Understanding Laboratory Performance Testing And Data

As a data-rich sport, cycling is filled with riders discussing VO2Max, peak power output (PPO), and functional threshold power (FTP). These terms are associated with cycling performance, but how valuable are they and how can a laboratory test provide accurate data to measure these numbers?

What is a laboratory performance test?

A performance test provides information regarding the factors associated with cycling performance. The testing is typically conducted under controlled conditions in a laboratory environment. The testing procedure should provide cyclists and coaches with beneficial information.

Tests are valid if they measure what they claim to measure.

For example, performance tests for cyclists should produce data that accurately predicts performance. Reliability refers to the repeatability of the results. In other words, we would expect the same results if we repeated the same testing protocol on the same athlete, using the same equipment under the same conditions.

A laboratory-based test is more reliable than field testing, primarily due to its standardised protocol, equipment (accurate and calibrated) and consistent environmental conditions.

Why do we test?

Testing is done to accurately and objectively determine training zones, assess training status and physiological profile, as well as to evaluate performance improvements.
