Our Services


We offer a selection of competitively priced services as a part of our broad fitness assessments.

Performance Metabolic Efficiency Assessment

Metabolic efficiency measures how well your body utilizes its fat stores as an energy source during exercise. Burning fat as fuel can be significantly improved by phasing nutrition with training. As an endurance athlete, ingesting as many calories as you are expending is impossible. The key is to improve your ability to effectively tap fat stores for fuel, and push utilization of this energy source out at increasing intensities. This can benefit every endurance athlete from road cyclists and trail runners to triathletes.

This test will inform you of:

  • Caloric expenditure at various heart rates, and pace or watts
  • Peak fat burning zone based on heart rate, and pace or watts
  • Lactate levels for your various metabolic zones
  • Methods to increase fat utilization and preserve carbohydrate stores, decreasing the amount of fuel replenishment required
  • Phasing nutrition with training to maximize fitness results
