Strength andConditioning for MuayThai AthletesAnthony N. Turner, MSc, CSCSLondon Sport Institute, Middlesex University, London, EnglandSUMMARYMUAY THAI WAS DEVELOPED INTHAILAND AND IS A COMBATSPORT IN WHICH CONTESTANTSCAN KICK, PUNCH, KNEE, ELBOW,AND GRAPPLE WITH THEIROPPONENTS. LIKE MOST MARTIALARTS, MUAY THAI ATHLETES TENDTO PLAY THEMSELVES FIT, OFTENBECAUSE THIS HAS LONG BEENTHE TRADITIONAL APPROACH BUTALSO BECAUSE OF THE MANYMYTHS THAT SURROUNDGYM-BASED TRAININGEXERCISES. THIS PAPERTHEREFORE AIMS TO JUSTIFY THEINCLUSION OF STRENGTH ANDCONDITIONING WITHIN MUAY THAIAS AN INTERVENTION TO FURTHERENHANCE ATHLETICPERFORMANCE. IN ADDITION, ANEVIDENCE-BASED PROGRAM ISSUGGESTED.INTRODUCTIONuay Thai, literally Thai boxing, was developed in Thailand and is known as the artof 8 limbs. Athletes can kick, punch,knee, elbow, and grapple with theiropponents. A Muay Thai match lastsup to 5 rounds of 3 minutes but isoften manipulated depending on theskill of the athletes. As in mostmartial arts, contestants are weightmatched.MIn Muay Thai and more than likelyboxing and most martial arts, fitness78appears to be gained through a traditional combination of running, padwork, and sparring. Most athletes arereluctant to undergo strength trainingbecause of fears of a loss in flexibilityand a gain in body mass. The latterpoint is especially important andprovides for a significant barrier, asathletes will often aim to compete attheir lowest possible weight to fightopponents of lower mass.The aim of this paper therefore was torationalize the use of strength andconditioning (S&C) within Muay Thaiand dispel any myths that prevent thisform of intervention. The paper furtheraims to describe and rationalize ‘‘gymbased’’ methods to further enhanceathletic performance and finally present the reader with an evidence-basedS&C program.PERFORMANCE ANALYSISAs with any sport to which S&Cinterventions are to be implemented,the S&C coach must first undergo aperformance analysis (also referred toas a needs analysis) to identify thebiomechanical and physiological requirements of the sport. Following this,the S&C coach must construct anappropriate test battery to measurethe strengths and weaknesses of theathlete against these variables. Inaddition, it is fundamental to identifymechanisms of injury and prehabilitative strategies. Finally, through consultation with the athlete and sportscoach, individual goals must beidentified.VOLUME 31 NUMBER 6 DECEMBER 2009BIOMECHANICAL ANALYSIS OFMUAY THAISTRIKINGThe straight, hook, and uppercut(Figures 1–3, respectively) are the 3principle punches used in Muay Thaiand are identical to those used inboxing. Each punch involves tripleextension whereby the ankle, knee,and hip extend to generate force fromthe ground. Using the additional linksof the kinetic chain, the trunk, shoulder, and arm, they then apply this forceto the opponent. The need for thissynchronization can be evidencedfrom studies conducted by Filimonovet al. (33) and Verkhoshansky (101).Filimonov et al. (33) analyzed thestraight punch of 120 boxers, rangingfrom elite to junior ranks. All boxerswere instructed to perform a straightright to the head, ‘‘maximally fast andpowerful.’’ The results of this study areillustrated in Table 1 where it can benoted that elite level boxers predominately generate force from the legmusculature, whereas lower rankedboxers generate the majority of forcefrom the trunk and arms. This findingis corroborated by data acquired byVerkhoshansky (101) who showed thatwith mastery in the shot put, whichmay be considered biomechanicallysimilar to a straight punch, the emphasis gradually shifts from theKEY WORDS:Muay Thai; boxing; martial arts;combat; power; strength; ballistic;plyometrics; testingCopyright Ó National Strength and Conditioning Association

As illustrated in Figures 4–7, Tripleextensions movements are also requiredfor kicking, kneeing, and elbowing. Thedevelopment of this synchronizationand use of triple extension–based exercises may therefore be consideredessential to the generation of forcewithin Muay Thai. Weightlifting andthe associated lifts are often hypothesized to provide an appropriate stimulusfor motor skills requiring triple extension (52,59,61,93). Moreover, the second pull position (Figure 8) providesa biomechanical comparison with thepunching start position; therefore, sportspecificity can be further gained bycommencing lifts from this position.Figure 1. Straight.shoulder to the leg musculature. Thisinvestigation revealed that for beginners, the correlation between athleticachievements and strength of the armmuscles is 0.83 and with leg strength is0.37. For highly qualified athletes,however, the correlations were 0.73and 0.87, respectively.To further facilitate the development ofoptimal synchronization patternswithin the kinetic chain, and assist inthe carryover of triple extension–basedexercises to Muay Thai techniques,a derivative of complex training,termed ‘‘carry-over training,’’ is recommended (see 25,27 for a review ofcomplex training). In this context,however, the objective is not thepotentiation of force (although thismay be an outcome) but rather thecarryover of neuromuscular stimulus/firing sequence. For example, an athletemay perform a set of power snatches(often from the second pull/hang),followed by performing straightpunches to the bag during the restperiod. The athlete is encouraged tovisualize the carryover and draw comparisons with the 2 forms of tripleextension and in effect, regard thepunch as synonymous with the powersnatch. It is important to only performa few punches (usually 3 per arm) andensure the emphasis lies with powergeneration with enough rest betweenreps to minimize fatigue. It is hypothesized that this will assist in neuraldevelopment and carryover, ultimatelyfacilitating an increase in force production when striking. This form ofcarryover training is currently beingtested within our laboratory to providean objective assessment of its validity.REACTIVE STRENGTHFigure 2.

S&C for Muay ThaiOptimization of SSC mechanics dictates that these movements, which (inthe opinion of the author) may beconsidered biomechanically similar tosprint running (whereby the knee is‘‘punched’’ forward and then the leg isquickly driven back down into theground), require that ground contactbe made via a forefoot landing only(51,69), thus minimizing ground contact time (GCT; 4,55,71), increasingenergy return (and thus striking force;51,69) and rate of force development(RFD; 13), and reducing the durationand metabolic cost of movement(11,12,24,100,102).Figure 3. Uppercut.capabilities of an athlete, may also beconsidered fundamental to force generation within Muay Thai. It is welldocumented that efficient SSC mechanics result in enhanced propulsiveforces (11,14,15) and conservation ofenergy (12,100,102), and this thereforesuggests that within martial arts, thismay translate into enhanced powerand power endurance of striking. As anexample, double kicks or consecutiveknees to an opponent require that aftereach strike, the leg is quickly drivenback down into the ground and thenquickly driven back up toward theopponent. In addition, when the athlete wants to deliver a powerful strikewith the front leg, they must firstswitch stance (change from a left footforward, right foot back stance, toa right foot forward, left foot backstance), thus allowing the kicking leg todevelop sufficient power through theSSC mechanism (Figure 9–11).This SSC efficiency, however, isa learned ability gained through thegeneration of muscle stiffness, therebyoptimally using the elastic recoil properties of the tendon (3,24,53,55,70,73).Muscle stiffness, however, is under thesubconscious control of the nervoussystem, whereby the Golgi tendonorgan (GTO) inhibits the generationof high forces (and muscle stiffness) asa protective mechanism against the riskof injury (88). Through observationsmade by this author, most athletes donot train SSC mechanics (enablingGTO disinhibition) beyond that gainedfrom their sports practice. This isillustrated by the fact that the majorityof athletes make heel contact, which issuggestive of a prolonged amortizationphase and muscle compliance consequent to GTO inhibition (34).It appears evident therefore thatsports practices do not provide sufficient stimulus for this adaptationand that purposeful exercises suchas plyometrics must be includedTable 1Level of mastery and the contribution to punching force by key components of the kinetic chain (33)Arm extension(%)Trunk rotation(%)Push off with extensionof back leg (%)Total(%)Masters of sport and candidatesfor masters of sport24.1237.4238.46100Class I25.9441.8432.22100Classes II and III37.9945.5016.51100Category80VOLUME 31 NUMBER 6 DECEMBER 2009

Figure 4. Elbow.(72,75,78,82,85,88,90). For example,Kyrolainen et al. (72) reported that 4months of plyometric training, consisting of various jumping exercises suchas drop jumps, hurdle jumps, andhopping, was required for the disinhibition of the GTO and the generationof muscle stiffness (concurrent withpre-activation tensioning and antagonistic cocontraction). Moreover, aswell as takeoff velocity increasing by8%, energy expenditure decreased by24% suggesting that adaptations fromthis plyometrics protocol also resultedin a reduction in the metabolic cost ofthese movements (72). It appearsapparent therefore that chronic plyometrics training is required to not onlycondition the Muay Thai athlete toincrease striking forces of this naturebut also facilitate them in employingthese strikes with regularity (aid thedevelopment of power endurance).Finally, inherent to plyometric exercises is the powerful execution of tripleextension (as previously described), sothese exercises are also likely to havea carryover to kicking and punchingmechanics and striking power.Figure 5. Push kick.Appropriate plyometric drills includedrop lands (Figure 12; ensuring theathlete initiates the exercise by stepping from the box, Figure 13) wherebythe body is hypothesized to adapt tohigh landing forces (eccentric loads)and disinhibition of the GTO is learned(105). This drill may then be progressedto drop jumps whereby the focus shiftsto reducing the amortization phase andGCT and thus the loss of elastic energy(34). It may be prudent, however, tocommence plyometric training withankling/stiff leg hops (Caption 1),which enhance the stiffness of theankle joint, as overall leg stiffness hasbeen reported to largely depend onankle stiffness (4,31,32). Of course, theS&C coach must determine safe andconducive plyometric intensities (e.g.,drop height). It may be appropriatetherefore to first practice landing drillsby jumping up to a box (Figure 14) orsimply jumping forward along theground, as the intensity of each is lessthan when dropping from a box.Strength and Conditioning Journal www.nsca-lift.org81

S&C for Muay Thaipowerlifting (i.e., back squat, deadlift,and bench press) produce approximately 12 W/kg of body weight (40).However, during the second pull phaseof both the clean and the snatch, anaverage of 52 W/kg of body weight isproduced (40).Figure 6. Roundhouse kick.FORCE GENERATIONCHARACTERISTICSBoxing movements (i.e., punches) involve contraction times of 50–250 ms(1). As described earlier, GCT duringdouble kicks and knees should (anecdotally) resemble that of sprint runningwhere this has been reported to be 101ms (77). Muay Thai motor skillstherefore, like the vast majority ofathletic movements, occur within250–300 ms (93,104) and the opportunity to develop peak force, whichmay require up to 600–800 ms (29,68),is not a time luxury afforded to theseathletes. This therefore suggests theneed for these athletes to developpower.It is hypothesized that if the timeavailable for force development is lessthan 0.3 seconds (as is the case in MuayThai), training should focus on improving RFD (80,87,105). BecauseRFD is a function of neuromuscularactivation (86) and is representative ofan individual’s ability to accelerateobjects (87), many authors recommendballistic (explosive) training to improvethis quality (10,43,45,46,103). It is82generally recognized that althoughheavy resistance training improvesthe final height of the force-time (FT) curve, ballistic training improves theslope of the initial portion of the F-Tcurve, specifically within the first 200–300 ms (45,80) when striking is mostlikely to occur.Ballistic exercises can best be describedas explosive movements (rapid acceleration against resistance) whereby thebody or object is explosively subjectedto full acceleration. Reviews by Flanagan and Comyns (34) and Hori et al.(58) recommended the use of plyometric training and weightlifting, respectively, to train RFD, as in additionto their ability to be adapted to thespecifics of the sport, they encouragefull acceleration with zero velocityachieved only by the effects of gravity.In addition, weightlifting producessome of the highest power outputs ofany exercise modality. For example,Garhammer (40) reported that thesnatch and clean and jerk exhibit muchgreater power outputs compared withthe squat and deadlift. For example, therelatively slow velocities involved inVOLUME 31 NUMBER 6 DECEMBER 2009It should be noted that a high and positive correlation exists between peakpower and maximum strength (r 0.77–0.94; 6), illustrating the significance of strength training as a prerequisite to power development. Withthis in mind and because strengthlevels may only be maintained forapproximately 2 weeks (60), it isadvisable to include strength sessionsthroughout the entirety of a periodizedprogram so as to optimize and maintain high levels of power output. Infurther support of using a combinedstrength and power training approach,Cormie et al. (21), Harris et al. (50), andToji et al. (96) concluded that whenconsidering the improvement of a widevariety of athletic performance variablesrequiring strength, power, and speed,combination training produces superiorresults (compared with strength trainingonly and power training only). Thepremise of this approach is thought toresult from the additive improvementsin both maximum force (throughstrength training) and maximum velocity (through power training), thusleading to a greater enhancements inpower output across the entire forcevelocity curve (96).Finally, because most movementswithin Muay Thai are performedunilaterally, this should therefore betrained accordingly to increase thesport-performance carryover. This suggestion is corroborated by Coyle et al.(23) and Vandervoort et al. (99) whoreported the existence of a bilateraldeficit whereby when the limbs areworking together, their net force issmaller than the combined total ofwhen each limb is working independently. Ballistic movements therefore,such as plyometrics, should advance toincorporate unilateral movements andbarbells should be progressed todumbbells.

populations, maximal strength gainsare elicited at a mean training intensityof 85% 1 repetition maximum (1 RM),#6 reps, 2 days training per week, andwith a mean training volume of 8 setsper muscle group (81). In addition, abuildup of lactate and hydrogen ionsshould be avoided as these are a contributing factor to the release ofanabolic hormones and subsequentmuscle hypertrophy (and thereforebody mass; 41,47). These metabolicby-products may be dissipated withlong rest periods and/or alternatingbody parts in a set for set or exercise forexercise format. For example, an athlete can alternate between upper-bodyand lower-body exercises or betweenagonist and antagonist exercises.PHYSIOLOGICAL DEMANDS OFMUAY THAIScientific data on Muay Thai are currently unavailable, therefore deductionsmust be based on empirically similarsports. In the opinions of the author,sports such as wrestling, fencing, boxing,and mixed martial arts (MMA) providefor a good comparison. In addition,Cordes (20) compares boxing withbasketball, therefore this will also beconsidered. Table 2 illustrates the primary metabolic demands of these sportsas described by Ratamess (84).Figure 7. Knee.REPS, SETS, INTENSITY, AND RESTLike most sports, developing an athlete’s power output is considered a keycomponent to successful sports performance (as most activities are force andtime dependent). Because power production is largely a consequence ofefficient neuromuscular processes,quality should be stressed at all times.Therefore, the effectiveness of a powerprogram may be related to the qualityof each repetition. It has been hypothesized that each repetition shouldachieve 90% of maximum poweroutput or velocity (36) and that this,anecdotally, is best achieved with theuse of 3 reps per set, at least 3 minutesrest between sets (7,36) and a maximumof 5 sets (36). An additional method toensure quality of repetitions is throughthe use of cluster training (44). Thisform of training involves interrepetition rest intervals of between 10 and 30seconds (interval length depends onexercise complexity) whereby thequality of performance is enhancedthrough decreases in repetitioninduced fatigue. This method thereforeshould be used for both power/ballistictraining and strength training.From the information presented aboveand through empirical observations,Muay Thai involves predominate anaerobic energy contribution and thespeed and explosive nature of the sportfurther suggests phosphogen systemdominance. In addition, rounds arefewer than boxing (5 versus 12) andshorter than both wrestling and MMA(3 versus 5 minutes). Therefore, aerobic energy system contribution may beminimal and be involved only in ringmovement and recovery mechanisms.As previously mentioned, strength isthe prerequisite to power and thereforeadequate strength training must beincluded. However, as Muay Thai isweight classed, S&C coaches shouldaim to increase athletic strength without concomitant increases in musclecross-sectional area. For athleteThese findings likely suggest that roadrunning is detrimental to Muay Thaiperformance and unfavorably altersenergy system adaptations. This is inagreement with Hoffman et al. (58)who analyzed basketball competitionsover a 4-year period and reported thataerobic capacity had a significantStrength and Conditioning Journal www.nsca-lift.org83

S&C for Muay Thainegative correlation to performance.This is further corroborated by authorswho suggest that once an aerobic baseis achieved, sport-specific team practices and games are sufficient to maintain aerobic fitness in anaerobicdominant sports (17,56,57). Trainingprograms therefore need to be directedtoward high-intensity training such asinterval and repetition training. Manyathletes, however, use long distancerunning as a means to rapid weight loss(RWL). This, however, may be to thedetriment of sports performance andperhaps more emphasis needs to beplaced on nutritional interventions (butthose based on scientific research). RWLis briefly discussed later in this text.Figure 8. Second pull position.Figure 9. Front leg knee starting position.84VOLUME 31 NUMBER 6 DECEMBER 2009In summary of the above, therefore,interval training may be the optimalintervention to bring about efficaciousadaptations within the metabolic system. Anecdotally, sparring providesthe most specificity and optimallyadapts the energy systems for thepurposes of competition. However, itis not always reasonable to call on thisintervention. Therefore, again anecdotally, it is suggested that coaches usea ‘‘5 s on 5 s off’’ protocol termed‘‘Combat Intervals.’’ For this, athleteshit the pad for 5 seconds and then restfor 5 seconds throughout the entiretyof a round. This time frame was chosento represent the amount of time anathlete may attack for. The pad mancan of course manipulate each intervalby increasing or decreasing the timethe athlete is attacking or resting (orboth). Empirically, it is challenging forthe pad man to continually use timesless than 5 seconds. The pad man canalso change the type of strikingcombinations between intervals andeven attack during the rest periodcausing the athlete to defend andfurther increasing the intensity. Finally,it is recommended that the athlete uses2-hit striking combinations only, forexample, straight then hook, left uppercut then right roundhouse kick.This is to ensure a fast and continuingrhythm when attacking the pad. Itshould be noted that the S&C coachshould not be considered responsible

therefore, between the combat athletes’ perception that RWL is associated with good performance, and theresearch that consistently demonstrates that athletes perform significantly below expectations. Thisperception may be explained by thefact that an athlete can win a contestdespite performing below expectations(48). After all, both contestants likelyunderwent a RWL intervention.PERFORMANCE TESTINGFigure 10. Front leg knee—the athlete switches stance.for delivering this aspect of training;however, it is important to note thatthese are suggestions that can be madeto the sports coach.RAPID WEIGHT LOSSResearch investigating the consequences of making weight in combat sportssuch as wrestling (42,54,56,65,67) andboxing (48) has shown that RWL isassociated with concurrent decrementsin performance. This may be becauseof dehydration (97), depleted glycogenstores (19,94), reduced lean musclemass (66), and negative mood(48,66,91). Significant to the latterfactor, mood has been shown to bean effective predictor of performance incombat sport with 92% of winning andlosing performances in karate correctlyclassified from precompetition mood(95). Losing karate performance wasassociated with high scores of confusion, depression, fatigue, and tensioncoupled with low vigor scores (95).There appears an evident paradox,Testing enables coaches to identify thephysical capabilities of their athletes.This further enables coaches to monitor the efficacy of the programs(allowing adjustments accordingly)and make predictions on competitionperformance. Based on the needsanalysis conducted above, a suggestedbattery of tests has been identified andis illustrated in Table 3.It is important to conduct the tests inthe order described in Table 3 as thiswill reduce the negative effects ofaccumulated fatigue as the athleteprogresses through the testing battery.This is in agreement with Harman (49)who suggests that for these reasons,tests should be conducted in thefollowing order: nonfatiguing tests(e.g., anthropometry), agility, maximum power and strength, sprint tests,local muscular endurance, anaerobic,and then finally aerobic capacity tests.RISK OF INJURYAgain deductions must be based onempirically similar sports. For example,within wrestling, injuries occur predominately at the knee, shoulder, andankle (63). Within boxing, injury is morelikely at the shoulder, elbow, wrist/hand, low back, and neck (30). This iscorroborated by Cordes (20) whosuggests that injury occurs primarily atthe hand and wrist, followed by shoulder then elbow. However, the knee,ankle, leg, and foot are also at risk.Figure 11. Front leg knee strike.The author is of the assumption thatmany of the athletes from whom thesedata were gathered were not undertaking efficacious S&C programs. Withthis assumption in mind, strengthtraining may have reduced theStrength and Conditioning Journal www.nsca-lift.org85

S&C for Muay Thaimovement skills. This enhanced eccentric strength may have defensivebenefits through absorbing blows (20).For example, impact to brain dependson the acceleration and rapid turn of thehead (20). A stronger neck, especiallyeccentrically, can help absorb forces.This is also likely to be true of the armsthat are often up to guard the face.Specific to the former point, it may beconcluded that Muay Thai athletes perform exercises specifically for the neck.As well as preventing injury, this mayalso prevent the occurrence of knockouts. Cordes (20) also suggests thatknockouts resulting from blows to thethorax or abdomen may be less likelywith the addition of strength training.The S&C coach is also advised tocheck for movement dysfunctionswithin the kinetic chain. For example,much research has centered aroundgluteus medius dysfunctions (8,26,38,39,83,89,98). However, this, along withmany other factors that are likely tocontribute to the occurrence andreoccurrence of injury within thissport, is beyond the scope of this paper.STRENGTH AND CONDITIONINGPROGRAMFigure 12. Drop land.incidence of these injuries through itspositive adaptations on the structuralintegrity of all involved joints. Forexample, as well as an increase inmuscle strength, tendon, ligament, andcartilage strength would also increasealong with bone mineral density(35,37,92). Furthermore, boxers tendto use (and therefore develop) theanterior musculature more than theposterior (2), thereby leaving themexposed to muscle strains in the weakermuscles. S&C training can ensurethe development and maintenance ofproper ratios. Most significantly andpertinent to performance, increasingantagonist muscle strength may increase movement speed and accuracy86of movement (62). This has been hypothesized to occur because of alterationsin neural firing patterns, leading toa decrease in the braking time andaccuracy of the limbs in rapid ballisticmovements (62). Therefore, strengthbalance is needed to break the agonistssuccinctly in rapid limb movements.When one muscle or movement actionis stronger than its antagonist’s, performance may be compromised. Thisis likely to provide the athlete witha greater source of motivation todevelop the posterior musculature thanthat of reducing the risk of injury alone.In addition, strength training, unlikesports training (e.g., pad work, sparring), will train the eccentric phase ofVOLUME 31 NUMBER 6 DECEMBER 2009The following program (Tables 4 and5) is based on 2 S&C sessions per week(as this anecdotally appears to be themean training time allocated/availableto S&C training for these athletes) andhas been developed based on thereviewed research. Plyometrics (to develop the SSC mechanism) or carryover training (see previous text) isperformed during most rest intervalsand the selected drills should bealternated to avoid neural monotony,thereby ensuring the neuromuscularsystem is continually challenged todevelop. This ‘‘complex training’’ approach (performing ballistic exercises inthe rest period) is a valuable tool toS&C coaches who are limited to 1 or 2S&C sessions per week as it enablesthem to effectively use the rest periodwithout detriment to performance(28). As previously described, plyometric drills should be logically progressedto ensure appropriate overload and an

ethos of quality over quantity should beenforced.Strength exercises should be prescribedat intensity slightly below the maximum intensity for that prescription ofrepetitions. This point was concludedin a meta-analysis conducted byPeterson et al. (81) where it wasrevealed that training to failure doesnot elicit greater gains than not trainingto failure, and in addition, athletes areless likely to overtrain. Finally, for allpower exercises, the load should bevaried as this will also vary the velocityand further increase sport specificity.Although it is well understood thatpeak power output occurs at 80% 1RMin weightlifting (namely the powerclean, 22) and using body mass onlyfor squat jumps (22,76), it is likely thatthis is of greater theoretical relevancethan practical significance.Finally, it is important to address theissue of flexibility. The athlete andcoach should be assured that providingweight training is performed using thefull range of motion, flexibility will notbe lost (9,64) and may even be increased (9,74). This can be furthercorroborated by data collected at oneof the Olympic games wherebyweightlifters were second only togymnasts in a battery of flexibility tests(64). Moreover, in shoulder flexion,a movement specific to the snatch andjerk, their flexibility was significantlybetter than any other group. Therefore,the persistent myth that weight training negatively affects flexibility is unfounded and is most likely based onbodybuilding athletes who may haveFigure 13.

The athlete is usuallytested over the following drop heights: 30, 45, 60, and 75cm (79). Efficient SSC mechanics should result in greater jumpheights from greater drop heights (also reflected by the RSI score).
