This may increasingly come as information to even veteran runners, however nerves want to maneuver! And tight nerves can have substantial penalties. Not solely can nerves trigger ache, however they will additionally create persistent muscle, joint, and connective tissue stiffness, soreness, and stress — and nerve stress could make us really feel extremely stiff.
Optimum nerve mobility goes far past reducing nerve ache. It could even be the important thing to peak efficiency. This text serves as a primer on nerve stress and gives runners two new, on-the-go nerve stretches to optimize their working mobility.
Nerve Rigidity Outlined
Nerve stress is a deficit of nervous system mobility within the physique. The peripheral nerves are a collection of interconnected “electrical cables” — coated in skinny fascia — that interweave inside, alongside, and between each layer of tissue in our physique: pores and skin, muscular tissues, bones, and organs. But these nerves want to slip and glide amidst all that different tissue.
Why Nerves Get Tight
Nerve stress is widespread for everybody. Numerous life elements — together with impaired posture, trauma (falls and accidents), and even poor hydration — could make a nerve sticky.
Amongst runners, it’s virtually unavoidable. The influence load of working can compress and stiffen the backbone, via which — and out of — the peripheral nerves circulation to our legs and arms. Then, the innumerate muscle contractions, significantly in our legs over many miles and minutes, may cause myofascial stress that compresses the nerves inside and round them.
Lastly, extended dehydration from endurance train may cause neuron-fascial tissues to get sticky and lose their pure glide.

Nerve Rigidity Can Make You Damage
The implications of nerve stress are a number of. Tight nerves may cause ache: signs is usually a uninteresting, or sharp-shooting ache, or each. They trigger different signs, together with burning and tingling. Although extra uncommon, extreme nerve stress may cause numbness and even muscle weak point. An indicator of neurogenic ache is ache at relaxation.
However extra troublesome, is how nerve stress can masquerade as orthopedic ache in two methods. Firstly, nerve stress can amplify a myofascial ache. For instance, a good, irritable medial plantar nerve could make a gentle, 3-out-of-10 plantar fascial pressure into 7-out-of-10 ache.
Secondly, even trickier, nerve stress can create and perpetuate myofascial ache. A good nerve within the decrease leg can create and maintain stiffness, stress, and even set off factors in a calf — a difficulty that no quantity of generalized calf therapeutic massage, stretching, and strengthening will sustainably alleviate.
Furthermore, a good, irritable nerve can create swelling in close by tissues. For instance, that very same tight decrease leg nerve can dump swelling into the heel and ankle, making it seem that you’ve got critically strained the ankle or Achilles. The joint or tendon will swell, get tight, and sore. However makes an attempt to deal with the instant space will lead to short-term enhancements.
The take-home: in such instances, solely by enhancing nerve mobility will the native tissues transfer and performance effectively.

Nerve Rigidity Can Make You Sluggish: The Moist Denims Impact
Lastly, gentle nerve stress could make you gradual. Nerves are extremely delicate constructions. When the nervous system perceives extra stress, it’s going to improve tissue tone — international tightness within the space — to guard the nerve, and stop you from shifting that limb too quick or far.
Certainly, legs with nerve stress really feel objectively heavier and take extra effort to maneuver.
I liken functioning with nerve stress to working in moist denims. If working with a cellular, environment friendly, and relaxed nervous system appears like working in gentle cut up shorts, then working with average to extreme nerve stress can really feel like working in a pair of denim pants, soaking moist. You may transfer, however full vary is proscribed, and it takes far more power to flex and prolong the legs.
But once more, particular myofascial mobility methods usually fail to enhance this pervasive and sometimes extreme stiffness.

Nerve Rigidity Self-Test
Figuring out nerve stress could be difficult. Some runners could be very stiff, but have comparatively cellular nerves. Whereas others could be very flexible — with naturally versatile joints and delicate tissues, but nonetheless have tight, irritable nerves. Assume you may need nerve stress? Strive the next two stretches. If, on the finish of the mobility sequences you are feeling a robust stress sensation, you:
- could have vital nerve stress
- could profit from including common nerve stretching to a efficiency mobility routine.
Within the the rest of this text, we’ll confer with testing and mobilizing the sciatic nerve, which is the biggest nerve within the leg that originates from the decrease backbone and sacrum, runs via the pelvis, and alongside the again of the leg. The sciatic is a big nerve that tends to get tight and irritable in lots of runners. It innervates all of the muscle and pores and skin on the posterior higher thigh and nearly all of the decrease leg and foot. When tight, it could actually trigger ache and stiffness within the hip, hamstring, calf, ankle, and foot.
Joe’s On-The-Go Sciatic Nerve Stretches: Step-by-Step
Sciatic nerve stress testing and pre-activity mobilization is simple. All it takes is your leg, and a foot remainder of some variety. Comply with the steps beneath:
Step 1: Place a foot on an object in entrance of you. Discover a steady object upon which to relaxation your foot — a chair, staircase, bench, rock, or perhaps a car bumper. The optimum peak is determined by your general flexibility: If stiff, the article could be low: a few stairs, or a low stool. When you’re significantly flexible, you could want a excessive floor like a desk or countertop.
Place your foot on the article, with a straight knee and the foot flexed upward. An optimum object peak will lead to a lightweight stretch sensation behind the leg.

Step 2: Level the pelvis towards the foot. Flip your hips in order that they face your foot. This usually will improve the stretch, at the very least barely.
Step 3: Carry out these two strikes.
- Facet Bend Away from the Stretched Facet – Holding the pelvis stage, aspect bend your backbone away from the stretch leg. It could assist to slip your hand alongside the other leg, reaching towards your stance foot. For instance, if stretching the correct leg, the left hand will slide down, alongside the left leg, reaching towards the left foot.

- Rotate Towards the Stretched Facet – Holding the pelvis stage, rotate the trunk towards the stretch leg. The outer (stance leg) shoulder ought to twist towards the stretch foot. For instance, if stretching the correct leg, twist the left shoulder towards the correct foot.

Step 4: Oscillate the Motions – Optimum nerve mobilization entails small and gradual on-and-off motion. This may be within the type of tensioning — making use of stretch strain — or via flossing (be taught extra about flossing beneath on this article).
Indicators of Sciatic Nerve Rigidity
As soon as on this place, a traditional sensation is only a gentle improve in leg stress when the spinal aspect bend, or rotation, is utilized. Indicators of constructive and related sciatic nerve stress embrace:
- a robust to extreme stretch sensation
- a stretch sensation that replicates ache, different signs, or persistent stress.
If performing the stretch leads to extreme stress, or the replication of ache, aching, capturing ache, tingling — situated wherever within the leg or backbone, together with the foot, decrease leg, hamstring, anterior thigh, pelvis, or low again — then you could have vital nerve stress, and it’s time to get it shifting!
Don’t Yank, Wiggle: Advantages of Three-Dimensional Nerve Mobilization
[Author’s Note: These two stretches are adaptations of the pioneering work of physiotherapist Bob Elvey and protege, Jack Stagge.]
A cursory web search of nerve mobilization will lead to two major varieties of stretches:
1. Flexion-Based mostly Tensioners
These are methods the place the nerve is tensioned — lengthened between the backbone and limb — and involving flexion — the forward-bending of the physique or particular person joints. For instance, a sciatic nerve flexion tensioner stretch entails a foot on an object, adopted by a easy spinal flexion.
2. Flossing
It is a extra nuanced technique the place the nerve is tensioned on one finish of its size, whereas slackened on the opposite. This creates a flossing impact, the place the nerve is pulled barely, both extra proximally (towards the backbone), or distally (away). With sciatic nerve flossing, a foot could also be on an object, however when the backbone flexes ahead (tensioning the proximal nerve), the foot plantarflexes (slackening the distal nerve) on the identical time. Oscillating this motion creates a flossing-like impact.
However sticky nerves could be cussed, usually requiring a couple of or two methods to get free. Joints have a number of various kinds of motion: flexion, but in addition extension, aspect bending, and rotating in a number of instructions. Why not contain all of them?
These two methods make use of each aspect bending and rotation, they usually afford the chance so as to add the opposite motions — significantly flexion and extension — in addition to flossing. The extra novel actions, the extra possible it’s to sustainably free the nerve and restore environment friendly nerve mobility.

Superior Sciatic Nerve Mobility Methods
Upon getting discovered nerve stress and established the foot-on-object place, experiment with numerous actions to intensify the stretch. Choices embrace:
1. Decrease Physique Rigidity Methods
Motion methods for the leg embrace:
- ankle dorsiflexion and plantar flexion
- knee flexion and extension
- hip hinging
2. Higher Physique Rigidity Methods
Motion methods above the leg embrace:
- neck flexion, extension, aspect bending, or rotation
- arm actions similar to straight overhead or lateral raises
3. Flossing Methods
Wanna’ take a look at your coordination? Flip any tensioner technique right into a flossing technique by combining a tensioning and slackening. An instance consists of, chin-to-chest (neck flexion) with ankle plantarflexion. Any higher physique motion paired with a decrease physique motion can be utilized as a flossing technique.
Nerve Stretching: When and How A lot
Whereas they want movement to be wholesome and performance correctly, nerves are extremely delicate constructions. They hate stretching! Extended, aggressive stretching of those electrical cables usually leads to worsening signs.
Optimum nerve mobilization ought to embrace:
- Excessive Frequency: Stretch nerves as usually as 4 or 5 instances a day.
- Low Period: Extended stress could be extremely irritable to nerves. Maintain stress for only some seconds. Higher but, oscillate with gradual on and off stress or flossing movement.
- Average Repetition: As few as 8 to 10, to as many as 20 to 30, oscillating repetitions is lots, and they need to not final greater than 30 to 60 seconds in whole period.
- Timing: The perfect instances to mobilize nerves consists of the morning, pre-physical exercise, after extended inactivity similar to sitting, and within the night, or earlier than sleeping.
Conclusion
Nerve mobility is vitally vital, not only for ache aid however for full and unrestricted movement. Tense nerves are answerable for not solely nerve ache, however quite a lot of persistent myofascial aches and pains, and will stubbornly prohibit any movement within the physique.
Even in case you do not need nerve ache, or don’t really feel significantly stiff, verify in together with your nerve mobility. Enhancing it might make working really feel lighter, simpler, and quicker!
