Participation in organized sports is promoted as a means of increasing physical activity levels and reducing chronic disease risk in adults. Hard martial arts practice (i.e. using body contact techniques), has gained in popularity over time. This review explores the evidence for health benefits of "hard" martial arts practice within the adult population. A systematic electronic database search was conducted, and quality assessments applied the Effective Public Health Practice Project tool. Twenty-eight studies met the inclusion criteria, examining balance, cognitive function, muscular skeletal status, psychological, cardiovascular fitness, and metabolic effects...

Carotid artery dissection is a significant cause of stroke in young patients. It may be asymptomatic and go undiagnosed, or minimal transient manifestations may follow, commanding a higher index of suspicion than ordinarily exists to avoid misdiagnosis. Reported herein is a 27-year-old man who suffered extracranial internal carotid artery dissection while practicing a Brazilian Jiu-Jitsu submission maneuver. The patient's condition suddenly deteriorated one week later due to distal embolization and stroke. Despite endovascular treatment, with stenting of the cervical carotid artery, neurologic deficits remained...

The aim of this paper is to propose and evaluate the novel method of template generation, matching, comparing and visualization applied to motion capture (kinematic) analysis. To evaluate our approach, we have used motion capture recordings (MoCap) of two highly-skilled black belt karate athletes consisting of 560 recordings of various karate techniques acquired with wearable sensors. We have evaluated the quality of generated templates; we have validated the matching algorithm that calculates similarities and differences between various MoCap data; and we have examined visualizations of important differences and similarities between MoCap data...

BACKGROUND: Persistent bouts of extended exercise and heavy training are associated with depressed immune cell function. It has recently been demonstrated that IL-6 is produced locally in contracting skeletal muscles and acts on a wide range of tissues. Larger amounts of IL-6 are produced in response to exercise than any other cytokines. Though the majority of existing data obtained following prolonged exercise, it remains to be explained the effect of martial arts training on IL-6 and other immunological parameters and associated changes to the duration of this type of exercise...

Children and adolescents may participate in sports that favor a particular body type. Some sports, such as gymnastics, dance, and distance running, emphasize a slim or lean physique for aesthetic or performance reasons. Participants in weight-class sports, such as wrestling and martial arts, may attempt weight loss so they can compete at a lower weight class. Other sports, such as football and bodybuilding, highlight a muscular physique; young athletes engaged in these sports may desire to gain weight and muscle mass...
