Strength training guidelines for children

By Licinda Liebenberg & Dr. Kim Nolte

Can children participate in strength training programmes?

Strength training can be defined as a method of improving muscular strength by gradually increasing the ability to resist force through the use of free weights, machines, or the person's own body weight. Strength training sessions are designed to impose increasingly greater resistance, which in turn stimulates the development of muscle strength to meet the added demand (Baechle et, al 2000).

The American Academy of Pediatrics and the National Strength and Conditioning Association (NSCA) have proposed that children can safely perform strength training provided the programme is adequately planned and supervised. Furthermore, the Surgeon General’s report on physical activity and health also encourages children aged six and older to develop and maintain muscular strength and endurance.

Despite the known benefits of strength training for children - teachers, fitness instructors, and youth coaches are often not sure how to proceed, and they end up watering down adult versions of strength training programmes. Ideally, children should be properly evaluated by a health care professional that can prescribe a training programme that is in accordance with the needs and abilities of the child.

Important considerations when prescribing strength training programmes for children

Important aspects to bear in mind when prescribing strength training programmes for children include:

Training age. Training age refers to the length of time a child has had any form of strength or resistance training. If a child has not done any form of strength training it is important not to start off with heavy weights but rather to use resistance bands or own body weight exercises.

Two or more years. A child needs to be physically active for two or more years before adapting or increasing work load.

Emphasise flexibility. During periods of rapid growth the muscles around the joints and growth plates are very sensitive and often tight. Therefore proper stretching and flexibility exercises should be included in a child’s training programme.

Developed nervous system. The reactions and movement skill of a child must be taken into consideration when prescribing strength training exercises. Not all children develop their motor skills equally.

Body type. The body type of a child also needs to be taken into account when prescribing strength training exercises for children. For example, mesomorphic children generally have more developed musculature and broader shoulders. Endomorphic children have rounder and broader hips, while children who mature late tend to be ectomorphic, slender and tall.

Guidelines for prescribing strength training programmes for children

The following guidelines should be adhered to when prescribing a strength training for children in order to ensure the programme will be both safe and effective in bringing about the desired changes.

  • The very first approach to creating an exercise routine is always to begin with a range of 8 – 15 repetitions. The resistance should be selected such that the child can complete the set amount of repetitions.
  • A frequency of two times per week for duration of eight weeks (Baechle & Earle, 2000; Malina, 2006).
  • You need to make sure that workouts are spread out enough to get no less than one to two full days of relaxation between routines.
  • The target whenever working out should be on correct form/technique of each exercise carried out, rather than on the amount of weight being lifted.
  • Increase resistance gradually and only when the child can perform the specified number of repetitions with good form.
  • Use equipment that is appropriate for the size, strength and maturity of the child.
  • Prior to exercising, warm up and stretching should be carried out.  Start your children with gentle loads and then make adjustments accordingly. 
  • No more than three consecutive exercise sessions carried out per week. 
  • You must also make sure that they drink plenty of water just before, during and right after exercise. 
  • Teach your child what their true capabilities are and stay safe and positive with them.
  • Emphasis should be placed on fun and enjoyment.
  • Set goals that are realistic and appropriate.
Examples of strength training exercises for children

Here are some examples of strength training exercises that are safe for your child to do, provided the guidelines mentioned are adhered to.

1.    Bench Press

The bench press works the muscles of the chest, shoulders and upper arms. Lie on a bench, with your feet on the ground. Hold a barbell or dumbbells in your hands slightly wider than shoulder width, with your arms extended above your chest. Slowly lower the weight toward your chest. When the barbell touches your chest or the dumbbells are at chest height, extend your arms again to press the weight back up to the starting position.

2.    Squats

Squats work a variety of muscles in the upper legs and buttocks. Stand with your feet slightly wider than shoulder width. Hold a weighted barbell on the top of your back, or hold dumbbells at your sides. Flex your knees and hips to lower your thighs until they are parallel to the ground, and then extend your knees and hips to return to the starting position. Keep your back straight and your head up throughout the movement.

3.    Push-Ups

Push-ups use body weight for resistance to the muscles of the chest, shoulders and the back of the upper arm. Lie face-down on the ground. Bend your arms, and place your hands on the ground, outside and below your shoulders. Also, anchor your toes on the ground. Push against the ground to lift your trunk and legs. When your arms have fully extended, lower your body back to the starting position. Keep your head, back and legs aligned throughout the exercise.

4.    Chin-Ups

Like push-ups, chin-ups also use body weight for resistance. Chin-ups work muscles on the back, shoulders and armsespecially those that flex the arms at the elbow (the brachialis and biceps brachii muscles). Hang from a bar, with your hands no wider than shoulder width and your palms facing your body (the bar should be high enough so your feet do not touch the ground). Pull your body upward until your chin is over the bar, and then slowly allow your arms to extend back to the starting position.
