Abstract

The American College of Sports Medicine (ACSM) recommends adults participate in weekly aerobic activity: minimum of 30 minutes moderate intensity exercise 5 days per week or 20 minutes of vigorous activity 3 days per week. The electrically assisted bicycle may help individuals achieve the ACSM’s aerobic recommendations and introduce inactive individuals to physical activity. However, individuals with differing fitness levels may require different considerations in order to meet ACSM recommendations. PURPOSE: The purpose of this study is to compare the physiological and mechanical differences of inactive and active individuals using a standard bicycle versus an electric bicycle. METHODS: Participants (N=24) will take part in 3 trials. They will be separated into two groups based on whether they meet ACSM aerobic fitness recommendations or not: Active Group (n=12) and Inactive Group (n=12). During the first visit participants will perform a VO2 max test. During the second visit participants will perform two randomized 2 mile cycling trials using 1) a standard bicycle and 2) an electrically assisted bicycle. The third visit will be performed indoors using a crank based power meter and computrainer ergometer to measure the relative power generated by the motor compared to the cyclist. VO2 and power output will be measured during all cycling trials. CONCLUSIONS: This research will allow us to make recommendations for utilizing the electrically assisted bicycle to achieve ACSM aerobic fitness guidelines.
