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

No clear evidence is available in the literature regarding the acute effect of different styles of music on cardiac autonomic control. 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. 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. HRV was recorded at seated rest for 10 minutes. Subsequently, the participants were exposed to classical baroque or heavy metal music for five minutes through an earphone at seated rest. After exposure to the first song, they remained at rest for five minutes and they were again exposed to classical baroque or heavy metal music. The music sequence was random for each individual. Standard statistical methods were used for calculation of means and standard deviations. Besides, ANOVA and Friedman test were used for parametric and non-parametric distributions, respectively. While listening to heavy metal music, SDNN was reduced compared to the baseline (P = 0.023). In addition, the LF index (ms(2) and nu) was reduced during exposure to both heavy metal and classical baroque musical auditory stimulation compared to the control condition (P = 0.010 and P = 0.048, respectively). However, the HF index (ms(2)) was reduced only during auditory stimulation with music heavy metal (P = 0.01). The LF/HF ratio on the other hand decreased during auditory stimulation with classical baroque music (P = 0.019). Acute auditory stimulation with the selected heavy metal musical auditory stimulation decreased the sympathetic and parasympathetic modulation on the heart, while exposure to a selected classical baroque music reduced sympathetic regulation on the heart.

Pre-task music improves swimming performance

The purpose of this study was to investigate the effects of pre--task music on swimming performance and other psychological variables. A randomized counterbalanced within--subjects (experimental and control condition) design was employed. Eighteen regional level male swimmers performed two 200m freestyle swimming time trials. Participants were exposed to either 5min of self--selected music (pre--task music condition) or 5min of silence (control condition) and, after 1 minute, performed the swimming task. Swimming time was significantly shorter (--1.44%) in the pre--task music condition. Listening to pre--task music increased motivation to perform the swimming task, while arousal remained unchanged. While fatigue increased after the swimming task in both conditions, vigour, ratings of perceived exertion and affective valence were unaltered. It is concluded, for the first time, that pre--task music improves swimming performance.

Use of music and play in pediatric nursing care in the hospital context

Objective. To identify and analyze scientific publications on the use of music and play in pediatric nursing care in the hospital context. Method. In this bibliographic study, papers were sought that were published in Portuguese or English between 2004 and 2009 and included the descriptors: hospitalized child, childhood, child recreation, nursing team, nursing, pediatric nursing, alternatives therapies, music, music therapy, play and playthings, play therapy, playing. For the review, the bibliographic databases used were MEDLINE, ScIELO and LILACS. Results. Seventeen publications were obtained, among which: 59% adopted a quantitative method; mainly nursing developed the activities (88%); per type of article, reviews on the theme and assessments of clinical changes associated with the use of music and play were frequent (59% and 18%, respectively); and the utility of this kind of therapies in nursing care is acknowledged (94%). Conclusion. Play and music are useful therapies that can be used in nursing care for pediatric patients.
