Conceptualizing the adventure-sports coach

As a comparatively recent development, the adventure-sports coach struggles for a clear and distinct identity. The generic term ‘instructor’ no longer characterizes the role and function of this subgroup of outdoor professionals. Indeed, although the fields of adventure/outdoor education and leadership are comparatively well researched, the arrival of this ‘new kid on the block’ appears to challenge both the adventure-sports old guard and traditional views of sports coaching. In an attempt to offer clarity and stimulate debate, this paper attempts to conceptualize the adventure-sports coach in the context of the existing roles in the field and current motivations for activity in the outdoors. We identify issues that are specific to the adventure-sports coach while also recognizing those skills and competencies shared with other professionals, both in the adventure sports profession and traditional sports coaching fields. Based on this review, we offer a conceptual model which may be used to focus debate, stimulate research and, at a possible later stage, to underpin accreditation, training and professional development

Professional judgement and decision-making in the planning process of high-level adventure sports coaching practice

This investigation examined the planning and decision-making processes in adventure sports coaching. We utilised a thematic analysis approach to investigate the planning decision-making practices of a sample of high-level adventure sports coaches over a series of sessions. The investigation discovered that, in planning coaching activity, high-level adventure sports coaches draw on their epistemological values and domain-specific expertise, employ a synergy of classic and naturalistic decision-making processes, and continually audit the evolving coaching process. Based on these findings, implications for professional training, accreditation and development of adventure sports coaches are presented

Managing the Cognitive Loads Associated with Judgment and Decision-Making in a Group of Adventure Sports Coaches: A Mixed-Method Investigation

This paper expands work on professional judgment and decision-making and examines the coping strategies used by adventure sports professionals to manage the cognitive loads of decision-making. Amixed methodology was employed in which asample of participants completed aPro Active Coping Inventory and asub-group then completed an Applied Cognitive Task Analysis of atypical coaching scenario. The study determines that the participants manage their cognitive load utilising arange of heuristics, avoidance strategies and instrumental support that. includes their communities of practice, anticipation of acute cognitive loads and the development of adaptable plans based on anticipated environmental conditions and client abilities. That plan is modified in response to the actual conditions and client abilities as observed. These strategies reduce the depletion of the coaches’ own cognitive resources by managing the demands. We conclude that the professionals are aware of their cognitive resources and manage its expenditure

Rickettsia rickettsii Infection of Human Macrovascular and Microvascular Endothelial Cells Reveals Activation of Both Common and Cell Type-Specific Host Response Mechanisms▿

Although inflammation and altered barrier functions of the vasculature, due predominantly to the infection of endothelial cell lining of small and medium-sized blood vessels, represent salient pathological features of human rickettsioses, the interactions between pathogenic rickettsiae and microvascular endothelial cells remain poorly understood. We have investigated the activation of nuclear transcription factor-kappa B (NF-κB) and p38 mitogen-activated protein (MAP) kinase, expression of heme oxygenase 1 (HO-1) and cyclooxygenase 2 (COX-2), and secretion of chemokines and prostaglandins after Rickettsia rickettsii infection of human cerebral, dermal, and pulmonary microvascular endothelial cells in comparison with pulmonary artery cells of macrovascular origin. NF-κB and p38 kinase activation and increased HO-1 mRNA expression were clearly evident in all cell types, along with relatively similar susceptibility to R. rickettsii infection in vitro but considerable variations in the intensities/kinetics of the aforementioned host responses. As expected, the overall activation profiles of macrovascular endothelial cells derived from human pulmonary artery and umbilical vein were nearly identical. Interestingly, cerebral endothelial cells displayed a marked refractoriness in chemokine production and secretion, while all other cell types secreted various levels of interleukin-8 (IL-8) and monocyte chemoattractant protein 1 (MCP-1) in response to infection. A unique feature of all microvascular endothelial cells was the lack of induced COX-2 expression and resultant inability to secrete prostaglandin E2 after R. rickettsii infection. Comparative evaluation thus yields the first experimental evidence for the activation of both common and unique cell type-specific host response mechanisms in macrovascular and microvascular endothelial cells infected with R. rickettsii, a prototypical species known to cause Rocky Mountain spotted fever in humans
