Strength Is Superior to Cardio

Strength training and steady-state aerobic activity are both essential for overall health and fitness, but strength training provides unique benefits that aerobic activity alone does not. Here are some reasons why strength training is superior to steady-state aerobic activity:

​

1. Myokines: Strength training stimulates the release of myokines, which are hormones produced by muscles during exercise. Myokines have a wide range of health benefits, including reducing inflammation, improving insulin sensitivity, and enhancing brain function. In contrast, steady-state aerobic activity does not produce as many myokines as strength training.
2. Bone Density: Strength training is particularly beneficial for building and maintaining bone density. As we age, our bones become weaker and more brittle, increasing the risk of fractures and osteoporosis. However, regular strength training can help to increase bone density and reduce the risk of these conditions. In contrast, steady-state aerobic activity has little to no impact on bone density.
3. Cognitive Decline: Strength training has also been shown to reduce the risk of cognitive decline, including dementia and Alzheimer's disease. A study published in JAMA found that older adults who participated in strength training had better cognitive function than those who did not. In contrast, steady-state aerobic activity may not provide as much protection against cognitive decline.
4. Physical Capability: Strength training is essential for maintaining overall physical capability over time. As we age, our muscles naturally begin to atrophy, leading to a loss of strength and mobility. However, regular strength training can help to maintain muscle mass and strength, allowing us to remain active and independent as we age. In contrast, steady-state aerobic activity may not provide the same level of protection against muscle loss and functional decline.

In summary, while both strength training and steady-state aerobic activity are important for overall health and fitness, strength training provides unique benefits that aerobic activity alone does not. By stimulating the release of myokines, increasing bone density, reducing the risk of cognitive decline, and maintaining physical capability over time, strength training is a critical component of any comprehensive fitness program.
