    How does Activity AI work?

    Activity AI works by integrating with your Garmin or Wahoo account to automatically import all your training sessions onto our platform. But that's just the start. The real magic happens with our Powertest AI, a sophisticated AI trained on over 10,000 Powertests using Tensorflow, predicting VO2max and Vlamax with 90 percent accuracy.

    Key metrics for the Powertest AI include power or speed during running (from which we derive the power) and heart rate. We've also investigated additional parameters such as cadence, temperature, and air pressure. Importantly, the user's maximum heart rate, body weight, and body fat are taken into account - all of which can be set by the user or obtained via API.

    Once you've completed a Powertest in the sports you wish to analyze, the Powertest AI forms the basis for calculating the carbohydrates, fats, and proteins you've consumed. The AI is constantly retrained, continuously learning and improving over time.

    Beyond the AI analysis, we also provide an evaluation according to Mader's method using test data. All other evaluations of the units are performed using classical statistics, ensuring you have a comprehensive understanding of your training performance.

    Erklärungen

    • Average Cda (aeroPoints - aP):

      Most of the energy you burn while moving is actually spent fighting against air resistance. That's where the average aerodynamic drag coefficient (Cda) in aeroPoints (aP, measured in dm²) comes in. Think of it like this: measuring Cda in dm² instead of m² is like counting calories in smaller, more digestible chunks. It’s all about keeping the scale practical – because dealing with tiny numbers like 0.001 m² is like trying to appreciate a chocolate bar one crumb at a time!

    • Average Crr (rollingPoints - rP):

      The average rolling resistance coefficient (Crr) in rollingPoints (rP) measures the resistance caused by the rolling motion of wheels on a surface. This value is crucial for assessing efficiency and energy consumption in movement.

    • 4 min Best Cda (aeroPoints - aP):

      The best aerodynamic drag coefficient (Cda) in aeroPoints (aP), measured over a 4-minute period. This value indicates the optimal aerodynamic efficiency achieved by an athlete or object during this time frame.

    • 12 min Best Cda (aeroPoints - aP):

      The best aerodynamic drag coefficient (Cda) in aeroPoints (aP), measured over a 12-minute period. This value provides insight into the maximum aerodynamic performance within this longer time span.

    • Effective Wind Speed (m/s):

      The effective wind speed, measured in meters per second (m/s), describes the wind conditions directly affecting an athlete. This value is important for assessing external conditions and their impact on performance.

    • Wind Speed and Direction:

      The wind conditions, including speed and direction, are crucial for understanding external factors affecting an athlete's performance. Effective wind speed, measured in meters per second (m/s), along with wind direction, help assess the impact of wind on your activity. These metrics provide valuable insights for optimizing your training and performance strategies.

    • Average Heart Rate:

      The average heart rate, measured in beats per minute (bpm), indicates the mean cardiac activity level during a specific period or activity. This metric is essential for understanding overall cardiovascular exertion.

    • Maximum Heart Rate:

      The maximum heart rate, recorded in beats per minute (bpm), represents the highest level of cardiac activity achieved during intense or peak exertion. It is a key indicator of an athlete’s cardiovascular capacity.

    • Heart Rate Efficiency (De Smet's Method):

      Heart Rate Efficiency, calculated as 1/slope according to De Smet's method and measured in Watts per beat per minute (W/bpm), evaluates the energy output in relation to heart rate increase. A higher value indicates greater cardiovascular efficiency, suggesting that more power can be generated with a smaller increase in heart rate. For example, a value of 3 W/bpm implies that an increase of 10 bpm could potentially produce an additional 30 Watts of power.

    • Heart Rate Drift per MJ of Mechanical Power:

      Heart Rate Drift, measured in bpm per Megajoule (MJ) of mechanical power, quantifies the increase in heart rate relative to the energy expenditure. This metric helps in understanding the cardiovascular response to sustained physical effort.

    • VO2max:

      VO2max, measured in milliliters of oxygen used in one minute per kilogram of body weight (vop = ml/min/kg), represents the maximum amount of oxygen an individual can utilize during intense exercise. It is a key indicator of aerobic endurance and cardiovascular fitness.

    • Vlamax:

      Vlamax, the maximal lactate production rate, is a key anaerobic capacity indicator, measured in (vlp = mmol/l/min). For Sprinters, a higher Vlamax indicates strong anaerobic power, essential for short, intense efforts. Allrounders show a balanced Vlamax, suitable for varied performance demands. In contrast, Long-Distance Runners typically have a lower Vlamax, prioritizing aerobic endurance and efficient energy use over longer durations.

    • Critical Power:

      Critical Power represents the threshold at which the type of muscle energy production shifts. It is the highest power output that can be sustained for an indefinite period without fatigue. Measured in Watts (W), it is a crucial metric for endurance performance.

    • FATmax:

      FATmax refers to the exercise intensity at which fat oxidation rates are maximized. It is measured as a percentage of VO2max and indicates the level of exertion where the body burns the highest proportion of fat as fuel, which is vital for endurance training and weight management.

    • Training Score:

      The Training Score is calculated based on the Mader Protein Synthesis Model, determining the maximum energy that can be expended weekly, relative to an athlete's VO2max and Vlamax. It's fine-tuned by training zones, aiming for an ideal 100 Percent weekly achievement. Exceeding this target? No problem! The excess percentage carries over to the next week. This method, having sculpted champions like Andreas Seewald and Henrique Avancini, optimizes adaptation while preventing overtraining. Training zones are split into three categories: Low (Regeneration, Base, Fatmax), Mid (Tempo, SweetSpot, Maximum Lactate Steady State, Threshold Power), and High (VO2max at 90 Percent and VO2max at 100 Percent).

    • Burned Carbohydrates:

      Burned Carbohydrates represent the calculated maximum carbohydrate depletion allowed per week, a crucial metric to prevent overtraining. It serves as a guide to ensure athletes consume enough carbohydrates during training, balancing energy expenditure with intake. By keeping tabs on carb depletion, athletes can maintain optimal performance levels without hitting the dreaded wall of energy depletion, making every spoonful of pasta count towards their training goals.

    • Recovery (RE):

      Recovery zone focuses on low-intensity training for active recovery. Ideal post-hard workouts or races, it aids muscle recovery while maintaining fitness, crucial for sustaining long-term training plans.

    • Base (BA):

      Base training, with moderate intensity, builds aerobic fitness foundations. It's vital for volume training, adapting to individual metabolic profiles. Tailored by our powertest, it ensures optimal adaptation and efficiency.

    • FATmax (FM):

      FATmax, where fat oxidation peaks, is crucial for endurance. It aids quicker recovery post high-intensity efforts and is key for efficient energy utilization. Enhancing FATmax involves targeted training, balancing VO2max improvement and VLamax reduction.

    • Tempo (GA2):

      Tempo training maintains challenging yet manageable intensity. It enhances muscular endurance and lactate threshold, serving as a bridge to higher training zones and improving overall stamina.

    • Sweet Spot (SS):

      Sweet Spot training, balancing high aerobic and anaerobic zones, offers significant gains with lower fatigue. It's versatile for various goals, from VLamax reduction to race-specific adaptations.

    • Maximum Lactate Steady State (ML):

      Maximum Lactate Steady State, a crucial endurance sport variable, balances lactate production and removal. Training here hones high-intensity endurance and is pivotal for race-specific preparations.

    • Threshold Power (TP):

      Threshold training, at the upper limit of sustainable power, boosts maximum aerobic performance. It's key for improving intense, sustained efforts, essential for competitive scenarios.

    • VO2max (V90):

      VO2max at 90% enhances aerobic capacity and efficiency. Tailored to individual kinetics, it forms a critical part of training, influencing VO2max improvement strategies.

    • VO2max (V100):

      VO2max training, the pinnacle of aerobic effort, drives significant gains in cardiovascular fitness. Its adaptation, influenced by individual profiles, is crucial for peak performance development.

    • Sprint (SP):

      Sprint training, performed above VO2max, targets explosive power and peak performance. It boosts neuromuscular coordination and anaerobic capacity, essential for short, intense efforts that demand maximum output.

    • Greyzone (GR):

      Greyzone training, situated between Threshold Power and VO2max at 90 percent, combines the benefits of both. Known as overunder training, it enhances lactate clearance and tolerance, bridging high-intensity and endurance efforts.

    • No Powertest AI:

      In your test, an evaluation with the Powertest AI was not possible. This is often due to an incorrect heart rate measurement. For highly accurate AI predictions, we need a heart rate belt that has a very good measurement quality, then it should also work very well with the Powertest AI.

    • Required Heart Rate Belt for Powertest AI:

      To utilize the Powertest AI, a high-quality chest heart rate belt is essential. The Powertest AI relies on accurate heart rate data to provide precise analyses and predictions.
