Purpose: This study aimed to determine whether a simplified, and potentially more stable, acoustic-aerodynamic voice outcome ratio (ratio of sound pressure level [SPL] to subglottal pressure) is comparable to a traditional vocal efficiency measure (ratio of acoustic power to the product of average subglottal pressure and average phonatory airflow)…

The body is the very basis of children's self-growth and their understanding of the world. However, children's body experiences of growing up have rarely been studied. This paper uses a hermeneutic phenomenological approach to study the body experience of 35 kindergarten children aged 5-6 from Nanjing, China. We found that children's body…

Subtle instructional changes that direct attentional focus can lead to changes in performance, potentially hindering a fitness assessment. An external attentional focus has been found to improve motor performance, however less is known about instructional effects on performance and the physiological response during an isometric endurance test. To…

Temporomandibular Disorders are a prevalent group of disorders affecting the temporomandibular joints and surrounding structures, including the masticatory muscles, ligaments, and tissues. Voice pedagogy literature and social media suggest an incomplete understanding of TMDs among voice teachers, with no repository containing a synthesis of…

Purpose: Maximal heart rate (MHR) is an important physiologic tool for prescribing and monitoring exercise in both clinical and athletic settings. However, prediction equations developed in adults may have limited accuracy in youth. The purpose of this study was to systematically review and analyze the available evidence regarding the validity of…

Purpose: This study aims to investigate the effects of a 10-min vocal exertion task on voice and respiratory measures, to determine whether restorative strategies can mitigate these effects after cessation of exertion, and to assess whether these strategies continue to reduce these detrimental effects when vocal exertion is resumed. Method: A…

Just because food packaging, the textbooks, and teachers, all say food contains energy, students do not have to believe them. The author uses "The tale of the tortoise and his nose," which is available to read on this blog: https://oxygen-energy-life.blogspot.com, as a context for teaching about oxygen. This article outlines the adult…

Test anxiety is a widespread and mostly detrimental emotion in learning and achievement settings. Thus, it is a construct of high interest for researchers and its measurement is an important issue. So far, test anxiety has typically been assessed using self-report measures. However, physiological measures (e.g., heart rate or skin conductance…

Purpose: The aim of this study was to examine the influence of menstrual cycle phases (follicular, ovulatory, luteal, and ischemic) and hormone levels (estradiol, testosterone, progesterone, and neuropeptide Y) on vocal fold vibrations in reproductive and postmenopausal women. Method: Glottal area waveforms were extracted from high-speed…

Menstrual management is recognized as a critical issue for young people internationally. Relatively little published research explores issues pertaining to menstruation in school education. This paper is based on the results of an Australian survey of 5007 young women aged 13-25, which examined their experiences of menstruation and dysmenorrhea.…

Purpose: Amplitude modulations (AMs) are important for speech intelligibility, and deficits in speech intelligibility are a leading source of impairment in childhood listening difficulties (LiD). The present study aimed to explore the relationships between AM perception and speech-in-noise (SiN) comprehension in children and to determine whether…

Context: Sudden cardiac arrest is the leading cause of sport-related deaths in young athletes. Athletic training students must understand cardiovascular anatomy and physiology in addition to pathophysiology to appropriately care for patients with cardiovascular conditions. Objective: Describe a teaching technique to actively engage students in…

This study aims to evaluate the physical abilities of U15 age category football players in the Turkish Republic of Northern Cyprus. The Functional Movement Screening (FMS) tests and digital goniometer measurement values of the football players who voluntarily participated in the study and did not have any injury history were compared. The findings…

The movement of air into and out of the lungs is facilitated by changes in pressure within the thoracic cavity relative to atmospheric pressure, as well as the resistance encountered by airways. In this process, the movement of air into and out of the lungs is driven by pressure gradients established by changes in lung volume and intra-alveolar…

Positive emotional design has been shown to have an important impact on multimedia learning. However, before learning multimedia materials, students may inevitably be stressed by external factors such as learning uncertainties brought about by COVID-19, that can affect their final performance. Moreover, whether the principles of emotional design…
