Whey protein is a commonly ingested nutritional supplement amongst athletes and regular exercisers; however, its role in post-exercise rehydration remains unclear. Eight healthy male and female participants completed two experimental trials involving the ingestion of 35 g of whey protein (WP) or maltodextrin (MD) at the onset of a rehydration period, followed by ingestion of water to a volume equivalent to 150% of the amount of body mass lost during exercise in the heat. The gastric emptying rates of the solutions were measured using 13 C breath tests...

INTRODUCTION: Post-cessation weight gain contributes to smoking relapse, especially for women. Furthermore, excess weight in the form of android or visceral fat is associated with metabolic health problems. For this study, a secondary analysis was conducted in 2015 to determine whether quitting status, achieved through a 14 week supervised exercise-aided nicotine replacement therapy (NRT) cessation program [Getting Physical on Cigarette Trial-2009 to 2013; Prapavessis, et al., 2016], affects anthropometric and body composition parameters in female smokers (N = 413, M age = 42...

Angiotensin II (Ang II) synthesized in response to body fluid loss caused by actions such as sweating and breathing is today considered as one of the essential factors for promoting hippocamal neurogenesis. Because heat-stimuli, along with exercise, increases systemic levels of Ang II, the effects of short-term heat exposure on hippocampal neurogenesis were examined in adult male rats. When rats were exposed daily to a 1 h heat treatment (36.0 ± 0.1°C) during a 7 d experimental period, the number of doublecortin-immunoreactive newborn cells in the hippocampal dentate gyrus was increased approximately 1...

The Supportive Care Nursing Clinical Protocol (SCNCP) was developed to guide holistic nursing care for seriously ill hospitalized patients. The SCNCP uses national guidelines and evidence-based interventions as its foundation. Seriously ill patients may require palliative care, which is synonymous with supportive care. Acute care nurses may not be proficient in providing holistic supportive care for patients with life-limiting illness. At a 670-bed public acute care hospital, palliative care consultation requires a physician order and palliation may arrive late in an illness...

AIMS AND OBJECTIVE: To explore patients' experiences of acute dyspnea, physical functioning, and perspectives on course of illness prior to admission to the emergency department. BACKGROUND: Many emergency admissions are considered unnecessary and avoidable. In this perspective, it seems relevant to gain insight into the patients' perspective on acute dyspnea and the need for emergency admission. However, only few studies have investigated reasons for emergency admission from a patient perspective...

Athletes regularly endure large increases in ventilation and accompanying perceptions of breathlessness. Whilst breathing perceptions often correlate poorly with objective measures of lung function in both health and clinical populations, we have previously demonstrated closer matching between subjective breathlessness and changes in ventilation in endurance athletes, suggesting that athletes may be more accurate during respiratory interoception. To better understand the link between exercise and breathlessness, we sought to identify the mechanisms by which the brain processing of respiratory perception might be optimised in athletes...

The single breath hold maneuver for measuring lung diffusing capacity for carbon monoxide (DLCO) and nitric oxide (DLNO) incorporates multiple sources of variability. This study examined how changes in intrathoracic pressure, inhalation time, and breath hold time affect DLCO, DLNO, alveolar-capillary membrane conductance (DmCO) and pulmonary capillary blood volume (Vc) at rest and during submaximal exercise. Thirteen healthy subjects (mean ± SD; age = 26 ± 3y) performed duplicate tests at rest and during submaximal exercise...

PURPOSE: Dyspnea has been reported to be a main contributor to exercise avoidance in asthma. While traditional markers of ventilation do not explain the heightened dyspnea during exercise in asthmatics, this study proposed that exertional dyspnea in asthma was due to high operating lung volumes, which may be improved with a short-acting beta2-agonist. METHODS: On two separate days, sixteen asthmatics and 16 controls completed a lung function test and incremental exercise tests to exhaustion...

Cardiac patients often experience nocturnal and daytime oscillatory breathing (OB). OB noted at rest sometimes becomes unclear or even disappears during exercise. We evaluated the physiological significance of OB by comparing the clinical characteristics of cardiac patients who manifested OB only at rest (group A), only during exercise (group B), and both at rest and during exercise (group C).Among 3,432 cardiac patients who underwent cardiopulmonary exercise testing (CPX), 114, 94, and 65 patients were identified as group A, B, and C, respectively...

Purpose: Hypoxemia is associated with more severe lung disease and worse outcomes. In some patients with chronic obstructive lung diseases who desaturate on exertion, supplemental oxygen improves exercise capacity. The clinical significance of this exercise response to oxygen supplementation is not known. Patients and methods: We identified chronic obstructive lung disease patients at our center who underwent a 6-minute walking test (6MWT) for ambulatory oxygen assessment and who desaturated breathing air and therefore had an additional walk test on supplemental oxygen, between August 2006 and June 2016...
