Children and teenagers grow and develop at different rates. During childhood and adolescence the body undergoes major changes in height, strength, coordination and hormonal development.
These changes are part of the normal process of growth and maturation. Understanding how this process works can help parents, coaches and healthcare professionals support young athletes safely during sport.
Because the body is constantly developing, the physical demands placed on a young athlete may need to change over time.
What Is Growth and Maturation?
Growth refers to the physical increase in body size, such as height, weight and bone length.
Maturation describes the biological process through which the body develops toward adulthood. This includes changes in hormones, muscle development, coordination and physical capability.
During childhood and adolescence these processes occur at different speeds in different individuals.
Why Children Develop at Different Rates
Young people of the same age can appear very different physically. Some may grow earlier, while others develop later. This is because biological maturation does not occur at exactly the same time for everyone.
During puberty, hormones stimulate rapid changes in body size and composition. These changes often occur earlier in girls than in boys, although the timing varies widely between individuals.
Because of these differences, athletes in the same age group may have very different physical abilities.
The Adolescent Growth Spurt
One of the most significant periods of development is the adolescent growth spurt. During this stage, children may grow rapidly in height over a relatively short period of time.
Rapid growth can temporarily affect:
- Coordination
- Balance
- Flexibility
- Strength
These temporary changes can influence athletic performance and may also increase injury risk during sport.
How Growth and Maturation Affect Sport Performance
Growth and maturation influence many aspects of physical performance.
As children mature, they typically develop:
- Greater strength
- Increased power
- Improved speed
- Better coordination
Early-maturing athletes may temporarily have advantages in size, strength or speed compared with peers who mature later.
However, these differences often reduce as athletes reach full maturity.
Growth and Injury Risk
Periods of rapid growth can increase injury risk in young athletes.
When bones grow quickly, muscles and tendons may take time to adapt. This temporary imbalance can increase tension on certain areas of the body.
Research shows that growth and maturation are linked to injury patterns in youth athletes, particularly during growth spurts.
Many growth-related injuries occur when the physical demands placed on the body exceed what developing tissues can currently tolerate.
Monitoring Growth in Young Athletes
Tracking growth can help identify periods where athletes may be more vulnerable to injury.
Some useful strategies include:
- Measuring height regularly
- Monitoring training loads
- Adjusting training during growth spurts
- Encouraging strength and conditioning
Recognising periods of rapid growth allows training programs to be adapted accordingly.
Supporting Healthy Development
Healthy growth and maturation depend on several important lifestyle factors.
Young athletes benefit from:
- Balanced nutrition
- Adequate sleep
- Regular physical activity
- Appropriate recovery between training sessions
Supporting these factors helps the body adapt to sport and develop safely.
Why Long-Term Development Matters
Young athletes should be encouraged to develop gradually over time.
Focusing on long-term development rather than early performance can help reduce injury risk and support lifelong participation in sport. Encouraging a variety of physical activities during childhood helps build fundamental movement skills and physical confidence.
When to Seek Professional Advice
If a young athlete experiences persistent pain, fatigue or difficulty coping with training, it may be helpful to seek professional advice. Healthcare professionals experienced in youth sport can assess whether symptoms may be related to growth, training load or injury.

Frequently Asked Questions About Growth and Maturation
What is the difference between growth and maturation?
Growth refers to physical increases in body size, while maturation describes the biological process of developing toward adulthood.
Why do children grow at different rates?
The timing of puberty and hormonal changes varies between individuals, which means children of the same age can develop at very different rates.
Does growth increase injury risk?
Rapid growth can temporarily increase injury risk because bones may grow faster than muscles and tendons can adapt.
How can coaches support athletes during growth spurts?
Monitoring growth, adjusting training loads and focusing on strength and movement skills can help support young athletes during periods of rapid development.
Should young athletes specialise in one sport early?
Participating in multiple sports during childhood helps develop a broader range of movement skills and may reduce injury risk compared with early specialisation.
