Aims: This systematic review aims to evaluate and summarize findings from published meta-analyses on the effects of regular exercise in patients with peripheral arterial disease (PAD). The review will assess the impact of exercise on functional parameters, health-related quality of life, haemodynamic parameters, physical activity levels, adverse e...

Alzheimer's disease (AD) is determined by various pathophysiological mechanisms starting 10 to 25 years before the onset of clinical symptoms. As multiple functionally interconnected molecular/cellular pathways appear disrupted in AD, the exploitation of high-throughput unbiased omics sciences is critical to elucidating the precise pathogenesis of...

In addition to the bibliometric analysis, we decided to compile resources to start reading about BFR.

Blood flow restriction (BFR) training was discovered in 1966 by Yoshiaki Sato, who called it Kaatsu. Over the years, BFR has gained popularity both in the scientific community and the practical field. The prolific literature in the field accumulated over these years may overwhelm a professional or scientist willing to explore BFR. In this study, we...

Neuromuscular electrical stimulation (NMES) in combination with blood flow restriction (BFR) enhances muscle hypertrophy and force-generating capacity. The present study aimed to investigate the acute effects of BFR and NMES, both in isolation and in combination, on muscle thickness (MT) and fatigue in the lower body of 20 young healthy subjects. D...

Peripheral arterial disease (PAD) is a prevalent cardiovascular disease. The main hallmarks of this condition are atherosclerosis and myopathy in the lower limbs, with progressive deterioration of the functional capacity and quality of life of affected individuals. There is evidence supporting physical exercise as an effective alternative for the t...

Background: Traditional aerobic training and muscle resistance ('strength') training have been shown to be effective for improving functional and health-related quality of life (HRQoL) outcomes in peripheral arterial disease (PAD). However, the transfer of the current resistance exercise modes proposed to other activities of daily living (ADLs) is...

Atrial fibrillation is the arrhythmia with the highest prevalence world-wide. In fact, scientific literature seems to show a high prevalence of atrial fibrillation in endurance athletes too. However, currently the relationship between atrial fibrillation and aerobic exercise is controversial. On the one hand, aerobic exercise could be defined as a...

Hamstring muscle injuries are one of most frequent injuries in team sports. Whole-body vibration (WBV) has an important effect on flexibility that could prevent shortening of the hamstrings. To investigate both acute and residual effect of a single bout of WBV on hamstring flexibility in a group of university athletes from team sports 70 athletes (...

La fibrilación auricular (FA) es la arritmia cardíaca más frecuente y a pesar de los importantes avances en el tratamiento de pacientes con FA, esta arritmia sigue siendo una de las principales causas de morbilidad y mortalidad. Aunque los beneficios del ejercicio físico para la salud están bien establecidos en otras enfermedades cardiovasculares,...

Objective: The most used search engine for scientific literature, PubMed, provides tools to filter results by several fields. When searching for reports on clinical trials, sample size can be among the most important factors to consider. However, PubMed does not currently provide any means of filtering search results by sample size. Such a filteri...

The combination of low-load resistance training [or more recently, neuromuscular electrical stimulation (NMES)] with a moderate local blood flow restriction (BFR) is becoming a widespread training and rehabilitation method. Scientific data indicate the overall safety of BFR, at least in healthy young people. However, it has been associated with sid...

The purpose of this study was to determine the adaptive response of ratings of perceived exertion (RPE) and pain over six consecutive training sessions. Thirty subjects were assigned to either a blood flow restricted training group (BFRT) or a high intensity group (HIT). BFRT group performed four sets (30+15+15+15, respectively) of unilateral leg e...

Cortical/cerebral visual impairment (CVI) is clinically defined as significant visual dysfunction caused by injury to visual pathways and structures occurring during early perinatal development. Depending on the location and extent of damage, children with CVI often present with a myriad of visual deficits including decreased visual acuity and impa...

El objetivo del presente estudio fue analizar los efectos agudos de las vibraciones de cuerpo completo (VCC) sobre el equilibrio y la movilidad en niños con parálisis cerebral, y comparar los efectos producidos por el estímulo vibratorio vertical y oscilante sobre las variables mencionadas. Se utilizó un diseño cruzado aleatorio en el que participa...

Introduction: Exercise and muscle contraction provide a powerful stimulus for vascular remodeling. Endothelial cells aresubjected to the shear stress resulting from blood flow and are able to convert mechanical stimuli into intracellular signals that affect cellular functions. Whole body vibration (WBV) has been shown to produce increases in blood...

Objective The aim of this study was to analyze the effects of a rehabilitation program with whole body vibration on static and functional balance in chronic stroke patients.

The American College of Sports Medicime recommends lifting weights over 70% 1 RM to induce hypertrophy trough resistance training. High intensity training induces maximal neural and mechanical activation of musculature. However, low intensity resistance training (20-50% 1 RM), when combined with blood flow restriction of the proximal part of the ex...
