Ultimately this mechanism results in the enhancement of the neurologic system to allow neuromuscular coordination to become more automatic.
Plyometrics increase neuromuscular coordination by training the nervous system and making movements more automatic during activity training effect.
This is known as reinforcing a motor pattern and creating automation of activity, which improves neural efficiency and increases neuromuscular performance.
The increase in performance often occurs without a concomitant increase in morphological changes within the muscle. Davies and Matheson 27 indicate clinicians should make the training specific to the individual goals of each patient. The authors of this manuscript believe that each specific movement pattern involved in the activity should be trained initially in isolation to work each kinematic chain link, allowing the sports activity to be dissected into smaller components and trained with isolated movements first.
Then, smaller components can be integrated back into a total coordinated movement pattern.
If a muscle cannot function normally in an isolated pattern, then it cannot function normally in an integrated pattern. The authors of this manuscript feel that plyometric training should be preceded by and coincide with other forms of resistance and flexibility training until and adequate base foundation of strength and flexibility has been established.
Plyometric exercises need to be integrated into the totality of the rehabilitation or conditioning program. One way to design the program is through the application via the periodization model.
The plyometric program should use the principles of progression and overload. This can be accomplished by manipulating the volume dosage reps, sets, weight, etc. The quality of the work is more important with plyometrics than the quantity of the work. Additionally the rate of the muscle stretch is more important than the length of the stretch.
During the training session, if the quality of the movement performance deteriorates and is not able to be performed correctly, then the athlete is probably experiencing fatigue and the plyometric portion of the exercise session should be terminated.
Based on the rest, recovery and reparative phase following high intensity resistive plyometric exercises, there should be increased recovery time when compared to other types of exercise. Most of the recommendations are empirically based upon Level 5 evidence with minimal scientific research supporting any of the recommendations.
Wilk, et al 12 , 82 , 83 disagrees and recommends plyometrics be used only in the first and second preparation phases of training according to the periodization model. The amount of total work in repetitions, sets, etc. The ROM can be performed throughout a larger range via an exaggerated movement pattern.

The concept is to employ the muscle activation and stretch reflex within a specific ROM. As previously described, the reflex mechanisms help facilitate the movement pattern to enhance the force production. Temporal Overload: Timing Temporal overload can be accomplished by concentrating on executing the movement as rapidly and intensely as possible. The temporal overload, or keeping the time to rebound amortization phase as short as possible, is one of the keys to performing plyometric exercises for increased power production.
Intensity Intensity is the actual percentage of effort required by the athlete to perform the activity. In plyometrics, the type of exercise performed controls the intensity. Plyometric exercises can come in many forms and intensities. Some activities such as bilateral jumping to a box are lower level plyometrics while others such as single leg jumps from a box are intense.
These variables must be considered when designing conditioning or rehabilitation programs. Volume Volume is the total work performed in a single work session or cycle periodization.
In the case of plyometric training, volume is often measured by calculating the load, counting the number of repetitions, sets, etc. Volume should be increased in a progressive manner to decrease risk of injury or overtraining. Different types of resistance training e.
Effects of plyometric training in untrained youth primarily follow the principle of training specificity. Despite the fact that only 6 out of 75 comparative studies investigated resistance or plyometric training in trained individuals, positive effects were reported in all 6 studies e.
Conclusions The present review article identified research gaps e. Introduction For many years, the effects of resistance and plyometric training in youth and its potential benefits and harms were among the most debated research topics in exercise science and physiology.
During the s and 80s, researchers and scientific societies postulated an increased risk of sustaining injuries when conducting resistance training because of the immaturity of the skeletal system [ 1 — 3 ]. In addition, it was argued that resistance training in youth is ineffective due to a lack of circulating anabolic hormones [ 4 ].
By contrast, nowadays resistance and plyometric training is deemed to be a crucial component of a health promoting lifestyle in young individuals [ 5 ]. Furthermore, muscular fitness is positively associated with the subjective evaluation of the own worth regarding self-esteem [ 18 ].
The current position statement on youth resistance training of the UK Strength and Conditioning Association even concludes that children and adolescents may increase their risk for negative health outcomes during adulthood if they do not participate in physical activities that build up strength and improve motor performance skills [ 12 ].
Previous meta-analyses tried to address this question by means of meta-regressions and subgroup analyses.
For example, a previously published meta-analysis revealed that resistance training induced strength gains only slightly increased with chronological age [ 6 ].
The same meta-analysis showed that the intervention period and the number of performed sets positively affected the outcome. In another meta-analysis, it was found that resistance training induced improvements in fundamental and sport-specific movement skills significantly decreased with increasing chronological age of the participants [ 15 ].
By contrast, no other training modalities describing the volume e. The difficulty in identifying relevant moderator variables from meta-analyses may reflect the inherent flaws of this methodological approach.
Even though random effects models adjust for some of the resulting statistical heterogeneity, important dissimilarities between studies get lost and may lead to erroneous conclusions. He has competed in weightlifting, cross-country skiing, and rowing and has won national titles and masters championships in all three sports.
Farentinos earned his PhD in biology from the University of Colorado and spent many years as a professor and researcher at various universities, including Colorado, Michigan, Ohio State, and Johns Hopkins.
He has published extensively in scientific journals and has written wildlife stories for children as well as numerous lay articles on exercise, health, and fitness. In the s, Farentinos owned and managed a sport and fitness center in Boulder, Colorado, designated as an official training facility for the U. At the center he trained and coached Olympic and professional athletes in cycling, running, triathlon, Nordic and alpine skiing, weightlifting, climbing, and mountaineering. During that time he also worked with athletes and coaches at the U.
Olympic Training Center in Colorado Springs. He participated in the Winter Olympics in Calgary as a technical representative for one of his ski equipment sponsors.In terms of plyometric training, around-PHV boys appear to respond with larger performance improvements e.
Upper-Body Power Development Plyometric training is the coordinated use of the entire body in the expression of power. Volume Volume is the total work performed in a single work session or cycle periodization. Great book.
Consequently, the purpose of plyometric training is to increase the excitability of the neurologic receptors for improved reactivity of the neuromuscular system while desensitizing the GTO. Rehabilitation programs have dramatically changed over the past several years.
