The main objective was to determine the strength and power values in a professional Major League Soccer (MLS) team. Twenty-two professional football players from an MLS club, excluding goalkeepers, participated. Six assessments were conducted, including three pre- and three post-tests, assessing eccentric hamstring strength in the Nordic curl using the NordBord, maximal isometric strength in hip adduction-abduction with ForceFrame, and lower body power with CMJ in ForceDecks. The strength and power values established with the Pre and Post assessments show a CMJ height of 43.96 ± 3.92cm, in Nordic curl 382.46±67.79N-I and 370.66±65.84N-D, in hip adduction 414.79±73.86N-I and 424.02±71.88N (R), and in hip abduction 411.93±60.19N-I and 420.77±60.54N-R. The comparison between Pre and Post evaluations showed statistically lower values (p<0.05) in the Nordic Curl, hip adduction and abduction, while the CMJ showed no significant changes (p=0.056). On the contrary, after the transitional period only the CMJ showed lower values (p<0.05) compared to the Nordic Curl, and hip adduction and abduction (p˃0.05). The data studied show lower post-session strength values, except for power expressed in CMJ height. After the transitional period, hamstring and hip strength (ABD-ADD) did not show significant changes, but CMJ height did.
