EVALUACIÓN DEL VOLUMEN DE CARGA AGUDA-CRÓNICA Y SU RELACIÓN CON EL DOLOR MUSCULOESQUELÉTICO EN EL ENTRENAMIENTO DE FUERZA

Abstract

The research was carried out with the purpose of determining the acute-chronic load volume with musculoskeletal pain in strength training. The acute-chronic training load volume is an instrument that serves as a quantifier of the total amount of work performed by an individual. The acute load is the amount of training performed in the short term in order to know the recent effort and intensity, while the chronic load is that which represents the total amount of work in the long term, usually over a period of 4 weeks or more. In strength training it has been evidenced that most of the population presents musculoskeletal pain and this would be due to the fact that the subjects would be performing overtraining, poor load management, incorrect techniques, high loads, among other factors. Evaluating the acute:chronic load volume can help to optimi z e the individual's performance and prevent injuries. The present research is of a longitudinal correlational type with a quantitat i v e approach, the “Acute chronical workload ratio” (ACWR) method will be used to quantify the training load volume and relate it to the Numerical Pain Scale (NRS), the research consists of a prospective design focused on the relationship between trainin g load volume and musculoskeletal pain, the participants will be monitored every week for two consecutive months to obtain their results.Acute load volume analysis was performed and the resulting ACWR was found to be 0.92 in the first month and 0.93 in the second month, indicating a range in the optima l load ratio zone. With regard to pain assessment, the Numerical Pain Scale (NRS) was used, with a mean NRS of 2.80 indicating mild to moderate pain. In summary, in the results it was established that there is no increase of high loads therefore it was not related to musculoskeletal pain, due to the fact that the populati o n may be presenting pain that is associated to other external factors.
