TL;DR:

An hourly ~5min cycling exercise on a stationary bicycle trainer results in a 31% decrease of area under the curve (AUC)* of postprandial triglyceride levels in blood plasma and a 43% increase in whole body fat oxidation.

The cycling exercise consisted of five 4-sec all out sprints followed by 45-sec rests.

The exercise was performed once per hour during 8 hours of sitting and compared to 8 hours of pure sitting.
