Sarcopenia (Muscle Loss)
What is Sarcopenia?
Sarcopenia is age-related muscle loss that affects skeletal muscle throughout the body. It involves a gradual decline in muscle strength, muscle mass, and physical function over time. While it is most commonly associated with aging, changes in muscle strength and muscle mass can begin earlier than many people expect.
This process affects more than the muscles in the arms and legs. The pelvic floor is also made of skeletal muscle, and age-related muscle changes may contribute to reduced pelvic support and changes in bladder or bowel control in some individuals. Declining muscle strength throughout the body can also affect posture, balance, and overall stability.
As muscle fibers shrink and muscle size decreases, everyday movements may begin to feel more difficult, less stable, or less controlled.
- Loss of muscle strength when lifting objects or climbing stairs
- Reduced endurance during physical activity
- Balance changes or increased risk of falls
- Slower walking speed or decreased physical performance
- Changes in body composition, including reduced lean muscle mass and increased fat mass
- Slower recovery after illness, injury, or periods of inactivity
- In some individuals, reduced pelvic support or bladder leakage
At Beyond Basics, our pelvic floor physical therapists address age-related muscle changes through targeted, progressive care. Treatment focuses on rebuilding strength, improving coordination, and restoring functional movement patterns so patients can maintain independence, stability, and confidence in daily life.
What Causes Sarcopenia?
Sarcopenia develops from a combination of age-related muscle changes, hormonal shifts, reduced physical activity, and metabolic factors. As the body ages, skeletal muscle becomes less responsive to the signals that stimulate muscle growth and repair. Researchers refer to this process as anabolic resistance, meaning the body requires greater stimulation through resistance exercise and adequate nutrition to maintain muscle mass.
Muscle loss can accelerate during periods of illness, injury, prolonged inactivity, or recovery from surgery. These changes often develop gradually, which means declining muscle strength may not be noticeable until everyday activities begin to feel more physically demanding. Without intervention, sarcopenia can continue to progress, affecting strength, mobility, balance, and overall physical function.
Contributing factors can include:
- Reduced participation in resistance or strength training
- Lower overall physical activity levels
- Postmenopausal hormonal shifts that affect muscle metabolism
- Chronic inflammation or metabolic conditions
- Inadequate protein intake or nutritional imbalances
Without intervention, muscle loss progresses and impacts both whole body strength and pelvic floor support.

What Does the Pelvic Floor Have To Do with Muscle Loss?
The pelvic floor is part of the body’s deep core system, working together with the diaphragm, abdominal muscles, and hips to support posture, movement, and pressure regulation within the abdomen.
Like other skeletal muscles, the pelvic floor can be affected by age-related muscle changes and declines in muscle strength. When overall muscle strength and coordination decrease, the pelvic floor may become less effective at supporting the bladder, bowel, and pelvic organs.
Changes in pelvic floor muscle function may contribute to symptoms such as:
- Urinary leakage with coughing, sneezing, or lifting
- Pelvic pressure or a feeling of pelvic organ descent
- Changes in sexual function or discomfort during intimacy
- Difficulty maintaining balance or core stability
- Changes in bowel control
Effective treatment for sarcopenia often needs to consider the entire muscular system, including the pelvic floor. Improving muscle coordination, strength, and endurance in this region can support bladder control, pelvic stability, and overall physical function.
Why Muscle Loss Can Affect Pelvic Floor Function
Pelvic floor dysfunction related to muscle loss often develops gradually. As overall skeletal muscle strength declines, the pelvic floor may lose strength, endurance, and coordination, particularly when combined with reduced physical activity.
- Age-related muscle loss affecting overall skeletal muscle strength
- Reduced participation in resistance or strength training
- Hormonal shifts that influence muscle and connective tissue
- Periods of illness, surgery, or prolonged inactivity
- Reduced core and hip stability that increases strain on the pelvic floor
- Changes in body composition that alter pressure and load through the pelvis
Benefits of Working with a Pelvic Floor Physical Therapist for Sarcopenia
Sarcopenia is not simply about muscle loss. It also affects strength, coordination, balance, and overall movement quality. Addressing these changes requires more than general exercise. Pelvic floor physical therapists are trained to evaluate how muscles throughout the body work together, including the hips, core, and pelvic floor.
At Beyond Basics Physical Therapy, we focus on measurable progress while respecting your starting point. Treatment plans are individualized and designed to help you rebuild strength, restore movement, and maintain independence as your body changes.
Working with a pelvic floor physical therapist can help you:
Improve muscle strength safely and progressively
Support healthy muscle development through guided resistance training
Restore coordination between the hips, core, and pelvic floor
Help slow or prevent further muscle loss
Improve balance and reduce fall risk
Support bladder, bowel, and pelvic organ function
Build endurance and confidence in daily movement
Address muscle changes before they begin to limit independence
What To Expect
At your first visit, your therapist will assess your movement patterns, posture, breathing mechanics, and overall strength. We look at how sarcopenia is affecting your daily life and where muscle loss shows up functionally.
Your evaluation may include strength testing, balance assessment, and pelvic floor muscle testing if appropriate. We will discuss your goals, activity level, and any history of injury or inactivity that contributed to changes in muscle mass.
You will leave with a clear plan that includes structured exercises designed to increase muscle mass and rebuild strength gradually.
Sessions last about an hour and focus on progressive resistance training, functional strength work, and neuromuscular retraining.
Your therapist adjusts intensity based on your response. As muscle strength improves, we advance loading to continue building skeletal muscle capacity and preventing further muscle loss. Progress happens steadily. The goal is long-term durability, not short bursts of effort.
