Archive for youth strength training

Following the series I wrote a week or so ago on youth resistance training I thought I would show you some clips or some of my younger athletes training. I put this highlight reel style video together a couple of years ago for the tennis programme that I was involved with.

Whilst the sport is tennis, the work is pretty general in nature and applicable to most sports.

Check it out and let me know what you think.

So far in this series the question of safety has been addressed, click here to read part 1.

In the second post the question of need and the benefits were examined, click here to read part 2.

This final part will address the question of readiness to train. Here we go!

Are they ready for it?

Avery Faigenbaum from the University of Massachusetts in Boston, who is perhaps the most prolific researcher in this area, In a review paper entitled: “Resistance training for Adolescent Athletes” stated:

“Although there is no minimum age requirement for participation in a youth resistance-training program, all participants should have the emotional maturity to accept and follow direction and should genuinely appreciate the potential benefits and risks associated with youth strength training.” (Faigenbaum, 2002 p 32).

From my point of view as a coach I look at pretty common sense factors to determine an individuals readiness to engage in a strength training programme. Heres a quick bullet point list:

1. Can they listen and follow instructions clearly? This is a must. If they can’t listen to what you’re saying they can’t be coached in this way. You’d be better off doing less focussed activities with them.

2. Do they have the emotional maturity to accept when they are doing things wrong and address these issues? If not then again better off doing less intense and focussed activites.

3. Do they have basic competency in key movements such as squats, lunges, push-ups, planks, core endurance holds, single leg squats etc etc. If not they better get this sorted first. Master your bodyweight before you add loads!

 If they pass these criteria then consider introducing them to basic strength work.  

 What does youth strength training look like?

Just to keep you going, heres a clip of one of my young athletes (14 at the time) performing deadlifts for strength:

Young athlete using deadlifts to build strength

Here’s a beginners programme taken from an excerpt from the ASCA (Australian Strength and Conditioning Association) position statement. Its a decent session in my opinion:

A beginning program would comprise a basic 3 day per week circuit type whole body program performed on alternate days (i.e. Monday, Wednesday and Friday) of the following exercises:  

Basic warm up (5 minute jog or cycle etc plus 2-3 minutes of dynamic stretching)

1. Step ups (both left and right legs) (quadriceps, hamstring and gluteal muscles) – 20 to 30 cm step or chair

2. Push ups (pectorals, deltoid and triceps brachii muscles) – off knees initially progressing onto toes as strength increases.

3. Star jumps (quadriceps, adductors, gluteal muscles).

4. Abdominal crunches (abdominals and hip flexors) – as strength increases progress towards bent legged sit ups.

5. Chair dips (triceps brachii muscle) – initially have legs close to the chair and use the legs and arms to raise the body. As strength increases progressively move legs further away from the chair.

6. 90 degree wall sit (quadriceps and gluteal muscles).

7. Reverse back extensions (lower back, gluteal and hamstring muscles) – lying face down with torso over table or bench and lift legs to level of hips hold top position for 1-2 s and repeat.

8. Hover (abdominal, hip flexor and lower back muscles) – initially off knees progressing to toes.

Cool down and stretch – (5 min jog or cycle etc and 5 minutes of stretching)

Progression:

Week 1: Perform 20 s of each exercise for as many controlled repetitions as possible followed by 40 s rest and then move onto the next exercise. Perform 1 circuit – total workout time approximately 25 minutes (including warm up and cool down). Once this circuit is comfortably achieved by the athlete progress onto stage 2.

Stage 2: Perform 30 s of each exercise for as many controlled repetitions as possible followed by 40 s rest and then move onto the next exercise. Perform 1 circuit – total workout time approximately 27 minutes (including warm up and cool down). Once this circuit is comfortably achieved by the athlete progress onto stage 3

Stage 3: Perform the same as stage 2 but repeat the circuit 2 times – total workout time approximately 38 minutes. Once this circuit is comfortably achieved by the athlete progress onto stage 4.

Stage 4: Perform 2 circuits but increase exercise time to 40 s per exercise with 50 s recovery -total workout time approximately 40 minutes. Once this circuit is comfortably achieved by the athlete progress onto stage 5.

Stage 5: Perform 2 circuits but increase exercise time to 50 s per exercise with 50 s recovery -total workout time approximately 43 minutes. Once this circuit is comfortably achieved by the athlete progress onto stage 6.

Stage 6: Perform 2 circuits but increase exercise time to 60 s per exercise with 60 s recovery -total workout time approximately 47 minutes.

At this stage the athlete can keep the same circuit but try and increase the intensity of some of the exercises. For example, some options include:

> Increasing the step height for the step ups

> Push ups off toes rather than knees

> Progress from crunches to bent legged sit ups

> Chair dips performed with legs progressively further from the chair

> Hover off toes rather than off knees

Although i’m not a lover of the crunches or the push-ups off knees, I think that the progression is sound and this programme will achieve results in the youngsters. The key point is that it is competency dependant not age/time dependant. Don’t progress someone just because they are older. Make sure they demonstrate the competence to progress.

Lastly, common sense I know, but machines are not the way forward, a good S&C coach working with children and adolescents should incorporate as much bodyweight and free weight type activities as possible. Unfortunately there are gyms aimed at kids out there that are basically scaled down machine weights. Completely non functional and against so many principles of athletic development. Heres an example taken from a local school near me.

 

 

 

 

 

 

 

 

 

 

 

This is more functional:

 

 

 

 

 

 

 

 

 

So in summary:

The child needs to have the emotional maturity to understand what they are doing and accept instructions.

The programme implemented needs to be progressive and competency based.

The modalities employed need to be functional, free weight movements that build multi-directional strength and body awareness.

Dont progress too fast, earn the right to move forwards!

Keep the sessions fun and enjoyable.

Thats all on this topic, think it has been pretty well covered!

Firstly, if you missed the previous post on youth strength training check it out here. It lays out the efficacy and safety of youth strength training and you should read it before reading this.

 Do they need it?

Although I would say that young people who want to improve sports performance will generally benefit more from practicing and perfecting skills of the sport than from resistance training.  In the days of sports being taken extremely seriously from a young age, the value of strength training to the young performer is increasingly important.

Take the early specialization high skill sports such as tennis, badminton, soccer and many more.

Rightly or wrongly participants are often undertaking 10 or more hours of one sport per week, and obviously becoming very skilled at these sports. However, the time spent developing sport specific actions also creates asymmetries and imbalances meaning that injuries occur frequently in these juniors.

I am not in favour of early specialization, my view is that children should play as many sports as they can and I would hope to go down this path with my own kids. But it appears that I’m in the minority, and these injuries are occurring in some of these sports.

If you are working with these sports as a trainer or S&C coach you really have to take the line of it is unethical to not be strengthening the key areas to give these kids a chance to continue playing.

On top of that you have a more sedentary youth population nowadays. Its all well and good saying play sports but are they really going to do it? Parents look to trainers and S&C coaches to provide that physical stimulus to their children as they won’t get it elsewhere.  It is a niche that is growing and provides fun and challenging work for us coaches.

To be honest, even in the late specialization sports such as rugby union the argument is exactly same, just a little more delayed.

Here’s a quote from the RFU position statement of youth strength training:

“Young rugby players need a long term, comprehensive skills and conditioning programme that includes well planned and supervised strength training from an early age. This is desirable for all young players who might eventually play club rugby as adults; it is essential for young players who aspire (realistically) to play at the elite level.

 Professional rugby players are increasingly large and powerful. England international forwards and backs in 2003 weighed, on average, 109 kg and 90 kg respectively, compared with 100 kg and 83 kg for their counterparts in 1991. A greater proportion of this additional weight in modern players is lean body mass, so more force is generated in the collisions. (England Rugby Injury and Training Audit 2002-04).

In order to compete in the professional game a young player must often become bigger, nearly always stronger and definitely more resistant to injury through the use of a strength training programme. Most players in England will not have been introduced to this type of training until 16 – in many cases 18 – years old. The player is then often “fast tracked” through a strength programme in order to prepare him for the rigours of the adult game. This is potentially injurious to the player if the necessary foundation work has not been done to enable him to tolerate the loads:

And young athletes are making the same mistake so many did in the 1950s and 60s.

They attempt to “play themselves into shape”. With high sport demands and forces acting on young bones, ligaments and tendons, sport related injuries have started to proliferate. Often injury is due to being physically unprepared to participate. Optimal resistance (strength) training may in fact be key to the prevention of injuries in high school athletes.

By the early 90s people realized young athletes needed to prepare their bodies as they were not able to meet the demands and resistance (strength) training may be of help in preparation and injury prevention”

(Michelis et al 1986 Paediatric and adolescent sports injury: Exercise and Sports Science Review, and Metcalf & Roberts 1993 Strength training and the immature athlete: An overview Paediatric Nursing 19 (4), quoted in Strength Training for Young Athletes p3 Fleck and Kraemer)

 

So I think that you need to accept that in many cases it is a required method of training.  Youth sports these days are extremely physically demanding and place great stresses on our childrens bodies. We know it is safe, there is astrong need for it. But what benefits can we expect to gain from prescribing S&C work for children and adolescents?

What benefits can be expected?

In a study conducted on junior weightlifters is was found that Bone mineral content of junior Olympic weight lifters was greater than those who do not lift (Convoy et al Medicine & Science in Sport & Exercise 25 1993, Virvidakis et al International Journal of Sports Medicine 11 1990).

Peer-reviewed research indicates that strength training may be beneficial to young athletes

players through:

_ the prevention of injuries

_ improved body composition

_ improved sports performance due to increased strength, power and muscular endurance

3 studies (reference shown below) show the benefits of resistance training in terms of strength gain and injury prevention. In preadolescents, proper resistance training can enhance strength without concomitant muscle hypertrophy. Such gains in strength can be attributed to neuromuscular “learning,” in which training in- creases the number of motor neurons that will fire with each muscle contraction.

It is clear that significant benefits can be gained through incorporating a progressive strength development programme with young athletes. The question is how? How do we put together the sessions? How do we know when to progress?

This is the topic for the final post in this series on youth strength training.

I thought I should contribute to this debate seen as I work with quite a few young athletes. At the current time I train a few tennis players under the age of 10, a few more under 13, and a ton of young athletes in as many sports as you can think of under 16!

its great work, much of which I do because I feel its important that the kids get the right coaching and develop in the right way rather than doing stupid stuff with a clueless teacher, coach or trainer.

Anyway with that being said I think there are quite a few questions to answer and I got a bit carried away writing it so decided to split into 3 parts.

The main questions are:

Is using weights with children and adolescents dangerous or harmful to their development?

Do they need it? Are they beneficial? Is there any point in training children with weights?

Are they ready for strength training? And what should they start out with?

This post will answer the question of safety  and two follow up posts will answer the question of the benefits and the need for strength training with our young whipper snappers as well as how a programme should start.

Is resistance training safe to use with children and adolescents?

This one really gets me going….I can’t count how many individuals be they parents, trainers, even S&C coaches who have said to me that children (as in pre-puberty) and adolescents (as in during/post puberty) shouldn’t start with weights until 16, 18 or some other random number for that matter.

Well if that’s the case then they shouldn’t be playing sports either as statistics have shown that supervised weight training is safer than nearly all sports when it comes to injuries per 1000 hours of playing and there are a couple of studies that illustrate this. The highlights of which are shown below:

In a 21 month study, taken from the Australian Strength and Conditioning Association’s position stand on youth resistance training, which was carried out on males aged 9 and 10 who were engaged in regular strength training programme there was one injury reported of which the details are shown below:

“… on one occasion the bar slid and fell on the thighs of one of the subjects following a lift (clean). The child complained of transient non-specific pain in the anterior thigh and sat out for about 5 min. He returned to train within the same session when the pain was resolved and had no further complications. Therefore, it was felt that no additional medical evaluation was required. The calculated injury rate was 0.055/100 participant-hours.” (Sadres et al., 2002 p 363).

A study conducted by Brian Hamill of the British Weight Lifting Association reported injury rates in a variety of recreational sports per 100 participant-hours. The results are shown below:

_ resistance (strength) training 0.0035

_ weight lifting for sport 0.0017

_ soccer 6.20

_ basketball 0.3

_ football 0.1

(Relative safety of weight lifting and weight training B. Hamill Journal of Strength and Conditioning 1994).

Both of these studies clearly show that supervised weight training is safe for youngsters to engage in regularly in terms of immediate injuries, but what about the long term effects of strength training with children?

Long term effects?

In November of 2006 an evidence based review paper (Clin J Sport Med. 2006 Nov;16(6):478-87. Weight training in youth-growth, maturation, and safety: an evidence-based review. Malina RM.) concluded:

Experimental training protocols with weights and resistance machines and with supervision and low instructor/participant ratios are relatively safe and do not negatively impact growth and maturation of pre- and early-pubertal youth.

The American academy of pediatrics states in their position stand on youth resistance training (available here) that

‘A limited number of case reports have raised concern about epiphyseal injuries in the wrist and apophyseal injuries in the spine from weight lifting in skeletally immature individuals. Such injuries are uncommon and are believed to be largely prevent- able by avoiding improper lifting techniques, maxi- mal lifts, and improperly supervised lifts.

Strength training programs do not seem to ad- versely affect linear growth and do not seem to have any long-term detrimental effect on cardiovascular health. Young athletes with hypertension may experience further elevation of blood pressure from the isometric demands of strength training.’

They also go on to say that:

‘Strength training programs for preadolescents and adolescents can be safe and effective if proper techniques and safety precautions are followed.’

The RFU (rugby football Union) position stand also states that Strength training may enhance bone development in younger children (Mackelvie et al, British Journal of Sports Medicine 36 2002).

So in terms of safety I think that addresses the question of strength training with youth populations. In summary:

-       Supervision is key! Do not let youngsters lift weights on their own just as they wouldn’t play rugby on their own.

-       Weight training is one of the safest activities for kids to engage in with supervision. Safer than the majority of sports out there              in fact.

-       There are no long term negative effects of weight training.

The next questions are do they need it, and what are the benefits?

This will be discussed in the follow up post so stay tuned!
