Article Abstract
Background: Exercise and statins reduce cardiovascular disease (CVD). Exercise capacity may be assessed using cardiopulmonary exercise testing (CPET). Whether statin medication is associated with CPET parameters is unclear. We investigated if statins are related with exercise capacity during CPET in the general population.
Methods: Cross-sectional data of two independent cohorts of the Study of Health in Pomerania (SHIP) were merged (n = 3,500; 50% males). Oxygen consumption (VO2) at peak exercise (VO2peak) and anaerobic threshold (VO2@AT) was assessed during symptom-limited CPET. Two linear regression models related VO2peak with statin usage were calculated. Model 1 adjusted for age, sex, previous myocardial infarction, and physical inactivity and model 2 additionally for body mass index, smoking, hypertension, diabetes and estimated glomerular filtration rate. Propensity score matching was used for validation.
Results: Statin usage was associated with lower VO2peak (no statin: 2336; 95%-confidence interval [CI]: 2287-2,385 vs. statin 2090; 95%-CI: 2,031-2149 ml/min; P < .0001) and VO2@AT (no statin: 1,172; 95%-CI: 1,142-1,202 vs. statin: 1,111; 95%-CI: 1,075-1,147 ml/min; P = .0061) in males but not females (VO2peak: no statin: 1,467; 95%-CI: 1,417-1,517 vs. statin: 1,503; 95%-CI: 1,426-1,579 ml/min; P = 1.00 and VO2@AT: no statin: 854; 95%-CI: 824-885 vs. statin 864; 95%-CI: 817-911 ml/min; P = 1.00). Model 2 revealed similar results. Propensity scores analysis confirmed the results.
Conclusion: In the general population present statin medication was related with impaired exercise capacity in males but not females. Sex specific effects of statins on cardiopulmonary exercise capacity deserve further research.

Oxidative stress has attracted attention as an indicator of exercise load. Minimizing the impact on the body is essential during underwater treadmill exercise. Here, we conducted an exploratory study of the effects of dermal suction, which has been reported to improve blood flow in healthy dogs, prior to underwater treadmill exercise.

This study investigated whether, 24 hours after the exercise-induced muscle damage protocol (EIMDP), melatonin administration performed 30 minutes prior to the protocol exhibited responses about inflammatory and redox status. Control (CG), exercised (EG), and exercised+melatonin (EMG) groups were submitted to the incremental test through swimming exercise to determine the intensity of the maximal aerobic capacity (iMAC). Melatonin (10 mg kg) was administered, and after 30 min, the EIMDP was induced through swimming exercise (10 sets of 1 min with 30-s interval at 120% of iMAC, followed by 20 minutes continuous exercise at 100% of iMAC).

Baroreflex activation therapy (BAT) improves functional status, quality of life, and exercise capacity in patients with heart failure with reduced ejection fraction; however, its direct effects on reversing adverse cardiac remodeling as assessed by improvements in cardiac structure, function, and coupling with the arterial system remain unclear. We present 2 cases of patients who initially presented with decompensated heart failure, and despite initial medical therapy and continued outpatient follow-up, were unable to tolerate full escalation of guideline-directed medical therapy. The patients remained symptomatic, with high biomarker levels, poor functional capacity, severe heart failure symptoms, and objectively had decreased stroke volume, low left ventricular ejection fraction, and high left ventricular mass.

Background: Nutrition underpins athletic performance, enhancing training, reducing injury risk, and accelerating recovery. In the event of an injury, performance dietitians (PDs) and nutritionists' (PNs) play a vital role by tailoring nutritional strategies to support tissue repair, optimize athlete's recoveries, and return to play.
Objectives: This study explored nutritional strategies recommended and employed by Irish PDs and PNs to assess, manage, and support athletes during the initial stages of sports-related injuries.

Objective: To explore the exercise capacity in obese patients with severe obstructive sleep apnea syndrome (OSAS) through cardiopulmonary exercise test (CPET).
Methods: In this cross-sectional study, patients with simple obesity (36 cases) and obese patients with severe OSAS (45 cases) admitted to the Department of Rehabilitation Medicine and the Department of General Practice of the Affiliated Wuxi People's Hospital of Nanjing Medical University from September 2019 to January 2024 were collected. Additionally, we included 33 patients (BMI<28 kg/m,AHI<5/hour) as a control group.
