1. Recurring keywords / key ideas

• Brisk walking 3.0-4.5 mph vs strolling <2.5 mph
• Metabolic threshold
• Caloric burn delta
• Mortality risk reduction (~20% vs ~4%)
• Aerobic heart rate zone
• Arrhythmia risk reduction
• Physiological stress and demand
• Session dose equivalence (15 min brisk ≈ hours of stroll)
• Cardio adaptations
• Mechanism depth

2. Core / novel / atypical ideas

• Speed crosses a threshold; same duration is not the same intervention.
• Quantified “extra” table makes the casual vs brisk distinction visceral.
• Critical claim: ~15 minutes brisk can match mortality benefit needing ~3 hours stroll (per cited synthesis).

3. Context and flow

08 May deep research note. Primary physiology brief; cognitive sibling and 07 May Guide are related. Fits behavioral activation / movement practice week.

4. Publishing angles

• Mode: Authority article
• Why: Mechanism + quantified comparison, high utility.
• Angles:
  • Why brisk is not “just walking faster for vanity”
  • Dose table for people who only have 15-30 minutes
  • Pair with cognitive effects piece as two-part series
