The continuing U.S. demographic shifts provide a substantial rationale for a corresponding transformation in the culture and climate of academic departments in higher education. In part, the response to the change is to increase the representation of people of color and others who have been historically absent from professional areas fed by the Kinesiology pipeline. However, the greater challenge is to understand and therefore, alter the internal culture. An intentional effort toward a culture of inclusion and full participation provides a working platform to transform existing practices and to cultivate policies from which emerging practices will offer opportunities for success. The understanding of the multiple identities of those within Kinesiology and the society served, the portals and gaps within the systemic architecture, and the methods of creating a multicultural organization—all play significant roles in contributing to change and transformation. Enlightened catalytic change agents must adopt new inclusive paradigms to prepare 21st century professionals with adaptive ideologies and behaviors for resolving future issues and challenges.

This study examines the historical significance of Jang Gwon’s activities in the sport promotion carried out by Korea’s YMCA. At its birth, the Korean YMCA’s sport promotion was closely linked with the Korean nationalist movement under Japanese colonial rule, and this link was most evident around 1920, when Jang Gwon worked as a judo master. Citing the Sokol movement in Czechoslovakia, Jang Gwon took initiatives to enlighten Korean people’s consciousness and popularize sports, including judo and basketball, across the country through the Korean YMCA’s sport promotion. In particular, Jang Gwon introduced modern judo—formally known as Gangdogwan (Kodokan judo), initiated by Jigoro Kano—in Korea and took initiatives to establish the Korean Basketball Association and the Korean Basketball Referee Association. Through the Korean YMCA’s sport promotion, Jang Gwon motivated the Korean people to aspire to liberation and independence from Japanese colonial rule. Moreover, amid the prevailing social climate, in which physical activities were discouraged due to the influence of Neo-Confucianism, he provided a paradigm shift that called for “sport for all,” which enabled the modernization of sports and physical education in Korea.

There is evidence that adolescence is a critical period in development, most likely involving important modifications of the body schema and of the sensorimotor representations. The present study addressed this issue, by investigating the differences between adolescents and adults regarding the integration of proprioceptive information at both perceptual and postural levels and the visual recognition of human movement. Proprioceptive integration was examined using muscle-tendon vibration that evoked either a postural response or an illusory sensation of movement. The ability to recognize human movement was investigated from a paradigm where the participants had to discern between human movements performed with and without gravity. The study produced three main findings. First, the adolescents had larger postural responses to tendon vibrations than the adults, with visual information enabling them to reduce this exaggerated postural reaction. Second, the adolescents had a greater illusory perception of movement compared with the adults. Third, the adolescents had the same perceptual ability as adults in the human movement perception task. In conclusion, we were able to highlight notable differences between adolescents and young adults, which confirms the late maturation of multisensory integration for postural control and the privileged visual contribution to postural control.

Context: Transcranial magnetic stimulation (TMS) may provide important information regarding the corticospinal mechanisms that may contribute to the neuromuscular activation impairments. Paired-pulse TMS testing is a reliable method for measuring intracortical facilitation and inhibition; however, little evidence exists regarding agreement of these measures in the quadriceps. Objective: To determine the between-sessions and interrater agreement of intracortical excitability (short- and long-interval intracortical inhibition [SICI, LICI] and intracortical facilitation [ICF]) in the dominant-limb quadriceps. Design: Reliability study. Setting: Research laboratory. Participants: 13 healthy volunteers (n = 6 women; age 24.7 ± 2.1 y; height 1.7 ± 0.1 m; mass 77.1 ± 17.4 kg). Intervention: Participants completed 2 TMS sessions separated by 1 wk. Main Outcome Measures: Two investigators measured quadriceps SICI, LICI, and ICF at rest and actively (5% of maximal voluntary isometric contraction). All participants were seated in a dynamometer with the knee flexed to 90°. Intracortical-excitability paradigm and investigator order were randomized. Bland-Altman analyses were used to establish agreement. Results: Agreement was stronger between sessions within a single investigator than between investigators and for active than resting measures. Agreement was strongest for resting SICI and active ICF and LICI between sessions for each investigator. Conclusions: Quadriceps intracortical excitability may be measured longitudinally by a single investigator, though active muscle contraction should be elicited during testing.

We used amplitude modulation of cutaneous reflexes during leg cycling as a paradigm to investigate neural control mechanisms regulating forward (FWD) and backward (BWD) rhythmic limb movement. Our prediction was a simple reversal of reflex modulation during BWD leg cycling and context-dependent reflex modulation. Cutaneous reflexes were evoked by electrical stimulation delivered to the superficial peroneal (SP) and distal tibial (TIB) nerves at the ankle. EMG recordings were collected from muscles acting at the hip, knee, and ankle. Kinematic data were also collected at these joints. Cutaneous reflexes were analyzed according to the phase of movement in which they were evoked. When functional phases (i.e., flexion or extension) of cycling were matched between FWD and BWD, background EMG and reflex modulation patterns were generally similar. The reflex patterns when compared at similar functional phases presented as a simple reversal suggesting FWD and BWD cycling are regulated by similar neural mechanisms. The general reflex regulation of limb trajectory was maintained between cycling directions in accordance with the task requirements of the movement direction.

Previous research demonstrates that infants adapt and plan their actions based on object weight, but fewer studies have investigated how infants’ understanding of object weight shapes their understanding of physical events. The present study investigates 10-month-old infants’ understanding of the effect of object weight in support events—specifically, that object weight impacts whether a supporting surface will become compressed or not—and its relation to motor development. In Experiment 1, using an action task, we found that infants infer an object’s weight based on whether it compresses a supporting surface, as demonstrated by reaches to the light object following the support event. In Experiment 2, using a violation-of-expectation paradigm, we found that infants generate predictions for the outcome of support events involving heavy and light objects (i.e., they expect heavy, but not light, objects to compress a supporting surface), as demonstrated by longer looking to inconsistent events relative to consistent. Neither experiment found relations with infants’ motor development. These findings demonstrate that infants invoke a concept of object weight when interpreting and predicting the outcomes of physical events and that the ability to reason about object weight as a causal factor in physical events is relatively sophisticated in infancy.

A defining element of coaching expertise is characterised by the coach’s ability to make decisions. Recent literature has explored the potential of Naturalistic Decision Making (NDM) as a useful framework for research into coaches’ in situ decision making behaviour. The purpose of this paper was to investigate whether the NDM paradigm offered a valid mechanism for exploring three high performance coaches’ decision-making behaviour in competition and training settings. The approach comprised three phases: 1) existing literature was synthesised to develop a conceptual framework of decision-making cues to guide and shape the exploration of empirical data; 2) data were generated from stimulated recall procedures to populate the framework; 3) existing theory was combined with empirical evidence to generate a set of concepts that offer explanations for the coaches’ decision-making behaviour. Findings revealed that NDM offered a suitable framework to apply to coaches’ decision-making behaviour. This behaviour was guided by the emergence of a slow, interactive script that evolves through a process of pattern recognition and/or problem framing. This revealed ‘key attractors’ that formed the initial catalyst and the potential necessity for the coach to make a decision through the breaching of a ‘threshold’. These were the critical factors for coaches’ interventions.

This article reviews the essential components of a practical, evidenced-based approach to the management of sport-related concussion in an ambulatory care setting. The model presented is based on the core philosophy that concussion assessment and management be approached from the biopsychosocial perspective, which recognizes the medical/physiological, psychological, and sociological factors that influence recovery and outcome following concussion. Based on the biopsychosocial paradigm, we outline a care delivery model that emphasizes an interdisciplinary approach in which the clinical neuropsychologist is a key participant. We discuss the importance of nonmedical, psychoeducational interventions introduced during the acute phase to facilitate recovery after sport-related concussion. Finally, using the local experience of our “Concussion Clinic” as a backdrop, we offer two separate case studies that demonstrate the value of this model in evaluating and managing athletes after sport-related concussion. The overall objective of this paper is to provide an adaptable template that neuropsychologists and other healthcare providers can use to improve the overall care of athletes with sport-related concussion and civilians with mild traumatic brain injury.

The present study used a synchronization-continuation paradigm during continuous bimanual drumming with different cues in 17 persons with Down syndrome, eight typical persons with similar mental age and eight typical persons with similar chronological age. The task required participants to hit two drums with their hands at the same time following music (e.g., a tune with various decibel drum beats), auditory (e.g., sound of drumbeat), verbal (e.g., voice saying “drum”), and visual (e.g., video of both hands moving up and down and hitting the drums together) cues for 10 seconds, then continue drumming in the absence of cues for another 10 seconds. In general, when all groups were following the music cues their movements were faster as compared with their movements in the auditory, verbal, and visual conditions. In addition, when following visual cues all groups produced more accurate and consistently coordinated movements than with the other cue types. Further, participants with Down syndrome often stopped moving when the pacing cues were eliminated indicating a need for continuous cues for continuous movements.

Ongoing debates about appropriate foci and growth of sport management research, application, theory, and training are evidence of the field’s growing pains. These growing pains also occur in other fields in which they function as a means to expand and elaborate the paradigms through which fields of inquiry grow and mature. In this study, a panel of 17 leading sport management scholars from around the globe responded to three iterations of a Delphi questionnaire probing their views about the status and future of the field. Panelists agreed that stronger research, additional cross-disciplinary research, a stronger link between theory and practice, enhanced infrastructure, and improved doctoral training are desirable objectives. They disagreed, however, about the appropriate academic home for sport management, what constitutes quality research, the roles of qualitative vs. quantitative research, and the relative value of basic vs. applied research. The results show that by actively engaging in debates over the issues identified in this study, sport management scholars can explore new ways of perceiving, thinking, and valuing that could enable proficient and constructive development of the field.
