BACKGROUND: Athletes' recovery is important in improving their performance. Nutritional strategies can be effective in enhancing recovery rate. Choosing the best food items in appropriate intervals can play effective roles in resynthesis of fuels and recovery of muscle injury. Beverage micro and macronutrient content are helpful in fuel restoration. In this study, we assess the effects of various kinds of beverages on oxidative stress, muscle injury, and metabolic risk factors in taekwondo players...

Reaction time and response time are considered important abilities and can potentially affect combat performance. This study investigated the effect of a specific fatigue protocol on reaction time, response time, performance time, and kick impact. Seven male athletes reported to the laboratory on two different days. During day one, athletes performed a specific progressive taekwondo test, and on day two, a protocol for determining reaction time, response time, performance time, and kick impact before and after a time to exhaustion test at an intensity level corresponding to the maximal kick frequency obtained during the specific progressive taekwondo test...

The aim of the present study was to examine how a 4-week exercise program affects the serum levels of certain cytokines in Taekwondo athletes. The study involved 10 elite male Taekwondo athletes (mean age, 20.67±0.24 years; mean weight, 65.45±1.69 kg) who were studying at the Physical Education and Sports High School of Selçuk University (Konya, Turkey) in June 2014. The subjects were involved in a Taekwondo exercise program on every weekday for 4 weeks. The subjects were also engaged in an exercise to exhaustion session twice; once before starting the 4-week exercise program and once upon completion of the program...

BACKGROUND: Taekwondo is a martial art and a combat Olympic sport. Similar to other types of combat sports, Taekwondo fights are conducted between opponents grouped by sex, age and weight classes. Disordered eating behaviors are common in combat sports with weight classes, attributed to the athletes' need to remain within a specific weight range. Pre-competition rapid weight loss (RWL) is also common, and entails a health risk. AIM: To assess the eating attitudes and the prevalence and techniques of RWL among young Taekwondo fighters...

PURPOSE: The purpose of this study was to determine the prevalence of symptomatic femoroacetabular impingement (FAI) in athletic patients. MATERIALS AND METHODS: From July 2003 to May 2013, 388 patients (422 hips) who underwent arthroscopic surgery for FAI were evaluated demographic characteristics. The patients' age, gender, diagnosis, and type of sports were analyzed using medical records and radiography. RESULTS: Among 422 hips in 388 patients, 156 hips were involved with sports...

PURPOSE: The purpose of this study was to determine the interaction of ACTN3 gene polymorphism and muscle imbalance effects on kinematic efficiency changes in combat sports athletes. METHODS: Six types of combat sports athletes (Judo, Taekwondo, boxing, kendo, wrestling, and Korean Ssi-reum) participated in the study. ATCN3 gene polymorphism and muscle imbalance in lower extremity were evaluated followed by analysis of differences of moment in hip, knee, and ankle joint during V-cut jumping and stop...

Changes in an athlete's physiological and health metabolic profiles after detraining have not been studied in elite Taekwondo (TKD) athletes. To enable a better understanding of these physiological changes to training cessation, this study examined the effects of 8-weeks detraining on the aerobic capacity, body composition, inflammatory status and health metabolic profile in elite TKD athletes. Sixteen elite TKD athletes (age: 21.0 ± 0.8 yrs, BMI: 22.4 ± 3.9 kg/m2; Mean ± SD; 11 males and 5 females) participated in this study...

BACKGROUND: The purpose of this study was to compare the acute effects of different stretching types on sprint performance in taekwondo practitioners. METHODS: Twelve male taekwondo practitioners performed stretching exercises using different types (ballistic, proprioceptive neuromuscular facilitation (PNF), static stretching) in a random order at three-day intervals; there was also a control condition involving no stretching exercises. The subjects performed 2 maximal 20m sprints (with 10m split times also recorded) with a recovery period of 1 minute immediately post stretching and at 5, 10, 15 and 20 minutes after stretching...

This study investigated the prevalence, magnitude, and methods of rap-id weight loss among male and female Taekwondo athletes from all competitive levels. A questionnaire was administered to 72 men (regional/state level, n=31; national/international level, n=41) and 44 women (regional/state level, n=9; national/international, n=35). Among the male athletes, 77.4% of the regional/state level and 75.6% of the national/international athletes declared to have reduced weight to compete in lighter weight categories...

I-Fan Chen, Huey-June Wu, Chung-Yu Chen, Kuei-Ming Chou, Chen-Kang Chang
BACKGROUND: The decline in cognitive performance has been shown after fatiguing exercise. Branched-chain amino acids (BCAA) have been suggested to alleviate exercise-induced central fatigue. Arginine and citrulline could remove the excess NH3 accumulation accompanied with BCAA supplementation by increasing nitric oxide biosynthesis and/or urea cycle. The purpose of this study is to investigate the effect of the combined supplementation of BCAA, arginine, and citrulline on central fatigue after three simulated matches in well-trained taekwondo athletes...

OBJECTIVES: In taekwondo competitions, fatigue has a large influence on performance. Recent studies have reported that the excitability in the primary hand motor cortex, investigated with transcranial magnetic stimulation (TMS), is enhanced at the end of a maximal exercise and that this improvement correlates with blood lactate. The aim of the present study was to investigate the relationship between blood lactate and cortical excitability in taekwondo athletes and non-athletes. METHODS: The excitability of the primary motor cortex was measured before and after fatiguing hand-grip exercise by TMS...

BACKGROUNDː To estimate the prevalence of chronic overuse pain (COP) and to identify possible risk factors of COP in sport-poomsae-Taekwondo. METHODSː This is a cross-sectional survey. A total of 263 sport-poomsae competitors (112 females; 151 males; aged between 12-44 years), who competed at the 2014 sport-poomsae- Taekwondo competition, participated in this study. The prevalence rate of COP and possible risk factors associated with COP were analyzed by using Chi-square tests and independent t-tests. RESULTSː A total of 173 athletes reported that they experienced COP (65...

This case describes the utilization of spinal manipulative therapy for an acute athletic injury during a Taekwondo competition. During the tournament, an athlete had a sudden, non-traumatic, ballistic movement of the cervical spine. This resulted in the patient having a locked cervical spine with limited active motion in all directions. The attending chiropractor assessed the athlete, and deemed manipulation was appropriate. After the manipulation, the athlete's range of motion was returned and was able to finish the match...
