PURPOSE: Cycling is widely practiced as a mode of transportation, a leisurely pursuit and a
competitive sport. Approximately half of cyclists experience low back pain. Yet, there has been
limited study of spine tissue adaptations due to cycling.
METHODS: To investigate potential risk factors for spinal pain, we compared 18 high-volume
cyclists (>150 km per week for ³5 years) to 18 height-matched non-sporting referents.
Participants had no history of spinal pathology. Magnetic resonance imaging was used to
quantify intervertebral disc (IVD) morphology and hydration; and psoas, erector spinae,
quadratus lumborum and multifidus muscle size and fat content. Endurance of trunk muscles
(flexors and extensors) were measured and physical activity levels assessed objectively using
accelerometry.
RESULTS: Cyclists IVD showed prolonged T2-time (+10.0(17.3)%; p=0.021), implying better
IVD hydration and glycosaminoglycan content, compared to referents. Lower thoracic and
upper lumbar IVD T2 time were longer in cyclists (p≤0.029) but not at the lower lumbar spine.
T2-time differences were larger in the nucleus pulposus compared to the annulus fibrosus.
Cyclists showed larger psoas muscles with less fat content compared to referents. Cyclists also
exhibited longer isometric trunk endurance times (p≤0.036) and higher physical activity levels
(osteogenic index, p=0.038).
CONCLUSION: Despite previous studies reporting higher than average prevalence of back
pain in cyclists, the high-volume road cyclists in our cohort showed no anatomical or functional
deficiency in spinal structures. In contrast, we found evidence for beneficial adaptations to the
intervertebral discs and psoas muscles in high-volume cyclists compared to referents. These
data support the notion that cycling is not detrimental to the spine; rather, in contrast, may be
associated with beneficial changes at the spine.

Podstawski, Robert; Borysławski, Krzysztof; Clark, Cain C. T.; Laukkanen, Jari A.; Gronek, Piotr (Montenegrin Sports Academy, 2020)This study aimed to determine the effect of 16 minutes of thermal stress followed by 2 minutes of cold water immersion on the physiological parameters of fifty-five sedentary men (mean age 20.15±1.30 years), who were exposed ... -
Exercise for the intervertebral disc : a 6-month randomised controlled trial in chronic low back pain
Owen, Patrick J.; Miller, Clint T.; Rantalainen, Timo; Simson, Katherine J.; Connell, David; Hahne, Andrew J.; Trudel, Guy; Ford, Jon J.; Belavy, Daniel L. (Springer, 2020)Background context Muscle, bone and tendon respond anabolically to mechanical forces. Whether the intervertebral disc (IVD) can benefit from exercise is unclear. Purpose To examine whether exercise can beneficially ... -
Mechanical loading influences the lumbar intervertebral disc : A cross‐sectional study in 308 athletes and 71 controls
Owen, Patrick J; Hangai, Mika; Kaneoka, Koji; Rantalainen, Timo; Belavy, Daniel L. (Wiley, 2021)There is evidence in animal populations that loading and exercise can positively impact the intervertebral disc (IVD). However, there is a paucity of information in humans. We examined the lumbar IVDs in 308 young athletes ... -
Characterization of Intervertebral Disc Changes in Asymptomatic Individuals with Distinct Physical Activity Histories Using Three Different Quantitative MRI Techniques

(MDPI, 2020)(1) Background: Assessments of intervertebral disc (IVD) changes, and IVD tissue adaptations due to physical activity, for example, remains challenging. Newer magnetic resonance imaging techniques can quantify detailed ...
