What happens during a training session?
During exercise, you strain your muscles, tendons, and joints. That is precisely the intention. You create small damages in the muscle tissue, so to speak, and engage your energy systems.
After the training, your body must:
- Repair muscle tissue
- Replenish energy reserves
- Remove waste products
- Regulate inflammatory responses
- Prepare the body for the next exertion
It is only during this recovery process that you ultimately become stronger, faster, or fitter.
No progression without recovery
Many athletes believe that more training automatically leads to better performance. In reality, training and recovery are inextricably linked.
When recovery is insufficient, the likelihood of:
- Fatigued legs
- Decreased performance
- Prolonged muscle soreness
- Overload
- Injuries
It is precisely the balance between exertion and recovery that determines whether you make progress.
Why recovery is often underestimated
A training session feels productive. You've sweated, covered miles, or completed a demanding schedule. Recovery, on the other hand, often feels passive.
Nevertheless, sufficient sleep, nutrition, hydration, and recovery measures are at least as important as the training itself.
Many runners recognize it: two identical training sessions can feel completely different. Often the difference is not in the training, but in how well the body had recovered prior to that session.
