BodyStats’ VO2 Master Report
At BodyStats, our mission is to provide detailed, accurate, and actionable insights into your fitness and health. The VO2 Master Report offers a comprehensive analysis of your VO2 max, a crucial metric for understanding your cardiovascular and respiratory performance, helping athletes and fitness enthusiasts optimize their training and improve their performance.
Page 1: Overview
Maximal Metrics:
- Power: The highest power output achieved during the test, measured in watts. It reflects the maximum effort your muscles can sustain during intense exercise.
- VO2max: The maximum volume of oxygen consumed per kilogram of body weight per minute. This is a key measure of aerobic fitness and endurance, showing how efficiently your body can use oxygen during intense exercise.
- Heart Rate: The peak heart rate recorded during the test, measured in beats per minute (bpm). This metric helps assess your cardiovascular system’s response to maximum effort.
- Ventilation: The maximum rate of air inhaled and exhaled per minute, indicating respiratory system efficiency during high-intensity activity.
- Tidal Volume: The volume of air moved into or out of the lungs with each breath during normal breathing at maximum effort. This provides insights into lung capacity and respiratory efficiency.
- Respiratory Frequency: The number of breaths taken per minute at peak exercise intensity, reflecting the respiratory rate and how your respiratory system adapts to strenuous activity.
Ventilatory Threshold 1 (VT1)
Definition:
- VT1 is the point during increasing exercise intensity at which ventilation starts to increase at a faster rate than VO2 (oxygen consumption). This marks the shift from moderate to more intense exercise.
Determination:
- Gas Exchange: As exercise intensity increases, the body initially relies on aerobic metabolism, using oxygen to produce energy. At VT1, the body’s need for oxygen starts to outpace its supply, causing a noticeable increase in breathing rate to meet the demand for oxygen.
- Respiratory Markers: An increase in the ratio of ventilation (Ve) to oxygen consumption (VO2), and an increase in the fraction of expired oxygen (FeO2) without a corresponding increase in carbon dioxide production (VCO2).
- Heart Rate and Power Output: VT1 is typically identified by a breakpoint in the relationship between heart rate and power output, where the heart rate starts to increase more rapidly for a given increase in power.
Ventilatory Threshold 2 (VT2)
Definition:
- VT2 is the point at which lactate starts to accumulate in the blood. This indicates the onset of anaerobic metabolism, where the body cannot supply enough oxygen to meet the demands of the muscles, leading to increased production of lactate.
Determination:
- Lactate Accumulation: As exercise intensity increases beyond VT1, the body relies more on anaerobic metabolism, leading to lactate accumulation. VT2 is marked by a significant rise in blood lactate levels, indicating a shift to predominantly anaerobic energy production.
- Ventilation and Gas Exchange: A sharp increase in ventilation relative to both oxygen consumption (VO2) and carbon dioxide production (VCO2). The ratio of Ve to VCO2 reaches a peak and then starts to decrease, while the ratio of Ve to VO2 continues to rise.
- Heart Rate and Power Output: Similar to VT1, VT2 is identified by another breakpoint in the relationship between heart rate and power output, where the heart rate again increases disproportionately for a given increase in power.
Training Zones:
- Zone 1 (Warm-Up): A low-intensity zone designed for warming up the body before more intense exercise, preparing the muscles and cardiovascular system.
- Zone 2 (Fat Burning): Focuses on burning fat as a primary fuel source. This moderate-intensity zone is efficient for fat metabolism.
- Zone 3 (Endurance): A higher intensity zone aimed at improving aerobic capacity and endurance, involving sustained efforts to enhance cardiovascular and muscular endurance.
- Zone 4 (Vigorous): Involves high-intensity efforts that push your body’s limits, increasing both aerobic and anaerobic capacity. Often used for interval training.
- Zone 5 (Maximal): The highest intensity zone representing maximum effort, used to develop peak performance and is typically unsustainable for long durations.
How Your VO2max Compares to Others:
- A visual representation comparing your VO2max to statistical norms, helping you understand your relative fitness level and track changes over time.
Training Zones Calculation:
- Training zones are calculated using ventilatory thresholds to accurately determine your optimal training intensities based on your unique physiology. If thresholds cannot be found, zones are calculated based on the relationship between VO2, heart rate, and power or speed.
By understanding these metrics, you can tailor your training to improve your fitness and achieve your health goals. At BodyStats, we are committed to helping you make informed decisions for your health and wellness journey.

Why These Graphs Are Important: Telling a Story
Imagine you’re an athlete gearing up for your next big competition. You know that every second counts, and you need to maximize your performance. Here’s how the data from these graphs can be transformative for you:
Setting the Stage: The Warm-Up Phase
The journey begins with the warm-up phase. This initial period is crucial for preparing your body for the demands ahead. As you start, your heart rate and VO2 gradually rise, setting the stage for what’s to come. Monitoring these initial metrics ensures your body is ready, reducing the risk of injury and optimizing your performance.
Building Intensity: The Test Phase
As the test phase kicks in, the intensity ramps up. Your heart rate and VO2 start climbing steadily. The grey bars representing target power output show the increasing demands placed on your body. Here, you’re pushing your limits, and your body responds dynamically.
Ventilatory Threshold 1 (VT1): You reach VT1, where your breathing rate increases more rapidly than your oxygen consumption. This threshold is critical—it marks the point where your body transitions from moderate to more intense exercise. Understanding VT1 helps in structuring your training to build endurance, ensuring you can sustain higher intensities for longer periods.
Ventilatory Threshold 2 (VT2): As the intensity continues to climb, you hit VT2, where lactate starts accumulating in your blood. This is the boundary of your sustainable aerobic exercise. Knowing VT2 is invaluable for athletes like you, as it represents the upper limit of your aerobic capacity. Training just below this threshold can significantly boost your endurance and performance.
Breathing Efficiency: Ventilation and Respiratory Frequency
The lower graph tells the story of your respiratory efficiency. As you progress through the warm-up and test phases, your ventilation and respiratory frequency metrics show how efficiently you’re breathing.
Ventilation: Seeing how your ventilation rate changes with intensity helps you understand your lung capacity and efficiency. Efficient ventilation means your body is effectively supplying oxygen to your muscles, crucial for maintaining performance during long events.
Tidal Volume and Respiratory Frequency: These metrics highlight how deeply and frequently you’re breathing. During high-intensity efforts, optimal breathing techniques can make a huge difference. Training to improve these metrics can lead to better oxygen delivery and carbon dioxide expulsion, enhancing your overall performance.
