According to a scientific review, resistance training appears to be linked with a significantly lower risk of all-cause mortality, cardiovascular disease, cancer, diabetes, and lung cancer. The review, which was based on observational studies, found that strength training is associated with a 10-17% lower risk of these conditions. In addition, strength training has two key outcomes: muscle hypertrophy (increase in muscle size) and increased muscular strength. Both of these outcomes have been linked with a reduction in all-cause mortality.
One potential risk of resistance training is the possibility of injury. Injuries can occur due to improper form, excessive weight, or outdated or poorly maintained equipment. Therefore, it is important to always warm up before a resistance training session and to use proper form to minimize the risk of injury. Additionally, it is essential to seek medical attention if damage occurs, as failing to do so can increase the risk of long-term complications or even death.
Another potential risk of resistance training is the possibility of a cardiovascular event, such as a heart attack. Although the risk of a cardiovascular event occurring during resistance training is low, it is still important to consider any pre-existing conditions or risk factors before starting a resistance training program. Individuals with a history of cardiovascular disease or those at high risk for cardiovascular disease should consult with a healthcare professional before starting a resistance training program.
Another potential risk of resistance training is the possibility of overtraining. Overtraining can occur when an individual needs more resistance training with sufficient rest and recovery. Symptoms of overtraining include decreased performance, increased fatigue, and decreased muscle mass. Therefore, it is vital to allow adequate rest and recovery between resistance training sessions and to listen to the body's needs to prevent overtraining.
In conclusion, while resistance training has numerous health benefits, there are also potential risks associated with the activity. Therefore, taking precautions to minimize the risk of injury and considering any pre-existing conditions or risk factors before starting a resistance training program is vital. Additionally, it is essential to allow for adequate rest and recovery and to listen to the body's needs to prevent overtraining. By following these guidelines, individuals can safely engage in resistance training and reap its numerous benefits.
