Imaging of triathlon injuries

Area of Science:

• Sports Medicine
• Orthopedics
• Exercise Physiology

Background:

• Triathletes are susceptible to a high incidence of overuse injuries across all three disciplines: swimming, cycling, and running.
• Common swimming-related complaints include rotator cuff tendinitis, though MRI findings for tendinopathy and tears are similar in painful and non-painful shoulders.
• Cycling and running present distinct injury patterns, affecting the knee, spine, and lower extremities.

Purpose of the Study:

• To identify and characterize the common injuries sustained by triathletes.
• To differentiate injury patterns across swimming, cycling, and running disciplines within triathlon.
• To understand the exacerbating factors of injuries in triathletes.

Main Methods:

• Review of injury epidemiology in the triathlon population.
• Analysis of common overuse injuries reported in swimming, cycling, and running.
• Correlation of symptoms with diagnostic imaging findings where applicable.

Main Results:

• Running is the most frequent cause of injury, often leading to the cessation of training or competition.
• Cycling injuries commonly affect the knee (patellar tendinosis, IT band syndrome, patellofemoral stress syndrome), Achilles tendon, and spine (cervical and lumbar).
• Swimming injuries primarily involve the rotator cuff, but MRI results show comparable rates of tendinopathy and tears regardless of shoulder pain presence.

Conclusions:

• Overuse injuries are prevalent in triathletes, with running posing the greatest risk.
• Specific injury sites and conditions are associated with each sport, though injuries can be exacerbated by other disciplines.
• While rotator cuff tendinitis is common in swimming, its severity may not directly correlate with MRI-detected tears or tendinopathy.
