The traditional thoughts on improving vertical is to do a lot of plyometric training:
- Box Jumps
- Hurdle Jumps
- Bounding
I took a different approach and went into our weight area to improve remedial strength:
- Hang Cleans high pulls
- Hang Cleans
- Front Squats
- Back Squats
I wanted to improve the girl's leg strength as well as teach them the proper way to recruit muscles for jumping. Most female athletes go quads, hamstrings, glutes, then calves. The better pattern is glutes, hamstring, quads, then calves thus utilizing our larger muscle groups first resulting in an increase power output while minimizing the risk to an ACL tear via an overactive quadriceps muscle (every time your quad contracts it stretches and stresses the ACL).
My auxiliary training then incorporated a lot of plyometric type training:
- Vertimax
- Hurdle hops (single leg)
- Single leg box squats
- Approach jumps
Over a four week period (8 sessions) we saw an average increase in approach reach of 1.5" for the 18-1 team and 2" for the 16-2 team with one girl on each team even had a 3" improvement! I still have to talk to many volleyball moms and dads as to why their girls are lifting to help them jump and many don't totally understand but slowly I am winning them over. With this type of result there really isn't much room for argument.
