Nowadays, all sport in entire worlds need a preparation for performances such as jumping, acceleration, speed, agility and others which should involve in both long and short term training program. Long term preparation may include a well-developed fitness training program by coaches while for short term preparation should include warm-up (Khorasani, Mansour, Tabrizi and Yusof, 2010). One part of the warm up preparation includes stretching, which is often performed prior to physical exercises (Khorasani et al, 2010). There are many types of stretching techniques including static stretching, dynamic stretching, combined static and dynamic stretching, ballistic stretching and others (Khorasani et al, 2011).
Generally, stretching is used to enhance the range of motion (ROM) of a joint (Khorasani et al, 2013). Stretching and flexibility training have been very common among the athletic population, making up a large part of training programs as well as pre-event warm up activities for athletes. Flexibility refers to the musculotendinous unit’s ability to elongate with the application of a stretching force, determining the range of motion of a joint. Therefore, the act of stretching can be defined as movement applied by an external or internal force in order to increase muscle flexibility and/or joint range of motion (Oakley, 2017). It has been used by athletics, coach and athletic trainers that increasing flexibility which important aspect of physical fitness, leading to an increase in sport performance and as well as reducing the risk of injury.

Apart from that, agility is consists of several components. They are acceleration, braking, and change of direction. Sporting events involve various modes of movement. In athletic events such as soccer, football, basketball and racquet sports, the athlete sprints, stops and changes direction rapidly. A mere tenth of a second can mean the difference in winning or losing. Troumbley (2010) defined agility as “The ability of the body or body parts to explosively brake, change direction, and accelerate again rapidly under control.
” Agility and power activities use stored energy from the stretch-shortening cycle. Soccer is a sport with a wide range of movement intensities which means that some moments of the game are relatively relaxed and progress slowly, whereas other moments of play demands a maximal bursts of intense exercise. Running, sprinting and cutting is high intensity movements and jogging, walking and standing is a low intensity movements which that occur in varying lengths and intensities in soccer. The skill level, style of play, tactical strategies, playing position and the physical capacity of the individual players on both teams all have some impact on interval work rate of soccer matches (Orenduff, 2010). There are demands imposed on soccer players in terms of fitness readiness requirements to produce power, explosiveness, speed, agility, balance, stability, flexibility and endurance (Dragijsky, 2017).
