Two March 2020 studies looked at the impact of physical activity on the health of older adults.
A study by Beaumont Health in Royal Oak, Michigan and Oakland University William Beaumont School of Medicine said,
"Finding a way to physically move more in an activity that suits your capabilities and is pleasurable is extremely important for all people, and especially for older people who may have risk factors for cardiovascular diseases. Physical activities such as brisk walking can help manage high blood pressure and high cholesterol, improve glucose control among many benefits."
Boston University researchers said,
"Promoting light-intensity physical activity and reducing sedentary time may be a more practical alternative among older adults,"
The study by the University of California, San Diego said,
"Despite popular beliefs, there is little evidence that people need to aim for 10,000 steps daily to get cardiovascular benefits from walking. Our study showed that getting just over 4,500 steps per day is strongly associated with reduced risk of dying from cardiovascular disease in older women."
"Taking more steps per day, even just a few more, is achievable, and step counts are an easy-to-understand way to measure how much we are moving. There are many inexpensive wearable devices to choose from. Our research shows that older women reduce their risk of heart disease by moving more in their daily life, including light activity and taking more steps. Being up and about, instead of sitting, is good for your heart."
