The acute influence of amateur boxing on dynamic cerebral autoregulation and cerebrovascular reactivity to carbon dioxide.

Purpose: The purpose of this study was to investigate the acute effect of head impacts, sustained over the course of three rounds of amateur boxing, on indices of cerebrovascular function.

Methods: Eighteen university amateur boxers (six female) completed three experimental trials in a randomised order; (1) three rounds of boxing (BOX), (2) an equivalent bout of pad boxing (where no blows to the head were sustained; PAD), and (3) a time-matched seated control trial (CON). Indices of cerebrovascular function were determined immediately before and 45 min after each trial.

Resistance exercise acutely elevates dynamic cerebral autoregulation gain.

Dynamic cerebral autoregulation (dCA) describes the regulation of cerebral blood flow (CBF) in response to fluctuations in systemic blood pressure (BP). Heavy resistance exercise is known to induce large transient elevations in BP, which are translated into perturbations of CBF, and may alter dCA in the immediate aftermath. This study aimed to better quantify the time course of any acute alterations in dCA after resistance exercise.

Cerebral blood flow regulation is not acutely altered after a typical number of headers in women footballers.

Background: The repeated act of heading has been implicated in the link between football participation and risk of neurodegenerative disease, and acutely alters cerebrovascular outcomes in men. This study assessed whether exposure to a realistic number of headers acutely influences indices of cerebral blood flow regulation in female footballers.

Methods: Nineteen female players completed a heading trial and seated control trial on two separate days.

[Study of the metabolic syndrome and physical activity in a population from Marrakesh, in Morocco].

Introduction: the aim of this study was to correlate the metabolic syndrome with the level of the physical activity in a population from Marrakech, Morocco.

Methods: the study was conducted at Ibn Zohr Regional Hospital in Marrakech. The body mass index (BMI) was calculated to assess the degree of obesity of each subject.

Epidemiological profile and clinical characteristics of metabolic syndrome in Marrakesh, Morocco.

Introduction: the purpose of this study was to bring out some epidemiological and clinical characteristics of metabolic syndrome.

Methods: a total of 300 subjects willingly participated in the present study which was conducted at Ibn Zohr regional hospital in Marrakesh. We were interested in socio-demographic variables, body mass index (BMI) which assesses the degree of obesity of each subject.
