... Chronobiological disruptions, including shift work, have been linked to a number of disorders such as fatigue and diabetes. Additionally, there is evidence to support that exercise cannot only counteract fatigue and the onset of diabetes, but also alleviate the other negative symptoms associated with shift work. Therefore, the present study investigated the effects of wheel running and monthly 6-h ...
... The molecular mechanisms of muscle weakness and sarcopenia in postmenopausal women are largely unknown. To determine the effect of a new estrogen receptor, GPR30, in the maintenance of exercise capacity and skeletal muscle function in females, the selective GPR30 agonist, G1 (100 μg/kg/day), or vehicle (V, soybean oil) was administered subcutaneously daily (n = 7 per group) to ovariectomized (OVX) ...
... BACKGROUND: The purple mangosteen (Garcinia mangostana), known as the "queen of fruit," is widely consumed and unique not only because of its outstanding appearance and flavor but also its remarkable and diverse pharmacological effects. The aim of the present study is to evaluate the effect of acute mangosteen supplementation on physical fatigue during exercise. METHODS: A randomized, double-blind ...

... BACKGROUND: Creatine monohydrate (CrM) and nitrate are popular supplements for improving exercise performance; yet have not been investigated in combination. We performed two studies to determine the safety and exercise performance-characteristics of creatine nitrate (CrN) supplementation. METHODS: Study 1 participants (N = 13) ingested 1.5 g CrN (CrN-Low), 3 g CrN (CrN-High), 5 g CrM or a placebo ...
... Acute exercise-induced improvements in cognitive function are accompanied by increased (cerebral) blood flow and increased brain-derived neurotrophic factor (BDNF) levels. Acute cocoa flavanol (CF) intake may improve cognitive function, cerebral blood flow (in humans), and BNDF levels (in animals). This study investigated (i) the effect of CF intake in combination with exercise on cognitive functi ...
... Dopamine/norepinephrine (DA/NE) reuptake inhibitors have been used to manipulate the central mechanisms affecting arousal and motivation during exercise. Eight healthy, physically active males performed 30min fixed-intensity cycling at 50% Wmax followed by 30min of self paced time trial (TT) with each section interspersed with a 30 s maximal sprint at 9, 19 and 29min. The DA/NE re-uptake inhibitor ...

Abstract:
... Exercise training represents a promising approach for managing cognitive impairment in persons with multiple sclerosis (MS). There is preliminary evidence that treadmill walking might be the modality of exercise that exerts the greatest beneficial effects on inhibitory control in fully-ambulatory persons with MS. However, the dose-dependent effects of varying intensities of treadmill walking exerc ...

... This study aimed to assess the effect of two sessions of acute physical exercise at 50% VO2peak performed under hypoxia (equivalent to an altitude of 4500m for 28h) on sleep, mood and reaction time. Forty healthy men were randomized into 4 groups: Normoxia (NG) (n=10); Hypoxia (HG) (n=10); Exercise under Normoxia (ENG) (n=10); and Exercise under Hypoxia (EHG) (n=10). All mood and reaction time ass ...

Abstract:
... Lack of follow up treatment for weight control and maintenance by Mexican women represents a serious problem for the health system. This study assess an intervention to increase adherence in women with overweight and obesity through motivational interviewing combined with brief therapy centered in problem solving cognitive behavioral. A quasi-experimental study was designed, with pre and post trea ...
... Early life stressful events have detrimental effects on the brain and behavior, which are associated with the development of depression. Immune-inflammatory responses have been reported to contribute in the pathophysiology of depression. Many studies have reported on the beneficial effects of exercise against stress. However, underlying mechanisms through which exercise exerts its effects were poo ...

Abstract:
... CicLAvia in Los Angeles, CA is the open streets program that closes streets to motorized vehicles and invites people to walk, run, play or ride their bicycles on these streets, allowing them to experience the city in a new way and get exercise at the same time. Since the events reduce the motorized traffic flow, which is a significant source of air pollution, on the streets, it is reasonable to hy ...
... The adrenal and gonadal stress steroids [i.e., cortisol, testosterone and dehydroepiandrosterone (DHEA)] have gathered considerable attention in the last few decades due to their very broad physiological and psychological actions. Their diurnal patterns have become a particular focus following new data implicating altered diurnal hormone patterns in various endocrine, behavioral and cardiovascular ...
... Several studies have generated numerous terms in the field of exercise training prescription and performance assessment that often do not match the information previously demonstrated by many other works, generating much debate and resulting in an immense pool of scientific results. Several protocols in exercise training prescription and performance assessment have been proposed for these purposes ...
... Panax ginseng C. A. Meyer (ginseng) is an edible and medicinal Chinese herb, which is often used in Asian countries for physical fitness. Ginseng is reported to have a wide range of biological activity and pharmaceutical properties. There were more studies on ginsenosides and polysaccharides, but fewer studies on ginseng oligopeptides (GOP), which are small molecule oligopeptides isolated from gin ...

Abstract:
... Korean Red Ginseng (KRG) is a well-known natural product with anticarcinogenic and antioxidant effects. We evaluated the antifatigue effect of KRG in patients with nonalcoholic fatty liver disease (NAFLD).Eighty patients with NAFLD were prospectively randomized to receive 3 wk of KRG or placebo in addition to counseling on healthy eating and regular exercise. Liver function test, proinflammatory c ...
... Actinidia arguta (Siebold et Zucc.) Planch. ex. Miq. is one of the most recently domesticated fruit species with increasing commercial production worldwide. It is a well-known traditional Chinese medicine and is used to reduce blood glucose and treat atopic dermatitis. In addition, it possesses antioxidant, anticancer, and antiallergic properties. In this study, we investigated the physical antifa ...
... The present study examined the association of anxiety and impulsivity with premature muzzle grayness among young dogs. A sample of 400 dogs, ages 1–4 years was obtained at dog parks, shows, veterinary clinics, and other venues. Each dog was photographed and the degree of muzzle grayness was rated on an ordinal scale ranging from “no gray” to “full gray.” White or pale colored dogs were dropped fro ...
... Discarded electrical and electronic equipment is a growing waste stream becoming more problematic in its management. Unsafe disposal contributes to environmental pollution and threatens human health as well as wasting secondary resources. The recovery of valuable metals from electronic waste can be achieved by bioleaching, a biologically mediated natural chemical process. The bioleaching process m ...
... The aim was to identify benefits of compression garments used for recovery of exercised-induced muscle damage.Computer-based literature research was performed in September 2015 using four online databases: Medline (PubMed), Cochrane, WOS (Web Of Science) and Scopus. The analysis of risk of bias was completed in accordance with the Cochrane Collaboration Guidelines. Mean differences and 95% confide ...

Abstract:
... Research and conservation of wide-ranging wild equids in most cases necessitate capture and handling of individuals. For free-roaming Mongolian khulan (Equus hemionus hemionus), also known as the khulan, capture involves a strenuous, high-speed chase, and physiologic responses have yet to be elucidated. We analyzed sequential arterial blood gas (ABG) samples as a proxy for respiratory and metaboli ...
