Endpoint
Time to exhaustion
CAT:outcome/time-to-exhaustionreported in s
Method
Duration sustained at a fixed submaximal workload until volitional failure. Workload and modality recorded on the edge.
The method is part of the endpoint identity. Studies measuring the same quantity by a different method are held as separate endpoints.
Notes
Not interchangeable with a time trial. Open-ended tests at fixed load and fixed-distance time trials have different variability and are different endpoints.
Findings
1 finding from 1 compound, strongest first.
