Fontan palliation allows patients with "single ventricle" circulation to reach adulthood with an acceptable quality of life, although exercise tolerance is significantly reduced. To assess whether controlled respiratory training (CRT) increases cardiorespiratory performance. 16 Adolescent Fontan patients (age 17. 5 ± 3.8 years) were enrolled. Patients were divided into CRT group (n = 10) and control group (C group, n = 6). Maximal cardiopulmonary test (CPT) was repeated at the end of CRT in the CRT group and after an average time of 3 months in the C group...

This study investigated the effectiveness and safety of interval training during in-hospital treatment of patients with advanced heart failure. Twenty-four consecutive patients with advanced symptomatic heart failure who were referred for cardiac transplant evaluation were recruited. After performing aerobic exercise for approximate intensity, high-intensity interval training (HIIT) was performed. The protocol consisted of 3 or 4 sessions of 1-min high-intensity exercise aimed at 80% of peak VO2 or 80% heart rate reserve, followed by 4-min recovery periods of low intensity...

BACKGROUND: Standard treatment for locally advanced rectal cancer includes 5-6 weeks of neoadjuvant chemoradiotherapy (NACRT) followed by total mesorectal excision 6-8 weeks later. NACRT improves local disease control and surgical outcomes but also causes side effects including fatigue, diarrhea, hand-foot syndrome, and physical deconditioning that may impede quality of life (QoL), treatment completion, treatment response, and long-term prognosis. Interventions to improve treatment outcomes and manage side effects that are safe, tolerable and low-cost are highly desirable...

BACKGROUND: The late sodium current inhibitor ranolazine reverses the main electrophysiological and mechanical abnormalities of human hypertrophic cardiomyopathy (HCM) cardiomyocytes in vitro, suggesting potential clinical benefit. We aimed to assess the effect of ranolazine on functional capacity, symptomatic status, diastolic function, and arrhythmias in HCM. METHODS AND RESULTS: In this multicenter, double-blind, phase 2 study, 80 adult patients with nonobstructive HCM (age 53±14 years, 34 women) were randomly assigned to placebo (n=40) or ranolazine 1000 mg bid (n=40) for 5 months...

Cirrhosis patients have reduced peak aerobic power (peak VO2) that is associated with reduced survival. Supervised exercise training increases exercise tolerance. The effect of home-based exercise training (HET) in cirrhosis is unknown. The objective was to evaluate the safety and efficacy of 8 weeks of HET on peak VO2, 6-minute walk distance (6MWD), muscle mass, and quality of life in cirrhosis. Random assignment to 8 weeks of HET (moderate to high intensity cycling exercise, 3 days/week) or usual care. Exercise adherence defined as completing ≥80% training sessions...

OBJECTIVES: To investigate the acute and adaptation cardiovascular and metabolic training responses in people with Parkinson's disease (pwP). DESIGN: (1) A cross-sectional study of exercise response of pwP compared with sedentary controls and (2) an interventional study of exercise training in pwP. SETTING: Community leisure facilities. PARTICIPANTS: pwP (n=83) and sedentary controls (n=55). INTERVENTIONS: Study 1 included participants from a two-arm-parallel single-blind phase II randomised controlled trial (RCT), that undertook a baseline maximal incremental exercise test and study 2 included those randomised to the exercise group in the RCT, who completed a 6-month weekly exercise programme (n=37)...

OBJECTIVES: This study sought to investigate the association of left ventricular (LV) untwisting rate (UT) and E/e' ratio with the response of exercise capacity to spironolactone in heart failure with preserved ejection fraction (HFpEF). BACKGROUND: In most patients with HFpEF, LV filling abnormalities represent a central component in the development of dyspnea. LV diastolic filling is determined by the interplay of passive (LV stiffness and myocardial collagen content, reflected by E/e' ratio) and active myocardial properties (UT, a precursor to isovolumic pressure decay and contributor to diastolic suction)...

In recent decades, tremendous attention has been paid to the development of new electrode materials with high capacitance to meet the requirements of electrode materials in supercapacitors. Among vanadium oxides, VO2(A) has recently received increasing attention due to its unique layered structure, phase transformation and applications in Li-ion batteries. However, few studies have focused on the electrochemical properties of VO2(A) as electrochemical capacitors. Herein, we develop a facile hydrothermal method to prepare VO2(A)@C core-shell structured composites by carbonization of glucose in the presence of V2O5 nanowires...

AIMS: To establish the relationship between exercise training and clinical outcomes in people with type I diabetes. METHODS: Studies were identified through a MEDLINE search strategy, Cochrane Controlled Trials Registry, CINAHL, SPORTDiscus and Science Citation Index. The search strategy included a mix of key concepts related to exercise training; type 1 diabetes; glycaemic control for trials of exercise training in people with type 1 diabetes. Searches were limited to prospective randomized or controlled trials of exercise training in humans with type 1 diabetes lasting 12 weeks or more...

BACKGROUND: Exercise intensity is a particularly important determinant of physiological responses to exercise training in patients with acute myocardial infarction. Heart rate (HR) is commonly used as a practical way of prescribing and monitoring exercise as specific intensities based on linear relationship between the percentage of maximum heart rate (%HRmax) and the percentage of maximum oxygen consumption (%VO2max) regardless of age, sex or exercise mode. OBJECTIVE: To examine the change in variability in the correlation between %HRmax and %VO2maxafter acute myocardial infarction...

BACKGROUND: Ergogenic effects of caffeine (CAF) ingestion have been observed in different cycling exercise modes, and have been associated with alterations in ratings of perceived exertion (RPE). However, there has been little investigation of maximal oxygen uptake (VO2MAX) test outcomes. AIM: This study aimed to verify whether CAF may reduce RPE, thereby improving maximal incremental test (MIT) outcomes such as VO2MAX, time to exhaustion and peak power output (WPEAK)...

Background: Phosphodiesterase-5 inhibitors (PDE5i) have been shown to be beneficial for patients with pulmonary arterial hypertension. However, several studies would have documented a useful effect of PDE5i even for pulmonary hypertension secondary to left-sided chronic heart failure (CHF). Methods: We performed a meta-analysis including randomized controlled trials (RCTs) which had compared PDE5i (mostly sildenafil) and placebo in CHF patients. Results: Fourteen studies enrolling a total of 928 patients were incorporated in the meta-analysis...

Current evidence suggests that exercise training is beneficial in pulmonary arterial hypertension (PAH). Unfortunately, the standard supervised, hospital-based programs limit patient accessibility to this important intervention. Our proof-of-concept study aimed to provide insight into the usefulness of a prescribed walking regimen along with arginine supplementation to improve outcomes for patients with PAH. Twelve PAH patients (all women) in New York Heart Association (NYHA) functional class (FC) II (n = 7) or III (n = 5) and in stable condition for ≥ 3 months were enrolled...

[Purpose] Ventilatory limitation is a common problem in patients with chronic heart failure and pulmonary hypertension. Excess ventilation may arise from augmented ventilatory drive, over activity of chemoreceptors and muscle ergoreceptors, or premature onset of lactic acidosis. Exertional dyspnea can cause limitations in the activities of daily living and as a result, reduced quality of life for these patients. The aim of the present study was to evaluate the effect of cardiopulmonary rehabilitation program on ventilatory efficiency for these patients...

A growing number of adolescents are more sedentary and have fewer formal opportunities to participate in physical activity. With the mounting evidence that sedentary time has a negative impact on cardiometabolic profiles, health related fitness and physical activity, there is a pressing need to find an affordable adolescent physical activity intervention. One possible intervention that has been overlooked in the past is Boy Scouts of America. There are nearly 900,000 adolescent boys who participate in Boy Scouts in the United States...
