Resumen. El propósito de la presente investigación fue doble: 1) Comparar la actividad muscular de la cadera y el muslo de los futbolistas profesionales cuando realizan sentadillas isométricas con y sin contracción controlada de la cadera; 2) Determinar las relaciones musculares que tienen lugar durante estas modalidades de ejecución del ejercicio. Metodología: 11 jugadores de fútbol profesionales sanos, realizaron al azar tres modalidades de sentadilla isométrica con una flexión de rodilla de 60 °: sentadilla convencional (SQ), sentadilla con contracción de abducción de cadera (SQ-ABD) y sentadilla con contracción de aducción de cadera (SQ-ADD), controladas al 70% de 1 repetición máxima. La actividad del glúteo medio (GM), el tensor de la fascia lata (TFL), el vasto medial (VM), el vasto lateral (VL), el semitendinoso (ST) y el bíceps femoral (BF) se obtuvo mediante electromiografía de superficie. Se analizaron las relaciones de los músculos de la cadera (GM/TFL), cuádriceps (VM / VL), isquiotibiales (ST/BF) e isquiotibiales/cuádriceps (H/Q). Resultados: GM aumenta en SQ-ABD y SQ-ADD en comparación con SQ (p<.01). Los músculos TFL, VL, SM y BF tienen una actividad significativamente mayor en SQ-ADD en comparación con SQ (p<.05). Los músculos VL, VM y BF aumentan significativamente su actividad en SQ-ADD en comparación con SQ-ABD (p <.05). GM/TFL, VM/VL y ST/BF no muestran diferencias significativas entre los tres métodos de sentadilla isométrica. La relación H/Q fue mayor en SQ-ABD y SQ-ADD en comparación con SQ (p<.01). Conclusión: La sentadilla con contracción de aducción de cadera de manera controlada aumenta la actividad muscular de la cadera y el muslo. La realización de esta maniobra combinada puede tener beneficios en el entrenamiento deportivo y la rehabilitación porque aumenta la relación H / Q de los jugadores de fútbol.

Abstract. The purpose of the present investigation was twofold 1) To compare the hip and thigh muscular activity of professional soccer players when performing the isometric squat with and without controlled hip contraction; 2) To determine the muscular relationships that take place during these methods of execution of the exercise. Methods: 11 healthy male professional soccer players, randomly performed three modalities of isometric squat at a 60° knee flexion: conventional squat (SQ), squat with hip abduction contraction (SQ-ABD) and squat with hip adduction contraction (SQ-ADD), controlled at 70% of 1 maximum repetition. The activity of the gluteus medius (GM), tensor fasciae latae (TFL), vastus medialis (VM), vastus lateralis (VL), semitendinosus (ST) and biceps femoris (BF) was obtained through surface electromyography. Hip (GM/TFL), quadriceps (VM/VL) hamstrings (ST/BF), and hamstrings/quadriceps (H/Q) ratios were analyzed. Results: GM increases in SQ-ABD and SQ-ADD compared to SQ (p<.01). The TFL, VL, SM and BF muscles have significantly higher activity in SQ-ADD compared to SQ (p<.05). The VL, VM and BF muscles significantly increase their activity in SQ-ADD compared to SQ-ABD (p <0.05). GM/TFL, VM/VL and ST/BF do not show significant differences between the three isometric squat methods. The H/Q ratio was higher in SQ-ABD and SQ-ADD compared to SQ (p<.01). Conclusion: The squat with hip adduction contraction in a controlled manner increases the muscular activity of the hip and thigh. Performing this combined maneuver can have benefits in sports training and rehabilitation because it increases the H/Q ratio of soccer players.
