🦿FIELD NOTES | MODULE 3: BIOMECHANICS OF SHIBARI
LESSON 14: TIME UNDER LOAD: FATIGUE & VISCOELASTICITY

Just because a body isn’t moving doesn’t mean its mechanics aren’t changing.

In Shibari, sustained loading affects both human tissues and rope materials through viscoelasticity, or time-dependent mechanical behavior.

Two key concepts:

Creep: Under constant stress, a material gradually deforms. Think of a cushion slowly compressing under your weight.

Stress relaxation: Under constant strain, internal stress decreases over time. Same stretch, less force.

Skin, tendons, ligaments, and even jute rope exhibit time-dependent behavior, influenced by material properties, moisture, and loading conditions.

Meanwhile, neuromuscular fatigue can change how the body maintains a position.

A tie that initially feels manageable may change over time.

Ask: Has pressure, sensation, muscular effort, or support changed?

Stillness doesn’t mean nothing is changing.

⚠️ SAFETY: Sustained loading can affect nerves, circulation, and soft tissues. Monitor sensation, comfort, movement, and support. Reduced tension doesn’t necessarily mean reduced risk. Educational content only.

LESSON 13: DYNAMIC LOADING, ACCELERATION & MOMENTUM

What happens when a body in Shibari starts moving?

Movement changes the forces involved.

A stationary load and a moving load don’t necessarily place the same demands on a rope system.

Three important concepts help explain why:

Acceleration: A change in velocity, including speeding up, slowing down, or changing direction.

Momentum: The quantity of motion an object has, determined by its mass and velocity.

Impulse: The change in momentum produced by force acting over time.

Here’s the important part: stopping a moving body requires changing its momentum.

For the same change in momentum, increasing the stopping time generally reduces the average net force required.

In Shibari suspension and transitions, this matters when lifting, lowering, rotating, swinging, or bringing a body to a stop.

The forces involved depend on acceleration, direction, positioning, and how the load is supported.

A system that supports a stationary body isn’t necessarily experiencing the same forces during movement.

Ask:
• How is the body moving?
• How quickly is its velocity changing?
• What happens when that movement stops?

⚠️ SAFETY: Educational content only, not a substitute for hands-on suspension training. Dynamic movements can introduce additional or changing loads. Use appropriately rated equipment, suitable anchors, controlled transitions, and qualified instruction. Avoid uncontrolled drops or sudden stops.

LESSON 12: ASYMMETRY & INDIVIDUAL VARIATION

Just because a rope position looks symmetrical doesn’t mean both sides of the body are experiencing it the same way.

Human bodies aren’t perfectly symmetrical, and that’s normal.

Your left and right sides can differ in mobility, strength, coordination, anatomy, and injury history.

In Shibari, even when rope placement and body positioning appear identical, the mechanical demands may be different.

One shoulder might have less active range of motion. One side might require more muscular effort, fatigue sooner, or experience a different sensation.

And you can’t determine all of that just by looking.

Visual symmetry ≠ mechanical symmetry.

Rather than assuming both sides have the same capacity, compare each side to that person’s individual baseline.

Ask:
• Does this side move differently?
• Does this side feel different?
• What changes with position, load, or time?

The goal isn’t perfect symmetry. It’s understanding the individual body you’re tying.

⚠️ SAFETY: Educational content only, not a substitute for hands-on Shibari instruction or medical assessment. Assess each side individually, communicate throughout, and never force a position to achieve visual symmetry.

LESSON 11: MOVEMENT CHAINS & COMPENSATION

When you reach overhead, your arm isn’t working alone.

Your upper arm, shoulder blade, and sometimes your torso coordinate to produce what looks like one simple movement.

This is part of how movement chains work.

But what happens when one movement becomes restricted?

Your body may change its strategy, using movement elsewhere to accomplish the same task. This is called compensation, and it isn’t automatically harmful.

In Shibari, rope can restrict movement at one joint while changing how other parts of the body contribute.

So don’t just watch the area you’ve tied. Ask:

What moved before? What did the rope restrict? Where is the movement happening now?

A change in one movement option can change how the rest of the body moves.

⚠️ SAFETY: Educational content only, not medical advice or a substitute for hands-on Shibari instruction. Compensation isn’t inherently unsafe, but altered movement may change loading and physical demands. Consider individual mobility, strength, injury history, fatigue, positioning, and support. Communicate, monitor sensation and function, and adjust as needed.

Which nodome is open: A or B? You have 5 seconds.

In shibari, pull direction matters: a closed nodome tightens under the outgoing rope’s pull; an open one tends to loosen, weakening its grip.

LESSON 10: COMPRESSION, TENSION & SHEAR

How is rope actually loading the body?

Force can act on tissue in different ways.

Compression pushes tissue together.
Tension pulls tissue apart.
Shear involves forces acting parallel to a surface or material, tending to make adjacent parts shift relative to one another.

And these can occur at the same time.

At the rope-skin interface, friction also matters because it resists sliding and affects how force is transferred between surfaces.

This gives us a better question than simply:

“How tight is the rope?”

Ask:

Is this tissue being compressed, stretched, or sheared? Is the rope staying in place or sliding across the skin?

Because the amount of force is only part of the story. How that force acts on the body matters too.

⚠️ SAFETY: This is a simplified biomechanics model for education, not medical advice or a substitute for hands-on Shibari instruction. Real tissue loading is complex and can involve multiple forces simultaneously. Individual anatomy, tissue characteristics, rope placement, movement, load and time all matter. Monitor sensation, movement and function, communicate continuously, and modify or stop when needed.

LESSON 9: STABILITY & BASE OF SUPPORT

Why is it easier to lose your balance when your feet are together?

Your weight didn’t change. Your base of support did.

In biomechanics, stability depends partly on the relationship between the body’s center of mass and its available supports. Change those supports, and you change the mechanical problem the body has to solve.

That becomes especially interesting in Shibari.

Rope can change where support comes from. Feet can leave the floor. Bodies can rotate. During transitions, the relationship between the body and its supports can continuously change.

And stability isn’t always the goal.

Sometimes we intentionally create controlled instability.

So instead of only asking, “Is this stable?” ask:

What is supporting this body right now, and what happens when that support changes?

Stability isn’t fixed. It’s something the whole system creates.

⚠️ SAFETY: Educational content only, not medical advice or a substitute for hands-on Shibari instruction. Stability in a living, moving or rope-supported body is more complex than a standing model. Individual anatomy, movement capacity, fatigue, rope placement, loading, transitions and the entire support system matter. Communicate continuously, introduce changes progressively, and maintain an appropriate emergency plan.
