The crucial role of hydration in muscle function and recovery

Hydration is not just about drinking enough water. It is a fundamental part of how your muscles perform and how well you recover afterward.

Water is the body’s primary transport medium. It delivers nutrients, including glucose, electrolytes and amino acids, to your muscles. Those nutrients are what muscle contraction, energy production and repair depend on.

Water also flushes out metabolic waste that builds up during exercise. Clearing that waste efficiently supports the recovery process, so you can return to training sooner and with less discomfort.

What dehydration does

Dehydration works against both of those jobs.

When you are dehydrated, the body struggles to deliver enough nutrients to the muscle. Performance drops. Susceptibility to injury goes up.

Waste clearance suffers too, which is associated with cramping, stiffness and soreness that lingers. That extends your recovery time and disrupts your training.

Practical hydration

• Hydrate throughout the day, not only around workouts. Thirst is already a sign of mild dehydration.

• Drink before, during and after training, and scale your intake to the intensity and duration of the session.

• Consider electrolytes for long or intense efforts, or when you sweat heavily.

Hydration will not fix a restricted tissue, and it is not a substitute for appropriate treatment or movement. But dehydrated tissue does not respond as well to either, which is why I ask about it.
