Objectives
Narrative objectives1
This study aimed to determine the comparative effectiveness of cross-body and sleeper stretching in young baseball players and provide evidence to guide clinical practice. We hypothesized that a combined regimen of cross-body and sleeper stretching would improve shoulder internal rotation, horizontal adduction, and total rotational ROM more than cross-body stretching alone.

Results
Significant differences in within-group comparisons before and after the intervention were observed in internal rotation for both groups, total range of motion in the Combined intervention group, and horizontal adduction for both groups. On the other hand, no significant differences were found in external rotation or the total range of motion in the Single intervention group.

Baseline Characteristics
This randomized controlled trial was designed to evaluate the intervention effects of two types of stretching on youth and adolescent baseball pitchers. Participant selection and data collection were conducted at the baseball field where the players practiced, prior to the start of practice sessions, in July 2023. Both the participants and their guardians were provided with detailed written and verbal explanations regarding the purpose, methods, and potential risks of the study. Consent forms were obtained after ensuring that the participants' rights were adequately explained and protected.
