Vaping, the inhaling and exhaling of vapor produced by an electronic cigarette or similar device, has gained widespread popularity recently. Initially marketed as a safer alternative to traditional tobacco smoking, vaping has become a controversial topic due to emerging health concerns.

People focus on how vaping affects breathing. There is also a growing interest in figuring out how it might influence other body parts, like muscles.

Understanding Vaping​

Vaping, also known as electronic cigarette (e-cigarette) use, involves inhaling and exhaling an aerosol produced by a battery-powered device. This aerosol typically contains nicotine, the addictive substance found in tobacco, along with flavorings, propylene glycol, vegetable glycerin, and other chemicals. Unlike traditional cigarettes, which burn tobacco to produce smoke, vaping devices heat an e-liquid or vaping juice.

While nicotine is an addictive substance found in tobacco, vaping allows users to control their nicotine intake by selecting e-liquids with varying nicotine concentrations, including options with no nicotine at all. This customization feature has contributed to the popularity of vaping as a potentially less harmful alternative to traditional smoking.

Vaping devices come in various shapes, sizes, and designs, catering to users' diverse preferences and needs. Vape pens are cylindrical devices resembling a pen or marker. Box mods are larger, box-shaped devices with more advanced features. They often include adjustable power settings, temperature control, and larger tanks for extended use.

Pod systems are compact, user-friendly devices with a disposable or refillable pod containing the e-liquid. They are famous for their convenience and ease of use, making them suitable for beginners.

The Science of Muscle Growth​

Protein synthesis is a central aspect of muscle growth. The body synthesizes new proteins to repair damaged muscle fibers and create additional contractile proteins, such as actin and myosin, to increase the size and strength of muscle cells. This process is regulated by various signaling pathways, with the mammalian target of rapamycin (mTOR) being a key player in stimulating protein synthesis.

Resistance training, such as weightlifting or bodyweight exercises, is the key stimulus for muscle growth. After a training session, the body goes into repair mode, mending the muscle fibers' microtrauma.


Vaping's Biological Impact on the Body​

‌Vaping doesn't just impact one specific system. It can have a ripple effect, influencing various bodily functions. Nicotine, a common component in e-liquids, can also contribute to blood vessel constriction, hindering blood flow.

It also weakens the immune system, making the body more susceptible to infections. This effect hinders the body’s ability to recover from injuries related to exercise.

The respiratory system bears the brunt of the potential consequences of vaping. Even without combustion, the chemicals present in e-liquids can irritate the airways, causing coughing, wheezing, and shortness of breath. It can also trigger lung inflammation, leading to long-term damage and hindering their ability to function optimally.

The Role of Nicotine and Other Substances​

Adequate blood flow is crucial for delivering oxygen and nutrients to muscles during exercise. ‌The potential blood flow restriction due to nicotine-induced vasoconstriction may hinder the optimal delivery of nutrients to muscle tissues, impacting muscle function and recovery.

Some flavorings and additives in vape products may have unknown effects on the body. Their inhalation could contribute to systemic changes that affect muscle growth.

Additionally, certain flavorings used in e-liquids, particularly diacetyl, have been linked to popcorn lung, a severe lung condition characterized by scarring of the airways. This condition can significantly impact respiratory health and indirectly hinder muscle growth due to reduced exercise capacity.


Vaping and Exercise Performance​

‌Vaping, mainly when containing irritants, can damage and inflame the lungs, hindering their ability to efficiently extract oxygen from the air. Damaged and inflamed airways can make breathing more complex, requiring your body to work harder to breathe oxygen. This increased effort translates to less energy available for actual exercise activities.

Its nicotine content can also elevate heart rate and blood pressure even at rest. The added stress on the cardiovascular system can further limit the ability to reach peak performance during exercise.

Aside from damaging the lungs and elevating heart rate, it may affect thermoregulation or the body's ability to regulate temperature during exercise. Changes in temperature regulation could impact workout performance.

The Role of Nutrition and Hydration​

‌The potential for respiratory and oral irritation may indirectly affect dietary habits and nutrient intake. Individuals experiencing discomfort or changes in taste perception due to vaping may alter their nutritional choices, potentially influencing nutrient absorption. For some, it changes the taste perception.


Chronic inflammation triggered by vaping can damage the lining of the digestive tract, hindering the proper absorption of nutrients.

Muscle tissue is approximately 75% water, making adequate hydration essential for optimal muscle function and growth. Nicotine has diuretic properties that can increase urine production. Vaping can also irritate the mouth and throat, leading to dryness and reduced saliva production.

Dehydration can lead to decreased strength and impaired muscle function. This effect makes it harder for muscles to perform optimally during workouts. It can lead to electrolyte imbalances, essential minerals in muscle function, and nerve transmission. This imbalance can further compromise muscle performance and recovery.

Vaping and its Impact on Recovery, Sleep, and Cardiovascular Health​

During sleep and rest, the body reduces inflammation at the injury site, creating an environment conducive to repair. The increased blood flow delivers essential nutrients and oxygen to facilitate the repair process.

Quality sleep is necessary for maintaining a balanced hormonal profile, including regulating cortisol and insulin sensitivity. Hormones released during sleep contribute to overall well-being and impact energy metabolism, vital for sustained physical performance.

‌Nicotine can disrupt sleep patterns, leading to fragmented sleep and inadequate rest. This sleep deprivation can significantly hinder energy levels and motivation to exercise, ultimately impacting performance and progress.

Vaping has also been linked to endothelial dysfunction, impairing the function of the inner lining of blood vessels. Endothelial dysfunction is a precursor to atherosclerosis, the buildup of plaque in arteries that can lead to cardiovascular diseases such as heart attacks and strokes.

Vaping's Effect on Protein Synthesis​

‌Nicotine's impact on cognitive function and mood may indirectly influence adherence to exercise routines and dietary habits. Consistency in training and nutrition is critical for promoting an environment conducive to protein synthesis.

Nicotine, as a stimulant, triggers the release of various hormones, including adrenaline and cortisol. Adrenaline can have a short-term positive impact on exercise performance. Chronically elevated cortisol levels may negatively affect protein synthesis by promoting muscle protein breakdown.

Myths and Facts about Vaping and Muscle Growth​

People switch to vaping, thinking it is harmless compared to smoking. In Respiratory Research from BioMed Central, vaping can cause inflammation and damage to lung tissue, potentially leading to respiratory illnesses. This inflammation can hinder lung function, impacting exercise performance and potentially hindering muscle growth.

Vaping doesn’t also affect lung health alone. A 2018 study published in "Nicotine & Tobacco Research" found that nicotine exposure from vaping can impair blood vessel function, potentially increasing the risk of cardiovascular diseases.

It is also not an effective way to quit smoking for athletes who want to improve muscle development. While quitting smoking is undoubtedly beneficial for overall health, switching to vaping is not a healthy alternative for athletes seeking to optimize their muscle development. The potential drawbacks of its nicotine content on protein synthesis, blood flow, and overall health outweigh any perceived benefits.

Long-Term Health Effects of Vaping​

‌Vaping can increase the risk of developing chronic obstructive pulmonary disease (COPD), a group of progressive lung diseases that obstruct airflow. While research on the long-term cancer risks of vaping is still ongoing, the presence of certain carcinogens and other harmful chemicals in e-liquids raises concerns about potential cancer risks associated with long-term vaping use.

Assess respiratory health regularly, paying attention to changes in lung function, breathing patterns, or symptoms such as coughing and shortness of breath.

Stay adequately hydrated, especially considering potential vaping-related dry mouth and respiratory irritation. Proper hydration supports overall well-being and aids in recovery after physical activity.

If applicable, consider smoking cessation programs or resources to help transition away from vaping. Quitting nicotine use can have positive effects on cardiovascular and respiratory health.
