Belt Usage and Urinary Incontinence in Strength Athletes

By Dr. Christine Martirez PT, DPT on 11/11/2024

For strength athletes like weightlifters, powerlifters, and Strong competitors, pushing the limits of physical strength is a core part of their training. However, many athletes—particularly women—may notice an unexpected side effect during heavy lifts: urinary leakage. This issue is often tied to a combination of factors, including the use of lifting belts, intra-abdominal pressure management, and the function of the pelvic floor muscles. In this post, we’ll explore why stress incontinence can occur in strength athletes, the role of the core in maintaining intra-abdominal pressure, the impact of lifting belts, and how pelvic floor physical therapy can help address this issue to optimize performance and reduce leakage.

The Role of Intra-Abdominal Pressure in Lifting

When lifting heavy weights, athletes rely on intra-abdominal pressure (IAP) to stabilize the spine and protect it from injury. This pressure acts like a natural brace, allowing for safer and more efficient force transfer during lifts such as squats, deadlifts, and presses. However, the creation of IAP is not just about bracing or wearing a lifting belt; it’s about how the entire core functions as a unit.

The Anatomy of the Core: Working Together for Stability

The core is more than just your abs. It’s a system of muscles that work together to maintain intra-abdominal pressure and stabilize the spine. Key muscles involved include:

• Diaphragm

  The dome-shaped muscle under the ribs that assists with breathing and pressure management.

• Transverse Abdominis (TrA)

  The deepest abdominal muscle that acts like a corset to support the spine.

• Pelvic Floor Muscles

  The hammock-like group of muscles that support the pelvic organs and control urinary function.

• Multifidi

  Small muscles that stabilize the vertebrae in the lower back.

During a heavy lift, the diaphragm contracts and pushes down, while the pelvic floor lifts upward. This creates a stable "canister" of pressure that supports the spine. The transverse abdominis and multifidi work to cinch the abdomen and stabilize the spine from all sides.

The Role of Lifting Belts in Managing Intra-Abdominal Pressure

Lifting belts are commonly used by strength athletes to supplement the body’s natural intra-abdominal pressure. By providing an external source of support, belts help brace the core, allowing athletes to lift heavier weights with reduced risk of spinal injury. However, belts do not replace the natural function of the core muscles; instead, they enhance it. When used correctly, a belt can help increase intra-abdominal pressure, but if not managed properly, this additional pressure can spill into areas that are not designed to handle it—namely, the pelvic floor.

How Stress Incontinence Occurs During Heavy Lifts

Stress incontinence refers to the involuntary leakage of urine during activities that increase intra-abdominal pressure, such as lifting, running, or jumping. For athletes, stress incontinence often happens at the bottom of a heavy squat or deadlift, when pressure in the abdominal cavity peaks. Why does this happen?

• Pelvic Floor Overload

  When intra-abdominal pressure becomes too high, the pelvic floor muscles may not be able to counteract that force effectively, leading to leakage.

• Improper Core Engagement

  If an athlete uses a lifting belt but fails to properly engage their core muscles (especially the pelvic floor), the extra pressure from the belt can worsen leakage.

• Weak or Overactive Pelvic Floor

  Athletes with either weak or overly tight pelvic floor muscles may experience leakage when lifting heavy due to poor pressure management.

How Pelvic Floor Therapy Can Help Strength Athletes

Pelvic floor physical therapy can play a significant role in helping strength athletes manage and reduce stress incontinence. Here’s how:

1. Assessing Pelvic Floor Function

A pelvic floor therapist will evaluate the strength, coordination, and endurance of your pelvic floor muscles. They can identify whether the muscles are weak, overactive, or not engaging properly during heavy lifts.

2. Educating on Proper Core Engagement

Many athletes are unaware of how to effectively coordinate their core muscles to create intra-abdominal pressure without overloading the pelvic floor. Pelvic floor therapy focuses on teaching athletes how to engage their diaphragm, transverse abdominis, and pelvic floor together to maintain optimal pressure.

• Breathwork Techniques

  Learning how to use your breath to create IAP without straining the pelvic floor is key. This might involve diaphragmatic breathing techniques to help relax and control the pelvic floor.

• Bracing Without Bearing Down

  Athletes are taught how to brace their core without excessively bearing down, which can force pressure into the pelvic floor and lead to leakage.

3. Optimizing Lifting Belt Use

Pelvic floor therapists can guide athletes on how to use lifting belts effectively. This includes:

• Understanding when to use a belt (e.g., only during maximal lifts rather than every lift).

• Learning how to create abdominal pressure against the belt without overloading the pelvic floor.

• Practicing progressive overload techniques to ensure the pelvic floor can handle the increased pressure over time.

4. Strengthening and Balancing the Pelvic Floor

Therapists will guide athletes through exercises to either strengthen weak pelvic floor muscles or relax overly tight ones. This can include:

• Pelvic floor muscle training (Kegels)

  For those with weak muscles.

• Pelvic floor relaxation techniques

  For those with overly tight muscles.

• Hip and core strengthening

  Focusing on surrounding muscles to better support the pelvic floor.

5. Progressive Return to Heavy Lifting

After addressing any pelvic floor dysfunction, therapists can guide athletes through a safe progression back to heavy lifting. This includes:

• Gradual reintroduction to maximal lifts with a focus on proper form.

• Modifying training programs to include pelvic floor-safe exercises.

• Monitoring symptoms to ensure that leakage does not return.

Experiencing urinary leakage during heavy lifting can be frustrating, but it doesn’t mean you need to give up your sport. Understanding how your core and pelvic floor work together to manage intra-abdominal pressure is crucial. By working with a pelvic floor physical therapist, you can learn strategies to manage pressure effectively, improve pelvic floor strength and coordination, and lift confidently without leakage.If you’re experiencing stress incontinence during lifting, consider reaching out to a pelvic floor physical therapist to help you optimize your performance and protect your pelvic health. With the right guidance, you can continue to excel in your sport while maintaining control over your body.
