Convergent validity of a simplified device and relationship between blood lactate and salivary lactate after a vertical squat jump in healthy non-athletes

[Purpose] The aims of this study were 1) to examine the convergent validity between Lactate pro 2 and a standard JCA-BM 8000 automatic analyzer using salivary lactate 2) investigate relationship blood levels after vertical squat jump. [Participants Methods] Healthy non-athletes participated in observational study. participants performed jump for 1 min 30 s. Blood measured before exercise Pro 2. [Results] intraclass correlation coefficient was 0.773, which can be considered as substantial validity. However, some samples, level out measurable range, numerical values could not obtained. cross-correlation function 0.535 at lag 0 0.750 1, indicated 5-min values. [Conclusion] Salivary easily 2, although its sensitivity needs resolved. Further research is required level, collected non-invasively, used an alternative parameter level.
