Abstract

Purpose
This study sought to identify the effects of coordinative locomotor training (CLT) using elastic bands on the flexibility and body alignment of right-handed baseball players in elementary school.
Methods
The subjects were 20 instructed right-handed baseball players in elementary school. They were classified into the experimental group with 10 players (n = 10) to be given coordinative locomotor training using elastic bands and the control group with 10 players (n = 10). Flexibility was measured by the sit and reach exercise. Body alignment was measured using formetric 4D method to measure the trunk imbalance angle (TI), trunk torsion angle (TT), pelvic tilt angle (PTi), pelvic torsion angle (PTo), pelvic rotation angle (PR), kyphotic angle (Ky), and lordotic angle (Lo).
Results
There was a significant increase in the flexibility within the experimental group (p < 0.05). after the intervention. There was also a significant increase in the difference between the experimental group and the control group (p < 0.05). There was a significant decrease in PR during body alignment in the experimental group after intervention (p < 0.05). An analysis of the differences between groups showed a significant decrease in the PR of the experimental group compared to the control group (p < 0.05).
Conclusion
These findings show that coordinative locomotor training using elastic bands would be effective for enhancing the flexibility and pelvic rotation of elementary school right-handed baseball players.
