PHYSICAL ACTIVITY AND STRENGTH TRAINING INCREASE LIFE EXPECTANCY
Regular physical activity, which includes exercise and strength training, is associated with increased life expectancy and better quality of life.
Benefits of Physical Activity
Reduction of chronic diseases: such as type 2 diabetes, heart disease, and certain types of cancer. A 2021 study found that physical inactivity is associated with an elevated risk of mortality from all causes (Gordon et al., 2021).
Improvement of mental health: Regular exercise has been linked to a reduction in symptoms of depression and anxiety. A 2022 review of studies confirms that regular physical activity can have significant antidepressant effects (Mikkelsen et al., 2022).
Weight control: Maintaining a healthy weight through physical activity reduces the risk of obesity-related diseases, which impact life expectancy (Wang et al., 2022).
Benefits of Strength Training
Preservation of muscle mass: Strength training is crucial for combating sarcopenia, the loss of muscle mass associated with aging. A 2021 study showed that older adults who engaged in strength training had greater muscle mass and functionality (Dela et al., 2021).
Improvement of bone density: Regular resistance exercises improve bone density, reducing the risk of fractures. A recent meta-analysis confirmed that strength training significantly increases bone density in older adults (López et al., 2022).
Cardiovascular benefits: Strength training also improves cardiovascular health. A 2020 study found that people who engage in strength training have a lower risk of heart disease and cardiovascular mortality (Oja et al., 2020).
Scientific Evidence on Life Expectancy
A meta-analysis by Arem et al. (2015) concluded that meeting physical activity recommendations is associated with a reduction in the risk of premature death. This study included over 600,000 adults and showed that regular physical activity has a positive impact on longevity.
A recent study by Gordon et al. (2021) analyzed data from over 100,000 participants, and those who engaged in moderate or intense physical activity had a significantly lower risk of mortality compared to sedentary individuals.
Another study by López et al. (2022) found that strength training is associated with a 23% reduction in overall mortality, highlighting its importance in life expectancy.
Conclusions
Physical activity, regular exercise, and strength training are essential for increasing life expectancy. They not only improve physical and mental health but also contribute to a longer and healthier life.
