The key concepts to consider as precursors to beginning a comprehensive strength training program are:
- Build a broad a base of activity and general fitness
- Build a firm foundation in movement skills
- Young growing athletes are not miniature adults therefore we must adjust everything to the size, weight and maturation level of the youngster
- Always weigh biological age against chronological age
- Always teach first then train. Do not assume that because it is taught that it is learned. Make sure that the skill or movement is mastered before you let the athlete begin to train with a particular exercise or method.
- Incorporate variety as much as possible to force adaptation and to maintain mental freshness.
- Machines are not necessarily safer, they must fit the athlete, most machines do not.
The following chart is adapted from: Growth and Development Considerations for Design of Training Plans for Young Athletes by Lyle Sanderson. SPORTS. Volume 10 #2, 1989. This chart can give us a good template to guide the progression of strength training throughout the athletic lifespan.
Phase / Duration of Phase / Stage of Development
Initiation / 3-4 years / Early School Years
Basic Training / 5-7 Years / Pre-pubescent and during puberty
Buildup Training / 3-4 years / Post-pubescent
Systematic High Level Training / 6- 10 Years / Adulthood
The following are the stages of strength development relative to the stages of development in the above chart:
We are not East Germany or Bulgaria- Beware of false prophets bearing gifts, you do not have begin specializing in a single sport at this age to be successful in later stages. This should be very unstructured and should occur with a frequency as often as the youngster feels like participating. The key is to put the youngster in an environment where there are a variety of strength building activities are available.
Functional exercise criteria also apply to children. Therefore the exercise should engage the whole body in multi-joint, multi-plane activities that are of high proprioceptive demand. These criteria apply to all levels of development.
Start with developing a routine and good training habits.
During the early stages of this phase strength training workouts should be scheduled two to three times a week gradually increasing to four and possibly five workouts a week in the later stages of this age span.
The resistance spectrum begins with bodyweight and then adds loading such as weight vest or weighted belt that allows the body to perceive the resistance as an internal load. The next step is to add external loading in the form of medicine balls, stretch cord, and dumbbells. The last step is to add resistance in the form of a bar with weight. The key is to progress gradually through this spectrum with gradual incremental jumps that allow the young growing bodies time to adapt.
Strength is the precursor to speed. It is an enabler that will make significant improvements to agility, coordination (motor control). It can also make significant contributions to endurance by improving posture.
Teach technique of the Olympic lifts during the skill hungry years. Use a broomstick or a bar appropriately sized to the athlete’s bodyweight so that correct skill is ingrained.
We must also consider development of muscular bulk for the growing athlete participating in sports that demand this emphasis. This is necessary for armor or protection in collision sports like football and hockey to the increase body mass in the throws.
As far as training programs go, one size does not fit all. Ninth grade boys should not be on the same program as senior boys. There is too much of a gap in development. This phase has some of the biggest discrepancies in biological age.
This is the age where the greater proportion of work is done with external resistance in the form of free weights and dumbbells.
- Strength training equipment and implements must be of appropriate design to accommodate size and maturity differences.
- Do not base the strength training programs on chronological age; instead carefully consider biological age (maturation level).
- Strength training program should be bodyweight based, with the core strength and stability emphasized first.
- Overhead lifting or loading of the spine should be de-emphasized until sufficient core strength & stability is developed.
- The child must have the emotional maturity to accept instruction and follow a program.
- Strength training should be part of a comprehensive fitness program.
- Qualified adults must supervise the program.
