Doctors Now Prescribe Exercise for Depression

A groundbreaking editorial in the Journal of Sports Medicine and Physical Activity (November 2024) by Dr. Nicholas Fabiano and colleagues has transformed how we think about exercise prescription. Moving beyond simple encouragement to “be more active,” their research presents a structured medical approach to using physical activity for depression treatment.

The Medical Model of Exercise Prescription

Just as physicians carefully prescribe medications with specific dosages and frequencies, exercise can – and should – be prescribed with similar precision. Dr. Fabiano’s research shows that like medication adherence, developing physical activity habits requires structured support and careful monitoring.

The FITT Framework for Depression Treatment

Frequency

  • Optimal: 3-5 sessions per week
  • Starting point: Even once weekly shows benefits
  • Progressive increase based on response

Intensity

Using the “talk test” method:

  • Low: Conversation and singing possible
  • Moderate: Can talk but not sing
  • Vigorous: Only few words possible
  • Note: Moderate to vigorous intensity recommended for depression, but starting lower is acceptable

Time

  • Target: 45-60 minutes per session
  • Initial sessions: 10-30 minutes
  • Key strategy: “Commit 10” – start with just 10 minutes

Type

All show effectiveness:

  • Aerobic activities
  • Resistance training
  • Mind-body practices
  • Combined approaches

The Science Behind Movement

Exercise’s impact on depression involves multiple mechanisms:

  • Muscle-released myokines
  • Increased brain-derived neurotrophic factor (BDNF)
  • Improved stress response
  • Enhanced sleep regulation
  • Better cognitive function

Professional Support: Essential Elements

Supervised activity enhances both adherence and benefits through:

  • Structured group programs
  • Professional exercise guidance
  • Regular progress monitoring
  • Adaptation based on response

Patient Empowerment

Success relies on:

  • Patient involvement in activity selection
  • Collaborative goal setting
  • Regular feedback and adjustment
  • Celebration of progress

Breaking Down Barriers

Common obstacles and solutions:

  • Low energy: Start small, build gradually
  • Time constraints: Break activities into shorter sessions
  • Limited access: Home-based options
  • Lack of experience: Professional guidance
  • Motivation: Group support and tracking progress

Looking Forward

Part 2 of this series will explore the precise measurement of exercise intensity using the METs (Metabolic Equivalent of Task) system, providing concrete guidelines for achieving optimal health benefits across multiple systems.
