Plyometrics are any exercise where the muscle is contracted eccentricly then immediately, concentricly. In plain English, the muscle is stretched (i.e. loaded) before it is contracted. A good example is push-ups with a clap in-between each push-up. Your muscle (pectorals in this case) is elongated and loaded by the downward force of your body, then immediately you must contract the muscle to push yourself back up.

and u would train in this fashion normally if u wanted to increase yr explosive speed/strength

hope that helps

Resistance training, skeletal muscle and growth.

Falk B, Eliakim A.

Resistance training in youth and its effectiveness, possible effect on growth and safety considerations, has received considerable public and scientific attention in recent years. Although few early studies questioned the usefulness of resistance training in children, numerous recent studies have demonstrated its effectiveness in both children and adolescents. Nevertheless, the optimal intensity and volume of training for youths of different ages requires further study. The increase in strength following resistance training in youths, especially in prepubertal children, is believed to be due mainly to neural adaptations and only minimally, if at all, to muscle hypertrophy. Few studies have examined the long-term effect of resistance training on growth. The few which have, found that, contrary to the common misconception that resistance training may retard growth. Scientific evidence indicates that resistance training results in increased serum IGF-I and that there is no detrimental effect on linear growth. Finally, numerous studies have demonstrated that with appropriate supervision and precautions, resistance training can be safe and effective for children and adolescents.

hey guys big thanks to all you that replyed i've got him doin alot of plyometrics and speedwork now so not long and he will be the best on the field cheers for all the replies

[Pseudonym]

Good stuff! Be sure to let us know how he gets on, and whether it helps his game any.

In response to Pseudonym's question about people being skiny because they dont play sport.

I played alot (7+ times a week in training and games) of hockey as a kid and tennis and cricket in the summer time and i was skinny and weak as at age 18. So i think its mostly genetic. Unless i train really hard I lose heaps of muscle really fast.

Think its just because my body likes to feed off itself. Perhaps if i'd eaten 8 meals a day as a kid it would have been better though...

well it wouldnt be ideal to be bulky for these sports...

and playing these wouldnt bulk u up either

[james123]

To be honest I think it really depends on the maturity of the person. When i was 11 i wasnt huge i was tiny so weights were not an option because my body just wasnt ready for them, however, there were several maori kids in my class that were 6ft plus so they were ready. You cant put an age on this its all to do with the persons body.

Im sure it would be fine, just dont get him to do anything heavy. Keep reps high and weight low and stay away from spine compressing exercises like heavy squats until he's older.

This thread immediatly reminded me of Little Hercules http://www.richardsandrak.com/new%20pic%20003.htm .

Dude is 5'7 at 15. I wonder if the weights had anything to do with that or if he just had short genetics...

[2guns]

Dude is 5'7 at 15.

thats not that short for 15, some dont stop growing till 21 or older
