In a new study, researchers found that just one minute of exercise per week is enough to provide health benefits to people over the age of 65.
The research was conducted by a team from Abertay University in Dundee.
As people age, they lose the ability to take glucose out of their blood which results in insulin resistance. This can lead to Type 2 diabetes and problems with the heart and liver.
The team examined groups of 65 to 75-year-olds participate in either once or twice weekly training sessions for a period of 8 weeks.
Each had been living a sedentary lifestyle and had not been taking part in regular exercise.
The participants took to stationary bikes and were asked to cycle as hard as they were able to for six seconds before resting for at least a minute.
They would repeat the process—which is known as sprint interval training (SIT) – until they had exercised for a total of one minute.
The team found that the once-weekly session was enough to produce improvements in blood glucose control and general mobility.
While those participating in the twice-weekly sessions observed a greater improvement, those taking part in the single session also observed change.
They also observed a difference in general function, greatly improving their ability to do everyday tasks such as getting up to answer a door and walk up and downstairs.
The team wants to see sprint interval training introduced to the government’s physical activity guidelines.
Currently, older adults are advised to participate in at least 150 minutes of moderate-intensity exercise each week, and that can be difficult to accrue.
The results provide further support for the inclusion of this form of training in the guidelines as one of the methods to gain health benefits.
