Pilot Stair Climbing Study

Jennifer Gay10 enrolled

Overview

This pilot study seeks to demonstrate feasibility to conduct data collection and illustrate potential for effect of fractionalized bouts of stair climbing on glucose control in adults at risk for type 2 diabetes.

Objective: Compare the short-term effects of two different fractionalized stair climbing bout protocols on glucose control among adults at risk for type 2 diabetes. 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.

Outcomes

Primary Outcomes

Continuous Glucose Monitor

Participant has device inserted prior to dinner the night before the sedentary day, completes the sedentary day and two stair climbing days, then has the device removed on the morning of the 5th day.

Time frame: Up to 5 days

Secondary Outcomes

Heart Rate

Measuring heart rate during stair climbing for % max heart rate and % heart rate reserve. Heart rate will be measured during the stair climbing bouts on each of the two intervention days.

Time frame: 2 Intervention Days
