Sigma Nutrition Radio
Cardiovascular Fitness: A Key to Health
Cardiovascular fitness, defined as the capacity of the heart, lungs, and circulatory system to support energy production during exercise, plays a crucial role in health. It enhances oxygen delivery to muscles and the removal of waste, fostering better muscular performance. Testing methods such as VO2 max and functional testing (like walking or running tests) accurately assess cardiovascular fitness. Research shows that fitness levels significantly predict the risk of adverse health events, particularly cardiovascular diseases, which are the leading cause of death globally. Notably, cardiovascular fitness is highly trainable, as opposed to some other fitness markers. While VO2 max tends to decline with age, this decline is often attributed to disuse rather than intrinsic changes in the body, highlighting the importance of ongoing exercise to maintain cardiovascular health.
