Abstract:
Objectives
To compare performance and physiological responses derived from a new intermittent field test (Test3L) with a standard continuous test (TestVAM), and to examine its reproducibility.
Methods
A first part (n = 7) allowed defining the maximal aerobic speed (MAS3L) equations derived from Test3L. A second part allowed validating MAS3L in 43 runners, divided into three performance groups: G1 beginners (n = 22), G2 trained athletes (n = 14), and G3 elite (n = 7). The 43 runners performed the Test3L twice to measure its reproducibility.
Results
The MAS values measured by the TestVAM (MASVAM) were not significantly different from MAS3L, for each performance group taken individually or as a whole (3Gr). The difference between MASVAM and MAS3L varied between 0.2 and 0.4 km.h on average. Similarly, no significant maximum heart rate (HRmax) differences were found between both tests. In contrast, blood lactate concentration (LA) was significantly higher in TestVAM compared to Test3L. The total duration of TestVAM was 2.74, 3.02, 2.55, and 2.57 times longer for 3Gr, G1, G2, G3, respectively compared to Test3L (P < 0,01). There were no significant differences in MAS, HRmax and LA between the test–retest procedures for Test3L.
Conclusion
Hence, it is suggested that the MAS and HRmax derived from Test3L can be used when designing training programs. However, caution must be taken with regard to LA. Additionally, Test3L is more or less 2.5 times shorter than TestVAM and has a high reproducibility.
