A rising physique of proof exhibits that quick bouts of motion, comparable to a minute or two of moderate- to higher-intensity motion, immediate your muscle tissue to make use of glucose (sugar) for power, which might help your physique deal with glucose. Over time, these mini exercise breaks would possibly assist enhance insulin (a hormone that helps regulate glucose) sensitivity and stop extended spikes in blood sugar that always occur after consuming.
Analysis exhibits train snacks might help scale back postmeal blood sugar spikes, making this strategy as efficient — in some instances simpler — for glucose management than conventional longer exercises, particularly when timed round meals.
It begins with the essential physiology of motion. When your muscle tissue contract, they want power. To fulfill this demand, your physique pulls glucose from the bloodstream into the muscle tissue, the place it’s used as gas, naturally reducing blood sugar ranges within the course of. The extra intense the motion, the extra glucose your muscle tissue use.
“Quick bouts of motion — or train snacks — assist speed up this course of,” says Andrew Koutnik, PhD, analysis college on the Florida State College Institute for Sports activities Science and Drugs in Tallahassee. “Over time, usually doing quick bouts of motion additionally improves insulin sensitivity, which implies your physique wants much less insulin to retailer the identical quantity of glucose. And these advantages apply to individuals with and with out diabetes.”
In different phrases, each brisk stroll, fast stair climb, or set of squats may give your physique a possibility to control blood sugar ranges, particularly when timing is intentional.
That’s as a result of after you eat, carbohydrates from meals are damaged down into glucose, which enters your bloodstream and raises blood sugar ranges. These ranges can stay elevated for as much as two hours.
However inserting transient motion breaks into that timeframe throughout the day might help handle these postmeal glucose spikes, stopping extended durations of elevated blood sugar.
That stated, train snacks aren’t solely useful after consuming. “Utilizing high-intensity train snacks earlier than a meal could make the muscle extra receptive to glucose. Then, low-intensity exercises after meals might help keep larger blood circulate and sugar supply to these muscle tissue. [This combination] might be simpler than both strategy used alone,” says James Cotter, PhD, an train physiologist and professor of bodily schooling on the College of Otago in Dunedin, New Zealand.
However the effectiveness of train snacks can depend upon components comparable to how onerous a specific muscle group is labored and the standard exercise depth, says Cotter, who was among the many first researchers to check train snacks for glucose management.
