In some cases, lifting heavy weights may cause chest pain and heart racing, or heart palpitations. Usually, an individual experiencing such symptoms has an underlying problem such as cardiopulmonary disease or hypertension. Using improper form or not breathing correctly during heavy weightlifting may also cause chest pain or heart palpitations. Consult your doctor before beginning any exercise program, and particularly if you experience these symptoms during weightlifting or any other exercise.
Valsalva Maneuver
The Valsalva maneuver is a respiratory maneuver, sometimes performed during heavy lifting exercises, which can cause chest pain and heart racing, the book "Physiology of Sport and Exercise" explains. It occurs when the individual closes the glottis --- the opening between the vocal cords --- and forcibly contracts the diaphragm and abdominal muscles. This dramatically increases blood pressure and restricts blood flow to the heart. If the Valsalva maneuver is held too long or the individual has an underlying problem, it could result in loss of consciousness or a stroke.
Hypertension
Hypertension, or high blood pressure, can also result in chest pain and heart palpitations. Individuals with hypertension during the resting state have a greater risk of developing complications such as chest pain and heart racing when lifting weights, Dr. Sheldon Sheps warns on the Mayo Clinic website. Although, regular, moderate lifting of lighter weights can help to lower blood pressure, it is important for hypertensive patients not to lift heavy weights.
Hyperventilation
A common cause of chest pain and heart palpitations is hyperventilation syndrome, according the Noninvasive Heart Center website. Hyperventilation is rapid breathing that is often a result of stress. Hyperventilation will usually occur after, rather than during, heavy lifting. Dizziness, light-headedness, chest pain and racing heart are common symptoms of hyperventilation, which results from over-breathing and blowing carbon dioxide out of the lungs.
Proper Breathing Techniques
When performing any type of heavy lifting, it is important to continue to breathe normally. Holding your breath or hyperventilating during lifts will result in elevated blood pressure, chest pain or racing heart rate. Lifting with your legs and not your back will also reduce the risk of symptoms developing. Additionally, if you have been diagnosed with cardiopulmonary disease or hypertension, you should avoid heavy lifting and get a doctor's approval before beginning any new exercise program.
