Abstract


INTRODUCTION
Sport is a physical activity regulated formally and informally by competing against others or oneself to get pleasure or victory (Lumpkin et al., 2017). A person's sports involvement will automatically form character (Ali, 2015). Sports achievements have a high prestige value for a nation by giving rise to excellence in international competition.
Sepaktakraw is a sport carried out by kicking a ball over a barrier net or net played on a field the size of a badminton court (Sujae & Koh, 2015).
Sepaktakraw is included in the category of team sports or team sports. A sport consists of several interconnected individuals who work together to achieve a successful outcome (Duarte et al., 2015). In line with an opinion (Chen & Xiao, 2017), "There are several forms of Sepak Takraw, but the most popular is the "Regu" format, where opposing teams of 5 players, 3 on-court with two substitutes, line up against each other ".
According to (Putra et al., 2020), the game of takraw has several basic techniques that must be mastered, including soccer or ball control techniques. According to (Nusufi, 2014), in the game of takraw, good physical conditions are needed to carry out the basic techniques of the game.
In the sepak takraw, each team holds and manages the ball three times on the permitted body parts and kicks to score the winning goal (Udomtaku & Konharn, 2020). One occurs in the back serve movement, where the player must swing one of his legs over his head to kick the ball (Bhasavanija & Kuan, 2017).
According to (Sam, 2019), mastery of takraw skills is necessary, aiming for the game to run well. According to (Ibrahim et al., 2022), "Sepaktakraw players must have good soccer skills to perform defensive and attacking techniques in the game of takraw." Furthermore, the statement (Astra, 2017), "Sepak Takraw Playing Technique course, fundamental techniques," Each player in the takraw game must be able to handle and keep the ball in the air with good defense and attack.
Anthropometry pays attention to the relationship between the structure and function of the human body, especially in the context of movement (Eston, 2016). Same with (Ita, 2019), "The anthropometric structure is related to the measure of the athlete's ability to make movements related to the sports involved." Anthropometry is a term that describes body dimensions such as height, Weight, circumference, and folds (Tour & Bibiloni, 2019). Sports performance is influenced by factors seen from the physical aspect, including body height, body weight, sitting height, length of the upper and lower limbs, and body type (Furqon, 2016).
An essential part of talent scouting is anthropometry (Mylsidayu & Kurniawan, 2015). Anthropometric measurements are a series of quantitative measurements of muscle, bone, and adipose tissue to assess body composition (Casadei & Kiel, 2021). So anthropometry is closely related to body characteristics and sports achievements (Thirumagal, 2013 (Wahyuri, 2018). A player's success as a tekong or a player who serves is critical because points are earned by serving well, accurately, hard, and producing points for the team (Aji, 2017).
Exercise is essential in increasing the ability to function in the human body's organ systems to make it easier to perfect movements (Sukadiyanto, 2016). According to (Wijayanti et al., 2015), planning exercises must be directed, theoretical, future-oriented, and structured.
