Immediate effects of neuromuscular electrical stimulation on drop jump performance measured through kinematic analysis

This study aimed to investigate the immediate effects of neuromuscular electrical stimulation (NMES) on high-platform drop jump performance through kinematic analysis. Thirty healthy male physical education students were randomly recruited (15 in the experimental group and 15 in the control group). The experimental group received a 20-min NMES intervention before performing the drop jump test. The Kwon3D motion analysis system was used for data processing, and the drop jump process was divided into five key phases for kinematic parameter analysis. The results showed that the jump height of the experimental group was significantly higher than that of the control group (p < .05). Additionally, during the explosive rising phase, the experimental group demonstrated significantly greater center of gravity velocity, hip joint angle, and velocities of the thigh, calf, and sole compared to the control group (p < .05). The findings indicate that NMES effectively induces the post-activation potentiation (PAP) effect, enhancing lower-limb explosive power and overall athletic performance. This study provides scientific evidence for the potential application of NMES as a training strategy and recommends further exploration of its long-term effects and impact on different populations.
