The present study investigated the influence of cognitive, motor, and Karate (accordingly the guidelines of the German-Karate-Federation, DKV) training on the cognitive functioning and mental state of older people between 67 and 93 years of age. The three training groups each consisted of 12 elderly participants; the waiting control group included 9 participants. Before the training, participan...

OBJECTIVE To review the current evidence for the epidemiology of pediatric injuries in martial arts. DATA SOURCES The relevant literature was searched using SPORT DISCUS (keywords: martial arts injuries, judo injuries, karate injuries, and taekwondo injuries and ProQuest (keywords: martial arts, taekwondo, karate, and judo), as well as hand searches of the reference lists. MAIN RESULTS In g...

BACKGROUND Aging is associated with a decrease in physical skills, sometimes accompanied by a change in quality of life (QOL). Long-term martial arts practice has been proposed as an avenue to counter these deleterious effects. The general purpose of this pilot study was to identify the effects of an adapted karate training program on QOL, depression, and motor skills in 50-year-old men. METH...

PURPOSE This study aimed to compare physiological responses and time-motion analysis between official and simulated karate combat. METHODS Ten high-level karatekas participated in this study, which included official and simulated karate combat. RESULTS Karatekas used more upper-limb attack techniques during official combat compared to simulated ones (6±3 vs 3±1; P=0.05, respectively). For o...

INTRODUCTION Exercise induces renal hemodynamic alterations and stimulates electrolytes excretion. The purpose of this study was to assess urinary excretion of sodium and potassium in karate practitioners, following competitions. MATERIALS AND METHODS The study population composed of 18 healthy men, aged 18 to 21 years, with similar physical characteristics. They were professional karatekas w...

The purpose of this research was to identify the fighters' technical and tactical activity indicators in order to determine indicator significance regarding situational efficiency and designation between winning and losing performances in a karate match. We scientifically observed a sample of 274 male contesters of 137 karate matches during the 2008 World Karate Championship in Tokyo. Each indi...

In this note we analyse the potential of a system of four Dp-branes at arbitrary angles. The equilibrium configurations for various values of the relative angles and distances among branes are discussed. ∗On leave from Babes-Bolyai University of Cluj, Romania

—This study assessed how sex of participant is related to electromechanical delay during a karate punch. Ten male (M age = 25.00 yr., SD = 3.02; M height = 174.9 cm, SD = 6.3; M weight = 71.13 kg, SD = 9.35) and 8 female (M age = 27.4 yr., SD = 6.0; M height = 161.4 cm, SD = 5.1; M weight = 59.09 kg, SD = 7.00) karate athletes performed 10 ballistic punches to a target as hard as possible. Kine...

This study proposes a model using a Bayesian network to understand tactical behavior in Karate matches. The model is a probabilistic causal model consisting of the states of two competitors engaged in combat. Each state node of the model outputs a probability distribution of the occurrence of offensive, defensive, and evaluative actions. Using the model, we also propose an analysis method of Ka...
