BACKGROUND: Aerobic exercise training is a promising complementary treatment option in migraine and can reduce migraine days and improve retinal microvascular function. Our aim was to elucidate whether different aerobic exercise programs at high vs. moderate intensities distinctly affect migraine days as primary outcome and retinal vessel parameters as a secondary. METHODS: In this randomized controlled trial, migraine days were recorded by a validated migraine diary in 45 migraineurs of which 36 (female: 28; age: 36 (SD:10)/ BMI: 23...

The single leg supine bridge (SLB) is a commonly employed strengthening exercise and is used as a clinical test for hamstring function in sports, however, little is known about the patterns of muscle activation in this task. To explore these activation patterns, nine healthy, recreationally active males underwent functional magnetic resonance imaging (fMRI) of their thighs at rest and immediately after 5 sets of 10 repetitions of the SLB exercise. Exercise-induced increases in the transverse (T2) relaxation time of the biceps femoris long and short heads, semitendinosus and semimembranosus, were determined via signal intensity changes in pre- and post-exercise images and used as an index of muscle activation...

Postoperative atrial fibrillation (POAF) is associated with increased stroke risk and mortality post-discharge. POAF is often considered transient; however, recurrence is likely under-recognized as symptoms are an unreliable guide. Surveillance post-discharge may identify asymptomatic POAF recurrences in patients discharged in sinus rhythm. Therefore, we performed a systematic review and meta-analysis of studies investigating POAF recurrence post-discharge, in patients with new-onset POAF following cardiac surgery who reverted to sinus rhythm prior to discharge...

Obesity, sedentary lifestyle and aging are associated with mitochondrial dysfunction and impaired insulin sensitivity. Acute exercise increases insulin sensitivity in skeletal muscle; however, whether mitochondria are involved in these processes remains unclear. The aim of this study was to investigate the effects of insulin stimulation at rest and after acute exercise on skeletal muscle mitochondrial respiratory function (JO2) and hydrogen peroxide emission (JH2O2), and the associations with insulin sensitivity in obese, sedentary men...

BACKGROUND: Although researchers have recommended exercise training and psychosocial intervention to manage chronic pain, an effective intervention for Japanese community-dwelling older adults with chronic pain has not been established. This randomized controlled trial examined whether exercise training combined with psychosocial intervention more effectively improves pain, psychological status and physical activity than does exercise training alone in this population. METHODS: We randomized 128 older adults with chronic pain to either an intervention group (n = 64) involving exercise training combined with psychosocial intervention, or a control group (n = 64) involving only exercise training...

High-intensity exercise increases the concentration of circulating lactate. Cortical uptake of blood borne lactate increases during and following exercise, however the potential relationship with changes in the concentration of neurometabolites remains unclear. While changes in neurometabolite concentration have previously been demonstrated in primary visual cortex following exercise, it remains unknown whether these changes extend to regions such as sensorimotor cortex (SM) or executive regions such as dorsolateral prefrontal cortex (DLPFC)...

The present study aimed to identify whether or not the release of interleukin (IL)-6 and soluble (s) IL-6 receptor (R) is associated with fatiguing behaviour and changes in cortical activity during self-paced exercise. Relationships between the IL-6 and its soluble receptors, total work, reductions in power output, and changes in slow, alpha (α) and fast, beta (β) brain waves during self-paced exercise were evaluated. Different intensities and environments were used to manipulate the release of IL-6, whereby seven active males cycled for 60 min in heat stress (HS) or thermoneutral (TN) environments at a clamped rating of perceived exertion (RPE) equating to low intensity (RPE = 12) or high intensity (RPE = 16)...

Previously it was demonstrated that mineralization and alkalization properties of mineral water are important factors influencing acid-base balance and hydration in athletes. The purpose of this study was to investigate the effects of drinking different types of water on urine pH, specific urine gravity, and post-exercise lactate utilization in response to strenuous exercise. Thirty-six male soccer players were divided into three intervention groups, consuming around 4.0 l/day of different types of water for 7 days: HM (n=12; highly mineralized water), LM (n=12; low mineralized water), and CON (n=12; table water)...

In addition to different injuries, infections are the most common reason for giving up training altogether or reducing its volume and intensity, as well as a lack of opportunities to participate in sports competitions. Nowadays, a slow but constant re-emergence of pertussis, especially among teenagers and young adults, including athletes, can be observed. This paper describes an outbreak of pertussis among professional Polish shooters, focusing on the transmission of Bordetella pertussis infection between members of the national team, its influence on performance capacity and adverse event analysis...

Our study in the Journal of Sports Sciences was originally designed to test whether the bar-velocity is a precise indicator of the power training intensity (i.e., optimum loads) in different exercises commonly included in athletes' training programs. Furthermore, we presented secondary findings, related to the actual results obtained in our assessments. As a cross-sectional study with clear objectives, we focused on discussing issues and applications pertaining to neuromuscular training interventions, such as: (1) describing the advantages of using bar-velocities to control the power training intensity, (2) defining a range of loads capable of maximizing the power production in certain ballistic and traditional exercises, and (3) revealing the differences between these exercises and the respective implications for training...

The practice of sport and medium-high intensity exercise increases the needs of energy and nutrients. Proper nutrition is very important for reaching the maximum performance, reducing the risk of injury, and ensuring the best recovery. It must also ensure the achievement of optimum nutritional status and prevent health problems at the present and in the future time. Eggs are a very nutritious food that can help athletes to achieve a correct diet. It contains proteins of high quality and bioavailability, a profile of fatty acids very favorable from the cardiovascular point of view, and vitamins and minerals involved in energy and protein metabolism, in defense against oxidative stress and inflammation, in cell growth and tissue repair...

Obesity is one of the five leading global risks for mortality, accounting for 5% of deaths worldwide. Workplace health promotion programs have the potential to deliver population-level interventions combining physical activity and exercise. However, there is no recent critical review of trials on long-term effectiveness of multicomponent lifestyle interventions in the workplace targeting obesity. Good quality evidence is needed to develop optimal strategies to tackle adult obesity. 1035 studies were retrieved by literature search in MEDLINE, Embase, PSYCH INFO and Cochrane library from 2005 to September 2016...

Response to sudden epidemic infectious disease emergencies can demand intensive and specialized training, as demonstrated in 2014 when Ebola virus disease (EVD) rapidly spread throughout West Africa. The medical community quickly became overwhelmed because of limited staff, supplies, and Ebola treatment units (ETUs). Because a mechanism to rapidly increase trained healthcare workers was needed, the US Centers for Disease Control and Prevention developed and implemented an introductory EVD safety training course to prepare US healthcare workers to work in West Africa ETUs...

Nitric oxide (NO)-dependent sweating is diminished during high but not moderate intensity exercise. We evaluated whether this impairment stems from increased oxidative stress during high intensity exercise. On two separate days, 11 young (24 ± 4 years) males cycled in the heat (35°C) at a moderate (500 W; 52 ± 6%VO2peak ) or high (700 W; 71 ± 5%VO2peak ) rate of metabolic heat production. Each session included two 30-min exercise bouts separated by a 20-min recovery. Local sweat rate was monitored at four forearm skin sites continuously perfused via intradermal microdialysis with: (1) lactated Ringer's solution (Control), (2) 10 mm ascorbate (Ascorbate; non-selective antioxidant), (3) 10 mm N(G) -nitro-L -arginine methyl ester (L-NAME; NO synthase inhibitor), or (4) 10 mm Ascorbate + 10 mm L-NAME (Ascorbate + L-NAME)...
