You will learn about several aspects of your cardiovascular fitness, including:

• Lactate Threshold (LT2): The level above which pyruvate—an intermediate product of anaerobic metabolism—is produced faster than it can be used aerobically; unused pyruvate splits into lactate (lactic acid) and positively charged hydrogen ions; continued exercise above the lactate, or anaerobic, threshold results in accumulation of these ions—acidosis—causing exhaustion and intramuscular pain.
  ‍
• Training Zones: Training zones are calculated based on the relationship between your VO2 Max, heart rate, and mechanical output (power/pace). By completing VO2 Max testing, it allows for accurate prescription of these training zones, optimising training and performance.
  ‍
• Pulmonary Diffusion Capacity: One of the factors that determines VO2 Max, it describes the ability of the lungs to uptake large volumes of air ad exchange oxygen and carbon dioxide through the alveoli.
  ‍
• Cardiac Output: The ability of the heart to pump large volumes of oxygenated blood.
  ‍
• Oxygen Carrying Capacity of the Blood: The amount of oxygen that can be transported to the muscle, important for VO2 Max.
  ‍
• Skeletal Muscle Oxygen Extraction: Describes the muscle's ability to uptake and utilise oxygen for function.
  ‍
• Aerobic Threshold (LT1): The first lactate threshold, also known as LT1 or the aerobic threshold is used to demarcate zone 1 and 2. LT1 is defined as the lowest intensity at which there is a sustained increase in blood lactate concentration above resting values.
