Relationship between functional movement screen and athletic and karate performance in adolescents

Purpose. The tests of athletic and functional performance are widely used to assess physical ability and set performance goals. The aim of this study was to evaluate the relationship between functional movement and physical and karate-specific performance in adolescents. Methods. Karate technique, athletic performance, and Functional Movement Screen (FMSTM) were evaluated in 20 karateka aged 10-15 years (age: 12.2 } 1.9 years, height: 155.5 } 16.5 cm, weight: 48.6 } 19.5 kg). Correlation analysis determined the association between the various tests, and stepwise linear regression established performance prediction models. Results. Only individual FMSTM tests of deep squat, hurdle step, and push-up significantly correlated with gedan barai/ jaku zuki (r = 0.40, r = -0.61, r = -0.59, respectively) and the triangle step (deep squat: R = 0.43, push-up: R = -0.56). Muscular endurance, power, and agility showed a significant (p < 0.05) correlation with karate side-step and gedan barai/jaku zuki. The participants' body mass and muscle endurance were good predictors of mawashi geri (r2 = 0.51, p < 0.05), while body mass was a strong indicator of gedan barai/jaku zuki (r2 = 0.46, p < 0.05) and muscle endurance was a leading predictor of gedan barai (r2 = 0.34, p < 0.05). Conclusions. A combination of functional and athletic tests may be used to assess young athletes' predisposition to karate. The training focus in young karateka should be on developing fundamental movement capacity along with fundamental sport-specific skills to allow the young athlete's natural physical development.
