A recent meta-analysis study conducted by Grant Tomkinson, PhD, analyzed the results of 26 systematic reviews and 199 unique cohort studies to investigate the link between exercise, all-cause mortality, and cardiovascular health. The study involved more than 20 million researcher observations and found that increased physical activity through aerobic exercise can lower the risk of death from all causes, particularly heart disease. The researchers measured energy expenditure from cardio fitness with METs, where every additional 1-MET exerted via aerobic exercise was associated with a decrease in the risk of all-cause death by 11% to 17% and a reduction in the risk of heart failure by up to 18%.
Cardiorespiratory fitness, also known as cardio fitness or aerobic fitness, reflects the ability of the heart, lungs, and blood vessels to supply oxygen during physical activity. Aerobic exercise is crucial in maintaining cardiorespiratory fitness, which impacts overall health and longevity. Strong cardiovascular health is essential in preventing heart attacks, strokes, hypertension, and other cardiovascular diseases, which are leading causes of early death worldwide. Aerobic exercise can also help control cholesterol levels and improve the body’s response to stressors, contributing to overall health and well-being.
There are various ways to strengthen cardiorespiratory fitness through aerobic activities such as running, swimming, cycling, and dancing. Monitoring heart rate with fitness wearables and engaging in self-diagnostic questionnaires can help individuals assess their cardio fitness levels. Consulting with a healthcare provider or fitness professional is advisable, especially for those with pre-existing health conditions or beginners to exercise. Different individuals may respond differently to exercise, considering factors such as genetics, age, sex, overall health status, and lifestyle factors.
It is important to note that the benefits of aerobic exercise on cardiorespiratory fitness are not limited to reducing the risk of all-cause mortality and heart disease. Physical activity has been linked to a decreased risk of cancers, dementia, depression, kidney disease, and type 2 diabetes. While the exact mechanisms are not fully understood, maintaining strong cardiovascular health through exercise can have a positive impact on various aspects of health and well-being. Implementing a heart-health exercise regimen tailored to individual needs and capabilities can help individuals achieve optimal results and improve overall quality of life.
