Response of cardiac autonomic modulation after a single exposure to musical auditory stimulation

The acute effects after exposure to different styles of music on cardiac autonomic modulation assessed through heart rate variability (HRV) analysis have not yet been well elucidated. We aimed to investigate the recovery response of cardiac autonomic modulation in women after exposure to musical auditory stimulation of different styles. The study was conducted on 30 healthy women aged between 18 years and 30 years. We did not include subjects having previous experience with musical instruments and those who had an affinity for music styles. The volunteers remained at rest for 10 min and were exposed to classical baroque (64-84 dB) and heavy metal (75-84 dB) music for 10 min, and their HRV was evaluated for 30 min after music cessation. We analyzed the following HRV indices: Standard deviation of normal-to-normal (SDNN) intervals, root mean square of successive differences (RMSSD), percentage of normal-to-normal 50 (pNN50), low frequency (LF), high frequency (HF), and LF/HF ratio. SDNN, LF in absolute units (ms (2) ) and normalized (nu), and LF/HF ratio increased while HF index (nu) decreased after exposure to classical baroque music. Regarding the heavy metal music style, it was observed that there were increases in SDNN, RMSSD, pNN50, and LF (ms (2) ) after the musical stimulation. In conclusion, the recovery response of cardiac autonomic modulation after exposure to auditory stimulation with music featured an increased global activity of both systems for the two musical styles, with a cardiac sympathetic modulation for classical baroque music and a cardiac vagal tone for the heavy metal style.

Utilização de resíduos e derivados de madeira para confecção de uma guitarra elétrica

The residues generation is a quite serious problem in several industrial areas and also in the lumbering area. The search for the elimination or reduction of the volume of generated residues is endless, however limited, resulting in the search for a proper destination or better use, instead of simply burning it. A lot of uses and services are commonly proposed, but with low aggregated value to the residue. This work shows the usage viability of different discarded residues and wood composites in the production of an electric guitar. Cupiúba, ipê and jatobá residues have been used besides wood composites of pinus. The residues and wood composites have shown appropriate resistance, surfacing quality and design terms, and could be used to substitute the traditionally wood used in the production of the instrument as well as in other products of similar characteristics and with larger aggregated value.

The effects of auditory stimulation with music on heart rate variability in healthy women

OBJECTIVES: There are no data in the literature with regard to the acute effects of different styles of music on the geometric indices of heart rate variability. In this study, we evaluated the acute effects of relaxant baroque and excitatory heavy metal music on the geometric indices of heart rate variability in women. METHODS: We conducted this study in 21 healthy women ranging in age from 18 to 35 years. We excluded persons with previous experience with musical instruments and persons who had an affinity for the song styles. We evaluated two groups: Group 1 (n = 21), who were exposed to relaxant classical baroque musical and excitatory heavy metal auditory stimulation; and Group 2 (n = 19), who were exposed to both styles of music and white noise auditory stimulation. Using earphones, the volunteers were exposed to baroque or heavy metal music for five minutes. After the first music exposure to baroque or heavy metal music, they remained at rest for five minutes; subsequently, they were re-exposed to the opposite music (70-80 dB). A different group of women were exposed to the same music styles plus white noise auditory stimulation (90 dB). The sequence of the songs was randomized for each individual. We analyzed the following indices: triangular index, triangular interpolation of RR intervals and Poincaré plot (standard deviation of instantaneous beat-by-beat variability, standard deviation of the long-term RR interval, standard deviation of instantaneous beat-by-beat variability and standard deviation of the long-term RR interval ratio), low frequency, high frequency, low frequency/high frequency ratio, standard deviation of all the normal RR intervals, root-mean square of differences between the adjacent normal RR intervals and the percentage of adjacent RR intervals with a difference of duration greater than 50 ms. Heart rate variability was recorded at rest for 10 minutes. RESULTS: The triangular index and the standard deviation of the long-term RR interval indices were reduced during exposure to both music styles in the first group and tended to decrease in the second group whereas the white noise exposure decreased the high frequency index. We observed no changes regarding the triangular interpolation of RR intervals, standard deviation of instantaneous beat-by-beat variability and standard deviation of instantaneous beat-by-beat variability/standard deviation in the long-term RR interval ratio. CONCLUSION: We suggest that relaxant baroque and excitatory heavy metal music slightly decrease global heart rate variability because of the equivalent sound level.

A música associada às necessidades terapêuticas de pacientes com deficiência

The use of music and/or its elements (instruments, sound, rhythm, melody and harmony) in environments with people attended by public health centers, aims at promoting communication, facilitating the expression and the relationship in the first contact, hence favoring organization of standards and other relevant therapeutic objectives to assist physical, mental, social and cognitive needs of people, thus promoting the process of environmental adaptation, behavioral conditioning and social inclusion. The purpose of this project is to use music and its sound elements, as well as recreational activities, developed in stages called: socialization session, art workshop and complementary activities, with patients assisted at CAOE (Disabled People Dental Care Center) and their relatives. The objective is to provide them psychological wellbeing, inclusion to physical space, relaxation, stimulation of rhythmic and sonorous perceptions, memorization, emotions externalization, help and encouragement for the development of motor coordination during their daily activities of daily. Recreational activities, handling and contacting with musical instruments, broadcasting and producing sounds, stimulate cognitive capacity, interactivity and entertainment activities can greatly contribute to improve the behavioral reaction and adaptation of these patients, during their dental treatment.

Cultura, arte e sociedade: reflexões a partir da linguagem corporal da capoeira angola e suas linhas desenhadas no espaço

Dance-fight-game, art, religiosity, therapy, entertainment, ritual act, in short, "a way of being", are some of the various definitions/qualities attributed to the afro-brazilian cultural manifestation called "Capoeira Angola". Multivocal polysemic in its essence, Capoeira Angola is expressed in different languages which ranges from the types of touches of the musical instruments that make up the orchestra, through different types of songs, until we get the non-verbal communication established by the bodies of "capoeiristas" in the game and/or in the training body situation. The aim of this paper is to think of the line drawing in space, a significant problem in the execution of body movements of this practice. To address the relationship between line, efficiency and aesthetics of body movements, it is developed an ethnography in the Academy of João Pequeno de Pastinha-Sports Center of Capoeira Angola, based on anthropological interpretative approach, in which the concept of culture is semiotic.

Treino musical e capacidade da memória operacional em crianças iniciantes, veteranas e sem conhecimentos musicais

A memória operacional e a atividade musical ativam áreas encefálicas recíprocas e homólogas, contudo não há evidências se o treino musical pode ampliar a capacidade da memória operacional. Objetivo: Avaliar o desempenho do treino musical sob a memória operacional em crianças de 9 e 10 anos de idade, praticantes de treino musical e sem experiência musical. PARTICIPANTES: Crianças Iniciantes (n=20), Veteranas (n=20) e Grupo Controle (n=20). MATERIAIS: Instrumentos computadorizados para avaliação da memória operacional. RESULTADOS: Crianças veteranas apresentaram melhores pontuações no BCPR (Teste de Repetição de Pseudopalavras para crianças brasileiras) e em subtestes da AWMA (Avaliação Automatizada da Memória Operacional). CONCLUSÃO: O treino musical parece ter contribuído para o desenvolvimento da memória operacional em crianças veteranas no programa de treino musical.

O Punk não é só para o seu Namorado: esfera pública alternativa, processos de identificação e testemunho na cena musical Riot Grrrl

The Riot Grrrl movement started in mid-90s and it consists of girls who use rock as a tool of feminist political struggle. Besides using music as a central element of political identity, this movement is also characterized by the formation of an alternative public sphere (formed by fanzines, blogs and e-zines) that functions both as a way to spread their music and as identification trigger mechanism in relation to their political causes. The aim of this article is to study the instruments that these feminists bands - that deviate from the traditional feminist political movements - use to create identification with their audience, especially from an empirical research of e-zines published by these bands and from the communicative action of their leaders in social networks. It is possible to note that, despite other identification mechanisms, testimonies works as a socialization link which marks the alternative public sphere composed by publications made by Riot Grrrls. The testimony serves as a powerful arranger of collective identities, since it is presupposed in the recognition of a world in common, allocating identity as performative action.
