NCT04241081

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Triglyceride area under the curve

    Blood measurements baseline and every hour during a high fat tolerance test.

    6 hour long high fat tolerance test

Secondary Outcomes (1)

  • Whole body fat oxidation

    10 min, baseline, 2 hours post ingestion of shake, 4 hours, 6 hours.

Study Arms (3)

Control group-no exercise

NO INTERVENTION

A no-exercise control. Must maintain \<4,500 steps per day for 3 consecutive days followed by a high fat tolerance test on day 4.

Exercise intervention 1

EXPERIMENTAL

Two consecutive days of \<4,500 steps per day followed by an intervention day on day 3. Intervention day consists of interrupting 8-hour sit with bike sprint protocol every 2 hours. Participants must aim to maintain \<2,500 steps on intervention day. A high fat tolerance test will be performed the following day on day 4.

Behavioral: Interrupting Prolonged Sitting with Periodic Interval Exercise: Effect on Postprandial Lipemia

Exercise intervention 2

EXPERIMENTAL

Two consecutive days of \<4,500 steps per day followed by an intervention day. Intervention day consists of interrupting 8-hour sit with bike sprint protocol every 6 hours. Participants must aim to maintain \<2,500 steps on intervention day. A high fat tolerance test will be performed the following day on day 4.

Behavioral: Interrupting Prolonged Sitting with Periodic Interval Exercise: Effect on Postprandial Lipemia

Interventions

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.
