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

Background: Flexible 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.

Acute auditory stimulation with different styles of music influences cardiac autonomic regulation in men.

Background: No clear evidence is available in the literature regarding the acute effect of different styles of music on cardiac autonomic control.

Objectives: The present study aimed to evaluate the acute effects of classical baroque and heavy metal musical auditory stimulation on Heart Rate Variability (HRV) in healthy men.

Patients And Methods: In this study, HRV was analyzed regarding time (SDNN, RMSSD, NN50, and pNN50) and frequency domain (LF, HF, and LF / HF) in 12 healthy men.
