Fitness Tests and Assessments

We offer a range of physiological tests to determine your fitness level, and to design exercise plans and training regimens personalized for you. Here's a sampling:

  • VO2max (Maximum Oxygen Consumption) – VO2max is the maximum capacity of a person's body to transport and utilized oxygen during exercise. It's considered the best indicator of cardiorespiratory fitness and is an excellent estimation of aerobic performance potential.
  • Lactate profile and metabolism – Measuring a person's blood lactate concentration is a very good indicator for "endurance" athletic performance. It provides an indirect measure of muscle metabolism during exercise and gives a snapshot of nutritional status.
  • Lung function test (spirometry) – This test can determine whether exercise-induced asthma (EIA) or allergies are restricting optimal lung function.
  • Metabolic profile and "crossover point" – By tracking how your body utilizes fats and carbohydrates at different exercise intensities, we determine "exercise zones" that pinpoint optimal weight loss practices. We can also determine the "crossover point" at which your body uses more carbohydrates than fats.
  • Anaerobic power assessment – One version of this test is customized for shorter-distance cyclists to measure ability to produce energy for short term, maximum efforts. Another assessment test uses a series of measured jumps to determine anaerobic power.

Why physiological testing?

Assessing an athlete's physiological status is crucial to planning specific, individualized training programs.

For competitive athletes, physiological testing can help ensure that the athlete reaches peak performance levels at the best possible point in the season.

Testing benefits recreational athletes too, by helping the performance lab design individualized exercise plans to optimize maximum fat utilization – so you lose weight and increase fitness efficiently.
