Effects of an Isometric Training Session on Post-exercise Neuromuscular Function When Compared to Dynamic Strength Training

July 29, 2025 updated by: Filipe Silvano Pinto Maia, University of Maia

Effects of an Isometric Training Session on Post-exercise Neuromuscular Function When Compared to a Dynamic Strength Training Session in Youth Soccer Players

The existing literature shows that maximum strength can be improved through both dynamic and isometric strength training. However, there is a perception that dynamic training has a negative effect on short-term neuromuscular performance in soccer players. Hence, the aim of this study was to compare the neuromuscular impairment after isometric and dynamic training sessions in young soccer players.
