Exercise and Cognitive Performance for Board Exam Reviewers

Exercise and Cognitive Performance for Board Exam Reviewers

Exercise is one of the most underused study aids. Regular activity supports memory, focus, sleep and stress management, which makes it part of good review, not time taken away from it.

Why exercise helps cognition

Research points to several benefits:

• Aerobic exercise raises BDNF (brain-derived neurotrophic factor), a protein involved in learning and memory
• Regular exercise tends to improve sleep quality, and sleep is when memories consolidate
• It helps with stress and anxiety
• It improves cardiovascular health, including blood flow to the brain
• It lifts mood

What counts as exercise

Doesn't need to be gym-intensive:

• 30-min brisk walk
• 20-min jog
• Stationary bike
• Bodyweight circuits at home
• Swimming
• Dance

Goal: the World Health Organization recommends that adults get at least 150-300 minutes of moderate aerobic activity a week (for example, 30 minutes on 5 days), plus muscle-strengthening on 2 or more days.

Realistic schedule for reviewers

Standard reviewer day:

Two short walks + one focused workout = sufficient.

When to exercise

Best timing:

• Morning (energizing for the day, doesn't affect sleep)
• Lunch break (resets focus for afternoon)
• Late afternoon (before dinner, doesn't disrupt sleep)

Avoid:

• Hard workouts close to bedtime (they can make it harder for some people to fall asleep)
• After heavy meals
• During scheduled focused study sessions

What about gym membership?

Optional. Plenty of options without:

• Walks or runs in your neighborhood
• Bodyweight workouts at home
• YouTube workout videos
• Stationary bike at home (one-time cost)

If you have a gym membership, use it. If you don't, don't let that stop you.

Specific exercises that help

Cardiovascular (most important for cognition)

• 30-min brisk walk daily
• 20-min jog 3x/week
• Cycling
• Swimming

Strength training (1-2x/week)

• Push-ups, pull-ups, squats
• Bodyweight circuits
• Yoga (counts as both flexibility + strength)

Flexibility

• 10-min stretching daily
• Yoga 2-3x/week

Mind-body

• Yoga
• Tai chi

Common mistakes

• Skipping exercise entirely "to save time" — false economy
• Over-exercising (2+ hours daily) — fatigues you for study
• Exercising right before exams — light only, no exertion
• Treating exercise as separate from study — it's part of effective prep

Exercise during exam week

In the week before exam:

• Continue light exercise (walks)
• Avoid new intense workouts (injury risk)
• Maintain sleep + diet routines

Day of exam:

• Light walk OK (20 min max)
• No strenuous exercise
