Height Weight

Training Load

•  Training Volume – Duration of training: (Time, Distance, Tonne)

•  Training Intensity – How hard your training (heart rate, oxygen

consumption, weight lifted, power output, blood lactate concentration perception of effort during training)

Training load = training volume x training intensity

Recommendations

•  Monitor Height every 3-4months –  Identify Peak Height Velocity –  Identify Early or Late Developers

•  Monitor Weekly Training Load – Reduce the chance of growth related injuries

Should Children Strength Train?

What Do you Think?

How Young is too Young? •  Israel by Sadres and colleagues (2001) Studied the effects of

progressive resistance training

•  2 groups 1.  27 boys (9-10 years) Resistance Training over 2 years 2.  22 similar boys participated in standard physical education classes

•  Each Group performed activities twice per week for 1hr •  Each strength session consisted of 150 reps •  Gained 1 % increase in strength per week over the controlled group!

•  Only 1 injury in 2 years (Bar hitting thighs)

How Young is too Young? •  Positive results from resistance and martial

arts training in 6-8 year old boys. Falk and Mor (1996)

•  A study with 32 girls and 64 boys between the ages of 6-12 years that demonstrated that 1 RM testing using child-sized weight machines was safe and effective. Faigenbaum et al. (2003)

Avery Faigenbaum

The most prolific researcher in this area.

In a review paper titled: “Resistance training for Adolescent Athletes” he 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).”

How heavy is too heavy?

American Academy of Pediatrics (AAP)

“Preadolescence and adolescence should avoid competitive weight lifting, power lifting, body building and maximal lifts

until they reach physical and skeletal maturity.” (AAP 2001 p 1471)

“Progressive resistance exercise requires the successive

completion of 8 to 15 repetitions in good form before increasing weight or resistance”

(AAP 2001, p 1471)

US National Strength and Conditioning Association

(NSCA) “Depending on the goal of the training program (i.e., strength or local muscular endurance), 1 to 3 sets of 6 to 15 reps performed on 2 or 3

nonconsecutive days a week is recommended.”

(NCSA 1996 p 71).

American College of Sports Medicine (ACSM)

“Strength training with maximal weights is not

recommended because of the potential for possible injuries related to the long bones,

growth plates, and back.” (Faigenbaum & Micheli, 1998 p 2).

Safely estimating maximal strength

Repetitions till fatigue (RTF)

•  Used for young and less experienced resistance trainers

•  Lighter resistances

•  Technique emphasized at all times

•  Extrapolate predicted 1RM with repetitions up to 20 reps

Scenario •  Client lifted 40 kg for 9 repetitions

– 1RM would be: – 40 x conversion factor of 1.22 = 48.8 kg

•  Another client lifted 40 kg for 12 repetitions – 1RM would be: – 40 kg x conversion factor of 1.31 = 52.4 kg

ASCA Recommendations on

training intensity

ASCA Level 1

•  6-9 years of age – modification of body weight exercises –  light resistance (brooms and bands etc) – work only for relatively high repetitions eg 15+

reps

ASCA Level 2

•  9-12 years of age: – 10-15 RM – Maximal loading approximately 60% 1RM – Predominantly simple free weight exercises – Machine exercises where the machine is an

appropriate size for the child.

ASCA Level 3

•  12-15 years of age: – 8-15 RM – Maximal loading approximately 70% 1RM – Progressively more free weight exercises – Avoiding complex lifts such as cleans, snatches,

deadlifts and squats

ASCA Level 4

•  15-18 years of age: – 6-15 RM – Maximal loading approximately 80% 1RM – Progressively moving towards an advanced adult

program involving split routines

Strength Training Recommendations

•  Complete a comprehensive introduction to gymnasium safety

•  Minimum Age: 6 years of age provided they have the maturity to follow instructions

•  Follow LTAD Model and incorporate ASCA Levels

•  Test strength using “repetitions to fatigue test” in young and less experienced

7 Take Home Messages…

1.  Think about growth stages rather than ages

2.  Think how changes in physical proportions will affect performance

3.  Help children understand the changes taking place in their bodies

4.  Set standards of performance according to developmental age not chronological age

7 Take home messages…

5.  Group children according to physical development, using height and weight as a guide

6.  Encourage skill learning for all your athletes, late developers could be very successful later

7.  Don't use exercises which place excessive force on bone growth regions during periods of maximum growth
