Design a training program to prevent growth plate injuries Bones do not fully fuse until we are in our late teens or early twenties. This can create concern about whether exercise will impact on a child’s bone growth and whether children are at higher risk of injury. Instead of a fully fused bone, children have a growth plate at either end of their long bones. This is made up of growing tissue as opposed to strong, solid bone and the softness of the growth plate can place children at risk of injury1,2. Weight-bearing exercise in which children carry their own bodyweight, such as running or doing push ups, has a positive impact on a child’s bone development. Boreham and McKay’s research findings3?support the concept that moderate to vigorous physical exercise, and a short bout of high-impact activity, such as jumping, promote bone growth in children. You should avoid prescribing repetitious, high-impact activities to children. Although jumping exercises are good for children’s bone growth, constant repetition of these activities will place strain on their growth plates. As a trainer you can promote healthy bone growth and minimise a child’s risk of growth plate injury by: varying training intensities by programming low, moderate and vigorous intensity exercises ensuring training sessions have a variety of activities that use different muscles and body parts (e.g. give children a skipping or jumping type exercise but then move them to an upper body exercise). If you suspect a child has sustained a bone injury it is important they see a doctor. If injuries are not treated properly, the bone may be prone to curvature or growth resul
