Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Rationale: Fractionalized physical activity is associated with reduced BMI, glycated hemoglobin, lower 2-hr plasma glucose and insulin sensitivity in cross-sectional studies. Yet, few studies have examined the effects of fractionalized or intermittent physical activity in a prospective manner. Furthermore, the research is limited to patients with diagnosed type 2 diabetes, or using exercise of a moderate intensity.
The hypothesis is that stair climbing, a vigorous-intensity activity, may have a greater health effect. However, this has not been tested in short bouts of activity that are spread out during a day.
Implications: Fractionalized physical activity may be more feasible for adults at risk for, or with diagnosed type 2 diabetes who are not currently active. These short bouts can increase energy expenditure throughout the day, rather than in one long continuous bout as currently recommended.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Stair Climbing 4x/day
Participants use the stair climber 4 times per day, for 4 minutes at a time. Total dose = 16 minutes.
Stair Climbing Frequency
Includes 1 sedentary day prior to completing crossover phases.
Stair Climbing 8x/day
Participants use the stair climber 8 times per day, for 2 minutes at a time. Total dose = 16 minutes.
Stair Climbing Frequency
Includes 1 sedentary day prior to completing crossover phases.
