Psychiatry & Sports: Why Exercise Is Medicine for the Mind
Luís Altenfelder explains how physical activity stimulates the brain and outperforms medication alone.
In a conversation on XTREMMA Sports, psychiatrist Luís Altenfelder breaks down the vital link between physical movement and mental health. He explores everything from the neurochemistry of exercise to how sports help prevent psychiatric disorders.
The medical career of Luís Altenfelder began with an organic passion for sports. Coming from a family of physicians and managing ADHD and hyperactivity himself, he briefly considered studying physical education before committing to medical school. During his studies, his initial interest gravitated toward orthopedics or sports cardiology, fueled by a lifelong love for bicycle mechanics and tools. However, hands-on clinical rotations during his fifth and sixth years at Santa Casa de São Paulo redirected his path: while orthopedic routines often seemed confined to diagnostic imaging and anti-inflammatory prescriptions, psychiatry revealed the profound complexity of the human mind.
The disconnect between psychiatry and movement
When starting his shifts at psychiatric clinics as a newly minted doctor, Luís encountered a striking divide between mental health treatment and physical activity. Patient common areas were crowded with long lines for cigarettes, while spaces designated for exercise held little more than a lone pull-up bar and neglected dumbbells. In his view, sidelining physical exertion in clinical settings ignored one of the most effective ways to stimulate the brain and naturally trigger the release of key neurotransmitters like dopamine and endorphins.
Exercise as a therapeutic intervention
Back in 2008, medical literature rarely examined sports as a viable rehabilitation tool for non-athletes, but the current clinical landscape has shifted dramatically. Luís points to recent findings, including research published in the British Journal of Sports Medicine, demonstrating that structured 12-week exercise programs can yield outcomes up to 1.5 times more effective than antidepressant treatments alone. The metabolic demand produced by exertion stimulates biochemical pathways and reward responses that pharmaceutical drugs cannot replicate in the same manner.
Childhood habits and neurobiology
In conversation with host Shubi Guimarães, the psychiatrist highlighted that our relationship with movement is most impactful when fostered early in life. The cerebellum, an evolutionary brain region responsible for motor coordination, contains a substantial share of the human body's estimated 86 billion neurons. Early motor development—a core concept Shubi references from Nuno Cobra's book A Semente da Vitória—instills self-efficacy and a sense of physical achievement before a child even masters spoken language. Sustaining a consistent workout routine, such as the host's own regimen of roughly seven hours per week, builds enduring biological and cognitive reserves that protect against metabolic and psychiatric illness across a lifetime.
