Your Organs When You Go For A Run

1. Heart Rate: Your heart rate increases significantly to deliver more oxygenated blood to your working muscles. This can reach up to 80-90% of your maximum heart rate during intense running.
2. Stroke Volume: The amount of blood pumped out of the heart with each beat increases to deliver more oxygen and nutrients to the muscles.
3. Blood Pressure: Blood pressure typically rises during running due to the increased workload on the heart and blood vessels.

Respiratory System:

1. Breathing Rate: Your breathing rate increases to take in more oxygen and expel excess carbon dioxide produced by the working muscles.
2. Tidal Volume: The volume of air you inhale and exhale with each breath increases to maximize oxygen intake.
3. Oxygen Utilization: Your muscles extract more oxygen from the blood to meet their energy demands during running.

Musculoskeletal System:

1. Muscle Contractions: Your muscles contract repeatedly to propel you forward, generating the force required for running.
2. Muscle Fiber Recruitment: Different muscle fiber types are recruited depending on the intensity and duration of the run. Fast-twitch fibers are used for sprints, while slow-twitch fibers are utilized for endurance runs.
3. Muscle Endurance: Regular running improves muscle endurance, allowing you to run for longer periods without fatigue.

Endocrine System:

1. Adrenaline and Noradrenaline: These hormones are released to increase energy production and prepare the body for strenuous activity.
2. Endorphins: These hormones are released to elevate mood and reduce pain perception, contributing to the “runner’s high” experience.
3. Growth Hormone: The release of growth hormone stimulates muscle growth and repair, aiding in post-run recovery.

These physiological changes demonstrate how the human body is remarkably adaptable to meet the demands of running. Regular running can significantly improve cardiovascular health, respiratory function, muscular strength and endurance, and overall well-being.
