4–19.4]; p = 0.009; Z = 2.61; r = 0.583) were lower in participants breathing using ARDSv compared to non-ARDSv. Conclusions: Breathing using ARDSv between warm-up and high-intensity exercise increases oxygen uptake and reduces perceived exertion, likely through peripheral mechanisms. These effects suggest practical applications in competitive sports and provide directions for further mechanistic research. Full article

Cardiopulmonary exercise testing (CPET) is a gold standard to assess cardiorespiratory fitness (CRF). CRF varied through the lifespan, increasing in children until early adulthood and then gradually declining. Reference values for CPET are used to check whether the child’s CRF falls within the normal range. The differences between directly measured and normative age-adjusted exercise data may suggest pathology and are helpful during the diagnostic process. Deriving reference values for children is particularly challenging. Moreover, many children participate in sports, some at an advanced/elite level, which translates into specific adaptations in CPET. The ATS/ACCP statement on CPET presented a checklist that should be followed when reporting reference values. However, the checklist originally focused on adults. This aggravates the quality of reporting pediatric reference values for CPET, making between-studies comparisons difficult. This review (1) presents a step-by-step protocol to fulfill all requirements from the ATS/ACCP statement in the pediatric population, and (2) summarizes the key challenges in deriving reference values for CPET in children, especially among pediatric athletes. Additional recommendations to enrich the quality of reporting reference values for CPET in pediatric athletes were also discussed. Full article

Background: Reduced cardiorespiratory fitness along with poor exercise tolerance are regarded as potential morbidity and mortality predictors within the heart failure (HF) population. Despite the reliability and accuracy of the gold-standard cardiopulmonary exercise test (CPET) for assessing cardiorespiratory fitness, its complexity and tolerability issues among HF patients mean that the 6 min walk test (6MWT) is a cost-saving and well-tolerated complementary assessment. We aimed to systematically review the validity, reliability, and safety of the 6MWT compared to CPET for patients with HF. Methods: This study is a systematic review and meta-analysis. Embase, Medline, and Scopus were searched from inception to November 2023. We applied Fisher’s z-transformation to correlation coefficients and pooled effects under a random-effects model; heterogeneity (I2), leave-one-out sensitivity, and Egger’s test were reported. Results: Twenty studies were finally included, involving 5379 HF participants. A significant moderately strong positive correlation was shown between the 6MWT distance and CPET peak oxygen consumption: (r) = 0.62, 95% CI 0.58–0.66; I2 = 56.95%; p < 0.001. The results showed an excellent test–retest reliability, with a pooled intraclass correlation coefficient of 0.93 (95% CI 0.89–0.95; I2 = 92.06%; p < 0.001). A pooled weighted mean difference of 15.5 m (95% CI 10.2–20.8) was found for the learning effect between the first and second 6MWT. Although some patients required rest stops or reported symptoms such as fatigue or dyspnea, no 6MWTs were terminated due to serious adverse events. Conclusions: Compared with CPET, the 6MWT distance demonstrated a moderately strong correlation with peak VO2, excellent test–retest reliability, and a small learning effect. The 6MWT can therefore complement CPET or serve as a pragmatic alternative when CPET is not feasible; it does not replace comprehensive CPET assessment. Full article
