Growth spurts can temporarily affect coordination, balance, strength, confidence, and injury risk in teen athletes. Parents and coaches should treat awkward phases as normal development, not laziness or a permanent loss of ability.
TL;DR: The article gives practical steps, common mistakes, and safe ways to apply the topic without overcomplicating it.
What changes during a growth phase
Adolescence can bring rapid changes in height, limb length, body mass, hormones, strength, and body awareness. A player who looked smooth in one season may look clumsy the next because the body’s proportions changed faster than coordination adapted.
Current sports-medicine research, including a British Journal of Sports Medicine review on growth, maturation, and injury in youth athletes, links growth and maturation with changes in injury risk and performance demands. The lesson for adults is not to panic. It is to adjust expectations and training.
Growth is not evenly timed. Two athletes of the same age can be at different biological stages. That is why age-group comparisons can be misleading.
Signs parents and coaches may notice
Common signs include mistimed jumps, awkward running mechanics, reduced balance, slower change of direction, sudden tightness, new soreness, or frustration with skills that used to feel easy. Some athletes also become self-conscious about body changes, especially when peers develop earlier or later.
These signs do not automatically mean injury or poor effort. They are clues to watch training load, movement quality, sleep, nutrition, and emotional confidence.
A coach running evaluations should account for this. The article on tryouts that evaluate more than raw talent explains why coachability, learning speed, communication, and role fit should sit beside current physical polish.
Training adjustments that help
Reduce unnecessary volume when movement quality drops. Use more coordination ladders, balance drills, landing practice, low-load strength work, and technique resets. Keep the athlete active, but avoid treating every awkward phase with more intensity.
The NSCA’s long-term athletic development position statement supports developmentally appropriate training across childhood and adolescence. That means athletes can build strength and skill, but the plan should respect maturation, recovery, and quality coaching.

Parents can help by watching patterns. One sore day is common. Repeated pain, limping, sharp discomfort, or changes that do not improve should prompt a conversation with a qualified health professional.
Communication that protects confidence
Teen athletes often hear adults say they look lazy, slow, or uncoordinated. That can hurt confidence when the athlete is already trying to understand a changing body. Use language that separates the person from the phase: your timing is changing right now, so we will rebuild it step by step.
Ask athletes what feels different. Some may report tightness, fatigue, or trouble judging distance. Others may not have words for it yet. Calm questions help adults adjust the plan without embarrassing the athlete.
Link progress to controllable habits: warm-up quality, sleep routine, fueling, mobility, balance work, and attention during technique drills. Avoid constant comparison with teammates who may be at a different stage.
When to be more cautious
Take repeated pain seriously, especially around growth plates, knees, heels, hips, and ankles. Also watch for sudden drops in energy, recurring injuries, or fear of movement. A qualified medical professional should evaluate symptoms that persist or worsen.
Strength and conditioning should be supervised and progressive. The goal is not to stop teen athletes from training; it is to train them in a way that supports the body they have now.
For athletes who are also increasing conditioning volume, read conditioning mistakes that leave players tired but not fitter before adding more hard sessions during a growth phase.
The balanced view adults should keep
Growth spurts can be frustrating, but they are also part of athlete development. A temporary coordination dip can become a chance to rebuild technique, improve body control, and strengthen communication between athletes, coaches, and parents.
Support the athlete with patience, adjusted load, and clear feedback. The aim is long-term progress, not forcing a developing body to look finished before it is ready.
