BACKGROUND: Associated pulmonary hypertension (APH) is frequently observed in fibrosing interstitial pneumonias (FIP), such as idiopathic pulmonary fibrosis (IPF). APH is associated with worse prognosis, but it remains unclear whether it is associated with greater functional impairment. Six-minute walk distance (6MWD) is widely used to assess functional capacity in pulmonary hypertension and FIP. OBJECTIVES: To investigate if APH independently contributes to exercise intolerance in FIP, irrespective of the extent of underlying fibrosis...

Sickle cell disease (SCD) patients can have limited exercise capacity and muscle dysfunction characterized by decreased force, atrophy, microvascular abnormalities, fiber distribution changes, and skeletal muscle energetics abnormalities. Growing evidence suggests that in SCD, there is alteration in nitric oxide (NO) availability/signaling and that nitrate/nitrite can serve as a NO reservoir and enhance muscle performance. Here, we examined effects of nitrite on muscle strength, exercise capacity, and on contractile properties of fast-(extensor digitorum longus, EDL) and slow-twitch (soleus) muscles in SCD mice...

Rats exposed to early-life maternal separation (MS) exhibit later alterations in fear conditioning and impairments in fear extinction. As MS creates long-lasting anxiety in the mother, the present study assessed the influence of MS on fear conditioning and extinction in mother rats. It also examined whether estrous cycle effects on extinction, which are robust in nulliparous rats, but abolished in primiparous rats, re-emerge after MS. Following parturition, pups were removed from their mothers for 3 h daily from postpartum day 2-14 (MS), or remained housed with their mothers (standard reared condition, SR)...

BACKGROUND: Cardio-pulmonary-resuscitation (CPR) training starting at the age of 12 years is recommended internationally. Training younger children is not recommended because young children lack the physical ability to perform adequate CPR and discouragement to perform CPR later is apprehended. The aim of this study was to answer the following questions: Are younger children discouraged after CPR training? Is discouragement caused by their lack in physical ability to perform adequate chest compressions on a standard manikin and would the use of manikins with a reduced resistance affect their motivation or performance? METHODS: We investigated the motivation and CPR performance of children aged 8-13 years after CPR training on manikins of different chest stiffness in a prospective, randomized, single-blind, controlled trial...

BACKGROUND: Although some studies have reported significant improvements in physical function and strength after training programs on Liver Transplant (LT) recipients, there is a lack of knowledge on how it affects in static and dynamic balance, being an important part of these participants' tasks development. The aim of the study was to determine the effects of a 6-month multicomponent circuit training program on static and dynamic balance in LT participants. METHODS: 54 participants were randomized at 6 months after LT into 2 groups: exercise group (EXER) and control group (CONTROL), with repeat testing at 6 (baseline) and 12 months after LT...

KEY POINTS: Lifestyle modifications that include the regular performance of exercise are likely important to counteract the negative consequences of obesity on postprandial myofibrillar protein synthetic responses to protein dense food ingestion. We show that the interactive effect of resistance exercise and feeding on the stimulation of myofibrillar protein synthesis rates is diminished with obesity when compared to normal weight adults. The blunted myofibrillar protein synthetic response with resistance exercise in people with obesity may be underpinned by alterations in muscle anabolic signaling phosphorylation (p70S6K and 4E-BP1)...

PURPOSE: Dropout from exercise programs, both in the real world and in research, is a challenge, and more information on dropout-predictors is needed for establishing strategies to increase the likelihood of maintaining participants in a prescribed exercise program. The aim of the present study was to determine the dropout rate and its predictors during a 3-year exercise program in older adults. METHODS: In total, 1514 men and women (age 72.4±1.9 years) were included in the present study...

INTRODUCTION: Low-intensity endurance training performed with blood flow restriction (ET-BFR) can improve muscle strength, cross-sectional area (CSA) and cardiorespiratory capacity. Whether muscle strength and CSA as well as cardiorespiratory capacity (i.e.:V˙O2max) and underlying molecular processes regulating such respective muscle adaptations are comparable to resistance and endurance training is unknown. PURPOSE: To determine the respective chronic (i.e.: 8 weeks) functional, morphological and molecular responses of ET-BFR training compared to conventional, unrestricted resistance training (RT) and endurance training (ET)...

Ingestion of proteins with high leucine content during resistance training (RT) can augment hypertrophy. Some data suggest that a leucine metabolite, β-hydroxy, β-methylbutyrate (HMB), is substantially more anabolically efficacious than leucine. PURPOSE: We aimed to test whether supplementation with HMB versus leucine, added to whey protein, would result in differential muscle hypertrophy and strength gains in young men performing resistance training. METHODS: Twenty-six resistance-trained men (23 ± 2 y) performed 12 wk of RT with 3 phases...

INTRODUCTION: Weakness of foot muscles may contribute to a variety of loading related injuries. Supportive footwear may contribute to intrinsic foot muscle weakness by reducing the muscles' role in locomotion (e.g. absorbing forces and controlling motion). Increased stimulus to the foot muscles can be provided through a variety of mechanisms, including minimalist footwear and directed exercise. PURPOSE: To determine the effect of walking in minimalist footwear or performing foot strengthening exercises on foot muscle size and strength...

Nonalcoholic fatty liver disease (NAFLD) is now the most prevalent liver disease in the world. It involves a spectrum of conditions from hepatic steatosis to nonalcoholic steatohepatitis and liver fibrosis, and is a major cause of cirrhosis and hepatocellular carcinoma. It is defined by presence of steatosis in 5% of hepatocytes or more in the absence of other causes of fatty liver. The metabolic syndrome is the major known risk factor for NAFLD. Dietary contributors such as high fructose intake and coffee consumption appear to increase and decrease the risk of disease respectively, but these links are unclear...

Epigenetic regulation of gene expression differs between fast- and slow-twitch skeletal muscles in adult rats, although the precise mechanisms are still unknown. The present study investigates the differences in responses of RNA polymerase II (Pol II) and histone acetylation during transcriptional activation in the plantaris and soleus muscles of adult rats after acute treadmill running. We targeted the peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) gene to analyze epigenomic changes by chromatin immunoprecipitation...
