Design outcomes

Primary

Measure	Time frame
The primary outcome measures are: Cardiorespiratory data (Oxygen uptake (VO2), carbon dioxide output (VCO2), and Respiratory Exchange Ratio (RER). These data will be monitored using an Oxycon (portable metabolic system) to assess the proportion of fat and carbohydrate metabolism; Power Output (Pedal wattage would be measured to determine the physical effort exerted by the cyclist); Heart Rate and Perceived Effort (Borg scale for rating of perceived exertion); Energy Expenditure: The overall energy consumption will be calculated based on these measurements.	—
