An Examination Of The Validity Of An Ios-Based Heart Rate And Pulse Oximetry App During And After Moderate Intensity Exercise, Nathan Grizenko, Rachel Shipman, Ian Cree, Mitchell Colvin

ONU Student Research Colloquium

Fitness tracking apps are popular. There is little data validating their use during and after exercise. PURPOSE: Validate an iOS-based pulse oximeter against a fingertip pulse oximeter and a Polar® heart rate monitor during moderate intensity exercise and recovery. METHODS: Age Estimated Maximal Heart Rate (AEMHR) was calculated for fifteen college-aged students. Participants completed a 30-minute running trial divided into three 10-minute segments intended to elicit heart rate responses of 60, 70, and 80% of AEMHR. Heart rate and oxygen saturation data were collected at five and nine minutes of each segment. RESULTS: At 60% the digiDoc® app exhibited a …

Efficacy Of A Motivational Video On Heart Rate, Rpe, And Total Work Performed During Stationary Cycling, Hannah Angelella

Virginias Collegiate Honors Council Conference

Lack of enjoyment and motivation are factors that deter people from exercising. However, visual stimulation may help motivate or distract from exertion (1–3). The purpose of this study was to compare the effects of watching a motivational video (MV) versus a calming video (PV) while cycling. Ten recreationally-active subjects from the University of Lynchburg population completed two randomized, twenty-minute moderate intensity sessions on a stationary bike at least 48 hours apart. Subjects watched Bob Ross painting (PV) in one session and the Tour de France (MV) in another. The motivational video significantly improved mileage completed (8.01 vs 6.95 m, p …

A Comparison Of High-Intensity Interval Running And Tabata On Post-Exercise Metabolism: A Pilot Analysis, Lauren Pate

Undergraduate Research Conference

Introduction

• It is well established that energy expenditure following exercise (EPOC) remains elevated above resting values for a period of time (3).

• The magnitude and duration of this elevation may be primarily dependent on exercise intensity, with exercise duration and expenditure having a smaller influence (3, 6).

• Short durations (≤ 30 minutes) of high-intensity interval exercise (HIIE) is becoming a popular alternative for individuals who have limited time to exercise (5).

• When compared to rest, short-duration HIIE has been reported to elicit similar elevations in EPOC when compared to longer bouts of moderate-intensity continuous exercise (MICE) …
