St. Louis University
This pilot study will evaluate whether brief bouts of stair climbing performed throughout the day for two weeks can improve metabolic health, cardiovascular fitness, and other health-related outcomes in adults with overweight or obesity who do not regularly exercise. Participants will complete approximately 6-8 brief stair-climbing "exercise snacks" per day for 14 days, with each bout consisting of approximately 60 total stair steps performed at a challenging but safe self-selected pace. Participants will complete baseline and post-intervention assessments at Saint Louis University. These assessments will include continuous glucose monitoring and standardized meal testing to evaluate glucose responses, as well as measures of aerobic fitness, anaerobic power, body composition, waist circumference, and muscular strength. The study will also evaluate adherence, perceived exercise intensity, and the feasibility of incorporating brief stair-climbing bouts into daily life.
This is a pilot intervention study designed to examine the short-term effects and feasibility of frequent stair-climbing "exercise snacks" in adults with overweight or obesity. Exercise snacks are brief bouts of physical activity performed intermittently throughout the day and may provide a time-efficient approach to increasing physical activity. The study will enroll approximately 12 adults aged 18-35 years with a body mass index of 25.0-34.9 kg/m² who are otherwise healthy and do not regularly participate in structured exercise. Participants must have regular access to a safe staircase. Pa…
Inclusion Criteria: * Age 18-35 years and able to provide informed consent. * Body mass index (BMI) 25.0-34.99 kg/m² and otherwise healthy, without chronic disease. * Sedentary or low-active lifestyle, defined as no regular structured exercise ≥3 days/week for ≥30 minutes per session during the past 3 months. * Access to a safe staircase that permits completion of approximately 60 total stair steps per exercise bout. Approximately 60 upward steps are preferred when available; one or more flights may be used repeatedly if needed. * No contraindications or increased-risk findings identified on…
Participants will perform brief stair-climbing exercise snacks 6-8 times per day for 14 days. Each bout will consist of approximately 60 total stair steps completed at a self-selected challenging but safe pace. When possible, participants will complete approximately 60 upward steps. If 60 continuous upward steps are not available, participants may use one or more flights repeatedly by ascending and descending carefully until approximately 60 total steps are completed. The intervention will be completed independently in participants' usual daily environments, such as home, work, or campus. Participants will be instructed to use the handrail when needed, descend slowly and carefully, and not run down the stairs.
