Can gymnastics stunt growth in kids? This is a worry many parents have. The direct answer, supported by extensive research, is no, gymnastics itself does not stunt a child’s growth. While it’s a common belief, often fueled by observing the smaller stature of some elite gymnasts, scientific studies show that participating in gymnastics does not negatively impact a child’s final adult height. The effect often attributed to gymnastics is usually related to other factors or is simply a misunderstanding of how growth works and why certain body types excel in the sport.
For years, a persistent myth has circulated that rigorous athletic training, especially gymnastics, can stop a child from growing properly. Parents might hesitate to enroll their children or pull them out of the sport based on this fear. Let’s look closely at where this idea comes from and what the real science says about the gymnastics effect on height.

Grasping the Myth’s Origin
Where did this idea that gymnastics stunts growth come from? It likely stems from simply seeing many top-level gymnasts who are shorter than average. People see this pattern and assume the sport caused them to be short.
Think about it. When you watch the Olympics, you see incredible athletes performing amazing feats on the beam, bars, and floor. Many, especially female gymnasts, are quite petite. It seems easy to connect their training with their size.
But this view misses a critical point: correlation is not causation. Just because two things appear together (gymnastics and shorter height) doesn’t mean one caused the other. Many things influence a child’s height, and gymnastics is just one activity they do.
The intense physical demands of competitive gymnastics might make people think it puts too much stress on a young body, somehow stopping it from reaching its full height. This is a common fear tied to the Impact of gymnastics on growth plates. We will look into this science soon.
Fathoming How Kids Grow
To really understand if gymnastics affects growth, we need to know how growth happens. Children grow mainly because of structures in their long bones called growth plates.
Growth plates are areas of soft cartilage near the ends of long bones (like those in the arms and legs). This cartilage hardens into bone over time, making the bone longer. This process continues until a child reaches skeletal maturity age. At this point, the growth plates close, and no more length can be added to the bones.
Growth is a complex process ruled mostly by genetics. A child’s final height is largely determined by the height of their parents and other family members. Hormones, like growth hormone and thyroid hormone, also play a big role.
Other things that affect growth include:
- Nutrition: Getting enough healthy food is key.
- Sleep: The body releases growth hormone during sleep.
- General Health: Chronic illness can affect growth.
- Stress: Both physical and emotional stress can potentially impact growth, though this link is complicated.
The idea behind the myth is that the stress or impact from gymnastics somehow damages or closes these growth plates early, stopping the bones from getting longer. Let’s see if this is true.
Interpreting the Impact of Gymnastics on Growth Plates
Concerns about the Impact of gymnastics on growth plates are central to the stunting myth. The fear is that the high forces, landings, and repetitive movements in gymnastics could harm these delicate areas of developing bone.
Growth plates can be injured. Fractures that go through a growth plate need careful medical attention because they could potentially affect future bone growth if not treated right. However, these are acute injuries, like breaking an arm.
The question is whether the regular stress of gymnastics training causes harm. While high-impact activities can put stress on bones, bone tissue is dynamic. It responds to stress. When stressed correctly, bones become stronger and denser. This is part of bone development in athletes.
Studies looking directly at the effect of gymnastics on growth plates have generally found:
- No evidence of premature closure: Regular gymnastics training does not typically cause growth plates to close earlier than they naturally would based on a child’s genetic timeline.
- Bone Strengthening: The weight-bearing nature of gymnastics is actually beneficial for bone health, leading to higher bone density compared to non-athletes. This reduces the risk of osteoporosis later in life.
- Potential for Injury: Like any sport, gymnastics carries a risk of injury. Repetitive stress or improper technique can lead to overuse injuries, such as stress fractures, which could affect growth plates if severe and not properly managed. But this is an injury issue, not an effect of the sport itself on normal growth.
- Natural Variation: Growth plates close at different ages for different people, regardless of sport. This timing is mostly genetic. Girls’ growth plates typically close earlier than boys’.
So, while acute injuries can happen and need care, the regular, healthy stress of gymnastics does not stunt growth by damaging growth plates. In fact, it often helps make bones stronger.
Scrutinizing Studies on Gymnastics Growth
Many Studies on gymnastics growth have been conducted over the years to try and settle this debate. Researchers have compared the growth patterns and final heights of gymnasts to:
- Children who don’t do gymnastics.
- Children who participate in other sports (like swimming, ballet, running).
- Their own genetic potential (based on parents’ height).
What have these studies found?
- Similar Final Height: Most studies conclude that rhythmic and artistic gymnasts, even those who train intensely from a young age, generally reach an adult height close to their genetically predicted height. Any differences found are often small and fall within the normal range of human height variation.
- Possible Temporary Delay in Maturation: Some research suggests that very intense training combined with inadequate nutrition (a critical point we’ll discuss more) might temporarily delay the onset of puberty and growth spurts in gymnasts. However, this delay does not typically result in a shorter final height. It often means the child has their growth spurt a little later than their peers. Once training volume decreases or nutrition improves, maturation usually catches up.
- Influence of Genetics: Studies repeatedly show that a child’s genetic background is the strongest predictor of their adult height, far outweighing the influence of gymnastics training.
- Selection Bias Confirmation: Many studies point to selection bias as a major reason why elite gymnasts are often shorter. Children with naturally smaller, more muscular builds may be better suited for the physical demands of high-level gymnastics (e.g., requiring high strength-to-weight ratio, quick rotations). These children may be more likely to continue in the sport at elite levels. Coaches might also unknowingly favor these body types during recruitment or training.
Here is a simplified look at what some studies might show (note: these are illustrative, specific numbers vary between studies):
| Study Type | Comparison Group | Common Finding | Key Factor Highlighted |
|---|---|---|---|
| Longitudinal Growth Study | Non-gymnasts | Gymnasts reach similar final height to peers, sometimes with delayed puberty. | Genetics, Potential for delayed maturation. |
| Cross-sectional Height Study | General population | Elite gymnasts are shorter on average than general population. | Selection bias. |
| Bone Density Study | Non-athletes, other athletes | Gymnasts often have higher bone density than non-athletes. | Beneficial impact of weight-bearing stress on bone. |
| Maturation Timing Study | Other sport athletes | Intense training might link to slightly later maturation, especially if underfed. | Training intensity, but heavily linked to Nutrition. |
The overall picture from Studies on gymnastics growth is clear: the sport itself doesn’t stop growth. While intense training can influence the timing of maturation, it doesn’t seem to affect the final outcome in terms of height. The observed shorter stature in elite gymnasts is more likely due to who stays in the sport than the sport’s effect on growth.
Weighing Competitive Gymnastics Health
Focusing on Competitive gymnastics health is important. While growth stunting is a myth, intense training does come with real health considerations that parents and coaches must manage.
High-level gymnastics demands many hours of training per week, starting at a young age. This level of commitment puts significant stress on a child’s body and mind.
Potential health concerns in competitive gymnastics include:
- Overuse Injuries: Repetitive movements can lead to stress fractures (especially in the spine, wrist, or foot), tendonitis, and joint pain. These are more common in sports requiring high force and repetition.
- Eating Disorders and Inadequate Nutrition: Pressure to maintain a certain body weight or composition, combined with high energy expenditure, can lead to inadequate calorie intake. This links strongly to potential growth and maturation issues.
- Menstrual Dysfunction: Inadequate energy intake relative to exercise can disrupt hormone production in female athletes, leading to irregular or absent periods (amenorrhea). This is a sign of a condition called Relative Energy Deficiency in Sport (RED-S), which can impact bone health and other body systems.
- Psychological Stress: The pressure to perform, fear of injury, and time demands can lead to anxiety, burnout, and other mental health challenges.
These are the real health issues to monitor in young, high-level gymnasts, not growth stunting from the exercise itself. Proper coaching, careful monitoring, a focus on balanced nutrition, and adequate rest are vital to minimizing these risks.
Stress, Energy, and Growth: Deciphering RED-S
We mentioned Relative Energy Deficiency in Sport (RED-S). This concept is crucial when discussing the potential impact of intense training on a child’s development. It’s often misinterpreted as the sport itself causing harm, when it’s actually a consequence of poor energy management within the sport.
RED-S happens when an athlete doesn’t consume enough calories to match the energy they burn through training and normal daily functions. This energy imbalance can affect many body systems, including:
- Metabolic rate
- Menstrual function (in females)
- Bone health
- Immune function
- Protein synthesis (muscle repair and growth)
- Cardiovascular health
In growing children and teenagers, inadequate energy availability due to RED-S can potentially delay:
- Puberty onset
- Skeletal maturation (reaching skeletal maturity age athletes)
- Linear growth (height gain)
Important distinction: This is not the exercise stopping growth. It is the lack of fuel to support both the high level of activity and the normal processes of growth and development. The body prioritizes energy for immediate survival and function over growth and reproduction when fuel is scarce.
So, if a young gymnast is training very hard but not eating enough to cover their energy needs plus the extra needs for growing, their growth or maturation might be temporarily delayed. But this delay is usually resolved once proper nutrition is restored. The final height is rarely affected, just the timing of the growth spurt.
This highlights the critical importance of Nutrition for young gymnasts. They need a balanced diet with enough calories, protein, healthy fats, carbohydrates, and micronutrients (like calcium and Vitamin D for bone development in athletes). Working with a sports dietitian can be very helpful for competitive young athletes.
The Puzzle of the Gymnast Physique
If gymnastics doesn’t stunt growth, why are elite gymnasts often shorter and more compact? This comes back to the idea of selection bias and biomechanics.
Certain body types have advantages in specific sports:
- Tall, lean bodies for basketball or rowing.
- Endurance-oriented bodies for distance running.
- Strong, compact, powerful bodies for weightlifting or gymnastics.
In gymnastics, skills often involve:
- Rotating quickly: Shorter limbs mean a smaller moment of inertia, allowing for faster rotations and twists.
- High strength-to-weight ratio: A lighter body for a given amount of strength makes skills like swinging on bars or performing aerial movements easier.
- Leverage: A more compact body can sometimes provide better leverage for specific movements.
Children who naturally have these physical traits may find gymnastics easier and more rewarding early on. They might progress faster and be more likely to continue training intensely and reach elite levels. Coaches, often unconsciously or consciously, may also identify and recruit athletes who show these physical predispositions.
Think of it this way: Many children start various sports. Those whose natural build and abilities fit a sport well are more likely to stick with it and excel. Over many years, this leads to a population of elite athletes in a sport who share certain physical characteristics, not because the sport created those characteristics, but because those characteristics helped them succeed in the sport.
So, the shorter stature often seen in elite gymnasts is less about the sport stopping growth and more about which body types are best suited to the sport at its highest levels. These athletes would likely have been shorter adults regardless of whether they chose gymnastics, swimming, or playing the flute.
Interpreting Early Gymnastics Training Development
The idea that Early gymnastics training development is somehow harmful is also linked to the growth myth. People worry that starting intense training too young is the problem.
However, starting gymnastics early can be very beneficial for many aspects of a child’s development:
- Motor Skills: Gymnastics builds amazing coordination, balance, agility, and body awareness. These are foundational motor skills useful in any sport or activity.
- Strength and Flexibility: Training develops significant strength and flexibility, essential for physical health.
- Discipline and Mental Toughness: The sport teaches dedication, perseverance, how to handle challenges, and setting goals.
- Bone Health: As discussed, weight-bearing exercise like gymnastics helps build strong bones during critical developmental years.
The key isn’t whether training starts early, but how that training is managed. Recreational gymnastics programs focus on fun, fitness, and basic skills. Competitive programs involve more hours and intensity.
Concerns arise when young athletes are pushed too hard, too soon, without adequate rest, nutrition, or proper technique guidance. This can lead to overuse injuries or contribute to the energy imbalance issue discussed earlier.
Responsible Early gymnastics training development focuses on:
- Age-appropriate skills and conditioning.
- Proper technique to prevent injury.
- Gradual increase in training volume and intensity.
- Listening to the child’s body and ensuring adequate rest and recovery.
- Prioritizing the child’s overall well-being and enjoyment of the sport over immediate performance outcomes.
When managed well, early gymnastics training contributes positively to a child’s physical literacy and overall health, without interfering with their natural growth potential.
Tracing Long Term Effects of Gymnastics
Looking at the Long term effects of gymnastics provides a broader perspective beyond the growth myth. What happens to gymnasts later in life?
Former gymnasts often carry forward many benefits:
- Physical Fitness: They maintain high levels of strength, flexibility, and balance.
- Bone Health: The high impact and weight-bearing stress during their youth contributes to strong bones, potentially reducing the risk of osteoporosis later in life.
- Discipline and Resilience: The mental skills learned in training often translate into success in academics and careers.
- Body Awareness: They typically have a deep understanding of their bodies and how they move.
In terms of height, most former gymnasts reach the height predicted by their genetics. Any temporary delays in maturation during their competitive years usually resolve, and they catch up in terms of growth spurts. The concern about stunted growth rarely manifests into a shorter adult height than they were genetically destined for.
The potential negative long term effects of gymnastics are more related to the cumulative impact of injuries or health issues experienced during their careers, particularly if not managed well. Chronic pain from old injuries or complications from past eating disorders are more realistic long-term concerns than stunted growth.
This reinforces the idea that focusing on Competitive gymnastics health throughout a child’s participation is key to ensuring the long-term benefits of the sport outweigh the risks.
Synthesizing the Evidence: The Real Picture
Pulling together the information from Studies on gymnastics growth, the science of growth, and factors like nutrition and genetics, the picture becomes clear.
The myth that gymnastics stunts growth is not supported by scientific evidence. Here’s a summary of why:
- Genetics are King: A child’s final height is overwhelmingly determined by their genetic makeup, inherited from their parents.
- Growth Plates are Resilient: While growth plates can be injured acutely, regular, properly managed gymnastics training does not cause them to close prematurely. It often strengthens bones.
- Selection Bias is Key: The shorter stature of many elite gymnasts is primarily due to the sport selecting for certain body types that have biomechanical advantages, not the sport causing shortness.
- Nutrition is Crucial: Temporary delays in maturation or growth are sometimes seen in highly intense training environments, but this is typically linked to insufficient calorie intake (RED-S), not the physical movements of gymnastics itself. Correcting nutritional deficiencies usually resolves the delay.
- Growth Catches Up: Even if maturation is slightly delayed, children typically reach their genetically determined adult height later.
Thinking about Growth spurts in gymnasts, they absolutely happen. Sometimes the timing might shift slightly, but the total amount of growth is usually unaffected by the sport itself.
Concerns about Skeletal maturity age athletes being affected by gymnastics should focus on ensuring athletes are getting adequate rest and nutrition to support healthy development, rather than fearing that the physical activity itself is damaging their bones’ ability to grow.
The Long term effects of gymnastics are generally positive, contributing to physical fitness, bone health, and mental toughness, assuming health is prioritized throughout training.
Key Takeaways for Parents and Coaches
For parents considering or currently involved in gymnastics for their children, and for coaches guiding young athletes, here are the key points to remember:
- Don’t Fear Stunting: The primary fear of gymnastics stopping a child’s growth is scientifically unfounded. Focus on the many benefits the sport offers.
- Prioritize Nutrition: Ensure young gymnasts consume enough calories and nutrients to support their high activity level plus their growth and development needs. Seek professional help from a sports dietitian if needed, especially for competitive athletes.
- Monitor for Health, Not Just Performance: Be aware of the signs of overtraining, overuse injuries, and potential issues like RED-S (fatigue, frequent illness, irregular/absent periods in girls, poor recovery).
- Choose a Reputable Program: Look for clubs and coaches who prioritize the long-term health and well-being of athletes, use age-appropriate training methods, and have a good understanding of child development.
- Listen to Your Child: Pay attention to their physical and emotional state. Ensure they are getting enough rest and are not experiencing excessive stress.
- Consult Professionals: If you have concerns about your child’s growth or health, consult with a pediatrician or a sports medicine specialist. They can evaluate your child’s growth pattern against their genetic potential.
Gymnastics is a fantastic sport that offers tremendous physical and mental benefits. By understanding the real factors that influence growth and focusing on holistic athlete health, parents and coaches can ensure that young gymnasts thrive and reach their full potential, both in and out of the gym, without worrying about unfounded myths about growth stunting.
Frequently Asked Questions (FAQ)
Q1: Is it true that elite gymnasts are short because the sport made them that way?
No, this is a common misunderstanding. Elite gymnasts are often shorter because individuals with smaller, more compact body types tend to have biomechanical advantages in the sport’s complex movements. This leads to a selection process where those with these natural traits are more likely to reach the elite level. The sport doesn’t cause the shortness; existing shortness is often an advantage in the sport.
Q2: Can hard physical training, like in gymnastics, damage a child’s growth plates?
Regular, properly managed training does not damage growth plates or cause them to close early. The weight-bearing stress of gymnastics actually helps strengthen bones. While severe acute injuries or chronic, unmanaged overuse injuries could potentially affect growth plates, this is not a typical outcome of healthy training.
Q3: Does gymnastics delay puberty or growth spurts?
Very intense training, especially when combined with insufficient calorie intake (Relative Energy Deficiency in Sport – RED-S), can sometimes temporarily delay puberty and growth spurts. However, this delay is usually resolved once training volume is managed and nutrition is adequate. It typically affects the timing of growth, not the final adult height, which remains primarily determined by genetics.
Q4: What are the real health risks for young competitive gymnasts if not growth stunting?
The main health risks in competitive gymnastics are overuse injuries (like stress fractures), issues related to inadequate nutrition and energy intake (like RED-S affecting bone health and hormonal function), and psychological stress. These require careful management through proper coaching, nutrition, rest, and monitoring.
Q5: Does early specialization in gymnastics affect growth?
Starting gymnastics early, in itself, does not stunt growth. The focus should be on the quality and appropriateness of the training. Age-appropriate training that prioritizes fun, skill development, and proper technique, along with adequate rest and nutrition, supports healthy development. Issues arise when training is too intense, too soon, without proper support for the child’s overall health needs.
Q6: Do gymnasts catch up on growth after they stop competing?
Yes, if there was any temporary delay in maturation or growth due to intense training and potential energy deficits, children typically experience their growth spurts and reach their genetically determined adult height after training volume decreases or nutrition improves.
Q7: Does nutrition play a role in gymnastics and growth?
Yes, a huge role. Adequate Nutrition for young gymnasts is critical. They need enough calories to fuel their demanding training and support the significant energy needs of growth and development. Insufficient energy intake is the primary reason why intense training might correlate with temporary growth delays in some cases, not the exercise itself. Proper nutrition supports Bone development in athletes and overall health.
