Start Strong, Finish Safe: the Power of Warm-Ups and Cool-Downs

Abstract

Have you ever wanted to feel better before starting a physical activity? Or maybe you have experienced the need to recover a little bit after playing a sport or doing some form of exercise? Understanding how to do a proper warm-up before physical activity and how to cool down properly after physical activity are two important ideas that will help you feel your best when being active. A proper warm-up will help you get ready to perform at your best, and a cool-down will help your recovery process. Preparing your body for physical activity and recovering after physical activity are both very important for your fitness, health, and overall wellbeing. Do you want to learn more about how to warm up and cool down so you can feel better when you participate in physical activities? Keep reading for more information on these topics, and try out some of the examples that we provide!

Feeling Your Best Before and After Physical Activity

It is important that you do a proper warm-up before you start any type of physical activity. This allows your body to process what is about to happen next! Warming-up helps your body get moving so you do not just jump right into the activity, which could lead to injury. Cooling-down is just as important and is something that should be practiced after you have completed your physical activity. Cooling-down helps the body calm down a bit and relax back to its resting state. You can achieve this by doing some fun stretches after your physical activity.

What is a Warm-Up?

A general warm-up should take about 5- to 10- min at a light to moderate intensity and should include some dynamic movements. Dynamic movements should take your joints through their full range of motion and should be specific to the physical activity you are about to do [1]. That means if you are going to run, you should include lower-body movements and begin to raise your heart rate during the warm-up, to simulate the task ahead. As your warm-up progresses, the movements you choose should be increasingly similar to the physical activity you are about to do. For example, if you are going to play baseball you may begin your warm-up with upper body stretching and dynamic movements, and by the end of the warm-up you should progress to fully throwing the ball, since that movement is specific to the activity you are about to play! By the end of a warm-up, you should feel that you are ready to play and perform at your best!

Another way to ensure that you are warming up correctly is to use the acronym R.A.M.P., which stands for Raise, Activate, Mobilize, and Potentiate (Table 1) [2].

Raise Raise your heart rate by doing more challenging and faster movements, which helps get your body ready to move.
Activate Engage the muscles that will be working during your activity.
Mobilize Practice the moves that you will do in your activity, like running, jumping, or twisting.
Potentiate Warm your muscles up more intensely as the warm-up progresses, so you are fully ready to start your activity.

The Importance of Warming Up

Including a warm-up before your physical activity is extremely important. A warm-up has many unique positive features. While the primary goal of a warm-up is to get you physically ready for your activity, it can also help prepare you mentally. Bodily adjustments that occur while performing a warm-up include increasing blood flow to the active muscles, raising body temperature and causing you to sweat, helping your body make energy faster, and improving how far you can bend, reach, or twist.

If a warm-up is avoided or is too short, your body will not be prepared for physical activity. Active muscles will not feel loose and ready for the movements, and your blood will not be flowing quickly enough to fuel the muscles that are working hard during the activity. This could cause pulled muscles… ouch! Not only that, but you might also even experience a headache because your blood flow speeds up suddenly.

Try This Warm-Up!

Before you start your next physical activity, complete the 5- to 10-min warm-up shown in Figure 1. Remember, it is important to increase your heart rate so that you are ready for your activity. You can do this by running, biking, or doing some jumps. Complete each exercise, going through a comfortable range of motion, while taking some running steps in between which move. Be sure to end your warm-up by doing the specific movements that you will be doing for your physical activity.

Each exercise has a brief instruction and highlights proper form.

What is a Cool-Down and Why is it Important?

A cool-down is an activity that involves low- to moderate-intensity movements performed after physical activity, which include static stretches for the muscle groups that were just exercised. You should hold each stretch for about 30 s and repeat each stretch about 2–3 times. While you are stretching, be careful that you do not have any pain—you do not want to feel like you are overstretching but should be a little bit challenging.

Doing a cool-down after physical activity has many benefits. Importantly, stretching after your activity can help reduce how sore you will feel. Cooling down also allows your heart rate to slow and return to its normal value [3]. Cooling down is very important as you get older because it can help reduce the risk of injury. The fewer injuries you suffer, the more you can play! If you stop your physical activity too quickly and do not do a cool-down, you may begin to feel sick or lightheaded, or even pass out, so it is important to take cooling down seriously.

Try This Cool-Down!

After your physical activity, give the cool-down in Figure 2 a try and see how you feel. It is key to bring your heart rate down after your activity, and to hold the stretches for 20–30 s for 2–3 rounds. Make sure to not bounce as you hold the posture and remember it should not be painful! Bouncing during stretching may cause further injury and not be comfortable.

Wrapping It Up

Completing a warm-up before you engage in your physical activity has many benefits. As you get older, warming up is even more important, to ensure you are ready for your physical activity. This can decrease any chances of getting hurt and ensure that your body is adjusting to the upcoming work. Cooling down helps your body get back to a normal resting level. A cool-down is important because you do not want to feel out of breath or extremely sore after the activity, which is why it is important to stretch.

Physical activity is very important for your health and wellness, being sure you are practicing safe movements and making sure your body can gear up for the activity by warming-up and being sure you stretch afterwards and cool-down are key for doing physical activity at your best!
