Agility Ladder Training Combined With Plyometric or Multidirectional Speed Drills: Short-Term Adaptations on Jump, Speed, and Change of Direction Performance in Young Female Volleyball Players

Agility ladder training programs combined with either plyometric or speed drills can improve change of direction performance in young female volleyball players but only the combination of agility ladder with multidirection speed drills is more effective than volleyball training per se. The small effectiveness of these protocols may be attributed to the short training period, or to the fact that training elements were combined in a single session. This hypothesis remains to be further investigated.
