Plyometrics

Plyometrics

The term "plyometrics" originated in 1975 when American track and field coach Fred Wilt coined the word by combining Greek roots. He derived it from the Greek words "plio" (meaning "more") and "metrics" (meaning "to measure"), essentially translating to "to increase the measurement" 

Etymology and Origins of Plyometrics

The word has fascinating linguistic roots:

  • Originally based on the Greek word "pleythyein", which means "to increase or augment" 

  • Technically combines "plio" (more) and "metric" (measure) 

  • Interestingly, the spelling that more closely matches Greek origins would actually be "pliometrics" 

Historical Context of Plyometrics

While the term was created in 1975, the training method itself has much older roots:

  • Eastern European countries were using these techniques as early as the 1920s
  • Initially known as "jump training" or "stretch shortening cycle"
  • Gained widespread recognition during the Cold War era when Eastern European athletes demonstrated remarkable athletic performance 

Wilt himself acknowledged that while the term might not be perfect, it was the best description he could develop for this explosive training methodology that focuses on increasing muscular power and athletic performance.

 

How did plyometrics evolve from "jump training"

Plyometrics evolved from "jump training" to its current form through several key stages:
Origins in Eastern Europe: The concept of jump training emerged in Eastern European countries as early as the 1920s, gaining prominence in the 1950s when Soviet Olympians began using these techniques.
Coining of the term: In 1975, American track and field coach Fred Wilt coined the term "plyometrics" after observing Russian athletes performing jumps in their warm-ups. He derived the word from Greek roots, combining "plio" (more) and "metrics" (measure).
Introduction to the West: In the early 1980s, Fred Wilt collaborated with trainer Michael Yessis to disseminate information about plyometrics in the United States.


Two forms of plyometrics emerged:

  • a) Original version: Developed by Russian scientist Yuri Verkhoshansky in the late 1960s and early 1970s, known as the "shock method." It involved dropping from a height and quickly transitioning to an upward jump, with execution times of 0.1-0.2 seconds.
  • b) Broader interpretation: A second version, more prevalent in the United States, expanded the definition to include various forms of jumps regardless of execution time.
  • Expansion and popularisation: As the term gained popularity, plyometrics evolved to encompass a wider range of explosive exercises, including jumps, hops, bounds, and throws, all aimed at improving power and athletic performance. This evolution has led to plyometrics becoming a mainstream training method used by athletes worldwide to enhance power, speed, and overall athletic abilities

Overview of Plyometrics

Plyometrics, also known as jump training or plyos, is a form of exercise that emphasises explosive movements to enhance muscle power and athletic performance. This training method is particularly effective for athletes in sports that require rapid and powerful movements, such as football, volleyball, and track and field.

 

Key Concepts of Plyometrics


Definition and Mechanism of Plyometrics


Plyometric training involves exercises that utilise the stretch-shortening cycle (SSC) of muscle fibers.

This cycle consists of three phases:

  1. Eccentric Phase: The muscle lengthens under tension, which stores elastic energy.
  2. Amortisation Phase: A brief transition where the muscle prepares for contraction.
  3. Concentric Phase: The muscle contracts quickly, using the stored energy to produce a powerful movement.

The effectiveness of plyometrics lies in its ability to train fast-twitch muscle fibers, which are crucial for generating explosive power.


Benefits of Plyometrics 

  • Increased Muscle Power: By training the muscles to exert maximum force in minimal time, plyometrics significantly improve power output.
  • Enhanced Athletic Performance: Athletes experience improved speed, agility, and coordination, making it beneficial across various sports.
  • Improved Neuromuscular Coordination: Regular plyometric training enhances the nervous system's ability to coordinate movements efficiently.
  • Versatility and Accessibility: Many plyometric exercises require little to no equipment and can be performed almost anywhere
