A recent study published in Sports Health used systematic review and meta-analysis to look at current available evidence to support the use of strength training, plyometrics, and agility training in children and adolescents.
The evidence shows:
Children can improve strength by 30% to 50% after just 8 to
12 weeks of a well-designed strength training program. Youth need to
continue to train at least 2 times per week to maintain strength. The
case reports of injuries related to strength training, including
epiphyseal plate fractures and lower back injuries, are primarily
attributed to the misuse of equipment, inappropriate weight, improper
technique, or lack of qualified adult supervision.
Conclusion:
Youth—athletes and non-athletes alike—can successfully and safely
improve their strength and overall health by participating in a
well-supervised program. Trained fitness professionals play an
essential role in ensuring proper technique, form, progression of
exercises, and safety in this age group.
This is something which we have known for quite some time and is nice to see in systematic review form. We have long said, "Access does not equal know how!" and we see this time and time again in the athletes that have come to us to train. These are some of the areas best athletes who have access to weight room facilities at their high schools and/or are members at other gyms yet still do not know how to put it all together.
I believe the biggest take home message from this recent review is injuries can occur with any training but that the majority of injuries were linked to
- misuse of equipment
- inappropriate weight
- improper technique
- or lack of qualified adult supervision
Parents don't trust that your children know what they are doing when they go to the weight room. Make sure they are properly supervised and make sure those in supervision roles are properly trained themselves. Fitness professionals with the initials "CSCS" after their name are credentialed by the National Strength and Conditioning Association and are educated at least at the Bachelor's Degree level in a field related to exercise and or health care.
