About

The purpose of the study is to investigate the acute effects of static stretching on the shoulder joint position sense of overhead athletes.

Full description

A crossover randomized controlled trial will be conducted with 17 overhead athletes (9 males and 8 females). All of them will perform the 3 study conditions in random order: a control (5-minute rest), and static stretching of 30 or 90 seconds of muscles around the shoulder. The shoulder joint position sense will be assessed before and immediately after these conditions, and tested by active repositioning for the range of 110º of flexion, with a video camera. Absolute, relative and variable angular errors will be calculated.

17 participants in 3 patient groups

Control Condition
No Intervention group
Description:
5-minute rest.
Static Stretching of 30 seconds Condition
Active Comparator group
Description:
Static stretching of 30 seconds of muscles around the shoulder of the dominant upper limb: Shoulder extension - shoulder extension with the hand resting on a door; Doorway stretch - horizontal abduction with the shoulder in 90º of abduction, the elbow in 90º of flexion and the forearm leaning against a door; Shoulder flexion - arms above the head against a wall; Cross-body stretch - maximal horizontal adduction of the arm, with the opposite hand holding the stretch; Overhead triceps - arm above the head and elbow flexed, with the other hand pulling the elbow; Internal Rotation 90° stretch - with the shoulder at 90º of flexion and the elbow at 90º of flexion, the opposite hand and forearm forces the internal rotation.

Other: Static Stretching
Static Stretching of 90 seconds Condition
Active Comparator group
Description:
Static stretching of 90 seconds of muscles around the shoulder of the dominant upper limb: Shoulder extension - shoulder extension with the hand resting on a door; Doorway stretch - horizontal abduction with the shoulder in 90º of abduction, the elbow in 90º of flexion and the forearm leaning against a door; Shoulder flexion - arms above the head against a wall; Cross-body stretch - maximal horizontal adduction of the arm, with the opposite hand holding the stretch; Overhead triceps - arm above the head and elbow flexed, with the other hand pulling the elbow; Internal Rotation 90° stretch - with the shoulder at 90º of flexion and the elbow at 90º of flexion, the opposite hand and forearm forces the internal rotation.
