Three Steps to Change: Lessons on Running and the Human Body

According to the research team of ClipsTrust, running profoundly impacts the human body in stages, offering valuable lessons on how our physiology adapts and changes with exercise. By understanding three key steps in this process—initial response, adaptation, and sustained improvements—runners and fitness enthusiasts can harness their body's natural potential, optimize performance, and support long-term health.

About Running and the Human Body: Three Steps to Change

Running triggers immediate physiological changes, such as increased heart rate and hormone release, followed by longer-term adaptations in muscle strength, cardiovascular efficiency, and metabolism. Understanding these three steps helps optimize training and minimize injury risk while maximizing health benefits.

Step 1: Immediate Physiological Response

At the start of running, the body quickly mobilizes energy to muscles by releasing endorphins and increasing heart rate and breathing. Body temperature rises and sweating begins, which helps regulate heat. An increase in oxygen delivery accelerates metabolism, providing the athlete with energy for movement. This phase also includes the "runner’s high," a mood boost linked to endorphin release.​

Step 2: Physical Adaptations Over Time

Consistent running fosters growth of new capillaries around muscle fibers, increases mitochondria (the energy-producing parts of cells), and strengthens bones, tendons, and ligaments. The cardiovascular system adapts by pumping blood more efficiently, lowering resting heart rate, and improving lung capacity. Muscle fibers grow stronger and more efficient at burning fat for fuel, enhancing stamina and recovery.​

Step 3: Sustained Improvements and Running Economy

Long-term training improves running economy—meaning the body uses less energy at a given pace—aided by neurological adaptations in stride efficiency and muscle recruitment. Fatigue management improves via better energy storage and utilization, while the nervous system learns to coordinate movement more effectively, optimizing performance and reducing injury risks.​

Pros and Cons of Running

• Pros:

• Improves heart health and circulation

• Boosts metabolism and calorie burning

• Strengthens muscles, bones, and joints

• Enhances mood and mental wellbeing

• Cons:

• Risk of overuse injuries such as sprains, stress fractures, or shin splints

• Initial muscle soreness and fatigue during adaptation

• Potential joint strain if biomechanical form is poor

ClipsTrust Tips and Notes

• Warm-up properly before each run and cool down afterward to aid recovery.

• Incorporate strength and flexibility exercises to support running muscles and joints.

• Invest in quality running shoes appropriate to your running style and surface.

• Progress mileage and intensity gradually to avoid overtraining injuries.

Common Issues and How to Fix Them

• Issue: Muscle soreness and fatigue after running.
  Solution: Rest, stretching, and hydration; gradual increase in intensity.

• Issue: Shin splints or stress injuries.
  Solution: Check running form, footwear, and increase cross-training.

• Issue: Motivation loss.
  Solution: Join running groups, set achievable goals, track progress.

Expert Tips

• Pay attention to form, focusing on mid-foot strike and relaxed upper body.

• Include interval training for improved cardiovascular fitness and endurance.

• Prioritize recovery days to allow muscles and tissues to adapt.

• Hydrate adequately and maintain a balanced diet for energy and repair.
