What are the management options for urinary incontinence (UI) associated with marathon running?

Management of Urinary Incontinence in Marathon Runners

For marathon runners experiencing urinary incontinence, pelvic floor muscle training (PFMT) should be the first-line treatment, as it has been shown to improve continence rates with minimal side effects and is strongly recommended by clinical guidelines. 1

Types of Urinary Incontinence in Runners

Marathon runners commonly experience different types of urinary incontinence:

• Stress urinary incontinence (SUI): Involuntary leakage during physical exertion, particularly with high-impact activities like running
• Urgency urinary incontinence: Sudden, compelling urge to void that is difficult to defer
• Mixed incontinence: Combination of both stress and urgency symptoms

Evidence-Based Treatment Options

First-Line Treatments

1. Pelvic Floor Muscle Training (PFMT)

   • Strongly recommended for stress urinary incontinence (Grade: strong recommendation, high-quality evidence) 1
   • Studies show up to 70% improvement in symptoms when properly performed 2
   • Number needed to benefit (NNTB) of 3 for improving continence 3
   • Should be supervised by specialist physiotherapists or continence nurses for best results 2
   • Minimum recommended duration: 3 months 2

2. Bladder Training

   • Strongly recommended for urgency urinary incontinence (Grade: strong recommendation, moderate-quality evidence) 1
   • Involves behavioral therapy to extend time between voiding 1

3. Combined Approach for Mixed Incontinence

   • PFMT with bladder training is recommended for mixed UI (Grade: strong recommendation, moderate-quality evidence) 1
   • A combined pelvic floor rehabilitation program including biofeedback, functional electrical stimulation, PFMT, and vaginal cones has shown effectiveness in female athletes 4

4. Weight Loss and Exercise

   • Strongly recommended for obese women with UI (Grade: strong recommendation, moderate-quality evidence) 1, 3

Specialized Training for Runners

For marathon runners specifically:

• Sport-Specific PFMT: Training should include running-specific elements that address the high-impact nature of the activity 5
• Timing of Muscle Activation: Research shows that proper pelvic floor muscle activation before and during foot strike is important for maintaining continence while running 5
• Supervised Programs: Athletes perform better with supervised rehabilitation programs compared to self-directed exercises 4

Treatment Algorithm for Marathon Runners with UI

1. Initial Assessment:

   • Determine type of incontinence (stress, urgency, or mixed)
   • Assess severity and impact on running performance
   • Rule out urinary tract infections or other medical conditions 1

2. First-Line Treatment:

   • For stress UI: Supervised PFMT with running-specific components
   • For urgency UI: Bladder training
   • For mixed UI: Combined PFMT and bladder training

3. Advanced Interventions (if first-line treatment fails):

   • For urgency UI: Consider pharmacologic treatment based on tolerability, adverse effect profile, and cost 1
   • For stress UI: Avoid systemic pharmacologic therapy (strong recommendation) 1
   • Consider referral for specialized sports medicine or urogynecology evaluation

Important Considerations and Pitfalls

• Avoid Common Pitfalls:

  • Underreporting: Many women do not report UI to their physicians; clinicians should proactively ask about symptoms 1
  • Inadequate Training: Unsupervised or leaflet-based PFMT is less effective than supervised programs 2
  • Premature Pharmacologic Treatment: For stress UI, pharmacologic therapy is not recommended as first-line treatment 1

• Running-Specific Factors:

  • High-impact nature of running increases intra-abdominal pressure
  • Proper timing of pelvic floor muscle activation before foot strike is crucial 5
  • Consider temporary modification of training intensity while undergoing treatment

• Monitoring Progress:

  • Success is defined as at least 50% reduction in UI episodes 1
  • Regular follow-up to assess technique and progress is essential

By following this evidence-based approach, many marathon runners can effectively manage urinary incontinence and continue their athletic pursuits with improved quality of life and performance.
