When intensity increases
An easy jog and a hard sprint place different demands on the body. At very high intensity, the concentration of hydrogen ions in the muscle can increase; the pH level drops. This change is one of several factors that play a role in fatigue.
The body's own buffers absorb hydrogen ions. Transport processes help move them out of the active muscle cells. This happens during exertion and should not be equated with a permanently "acidic body."
Buffering and regeneration have different roles
While buffers limit rapid changes, the time after training is about replenishing stores and renewing stressed structures. With appropriate training stimuli and sufficient recovery, the body can adapt over several training cycles.
That is why it is worth planning for exertion and the time that follows together. A single measure cannot handle every task: food provides energy and building blocks, fluids replace losses, and sleep and breaks provide room for recovery.
Where minerals come in
Minerals are needed even after training is over. Magnesium contributes to electrolyte balance. Magnesium and calcium contribute to normal muscle function. Together with phosphorus, they contribute to normal energy metabolism.
When sweating heavily, water, sodium, and chloride are lost in particular. This immediate replacement and the supply of magnesium or calcium are different parts of sports nutrition. The appropriate amounts depend on factors such as duration, intensity, heat, and your overall diet.
Assessing your own exertion
Do not just look at a single session. How often do you train? How much time is there in between? Are you eating and drinking according to your exertion? These questions turn the buzzword "regeneration" into a concrete plan.
More minerals than needed do not automatically mean more progress. The key is an appropriate supply. You can find the basics and the individual functions of minerals on our regeneration page.
