EFFECTS OF LADDER TRAINING ON THE MOBILITY OF VOLLEYBALL PLAYERS

The step movement in volleyball is a fundamental skill that volleyball players must master, being the basis of the support of all other techniques of this sport.

Objective:

Explore the effect of ladder training on the mobility of high school volleyball players.

Methods:

Twenty high school male volleyball players aged 16-17 were selected as experimental volunteers. Randomly divided into experimental and control groups, 10 individuals in each group received a training intervention for 8 weeks, with ladder training added to the experimental group.

Results:

Both pieces of training resulted showed positive effects on the improvement of movement ability and speed and could effectively improve the athletes’ movement speed ability.

Conclusion:

Through systematic ladder training, the excitatory conduction time in the reflex arc of athletes was significantly reduced, leading to a faster response to various signal stimuli, bringing the athletes’ central nervous system to a state more prepared for sports practice. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
