Effects of a complementary strength training program on performance, internal training load, and stress tolerance in ballet dancers
Abstract
The aim of this study was to verify the effects of complementary strength training on the support of lower limbs and on the flexibility in classical ballet dancers. Besides that, there was a secondary goal, which was to monitor the training internal load and the tolerance to stress. Ten female ballet dancers (aged = 17,4 ± 2,4 years old) participated of the study. They were divided in two groups: an experimental one, with dancers who, in addition to the ballet sessions, participated of complementary training and a control group. Before and after four weeks, all the participants underwent physical evaluations of lower limb strength, flexibility tests and horizontal tests. The internal training load of the sessions was monitored by the effort subjective perception of the session, and the tolerance to stress was monitored by means of the DELTA questionnaire. The results pointed out to significant improvements for the experimental groups, in the 90° support test for both legs, However, in the control group, there was a significant worsening in the 90° support test, significant changes between pre and post training in horizontal impulsion, and in the angle of the support test. In relation to the training internal load, the values were higher in the experimental group compared to the control group, and the tolerance to stress was higher in the experimental group. Therefore, the complementary strength training applied in the study was effective in assisting the dancers to keep and/or to improve performance in lower limbs support strength and flexibility.
