Objective: The hamstring muscles in soccer are the region with the highest percentage of muscle injuries, due to numerous risk factors, including isometric strength levels. In this way, the aim is to know and establish a strength profile in this musculature in elite Asian players. Method: During the first part of the preseason, an elite soccer team (N=46 players) belonging to the AFC Champions League underwent isometric hamstring strength assessment at 30º and 90º, using a dynamometry device ( ForceFrame ®, Valdperformace). Results: Among the results obtained, an average profile in Isometric Force (N) at 30º of 268 N (+- 46.4), an average profile of Isometric Force (N) at 90º of 206 N (+- 42.1) is observed. ), a bilateral asymmetry (%) at 30º of 2.23% (+- 12.2) and a bilateral asymmetry (%) at 90º of 6.46% (+- 15.9). Regarding the correlation between measured variables, a moderate positive correlation (0.732, p=0,001) is observed between the average of bilateral Isometric Strength (N) at 30º and at 90º. Conclusions: In light of the results obtained, it is observed that the players in the present sample present higher levels of isometric strength at 30º than at 90º, nevertheless presenting higher % of bilateral asymmetry at 90º compared to 30º.
