Home Message: Survey participants who reported frequently running and swimming had
greater signs of lumbar disc degeneration than those participants who were
inactive in those sports.

Greater involvement in sports is a risk
factor for long-term degeneration of lumbar intervertebral discs. Understanding
the impact of sport involvement in lumbar disc degeneration will help
clinicians develop strategies to mitigate the impact of sport on lumbar disc
degeneration. Therefore, Takatalo and colleagues evaluated the association between
sport involvement and lumbar disc degeneration in an exploratory study. A total
of 9,479 children were identified via the Northern Finland Birth Cohort
(expected birth between July 1985 and June 1986). Participants received 2
surveys of sporting activity when they were 16 and 18 years old respectively. The
authors invited participants who responded to both surveys (1987 participants) to
a physical examination and magnetic resonance imaging. A total of 558
participants completed both surveys and completed the magnetic resonance imaging.
Magnetic resonance images were grades on a scale of grades 0-5 (0-2 = normal,
3-5 = LDD) by 2 blinded musculoskeletal radiologists. Researchers controlled
for body mass index, lifestyle factors, other sports, and socioeconomic status.
Overall, 301 (54%) participants were classified with lumbar disc degeneration. Highly
active runners/joggers (> 2 times/week) were 3 more likely to have greater
lumbar disc degeneration than inactive participants. Furthermore, highly active
swimmers were 5 more likely to have greater lumbar disc degeneration than
inactive participants. Skaters were less likely to have lumbar disc

We can take from this study that some
activities (e.g., highly active running and swimming) may have detrimental
effects on lumbar discs, while other activities may be protective (skating). It
should be noted that this study was exploratory in nature and did not attempt
to quantify how much activity would elicit these effects. This limits clinicians
from using the current study to influence clinical decision making or
counseling. This dose-response association should be looked at further to
better help clinicians, parents and athletes fully grasp the impact that
certain sports have on lumbar disc degeneration. In the meantime, clinicians
should take note that some athletes may be a greater risk for lumbar disc
degeneration before 20 years of age. It may be beneficial to ensure these
athletes are participating in strengthening programs that may help reduce their
chances of developing low back pain. We may need low back pain prevention
programs for athletes in certain sports much like how we’ve deployed lower
extremity injury prevention programs.

Questions for Discussion: Have you encountered patients
in this age range with
disc degeneration
? If so, do you believe their activity was a factor in lumbar disc degeneration development?
