BACKGROUND The authors previously identified a significant association between lumbar disc degeneration (LDDG) and cartilage intermediate layer protein (CILP) single nucleotide polymorphism (SNP) in collegiate male judokas. HYPOTHESIS A significant association between LDDG and the CILP SNP is observed in Japanese collegiate athletes. STUDY DESIGN(More)
Several studies have shown a higher prevalence of radiological abnormalities among gymnasts. However, the types of radiological abnormalities associated with low back pain (LBP) have not been clarified. The hypothesis was that significant relationships between radiological abnormalities and LBP may be revealed by discriminating between the types of MRI(More)
BACKGROUND Magnetic resonance imaging (MRI) studies have shown that gymnasts have a high prevalence of radiological abnormalities, such as intervertebral disk degeneration (IDD) and anterior limbus vertebra (ALV). These 2 abnormalities may coexist at the same spinal level. However, the relationship between IDD and ALV remains unclear. HYPOTHESIS A(More)
Several studies have shown higher frequencies of radiological abnormalities among gymnasts. Recently, the gene encoding the α1 chain of type XI collagen, (COL11A1) (rs 1676486), was associated with lumbar disc herniation in the Japanese population. We hypothesized that there was a significant relationship between abnormal magnetic resonance imaging (MRI)(More)
