BACKGROUND: Elastic bands are therapeutic tools widely used in rehabilitation. However, knowledge regarding autonomic cardiovascular overload during this type of resistance exercise is limited.
AIM: To evaluate the autonomic control of heart rate during an incremental exercise protocol with elastic bands in sedentary healthy young individuals.
DESIGN: Observational and transversal study.
SETTING: Young community.
POPULATIONS: Sedentary young women.
METHODS: Ten subjects were subjected to an exercise protocol involving bilateral shoulder flexion to 90° with various thicknesses of elastic bands; the exercise was performed for 36 uninterrupted repetitions with a 15 – minute rest interval between sets. During the exercise, the RR intervals (R-Ri) were collected and determined, the heart rate variability was analyzed.
RESULTS: All subjects completed the exercise protocol. Heart rate increased, and RR intervals decreased from the yellow elastic band onward. However, the square root of the sum of the square of the difference of RR intervals divided by the number of RR interval, standard deviation of the arithmetic mean of all normal RR intervals, and standard deviation of the RR interval instantaneous intervals of type I decreased significantly when performed with the green band onward (p < 0.05).
CONCLUSION: Exercise with progressive elastic load increases heart rate. However, the green elastic band induces less total and parasympathetic modulation heart rate variability. CLINICAL REHABILITATION IMPACT: This study increases the knowledge about the impact of elastic band in cardiac autonomic modulation in young females.
