Pengaruh Core Stability Exercise Terhadap Peningkatan Keseimbangan Dinamis Pada Pemain Sepak Bola

Balance is an ability to maintain and control the position of the body when stationary or moving. Balance is really needed by every player in the game of football, especially when making fast-paced movements such as one when dribbling, while avoiding and contacting opponents. If the player does not have a good balance, then when making a move that takes place quickly will have difficulty in controlling the movement, so that it could result in the risk of falling and injury so that the player's performance decreases. Provision of core stability exercise aims to strengthen core muscles to maintain position when controlling the ball and when making rapid movements through postural control. The method used is a quasi-experimental approach with a pre and post research design with a control group. Respondents were 20 PSB junior Al Wathonni players who were divided into 2 groups by purposive sampling. The results of research with statistical calculations show the value of sig. p = 0.00 in the treatment group given core stability exercise and sig. p = 0.327 in the control group. The conclusion from the statistical result is that there is an effect of providing core stability exercise on increasing dynamic balance in soccer players
