The Issues

  • Lactate profile curves depend heavily on the protocol used—making results from different tests difficult to compare.
  • Conventional lactate tests don’t provide VO₂max, even though it’s a critical marker for endurance and health.
  • VLamax, the key metric for anaerobic capacity, isn’t captured in traditional lactate tests and requires extra, non-validated sprint tests.
  • Conventional lactate tests don’t provide fat and carbohydrate combustion analysis, leaving you blind to critical fueling and FatMax data.
  • A simple right or left shift of the lactate profile curve doesn’t  provide insights into the training adaptation causing that shift.

INSCYD’s Solution

  • With INSCYD, you can follow any testing protocol you want—your results will be comparable across all tests.
  • INSCYD provides VO₂max directly from your lactate test—scientifically validated matching the accuracy of the best metabolic carts.

Real Results of Success

Turning Data into Gold: How INSCYD Powered Germany’s Olympic Swimming Success

Traditional swim testing demanded immense effort but provided only limited metabolic insights. The German Swimming Federation (DSV) partnered with INSCYD to change that—using physiology-driven diagnostics to unlock deeper athlete data and optimize training.

INSCYD Impact:

By unlocking detailed metabolic profiles, German coaches tailored training to target the exact physiological factors limiting performance. This data-driven approach led to historic success, including 3 medals at the Tokyo 2021 Olympics and multiple podium finishes at the 2024 Paris Olympics. The partnership continues to prove that smarter diagnostics fuel elite results.

“We can now quantify the effect of the training and plan the next stimulus much more specifically.”

160 MEDALS WITH 23 CHAMPIONS

Traditional methods focusing solely on VOmax and anaerobic threshold were not delivering consistent results. Coach Ben Tilus used INSCYD’s metabolic profiling to identify the anaerobic energy (VLamax) as the missing factor in his athletes’ performance, allowing for more targeted training strategies.

INSCYD Impact:

By understanding the balance between aerobic and anaerobic systems, Tilus was able to tailor workouts for optimal performance. This led to significant results, including over 160 medals won by his athletes and several state championships, proving that more accurate data drives better outcomes.

"After starting with INSCYD, it was like a snowball effect. We went from having 20 runners in the program winning about 30 medals last year. This year our athletes won 160 medals with 23 champions, 29 Runners-Up (2nd) and 22 third place finishes."

Qualified for the Tokyo Olympics in the Mixed Team Relay.

INSCYD was used to fine-tune the balance between VO2max and VLamax for each athlete, ensuring they were perfectly prepared for the demands of the mixed relay format. The lactate recovery/accumulation curve was particularly useful for creating individualized interval training.

INSCYD Impact:

The tailored training programs directly contributed to the team’s qualification for the Olympics, highlighting the effectiveness of a personalized approach to endurance training.

We use INSCYD to balance between VO2max and VLamax. This balance gives direction to the training schedule.

Enhanced race performance for a national 800-meter swimmer.

Conventional lactate testing suggested the swimmer needed aerobic improvement. However, INSCYD’s comprehensive metabolic profiling identified a high VLamax as the actual issue. Training was adjusted to target this specific area.

INSCYD Impact:

By focusing on reducing VLamax, the swimmer improved endurance and race outcomes, proving that addressing the correct physiological factors can transform performance.
