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.

For individuals about to engage in physical activity or exercise, how does warming up the body help prepare for the work ahead?
Central Nervous System Activation
A proper warm-up before physical activity or working out prepares the mind and body to reduce risks of injury, mentally and physically transition to physical activity work, and enhance performance. A well-designed warm-up also primes the central nervous system/CNS for activity. The central nervous system transmits messages to the muscles to prepare them for action. Central nervous system activation increases motor neuron recruitment and engages the sympathetic nervous system so the body can better handle the physical stressors. The process may seem complex, but priming the nervous system is as simple as warming up with light aerobic activity before getting into more explosive movements.
CNS
The CNS consists of the brain and spinal cord. This central communication system uses another part of the nervous system known as the peripheral nervous system or PNS to transmit and receive messages throughout the body. The PNS is connected to the entire body and the brain and spinal cord (CNS).
Nerves run throughout the body, receiving signals from the CNS to the muscles, fibers, and organs, transmitting various information back to the brain. (Berkeley University. N.D.)
There are two types of systems within the peripheral nervous system – somatic and autonomic.
Somatic nervous system actions are those controlled by the person through voluntary actions like choosing to pick something up.
Properly preparing the body for an intense strength training session or other physical activity needs the correct messages to be sent through the autonomic nervous system.
Parasympathetic and Sympathetic States
The autonomic nervous system consists of two subcategories, which are parasympathetic and sympathetic.
The sympathetic nervous system helps the body get ready to face stress which includes physical stress. (R. Bankenahally, H. Krovvidi. 2016)
The fight, flight, or freeze response describes the sympathetic nervous system’s aspect.
The parasympathetic nervous system is responsible for relaxation and de-stressing.
Individuals are recommended to perform a few calming movements and actions after a workout to return the body to a parasympathetic state. This can be:
Activating the CNS can increase performance and prevent injuries. The process wakes up and alerts the body for the activity. Individuals are recommended before beginning a training session, to communicate to the body about the physical stress it is about to endure and to prepare for the work ahead. This is a concept known as post-activation potentiation/PAP. (Anthony J Blazevich, Nicolas Babault. 2019) PAP helps increase force and power production, which enhances physical performance.
Whenever an individual trains, the brain adapts and learns what the body is doing and the purpose of the training.
Muscle memory describes this interaction.
Individuals who have started up a new strength training routine or after an extended break report feeling awkward for the first few sessions, or even weeks, depending on their experience. (David C Hughes, Stian Ellefsen, Keith Baar, 2018)
However, after a few sessions, the body is more adept at performing the movements and ready to increase resistance, repetitions, or both.
This has to do with the neural drive and muscle memory than it has to do with true potential physical abilities. (Simon Walker. 2021)
The first step is a general warm-up that should use large muscle groups and be of low intensity so as not to exhaust the body before beginning the actual training. General warm-up benefits central nervous system activation and the entire body include: (Pedro P. Neves, et al., 2021) (D C. Andrade, et al., 2015)
Increases blood circulation.
Assists the release of oxygen from hemoglobin and myoglobin.
Warms the muscles, so they contract more effectively.
Increases nerve impulse speed.
Increases nutrient delivery.
Lowers joints’ resistance through increased synovial fluid/joint lubrication.
Increases joint range of motion.
Improves joint resiliency.
Removes metabolic waste quicker.
Reduces risk of injury.
A general warm-up can be simple as any aerobic activity will work. This can include:
Performing bodyweight movements – light jumping jacks or jogging in place.
Treadmill
Rowing machine
Stair climber
Elliptical trainer
It is recommended to use the rating perceived exertion scale/RPE to determine the general warm-up effort. An exertion rating of between 5 to 6 is equivalent to moderate walking or a slow jog. Individuals should be able to speak clearly without taking a pause.
Try this strategy before the next workout to see increased performance and reduced injury risks.
