Changes of future actors ECG parameters during different genre roles
2014
Future actors – current art students – are an overlooked minority population, whose dynamic health processes have not been studied enough. Therefore, the aim of the study was to assess dynamic characteristics of Lithuanian Academy of Music and Theatre students’ ECG parameters during different genre roles. Results of the study revealed that the discriminant of the regulatory and supplying systems was decreasing through different stages of the research. Also, the results showed that average discriminant values were significantly different only during the first stage - post-isometric muscle relaxation (p<0,05). Both – during different genre roles and autogenic training – statistically significant differences were not found (p≥0,05).
Creative Flow and Physiologic States in Dancers During Performance
Frontiers in Psychology, 2020
Pre-professional and professional dancers (n = 60) participated in this ambulatory psychophysiology study that investigated performance flow and heart rate and autonomic nervous system (ANS) function during three time periods: baseline rest, performance, and post-performance rest. To gather these results, the psychophysiology laboratory traveled to the concert hall to collect data on dancers. The self-report Flow State Scale (FSS) measured global flow, challenge-skill balance, sense of control, and autotelic experiences; it addresses important features of the creative experience of performing artists. These data were collected immediately following the performance. The flow measures were compared with physiologic responses to performance [heart rate, pre-ejection period (PEP), root mean square differences of successive R-R (heartbeat) intervals (RMSSD), cardiac autonomic balance, and cardiac autonomic regulation]. The regression analyses indicated that greater sympathetic nervous system (SNS) activation with performance (PEP change from base to performance) explained 8.8% of the variance in sense of control, whereas less cardiac autonomic regulation explained 13.8% of the variance in autotelic experiences. The sample was then divided into high and low flow groupings and four autonomic groups. During performance, the high autotelic group and high sense of control group had a higher distribution of dancers with co-inhibition of both ANS branches than had the low autotelic and sense of control groups who employed more co-activation of both ANS branches (chi-square analyses). These novel findings add to the growing information about the interaction of both branches of the ANS during creative performance flow states.

AIMS: Musical theatre (MT) combines acting, singing, and dancing within a performance. The purpose of the current study was two-fold: 1) to report on the cardiorespiratory fitness of pre-professional MT dancers, and 2) to examine the cardiorespiratory demand of singing whilst dancing. METHODS: Twenty-one participants (16 females, 5 males; age 20±1.23 yrs; height 169.1±9.24 cm; weight 62.7±10.56) in their final year of pre-professional training volunteered for the study. All participants performed a maximal aerobic capacity test on a treadmill using a portable breath-by-breath gas analyser. Nine participants completed a 4-minute section from Chorus Line twice, singing and dancing and just dancing, in a randomised order whilst wearing the same portable gas analyser. Blood lactate was measured at the end of each trial. RESULTS: Male participants had significantly greater peak oxygen consumption (M vs F, 67.6±2.30 vs 55.6±4.42 mL/kg/min, p<0.001) and anaerobic threshold (% of peak VO...

A comparative study was used to analyze the difference in autonomic balance assessed by time and frequency domain parameters of heart rate variability (HRV) between students athletes and non-sportsmen. Five-minute digital ECG trays were recorded in 21 students - athletes, 10 basketball players recruited from first league clubs of No- vi Sad and the Serbian representatives and 11 rowers from the Novi Sad rowing club 'Danubius'. The control group was formed by 15 non-sportsmen, students of the Medical faculty in Novi Sad who underwent the same registrations. Time and frequency-domain of HRV were analyzed by a software developed by the company 'Neurosoft', VNS-Spektr, Ivanovo, Russia. Resting heart rate in athletes was significantly lower (p < 0.01) than in non-sportsmen. In time-domain parameters HRV significantly higher values were present in the group of sportsmen as opposed to non-sportsmen RRNN (p < 0.01), RMSSD (p < 0.02) and pNN50 (p < 0.01). In frequ...

Background: Heart rate variability (HRV), generated from an electrocardiogram (ECG), can be used to evaluate the autonomic nervous system (ANS). Heart rate changes during different physical activities are due to changing involuntary regulation. Objective: The main aim of the current study is to explore the ANS by analyzing linear HRV parameters, so that clinicians can preliminarily explore ANS function using ECG analysis with their patients. Patients and methods: A total of 15 student volunteers were recorded. Data was collected for 5 minutes for each supine and standing position. The R-peak obtained from an ECG is used to assess the RR-peak, which is also required for HRV analysis. Linear HRV parameters with different time-domain indices and frequency-domain indices are interpreted in 2 body positions. Results: We discovered that the RR interval is longer in the supine position than in the standing position (952.8±181.6 vs. 771.9±164, respectively; P<0.05), and that in comparison to supine position, when standing as opposed to when lying down, the heart rate is higher (81.7±10.2 vs. 65.8±9.1, respectively; P<0.05), where the body is more relaxed. This affects ANS, and stress index values, which are low before increasing in the standing position, starting in the supine position (5.7±2.4 vs. 9.5±2.7, respectively; P<0.05). Conclusion: We conclude that there is a relationship between HRV and the sympathetic system in different positions, where when moving from supine to standing, the values of HRV changes (increases) and, therefore, the stress index changes (increase) and, from this, we note the change (value increase) in ANS.

Background: Changes in heart rate during rest-exercise transition can be characterized by the application of mathematical calculations, such as deltas 0-10 and 0-30 seconds to infer on the parasympathetic nervous system and linear regression and delta applied to data range from 60 to 240 seconds to infer on the sympathetic nervous system. The objective of this study was to test the hypothesis that young and middle-aged subjects have different heart rate responses in exercise of moderate and intense intensity, with different mathematical calculations. Methods: Seven middle-aged men and ten young men apparently healthy were subject to constant load tests (intense and moderate) in cycle ergometer. The heart rate data were submitted to analysis of deltas (0-10, 0-30 and 60-240 seconds) and simple linear regression (60-240 seconds). The parameters obtained from simple linear regression analysis were: intercept and slope angle. We used the Shapiro-Wilk test to check the distribution of data and the "t" test for unpaired comparisons between groups. The level of statistical significance was 5%. Results: The value of the intercept and delta 0-10 seconds was lower in middle age in two loads tested and the inclination angle was lower in moderate exercise in middle age. Conclusion: The young subjects present greater magnitude of vagal withdrawal in the initial stage of the HR response during constant load exercise and higher speed of adjustment of sympathetic response in moderate exercise.
Physiological Measurement of Performers' Tension and its Utilization for Media Control
1998
In performing art, in addition to contents, performers' tension or elaboration is transferred to the audience. This plays a very important role in forming artistic impression. The authors have been engaged in producing interactive art utilizing gesture sensors. Using the sensing unit originally designed for gesture sensors, we have measured a performer's physiological data as the index of tension. We also measured and investigated concerning how the tension is conveyed to the audience using physiological sensors. This paper describes results of the experiments and discusses the effectivity of tension and physiological data in the performing art.
