Implication

Retrospective observational study examines exercise effects on trunk extension and pain in high school baseball players, indicating diverse responses.

Key Points

To investigate immediate changes in trunk extension angle and pain intensity following a structured exercise program for athletes with extension-type low back pain.
Analyzed data from 6,105 male high school baseball players reporting pain-related limitations.
Included 54 athletes with clinically diagnosed extension-type low back pain who underwent a five-exercise program.
Assessed trunk extension angle and pain intensity before and after each exercise.
Trunk extension angle increased from 60.7° to 78.4° after the exercise sequence.
Mean pain intensity decreased from 10.0 to 2.4.
Identified three response patterns indicating heterogeneity in functional responses after exercises.
