Introduction: it has been shown that in professional soccer players the use of tests and measurements for the analysis of neuromuscular strength and fatigue has significant effects in the identification of abnormalities as a risk factor for the onset of muscle injuries. In the literature it has been shown that the isometric strength test of the posterior chain (IPC-F) performed on force plates at 90° of the hip and knee has sensitivity indices in the peaks of relative strength, neuromuscular fatigue and effective recovery as an essential analysis element in high performance soccer players.
Methodology: descriptive study in 31 professional soccer players of the Colombian league (Age 19 ± 13 years; Height 170 ± 14 cm; weight 65 ± 12 kg) where strength measurement in Newton was performed with the IPC-F 90 ° test using the ForceDecks device from the company VALD Performance.
Results: statistical values were obtained for the total posterior chain IPC-F template on the left side, averaging 73N±16N with a range between 50N and 102N, and for the right side, averaging 76N±18N with a range between 45N and 124N with an asymmetry less than 10%.
Conclusions: the hamstring strength profile in professional soccer players allows the generation of statistical data related to biomechanical variables of movement involved in performance, such as force production rate, maximum peak force, velocity, and torque. The IPC-F test is a standardized test for the evaluation of isometric hamstring strength.
