RELATIONSHIP BETWEEN COMPETITION SIMULATION AND TRAINING ON STRENGTH AND DAMAGE INDICATORS IN JIU-JITSU

RELACIÓN ENTRE SIMULACIÓN DE COMPETICIÓN Y ENTRENAMIENTO A TRAVÉS DE INDICADORES DE FUERZA Y LESIONES EN EL JIU-JITSU

ABSTRACT

Background:

The relationship between training and competition is very important and aims at a more specific and adequate preparation in Jiu-Jitsu.

Problem and objective:

To evaluate the relationship between training and competition through indications of injury and muscle strength.

Methods:

The study sample included nine subjects (22.54 ± 2.77 years of age) who were submitted to the following two conditions: 1) training simulation and 2) competition simulation.

Results:

There were no significant differences in the countermovement jump (CMJ) test. However, 48 hours after training there was an indication of values higher than the post-competition ones. Creatine kinase (CK) indicated significant differences in muscle damage after competition in relation to the other conditions and moments (p <0.01) with a high effect. Lactate dehydrogenase (LDH) showed differences in the moments before, during, and after both competition and training conditions (p <0.05) with a high effect. The power of the upper limbs (PUL) showed a medium correlation at 24h (> 0.55) and 48h (0.47) after the intervention. There was high correlation (> 0.70) for all conditions in the squat jump (SJ). LDH showed a high correlation (> 0.70) at 48 hours.

Conclusion:

There was a good correlation between training and competition simulation, which tends to indicate that the training model used in the study properly prepare Jiu-Jitsu athletes for the demands of competition. Level of evidence I; High-quality randomized clinical trial with or without a statistically significant difference, but with narrow confidence intervals.
