PTSD and Exercise

Exercise is a potent, evidence-based tool for managing PTSD. It regulates stress hormones, improves sleep, and promotes neuroplasticity.

The physiological and psychological pathways behind these benefits are well-documented:

Stress Hormone Regulation: Trauma leaves the body trapped in a chronic "fight or flight" state, with consistently high adrenaline and cortisol levels. Physical activity forces the body to process and flush these hormones out of the system.

Brain Health (Neuroplasticity): Aerobic exercise increases brain-derived neurotrophic factor (BDNF), which improves emotional regulation and memory processing.

Symptom Reduction: Regular movement diminishes the severity of depression and anxiety, which frequently co-occur with PTSD.

Sense of Control: Structured activity—whether it's running, cycling, or lifting weights—gives individuals a sense of autonomy over their own bodies.

Hereditary Spastic Paraplegia (HSP) is a group of hereditary, degenerative, neurological disorders that primarily affect the upper motor neurons. Commonly in Hereditary spastic paraplegia, upper motor neurons slowly degenerate so the muscles do not receive the correct messages, causing progressive spasticity (increased muscle tone/stiffness) and weakness of the legs. This leads to difficulty walking.

Studies have overwhelmingly shown the benefits of Strength Training in treating HSP. In becoming stronger Nick has maintained his range of motion, been able to perform more activities of daily living, and significantly improved his overall quality of life.

HSP is very rare and current knowledge is limited, but it thought to be progressive in nature. Nick was diagnosed with HSP in 2014, yet maintaining his strength/mobility, along with a positive attitude, has resulted in very little progression of the condition in the past 7 years.

Cerebral palsy (CP) is a group of disorders that affect a person's ability to move and maintain balance and posture. All physicians, researchers, and practitioners now recommend Strength training to help manage CP. The benefits are numerous, and the evidence is overwhelming.

All forms are Strength training are hugely beneficial for people with Cerebral Palsy. When possible, we try to recruit the maximum amount of muscle mass via multi-joint exercises e.g., Squat, Deadlift, Bench Press. Let’s firstly look at the Squat at its proven benefits for people with CP:

• Increased Strength (Back, Core, Hips, Legs)
• Increased Muscle Mass
• Decreased Body Fat
• Increased Bone Density
• Improved Cardiovascular Health
• Improved Inter-Muscle Coordination and Neuromuscular
Learning
• Improved Balance and Coordination
• Improved Gross Motor Skills
• Increased Mobility and Flexibility
• Improved Mental Health
• Sense of Mastery and Achievement
• I really could go on…….

Brian is a 54-year-old man with Cerebral Palsy. Here he is Squatting 55kg with perfect form.
