The Conconi test

Area of Science:

Exercise Physiology
Sports Science
Biomechanical Analysis

Background:

The Conconi test is a widely used incremental running test to determine the speed/heart rate (S/HR) relationship.
Assessing the repeatability and accuracy of this test is crucial for reliable physiological assessments.

Purpose of the Study:

To evaluate the repeatability of the speed/heart rate relationship derived from the Conconi test.
To compare the accuracy of visual analysis versus computer analysis in determining deflection points.

Main Methods:

75 subjects repeated the Conconi test twice to assess S/HR relationship repeatability.
Four variables (speed/heart rate of deflection, slope, intercept) were compared between tests.
65 subjects' data were used to compare visual vs. computer analysis of deflection points by observers with varying experience.

Main Results:

While minor variations exist in the linear S/HR relationship, the deflection points consistently converged between repeated tests.
Visual analysis of deflection points closely matched computer analysis, especially for experienced observers.
Less experienced observers showed some discrepancies in determining speed and heart rate of deflection compared to computer analysis.

Conclusions:

The Conconi test demonstrates good repeatability for identifying the deflection point.
Visual analysis is a reliable method for interpreting Conconi test results, with accuracy dependent on observer experience.
The findings support the validity of the Conconi test for physiological assessment in sports science.
