PURPOSE: Sweat sodium concentration (SSC) can be determined using different analytical techniques (ATs), which may have implications for athletes and scientists. This study compared the SSC measured with five ATs: ion chromatography (IChr), flame photometry (FP), direct (DISE) and indirect (IISE) ion selective electrode and ion conductivity (IC). METHODS: Seventy sweat samples collected from 14 athletes were analyzed with 5 instruments: the 883 Basic IC Plus (IChr, reference instrument), AAnalyst 200 (FP), Cobas 6000 (IISE), Sweat-Chek (IC) and B-722 Laqua Twin (DISE)...

The consumption of non-nutritive, low or no-calorie sweeteners (LCS) is increasing globally. Previously thought to be physiologically inert, there is a growing body of evidence that LCS not only provide a sweet taste but may also elicit metabolic effects in the gastrointestinal tract. This review provides a brief overview of the chemical and receptor-binding properties and effects on chemosensation of different LCS but focuses on the extent to which LCS stimulates glucose transport, incretin and insulin secretion, and effects on glucose tolerance...

To research the effects of ellagic acid (EA), a low molecular weight polyphenol, on neuron cells and function, and to evaluate whether EA can be safely utilized by humans as a functional food or therapeutic agent, an oxygen-glucose deprivation and reoxygenation (ODG/R) model in primary cultured rat cortical neurons were created in this work. Administration of EA significantly decreased the volume of cerebrum infarction and the neurological deficit scores of the rats; EA treatment also increased the number of Bcl-2-positive cells and the ratio of Bcl-2-positive to Bax-positive neurons in semidarkness zone near brain ischemic focus in the PCI model...

This case series describes and examines the outcomes of a remote culinary coaching program, aimed at improving nutrition through home cooking. Participants (n=4) improved attitudes about the perceived ease of home cooking (p<0.01) and self-efficacy to perform various culinary skills (p=0.02); and also in confidence to continue e-learning culinary skills and consume healthier food. We believe this program might be a viable response to the need for effective and scalable health related culinary interventions...

BACKGROUND: Field-based fitness assessments are time- and cost-efficient. However, no studies to date have reported the predictive value of field-based musculoskeletal fitness assessments in preschoolers. The purpose of this study was to determine the validity of two field assessments to predict peak muscle power in preschool-aged children. METHODS: Four-hundred nineteen 3- to 5-year olds participated (208 girls, 211 boys; mean age: 4.5±0.9 years). Peak power (PP) was evaluated using a modified 10-second Wingate protocol as the criterion standard...

Diet-induced obesity, insulin resistance, impaired glucose tolerance, chronic inflammation and oxidative stress represent the main features of type 2 diabetes mellitus. The present study was conducted to examine the efficacy and mechanisms of shrimp oil on glucose homeostasis in obese rats. Male CD rats fed a high-fat diet (60 kcal% fat) and 20% fructose-drinking water were divided into four groups and treated with the dietary replacement of 0, 10% (SO10), 15% (SO15), or 20% (SO20) of lard with shrimp oil for 10 weeks...

Frequent breaks in prolonged sitting are associated beneficially with glycaemic control. However, the contribution of energy expenditure to these relationships has not been well characterised. In this exploratory analysis, data from three laboratory trials that standardised test meals, cohort characteristics (overweight/obese, sedentary), and break frequency and duration were pooled. Higher energy expenditures of different types of breaks (standing, light- or moderate-intensity walking) were associated with lower post-prandial glucose and insulin responses in a dose-dependent manner...

We examined whether waist circumference (WC) is associated with liver fat in black and white adolescents. Liver fat was measured using a 3T proton magnetic resonance spectroscopy (1H-MRS) in 152 overweight/obese adolescents (94 black and 58 white, BMI >85th percentile, 12-18 yrs) without liver diseases or diabetes. WC was measured at the last rib. Total and visceral adipose tissue (VAT) were measured by DXA and MRI, respectively. The proportion of fatty liver (defined as liver fat >5.0% by 1H-MRS) was lower (P<0...

We evaluated the influence of K(+) channels (i.e., Ca(2+)-activated K(+) (KCa), ATP-sensitive K(+) (KATP), and voltage-gated K(+) (KV) channels) and key enzymes (nitric oxide synthase (NOS) and cyclooxygenase (COX)) on nicotine-induced cutaneous vasodilation and sweating. Using intradermal microdialysis, we evaluated forearm cutaneous vascular conductance (CVC) and sweat rate in 2 separate protocols. In protocol 1 (n = 10), 4 separate sites were infused with (i) lactated Ringer (Control), (ii) 50 mmol·L(-1) tetraethylammonium (KCa channel blocker), (iii) 5 mmol·L(-1) glybenclamide (KATP channel blocker), and (iv) 10 mmol·L(-1) 4-aminopyridine (KV channel blocker)...

Due to gastrointestinal tract adaptability, the study aimed to determine the impact of gut-training protocol over 2 weeks on gastrointestinal status, blood glucose availability, fuel kinetics, and running performance. Endurance runners (n = 25) performed a gut-challenge trial (GC1), consisting of 2 h running exercise at 60% V̇O2max whilst consuming gel-discs containing 30 g carbohydrates (2:1 glucose/fructose, 10% w/v) every 20 min and a 1 h distance test. Participants were then randomly assigned to a carbohydrate gel-disc (CHO-S), carbohydrate food (CHO-F), or placebo (PLA) gut-training group for 2 weeks of repetitive gut-challenge intervention...

There is increasing awareness of the detrimental health impact of frailty on older adults and of the high prevalence of malnutrition in this segment of the population. Experts in these 2 arenas need to be cognizant of the overlap in constructs, diagnosis, and treatment of frailty and malnutrition. There is a lack of consensus regarding the definition of malnutrition and how it should be assessed. While there is consensus on the definition of frailty, there is no agreement on how it should be measured. Separate assessment tools exist for both malnutrition and frailty; however, there is intersection between concepts and measures...

This research investigated associations between home environment chaos, fat intake, and morning serum cortisol level in 44 parents of preschool-age children. Chaos was measured using the Confusion, Hubbub, and Order Scale, and fat intake was quantified using the Block fat screener. Linear regression analyses demonstrated that chaos and cortisol were both associated with fat intake (β^ = 0.53, p= 0.001;β^ = 0.03, p= 0.0002), and there was a non-significant association between chaos and cortisol.

Oxidative stress has a crucial role in the progression of diabetes and its complications. Soluble fibre-rich fenugreek seeds (Trigonella foenum-graecum L.) are understood to have a beneficial effect in the management of diabetes. Previously, we have shown that the amelioration of diabetic hyperglycemia and related metabolic abnormalities was potentiated by onion (Allium cepa L.) in experimental rats. The present study evaluated the additive beneficial effect of dietary fenugreek seeds (10%) and onion (3%) on oxidative stress in diabetic rats...

Whole body active warm ups (AWU) and inspiratory muscle warm up (IMW) prior to exercise improves performance on some endurance exercise tasks. This study investigated the effects of AWU with and without IMW upon 2.4 km running time-trial performance while carrying a 25 kg backpack, a common task and backpack load in physically demanding occupations. Participants (n = 9) performed five 2.4 km running time-trials with a 25 kg thoracic load preceded in random order by 1) IMW comprising 2 x 30 inspiratory efforts against a pressure-threshold load of 40 % maximal inspiratory pressure (PImax), 2) 10 min unloaded running (AWU) at lactate turnpoint (10...

We hypothesized a sweet potato intervention would prevent high fat diet-induced aortic stiffness, which would be associated with decreased arterial oxidative stress and increased mitochondrial uncoupling. Young (8-week old) C57BL/6J mice were randomly divided into 4 groups: low fat (LF, 10% fat), high fat (HF, 60% fat), low fat sweet potato (LFSP, 10% fat containing 260.3 ug/kcal SP), or high fat sweet potato diet (HFSP, 60% fat containing 260.3 ug/kcal SP) for 16 weeks. Compared to LF and LFSP, HF and HFSP fed mice had increased body mass and percent fat mass with lower percent lean mass (all, P<0...

Four elite rowers completed a twelve-day altitude training camp living at 1800m, and training at 1800m and 915m, to assess changes in resting metabolic rate (RMR). RMR and body composition were assessed PRE and POST-camp. Downward trends in RMR and body composition were observed post-altitude: absolute RMR (percent change: -5.2%), relative RMR (-4.6%), body mass (-1.2%), and fat mass (-4.1%), likely related to the hypoxic stimulus and an imbalance between training load and energy intake.

This study examined the degree to which various mechanical, biochemical and dietary factors are related to non-weight bearing bone properties in 172 healthy peri-pubertal children (11.7±2.0 years). Dominant radial speed of sound (rSOS) was measured by transaxial quantitative ultrasound at distal radius. Potential modulating factors included somatic maturity offset (years from age of peak height velocity), grip strength, forearm lean cross-sectional area (CSA), physical activity, nutritional intake and amino-terminal cross-linking propeptide (NTx), reflecting bone resorption...

The purpose of this study was to evaluate the accuracy of 2 newly developed physical activity questionnaires: the Canadian Society for Exercise Physiology (CSEP) Physical Activity and Sedentary Behaviour Questionnaire (PASB-Q) and a newly modified Leisure-Time Physical Activity Questionnaire (mLTPA-Q). These questionnaires were compared with objective measurements of physical activity and fitness (accelerometry and physiological assessments) in 35 adults, before and after a week of daily living activity. Objectively measured moderate- to vigorous-intensity aerobic physical activity (MVPA) was moderately correlated with the PASB-Q's physical activity vital sign (PAVS) (r = 0...

Vascular endothelial dysfunction (VED) plays an important role in initiation of cardiovascular diseases. Roselle which enriched with antioxidants demonstrates high potential in alleviating hypertension. This study was undertaken to investigate effects of roselle supplementation on VED and remodelling in a rodent model with prolonged nicotine administration. Male Sprague-Dawley rats (n=6 per group) were administered with 0.6 mg/kg nicotine for 28 days to induce VED. The rats were given either roselle (100 mg/kg) or normal saline 30 minutes prior to nicotine injection daily...

Blueberries are rich in flavonoids, which possess antioxidant and anti-inflammatory properties. High flavonoid intakes attenuate age-related cognitive decline, but data from human intervention studies are sparse. We investigated whether 12 weeks of blueberry concentrate supplementation improved brain perfusion, task-related activation and cognitive function in healthy older adults. Participants were randomised to consume either 30 ml blueberry concentrate providing 387 mg anthocyanidins (5 female, 7 male; age 67...
