Why Are Gymnasts Short? This question has intrigued many, sparking debates about genetics, training, and the ideal body type for the sport. At WHY.EDU.VN, we delve into this topic, exploring the various factors that contribute to the seemingly shorter stature of gymnasts, offering a comprehensive analysis and debunking common myths. Discover the science behind the heights and physical attributes of gymnasts with insights into body composition and other relevant factors.
1. The Perception of Shortness in Gymnasts
It’s a common observation: gymnasts often appear shorter than the average person. This perception is fueled by comparing them to athletes in other sports, like basketball, where height is a distinct advantage. For example, Jordan Chiles, a U.S.A. gymnast stands at 5’5” while Kevin Durant, a basketball player, towers at 6’10”. However, is this perception accurate, and if so, what causes it?
2. Average Height vs. Gymnast Height
According to the Centers for Disease Control and Prevention (CDC), the average height for women in the United States is around 5’4″. Elite female gymnasts like Simone Biles, who is 4’8″, are significantly shorter than this average. The height difference may seem more pronounced because of the demanding physical requirements of gymnastics. But is this difference solely due to the sport, or are other factors at play?
3. The Self-Selection Theory
One leading theory is self-selection. Individuals with certain physical characteristics, such as shorter stature, may be more inclined to pursue gymnastics. Dr. Kevin Thomson, a physiologist, notes that being small aids rotational skills, such as somersaults. Similarly, gymnasts often have shorter arms and legs. This suggests that people with below-average height are drawn to gymnastics, potentially because they find they are more adept at the sport.
4. Genetic Predisposition
Genetic factors also play a significant role. Dr. Robert M. Malina, professor emeritus in the department of kinesiology at the University of Texas at Austin, suggests that many gymnasts are short because they have short parents. This indicates that genetics can be a determinant. This familial link is a strong indicator that genetics contribute significantly to the height of gymnasts.
5. The Impact of Gymnastics Training on Growth
While self-selection and genetics are important, the impact of gymnastics training on growth cannot be ignored. A 2000 study published in the Journal of Pediatrics found that gymnastics training can have some impact on growth. The study showed that active gymnasts had some deficits in leg length and sitting height. However, these deficits were not typically permanent. Once the gymnasts retired, they usually “caught up” on growth.
5.1. Details of the Study
The study involved 83 active female gymnasts, 42 retired gymnasts, and 154 healthy non-gymnasts. The results indicated that while active gymnasts showed growth deficits, retired gymnasts did not exhibit reduced stature in adulthood. This suggests that the impact of gymnastics on growth is temporary and reversible.
6. Gymnastics and Delayed Puberty
Elite gymnastics training is known to delay the onset of menstruation. A 1996 study found that only 20% of 13-year-old gymnasts had their first period compared to 95% of average 13-year-olds. Gymnasts are also at risk of exercise-induced amenorrhea, where the body stops menstruating due to low body weight and hormones released during exercise.
6.1. Long-Term Effects
The Journal of Pediatrics study also found that gymnasts did not experience any kind of menstrual dysfunction as adults due to their early-life training. This suggests that while there may be temporary delays, there are no long-term adverse effects on menstrual health.
7. Bone Age and Gymnastics
A 2002 study of 262 competitive gymnasts aged 13 to 23 found that gymnasts exhibited delayed bone age. Male gymnasts were one year behind their actual age, while female gymnasts were two years behind. Kostas Markou, the study leader, believed this was caused by training. The study also noted that many gymnasts “caught up” their delayed height and bone maturation after they retired.
7.1. The Timing of Exercise
Markou wrote, “The earlier the age of onset of exercise, the worse the effect on bone acquisition.” This indicates that starting gymnastics at a young age may have a more significant impact on bone development.
8. Conflicting Evidence on Growth Inhibition
A 2001 study published in the Clinical Journal of Sports Medicine found that a cause-effect relation between gymnastics training and inadequate growth of females has not been demonstrated. However, it also noted that there is conflicting evidence as to whether gymnasts really hit their full potential regarding height during the “catch-up” phase.
9. The Role of Nutrition
Inadequate nutrition during training years may also contribute to the small stature of gymnasts. NBC has reported that gymnasts typically try to get between 60% and 70% of their calories from proteins, with the rest from carbs and fats. While this diet has not been formally linked with stunted growth, eating disorders have historically been an issue within the women’s gymnastics community.
10. Advantages of Being Shorter in Gymnastics
Being shorter in gymnastics can be advantageous. Some data suggest that shorter elite female gymnasts are less likely to get injured. A systematic review of 22 studies published in British Journal of Sports Medicine in 2019 found that height and body mass were significant factors linked to gymnastic injuries. The higher the level of competition, the bigger the risk. Being short lowers the likelihood of gymnasts hurting themselves.
10.1. Mental Health Considerations
Another big potential injury risk is “life stress,” or what Simone Biles called “the twisties” when she pulled out of two 2021 Olympic gymnastic events for the sake of her mental health.
11. Injury Epidemiology and Risk Factors
A systematic review in the British Journal of Sports Medicine highlighted that injury epidemiology and risk factors in competitive artistic gymnasts are significantly influenced by height and body mass. Taller gymnasts face an elevated risk of injuries, especially at higher competition levels. This underscores the advantage of shorter stature in reducing the likelihood of physical harm in the sport.
11.1. Study Details
The review included 22 studies and emphasized that these factors must be considered to implement effective prevention strategies.
12. Addressing the Myth of Stunted Growth
While the training regimen of elite gymnasts seems to have some impact on their height, it’s likely less severe and far less permanent than the urban myths suggest. So, the idea that gymnasts would have grown to be a foot taller if they hadn’t spent all the time on the parallel bars is absolutely a myth.
13. The Impact on Rotational Performance
Research indicates that body size affects rotational performance in women’s gymnastics. A study by Ackland, Elliott, & Richards (2003) found that smaller body size is advantageous for rotational skills like somersaults. This is because a smaller body size reduces the moment of inertia, making rotations easier and faster.
13.1. Further Insights
The study also noted that gymnasts with shorter limbs tend to perform better in events requiring rapid rotations.
14. Physique and Body Composition
A systematic review by Bacciotti, Baxter-Jones, Gaya, & Maia (2017) explored the physique of elite female artistic gymnasts. The review highlighted that gymnasts typically have a lean body composition with a high muscle-to-fat ratio. This physique is beneficial for performing complex skills that require strength and agility.
14.1. Body Composition Details
The review noted that gymnasts usually have a lower percentage of body fat compared to the average population, aiding in their performance.
15. Gymnastics, Anorexia, and Menstrual Status
Bale, Doust, & Dawson (1996) examined the relationship between gymnastics, distance running, anorexia, body composition, and menstrual status. The study found that gymnasts and anorexics share similar body composition characteristics and menstrual irregularities. This underscores the importance of monitoring the nutritional status and menstrual health of gymnasts.
15.1. Monitoring Recommendations
Regular monitoring can help prevent potential health issues related to low body weight and hormonal imbalances.
16. The Influence of Selection Bias
Bass, Bradney, Pearce, Hendrich, Inge, Stuckey, Lo, & Seeman (2000) investigated the influence of selection bias on leg length and the duration of training on trunk length in short stature and delayed puberty in gymnasts. The study found that selection bias plays a role in the short stature of gymnasts, as individuals with shorter legs are more likely to be selected for the sport.
16.1. Training Duration Impact
The study also found that the duration of training had an impact on trunk length, with longer training periods associated with shorter trunk length.
17. Growth Patterns in Gymnasts
Georgopoulos, Theodoropoulou, Leglise, Vagenakis, & Markou (2004) studied growth and skeletal maturation in male and female artistic gymnasts. The study found that gymnasts experience delayed growth and skeletal maturation compared to their non-gymnast peers. This delay is more pronounced in female gymnasts.
17.1. Skeletal Maturation Details
The study suggested that the intense physical demands of gymnastics training may contribute to these delays.
18. What Does This Mean for Aspiring Gymnasts?
Understanding the science behind the height of gymnasts can empower aspiring athletes and their parents to make informed decisions about their training and health. While genetics and self-selection play significant roles, the impact of training and nutrition should not be overlooked.
18.1 Balancing Training and Health
It’s crucial for young gymnasts to maintain a balanced diet and undergo regular health check-ups to ensure they are growing and developing properly. Parents and coaches should also be aware of the potential risks of overtraining and eating disorders and take steps to prevent them.
