In an investigation about rescuer fatigue during chest compressions we plan include capillary lactate as a variable.
Es una cuestión muy difícil de poder objetivar, dado que lo que se mide en concentración plasmática del cuerpo. La concentración plasmática no nos permite cuantificar la cantidad de lactato producido por el músculo activo, salvo que sepamos cuánta es la masa de músculo activo. Además la relación entre nivel de lactato y nivel de fatiga, además de endeble es indivual y no sirve para comparar el nivel de fatiga entre dos personas a partir de los datos de lactatemía de cada una de esas dos personas
There are many papers from thirty years ago, but I don't recall them off hand. The problem is in the timing of lactate measurement and interpretation of what these values mean. Because lactate is a fuel as well as a temporary metabolite of muscle, what you are missing in capillary measurement of lactate is the time-dependent dynamics. The assumption that lactate causes muscle fatigue is not now considered valid, as it was once in the past.
