Previous studies have shown that fibromyalgia syndrome (FMS) is associated with low level of physical activity and exercise, which may lead to an increased risk of osteoporosis. However, studies of bone mineral density (BMD) in fibromyalgia have shown conflicting results. Thus, we conducted a systematic review and meta-analysis to better characterize the association between FMS and BMD. A comprehensive search of the databases MEDLINE and EMBASE was performed from inception through May 2016. The inclusion criterion was the observational studies' assessment of the association between fibromyalgia and bone mineral density in adult subjects...

BACKGROUND: While exercise testing is increasingly used as a prognostic indicator in cystic fibrosis (CF), it is reported to be underused in UK CF centres, particularly in children. Here, we evaluated the cardiopulmonary exercise testing (CPET) results in children and young people with CF at CF annual review and its possible clinical value. METHOD: An observational study comparing CPET results using a cycle ergometer ramp test (peak oxygen uptake (Vo2peak)) and pulmonary function (forced expiratory volume in 1 s (FEV1)) was performed with body mass index (BMI) used as a disease severity marker...

INTRODUCTION: During maximal, sustained contractions, persons with multiple sclerosis (PwMS) show higher motor fatigability in comparison with healthy persons. It is not known if motor fatigability is also different between PwMS and healthy persons during low-intensity exercises. Thus, the aim of this study was to determine the difference in hand grip fatigability between healthy persons and PwMS for both hands during low-intensity hand grip exercises. METHODS: 19 PwMS and 19 healthy controls performed 18min of hand grip exercises at a maximum of 25% of the maximal voluntary strength, with an electronic hand dynamometer...

BACKGROUND: The treadmill exercise test (TET) is one of the most common noninvasive diagnosis approaches for ischemic heart diseases, but potential reduction of TET accuracy among Chinese female patients was ignored by most studies, especially in perimenopause women. Hence, we aim to perform a systematic review and meta-analysis evaluating the TET diagnostic accuracy for Chinese women compared with coronary angiography (CAG). METHODS: PubMed, MEDLINE, EMBASE, CNKI and WANFANG (1990 to 2015) were performed to identify studies assessing the diagnostic accuracy of TET versus CAG...

Iñigo Mujika
Training quantification is basic to evaluate an endurance athlete's responses to the training loads, ensure adequate stress/recovery balance and determine the relationship between training and performance. Quantifying both external and internal workload is important, because the external workload does not measure the biological stress imposed by the exercise sessions. Generally used quantification methods include retrospective questionnaires, diaries, direct observation and physiological monitoring, often based on the measurement of oxygen uptake, heart rate and blood lactate concentration...

PURPOSE: Typically, accessing the asymptote (Critical Power; CP) and curvature constant (W') parameters of the hyperbolic power-duration relationship requires multiple constant-power, exhaustive exercise trials, spread over several visits. However, more recently single-visit protocols and personal power meters have been used. We investigated the practicality of using a two-trial, single-visit protocol in providing reliable CP & W' estimates. METHODS: 8 trained cyclists underwent 3- and 12-min maximal exercise trials in a single session to derive (2-trial) CP & W' estimates...

Working memory lies at the core of cognitive function and plays a crucial role in children's learning, reasoning, problem solving, and intellectual activity. Behavioral findings have suggested that acute aerobic exercise improves children's working memory; however, there is still very little knowledge about whether a single session of aerobic exercise can alter working memory's brain activation patterns, as assessed by functional magnetic resonance imaging (fMRI). Therefore, we investigated the effect of acute moderate-intensity aerobic exercise on working memory and its brain activation patterns in preadolescent children, and further explored the neural basis of acute aerobic exercise on working memory in these children...

BACKGROUND: Peak oxygen uptake (VO2peak) established during progressive cardiopulmonary exercise testing (CPET) is the "gold-standard" for cardiorespiratory fitness. However, CPET measurements may be limited in patients with aneurysmal subarachnoid hemorrhage (a-SAH) by disease-related complaints, such as cardiovascular health-risks or anxiety. Furthermore, CPET with gas-exchange analyses require specialized knowledge and infrastructure with limited availability in most rehabilitation facilities...
