Lumbopelvic Control in Baseball Batting

Baseball batting is important to winning the games. Baseball batting is achieved by proximal-to-distal sequencing of body movements and controlled by the neuromuscular system. Poor lumbopelvic control could influence production and transfer of energy in the kinetic chain. This study aims to investigate the impact of lumbopelvic control in hitting mechanics and bat swing velocity in high school baseball players.

No intervention / Compare the difference in batting mechanics and bat-swing velocity in baseball players with good and poor lumbopelvic control

Primary outcomes

  1. Ratio of angular displacement of lumbar spine and hip joint

    Time frame: 1 week after enrolled

    Angular displacement of lumbar spine divided by angular displacement of hip joint

  2. Bat-swing velocity

    Time frame: 1 week after enrolled

    Maximal bat swing velocity during baseball batting

  3. Ratio of angular displacement of thoracic spine and lumbar spine

    Time frame: 1 week after enrolled

    Angular displacement of thoracic spine divided by angular displacement of lumbar spine

  4. Timing of maximal angular velocity of hip joint

    Time frame: 1 week after enrolled

    The time point where the hip joint reaches its maximal angular velocity over the batting phase

  5. Timing of maximal angular velocity of lumbar joint

    Time frame: 1 week after enrolled

    The time point where the lumbar joint reaches its maximal angular velocity over the batting phase

  6. Timing of maximal angular velocity of thoracic joint

    Time frame: 1 week after enrolled

    The time point where the thoracic joint reaches its maximal angular velocity over the batting phase
