Brief Summary

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 evaluate and detect federated youth basketball players' (U12 - U17) neuromuscular deficiencies in mobility, stability and landing technique in static and dynamic situations to simulate all the most important actions of basketball demands.

Outcome Measures

Primary Outcomes (8)

• Ankle joint dorsiflexion

  Weight-bearing dorsiflexion test. Ankle dorsiflexion was evaluated through the LegMotion system (LegMotion, your Motion®, Albacete, Spain). Each player started with their hands on their hips, and put the assigned foot on the middle of the longitudinal line just behind the transversal line on the platform. The alternate foot was positioned off the platform with toes at the edge of the platform. Each trial consisted of flexing the ankle as much as possible without raising the heel of the assessed ankle trying to touch a marker, situated just behind the patella, with their knee. The distance achieved was recorded in centimeters. Three trials were allowed with each ankle (i.e., left and right) with 10 seconds of passive recovery between trials. The third value in each ankle was used in subsequent analysis of weight-bearing dorsiflexion.

  Through study completion, an average of 1 year

• Ankle stability

  Single Leg Balance Test. It was considered stable if the foot remained in neutral position during movement. However, if excessive pronation of the foot was evident during movement or external rotation of the leg/foot it was scored as unstable.

  Through study completion, an average of 1 year

• Dynamic lower extremity valgus

  Single Leg Squat Test. An aligned knee-ankle position was considered when the patella was aligned with the second toe. Five consecutive attempts were performed with each limb, and the correct alignment between the knee and the second toe in loading was assessed to analyze an excess of knee valgus.

  Through study completion, an average of 1 year

• Lumbopelvic stability

  Single Leg Squat Test. It was considered stable if there was minimal movement in all three planes and the sacroiliac joints were aligned. On the other hand, it was considered unstable if the sacroiliac joints were not aligned in the frontal plane or if there was evidence of anteroposterior tilt or rotation in the sagittal plane as well as anterior trunk flexion or increased lumbar lordosis.

  Through study completion, an average of 1 year

• Dynamic postural control

  Hurdle Step Test. For this purpose, the deviation of the trunk with respect to the center of gravity was observed. A smaller displacement or deviation implied a better postural stability.

  Through study completion, an average of 1 year

• Neuromuscular deficits during continuous tuck jumps

  Modified Tuck Jump Test. Lower extremity valgus at landing, Thighs do not reach parallel (peak of jump), Thighs not equal side-to-side during flight

  Through study completion, an average of 1 year

• Landing technique flaws

  Modified Tuck Jump Test. Foot placement not shoulder width apart, Foot placement not parallel (front to back), Foot contact timing not equal (Asymmetrical landing), Excessive landing contact noise.

  Through study completion, an average of 1 year

• Plyometric Technique

  Modified Tuck Jump Test. Pause between jumps, Technique declines prior 10 seconds, Does not land in same foot print (Consistent point of landing)

  Through study completion, an average of 1 year

Study Arms (1)

Youth basketball players who belonged to basketball developmental teams (U12, U14,U16,U17).

All participants completed the same ten-minute neuromuscular warm-up consisting of the following exercises: joint mobility exercises, dynamic stretching exercises, jumps, multidirectional displacements and changes of direction. Following, subjects were allowed three practice trials for each test. Consistent feedback was provided throughout to ensure proper technique. The performance of each test was recorded using two cameras (Iphone XS, Apple). To allow visible tracking of the different joints, participants were required to wear shorts with the hem at approximately mid-thigh. When scoring performance, each test was viewed in both planes (sagittal and frontal views).
