Effects of Chronic Exercise on Endothelial Progenitor Cells and Microparticles in Professional Runners

Arq. bras. cardiol; 108 (3), 2017
Abstract Background: The effects of chronic exposure to exercise training on vascular biomarkers have been poorly explored. Objective: Our study aimed to compare the amounts of endothelial progenitor cells (EPCs), and endothelial (EMP) and platelet (PMP) microparticles between professional runners and ...

Effects of ceramic garments on 10-km running performance

Motriz (Online); 23 (3), 2017
Aims: The use of electromagnetic waves by phototherapy to skeletal muscle presents potential ergogenic effects. The aim of this study was to analyze the effect of using bioceramic clothes on performance, heart rate (HR) and rating of perceived exertion (RPE) during a 10 km race. Our hypothesis is that th...

Post-analysis methods for lactate threshold depend on training intensity and aerobic capacity in runners. An experimental laboratory study

Säo Paulo med. j; 134 (3), 2016
ABSTRACT CONTEXT AND OBJECTIVE: This study aimed to evaluate different mathematical post-analysis methods of determining lactate threshold in highly and lowly trained endurance runners. DESIGN AND SETTING: Experimental laboratory study, in a tertiary-level public university hospital. METHOD: Twenty...

Relationships between static foot alignment and dynamic plantar loads in runners with acute and chronic stages of plantar fasciitis: a cross-sectional study

BACKGROUND: The risk factors for the development of plantar fasciitis (PF) have been associated with the medial longitudinal arch (MLA), rearfoot alignment and calcaneal overload. However, the relationships between the biomechanical variables have yet to be determined. OBJECTIVE: The goal of this study...

Evaluation of energy expenditure in forward and backward movements performed by soccer referees

Braz. j. med. biol. res; 49 (5), 2016
The aim of this study was to measure the energy expenditure for locomotor activities usually performed by soccer referees during a match (walking, jogging, and running) under laboratory conditions, and to compare forward with backward movements. The sample was composed by 10 male soccer referees, age 29�...

Male and female runners demonstrate different sagittal plane mechanics as a function of static hamstring flexibility

ABSTRACTBackground:Injuries to runners are common. However, there are many potential contributing factors to injury. While lack of flexibility alone is commonly related to injury, there are clear differences in hamstring flexibility between males and females.Objective: To compare the effect of static ham...

Marcadores hematológicos de corredores amadores do município de Vitória/ES

Introdução: O sistema imunológico apresenta estreita relação com o exercício físico. Todavia, poucos estudos verificaram o perfil imunológico de corredores amadores. Objetivo: Descrever o perfil de marcadores imunológicos de corredores amadores do município de Vitória/ES no ...

Comparação ecodopplercardiográfica da dinâmica valvar entre atletas ciclistas, corredores e futebolistas e indivíduos sedentários

Arq. bras. cardiol; 61 (3), 1993
PURPOSE--To compare the patterns of valvar dynamics expressed by the mitral prolapse and regurgitation across the valves, between competitive athletes players of distinctive sport modalities, and between these and sedentary control subjects. METHODS--Pulsed and continuous wave non-colour Doppler echocard...

Lipoproteínas e lipídios séricos após a competiçäo de Triatlon em mulheres treinadas
Serum lipids and lipoproteins after a competitive Triathlon in trained women

Rev. bras. ciênc. mov; 6 (2), 1992
O propósito desse estudo foi examinar o efeito imediato e retardado dos lipídios séricos e lipoproteicos em mulheres que competem em triatlon. Oito mulheres triatletas treinadas foram examinadas. Todas fizeram parte de uma competiçao de triatlon que consistiu em 1,9 Km de nataçao, 90 Km de ciclismo ...
