Aerobic Exercise

Overview

What is it?

Aerobic exercise is a form of physical activity that increases heart rate and oxygen consumption, involving activities like brisk walking, running, cycling, or swimming. It is naturally occurring and can be easily incorporated into daily routines. Aerobic exercise is primarily aimed at improving cardiovascular health, endurance, and overall physical fitness.

How does it work?

Aerobic exercise works by enhancing cardiovascular efficiency, increasing oxygen delivery to muscles, and improving endurance. It also promotes neurogenesis (the growth of new brain cells), increases levels of brain-derived neurotrophic factor (BDNF), and improves cerebrovascular function. These mechanisms collectively contribute to better physical and cognitive health, which are essential for longevity.

What are the benefits?

Aerobic exercise offers numerous benefits for longevity, including improved cardiovascular health, reduced risk of chronic diseases (e.g., heart disease, stroke, type 2 diabetes), enhanced cognitive function, and better balance and physical function in older adults. It also helps reverse age-related muscle loss, improves memory, and reduces the risk of falls, all of which contribute to a longer, healthier life.

Effectiveness

7.0

What does the research say?

Research shows that aerobic exercise can significantly improve longevity. For example, studies indicate that it reduces the risk of falls by 30% to 50% and improves balance by 16% to 42% in older adults . Additionally, 1 year of aerobic exercise can increase hippocampal volume by 2%, effectively reversing age-related brain volume loss by 1 to 2 years and improving memory . Aerobic exercise also improves cerebrovascular function, reduces arterial stiffness, and enhances endothelial function, which are critical for maintaining cognitive health and reducing the risk of dementia .

Side Effects

Minimal

None explicitly mentioned in the research

The reviewed papers do not explicitly mention any significant side effects of aerobic exercise when performed correctly and within individual limits .

Potential for overexertion or injury if not done properly

While not directly cited in the papers, overexertion or improper form during aerobic exercise could lead to injuries such as muscle strains or joint pain. It is important to start slowly and consult a healthcare provider if necessary.
