Not only does cigarette smoking harm the health of your heart and lungs, it also can become a major obstacle in the process of your body building and muscle growth. Here’s how smoking affects your muscle growth and strength.
Lowers physical endurance
The longer you can workouts the greater will be its impact on your muscle building process. But your ability to increase the intensity of your existing exercise routine will suffer as you smoke cigarettes.
Tobacco smoke contains tar – a thick, sticky, dark fluid produced when tobacco burns – and smoking causes tar accumulation in your lungs. Almost 70 percent of the tar in every cigarette smoked is accumulated in your lungs. This accumulated tar reduces the amount air you can breathe in.
Since you are not able to pull in enough air through your lungs during the workout, your muscles do not get enough supply of oxygen. This leads to early exhaustion and weakness in the body, which in turn reduces the number of repetitions you can perform and shortening the time you spend for developing muscle.
Decreases testosterone levels
Testosterone is a male hormone produced by the testicles. It is important to build and maintain bone and muscle mass. Smoking may damage the cells that produce testosterone within your body. This leaves you with lower than average testosterone levels. Lack of testosterone levels in your body will significantly hamper your muscle growth from workouts.
Increases heart rate
A smoker’s heart beats at an average 30 percent faster than that of a non-smoker. This in turn affects the outcome of any exercise that the smoker indulges in. Since a smoker’s heart is working harder to achieve adequate circulation, the individual uses more energy during his workouts.
This increase in heart rate diminish blood flow and reduce the smoker’s overall performance while performing the same exercise routine as a non-smoker.
