Sports injuries, including muscle strains, tendon tears, and joint dislocations, are common among professional athletes and can be both physically and mentally debilitating. These injuries not only impact athletes' careers but can also lead to permanent disabilities, limiting their future prospects. While the role of connective tissue structure in sports injuries is well-recognized, the influence of genetic makeup on an individual's susceptibility to such injuries remains a subject of exploration.
This study aims to investigate the genetic variations in Collagen V genes, specifically COL5A1, COL5A2, and COL5A3, and their potential association with the prevalence of sports injuries among professional athletes.
The hypothesis driving this research is that specific genetic variants in these collagen genes may render individuals more susceptible to sports-related injuries.
Collagen proteins are vital constituents of the extracellular matrix in various tissues, ensuring structural integrity and stability. Among the 28 known types of collagen, the major fibrillar collagens, such as Types I, II, and III, play a central role in tissue structure.

Minor fibrillar collagens, including Type V, are present in smaller quantities and often complement the major collagen types. Collagen V is a heterotrimeric protein composed of three different subunits, 𝛼1, 𝛼2, and 𝛼3, each encoded by separate genes, COL5A1, COL5A2, and COL5A3, respectively. These genes exhibit numerous polymorphisms, introducing variations between individuals and modifying the properties of collagen V.
Given the pervasive presence of collagen proteins in the human body, genetic variations in these genes can induce alterations in an individual's characteristics, affecting traits such as eye shape, scarring, and susceptibility to genetic diseases.
For instance, defects in collagen V structure are associated with hereditary diseases like Ehlers-Danlos syndrome (EDS), which can lead to connective tissue abnormalities, joint hypermobility, and skin hyperextensibility.
Considering the critical role of collagens in connective tissues, it is reasonable to hypothesize that genetic variations in collagen genes may also influence the propensity to sustain sports injuries. Understanding these genetic associations could contribute to personalized injury prevention programs for professional athletes in the future.
Therefore, this study aims to investigate whether certain genetic variants in COL5A1, COL5A2, and COL5A3 are linked to an increased vulnerability to sports injuries. By analyzing the genetic associations related to sports injuries, we can gain insights that may aid in the development of tailored injury prevention strategies for athletes.
The primary research question addressed in this study is: "How are the variations in Type V Collagen genes COL5A1, COL5A2, and COL5A3 related to the prevalence of sports injuries amongst professional athletes?"
Additional research questions include:
This research seeks to address these questions by analyzing the genetic associations related to sports injuries among professional athletes.
A cohort of 129 professional Estonian athletes, aged 18 to 50, participated in this study. They engaged in national and international professional sports, with high training loads and physical stress. 76 practiced endurance sports, and 53 strength sports. Out of these, 48 had injuries (ACL rupture, Achilles tendinopathy, or hamstring strain), while 81 remained injury-free. Athletes with injuries comprised the test group, and the injury-free athletes formed the control group.
To analyze collagen V gene variations, single nucleotide polymorphisms (SNPs) were genotyped. SNPs represent common genetic variations in humans, with differences in DNA nucleotides (Adenine, Thymine, Cytosine, Guanine). The SNP of collagen V gene served as the independent variable, while injury status was the dependent variable.
Data, obtained with ethical approval, included clinical information, injuries, and genotypes. Genotypes for COL5A1, COL5A2, and COL5A3 were used, processed, and grouped by injury status. Chi-squared tests were conducted to assess SNP frequency differences' significance.
Data analysis, conducted in Excel, included 20 randomly selected SNPs (Table 1). Chi-Squared tests identified 5 statistically significant SNPs: rs67844351, rs8113693, rs3745591, rs3745598, rs35678764. These SNPs were further investigated, with rs67844351 from COL5A1 and the rest from COL5A3.
| SNP | Allele | Injured Athletes (%) | Not Injured Athletes (%) |
|---|---|---|---|
| rs67844351 | CTAT | 42% | 28% |
| rs8113693 | G | 41% | 25% |
| rs3745591 | C | 41% | 24% |
| rs3745598 | G | 49% | 36% |
| rs35678764 | C | 77% | 63% |
This study analyzed genetic variations in Collagen V genes. Statistically significant SNPs were found in COL5A3 and COL5A1. Four significant SNPs belonged to COL5A3, while one was from COL5A1. Thus, COL5A3 had the most impact on professional athletes' sports injuries.
Comparing alleles' impact on injury likelihood, rs67844351 in COL5A1 showed the presence of the CTAT allele was 33% more common in injured athletes, suggesting its association with higher injury susceptibility.
SNPs rs8113693 and rs3745591 from COL5A3 displayed the most significant differences. rs8113693 showed a 39% higher presence of the T allele in injured athletes, while rs3745591 had a 41% higher presence of the C allele. Both alleles increase the risk of sports injuries.
Lastly, rs3745598 from COL5A3 had a smaller difference in allele frequencies, with a 27% higher presence of the G allele among injured athletes. These findings indicate a potential genetic predisposition to sports injuries.
In conclusion, genetic variations in Collagen V genes, especially in COL5A3 and COL5A1, are associated with sports injury susceptibility among professional athletes. The presence of specific alleles increases the likelihood of obtaining sports injuries, providing valuable insights for personalized injury prevention strategies.
This study investigated the relationship between genetic variations in Collagen V genes, specifically COL5A1, COL5A2, and COL5A3, and the prevalence of sports injuries among professional athletes. The research aimed to address the hypothesis that certain genetic variants in these collagen genes may render individuals more susceptible to sports-related injuries. Through comprehensive data analysis, this study has shed light on the genetic factors contributing to the risk of sports injuries among athletes.
The findings of this study highlight several key points:
In conclusion, this study contributes valuable insights into the genetics of sports injuries among professional athletes. The significance of specific genetic variants within Collagen V genes underscores the importance of considering genetic factors in injury prevention and athlete well-being. As we move forward, further research and the integration of genetic information into sports medicine can lead to more effective strategies for safeguarding the health and careers of athletes.
