Post any study related to the sport of muay thai.
Edit: Not many studies on Muay thai. Kickboxing seems to have the greatest number of studies.
x. Physiological responses and energy cost during a simulation of a Muay Thai boxing match
Muay Thai is a martial art that requires complex skills and tactical excellence for success. However, the energy demand during a Muay Thai competition has never been studied. This study was devised to obtain an understanding of the physiological capacities underlying Muay Thai performance. To that end, the aerobic energy expenditure and the recruitment of anaerobic metabolism were assessed in 10 male athletes during a simulation match of Muay Thai. Subjects were studied while wearing a portable gas analyzer, which was able to provide data on oxygen uptake, carbon dioxide production, and heart rate (HR). The excess of CO2 production (CO2 excess) was also measured to obtain an index of anaerobic glycolysis. During the match, group energy expenditure was, on average (mean ± standard error of the mean), 10.75 ± 1.58 kcal·min-1, corresponding to 9.39 ± 1.38 metabolic equivalents. Oxygen uptake and HRs were always above the level of the anaerobic threshold assessed in a preliminary incremental test. CO2 excess showed an abrupt increase in the first round, and reached a value of 636 ± 66.5 mL·min-1. This parameter then gradually decreased throughout the simulation match. These data suggest that Muay Thai is a physically demanding activity with great involvement of both the aerobic metabolism and anaerobic glycolysis. In particular, it appears that, after an initial burst of anaerobic glycolysis, there was a progressive increase in the aerobic energy supply. Thus, training protocols should include exercises that train both aerobic and anaerobic energetic pathways.
x. THE ASSESMENT OF THE FA?LURE AND SUCCESS CASES OF THE SPORTMEN PARTICIPATING TO MUAI-THAI TURKEY CHAMPIONSHIP
Objective: This research is made to determine the factors which affect the succsess and failure of the sportsmen
competing at elite level in the branch of Muay-Thai in Turkey championship.The universe of the research involves
Muay-Thai sportsmen at elite level and participating to Turkey Championship.The sampling group is constitued by 80
successful and 80 unsuccessful sportsmen in Turkey Championship.
Method: In the research, a survey has been made to determine the factors affecting sportsmen’s success and
failure and by intervieving face to face with sportsmen participating to competition, datas have been collected.The
findings have been analyzed stastically by using frequency method.
Discussions and Conclusion: After the research which has been made to determine the factors affecting the
success and failure of sportsmen participating to Muay-Thai Turkey Championship, has been carried out, it can be
conclued that while many factors are well to the fare in successful sportsmen, in failed sportsmen motivation, stress,
regular training and lack of strategy are well to the fare.
x. Conditioning Strategies for Competitive Kickboxing
IN CONJUNCTION WITH SPORT-SPECIFIC SKILLS DEVELOPMENT, SUFFICIENT NUTRITION, REST, AND PSYCHOLOGICAL READINESS, A KICKBOXER'S SUCCESS IS CONTINGENT UPON HIS OR HER LEVEL OF CONDITIONING. ON THE BASIS OF THE METABOLIC DEMANDS OF COMPETITIVE KICKBOXING, TRAINING SHOULD TAX BOTH THE ANAEROBIC AND AEROBIC SYSTEMS EXTENSIVELY. IN TANDEM WITH PROPER CONDITIONING, INJURY MAY BE PREVENTED THROUGH PREHABILITATIVE EXERCISES AND ADHERENCE TO SAFETY MEASURES.
x. Relation Between Blood Lactate Levels, Heart Rate, And Rating Of Perceived Exertion In Kickboxing: 436 Board #27 2:00
Blood lactate has been shown to be a reliable tool to monitor the exercise intensity and fatigue level. However, heart rate (HR) seems to be more convenience and noninvasive index compared with blood lactate.

PURPOSE
To examine the relation between blood lactate levels (BL), HR, and rating of perceived exertion (RPE) in professional kickboxers during different periods of competition.

METHODS
12 male and 11 female professional kickboxers (mean ± SD; age 20.1 ± 1.8 years; height 173.2 ± 5.9 cm; body mass 62.0 ± 1.5 kg) participated in this study. The BL, HR and RPE were measured before, during and after the match at national level competition. Subjects also performed incremental cycling test until exhaustion at which similar measurements were made.
Back to Top | Article Outline
RESULTS
There was a moderate correlation between BL and HR before, during and after the match, and the maximal relative coefficients were 0.87 (P<0.05) in male and 0.93 (P<0.05) in female. BL was highly correlated to HR during the last 3 rounds (P<0.05) during the match. Similar result was found in cycling trial. Whereas, the relation between BL and RPE was low, with the maximal relative coefficients were 0.37 in male and 0.33 in female (P>0.05). The relation between HR and RPE was also not significant.

CONCLUSION
The results reconfirmed that there is a close relationship between HR and BL during kickboxing. HR could be viewed as a valid tool to monitor the exercise intensity and fatigue level during the game.
x. Physiological analysis of the characteristics of energy supply for Sanda athletes
In order to gain an insight into the characteristics and affecting factors of energy supply in the Sanda event,the authors used 26 class one and class elite Sanda athletes as the experimental subjects(ESs),and 42 class one athletes for such 6 events as 100-1,500 m runs as the controls,measured and analyzed such indexes as coeffi-cient of urine creatinine,gaseous(energy) metabolism,blood lactic acid concentration after the game,individual lactic acid threshold,as well as average fighting time per fight and non-fighting time per break in Sanda competi-tion,and revealed the following findings: the total fighting time in each round is 28.6% of the game time in each round,while the total break(non-fighting) time is 71.4% of the game time in each round;the total oxygen consump-tion for the fighting periods in 3 rounds is 8.338 L,while the total oxygen over consumption after the game is 46.162 L;these two consumptions are respectively 15.3% and 84.7% of their sum,which means that the oxygen deficit is too large;at peace,there is no significant difference between the coefficient of urine creatinine of the ESs and that of the athletes for 100 m and 200 m runs((38.8±7.9) mg/kg vs.(39.7±8.5) mg/kg vs(39.5±8.2) mg/kg,P0.05);the blood lactic acid concentration of the ESs immediately after each round of competition is significantly lower than that of the athletes for 400m and 800 runs;there is no significant difference between the individual lactic acid threshold of the ESs and that of the athletes for 200 m and 1 000 m runs(P0.05);there is a significant differ-ence between the maximum glycolysis capacity of the ESs and that of the athletes for 400 m and 800 m runs (14.53±2.31 vs.16.82±1.49 vs.16.65±2.23,P0.05). This study reveals that Sanda is a fast moving fighting event in which the energy is supplied primarily by the phosphagen system and secondarily by the lactic acid energy system.It is suggested that only by fully understanding the characteristics of energy supply for and the causes for the occur-rence of fatigue of the body of Sanda athletes can the basic physical constitution of the athletes be action specifi-cally improved in order to achieve an excellent performance.
x. Physiological and Anthropometric Profile of Elite Kickboxers
The anthropometric and physiological characteristics of kickboxers were investigated. Professional male middleweight (73-77 kg) and welterweight (63-67 kg) kickboxers were determined to have relatively higher aerobic capacities ([latin capital V with dot above]O2max, 54-69 ml [middle dot] kg-1 [middle dot] min-1), anaerobic capacities (8.2-11.2 W [middle dot] kg-1), and knee extension peak torques (2.8-3.3 Nm [middle dot] kg-1 @ 60[degrees] [middle dot] sec-1) than previously reported for many other power or combat athletes. Kickboxers also tended to be lean (6.1-10.8% BF) and were classified as mesomedial body types on the Health-Carter somatotype scale. This suggests that elite kickboxers demonstrate a high level of aerobic and anaerobic conditioning along with the ability to produce high muscle forces.
