For years, muscle cramps related to physical activity have been attributed mainly to dehydration or electrolytic imbalances. However, a growing amount of scientific data is questioning this explanation, indicating a often neglected cause: the mechanical characteristics of the sports fields.
According to Michael Hales, associate professor of physical education at Kennesaw State University, the state of the pitch can have a direct impact on neuromuscular effort and on the onset of cramps. And also well -hydrated and nourished athletes are not immune, if they are competing on non -familiar surfaces.
The link between playing and muscle cramps: what happens in the body
During intense exercise, the musculature can face an alteration in the normal balance between the nerve signals that regulate contraction and relaxation. Neuromuscular spindles, which detect the extension of the muscles, increase the activation frequency. At the same time, the inhibitory feedback of the Golgi tendon receptors – located at the point where the tendon joins the muscle – is reduced.
The result is a short circuit in nerve signals, which leads to an involuntary and supported muscle contraction, or the classic cramp.
The most recent studies show that the rigidity and elasticity of playing fields can accelerate this neuromuscular effort. If the body is not used to the characteristics of the soil, the musculoskeletal system tires more quickly, creating the ideal conditions for cramps.
In a study conducted by Hales and his team, a 13% difference emerged in muscle activity between runners who trained on fields with different mechanical properties. Another research has detected a 50% increase in the activation of the rear muscles of the thigh (Hamstring) performing the same exercises on different grassy surfaces.
In addition to specific sporting data, biomechanics for some time has been showing that the game surfaces directly influence muscle rigidity, joint load and amplitude of movement. All these elements affect muscle effort. In particular, the biarticular muscles – such as the femorals – are particularly sensitive to these variations, given their central function in rapid running and changes.
Prevent cramps with an adaptation aimed at the race surfaces
If the pitch can affect muscle effort so deeply, it is logical to think that adaptation to these surfaces can help prevent cramps.
An interesting idea proposed by scholars is the creation of regional databases with detailed information on the mechanical characteristics of the playing fields, for example in tennis or football. In this way, coaches and athletic preparers could change the training plans to simulate the race conditions and thus reduce the risk of cramps related to the novelty of the ground.
Let’s imagine, for example, a football team that usually trains on a soft field but that must then play a game on a much more rigid ground. If training do not take into account this difference, athletes could experience early fatigue and cramps. On the contrary, including specific exercises that simulate the muscle activation required by the tender field would allow a progressive adaptation of the neuromuscular system.
The same principle applies to basketball: a team accustomed to playing on new and rigid parquet could benefit from training sessions on more worn or cushioned flooring, similar to those that will be found in the opposing buildings.
The key is the gradual and systematic exposure to different surfaces, to get used to the body and reduce the risk of fatigue.
Towards a complete prevention: it is not enough to hydrate
Although hydration and nutrition remain fundamental for athletic performance, a more complete approach to the prevention of muscle cramps should also include biomechanical adaptation to game surfaces, the use of adequate footwear and the analysis of traction.
As technology is advanced, wearable biosensors will always be possible to monitor neuromuscular effort in real time. Combined with soil measurement tools and predictive models based on artificial intelligence, these devices could identify the individual risk of cramps even before they occur.
Coaches and preparers will therefore be able to adapt the workloads, make targeted replacements during the games or even modify, where possible, the characteristics of the pitch.
The prevention of cramps no longer passes only from drinking more water or eating more bananas. Thanks to research and new technologies, it is possible to anticipate the risks, customize training based on the field and protect the health of athletes, ensuring that they are ready and at most of the form when it really matters.
