Prolonged Sitting on Responses to Short-Term Exercise Training

September 29, 2021 updated by: Edward F. Coyle, University of Texas at Austin

Effect of Prolonged Sitting on Metabolic and Cardiovascular Responses to Short-Term Exercise Training

Prolonged sitting has been shown to effect the response to a high fat tolerance test (HFTT) after acute exercise. This study will evaluate the effect of prolonged sitting on response to a HFTT after a short term training period.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Sitting with Exercise
Subjects will complete a short term training protocol while sitting >11 hours per day. This training will be preceded by a VO2max test to aid in setting the correct intensity for training. Subjects will be asked to complete three high fat tolerance tests. One to establish a baseline, the second to determine the acute effects of training, and a third at the completion of training to determine the cumulative effect of exercise training.
Subjects will commit to sitting more than 11 hours per day and taking less than 5000 steps per day while participating in exercise training.
Active Comparator: Walking with exercise
Subjects will complete a short term training protocol while sitting <5 hours per day. This training will be preceded by a VO2max test to aid in setting the correct intensity for training. Subjects will be asked to complete three high fat tolerance tests. One to establish a baseline, the second to determine the acute effects of training, and a third at the completion of training to determine the cumulative effect of exercise training.
Subjects will commit to sitting less than 5 hours per day and taking more than 10000 steps per day while participating in exercise training.
