Plyometrics is re-placeing core training I see.
Whats your take on this method of training.
I bet sprained ankles will be the most treated Gym injury this year as a result of this form of training.
Whats your take?

I was a sprinter on my college track team. Not only did I spend a lot of time in the weight room and getting a lot of mileage, but I did a lot of plyometrics. I think they are a great way to develop explosive power, especially when in addition to squats, deadlifts, and power cleans. Explosive power is what a sprinter needs to get out of the blocks.

I've been coaching soccer for about 20 years. I used plyometrics in it's early years to increase my 3-step explosiveness when I played and I swear by it for that purpose. I have used the methods off-season for the higher level teams I coach and have seen some great results.
I feel the love for the program for these purposes. I am not to sure to what advantages in carido or core strenghting priniciples this might add. This will most definitley put wear and tear on the ankles and knees if not done right, I know for most of us, at our age, we are pushing the joints to their limits as it is.MILITARY RETIRED

bama and hap make some good points. As I mentioned before I used it for soccer training and as a sprinter. It got me to 4.3 speed because I was so explosive out of the blocks. My 100 (yards not meters) time could not break 10.2 though, indicating all my speed was right out of the blocks.
Could we as Hap said maybe go some with padding? Bama's point of being able to explode in squats and deads has merit.
I have a book or two on the subject, maybe it's time I blow the dust off and revisit it.MILITARY RETIRED

I have only been exposed to this in conversation with a few guys at the gym, basically as I understand it, its techinques to increase power. Power is when strength is converted into speed, the whole point being improved athletic performance not necessarily muscle definition or volume.
Dont see much of it at my gym, but if anyone has a good website on it I would love to read it.Sig = not worth the petty B.S.

I did, I usually goto Wikepedia for data, its a decent source: http://en.wikipedia.org/wiki/Plyometrics
Reading through it briefly it strikes me as an athlletic performance enhancing theory and not necessarily consistant with Body building. While power is important to get muscle fibers to a higher level of endurance (and then by default growth) Plyometrics seems to be geared more for the football/soccer/track and field athlete who needs quick bursts of maximum intensity and output.Sig = not worth the petty B.S.

There is some 'implication' in doing plyometrics on a soft surface, however that is only to be utilized when the athlete is already doing a high amount of impact type training.
My website is down right now or I'd post the link to my article on Plyometrics.

Purpose: The purpose of this study was to investigate the effects of 9 months of plyometric jump training on bone mineral content (BMC), lower extremity performance, and static balance in adolescent girls (aged 14.6 +/- 0.5 yr; 22.7 +/- 14.0 months past menarche)..........
.....Conclusion: The trends observed in bone mass between groups suggest that plyometric jump training continued over a longer period of time during adolescent growth may increase peak bone mass.The Effect of Neuromuscular Training on the Incidence of Knee Injury in Female Athletes
A Prospective Study

To prospectively evaluate the effect of neuromuscular training on the incidence of knee injury in female athletes, we monitored two groups of female athletes, one trained before sports participation and the other not trained, and a group of untrained male athletes throughout the high school soccer, volleyball, and basketball seasons. Weekly reports included the number of practice and competition exposures and mechanism of injury. There were 14 serious knee injuries in the 1263 athletes tracked through the study. Ten of 463 untrained female athletes sustained serious knee injuries (8 noncontact), 2 of 366 trained female athletes sustained serious knee injuries (0 noncontact), and 2 of 434 male athletes sustained serious knee injuries (1 noncontact). The knee injury incidence per 1000 athlete-exposures was 0.43 in untrained female athletes, 0.12 in trained female athletes, and 0.09 in male athletes (P = 0.02, chi-square analysis). Untrained female athletes had a 3.6 times higher incidence of knee injury than trained female athletes (P = 0.05) and 4.8 times higher than male athletes (P = 0.03). The incidence of knee injury in trained female athletes was not significantly different from that in untrained male athletes (P = 0.86). The difference in the incidence of noncontact injuries between the female groups was also significant (P = 0.01). This prospective study demonstrated a decreased incidence of knee injury in female athletes after a specific plyometric training program.The Effects of Plyometric training on the Shoulder Internal Rotators

This commentary presents the rationale for training programs to reduce the incidence of knee injuries. Our studies have revealed that the external knee loading patterns during sidestep cutting are what put the anterior cruciate ligament at greatest risk for injury. Compared to running, sidestep cutting involves similar levels of knee flexion loading but increased loading in varus-valgus and internal rotation of the knee, and these external loads need to be stabilized or supported by the internal structures of the knee. People use a generalized hamstrings and quadriceps co-contraction to stabilize these external loads, thereby reducing ligament loading. It is proposed that perturbation of the joint receptors reinforces the use of selective hamstrings and quadriceps co-contraction patterns superimposed on a generalized co-contraction pattern. This is not by immediate ligamento-muscular protective reflex, which is too slow to provide any adequate support, but by enhanced proprioceptive information that may be used in learning. In contrast, the immediate effect of muscle stretch reflexes would be to reduce co-contraction, a possibly negative outcome for joint stabilization. The effects of different types of training on the control of joint stability are examined. It is proposed that resistance training may not be appropriate because it enhances muscle stretch reflexes, which may reduce co-contraction, and produces no reductions in voluntary activation times and time to peak torque. However, stability and balance training is thought to suppress muscle stretch reflexes and, in turn, enhance co-contraction. Also, stability and balance training that stimulates the knee joint ligament and capsular receptors may reinforce co-contraction patterns to facilitate greater improvements in joint stabilization. Stability and balance training and plyometric training produce reductions in voluntary activation times and times to peak torque, which may decrease muscle response times so players are more able to perform rapid and unexpected sports maneuvers. Training programs that emphasize these neuromuscular mechanisms may enhance protection of the anterior cruciate ligament and reduce the incidence of injury.

Great info, reps!!
I have always been a fan of plyometrics. Used it alot myself years ago and swore by it. Have been using it for a few years training college bound soccer players. I sometimes run across skeptics due to the impact. This info will help me show the benefits.MILITARY RETIRED

If you are interested in a soft surface to do plyos on, a field (soccer or football) is always a good place. Also, is you find a rubberized track that was made more for distance running then that will do. Dictance tracks are a softer rubber and sprint tracks are a much harder rubber.

I'll never do it. I'm not as flexible as I used to be. On the other hand, my youngest son (6th grade) has used this method and it must have paid off. He has the quickest 40yd dash, 100M dash times and highest vertical jump in his class.
So...younger people will probably benifit from this more than someone my age.47yr male, 5'11", 235lbs, BF who knows? (Oct 05)
