Narrative objectives1

There are two types of stretching: static stretching and dynamic stretching. Static stretching continuously stretches the muscles, making the stretch reflex less likely to occur. This property is recognized as effective in improving soft tissue extensibility and recovery from fatigue. Self-stretching is a convenient means of daily life, and the Cross Body Stretch (hereafter CS method) and Sleeper Stretch (hereafter SS method) are used in overhead sports as a form of self-stretching for PST. Previous studies have shown that both CS and SS are effective in improving the range of motion of internal rotation of the shoulder joint, and some have compared CS and SS and found CS to be more effective in improving the range of motion of internal rotation of the shoulder joint. However, there are few reports that have verified the effectiveness of the CS method on elementary and junior high school students, and the effectiveness of the CS method remains unclear at this age group, when pitching disorders are most important. Therefore, this study examines the effectiveness of the CS and SS stretching methods on elementary and junior high school students.
