All of these have a high protocol dependence when presented as work rate (as below) rather than VO2. Poole et al. Topical review. The anaerobic threshold: 50+ years of controversy.

Development of non-invasive estimation of LT by gas exchange has greatly enhanced the application of concepts in La− metabolism to both physical training and clinical settings.  1. Why is anaerobic threshold important? 2. What are some protocol considerations for threshold tests? Review questions 3. How do we interpret and use the results of threshold tests? 4. What are the implications of threshold tests for training and competition?  Now that we have reviewed anaerobic threshold testing, what is next? - Topic: Application of Threshold Data NEXT - Chapter: NA - See also: CLASS… - CourseLink
