Start Moving After 24-48 Hours Begin gentle movement 24-48 hours after concussion. Complete rest beyond this window delays recovery rather than helping it. Research shows that controlled sub-threshold exercise started within the first week accelerates symptom resolution by 4-5 days compared to strict rest (Leddy et al., 2019). Your first exercise isn't running or lifting weights. Walking for 10 minutes and gentle neck mobility represent appropriate starting points. The goal is activating your cardiovascular and neuromuscular systems at a level your healing brain tolerates. The key principle: exercise below the symptom exacerbation threshold. This is the intensity level where symptoms start to worsen. Stay below it, and exercise helps. Cross it, and exercise hurts. Finding Your Symptom Threshold Rate your symptoms on a 0-10 scale before exercise. During activity, symptoms should increase no more than 2 points. If they climb higher, stop and rest. Your threshold for today becomes your starting point. Example progression: If walking at a normal pace keeps symptoms below threshold for 15 minutes, that's your baseline. Tomorrow, try 18 minutes. Each day, add 10-20% duration or intensity if the previous day's exercise produced no lasting symptom increase. Track your responses in a simple log. Note the activity, duration, intensity, and symptom response during and 1 hour after. Patterns emerge quickly, showing you what works and what doesn't. Your threshold improves daily during normal recovery. What triggers symptoms today becomes comfortable within 3-5 days. This progressive tolerance expansion is your brain healing and adapting. Phase 1: Light Activity (Days 2-7) Walking: 10-20 minutes at conversational pace. Flat terrain, comfortable temperature, low-traffic areas. Heart rate stays below 50% of maximum (roughly 100-110 bpm for most adults). Neck mobility: Gentle cervical exercises twice daily. These require minimal metabolic energy while providing significant therapeutic benefit through improved blood flow and proprioception. Breathing exercises: Diaphragmatic breathing (4-second inhale, 6-second exhale) for 5-10 minutes. This activates parasympathetic nervous system pathways that support healing and reduce autonomic dysregulation common after concussion. Light stretching: Upper body and lower body stretches held 20-30 seconds. No positions that place your head below your heart, as this increases intracranial pressure. Neck Mobility Exercises for Phase 1 JME 1 Slow cervical rotation within pain-free range. 8-10 repetitions each direction. JME 6 Cervical flexion restores chin-to-chest range lost from protective guarding. JME 3 Lateral flexion releases unilateral neck tension common after head injury. JME 14 Chin tuck addresses suboccipital muscle hyperactivity driving headaches. Upper Body Exercises for Phase 1 JME 44 Shoulder circles maintain joint mobility with minimal exertion. JME 42 Gentle shoulder movement prevents deconditioning during restricted activity. JME 151 Thoracic side bending keeps the mid-back mobile during reduced activity phases. JME 164 Seated thoracic rotation supports spinal function without balance demands. Access Phase 1 exercise protocols designed specifically for safe early concussion recovery with simplmobility. Phase 2: Light Aerobic Exercise (Days 7-14) Once Phase 1 activities produce no symptom increase for 2-3 consecutive days, progress to light aerobic exercise. Stationary cycling: 15-20 minutes at low resistance. Heart rate reaches 50-60% of maximum (110-130 bpm). Cycling removes balance demands present in walking or running. Swimming: Easy laps for 15-20 minutes. Water provides a calming sensory environment. Avoid diving, flip turns, and underwater swimming. Extended walking: 25-40 minutes at a brisk pace. Add gentle hills if flat walking is comfortable. Expanded mobility work: More demanding neck exercises, shoulder strengthening with light resistance, thoracic mobility drills. Include balance exercises if vestibular symptoms are improving. Phase 3: Sport-Specific Training (Days 14-21) Heart rate reaches 60-80% of maximum. Sessions last 30-45 minutes. This phase tests your brain under increasing metabolic demand. Running: Start with jogging intervals (jog 3 minutes, walk 2 minutes) progressing to continuous running. Monitor symptoms closely during and after. Resistance training: Bodyweight exercises and light weights. No heavy loads, no breath-holding, no head-below-heart positions. Focus on controlled movements with normal breathing. Sport-specific drills: Without contact. Footwork, ball handling, position-specific skills at 70-80% intensity. Test your cognitive processing under sport-related conditions. Phase 4: Non-Contact Training (Days 21-28) Full training intensity without body contact. Team drills, practice sessions, and conditioning at pre-injury levels. Your healthcare provider should assess readiness for this phase. Phase 5: Full Contact and Return to Play (Day 28+) Only with medical clearance after completing all previous phases without symptom increase. One symptom-free day at each phase before advancing. The Buffalo Concussion Treadmill Test This validated protocol identifies your exact symptom threshold. You walk on a treadmill with increasing speed and incline while monitoring heart rate and symptoms. The heart rate at which symptoms worsen becomes your exercise ceiling. Treatment involves exercising at 80% of this threshold heart rate for 20 minutes daily. As your brain heals, the threshold rises, allowing progressive intensity increases. This approach produces faster recovery than rest-based protocols (Leddy et al., 2019). If you don't have access to formal testing, use perceived exertion. Aim for "light" to "somewhat hard" effort (3-5 on a 1-10 scale). If you are breathing hard enough that conversation becomes difficult, you've exceeded your threshold. Common Mistakes with Post-Concussion Exercise Doing too much too soon. Athletes and active individuals commonly push past symptoms because they feel restless. One aggressive session sets recovery back 3-7 days. The fastest path to full activity is patient, graduated progression. Complete avoidance of exercise. Fear of symptom provocation keeps some people inactive for weeks. This deconditioning creates its own symptoms that overlap with concussion, extending perceived recovery time. Skipping phases. Each phase builds capacity for the next. Jumping from walking directly to running risks overwhelming your brain's recovered capacity. Follow the progression even when you feel ready to skip ahead. Ignoring symptom signals. Exercise through worsening symptoms is counterproductive. Unlike athletic training where "pushing through" builds fitness, pushing through concussion symptoms damages recovery. Follow evidence-based exercise progression with simplmobility's structured concussion recovery protocols that advance at your individual pace. FAQ Does exercise actually speed up concussion recovery? Yes. Controlled sub-threshold aerobic exercise started within the first week accelerates recovery by 4-5 days compared to rest alone. Exercise improves cerebral blood flow regulation, supports neuroplasticity, and reduces autonomic dysfunction. What heart rate should I stay below during concussion recovery? During Phase 1 (days 2-7), stay below 50% of max heart rate (100-110 bpm). Phase 2 (days 7-14) allows 50-60% (110-130 bpm). Phase 3 (days 14-21) permits 60-80% (130-155 bpm). These are guidelines. Your symptom response overrides any heart rate target. What if exercise makes my symptoms worse? Stop the activity, rest until symptoms return to pre-exercise levels, and reduce intensity or duration by 25-50% next session. If symptoms consistently worsen with any exercise, consult a concussion specialist for evaluation of underlying issues like cervical dysfunction or vestibular problems. Is yoga safe after concussion? Gentle yoga without inversions (head-below-heart positions) is appropriate during Phase 2. Avoid hot yoga, power yoga, and advanced poses requiring complex balance until Phase 4. Restorative yoga with simple positions supports recovery from the early stages. References Leddy, J. J., et al. (2019).
