Dunkin, JE and Phillips, SM. The effect of a carbohydrate mouth rinse on upper-body muscular strength and endurance. J Strength Cond Res 31(7): 1948-1953, 2017-Carbohydrate (CHO) mouth rinsing rapidly increases corticomotor output and maximal muscle force production, which could enhance muscular strength and endurance during resistance exercise. However, previous research has found no effect of CHO rinsing on muscular strength or endurance. The current study altered the CHO rinse composition and frequency and the muscular endurance test to further investigate the effects of a CHO mouth rinse on upper-body muscular strength and endurance...

Aerobic exercise confers sustainable protection against cardiac hypertrophy and heart failure (HF). Nitric oxide synthase (NOS) and nitric oxide (NO) are known to play an important role in exercise-mediated cardioprotection, but the mechanism of NOS/NO stimulation during exercise remains unclear. The aim of this study is to determine the role of β3-adrenergic receptors (β3-ARs), NOS activation, and NO metabolites (nitrite and nitrosothiols) in the sustained cardioprotective effects of aerobic exercise. An HF model was constructed by transverse aortic constriction (TAC)...

Chronic heart failure is characterized by autonomic imbalance, cardiac dysfunction and arrhythmogenesis. It has been shown that exercise training (ExT) improves central nervous system oxidative stress, autonomic control and cardiac function in heart failure with reduced ejection fraction (HFrEF), however to date no comprehensive studies have addressed the effects of ExT, if any, on oxidative stress in brainstem cardiovascular areas, cardiac autonomic balance, arrhythmogenesis and cardiac function in heart failure with preserved ejection fraction (HFpEF)...

Both the aging process and heart failure (HF) syndrome are characterized by a dramatic reduction of aerobic capacity. Significant decreases in muscle mass and strength are also common. Few HF training studies have included meaningful numbers of older individuals, especially those greater than 80 years of age and older women with HF with reduced ejection fraction. The modest data available suggest similar benefits in older patients and excellent safety. Resistance training may provide additional benefit...

Heart failure (HF) with abnormal left ventricular (LV) ejection fraction should be identified and treated. Treat hypertension with diuretics, angiotensin-converting enzyme (ACE) inhibitors, and β-blockers. Treat myocardial ischemia with nitrates and β-blockers. Treat volume overload and HF with diuretics. Treat HF with ACE inhibitors and β-blockers. Sacubitril/valsartan may be used instead of an ACE inhibitor or ARB in chronic symptomatic HF and abnormal LV ejection fraction. Add isosorbide dinitrate/hydralazine in African Americans with class II to IV HF treated with diuretics, ACE inhibitors, and β-blockers...

Heart failure (HF) consists the fastest growing clinical cardiac disease. HF patients are categorized on the basis of underlying left ventricular ejection fraction (LVEF) into HF with preserved EF (HFpEF), reduced LVEF (HFrEF), and mid-range LVEF (HFmrEF). While LVEF is the most commonly used surrogate marker of left ventricular (LV) systolic function, the implementation of two-dimensional echocardiography in estimating this parameter imposes certain caveats on current HF classification. Most importantly, LVEF could fluctuate in repeated measurements or even recover after treatment, thus blunting the borders between proposed categories of HF and enabling upward classification of patients...

We previously reported that facilitating the clearance of damaged mitochondria through macroautophagy/autophagy protects against acute myocardial infarction. Here we characterized the impact of exercise, a safe strategy against cardiovascular disease, on cardiac autophagy and its contribution to mitochondrial quality control, bioenergetics and oxidative damage in a post-myocardial infarction-induced heart failure animal model. We found that failing hearts displayed reduced autophagic flux depicted by accumulation of autophagy-related markers and loss of responsiveness to chloroquine treatment at 4 and 12 weeks after myocardial infarction...

Background Exercise training as part of a comprehensive cardiac rehabilitation is recommended for patients with cardiac heart failure. It is a valuable method for the improvement of exercise tolerance. Some studies reported a similar improvement with quadricipital electrical myostimulation, but the effect of combined exercise training and electrical myostimulation in cardiac heart failure has not been yet evaluated in a large prospective multicentre study. Purpose The aim of this study was to determine whether the addition of low frequency electrical myostimulation to exercise training may improve exercise capacity and/or muscular strength in cardiac heart failure patients...

Aerobic exercise training is an effective therapy to improve peak aerobic power (peak VO2) in individuals with hypertension (HTN, AHA/ACC class A) and heart failure patients with preserved ejection fraction (HFpEF). High nitrate containing beetroot juice (BRJ) also improves sub-maximal endurance and decreases blood pressure in both HTN and HFpEF. We hypothesized that combining an aerobic exercise and dietary nitrate intervention would result in additive or even synergistic positive effects on exercise tolerance and blood pressure in HTN or HFpEF...

The difference between men and women is clear even just by looking at an electrocardiogram: females present higher resting heart rate, a shorter QRS complex length and greater corrected QT interval. The development of these differences from pubertal age onward suggests that sexual hormones play a key role, although their effect is far from being completely understood. Different incidences between sexes have been reported for many arrhythmias, both ventricular and supraventricular, and also for sudden cardiac death...

Cardiac function, skeletal (soleus) muscle oxidative metabolism and the effects of exercise training were evaluated in a transgenic murine model (Tgαq*44) of chronic heart failure (CHF) during the critical period between the occurrence of an impairment of cardiac function and the stage at which overt cardiac failure ensues (i.e. from 10 to 12 months of age). Forty-eight Tgαq*44 mice and 43 wild-type (WT) FVB controls were randomly assigned to control groups and to groups undergoing 2 months of intense exercise training (spontaneous running on a instrumented wheel)...

Heart failure (HF) is a common end point for numerous cardiovascular conditions, including coronary artery disease, valvular disease, and hypertension. HF predominantly affects older individuals (aged ≥70 years), particularly those living in developed countries. The pathophysiological sequelae of HF progression have a substantial negative effect on physical function. Diminished physical function in older patients with HF, which is the result of combined disease-related and age-related effects, has important implications on health...

Heart failure with preserved ejection fraction (HFpEF) is a common disease with high incidence and increasing prevalence. Patients suffer from functional limitation, poor health-related quality of life, and reduced prognosis. A pilot study in a smaller group of HFpEF patients showed that structured, supervised exercise training (ET) improves maximal exercise capacity, diastolic function, and physical quality of life. However, the long-term effects of ET on patient-related outcomes remain unclear in HFpEF. The primary objective of the Exercise training in Diastolic Heart Failure (Ex-DHF) trial is to investigate whether a 12 month supervised ET can improve a clinically meaningful composite outcome score in HFpEF patients...

Overweight and obesity are well-established risk factors for most cardiovascular diseases (CVD), including coronary heart disease (CHD), heart failure (HF), and atrial fibrillation. Despite the strong link between excess adiposity and risk of CVD, growing evidence has demonstrated an obesity paradox in patients with CVD. This phenomenon is characterized by a better prognosis in overweight and mildly obese CVD patients than their leaner counterparts. Moreover, the worst outcomes are often incurred by underweight CVD patients, followed by those of normal weight or severely obese...

There is substantial causal and consequential interaction between the ever-growing heart failure and renal failure patients. Half of the patients with heart failure (HF) have preserved left ventricular ejection fraction (HFpEF), which is difficult to diagnose and rising in prevalence relative to HF with reduced EF (HFpEF). To date, only weight reduction, exercise training, and diuretics have been shown to improve exercise tolerance and morbidity in HFpEF. This review aims to establish the baseline kidney-related concepts specific to the diagnosis and treatment of HFpEF patients and the different aspects of HFpEF and HFpEF in the clinical setting...
