Purpose: Mountain running races are becoming increasingly popular, although our understanding of the particular physiology associated with downhill running (DR) in trained athletes remains scarce. This study explored the cardiorespiratory responses to high-slope constant velocity uphill running (UR) and DR. Method: Eight endurance athletes…

Compared to aerobic catabolism, the theories and experiments of anaerobic catabolism are not covered in depth in biochemistry education curricula. Anaerobic digestion (AD) is a feasible method for converting common organic compounds to renewable energy-methane that has drawn a great deal of attention in practical applications. In this study, we…

Learning metabolic pathways is vital for understanding biochemical processes and all of their implications for life. Their learning in the virtual environment is complex and generative learning strategies, such as the construction of online conceptual maps, can help in this process. This article presents a proposal for the collaborative…

Team-based learning (TBL) is an active learning method used in many educational institutions. However, there are few examples of its use in basic medicine, such as biochemistry in medical schools. This study used TBL to teach glucose metabolism to first-year medical students. The process was in four phases: preclass preparation, readiness…

Much research has been executed to investigate how altering focus of attention impacts performance and feelings of fatigue. Using a within-participant design, the present study examined how an associative and dissociative attentional in addition to an internal and external attentional dimension influenced the running economy of nonprofessional…

This preregistered, randomized field experiment tested the effectiveness of a brief deep breathing intervention on children's concurrent physiological arousal in naturalistic settings (N = 342; M[subscript age] = 7.48 years; 46% female; 53% Asian, 26% White; 21% other race/ethnicity). The treatment consisted of an animated video that introduced…

Purpose: The purpose of this study was to compare the acute effects of general warm-up (GWU) and GWU plus dynamic stretching (GWU + DS) on endurance running performance in well-trained male runners. Method: The endurance running performances of eight well-trained long-distance male runners were assessed on a treadmill after 2 types of intervention…

Purpose: The current study investigated diurnal cortisol dynamics in adults with and without aphasia, along with subjective reports of stress and measures of language production. Dysregulation of cortisol, a common biomarker of stress, is associated with cognitive dysfunction in different clinical populations. However, little is known about the…

Infant-mother behavioral synchrony is thought to scaffold the development of self-regulation in the first years of life. During this time, infants' and mothers' physiological regulation may contribute to dyadic synchrony and, in infants, dyadic synchrony may support infants' physiological regulation. Because the sympathetic nervous system (SNS)…

Objective: Alcohol-related facial flushing occurs in individuals who are unable to metabolize ethanol effectively and is associated with increased cancer risk. This study describes college students' understanding of the meaning of flushing for how much alcohol a person should drink and their use of over-the-counter medications and other strategies…

Maximal exercise capacity (W[subscript max]) and anaerobic threshold (A[subscript T]) are important tools used non-invasively to evaluate aerobic fitness levels and clinically possible risk. It has been shown that O[subscript 2] uptake to heartbeat ratio (O[subscript 2] pulse) at the maximal exercise test is an important parameter used to evaluate…

Objective: To investigate what social, psychological, personality, and behavioral factors affect overtime heart rate changes of college students. Participants: The daily heart rates of over 600 undergraduates at the University of Notre Dame were unobtrusively recorded via Fitbit devices from August 16, 2015, to May 13, 2017. Method: Latent…

The sex bias in autism diagnosis suggests the involvement of sex-specific endocrine mechanisms during prenatal development, but these hormones affect health throughout life. Therefore, the current study examined the association of autism and autistic traits with conditions and symptoms related to the sex-steroid system in adult women. In total,…

Objective: To assess the role of body mass index (BMI) and exercise levels in self-perception of critical thinking skills. Participants: Three hundred forty-seven students from an upper-division nutrition class over two consecutive years. Methods: A pre/post survey with a 15-week intervention assessed perceived critical thinking skills in a…

This case study investigated teachers' perceptions and experiences implementing heart rate (HR) monitors in high school physical education (PE) classes. Integrating technology, such as HR monitors, into the classroom influences the way teachers plan, instruct, assess, and motivate students in PE; however, successful integration is dependent upon…
