The question of the richness (or sparseness) of conscious experience has evoked ongoing debate and discussion. Claims for both richness and sparseness are supported by empirical data, yet they are often indirect, and alternative explanations have been put forward. Recently, it has been suggested that current experimental methods limit participants' responses, thereby preventing researchers from assessing the actual richness of perception.

The replication crisis in experimental psychology and neuroscience has received much attention recently. This has led to wide acceptance of measures to improve scientific practices, such as preregistration and registered reports. Less effort has been devoted to performing and reporting the results of systematic tests of the functioning of the experimental setup itself.

Article Synopsis
  • The study aimed to analyze the prevalence of sickle cell trait (SCT) among student-athletes in NCAA institutions, investigate common screening methods, and assess the health services available.
  • The results indicated that historically Black colleges and universities (HBCUs) had a higher prevalence of SCT (4.9%) compared to non-HBCUs (1.1%), and more HBCU athletes provided their own screening.
  • Additionally, a majority of institutions have policies for managing exertional sickling, but none included strength and conditioning coaches in their development, highlighting a need for improved collaboration and resource allocation in athletics.

Objective: An emergency action plan (EAP) is a written document detailing the preparations and on-site emergency response of health care professionals and other stakeholders to medical emergencies in the prehospital setting. The EAP is developed to address any type of catastrophic injury response and should not be condition specific. The objective of this National Athletic Trainers' Association position statement is to provide evidence-based and consensus-based recommendations for developing and implementing an EAP for sports settings.

The study of consciousness has developed well-controlled, rigorous methods for manipulating and measuring consciousness. Yet, in the process, experimental paradigms grew farther away from everyday conscious and unconscious processes, which raises the concern of ecological validity. In this review, we suggest that the field can benefit from adopting a more ecological approach, akin to other fields of cognitive science.

Background: The National Federation of State High School Associations provides recommendations regarding health and safety policies; however, policy development is governed at the state level. Given interstate differences in governance, the primary purpose was to describe processes that State High School Athletic Associations (SHSAAs) utilize to develop a new policy. The secondary objective was to determine what methods associations use to implement new policies.

Unconscious processing has been widely examined using diverse and well-controlled methodologies. However, the extent to which these findings are relevant to real-life instances of information processing without awareness is limited. Here, we present a novel inattentional blindness (IB) paradigm in virtual reality (VR).

The purpose was to describe wet bulb globe temperature (WBGT) throughout a high school fall athletic season (August to November) after a state-wide mandate requiring schools to use a WBGT-guided activity modification table with categories (AMTC). A cross-sectional research design utilized 30 South Carolina high schools. The independent variables were region (upstate, midlands, and coastal), sport (football, tennis, cross-country), month, start times (7-10 am, 10 am-3 pm, 3-6 pm, and 6-9 pm), and event type (practice, competition).

The relationship between conscious experience and brain activity has intrigued scientists and philosophers for centuries. In the last decades, several theories have suggested different accounts for these relationships. These theories have developed in parallel, with little to no cross-talk among them.

Background Literature examining emergency medical services (EMS) activations for sport-related injuries is limited to the pediatric, high school, and collegiate student-athlete populations, excluding older individuals and recreational athletes. The purpose of this study was to examine EMS activations for sport-related injuries using the National EMS Information System Database from 2017-2018. Methods Data were obtained using the National EMS Information System Database from 2017-2018.

Current methods of concussion assessment lack the objectivity and reliability to detect neurological injury. This multi-site study uses combinations of neuroimaging (diffusion tensor imaging and resting state functional MRI) and cognitive measures to train algorithms to detect the presence of concussion in university athletes. Athletes (29 concussed, 48 controls) completed symptom reports, brief cognitive evaluation, and MRI within 72 h of injury.

Article Synopsis
  • The study aimed to examine how whole body vibration affects human bone density and related biomarkers, utilizing data from various research databases up to November 2021.
  • A meta-analysis of 30 trials found that whole body vibration improved bone density, particularly in healthy and postmenopausal women, but did not significantly affect biomarkers for bone formation or resorption.
  • The findings suggest that whole body vibration could serve as a non-drug therapy to help reduce osteoporosis risk in postmenopausal women, although more research is required to understand the mechanisms involved.

The dynamics of American youth football make it critical to ensure that helmets are appropriately fit to decrease the risk of injuries. Currently, there is only one researcher-developed checklist to determine helmet fit, and psychometric testing is lacking; therefore, the aim of this work was to determine the validity of the checklist. The 13-item checklist was used to measure helmet fit in 267 youth football players prior to the start of the season.

This study evaluated emergency medical services (EMS) providers' knowledge of exertional heat stroke (EHS) and assessed current EMS capabilities for recognizing and managing EHS. EMS providers currently practicing in the United States were recruited to complete a 25-item questionnaire. There were 216 questionnaire responses (183 complete) representing 28 states.

Article Synopsis
  • This study investigates the impact of having athletic trainers (ATs) during basic combat training (BCT) on the frequency and nature of sick call visits and referrals to Troop Medical Clinics (TMC) in the U.S. Army.* -
  • Conducted at Fort Jackson, the study documented 14,304 sick call visits over a year, finding a high number of physical injury-related visits, particularly among younger, female soldiers. It also compared three conditions: control (no AT), full-time medic, and part-time athletic trainer.* -
  • Results showed that soldiers with ATs had significantly higher odds of returning to duty rather than being referred to TMC, with an overall return on investment of over $23 million,

In the ongoing research of the functions of consciousness, special emphasis has been put on integration of information: the ability to combine different signals into a coherent, unified one. Several theories of consciousness hold that this ability depends on - or at least goes hand in hand with - conscious processing. Yet some empirical findings have suggested otherwise, claiming that integration of information could take place even without awareness.
