简要总结
Basketball is a team sport that requires specific motor skills to develop different technical-tactical actions. Within the specific movements, landings after a jump are very common and require optimal technical performance, good stability and symmetry. Alterations in these components have been linked to an increased risk of injury. The objective of the present study is to identify functional alterations in the jump / landing technique that basketball players present.
Cross-sectional study carried out from Septembre to Juny. The participants were basketball players aged 12 to 14 years. The main variables were: ankle stability, dynamic knee valgus, central stability, symmetry of the lower extremities. The tests used were: Abalakov Test, Single Hop Test for distance, Single-leg vertical countermovement jump test, Cross Over Hop test, One Leg Balance Test.

结局指标
主要结局
Symmetry
时间窗: 1 year
From the distance obtained in the Single Hop for distance Test, the Symmetry Index was calculated through the formula: (Distance dominant limb/Distance non-dominant limb)\*100.
Dynamic lower extremity valgus
时间窗: 1 year
It was evaluated with the Abalakov Test and the Single Hop test for distance. For this purpose, two filming devices were placed, one frontal and one lateral. For the detection of dynamic valgus at landing, the angle formed between the femur and the tibia was looked at. The results were subsequently analyzed with the recording obtained.
Ankle stability
时间窗: 1 year
The ability of the player to maintain the monopodal position throughout the test and at the same time perform the jumps continuously without compensating with small jumps to stabilize was evaluated with the Cross Over Hop test and Single Hop Test for distance. It was recorded with a frontal and lateral filming device. The results were subsequently analyzed.
Dynamic postural control
时间窗: 1 year
The Abalakov Test, Single Hop Test for distance and the Single-leg vertical countermovement jump test were used to observe the trunk alignment during the jump taking the hip and shoulder girdle as reference. For this purpose, two filming devices were placed in frontal and lateral positions. The results were subsequently analyzed with the recording obtained.
