AB  - This study aimed to examine the relationship between knee valgus in the frontal 
      plane projection angle (FPPA) during single-leg squat (SLS), single-leg landing 
      (SLL), and other selected clinical tests in young athletes. Forty-three young 
      healthy elite football players (age: 13.2 (1.7) years) that were regularly 
      training in a local sports club participated in the study. The FPPA was assessed 
      using 2D video analysis. The screening tests included the passive single-leg 
      raise (PSLR), hip external and internal rotation (hip ER and IR), sit and reach 
      test, weight-bearing lunge test (WBLT), modified star excursion balance test 
      (mSEBT), countermovement jump (CMJ), single-leg hop for distance (SLHD), and age 
      peak height velocity (APHV). There was a significant positive relationship 
      between the knee valgus angles in the SLS test and the sit and reach test (r = 
      0.34) and a negative relationship with the hip ER ROM (r = -0.34) (p < 0.05). The 
      knee valgus angles in the SLL were negatively associated with the hip IR (r = 
      -0.32) and ER ROM (r = -0.34) and positive associated with the WBLT (r = 0.35) 
      and sit and reach test (r = 0.33) (p < 0.05). Linear regression analysis showed 
      that the results of the hip ER ROM and sit and reach tests were independent 
      predictors of the FPPA in the SLS test (r2 = 0.11, p = 0.03 and r2 = 0.12, p = 
      0.02, respectively). The conducted study showed that individuals with more hip 
      range of motion, more spine flexion extensibility, and less ankle dorsiflexion 
      ROM may be more likely to experience high degrees of knee valgus in FPPA.
