History of Multiple Allergies and Gradual Onset Running-Related Injuries in Distance Runners: SAFER XXXV

Area of Science:

• Sports Medicine
• Allergology
• Epidemiology

Background:

• Gradual onset running-related injuries (GORRIs) are common among runners.
• The relationship between allergies and GORRIs is not well-established.

Purpose of the Study:

• To investigate the association between allergies (single, multiple, and medication use) and the incidence of GORRIs in marathon runners.

Main Methods:

• A cross-sectional study analyzed data from 76,654 participants in the Two Oceans Marathons (2012-2015).
• Online screening questionnaires collected data on history of allergies and GORRIs (muscle, tendon) in the past 12 months.

Main Results:

• A history of any allergy, multiple allergies (animal, plant, medication), and allergy medication use were significantly associated with GORRIs.
• The risk of GORRIs increased with the number of allergy categories reported, indicating a cumulative effect.
• Allergy history and medication use were linked to both muscle and tendon injuries.

Conclusions:

• Allergies and allergy medication use are significant risk factors for GORRIs.
• A cumulative risk effect was observed with multiple allergies.
• Further research is needed to elucidate the mechanisms linking allergies and GORRIs.
