Comparison of Hamstrings and Quadriceps Muscle Activation in Male and Female Professional Soccer Players

(1) Background: this study aimed to determine if there are differences in quadriceps and hamstring muscle activation professional male female soccer players. (2) Methods: was recorded by surface electromyography 27 players (19 8 female). The performed the Bulgarian squat lunge exercises. Vastus medialis, vastus lateralis, rectus femoris, semitendinosus, biceps femoris were muscles analyzed. (3) Results: statistical analysis of hamstring:quadriceps ratio showed no significant (p > 0.05). Significant found medialis:vastus lateralis for both exercise (t20 = 3.35; p 0.001; d 1.42) (t23 4.15; < 1.76). For intragroup muscular pattern exercises, higher 0.001) than lower medialis. No remoris, semitendinosus (4) Conclusions: Differences medial (vastus medialis: lateralis). Moreover, regarding intramuscular pattern, very consistent patterns have been found. In muscle: VM>VL>RF; ST>BF. These could be useful recovery process from an injury return their highest performance.
