Cardiac autonomic responses induced by a single bout of exercise with flexible pole

Abstract

BackgroundFlexible poles are tools used to provide rapid eccentric and concentric muscle contractions. It lacks in the literature studies that analyze acute cardiovascular responses in different exercises performed with this instrument. It was investigated the acute effects of exercise with flexible poles on heart period in healthy women.MethodsThe study was performed on 32 women between 18 and 25 years old. It was evaluated the heart rate variability (HRV) in the time (SDNN, RMSSD and pNN50) and frequency domain (HF, LF and LF/HF ratio). The subjects remained at rest for 10 minutes. After the rest period, the volunteers performed the exercises with the flexible poles. Immediately after the exercise protocol, the volunteers remained seated at rest for 60 minutes and HRV were analyzed.ResultsIt was observed no significance changes in the time domain (SDNN: p = 0.14; RMSSD: p = 0.8 and pNN50: p = 0.86) and frequency domain indices (LF (nu): 0.4; LF (ms2): p = 0.34; HF (nu): p = 0.4; HF (ms2): p = 0.8 and LF/HF ratio: p = 0.3) between before and after single bout of exercise with flexible pole.ConclusionA single bout of exercise with flexible pole did not significantly change cardiac autonomic regulation in healthy women.

Chaotic analysis of heart rate dynamics after an exercise with flexible pole

“…30 The present study presents additional findings compared to previous studies published. [5][6][7][8] Dos Santos et al 8 evaluated the acute effects of flexible pole exercise on heart rate dynamics through time and frequency domain HRV indices. The authors did not report significant differences on SDNN, RMSSD, pNN50, LF (nu), LF (ms 2 ), HF (nu), HF (ms 2 ) and LF/HF ratio.…”

“…We also evaluated HRV in different post-exercise periods compared to the references cited. [5][6][7][8] While we investigated HRV in the initial five minutes post-exercise, previous studies evaluated it during the initial 60 minutes after exercise. In this context, we did not find significant change in complex behavior of HRV after an acute session of flexible pole exercise.…”

“…4 Recently, studies assessed HRV responses after a session of exercise with a flexible pole. [5][6][7][8] They investigated HRV immediately after an exercise with flexible pole through traditional time, frequency domain and geometric analysis. Nevertheless, the nonlinear Heart rate dynamics vs. flexible pole Antonio AMS the Autonomic Nervous System.…”
