LOWER LIMBS PERFORMANCE EVALUATION OF PROFESSIONAL VS.

YOUNG SOCCER PLAYERS

Evaluate lower limbs strength professional Vs. youth team;

Lateral and anterior-posterior muscular imbalances;

Correlate strength to jump performance.

• No lateral differences in quadriceps and hamstrings

peak

torque in both groups;

• Single limb jump correlated with quadriceps strength

(0,630 to 0,724 , p< 0,05 ).

Discussion

• Laterality does not reflect strength (Pietrosimone 2012);• Quadriceps strength influence jump performance (Wisloff, 2004);• Hamstrings should be reinforced in professional team (Delextrat, 2011).
