A step-by-step return-to-play protocol helps people slowly increase physical activity while watching for worsening symptoms. The process is designed to support concussion recovery and help athletes return safely to the sports they love.

“Every concussion is different,” says Brian M. Babka, MD, a sports medicine physician at Northwestern Medicine. “A step-by-step return helps people recover safely and build back to full participation.”

Why Returning to Competition Too Soon Can Be Risky

A concussion is a mild traumatic brain injury that affects how the brain functions. Concussion symptoms may include:

• Headaches
• Dizziness
• Balance problems
• Fatigue
• Difficulty concentrating
• Memory problems
• Sensitivity to light or noise
• Changes in mood

While most people recover fully, healing doesn’t always happen in a straight line. Symptoms can improve, then temporarily return when physical activity, schoolwork or other mental activities increase.

Returning to sports too soon may delay recovery and increase the risk of another concussion before the brain has fully healed.

A second head injury during this time may lead to a longer recovery and mean more time away from sports, school, work and other activities. That’s why athletes should never return to play on the same day a concussion is suspected.

“Our efforts to educate and inform parents, coaches, administrators and clinicians about concussions are paying off. Use common sense and err on the side of caution,” says Dr. Babka. “Any suspected head injury should be taken seriously: When in doubt, keep them out. That means no same-day return to play.”

Seek immediate medical attention or call 911 if a person develops worsening headaches, repeated vomiting, increasing confusion, seizures, weakness, slurred speech or difficulty waking up after a head injury.

Recovery Starts Before Return-To-Play

Healthcare professionals often recommend a short rest period during the first 24 to 48 hours after a concussion. After that, light physical activity that does not significantly make symptoms worse is often encouraged.

“Years ago, people were often told to avoid activity completely after a concussion,” says Dr. Babka. “Today, we know that light exercise that stays below the point where symptoms significantly worsen can be an important part of recovery. This approach is sometimes called active rehabilitation.”

Before starting a return-to-play progression, athletes should:

• Be evaluated by a physician.
• Be making steady progress.
• Be tolerating school, work and other daily activities.
• Receive guidance on when it’s appropriate to begin increasing physical activity.

For student-athletes especially, returning to learning often comes before returning to play.

What Is the Return-to-Play Protocol?

A return-to-play protocol is a plan that gradually increases physical activity in stages. Each step allows the athlete and care team to watch for symptoms.

While exact protocols may vary by organization, most follow a similar progression based on widely accepted concussion guidelines. Athletes should advance to the next stage if symptoms do not return or worsen during or after activity.

“In most cases, each step should take at least 24 hours, and steps should not be combined,” says Dr. Babka. “This allows time to monitor for symptoms and helps ensure the athlete is ready to progress safely.”

Because each stage takes at least 24 hours, most athletes need several days to progress through the protocol once they are ready to begin. Some people may need weeks or longer.

Step 1: Light aerobic activity

The first stage focuses on gently increasing heart rate through light aerobic exercise.

Examples include:

• Walking
• Light jogging
• Stationary biking

The goal is not to improve fitness. Instead, the focus is on determining whether the brain can handle mild physical activity without making symptoms worse.

Step 2: Moderate exercise

If symptoms do not return, the person can move on to more challenging activity.

Examples include:

• Moderate jogging
• Higher-intensity stationary biking
• Light strength training

At this stage, athletes begin doing more body and head movement while continuing to avoid contact.

Step 3: Heavy, noncontact activity

The next step involves sport-specific exercise without the risk of hits from other players.

Examples include:

• Running drills
• Agility exercises
• Sprinting
• Noncontact practice drills
• Regular strength-training activities

Athletes are training harder, but they still avoid situations where another player could hit their head. Those who play contact sports should not yet take part in contact-training drills.

Step 4: Full practice participation

Once cleared by a healthcare professional, athletes can join supervised practice activities, including contact if their sport requires it.

This stage may include full-contact practice and supervised contact training drills for athletes who play contact sports. It helps coaches and athletic trainers see how an athlete handles the physical and cognitive demands of practice before competition.

Step 5: Return to competition

Athletes can return to competition after successfully completing all previous stages without symptoms returning.

For many athletes, this progression takes at least several days. Some may require significantly longer depending on their symptoms, medical history and recovery timeline. A gradual approach reduces the risk of setbacks and helps ensure athletes are ready for full participation.

What Happens if Symptoms Come Back?

If concussion symptoms return during any of these steps, it may be a sign that the athlete has advanced too quickly.

Common symptoms that can reappear include:

• Headaches
• Dizziness
• Fatigue
• Difficulty concentrating
• Sensitivity to light or noise

If symptoms occur, the athlete should stop the activity and notify their healthcare professional, athletic trainer or coach. In many cases, they will need to return to an earlier stage and wait for symptoms to improve before advancing again. Monitoring for symptoms is one of the most important parts of the return-to-play process.

Do not try to “push through” concussion symptoms. Feeling worse during activity is a sign that the brain may need more time to recover.

Parents and Coaches Play an Important Role

Young players are often eager to get back in the game. Some may minimize or fail to report symptoms because they do not want to miss practices or games.

Parents, coaches, athletic trainers and physicians should maintain open communication throughout the recovery. Monitoring symptoms, encouraging honest reporting and supporting their return to activity can help prevent returning to play too soon.

“We all need to work together to help a student-athlete recover,” says Dr. Babka. “Keeping a student from school can cause anxiety, depression and frustration from trying to catch up on assignments, so using a step-by-step approach is imperative.”

Play It Safe for a Strong Return

Missing practices or games can be frustrating for athletes. But recovering fully from a concussion is more important than rushing back into competition.

A structured return-to-play plan gives the brain time to heal while helping people rebuild confidence and fitness along the way.

With help from sports medicine specialists and a careful step-by-step approach, most athletes can safely return to competition and the sports they love.
