1. At what workload/HR does the subject reach VT? LT? Definitions: Anaerobic Glycolysis - Metabolic pathway used to provide energy quickly that does not require oxygen Lactate threshold (LT) - Inflection point during exercise when the blood lactate concentration increases exponentially. Point during exercise at which the rate of lactate production exceeds the rate of lactate removal Metabolic acidosis - State of lowered pH resulting from acids produced in metabolism Tidal volume-Volume of air inhaled or exhaled in a single breath Ventilatory threshold - Inflection point at which pulmonary ventilation and carbon dioxide output begin to increase exponentially.

Does the LT occur at the same workload as the VT? Why or why not
