Anthropometric And Physiological Profiles Of Sepak Takraw Players 

Conceptual 

Destinations: Anthropometric and physiological profiles of public sepak takraw not really set in stone. 안전놀이터

Strategies: Thirty nine players, having some expertise in the three playing positions (tekong/server, feeder, and executioner/spiker) were partitioned into three age classes of under 15 (U15), under 18 (U18), and under 23 (U23) years old. Stature, weight, percent muscle to fat ratio (%bf), greatest oxygen utilization (Vo2max), scope of movement (ROM), back and leg strength, and pulse, for the assessment of oxygen utilization during matches, were recorded. Factual investigation was performed utilizing one way ANOVA for free estimations and information are introduced as mean±standard deviation. 

Results: The U23 players were altogether taller and heavier with fundamentally better ROM of the neck, trunk, and lower leg joints and back and leg strength than the U15 players. No critical distinction was found in %bf between the three age classifications. Mean most extreme pulse during exercise was essentially higher in the U15 bunch when contrasted with the U18 and U23 gatherings (p<0.05). Mean Vo2max was comparable between the three gatherings. Assessed oxygen utilization during matches was 69.1%, 68.5%, and 56.4% of Vo2max in the executioner, tekong, and the feeder gatherings, individually. 

Ends: The mean tallness, body weight, and cardiopulmonary limits of the players were inside the Malaysian populace standards, however were to some degree lower than those of players of other court games from different nations. %bf was additionally lower in these players. This review gives the truly necessary anthropometric and physiological information of sepak takraw players for additional advancement of this game.

Following its presentation in the tenth Asian Games in Beijing in 1990, and as an exhibition sport in the 1998 Commonwealth Games in Kuala Lumpur, sepak takraw has become one of the quickest developing games in Asia and has spread to more than 20 nations including Argentina, Australia, Brazil, Canada, Korea, Germany, England, India, Japan, Puerto Rico, Spain, and the USA. The game is played on a space the size of a copies badminton court, with three players on each side of a 1.52 m high net (fig 1). A group comprises of three players: feeder, tekong/server, and spiker/killer.1

Sepak takraw joins ball abilities (kicking and shuffling) with the readiness and aerobatic moves of gymnasts and the instinctual reflexes of serious badminton players (fig 2). As in volleyball, there are passes, sets, and spikes however all without the utilization of hands or arms. The players are permitted to think carefully, chest, feet, and thighs to drive the ball over the net. Both setting and spiking is finished with the feet and the two most usually utilized spikes are the "sun back" spike (fig 3) and the "roll" spike (fig 4), which are performed loftily requiring gigantic deftness, accuracy, leg strength, timing, and ability. Like badminton, squash, and tennis, the force of the game is irregular, contingent upon the length of assemblies following a serve.

In spite of its expanding prevalence, to date just one paper has been distributed on the physical and physiological profiles of sepak takraw players.1 However, player profiling has turned into a vital interaction making progress toward greatness in sports. This review, hence, presents some data on the physical and physiological profiles of the players at the National Sepak Takraw Grand Prix 2002 Championship; these are the top sepak takraw players in the nation and some are in the public crew. 

Strategies Subjects 

39 male, sepak takraw players in state and public groups, were partitioned into three age classes of under 15 (U15; n = 12), under 18 (U18; n = 15), and under 23 years (U23; n = 12) old enough. All subjects gave informed assent and the college's morals panel supported the review. Anthropometric and cardiopulmonary boundaries still up in the air. 

Anthropometric estimations 

Stature and weight were estimated to the closest 0.5 cm and 0.5 kg, individually, utilizing a model 707 scale (Seca, Hamburg, Germany) with subjects standing unshod and wearing shorts or light apparel. Skin overlay thickness was estimated with a Harpenden caliper at four locales (mid-region, thigh, rear arm muscles, and suprailiac).2 The mean of three estimations addressed the incentive for each site. Percent muscle versus fat (%bf) was determined utilizing the four-site equation.3 

Back and leg strength 

Back and leg isometric strength was estimated utilizing a leg dynamometer (Takei Kiki Kogyo, Toyko, Japan). The subject remained on the stage with the storage compartment straight and the knees flexed to a point of 130–140°. Holding the handle bar with a pronated grasp, the subject pulled it gradually yet enthusiastically, broadening the knees and limiting the utilization of the lower back. Three endeavors were permitted with at least 60 s rest span between them. The scores for every one of the three endeavors were recorded with the best-pulled result taken as the proportion of solidarity (kg). 

Standing long leap 

Utilizing a standing long leap mat, the subject hopped maximally with a countermovement hop before take off. The distance (cm) from the departure line to the rear of the heel nearest to the departure line was recorded.4 A 2 min rest period was permitted between leaps to limit the impact of weariness. Standing long leap power was acquired by duplicating the distance hopped by weight. The scores of every one of the three leaps were recorded and best of the three leaps was taken as the proportion of the leap. 

Scope of movement 

The Leighton flexometer5 (Spokane, WA), a weighted 360° goniometer, was utilized to evaluate static scope of movement (ROM) of the right half of the neck, trunk, and lower leg as depicted previously.6,7 The neck ROM (flexion and augmentation) was estimated with the subject in a prostrate situation with the head and neck projecting over the finish of a seat, with the shoulders contacting the edge of the seat and arms along the edge. The flexometer was appended to the right half of the head and over the ear. The subject was first taught to raise and flex the head advances to a situation as close to the chest and afterward to expand the head in reverse beyond what many would consider possible. These positions were held for 3 s each time and the point was recorded to the closest degree. 

For the evaluation of trunk ROM (revolution), the subject lay in a recumbent situation on a seat with the knees together and raised over the hips with the legs held corresponding to the seat and body. The flexometer was secured around the center of the thighs. With the shoulders held down, the subject was approached to move the knees sideways beyond what many would consider possible, first to the left and afterward to the right. The ROM was recorded to the closest degree. 

The ROM of the lower leg (flexion and augmentation) was acquired with the subject sitting on the seat with knees straight and the legs projecting over the finish of the seat with the flexometer affixed to within the right foot first. The subject was told to initially broaden the right foot downwards as far conceivable and afterward to flex the right foot upwards towards the knee beyond what many would consider possible. The ROM was recorded to the closest degree. For the reversal and eversion ROM of the lower leg, the flexometer was affixed to the front of the shoe at the lower leg. The subject sat toward the finish of the seat with the knees looming over the seat. With lower legs got in position by the assessor's free hand, the subject was asked to first to turn the foot inwards quite far and afterward to turn the foot outwards beyond what many would consider possible. The ROM was then recorded to the closest degree.
