Our body’s capacity to endure in a sport and the inflammatory processes that this exercise exerts over it depends on the synthesis and regulation of pro-inflammatory cytokines. The mixture of genetics and slowly building up training stamina are vital determinants that serve as the foundation for an athlete’s performance. Therefore, detecting specific gene variations of encoding proteins for pro-inflammatory cytokines is a cornerstone for functional medicine assessment in athletes.

Inflammatory response to injury
During ligament and tendon injuries, pro-inflammatory mediators such as cytokines and interleukins become upregulated. Exercise is a systematic movement, and as such, it may exert repetitive mechanical loading in connective tissue cells resulting in cytokine upregulation. Therefore, an exacerbated inflammatory response may result in an increased recovery time after an injury or a training session. In a highly competitive world, these inflammatory responses can play a crucial role in determining an athlete’s performance or endurance.
Nowadays, SNP detection technology, screening, and research on specific sports or joint injuries provide a great insight into the maintenance of stamina and performance. Specific genetic variants associate with faster connective tissue recovery, serving as an excellent diagnostic tool to build a proper recovery or nutritional treatment.
The inflammatory response due to an injury initiates with interleukin-1B (IL-1B) upregulation, and the IL1B human gene encodes this cytokine. The macrophages present in the injured tissues produce IL-1B, which activates other pro-inflammatory cytokines like interleukin-6 (IL-6). This synthesis and cascade reaction is present after tendon and ligament injuries by fibroblasts.
In sports, IL-6, encoded by the IL-6 gene, expression increases in tendon loading, such as stretching of tendon fibroblasts and pathological conditions. Furthermore, an IL-6 increase results in elevated inflammation, apoptosis, and bone reabsorption. However, IL-6’s depends on its binding receptor, interleukin 6 receptor (IL-6R), to exert its pro-inflammatory effects.
Hypothesis supports the idea that polymorphisms of these specific encoding genes reflect an elevated tendency to ligament ruptures.
Clinical applications: Injury of the Anterior Cruciate Ligament
As genetic research evolves, new associations between gene variants and musculoskeletal soft tissue conditions become more evident. In this athletic population, the detection of specific gene variants can affect the mechanical function and structure of their connective tissue and muscle, reflecting poor performance or predisposition to injury.
Inflammation that rises in the injury’s presence is needed to restore and remove offending factors, ultimately leading to recovery. However, this balanced upkeep between the degradation and synthesis is essential to withstand the mechanical loads induced by exercise. Therefore, polymorphism detection of inflammatory gene variants, such as IL-IB, IL-6, and IL-6R, can be helpful in injury prevention and athletic training and recovery.
A Polish study explored four polymorphisms (IL1B rs16944 and rs1143627, IL6 rs1800795 and IL6R rs2228145) within three candidate genes: IL-1Î², IL-6, IL-6R for association with ACL injury risk. This study found a significant association between IL6 rs1800795 and the tendency to develop ACL injury or rupture. These authors compared their findings to previous reports and determined that the CC genotype in this encoding gene is potentially protective against the ACL condition.
Also, they reported an association between the IL-6 gene CC genotype and reduced risk of osteoporosis. On the other hand, homozygous for the C allele postmenopausal women have low serum levels of type 1 collagen, an important marker of bone reabsorption. Elevated serum levels of C-reactive protein are a consistent finding in those individuals with G/C variants in this same gene.
How to measure inflammatory genes:
DNA analysis has become easier and accessible to those patients looking for an in-depth genetic assessment. Companies like dnalife provide a wide array of tests to prevent musculoskeletal injuries.
Inflammatory processes initiate a healing response. However, when this response is exacerbated, soft tissue ruptures or injuries can become difficult to treat or recover. SNP detection technology shines a light on this topic and provides a proper treatment to maintain and support athletic performance. Nevertheless, as these genes encode inflammatory markers, they may serve as preventive markers for those patients with a family history of soft tissue disease. – Ana Paola RodrÃguez Arciniega, MS
