The aim of this study was to compare FPPA between three landing tasks and determine the reliability of FPPA in 15 competitive female gymnasts (age 13.5 ± 2.07 years). Reliability of FPPA was highest in the drop landing task, with no learning effect present. The backaway task showed the greatest FFPA (right: 26.75 ± 9.57°; left: 19.67 ± 9.03°), which was greater than the drop landing task (right: 19.07 ± 7.42°; left: 12.18 ± 4.83°). Individuals involved in training young female gymnasts are encouraged to screen for injury risk using FPPA during the drop landing task.

The high rate of ACL injury has led to the need for large-scale injury risk screening to aid in prevention. Cost and time alternatives to three-dimensional assessments of knee injury risk factors are necessary for largescale, clinical use. The purpose of this study was to determine the expert versus novice interrater reliability and test-retest reliability of the frontal plane projection angle (FPPA) during the single-leg squat (SLS) test. Excellent interrater reliability was demonstrated for session 1 and session 2. Excellent intrarater (i.e., test-retest) reliability was demonstrated for both the novice and expert. The minimal training requirements and excellent reliability of the FPPA during the SLS test make it a key screening tool for large-scale assessment of injury risk.

Positive Results

Closed kinetic chain exercises have been employed in rehabilitation and muscle strengthening programs, such as squatting. During the movement of the squat dynamic valgus, a change that affects all kinematics of the lower limb, tends to become exacerbated, necessitating adaptations in order to minimize the biomechanical disorder. Although studies have shown the effectiveness of squatting exercises, there is a lack of evidence to demonstrate, comparatively, the effectiveness of different adaptations in the decrease of dynamic valgus. The objective of the study was to evaluate to identify the efficacy of different adaptations in squatting exercise in the reduction of dynamic valgus. Therefore, study volunteers (n = 30) performed three types of squats: free squatting, squatting with elastic band and squatting with verbal command. The dynamic valgus wasmeasured by the knee frontal plane projection angle during the squatting movements, through captured images and analyzed by the software Tracker and ImageJ. Despite more cases in women, in both sexes, free squatting presented greater cases of medicalization of the knee than in comparison to the other two adaptations. Although both squat adaptations presented positive results, only squatting with verbal command showed a significant reduction of the dynamic valgus pointing out that this is the best adaptation treated.   Keywords: Genu Valgum. Exercise Therapy. Motor Activity.   Resumo Exercícios de cadeia cinética fechada vêm sendo empregados em programas de reabilitação e fortalecimento muscular, como é o caso do agachamento. Durante o movimento de agachamento o valgo dinâmico, alteração que afeta toda cinemática do membro inferior, tende a se tornar exacerbado, sendo necessárias adaptações com o intuito de minimizar o distúrbio biomecânico. Embora estudos tenham mostrado a eficácia dos exercícios de agachamento, faltam evidências que demonstrem, comparativamente, a efetividade de diferentes adaptações na minimização do valgo dinâmico. O objetivo do estudo foi identificar a eficácia de diferentes adaptações na execução do exercício de agachamento na redução do valgo dinâmico. Para tanto, os voluntários do estudo (n=30) três tipos de agachamentos: agachamento livre, agachamento com banda elástica e agachamento com comando verbal. O valgo dinâmico foi mensurado mediante o ângulo de projeção no plano frontal do joelho durante os movimentos de agachamento, através de imagens capturadas e posteriormente analisadas pelos softwares Tracker e ImageJ. Apesar de mais casos em mulheres, em ambos os sexos, o agachamento livre apresentou maiores casos de medicalização do joelho do que nas outras duas adaptações. Embora ambas adaptações de agachamento apresentaram resultados positivos, apenas o agachamento com comando verbal apresentou redução significativa do valgo dinâmico, apontando ser esta a melhor adaptação tratada.
