In this post we mainly focus on plyometrics that are jumping movements. This is where the basketball player actually jumps up off the ground. The stored force or elastic energy is released in this phase propelling you up into the air. Concentric Contractions: This is when muscles are shortening while still producing force.It’s important to note that if this phase lasts too long some of the potential energy can be lost. The dynamic stabilization happens as the muscle rebounds from storing the energy to releasing it. Amortization Phase: This is the transition time between the eccentric and concentric contractions of the muscle.You can think of when basketball players bend at the knees before getting ready to spring up into the air. This is the loading, cocking or absorption phase. The stretching muscle stores potential energy in its elastic components. Eccentric Contractions: This is when the muscles are stretching and lengthening while still producing force.The three major segments including both types of muscle contractions that create the stretch-shortening cycle are: Force is produced on both sides of these contractions. These contractions are when the muscles are shortened or lengthened. Plyometrics are so effective at improving explosive movements because they take advantage of opposing muscle contractions. How do plyometrics improve explosive power? The world of fitness continues to evolve with people now referring to multiple explosive movements as plyometrics, even including exercises like pushups. In modern day fitness training, you will hear the word plyometrics being applied to multiple exercises not just the original jump training. Verkhoshansky to more varied plyometric exercises being used today. Plyometrics has since become an important aspect of many athlete’s training regimens, from the original shock method of Dr. From the early 1980’s Yessis continued to develop new methods of using the principles of jump training to enhance explosive power. Wilt later teamed up with Michael Yessis who had spent time in the Soviet Union and worked with Dr. Verkhoshansky tried many other exercises but he found the best results when using this depth jump to replicate the forces of landing and takeoff.įred Wilt saw this style and took notes of how athletes were jumping and skipping around. This all happened in a short time frame of. This created a forced eccentric contraction which was then converted immediately into a concentric contraction as the athlete would jump immediately after landing. This original “jump training” employed the use of the shock method where an athlete would drop down from a raised platform then upon hitting the ground would experience a “shock”. It was no coincidence that during this time frame the Soviet Bloc countries were crushing everyone in track and field events (they possibly had some extra help from some performance enhancers as well during this time). He published his findings on this new method of training in 1964.

He designed a series of exercises called “jump training” where athletes would complete multiple jump exercises to try to increase speed and explosiveness. The scientist leading the charge in this new training protocol was Dr. Plyometrics were first developed by scientists from the Soviet Bloc during the Cold War in the 1960s-1970s. Today you might hear people referring to plyometrics as simply, plyos. The word comes from the Greek words plio meaning more and metric meaning to measure. The word plyometrics was coined by Fred Wilt, a former US Olympic long-distance runner.
