There is little argument that physical activity is beneficial for one’s health. Indeed, increasing the amount of physical activity is associated with extensive health improvement, mostly in coronary artery disease, hypertension, stroke, insulin sensitivity, osteoporosis, and depression [1–4]. As such, the United States Department of Health and Human Services recommends ‘‘physical activity most ...

Background. Increasingly, women are training and competing in mixed martial arts (MMA). Women are, however, hugely underrepresented in the research literature. Objectives. The purpose of this brief report was to assess concussion knowledge, mental health and attention-related errors among female MMA competitors and factors that might affect data quality when doing a study during a competition....

It is time to stop using the term concussion as it has no clear definition and no pathological meaning. This confusion is increasingly problematic as the management of 'concussed' individuals is a pressing concern. Historically, it has been used to describe patients briefly disabled following a head injury, with the assumption that this was due to a transient disorder of brain function without ...

Concussion is one of the commonest forms of neurological injury seen throughout the world. Although common in sport, this condition has parallels in the types of injury suffered in motor vehicle crashes, falls, and other forms of brain trauma. Despite the fact that the eVects of brain injuries have been recognised for at least 3000 years and the clinical state of concussion initially described ...

The decision to advise an athlete to retire from sports following sports-related concussion (SRC) remains a persistent challenge for physicians. In the absence of strong empirical evidence to support recommendations, clinical decision making must be individualized and should involve a multidisciplinary team of experts in concussion and traumatic brain injury. Although previous authors have advo...

In order to assess whether cerebral anomalies may be observed in the absence of clinical symptoms, the current study compared the effects of concussions on attentional capacities (reaction times, accuracy) and Event-Related Potentials (ERPs) in concussed athletes with (n = 10) or without (n = 10) symptoms as well as in athletes who never had a concussion (n = 10). The P300 response was recorded...

This study examined how MTBI concomitants such as pain variables, depression, and anxiety were related to attentional functioning at different stages of recovery. Participants having sustained a MTBI who were in the earlier phase of recovery showed, compared to controls, slower reaction times and larger intra-individual variability on a Computerized Pictorial Stroop Task (CPST). They also repor...

Concussions and mild traumatic brain injuries have become more widely recognized and understood during the past 5 to 10 years. Earlier and more active evaluation and management of this brain injury is necessary to reduce risk to the developing child and adolescent. Pediatricians play a central role in the evaluation and management of concussions and should develop a working understanding of the...

INTRODUCTION Sport concussion represents the majority of brain injuries occurring in the United States with 1.6–3.8 million cases annually. Understanding the biomechanical properties of this injury will support the development of better diagnostics and preventative techniques. METHODS We monitored all football related head impacts in 78 high school athletes (mean age = 16.7 yr) from 2005 to 2...
