Validation of a new calibration method for human muscle microdialysis at rest and during exercise.

abstract：PURPOSE:Topical application of nonivamide-nicoboxil cream to resting legs has been shown to enhance the level of oxygenated haemoglobin in leg muscles 15 min later. Here, we examined whether such application improves the performance of experienced cyclists in a subsequent 4-km time-trial. METHODS:Nine male cyclists [2...

But, surprisingly, the termination of a maximum exercise test often occurs in the absence of a VO(2) plateau. To explain this inconsistency, some have proposed that an oxygen limitatio...
