Guys like ariza just use this stuff cuz if they don't they'd be out of a job.
Plyometrics
Plyometrics are highly controversial. Most of the support for plyometrics is based upon anecdotal evidence. There is little unbiased scientific evidence that definitively proves plyometrics are productive. In reality, a large number of research studies have concluded that plyometrics are no more effective than regular strength-training activities when it comes to improving speed, power and explosiveness. One plyometric guru even admits that the information about plyometrics is anecdotal and “methodologically weak.”
More importantly, the possibility of injury from plyometrics is positively enormous. A growing number of strength coaches have been questioning the safety of plyometrics. When performing plyometrics, the musculoskeletal system is exposed to repetitive trauma and high-impact forces. This extreme biomechanical loading places an inordinate amount of strain on the connective tissues of the lower body. The most common plyometric-related injuries are patellar tendinitis, stress fractures, shin splints and strains of the ankle and the knee. Compression fractures related to the use of plyometrics have also been reported. Other potential injuries include -- but aren’t limited to -- sprains, heel bruises, ruptured tendons and meniscal (cartilage) damage. It’s no surprise that many prominent orthopedic surgeons, physical therapists and athletic trainers view plyometrics as an injury waiting to happen.
In short, plyometrics have not been proven to be productive and carry an unreasonably high risk of injury.
