The experimental group followed a program that included three scapulothoracic stabilization exercises and three for glenohumeral stability, while subjects in the control group only performed the glenohumeral stabilization exercises. Two weekly sessions were carried out over a period of 6 weeks, and each session lasted 30 minutes. The intervention was conducted before starting the training session, to avoid muscle fatigue.

The experimental group followed a program that included three scapulothoracic stabilization exercises and three for glenohumeral stability, while subjects in the control group only performed the glenohumeral stabilization exercises. Two weekly sessions were carried out over a period of 6 weeks, and each session lasted 30 minutes. The intervention was conducted before starting the training session, to avoid muscle fatigue. Three series, with 10 repetitions of each exercise, with one minute rest between series.

The investigators used the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST). This scale evaluates the number of upper limb movements the subject is able to make during 15 seconds. A higher score represents better shoulder stability.

Bouldering test, replicating the demands of a competition. The test was carried out on a 4-meter-high wall and with a 20 degree inclination, having a route with 15 climbing holds: 3 small, 7 medium and 5 large. A start hold and an end hold were clearly identified. The climber had 5 minutes to visualize the route, in a familiarization process often used in competitions. Before the test participants was told that they should be as efficient as possible in their movements. The time taken by the climber to complete the route was recorded, and the number of grips for the route.
