Technology In Sport Practice Exam

Data from a metabolic cart quantify metabolic rate and fuel use during exercise by measuring oxygen consumed and carbon dioxide produced. This lets you calculate real-time energy expenditure and determine which fuel—carbs or fats—the body is using, via the respiratory exchange ratio. From these measures you can estimate an athlete’s energy requirements for training and daily activity and assess aerobic endurance, often through metrics like VO2 max. That combination—how much energy is being spent and how efficiently the body uses fuel during sustained effort—is exactly what you need to tailor endurance training and nutrition. The other options aren’t what the metabolic cart provides. Heart rate and blood pressure are tracked with separate devices, not gas-exchange measurements. GPS-based distance is unrelated to metabolic gas data. Predicting injury risk from lactate thresholds involves different testing (often blood lactate measurements) and risk assessment beyond the gas-exchange data the metabolic cart supplies.
