Effectiveness of Basketball Pre-injury Attack Program to Reduce the Susceptibility of Injury in Youth Basketball Players: a Randomized Controlled Trial

Basketball is an impact, coordination-opposition sport with continuous contact among players and it is considered a sport of medium-high injury incidence. Players are force to have a physical condition appropriate to their practice and the demand to which they must respond due to the intensity of the efforts this sport requires. In order to achieve this, it is necessary to establish an evaluation protocol that allows the detection of functional deficiencies, to guide and conduct in a specific and early way every moment of players' health and growth. The purpose of this study is to design, apply and analyze the effectiveness of a specific and individualized therapeutic exercise program (Basketball Pre-injury Attack) based on the approach of the functional deficiencies detected by the Basketball Injury Defense, to reduce the susceptibility to injury of youth basketball players (U14 - U17).

The aim of this study is to design, apply and analyze the effectiveness of a specific and individualized therapeutic exercise program (Basketball Pre-injury Attack) based on the approach of functional deficiencies detected by the Basketball Injury Defense, to reduce the susceptibility to injury of training federated basketball players. The specific objectives are: To improve the deficiencies detected in mobility, stability, symmetry and jumping/landing technique of basketball players in training categories (U14, U16 and U17). To structure and determine the contents of a specific and individualized therapeutic exercise program (Basketball Preinjury Attack) designed to improve the functional deficiencies of mobility, stability, symmetry and jumping/landing technique of training basketball players based on current scientific evidence. To analyze whether adherence to the program is achieved by raising players' awareness of the importance and benefits of performing the exercises with correct technique. To assess whether a decrease in the susceptibility to injury of training federated basketball players is achieved. For this purpose, an experimental study was conducted as a single-blind, randomized, cluster-controlled clinical trial during the months of June 2019 to February 2020 (9 months). For the development of the methodology of this study, the guidelines of the CONSORT (Consolidated Standards of Reporting Trials) Statement were followed.

The study was blinded to the investigators who performed both recruitment and assessments. In this way, detection bias could be controlled. It was not possible to perform a double-blind study, since it was a physical intervention and the player knew that he/she was undergoing an intervention program.

The intervention group carried out a program for 24 weeks. The participant had to perform the program 3 days per week for 12-15' each day (training days with the team, prior to group activation).

The intervention had a total duration of 24 weeks, with 3 sessions per week (before starting training) with a total duration of 12 to 15 minutes per session. Each session consisted of 8 exercises with a load of 2 to 3 series between 6 and 12 repetitions; and with a rest at the end of each series of <60 seconds.

The Weight-bearing Lunge Test measured with the Leg Motion® system (Check Your Motion, Albacete) was used. Ankle dorsiflexion was recorded in centimeters.

The Hurdle Step Test measured with the Leg Motion® system (Check Your Motion, Albacete) was used. A frontal and sagittal view was recorded with two filming devices so that the results could be analyzed later. Impairment was considered in those cases in which the subject was not able to step the foot over the rope during the hurdle step or if he/she performed adduction, internal or external rotation of the hip, and lost alignment between the hip, knee and ankle.

The Single Leg Squat Test was used and the criteria established by Perrot were used: it was considered stable if the foot remained in neutral position during the movement; and unstable if excessive pronation of the foot was evident during the movement or external rotation of the leg. To analyze the results, a frontal and sagittal view was recorded with two filming devices.

The Single Leg Squat Test was used. The evaluator recorded a frontal and sagittal view with two filming devices. The knee was considered to be aligned if the patella was over the second toe.

It was evaluated qualitatively with the Single Leg Squat Test and the Hurdle Step Test. To analyze the results, a frontal and sagittal view was recorded with two filming devices and the criteria established by Perrot were used. It was considered stable if there was minimal movement in all three planes, the pelvic girdle was aligned and there was no evidence of excessive anteroposterior tilt and/or trunk rotation. It was considered unstable if these criteria were not met.

It was analyzed qualitatively with the Single Leg Squat Test. The test was recorded with two filming devices (frontal and sagittal) and the criteria established by Perrot and Crossley were used. For this purpose, the deviation of the trunk with respect to the center of gravity was observed. It was considered stable if there was minimal translation of the center of mass, i.e., no lateral flexion/tilt, rotation or trunk flexion/extension.

It was analyzed with de Single Hop for distance Test. Ankle stability at landing, dynamic knee valgus, lumbopelvic stability and dynamic postural stability were analyzed.

From the distance obtained in the Single Hop for distance Test, the Symmetry Index was calculated using the formula: (Distance dominant limb/Distance non-dominant limb)*100.
