When Should Kids Start Strength Training: Part Two


You can find the first part of this article on when the time is right to begin your child in a strength andconditioning program here.

The decision has been made, the sessions have been bought and planned out, and your child is ready and rearing to go.  This second part of the article is going to take a look at what a strength and conditioning program should look like.  

But first, let’s dispel some common myths about kids and strength training.

Myth #1: Lifting Will Make Kids Short 

This is a very common myth and it is one that has been repeatedly busted in the scientific literature (Ratel).  The fact of the matter is that the body, and growth plates in particular, are subjected to much higher load and shearing forces when running, jumping, and changing direction than when they are performing lifts, bodyweight and otherwise, in a controlled and safe manner.

Myth #2: Kids Will Get Bulky 


For females and kids that compete in weight class divided sports in general this is a legitimate concern.   It’s a highly unfounded myth that is propagated by the media but legitimate nonetheless.  The fact of the matter is that these athletes are not hormonally capable of huge increases in muscle mass.  Before a male goes through puberty he isn’t producing a lot of testosterone.  If you are a normally functioning female you aren’t either.  


The literature shows that females and pre-pubescent males have about a tenth of the testosterone production as normal males.  Testosterone is a requisite compound to build muscle.  If you don’t have a lot of it you won’t build a lot of muscle.  You can get stronger, faster and more coordinated without it.  You just won’t get a lot bigger.

Myth #3: Kids Won’t Get Stronger


This goes back to number two.  It’s true that kids won’t see strength gains because of gains in muscular size.  But they will see strength gains due to an improvement in neurological function.  Your muscles and the nerves that send them the signals to move will become more efficient.  This means you will be able to use all or most of the muscle fibers that you have instead of a smaller percentage.  This means stronger, faster, and more coordinated athletes.

Now that we’ve dispelled the common myths let’s take a look at what the major points of emphasis should be in a youth’s strength and conditioning program.

Point of Emphasis #1: Mobility and Soft Tissue Work

Mobility and soft tissue work should not just be a corner stone of training programs for youth athletes, but for all trainees regardless of age, sex, or sport/activity.  The fact of the matter is that often times improving one’s mobility through soft tissue techniques will make trainees stronger.  This is because with improved mobility comes less resistance to put the body into postures and through ranges of motion that will lead to athletic success.  I.e. it makes moving easier.  When moving is easier you spend less energy on repetitive motions like running and jumping.

Mobility and soft tissue work is especially important for athletes that are growing.  Bones will often grow faster than the muscles can keep up.  This can lead to tight and weak muscles especially along the long bones such as the hamstring, quadriceps, calf muscles, and biceps brachii.  Using soft tissue techniques such as foam rolling, stretching, and activation drills, one can help the muscles elongate with the bones and keep them strong as they grow in length.

Point of Emphasis #2: Bodyweight Movements

The number of kids I see on a daily basis that start out not being able to do a push up or a proper bodyweight squat, let alone a pull up, is no longer surprising, but still disheartening.  At the same time I hear kids talk about how they either hate gym class or don’t even have to take it.  Needless to say kids need to learn a thing or two about their own bodies and how to handle them.

If a youth athlete is brand new to strength training, regardless of perceived athletic ability, they should first work to master their own body weight and then master free weights.  There is no reason why every kid in America shouldn’t be able to do ten perfect pushups, five perfect chin ups, and an unlimited amount of bodyweight squats.

The ability to do these things is NOT something that is gained as we age.  It is something we lose.  Watch any three year-old horse around for ten minutes and you will see perfect bodyweight technique on squats, pushing themselves off the ground, and if an apparatus is available being able to hold themselves up on a chinning bar.  The other day I saw my girlfriend’s three year-old son put himself into a picture perfect RDL position.  And he was just watching TV!  The hip hinge of an RDL is something that if a kid doesn’t automatically get it can be very frustrating to teach.

At the end of the day body weight movements and lifts should be the cornerstone of any beginning program and should, at a minimum, be kept up to maintenance levels as the trainee ages and progress.

Point of Emphasis #3: Proper Lifting Technique and Selection

Proper lifting technique must always be paid attention to, to ensure safety and proper muscular development.  It is beyond the scope of this article to describe proper technique of different lifts.  The coach in charge of training young athletes should not only know how to perform each lift but should be able to properly teach the lift.

When performing different lifts, whether they are with body weight, free weight, or machines, young athletes should never work with maximal or near maximal weights.  Using repetition ranges from 5-15 will ensure a manageable load and proper technique.  Most weight room injuries in young athletes occur when attempting near maximal loads before the athlete is ready.  Zatsiorsky and Kreamer recommend the three year rule when it comes to attempting maximal lifts.  That is an athlete should have at least three years of proper weight room instruction doing the basic lifts before attempting a maximal or near maximal lift.  This will ensure that the musculature needed to attempt such poundages will be properly developed to handle the load placed upon them.

Young athletes should stick to basic multi-joint exercises such as pushups, pull ups, squats, lunges, dead lifts, and presses.  A good mix of these will in each session will ensure that athletes to not acquire overuse injuries by doing the same things repeatedly for each session.  Single joint exercises (except for possibly hamstring curls) such as bicep curls and calf raises will not lead to any type of athletic enhancement and should be reserved for later in the athletes progression.

Point of Emphasis #4: Muscles to Be Trained

The sooner athletes begin to pay attention to different muscle groups the better.  This musculature includes, from top down, the upper back, the spinal erectors, the abdominal wall and obliques, and the muscles that attach to the hips (gluteals, hip flexors, quadriceps, hamstrings, and adductors).

When athletes attempt to “play themselves into shape” -only participating in sport practices to get ready for competition- certain muscular imbalances will occur.  Many times the muscles of the upper back, the gluteals, and the hamstrings will be underdeveloped, tight, and weak while the muscles of the upper chest and shoulder, the quadriceps, hip flexors, and calf muscles will be overactive and tight.  These imbalances will lead to improper postures and ranges of motion during practice and competition and will ultimately lead to a decrease in performance.

Proper execution of the exercises listed above, along with attention being paid to soft tissue and mobility work will help to decrease the imbalances and bring the body back into proper postural alignment.  Proper postural alignment makes movement much more smooth and efficient and leads to an increase in performance.

Point of Emphasis #5: Being Able To Stop

Many coaches tend to only focus on getting kids to be able to run fast, but few teach the proper way to decelerate and stop once the athlete has started running or is coming down from a jump.  This point of emphasis ties into all of the above points in that without proper mobility, body awareness, and proper muscular development this skill will be severely lacking.

Very few sports happen in a straight line with no deceleration component.  Track and field, cross country and swimming are the only ones that come to mind.  Most sports require athletes to change direction, run at different angles, and stop on a dime.  Being able to properly control your body weight and put it in the proper posture during the deceleration phase and the subsequent acceleration phase will lead to greater efficiency when changing direction and ultimately a fast athlete.  When athletes lack this skill the movements are very inefficient and often times place undue stress on the ankle, knee, hip, and low back.

Summary

The design and implementation of strength and conditioning programs for the youth athlete should be built on the basics.  Basic exercises used to develop proper movement patterns and solid body weight strength are the best way to build a solid foundation for athletic development as the athlete ages.  Do not have youth athletes attempt maximal strength attempts until they have a solid foundation of strength and have shown the ability to maintain correct posture throughout the entire movement.  Always teach and strive for efficiency and proper mechanics during movement training, especially when it comes to changing direction and stopping.  A well thought out plan and progressions are vital to enhancing athletic ability while at the same time ensuring the safety of the athlete.
