Most runners make the same mistake: they run at full speed as soon as they get out of the house. The result? Sore muscles, burning knee pain, and weeks of forced rest. Discover why warming up before a run is a must, not a waste of time.
Every year, thousands of runners – both beginners and experienced – ruin their season with a torn Achilles tendon, iliotibial band syndrome, ankle sprains, or knee pain, collectively known as “kneecap.” The common point of most of these injuries? The runner has not warmed up properly.
Warming up is not just waving your arms, it is a full, physiologically based body preparation to extreme mechanical stress. When you run, each step puts a force on your joints and muscles that is two-to-three times your body weight.
A cold muscle is stiff., poorly ventilated and biomechanically unsuitable for such a blow. It's like a cold rubber band that you pull - instead of stretching, it snaps.
Why static stretching before running is harmful
The first and most common mistake! Runners sit on the ground before running and start statically stretch cold musclesStatic stretching (holding a position for 30 seconds or more) on a cold muscle actually reduces its explosive power and neuromuscular reflexes for the next 30 to 60 minutes.
Research has clearly shown that static stretching before intense aerobic exercise increases the risk of injury and reduces a runner's performance. Judge static stretching ONLY after a run, when the muscles are warm and full of blood.
Phase 1: Cardiovascular activation (3 to 5 minutes)
Warm-up should begin with activation of the circulatory system, not muscles. Start by walking briskly or jogging very slowly (a pace at which you can easily speak a full sentence).
During this time, your heart gradually increases blood flow, muscle tissue temperature begins to rise, the synovial fluid in the joints (a natural lubricant) is activated and distributed over the joint surfaces. Skipping this step is like starting a cold engine at full speed - wear is inevitable.
Phase 2: Dynamic joint movement (3 minutes)
Once the circulatory system is activated, switch to dynamic joint mobilizationThese are not static stretches, but controlled movements through a full range of motion.
It includes ankle rotations (10x in each direction), hip rotations, high steps with the tip of the foot up (which activate the front of the thigh and patella), and side lunges while walking. The goal is to lubricate every joint, which will be under load during running, with enough synovial fluid.
Phase 3: Activation exercises for stabilizer muscles (3 minutes)
Most runners forget about the muscles that are not visible but are crucial for preventing injuries.
The gluteus muscles are the most important stabilizers during runningWeak glutes force the knees to internally rotate with every step, which directly leads to injury.
Before running be sure to perform 15 side steps with a mini elastic band around your ankles, 15 glute bridges and 10 single squats on each leg. This activation “turns on” the muscles that will protect your knees and hips throughout the run.
Phase 4: Running with increasing intensity (2 minutes)
The last phase is gradual increase in paceStart at 30% of your target speed and increase it every 30 seconds to your work pace.
This is a signal to the nervous system to activate right motor units and movement patterns. Your body will enter the work pace prepared, not shocked.
A ten-minute warm-up is not a waste of time, it is an investment in the weeks and months that will allow you to train without any problems. Every injury that you prevent with proper preparation saves you weeks of forced rest, expensive physiotherapy and frustration.
