Defence Against Muscle Cramps

Why Do Muscle Cramps Occur?

Electrolyte Imbalance^2,3

Muscle contraction is controlled by electrolytes (calcium, sodium, potassium, chloride, and magnesium). These ions are essential for proper nerve signal transmission and muscle innervation. For example: when a nerve sends a signal, calcium flows into the muscle cell; when calcium is transported back into storage, the muscle relaxes. During a cramp, this process is disrupted:

• either too much calcium remains inside the cell,
• or the nerve keeps firing continuously,
• or the muscle fiber does not receive enough energy to relax.

This is why it feels like the muscle “won’t let go.”

When magnesium enters the cell, it displaces calcium ions. Therefore, if magnesium levels are low, calcium becomes “trapped” in the system and the muscle cannot fully relax, leading to cramps or persistent tightness.

What can you do about it? Proper electrolyte replenishment and adequate hydration are essential. During long endurance workouts (running, swimming, cycling, certain CrossFit elements), it is recommended to replenish electrolytes every 45–60 minutes.

Disruption of Nervous System Control⁴

One of the most important biomechanical causes of cramps is excessive activity of the motor nerve. This may occur as a protective reflex (e.g. due to overload or sudden stretching), nerve irritation (e.g. spinal issues), or the previously mentioned electrolyte imbalance.

In such cases, the motor nerve continuously sends impulses, preventing the muscle from exiting the contracted state.

What can you do about it? Regular therapeutic and sports massage, trigger point therapy, and manual therapy techniques can help release overly tense muscles.^5,6

Energy Deficit⁶

Muscles do not relax passively; relaxation itself also requires ATP. If the muscle is overloaded, poorly circulated, or cold, it has less energy available for relaxation. In such cases, the muscle can become mechanically “stuck.”⁶

This is why muscle cramps are so common at night, after prolonged sitting, or at the end of intense training sessions.

What can you do about it? Exercise is important, but choosing the right training volume and strictly following recovery protocols is just as essential. In strength sports, creatine is particularly effective as an “energy-enhancing and recovery-supporting ingredient.” Today, creatine is widely recognized as a natural “performance booster,” which you can read more about in. For creatine supplementation, OstroVit Creatine Monohydrate powder is one of the best value-for-money options.

The Biomechanical Role of Fascia and Connective Tissue

Cramps are not solely a muscular phenomenon. Tightness or adhesions in the fascia can irritate peripheral nerves, reduce muscle gliding ability, and create muscle knots (trigger points).⁷

Trigger points are especially interesting because they maintain a constant low-level “cramp” that can at any time escalate into a large, painful spasm.

What can you do about it? In addition to deep tissue and trigger point therapy, releasing fascial tension with appropriate soft tissue techniques is also important.

The Kinetic Chain – When the Problem Originates Elsewhere

If one joint or muscle chain does not function optimally, neighboring areas become overloaded. For example:

• limited ankle mobility can overload the calves, resulting in nighttime cramps,
• hip instability can cause overcompensation in the posterior thigh chain, leading to cramps during running,
• weak glutes can result in overactivation of the calves and hamstrings.

In such cases, the cramp is a compensatory reflex, not a localized problem.

What can you do about it? It is worth consulting a rehabilitation specialist, movement therapist, or physiotherapist. After proper assessment and testing, a good professional can reveal an incredible amount of information about your body.

When the Body “Panics”

There are two important sensory receptors in the muscles: the muscle spindle, which detects stretching and initiates contraction if it perceives movement as “too fast,” and the Golgi tendon organ, which detects tension and initiates relaxation if it senses excessive strain.⁸

These two “receptors” work in opposition. During cramps, their balance is disrupted.

In one case, if the muscle is too tight or too short, the muscle spindle becomes hypersensitive and may trigger contraction even at rest.

In another case, if the Golgi tendon organ does not function properly (e.g. due to fatigue or micro-injuries), it cannot stop the tension.

Both situations create a positive feedback loop: the more the muscle cramps, the more signals it receives telling it to continue cramping.

What can you do about it? Early recognition is important. In the initial phase of cramps, direct stretching may help. Do not wait until cramps become regular — start addressing them with electrolyte replenishment, manual therapy, physiotherapy, and creams.

Stretching, Mobilization, and Strengthening – How They Work Together

Stretching alone does not always solve cramps. The goal is achieving “balance,” which requires several types of movement.

Effective approaches:

• Dynamic mobilization to increase range of motion – by incorporating mobility training.
• Strengthening for controlled muscle lengthening – through Pilates and core training.
• Stabilization exercises to reduce overload – with the help of a rehabilitation trainer or physiotherapist.
• Nerve glide techniques to relieve peripheral nerves – with guidance from a rehabilitation trainer or physiotherapist.

Regular, conscious movement reduces the frequency of cramps in the long term.

The Role of Magnesium and Other Minerals

As mentioned earlier, magnesium is one of the key elements in muscle-nerve communication. Deficiency can indeed increase susceptibility to cramps, although it rarely causes cramps on its own. Magnesium creams applied externally can be particularly useful because they can be delivered directly to the affected area.

Benefits of magnesium cream:

• Localized relaxing effect
• Fast absorption
• Can be combined with herbal or menthol ingredients
• Particularly effective around trigger points

It is also important to maintain proper intake of potassium, sodium, and calcium, as together they regulate muscle contraction.

Summary

Preventing muscle cramps does not depend on a single method. The goal is not only to eliminate cramps but to bring the body into a state where it no longer needs this protective response. A harmoniously functioning musculoskeletal system is flexible, stable, and pain-free — and that is the true long-term solution.

An effective strategy consists of several elements:

1. Reducing strain on muscles and the nervous system with relaxation techniques and nerve glide exercises.
2. Strengthening weak or inhibited muscles after thorough assessment.
3. Conscious strengthening, mobilization, and stretching.
4. Using magnesium creams and replenishing minerals.
