Short (60 sec) post-meal sprints are better than longer sprints
Climbing stairs for 60-seconds, 1.5 hrs after a meal improves glucose clearance from the blood and reduces post meal blood glucose spikes.
Twenty healthy young males were asked to cycle at maximal effort for 60-seconds and 120-seconds, 90-minutes after eating a standard meal.
Blood glucose at 1.5 hrs was lower after 60-second sprint than 120-second sprint.
60-second and 120-second sprints both accelerate the post-prandial decrease in blood glucose in young healthy males, 60-second sprint being superior in producing this response, even though it is easier to perform and less time consuming.
