Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ratio of angular displacement of lumbar spine and hip joint | 1 week after enrolled | Angular displacement of lumbar spine divided by angular displacement of hip joint |
| Bat-swing velocity | 1 week after enrolled | Maximal bat swing velocity during baseball batting |
| Ratio of angular displacement of thoracic spine and lumbar spine | 1 week after enrolled | Angular displacement of thoracic spine divided by angular displacement of lumbar spine |
| Timing of maximal angular velocity of hip joint | 1 week after enrolled | The time point where the hip joint reaches its maximal angular velocity over the batting phase |
| Timing of maximal angular velocity of lumbar joint | 1 week after enrolled | The time point where the lumbar joint reaches its maximal angular velocity over the batting phase |
| Timing of maximal angular velocity of thoracic joint | 1 week after enrolled | The time point where the thoracic joint reaches its maximal angular velocity over the batting phase |
