Warming Up: Preparing Your Muscles for a Run

Should individuals wanting to engage in the exercise start with a warm-up and end with a cooldown to prepare the muscles for optimal performance and post-workout recovery?

Warming Up, Cooling Down

Warming up 5 to 10 minutes before exercise is beneficial for pumping blood to the muscles and preparing them for a run. Dynamic or active stretching and light aerobic activity are a few ways to warm up. This could be active stretching, such as walking lunges, brisk walking, or riding a stationary bike for a few minutes before running. However, individuals should avoid static stretches before running, as they can increase the risk of injury. The minimum length of time for an effective cooldown session is five minutes. Depending on the intensity of the workout, individuals may choose to extend that to 10 minutes.

Steps for a Running Warmup

• Do five to 10 minutes of light aerobic exercise to loosen up muscles.
• Walk briskly, march, jog slowly, or cycle on a stationary bike.
• Don’t rush.
• Perform dynamic stretches and movements during the warmup, including walking lunges, jumping jacks, or toe touches.
• Begin the run with a slow jog and gradually increase speed.
• Slow down if you run out of breath.
• This is part of knowing how fast you should run; starting too fast is a common mistake.
• Pay attention to posture and form.
• Ensure you are using the best technique before speeding up.

Warm Up Benefits

When warming up, the blood vessels dilate. The increased blood flow primes the muscles with oxygen and prepares them to perform at their best. Blood flow also increases the temperature in the muscles for enhanced flexibility. Allowing the heart rate to increase gradually is beneficial, instead of going full max heart output by jumping full speed into the running. (The American Heart Association, 2024)

Properly Cooling Down

At the end of the run:

• Cool down by walking or slowly jogging for five to 10 minutes.
• Breathing and heart rate should gradually return to normal.
• Drink water or an electrolyte-infused drink to rehydrate the body.

Benefits of a Cooldown

The cool-down keeps blood flowing throughout the body at a consistent level. Stopping immediately can cause light-headedness because heart rate and blood pressure can drop rapidly. Winding down slowly allows heart rate and blood pressure to fall gradually. The cooldown is also a good mental transition from the intensity and accomplishing the workout.

Before or After Stretching

Stretching evidence shows it doesn’t have the benefits once thought. Static stretching before, during, or after exercise has not been shown to prevent injury or delayed onset muscle soreness. (Herbert R. D., de Noronha M., & Kamper S. J. 2011) Stretching cold muscles is not recommended. However, there is some evidence that dynamic or active stretching after a warmup can benefit performance. Active stretching is done with exercises that take the muscles through their full range of motion and mimic the actions that will be done during the workout. (Van Hooren B., & Peake J. M. 2018)

Stretching After Running

Standard stretching includes the hamstring stretch, quad stretch, calf stretch, low lunge stretch, IT band stretch, butterfly stretch, hip and backstretch, arms and abs stretch, and triceps stretch. Tips for proper stretching:

Don’t Bounce

• Avoid bouncing, as this mimics pulling a rubber band back and forth. You want the muscle to stay stretched.
• Hold the stretch for 15 to 30 seconds.

Don’t Stretch Through Pain

• Don’t stretch beyond the point where tightness is felt in the muscle.
• Do not push through muscle resistance.
• Never stretch to the point of pain.

Stretch Whole Body

• Don’t just stretch the areas with tightness and/or soreness.
• Stretch the whole body equally to prevent injury.

Don’t Hold Your Breath

• Take deep breaths during the stretch.
• Stay relaxed and breathe in and out slowly.

If starting a new fitness routine, consult your healthcare provider to determine the optimal running warmups and stretching exercises.
