Affective Flexibility As A Developmental Building Block Of Cognitive Reappraisal: An Fmri Study, Jordan E. Pierce, Eisha Haque, Maital Neta

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Cognitive reappraisal is a form of emotion regulation that involves reinterpreting the meaning of a stimulus, often to downregulate one’s negative affect. Reappraisal typically recruits distributed regions of prefrontal and parietal cortex to generate new appraisals and downregulate the emotional response in the amygdala. In the current study, we compared reappraisal ability in an fMRI task with affective flexibility in a sample of children and adolescents (ages 6–17, N = 76). Affective flexibility was defined as variability in valence interpretations of ambiguous (surprised) facial expressions from a second behavioral task. Results demonstrated that age and affective flexibility predicted reappraisal ability, …

Reliability Of Isokinetic Tests Of Velocity‐ And Contraction Intensity‐Dependent Plantar Flexor Mechanical Properties, Matheus D. Pinto, Cody J. Wilson, Anthony D. Kay, Anthony J. Blazevich

Research outputs 2014 to 2021

“Flexibility” tests are traditionally performed voluntarily relaxed by rotating a joint slowly; however, functional activities are performed rapidly with voluntary/reflexive muscle activity. Here, we describe the reliabilities and differences in maximum ankle range of motion (ROM_max) and plantar flexor mechanical properties at several velocities and levels of voluntary force from a new test protocol on a commercially available dynamometer. Fifteen participants had their ankle joint dorsiflexed at 5, 30, and 60° s⁻¹ in two conditions: voluntarily relaxed and while producing 40% and 60% of maximal eccentric torque. Commonly reported variables describing ROM_max and resistance to stretch …

Localized Vibration: Effects On Flexibility, Louis Vince Lepak, Thomas W. Allen, Candace Robledo, David M. Thompson

School of Medicine Publications and Presentations

Background. Flexibility is an important component of physical conditioning used to improve performance and prevent injury. The application of vibration is one method that has been reported to increase flexibility. The preponderance of the literature reports the effects of whole-body vibration; fewer studies have investigated the effects of local vibration (LV) therapy.

Aims. To assess if LV affects spinal flexibility, the sit-and-reach test, or lower extremity range of motion measurements when compared to controls. To determine if the effects were specific to the site of LV application and if changes persisted between the follow-up visits.

Methods. Forty-three college students (age …

The Impact Of Power Training On Balance And Visual Feedback Removal, Juliana Bouton

Senior Honors Theses

Because power training has been known to augment stability, the purpose of this study was to assess whether the removal of visual input affects lower limb muscle power production in young women who are resistance trained to the same degree it affects the untrained. This provided insight as far as the need for resistance training protocols in a largely untrained visually impaired population. To study this, fourteen college-aged female participants (18-23 years) performed a seated double-leg press on a leg sled machine, isolating power production of the lower limbs. After establishing baselines, which involved finding an average of power produced …

Rumination And Performance In Dynamic, Team Sport, Michael M. Roy, Daniel Memmert, Anastasia Frees, Joseph R. Radzevick, Jean Pretz, Benjamin Noël

Management Faculty Publications

People high in rumination are good at tasks that require persistence whereas people low in rumination is good at tasks that require flexibility. Here we examine real world implications of these differences in dynamic, team sport. In two studies, we found that professional male football (soccer) players from Germany and female field hockey players on the US national team were lower in rumination than were non-athletes. Further, low levels of rumination were associated with a longer career at a higher level in football players. Results indicate that athletes in dynamic, team sport might benefit from the flexibility associated with being …
