Abstract

The aim of this study was to analyze the Sticking Re-gion at submaximal (70%, 80%, 90% until failure) and maximal (1RM) loads in the concentric phase during bench press. Eleven male individuals participated in the study (age: 22.73 ± 2.57 years, body mass: 80.2 ± 6.9 kg, height: 179.6 ± 7.4 cm, 1RM: 94.55 ± 11.56 kg) with at least two years of bench press training experience. In our sample, The Sticking Region could only be obser-ved with 90% and 100% 1RM loads. The velocity results showed significant differences in 1RM (p ≤ 0.001) and in 90% (p = 0.014) during the three phases (Pre-Sticking, Sticking Region and Post-Sticking zones). Differences in the electromyographic activity of the triceps brachii were found only between the Pre-StickingRegion and the Sticking Region and between the Pre-Sticking Re-gion and the Post-StickingRegion at 1RM. The activity between the Sticking Region and Post-StickingRegionat 90% and 1RM did not differ significantly. This stu-dy suggests that the Sticking Region is more visible with maximum loads (1RM) due to a weak mechanical position
El objeto de este estudio fue analizar la Sticking Region en las cargas submáximas (70%, 80%, 90% hasta el fallo) y máximas (1RM) durante la fase concéntrica en press de banca. Para este estudio, fueron once los participantes (edad: 22,73 ± 2,57 años; masa corporal: 80,2 ± 6,9 kg; altura: 179,6 ± 7,4 cm; 1RM: 94,55 ± 11,56 kg) con al menos dos años de experiencia en press de banca. En nuestra muestra, la Sticking Region solo pudo ser observada en las cargas del 90% y 100% 1RM. Los resultados de velocidad mostraron diferencias estadísticamente significativas en 1RM (p ≤ 0,001) y en 90% (p = 0,014) durante las tres fases (Pre-Sticking, Sticking Region y Post-Sticking). Observamos diferencias en la actividad electromiográfica del tríceps entre las regiones Pre-Sticking y Sticking, así como entre la region Pre-Sticking y Post-Sticking en la carga de 1RM. La actividad entre la Sticking Region y Post-Sticking Region, en las cargas del 90% y 100% no mostró diferencias estadísticamente significativas. Este estudio sugiere que la Sticking Region es más visible en cargas máximas (1RM) debido a una baja posición mecánica
