Sex Differences With Aging In The Fatigability Of Dynamic Contractions, Tejin Yoon, Ryan E. Doyel, Claire Widule, Sandra K. Hunter

Exercise Science Faculty Research and Publications

This study determined the sex difference with aging in fatigability of the elbow flexor muscles during a dynamic fatiguing task, and explored the associated mechanisms. We compared fatigability of the elbow flexor muscles in 18 young (20.2 ± 1 years: 9 men) and 36 old adults (73.5 ± 1 years: 16 men) during and in recovery from repeated dynamic contractions (~ 60°/s) with a load equivalent to 20% of maximal voluntary isometric contraction (MVIC) torque until failure. Transcranial magnetic stimulation (TMS) was used to assess supraspinal fatigue (an increase in the superimposed twitch, SIT) and the peak rate of muscle …

The All-Embracing Frame: Distance In The Trinitarian Theology Of Hans Urs Von Balthasar, Christopher Hadley

Dissertations (1934 -)

The notion of distance plays a complex role in Hans Urs von Balthasar’s trinitarian theology. The infinite distance that metaphorically marks out the difference between God and creation serves Balthasar as a negative-theological guard against earthly projections in images of God. But this distance also structures the biblical, ascetical, and phenomenological imagery upon which trinitarian theology so often depends. The infinite distance between Father and Son in the unity of the Holy Spirit structures Balthasar’s richly symbolic vision of a divine infusion of grace into a suffering world. Not only is inner-triune distance a controversial notion, but it strikes some …

Age And Sex Differences In Steadiness Of Elbow Flexor Muscles With Imposed Cognitive Demand, Hugo M. Pereira, Vincent C. Spears, Bonnie Schlinder-Delap, Tejin Yoon, Kristy A. Nielson, Sandra Hunter

Exercise Science Faculty Research and Publications

Purpose: These studies determined (1) age and sex-related differences in steadiness of isometric contractions when high cognitive demand was imposed across a range of forces with the elbow flexor muscles (study 1) and, (2) sex differences in steadiness among older adults when low cognitive demand was imposed (study 2).

Methods: 36 young adults (18–25 years; 18 women) and 30 older adults (60–82 years; 17 women) performed isometric contractions at 5%, 30% and 40% of maximum voluntary contraction (MVC). Study 1 involved a high-cognitive demand session (serial subtractions by 13 during the contraction) and a control session …

Men Are More Likely Than Women To Slow In The Marathon, Robert O. Deaner, Rickey E. Carter, Michael J. Joyner, Sandra K. Hunter

Exercise Science Faculty Research and Publications

Studies on nonelite distance runners suggest that men are more likely than women to slow their pace in a marathon.

Purpose: This study determined the reliability of the sex difference in pacing across many marathons and after adjusting women's performances by 12% to address men's greater maximal oxygen uptake and also incorporating information on racing experience.

Methods: Data were acquired from 14 US marathons in 2011 and encompassed 91,929 performances. For 2929 runners, we obtained experience data from a race-aggregating Web site. We operationalized pace maintenance as the percentage change in pace observed in the second half of the marathon …

Creative Women In Peru: Outliers In A Machismo World, Marta Mensa Torra, Jean M. Grow

College of Communication Faculty Research and Publications

Gender segregation begins early and is reinforced within the workplace. Advertising creative departments appear to have extreme gender segregation with women representing just 20% of all those working within creative departments worldwide. Yet, creativity does not depend on gender. Thus, the underrepresentation of women is particularly troubling. In Peru women comprise 3% to 10.4% of all people working in advertising creative, which suggests the situation for creative women in Peru is dire. In order to understand this phenomenon, and with the hope of finding solutions, this study uses in-depth interviews to explore the experiences of Peruvian women working in advertising …
