Sample report


Arrive for your Lactate Threshold test in clothing and shoes you normally use for exercise. You will be running on a treadmill or cycling on a cycle ergometer, depending on your preferred exercise. Exercise intensity is increased in periods of 3-5 minutes, with blood samples taken with a finger stick at the end of each period. The process continues until blood lactate concentration increased significantly. The test takes somewhere between 8 and 15 minutes.


 The lactate threshold test is a good predictor of athletic endurance. Lactate threshold is the point during physical activity in which blood lactate builds up faster than your body is able to remove it. With training, athletes can increase their lactate threshold and can exercise at higher intensities for longer.


A Certified Exercise Physiologist will review your results. You will receive online access to your results (test results with interpretation) within one business day.



Prior to the test you will undergo a spirometry test to evaluate lung function to ensure you can safely perform exercise testing. The spirometry test is a safe, painless, and quick test. You have the choice of performing the test on a treadmill or cycle ergometer, which is similar to a stationary bicycle.  During the test, you may be connected to a metabolic cart that measure the amount of oxygen that you breathe in and the amount of CO2 that your body produces through your breathing. You will then complete a short warm up. 

During the test, your blood pressure, heart rate, and heart activity will be monitored for safety. During this test, the intensity will gradually increase and you will be required to work harder and harder until, ultimately, you are working at your maximal capacity. This should take somewhere between 8 and 15 minutes. Once you reach the point at which you cannot work any harder, the test will be complete.  


 How Must I prepare?

  • Fill out an intake form and send it back to us before booking your appointment to ensure you can safely complete this test.

  • Do not exercise 24 hours prior to your appointment.

  • Make sure you’re properly hydrated and nourished before the evaluation; though not a full training workout, you will be performing at progressive exercise intensities for 8-15 minutes

  • Do not eat a heavy meal for 2-3 hours prior to your appointment. Light snacks are acceptable if needed.

  • Wear the shoes you normally train in.

 How Often Should I test?

There is no set time frame that we recommend that our clients retest, but many like to retest throughout their training for endurance events. By performing several tests, they can see if their training is effective or if they need to make adjustments.
