Physical inactivity is a significant health concern that should be regarded as a disease. It poses a mortality risk comparable to smoking, cardiovascular disease, and type 2 diabetes.
In Australia, as individuals age, they experience notable muscle mass decline. By age 50, Australians lose approximately 10% of their peak muscle mass; by age 70, this loss increases to about 40%. This reduction isn't merely cosmetic; it's crucial for maintaining physical independence and overall survival.
Higher muscle mass is linked to a 30% reduction in all-cause mortality. Moreover, grip strength serves as a more reliable predictor of cardiovascular-related mortality—the leading cause of death in Australia—than high blood pressure, yet it often goes unrecognized.
Strength training is also associated with a 42% lower risk of dementia. Despite this, resistance training is frequently viewed as optional rather than essential. In reality, it's a fundamental aspect of healthy aging, enhancing muscle mass, strength, and bone mineral density.
Hip fractures are particularly concerning, as they can significantly impact mortality. In Australia, approximately 26% of individuals aged 45 and over who experience a hip fracture die within a year.
Engaging in resistance training can reduce the risk of such fractures by 30 to 40%, making these injuries largely preventable.
We possess the knowledge and data to address this issue. Incorporating resistance training, regular exercise, and proper nutrition are pivotal steps we can take to prevent disease and enhance health outcomes in Australia.
