Effects of Strength Training on Muscle Fatigue Mapping from Surface EMG and Blood Metabolites.

The article presents a study on the effects of heavy resistance training on the relationship between power loss and surface electromyography (sEMG) indices and blood metabolite concentrations on dynamic exercise-induced fatigue with the same relative load, as in pretraining. It is said that association between EMG variables and manifestation of muscle fatigue during exercises have been related to the increase in surface spectrum to lower frequencies. It mentions that several attempts have been made to develop models that associate changes in sEMG. It also compares the track acute exercise-induced changes in muscle power output using sEMG variables and blood metabolite concentrations.
