How Running Benefits Your Lungs and Overall Health
Running is one of the best forms of exercise for improving cardiovascular health and lung function. However, many runners experience strange bodily changes that signal running's weird effects. Understanding running's impact on the lungs and body can help you leverage the benefits and mitigate the downsides.
Running Improves Lung Capacity and Function
As you run, your breathing and heart rate increase to circulate more oxygenated blood to your working muscles. Over time, your body adapts to meet this increased demand by expanding lung capacity and efficiency.
With deeper inhalations and stronger exhalations, more air moves in and out of your lungs. Your lung's air sacs can also extract more oxygen from each breath. These adaptations allow your cardiovascular system to transport ample oxygen to muscles during aerobic activity.
The Diaphragm and Intercostal Muscles Strengthen
The high ventilation demands of running require your primary breathing muscles, the diaphragm and intercostals between the ribs, to powerfully contract and relax.
Much like other muscles exercised during running, the diaphragm and intercostals adapt to the consistent overload. As they strengthen, your maximum breathing capacity increases to take in more air.
Respiratory Issues May Improve
The cardiovascular improvements from running can also decrease symptoms for those with lung conditions like asthma. However, asthma symptoms may initially worsen when beginning a running routine before adaptation occurs.
If you have respiratory issues, consult your doctor, use your inhaler as needed, and ease into running to allow your lungs to adjust without complication.
Running's Impact on Oxygen Transport and Usage
More Efficient Oxygen Transport
As your lungs grow more efficient, your blood also adapts to better transport oxygen. When running, your heart rate and stroke volume increase to circulate more oxygen-rich blood.
The number of red blood cells and hemoglobin levels may rise as well, allowing each cell to carry more oxygen to tissues. These combined effects significantly boost oxygen delivery during exercise.
More Mitochondria in Muscles
Oxygen supplied by the lungs and blood allows muscles to produce aerobic energy. Running triggers muscle cells to grow more mitochondria - the "powerhouses" that convert oxygen and fuel into ATP energy.
With greater mitochondrial density, your muscles squeeze more energy from each oxygen molecule to resist fatigue. The increased efficiency benefits cardiovascular fitness and endurance.
Oxygen Utilization Improves
While your muscles require ample oxygen when running, they also must efficiently use oxygen without wastage. The enzyme called cytochrome c oxidase facilitates over 95% oxygen utilization for energy production.
Running boosts levels of this enzyme so your muscles can effectively harness oxygen. Alongside more oxygen supply, better use optimizes your endurance.
How Running Impacts Lung Health and Disease Risk
Reduced Risk of Respiratory Infection
Engaging in regular moderate exercise like running may reduce susceptibility to lung infection. Temporary boosts to immune cells and antibodies during running protect lung airways.
Over time, these acute immune changes translate to fewer colds and bouts of pneumococcal pneumonia among active individuals.
Lower Lung Cancer Risk
According to research studies, consistently active runners have a lower chance of developing lung cancer. Reduced exposure to carcinogens and boosted immunity are likely mechanisms providing protection.
However, even active smokers retain a very high lung cancer risk. Quitting smoking remains vital for lung health regardless of running habits.
Decreased Inflammation
Lung diseases often involve inflammatory damage that impairs respiratory function. The anti-inflammatory effects of routine exercise like running can prevent and alleviate such issues.
For lung disease patients, running may enhance quality of life and slow disease progression through these inflammation-blunting mechanisms.
Strange Changes Running Causes to Your Lungs and Body
"Runner's Face" Collagen Breakdown
The weight and high impacts involved in running can damage collagen structures supporting facial tissues. The result is accelerated aging called runners face.
You may notice more wrinkles, sagging skin, and gauntness from the pounding effects of running. Using proper technique and allowing recovery time reduces collagen breakdown.
Coughing Up Black Substance
In rare instances, endurance runners cough up dark sputum after races or workouts. This ominous-looking substance called runners black lung comes from small capillaries bursting under intense respiratory stress.
The minor bleeding causes streaking in mucus. Unless it persists, black lung isnt harmful and resolves with rest. Proper training prevents lung capillaries from rupturing.
Dead Butt Syndrome
Running engages muscles in the hips, glutes, hamstrings and lower body neglected during usual daily motions. After years of heavy training, these running muscles remain perpetually tight and weaken from overuse.
Chronic tightness and wasted muscles lead to dead butt syndrome, making it difficult to sit or climb steps. Strengthening and stretching these muscle groups combats dead butt syndrome.
By highlighting running's many health boons alongside strange side effects, you can craft an exercise plan that maximizes benefits for your lungs and overall wellness.
