Does Gymnastics Stunt Your Children's Growth? Here Are The Scientific Answers
Gymnastics is an incredible sport that combines strength, flexibility, and discipline. However, a long-standing myth persists: does gymnastics stunt your growth? Many parents and aspiring gymnasts wonder if participating in this sport could affect a child’s height or overall development.
The sight of elite gymnasts who are often shorter than average raises questions about whether gymnastics causes stunted growth or if there’s more to the story. In this article, we’ll explore the science behind this perception, why shorter stature is advantageous in gymnastics, and whether the sport poses any health risks.
Why Do Gymnasts Tend to Be Shorter?
The misconception that gymnastics stunts growth likely stems from observing that many successful gymnasts are short. This isn’t because the sport stunts growth but because shorter athletes have a natural advantage in gymnastics. Factors contributing to this include:
A. Weight-Bearing Advantage
Gymnastics is a weight-bearing sport, which means that athletes must support their own body weight during various routines, such as flips, handstands, and other acrobatic movements.
Shorter athletes have an advantage in this sport because they carry less weight, making it easier to execute complex movements and maintain balance. Less weight also reduces the risk of injury and allows for more fluidity and agility during performances.
B. Early Start in Training
Many gymnasts begin their training at a very young age, often around 3-6 years old. During this time, children's bodies are still growing and developing.
When children are exposed to intense physical training at an early stage, it can impact their growth trajectory. For instance, rigorous training may influence the timing of growth spurts, potentially leading to a shorter final height compared to peers who started sports or physical activities later.
However, this early exposure to gymnastics can also result in the development of a strong and agile body, even if the gymnast ends up being shorter in stature.
C. Genetic Factors and Body Type
Gymnastics tends to favor certain body types that are more suited to the demands of the sport.
Shorter stature and a compact build are often seen as more advantageous in gymnastics because they allow for better control, flexibility, and quicker movements.
These physical traits often align with the natural body types of many elite gymnasts, and while genetics play a role in height, the sport’s physical demands often complement these body types.
Why Is It Better for Gymnasts to Be Short?
In gymnastics, physics plays a key role in performance, particularly the concept of inertia, which refers to the resistance an object has to start rotating. For a gymnast, this means that the closer their mass is to their axis of rotation, the easier it is to rotate quickly.
Shorter gymnasts, with less mass and a more compact body, are able to tuck and rotate faster during acrobatic moves like somersaults. This gives them a significant advantage in executing rapid rotations.
Additionally, a shorter gymnast has a lower center of gravity, which enhances their stability during landings. With a more stable base of support, they can maintain better control and reduce wobbling upon landing, making them more efficient and precise in their movements.
This combination of speed and stability makes being shorter a distinct advantage in the sport of gymnastics.
Does Being a Gymnast Cause Any Health Problems?
While gymnastics offers numerous physical benefits, such as strength, flexibility, and coordination, the sport does come with some potential health risks, especially when practiced intensely over long periods. Here are a few common health concerns associated with being a gymnast:
1. Injury Risk and Height
Shorter gymnasts may have a lower risk of injury. A 2019 systematic review published in the British Journal of Sports Medicine found that height and body mass were significant factors linked to gymnastic injuries, with shorter gymnasts less likely to be injured.
Additionally, the higher the competition level, the greater the risk. Therefore, being shorter may offer some protection against injury in gymnastics.
2. Mental Health and Stress
Gymnastics, particularly at the elite level, can lead to mental health challenges, such as "life stress," which can manifest in issues like the "twisties" (a term coined by Simone Biles to describe disorientation during routines).
These mental health struggles can lead gymnasts to take breaks from competition, as seen in Biles' 2021 Olympic withdrawal. This highlights the importance of mental well-being alongside physical training in gymnastics.
3. Delayed Menstruation and Exercise-Induced Amenorrhea
Elite gymnastics training can delay the onset of menstruation, particularly for female gymnasts. A 1996 study showed that only 20% of 13-year-old gymnasts had started their period compared to 95% of non-gymnasts.
This delay, sometimes leading to exercise-induced amenorrhea (absence of menstruation due to low body weight and intense physical training), can affect hormonal balance.
However, studies suggest that this delay does not lead to long-term menstrual dysfunction once gymnasts reach adulthood.
4. Delayed Bone Growth
Gymnasts may experience delayed bone age, which means their bones develop slower than their chronological age.
A 2002 study found that male gymnasts were about one year behind their actual age in terms of bone growth, while female gymnasts were about two years behind. This delay is believed to result from early, intense training.
However, many gymnasts "catch up" in height and bone maturation after they retire from competitive gymnastics, suggesting the effects are not permanent.
5. Potential Effects on Growth and Nutrition
While gymnastics training may impact height and bone development, a 2001 study found no direct cause-effect relationship between gymnastics training and stunted growth. Instead, inadequate nutrition during training years, such as a high-protein, low-calorie diet, may be more influential.
While gymnasts typically consume a balanced diet, eating disorders within the gymnastics community have historically contributed to growth concerns.
So, Does Gymnastics Stunt Your Growth?
The belief that gymnastics stunts children's growth is a myth. While gymnasts may be shorter than average, this is due to natural selection in the sport and temporary growth delays, not permanent stunting.
With proper nutrition, rest, and coaching, gymnastics is a safe and beneficial sport that builds strength, flexibility, and discipline.
