Physiological Performance Analysis Software

A whole picture of physiology
to truly understand training and performance.

The human physiology that drives athletic performance and its adaptation to different training stimuli is complex and difficult to analyze — even the best human performance labs cannot capture a complete picture.


Without that complete picture, training decisions remain uncertain and outcomes often feel left to chance.


INSCYD solves this by making complete physiological analysis accessible to anyone — even without a laboratory

  • A virtual lab in your toolkit.
  • Gold Standard Accuracy

A complete human performance lab - just without the cost of it

Whether you run a full human performance lab, work with simple lactate tests, or coach remotely without any testing yet, you always receive a complete metabolic assessment.


INSCYD’s science-based algorithms replace equipment, time, and cost — delivering the most complete physiological profile possible from minimal data input.

Know what it takes to reach a goal — before you prescribe the training.

Before you decide what to train, INSCYD enables you to determine which physiological changes will have the greatest impact on your goal.


Not just whether something works — but how much it will change performance.


These effects can be quantified in advance with accuracy comparable to gold-standard methods reported in the scientific literature.

Base training on the physiology you want to change - instead of extrapolating it from thresholds.

Training should be built directly on the physiological systems — such as aerobic or glycolytic capacities — that need to improve to reach the goal.


Instead of extrapolating training zones from threshold, INSCYD enables you to build training zones by targeting the specific metabolic systems of interest.
 This includes VO₂max, VLamax, fat and carbohydrate utilization as well as recovery between intervals and lactate clearance rates.

What coaches and labs say about INSCYD

"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."
