A professional athlete’s metabolic profile changes with adaptation to a training regimen with most of the training in the MFZ and a lower frequency of high-intensity (above the AT) training. Changes from TEST 1(dashed lines) to TEST 2 (solid lines) represent an increase in fat metabolism with decrease in carbohydrate burn, note the 20watt increase at the anaerobic threshold (AT) and lower carb requirement at higher power. https://www.enduranceptc.com/eptc-review/anaerobic-threshold-a-blurred-line monthly 0.5 2023-10-03 https://images.squarespace-cdn.com/content/v1/616b8a75a7a23650b7b72888/c1ae6908-3714-4421-983e-6926e99e368d/Screenshot+2023-09-14+at+6.12.37+PM.png EPTC REVIEW - Anaerobic Threshold: A Blurred Line - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/616b8a75a7a23650b7b72888/172ec33f-c46b-46d0-b2aa-b35b1337d881/image.png EPTC REVIEW - Anaerobic Threshold: A Blurred Line - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.enduranceptc.com/eptc-review/origins-of-power monthly 0.5 2024-04-04 https://images.squarespace-cdn.com/content/v1/616b8a75a7a23650b7b72888/df8fdb47-951e-40f3-97c3-7150796d4065/image5.jpg EPTC REVIEW - Origins of Power: How power is composed and why this matters - Make it stand out Example of how the intensity at 120% FTP has a totally different impact on 2 cyclists. In this example, it becomes clear that these athletes will have a different training stimulus on the aerobic energy system when they both ride at the same percentage of FTP. https://images.squarespace-cdn.com/content/v1/616b8a75a7a23650b7b72888/dfab6484-dea9-40a8-a34e-b97452aef0df/image6.png EPTC REVIEW - Origins of Power: How power is composed and why this matters - Make it stand out Real World example of the same effort before and after a training block: the maximum power production for 4min didn't change. However, the composition of the power differs significantly. On the far right: projection of the total maximum power if the known best training states of each power supply system would be combined by specific training. https://images.squarespace-cdn.com/content/v1/616b8a75a7a23650b7b72888/44031a5e-7e4c-43be-a4c0-5e9a99ad2ece/image1.png EPTC REVIEW - Origins of Power: How power is composed and why this matters - Make it stand out Example: Aerobic vs Anaerobic energy contribution in steady state conditions, depending on the power. https://images.squarespace-cdn.com/content/v1/616b8a75a7a23650b7b72888/d99f5ad9-3992-4631-a5c6-1bd78ca2aef5/image2.png EPTC REVIEW - Origins of Power: How power is composed and why this matters - Make it stand out Example: Lactate production and lactate combustion in steady state conditions, depending on the power and the energy system contribution. The energy contribution of your power number also impacts the fuel necessary to maintain that power. Our Performance Assessment using INSCYD, shows exactly which fuel contributes to your power: https://images.squarespace-cdn.com/content/v1/616b8a75a7a23650b7b72888/143451bd-0afc-4724-bd86-4127b20732e5/image3.png EPTC REVIEW - Origins of Power: How power is composed and why this matters - Make it stand out Example: Fat and Carbohydrate contribution in steady state conditions, depending on the power and the energy system contribution. As a result, you know how to fuel during training and racing. You will also find out that some athletes need to fuel differently, for the same amount of power. https://images.squarespace-cdn.com/content/v1/616b8a75a7a23650b7b72888/aa71df29-c571-42f3-b087-13223edd4f7e/image4.png EPTC REVIEW - Origins of Power: How power is composed and why this matters - Make it stand out Example of the maximal power produced by the glycolytic energy system (VLamax, red) and the aerobic energy system (VO2max, blue). These energy systems together determine the power at anaerobic threshold (grey). https://www.enduranceptc.com/eptc-review/flavia-oliveira-parks-crusher-in-the-tushar monthly 0.5 2023-08-23 https://images.squarespace-cdn.com/content/v1/616b8a75a7a23650b7b72888/9c1d5922-5090-486b-aa9c-7aab3276bebb/crusher-865504_1024x1024.jpeg EPTC REVIEW - Racing Journal feat.
