Born high, born fast: Does highland birth confer a pulmonary advantage for sea level endurance?
Get PDFLess than 7% of the world\u27s population live at an altitude above 1500 m. Yet, as many as 67% of medalists in the 2020 men\u27s and women\u27s Olympic marathon, and 100% of medalists in the 2020 men\u27s and women\u27s Olympic 5000 m track race may have been born or raised above this otherwise rare threshold. As a possible explanation, research spanning nearly a quarter of a century demonstrates that indigenous highlanders exhibit pulmonary adaptations distinct from their lowland counterparts. These adaptations may then promote endurance performance. Indeed, healthy indigenous highlanders often exhibit a larger aerobic exercise capacity compared to sea-level residents who travel to high altitude. However, questions remain on whether high-altitude birth is advantageous for sea-level competitions. In this review, we ask whether being born at a high altitude generates an ergogenic advantage for endurance performance in the Summer Olympics—a venue that is generally held at sea level. In so doing, we distinguish between three groups of high-altitude residents: (i) the indigenous highlander, (ii) the highland newcomer, and (iii) the highland sojourner. Concentrating specifically on altitude-induced alterations to pulmonary physiology beginning in the perinatal period, we propose that if altitude-related maladaptations are avoided, genomic and developmental alterations accompanying highland birth may present benefits for endurance competitions at sea level
This is My Beloved: Embracing the Bridal Love of Jesus
No full textChristians throughout the ages have longed for a deeper, more intimate experience of Jesus\u27 love, to connect with him in a way that is impactful, satisfying, and touches the innermost places of the heart. Many found the answer by embracing Jesus not simply as their Savior, Teacher, and Lord, but also in his biblical role as the Bridegroom of the church. This Is My Beloved helps the reader respond to the bridal love of Jesus in practical, transformative ways by offering inspiring life stories and personal writings of Christians from the past and linking their encounters with the bride\u27s journey in the Old Testament book Song of Songs. Readers will learn to awaken their affections and satisfy some of their deepest desires by encountering profound intimacy and delightful friendship as the bride of Jesus. -- Back coverhttps://digitalcommons.pepperdine.edu/facultybooks/1302/thumbnail.jp
Loneliness Rates among Undergraduates according to the National College Health Assessment from 2008 to 2019
No full textThe present study documented undergraduate loneliness rates from Fall 2008 to Spring 2019. Participants consisted of undergraduates who completed the National College Health Assessment II (NCHA II) from Fall 2008 to Spring 2019. The NCHA II assessed loneliness by having students self-identify if they had felt “very lonely” within the last 12 months. From Fall 2008 to Spring 2019, 54.90% to 67.40% of undergraduates self-identified as feeling “very lonely” during these survey periods. Results indicated that the majority of undergraduates experienced loneliness and undergraduate loneliness rates had been increasing, even after controlling for gender, race, response rate, residential status (domestic versus international), type of school (public versus private), institutional type (two-year versus four-year), and campus size (\u3c 5,000; 5,000 - 20,000; and \u3e 20,000)
The Effect of Study Music Tempo on Short Term Memory Retention in Reading and Verbal Comprehension
Get PDFThis study experimentally investigated the effect of background music on retention as it relates to short term memory. Eighty undergraduate participants from various fields of study at Pepperdine University were randomly assigned to either listen to or read a preselected passage while listening to preselected excerpts of fast or slow tempo music. All participants were then asked to complete a 10 question test covering the material presented. There was a main effect specifically for music tempo in that participants who were exposed to background music at a slower speed while either reading or listening to a passage scored higher on the comprehension task. Consequently, the type of the retention task was less significant than the speed and tempo of the background music played. The results align with the original hypothesis and confirm that there is a correlation between music and memory retention. This study demonstrates how the presence and type of background music can potentially aid or hinder retention
