171 How the Feet, Ankles, Hips, Pelvis, and Core Work Together in Teenage Runners

Running may look like a simple activity, but every stride requires coordination throughout the body.

The foot makes contact with the ground. The ankle responds to the surface. The knee moves forward. The hip controls the leg. The pelvis transfers force between the lower and upper body. The core helps organize the trunk, while the arms and shoulders counterbalance the motion.

When these areas coordinate well, running may feel smooth and efficient. When one area is sore, restricted, fatigued, or recovering from an injury, another area may take on more work.

This whole-body relationship is especially important for teenage cross-country and track athletes. Their bodies are still developing while they manage repetitive training, competition, school, and recovery.

At Orthopedic Massage Therapy in Grapevine, Texas, I do not look only at the location where a young runner feels sore. I observe how the feet, ankles, hips, pelvis, core, spine, and upper body work together.

Every Running Stride Begins at the Ground

The foot is the first part of the body to meet the ground during running.

As the foot contacts the surface, the body must absorb force, stabilize, and prepare to move forward. The ankle changes position while the lower leg, knee, and hip respond above it.

Different runners naturally use different foot-strike patterns. Some contact the ground closer to the heel, some closer to the midfoot, and others closer to the forefoot.

No single foot-strike pattern automatically explains every injury.

Research comparing running biomechanics and injury risk remains limited and sometimes inconsistent. One large systematic review found minimal evidence that most isolated biomechanical differences consistently predict running injuries.

That is why one feature—such as foot position—should not be evaluated without considering the rest of the runner.

The Ankle Helps Absorb and Transfer Force

The ankle must be mobile enough to adapt to the ground and stable enough to help the runner move forward.

Cross-country runners encounter hills, grass, dirt, uneven terrain, and changing surfaces. Track athletes repeatedly run around curves and may perform high-speed drills, starts, jumps, or interval training.

If one ankle is sore or restricted, the athlete may begin changing the stride.

A parent or therapist may notice:

• Reduced ankle movement

• One foot turning outward

• Shorter steps on one side

• Less time spent on one leg

• Difficulty pushing away from the ground

• Uneven calf tension

• Visible swelling around one ankle

• A change in balance

These observations do not identify a diagnosis. They indicate that the athlete’s movement deserves closer attention.

An Old Ankle Injury Can Influence More Than the Ankle

A sprained ankle may begin feeling better before full confidence and comfortable movement return.

The young runner may continue protecting that side without realizing it. The body may shift more force toward the opposite leg or change how the knee and hip move.

Over time, the athlete may report discomfort in another area:

• The opposite ankle

• A knee

• A hip

• The pelvis

• The lower back

This does not prove that the old ankle injury caused the new pain. It means that previous injuries and compensation patterns should be included in the assessment.

Research on running-related injuries has repeatedly identified previous injury as an important risk factor to consider.

That is one reason I ask young athletes and parents about injuries that happened months or years earlier.

The Knee Responds to the Foot and Hip

The knee is located between the ankle and hip. Its movement is influenced by what happens both above and below it.

When the foot meets the ground, the ankle, knee, and hip work together to manage force. If the ankle is not moving comfortably, the knee may respond differently. If the hip is fatigued or restricted, the position of the thigh may affect how the knee tracks during the stride.

Young runners frequently report knee soreness, but treating only the knee may miss other important areas.

I may observe:

• Foot and ankle movement

• Hip rotation

• Pelvic position

• Balance on one leg

• The relationship between the knee and foot

• How the athlete walks

• Whether the athlete shifts weight away from one side

I am not diagnosing a knee condition. I am observing how the body organizes movement.

Persistent, swollen, or activity-limiting knee pain should be evaluated by a pediatrician, sports-medicine doctor, physical therapist, or athletic trainer.

The Hips Help Control the Legs

The hip must move through every running stride while helping control the position of the thigh.

Running requires coordination between the muscles at the front, back, inside, and outside of the hip. The gluteal muscles, hip flexors, adductors, hamstrings, and surrounding connective tissues all contribute.

A teenage runner may describe:

• Tight hip flexors

• Sore gluteal muscles

• Hamstring tension

• Pulling at the front of the hip

• Uneven stride length

• Difficulty extending one leg behind the body

• Lower-back tightness after running

• One hip feeling stronger or looser than the other

These sensations may change as the athlete grows, increases mileage, adds speed work, or begins strength training.

Research concerning adolescent running mechanics is still limited, and findings from adults should not automatically be applied to growing athletes.

The young runner should be treated as an individual rather than as a smaller version of an adult athlete.

The Pelvis Connects the Legs to the Spine

The pelvis is an important transfer point between the lower and upper body.

Each hip connects to the pelvis, while the lumbar spine rests above it. During running, the pelvis moves and rotates as the legs alternate. This motion must coordinate with the trunk and arms.

If one hip does not move as comfortably, the pelvis may rotate, tilt, or shift differently. The lower back or upper body may then contribute more movement.

This may be seen as:

• Uneven hip motion

• One side of the pelvis moving forward differently

• Increased lower-back movement

• Changes in trunk rotation

• Uneven arm swing

• Difficulty balancing on one leg

• One stride looking shorter

These observations can help guide treatment, but they should not be used to claim that every pain is caused by a “misaligned pelvis.”

The body is adaptable, and natural movement varies between individuals.

The Core Is More Than the Abdominal Muscles

Many people think of the core as the visible abdominal muscles. The functional core includes a larger group of structures that help manage pressure, breathing, stability, and movement.

This may include:

• Abdominal muscles

• Diaphragm

• Pelvic floor

• Muscles around the lumbar spine

• Iliacus

• Psoas

• Quadratus lumborum

• Deep stabilizing muscles

• Fascia connecting the trunk and pelvis

During running, the core helps organize the relationship between the pelvis, spine, rib cage, and limbs.

The core does not need to remain rigid. It must respond and adapt while the athlete breathes and moves.

A runner with poor coordination through the trunk may use more tension than necessary. The shoulders may rise, the lower back may become guarded, or breathing may feel restricted.

Orthopedic massage therapy may include comfortable work around the abdomen, pelvis, hips, lumbar area, lower thoracic area, and diaphragm when appropriate and with clear communication and consent.

Breathing Is Part of Running Mechanics

Running increases the body’s demand for oxygen. The diaphragm and rib cage must move repeatedly as pace and effort change.

Breathing is not separate from core function.

The diaphragm contributes to respiration and interacts with the abdominal wall, spine, rib cage, and pelvic floor. When the athlete becomes fatigued, breathing patterns and upper-body tension may change.

A parent may notice that the runner:

• Raises the shoulders while breathing

• Becomes stiff through the upper body

• Has limited arm swing

• Rotates less through the thoracic spine

• Complains of neck or upper-back tightness

• Feels restricted around the lower ribs

These observations do not automatically indicate a diaphragm problem. They suggest that breathing and trunk movement should be considered as part of the full picture.

The Arms and Shoulders Help Balance the Stride

Although running is often considered a lower-body activity, the arms and shoulders also contribute.

As one leg moves forward, the opposite arm typically moves forward. This helps counterbalance rotation through the pelvis and trunk.

If the thoracic spine or shoulder is restricted, arm swing may change. If the pelvis is moving differently, the upper body may compensate.

A teenage runner may seek help for neck or shoulder tension even though the main training demand comes from the legs.

This is why I may assess the pelvis, core, thoracic spine, and breathing when someone reports upper-body discomfort associated with running.

The place that hurts is important, but it may not be the only area involved.

Fatigue Can Change How the Body Manages Force

A runner’s movement near the beginning of practice may look different from movement near the end.

As muscles become tired, the body may redistribute force between the ankles, knees, hips, and trunk. A recent systematic review found that running-related fatigue can produce lower-limb biomechanical changes and shifts in mechanical demand, although the exact relationship to injury remains complex.

This does not mean every movement change caused by fatigue will produce an injury.

It means that pain occurring only after a certain distance or late in practice is useful information.

I may ask:

• When does the discomfort begin?

• Does it appear during speed work or long runs?

• Is it worse on hills?

• Does it change with the running surface?

• Does the athlete limp afterward?

• How long does recovery take?

• Is the athlete sleeping and eating adequately?

• Has training recently increased?

The answers help create a more complete view.

How Orthopedic Massage May Support the Running Chain

Pain-free orthopedic massage therapy may support a teenage runner by addressing muscular and fascial restrictions while observing how different body regions work together.

A session may include:

• Movement assessment

• Comparison between sides

• Comfortable myofascial work

• Pain-free massage

• Supported hip or ankle movement

• Work around the pelvis and core

• Attention to the diaphragm and breathing

• Reassessment after treatment

• Communication with the athlete and parent

The goal is not to force the body into perfect symmetry.

Small differences between sides are normal. The goal is to determine whether a restriction appears relevant to the athlete’s comfort, movement, recovery, or performance.

Reassessment Shows Whether the Approach Is Helpful

After treating a particular area, I may ask the athlete to repeat a movement.

The young runner might:

• Move the ankle

• Bend the knee

• Rotate the hip

• Balance on one leg

• Turn the torso

• Raise an arm

• Stand or walk

We then compare the response.

Does the movement feel easier? Does the athlete feel more balanced? Has the pulling sensation changed? Is the body less guarded?

This information helps determine what should happen next.

If treatment does not create a useful change, the plan may need to change. If the symptoms suggest an injury, medical or rehabilitation evaluation may be more appropriate.

My Policy for Teenage Athletes

Every client under 18 must have a signed parent or guardian release and must be accompanied by a parent or guardian throughout the appointment.

The young athlete’s own comfort and permission are also required.

Clients wear athletic shorts and a tank top so they remain comfortable and covered. Treatment and hand placement are explained, pressure remains pain-free, and the athlete can request a change or stop at any time.

I use a body-support system on my Stronglite Premier portable massage table so the head, chest, pelvis, and legs can be positioned comfortably.

These policies create a professional environment for the athlete, parent, and therapist.

Knowing When to Refer

I am a licensed massage therapist, not a doctor. I do not diagnose running injuries or clear athletes to return to competition.

A young runner needs appropriate medical evaluation when there is:

• Severe or worsening pain

• Significant swelling

• Inability to bear weight

• A visible deformity

• New numbness or weakness

• Pain after a significant fall

• Persistent pain at rest

• Possible stress injury

• Recurring pain that limits running

• Symptoms that do not improve with appropriate rest

Massage therapy should not delay care from a pediatrician, sports-medicine physician, orthopedic doctor, physical therapist, or athletic trainer.

Supporting the Whole Teenage Runner in Grapevine, Texas

The feet, ankles, knees, hips, pelvis, core, spine, shoulders, and breathing system all participate in running.

That does not mean every running injury has one hidden cause somewhere else in the body. It means the athlete should be evaluated as a whole person rather than as a single painful body part.

At Orthopedic Massage Therapy, I provide pain-free, individualized treatment while listening to the young athlete and parent, respecting my massage-therapy license, and collaborating with other professionals when necessary.

The goal is to support continued improvement in movement, balance, stability, strength, power, flexibility, recovery, and confidence.
