Subjecting Elite Athletes to Inspiratory Breathing Load Reveals Behavioral and Neural Signatures of Optimal Performers in Extreme Environments

Background: It is unclear whether and how elite athletes process physiological or psychological challenges differently than healthy comparison subjects. In general, individuals optimize exercise level as it relates to differences between expected and experienced exertion, which can be conceptualized as a body prediction error. The process of computing a body prediction error involves the insular cortex, which is important for interoception, i.e. the sense of the physiological condition of the body. Thus, optimal performance may be related to efficient minimization of the body prediction error. We examined the hypothesis that elite athletes, compared to control subjects, show attenuated insular cortex activation during an aversive interoceptive challenge. Methodology/Principal Findings: Elite adventure racers (n = 10) and healthy volunteers (n = 11) performed a continuous performance task with varying degrees of a non-hypercapnic breathing load while undergoing functional magnetic resonance imaging. The results indicate that (1) non-hypercapnic inspiratory breathing load is an aversive experience associated with a profound activation of a distributed set of brain areas including bilateral insula, dorsolateral prefrontal cortex and anterior cingulated; (2) adventure racers relative to comparison subjects show greater accuracy on the continuous performance task during the aversive interoceptive condition; and (3) adventure racers show an attenuated right insula cortex response during and following the aversive interoceptive condition of non-hypercapnic inspirator

Creation of the American Heart Association Journals’ equity, diversity, and inclusion editorial board : the next step to achieving the 2024 impact goal

Approximately 2 years ago, the American Heart Association’s (AHA) National Board commissioned volunteer leaders to develop new goals to address health equity and to provide strong science to reduce health care disparities, including consideration of social determinants of health, structural racism, and rural health inequities. This effort resulted in the 2024 Impact Goal,1 which states that “every person deserves the opportunity for a full, healthy life. As champions for health equity, by 2024, the AHA will advance cardiovascular health for all, including identifying and removing barriers to health care access and quality.” One of the 10 commitments stated in the 2024 Impact Goal is to enhance the focus of our AHA scientific journals (https://www.ahajournals.org) on disparities, health equity, antiracism, community-engaged/community-based participatory research, and implementation science

With(out) pleasure: Desexualization, gender and sexuality at work

This article explores desexualization in massage therapy as a complex interaction between therapists and clients wherein sexual subjectivities are co-constructed, reified and in one case revised to highlight how workers can create a professional sexual identity in the spaces between desexualization and re-eroticization. Findings suggest that organizational mandates for desexualization as well as therapists' own framing maintains gendered subjectivities that paint men as aggressors and women as victims. It also offers, through the philosophy of one female therapist, an alternative to desexualization that seeks to encourage sexuality based on professionalism, respect and choice. A key implication of this study is that a more holistic and context-dependent view of work and workers is necessary for scholars and practitioners to understand the promise and perils of organizational desexualization
