Investigating the effects of interrupting various lengths of prolonged sitting with bike sprints on post prandial lipemia the next day. We will conduct three trials, one control, one with two-hour sitting intervals (total of 4 bouts of bike sprints) and one with 6-hour sitting intervals I total of two bouts of bike sprints). A milkshake high fat tolerance test will be conducted the next day and whole body fat oxidation as well as triglyceride area under the curve will be measured every hour for the duration of the 6-hour test.

This is a behavioral intervention designed to determine the effect of breaking up prolonged bouts of sitting every 2 hours and every 6 hours with 5 sets of 4 second bouts of maximum effort bicycle ergometer accelerations compared to sitting alone on the blood triglyceride response and whole body fat oxidation after a high fat meal.

Triglyceride area under the curve
Blood measurements baseline and every hour during a high fat tolerance test.
Time frame: 6 hour long high fat tolerance test
Whole body fat oxidation
Expired gas collection and measurement of expired gas concentrations in mass spectrometer, baseline and every two hours during high fat tolerance test.
Time frame: 10 min, baseline, 2 hours post ingestion of shake, 4 hours, 6 hours.
