  • I’ve Seen This, So I’ve Got This! Exploring the Use of Imagery and
           Self-Talk Within Action Sports Athletes

    • Authors: Patrick R. Young
      Abstract: The present study aimed to expand the current knowledge of psychological skills usage within athletes of action sports by exploring the use of imagery and self-talk within skateboarders and snowboarders. Skateboarders and snowboarders (N 5 74) completed the Athletic Coping Skills Inventory (ACSI-28; Smith et al., 1995), the Self-Talk Questionnaire (S-TQ) for sports (Zervas et al., 2007), and the Sport Imagery Questionnaire (SIQ; Hall et al., 1998). Results indicated that participants scored significantly higher than reported norms of traditional athletes (Smith et al., 1995) on the coping with adversity and goal-setting/mental preparation subscales of the ACSI-28, and to a similar degree to traditional athletes on the remaining subscales. However, participants scored significantly lower on the total score of the ACSI-28 than previously reported action sports athletes (Young & Knight, 2014). Participants scored significantly higher than reported norms of traditional athletes on the cognitive functional and motivational functional subscales of the S-TQ. On the SIQ, participants scored significantly lower than reported norms for traditional athletes (Hall et al., 2005) on the MG-M subscale, while scoring similarly to reported norms on the CG, CS, MS, and MG-A subscales. Results of the present study confirm that action sports athletes utilize psychological skills to a degree similar to that of traditional athletes, and that skateboarders and snowboarders specifically include the use of imagery and self-talk within their psychological skills arsenal.

  • Rim-to-Rim Wearables at the Canyon for Health (R2R WATCH): Physiological,
           Cognitive, and Biological Markers of Performance Decline in an Extreme

    • Authors: Kristin Divis et al.
      Abstract: Success in extreme environments comes with a cost of subtle performance decrements that if not mitigated properly can lead to lifethreatening consequences. Identification and prediction of performance decline could alleviate deleterious consequences and enhance success in challenging and high-risk operations. The Rim-to-Rim Wearables at the Canyon for Health (R2R WATCH) project was designed to examine the cognitive, physiological, and biological markers of performance decline in the extreme environment of the Grand Canyon Rim-to-Rim (R2R) hike. The study utilized commercial off-the-shelf cognitive and physiological monitoring techniques, along with subjective self-assessments and hematologic measurements to determine subject performance and changes across the hike. The multiyear effort collected these multiple data streams in parallel on a large sample of participants hiking the R2R, leading to a rich and complex data set. This article describes the methodology and its evolution as devices and measurements were assessed after each data collection event. It also highlights a subset of the patterns of results found across the data streams. Subsequent work will draw on this data set to focus on building more sophisticated, predictive statistical models and dive deeper into specific analyses (such as the physiological and biological profiles of hikers who were left behind by their hiking partners).

  • Walking on Thin Ice: Exploring Demands and Means of Coping During an
           Extreme Expedition

    • Authors: Tracey J. Devonport et al.
      Abstract: The present exploratory study was undertaken with two experienced explorers in order to examine daily events, perceived demands, coping strategies, and mood during a unique 636–675 km ‘‘double solo’’ crossing of Lake Baikal, a frozen lake in Siberia. A 59-year-old female explorer and a 49-year-old male explorer completed a daily survey and written diary during the expedition to collect situational data. Two semi-structured interviews were also completed, one within 24 hours and a second within four months of their return. These interviews sought to identify demands and coping efforts perceived as being most pertinent during their expedition. Guided by the work of Skinner et al. (2003), families of coping were organized around three human concerns (autonomy, relatedness, and competence) and two targets of coping (self or context). Findings illustrate two very different expedition experiences as evidenced by demands faced and coping strategies utilized, which influenced perceptions of workload and emotions experienced. Each explorer brought idiosyncrasies, which, when combined with different expedition experiences, bore influence on coping behaviors (focused on the self or context) and outcomes relative to the concerns of autonomy, relatedness, and competency. In discussing the findings, recommendations are offered for those preparing to undertake expeditions in extreme environments.

  • The Effects of Energy Intake on Upper Respiratory Symptoms in
           Ultra-Endurance Triathletes

    • Authors: Yasuki Sekiguchi et al.
      Abstract: Background: It is unclear whether energy intake can impact the incidence of upper respiratory symptoms (URS). The purpose of this study was to examine if there are differences in energy intake between symptomatic (SYM) and asymptomatic (ASYM) groups of URS in Ironman-triathletes. Methods: Thirty-three subjects competing in the Lake Placid Ironman-triathlon (mean±SD; age,37±8y; height,178±8cm; mass,76.3±10.4kg; body fat,10.8±3.8%) were randomized into either the control (CON) or intervention (INT). INT consumed 4-commercial recovery drinks, two immediately post-race and two 3-hours post-race. Calorie and macronutrient intake were recorded pre-, during, and post-race. Subjects completed the Wisconsin URS Survey to assess URS over the next two weeks. Two analyses were done by comparing results between CON and INT, and when subjects were classified as either asymptomatic (ASYM=20) or symptomatic (SYM=13). Results: There were no differences in energy intake (p>0.05) and URS (INT,32±38; CON,16±23; p=0.155). However, on the race day, SYM (9,044±2,598kcal) consumed less energy intake than ASYM (10,991±2497kcal) (p=0.044). Also, SYM consumed less energy the day before the race (p=0.031) and post-race (p=0.008). ASYM consumed greater carbohydrate the day before the race (p=0.032), fat the day of the race (p=0.006), carbohydrate post-race (p=0.08) and fat post-race (p=0.002). Conclusions: Overall energy intake was similar between CON and INT. However, when subjects were differentiated by URS, SYM consumed less calories the day before and day of the race versus ASYM.

  • Errors of Measurement for Blood Parameters and Physiological and
           Performance Measures After the Decay of Short-Term Heat Acclimation

    • Authors: Andrew T. Garrett et al.
      Abstract: Introduction: It is important to determine the accuracy of measurements relative to potential treatment effects, with time intervals between tests. Purpose: The aim of this study was to assess the error of measurement for blood parameters, physiological, and performance measures after the decay of short-term heat acclimation. Methods: Ten trained males (Mean±SD: age 28±7 y; body mass 74.6±4.4 kg; 4.26±0.37 L.min-1; peak power output (PPO) 329±42 W) completed an exercising heat stress test (HST) at baseline, 2nd day after acclimation and then during decay at 1, 2, 3 and 5-6 wks. CoV (95% CI), SE (95% CI) and Pearsons (r) were used for analysis of blood volume (blood, plasma, red cell volume, mean hemoglogin mass); plasma (aldosterone, arginine vasopressin [AVP], total protein, albumin, sodium); physiological (rectal temperature, cardiac frequency) and performance (exercise performance capacity, PPO). Results: The CoV (95% CI), SE (95% CI) and r with a 1-wk interval for blood volume was 2.3% (1.6 to 4.3; 1.9 [1.3 to 3.4 mL.Kg-1]; r=0.93; n=10). After 2-wk and 5-6 wks this had increased to 4.9% (3.4 to 9.3; 3.8 [2.6 to 7.0 mL.Kg-1]; r=0.76; n=9) and 5.5% (3.6 to 12.8; 4.5 [2.9 to 10.0 mL.Kg-1]; r=0.65; n=7) respectively. Conclusions: Blood volume and physiological measures demonstrated the least error one week apart but increased thereafter. Plasma concentrations and performance markers had the greatest error with repeat measures after one week. Therefore, for greater reliability and low measurement error measures should be taken no more than one week a part in repeated experimentation.

  • Effectiveness of Short-Term Heat Acclimation on Intermittent Sprint
           Performance in the Heat with Moderately Trained Males

    • Authors: Andrew T. Garrett et al.
      Abstract: Purpose: Effectiveness of short-term heat acclimation (STHA), over 5-days (permissive dehydration), on intermittent heat stress test (HST) with males. Methods: Ten, moderately-trained, males (mean [SD]; age 25.6 [8.9] y; stature 180.7 [5.6] cm; body mass 83.2 [10.8] kg; and 45.3 [6.5] participated. The HST was 9 x 5min (45-min) of intermittent exercise based on professional soccer players. One week apart, HST1 vs HST (11.0°C; 50%RH), as a reliability trial and HST3 in 31.0°C; 50%RH were completed. Then 90 min dehydration, STHA (no fluid intake), for 5 consecutive days (39.5oC; 60%RH), using controlled-hyperthermia (~rectal temperature [Tre] 38.5oC). The HST4 within one week after STHA. Blood plasma constituents: percent plasma volume (%PV), aldosterone, total protein, albumin, electrolytes, cortisol and HSP70. Data analysis reported as mean differences with 95% confidence intervals (95%CI) and Cohen’s d effect size. Results: Post STHA, there was a decrease of -0.20 Tre at 45-min in the HST (95%CI -0.40 to -0.05°C; P=0.03; d =-0.56); mean skin temperature (-0.80; -1.30 to -0.30°C; P=0.007; d =-1.46) and mean body temperature (-0.30; -0.50 to -0.10°C, P=0.01; d =-0.75). Cardiac frequency reduced (-3: -5 to -1 b.min-1; P=0.01; d =-0.20) and %PV increased (7.3: 0.9 to 13.7%; P=0.03; d=0.59). Mean Peak Power (MPO) increased (Pd =0.63). Conclusions: Short-term heat acclimation (5-days) with dehydration, using controlled-hyperthermia technique, is effective for physiological adaptations during intermittent exercise in the heat, with moderately trained males.

  • Influence of Core Temperature on Psychomotor Performance during Cold
           Weather Military Training

    • Authors: Douglas Jones et al.
      Abstract: Purpose: Cold environments may deteriorate psychomotor performance due to slowing of neuronal signals, distractions caused by pain and discomfort, and a loss of manual dexterity. The extent to which core temperature (Tc) influences psychomotor performance in the cold has not been established. Therefore, psychomotor performance and Tc were assessed during a cold weather military training exercise to evaluate this relationship.Methods: Thirty-six military personnel (age: 26 ± 4 yr, ht: 175 ± 8 cm, wt: 79.1 ± 11.1 kg) participating in cold weather training volunteered for this study. Participants completed a 10-min immersion in cold (1°C) water, followed by 60 min of rewarming. Physiological, perceptual, and psychomotor assessments were made throughout the training. For analysis, participants were divided into groups based on their lowest achieved core temperature (< 35.0°C = HYP; 35.0-36.0°C = CS-M;> 36.0°C = CS-S). Psychomotor performance was then compared among the groups to determine the influence of Tc on performance.Results: Although cold water immersion deteriorated performance, no differences were observed among the three groups at any time point during the training for simple reaction time (HYP: 298 ± 49 ms; CS-M: 313 ± 55 ms; CS-S: 326 ± 53ms; p = 0.677).Conclusion: Findings suggest that cold water immersion deteriorates psychomotor performance which, even in the presence of mild hypothermia, is not directly influenced by Tc. Additional observations reveal large variations in Tc among a homogenous group in response to cold water immersion.

  • Cognitive Offloading Strategies and Decrements in Learning: Lessons from
           Aviation and Aerospace Crises

    • Authors: D. Christopher Kayes et al.
      Abstract: Examples from aviation and aerospace illustrate the potential consequences that emerge when organizations replace learning from experience with technology, a process referred to as a cognitive offloading strategy (COS). Examples include the Air France Flight 447 crash involving an Airbus 330-203 and the Lion Air Flight 610 crash involving a Boeing 737 Max. From the perspective of human performance in extreme environments, COS represents an underexplored source of organizational vulnerability which presents a particular challenge for learning in organizations. Decrements in learning result from COS because COS creates gaps in procedural knowledge and deprives operators of opportunities to learn in the face of event-induced stress. Due to the inevitability of COS in extreme environments, recommendations for building resilience include offering training scenarios that support the development of a positive stress response, facilitating the ability to learn in the face of uncertainty, and supporting highly engaged experiential learning to build procedural (and often tacit) knowledge of operations.

  • Walking on ‘‘Mars’’: Gendered Group Processes in
           Space Analog Missions

    • Authors: Inga Popovaite et al.
      Abstract: Most research on mixed-gender teams in space analog environments focuses on individual-level variation and overlooks structural causes of inequality. Status characteristics theory posits how socially recognized traits, such as gender, contribute to the formation of informal hierarchies by denoting perceived levels of competence to group members. We investigated gender as a status characteristic in groups in space analog environments. We used data from the Mars Desert Research Station (MDRS) and hypothesized that women crew members are less likely than men to be selected to participate in simulated extravehicular activities during a Mars simulation at the MDRS. We used reports and biographies from 30 randomly selected crews (n = 177) posted on the MDRS website to construct our dataset and multilevel generalized regression models to test our hypothesis. Women crew members were 6% less likely to participate in simulated extravehicular activities than men, controlling for crew role, education, and other factors. Our study shows that gender acts as a status characteristic and influences group decisions in crews in space analogs. These results highlight the need for more studies on interactional inequalities in preparation for a long-term human spaceflight.

  • Outdoor Adventure Practice in Kenya: Injuries, Illnesses, Non-Medical
           Concerns, and Evacuation Profiles on Mt. Kenya

    • Authors: Lucy Joy Wachira et al.
      Abstract: Background: Outdoor adventure is inevitably linked to risks that lead to injuries, psychological distress, illnesses, and even fatalities. Gathering detailed information on such occurrences and their contributing factors is a valuable component of risk management in outdoor programs. This study investigated the occurrence of injuries, illnesses, evacuation profiles, non-medical concerns, and near-miss events in outdoor adventure practice in Kenya.Methods: A mixed-methods approach involving quantitative and qualitative methods was used to collect data from 136 outdoor adventure practitioners in Kenya. Questionnaires, key informant interviews, focus group discussions, and desk reviews were employed to collect data.Results: The majority of injuries and illnesses occur during mountaineering (39%) and hiking and navigation (25.7%) events. The most reported incidents were mountain sickness (25%) and musculoskeletal injuries consisting of fractures (30%), cuts and wounds (14.7%), blisters (12.5%), sprains and dislocations (12.5%), and muscle strains and pulls (8.8%). Out of the 128 reported evacuation incidences on Mt. Kenya, 95 were due to mountain sickness and10 due to falls. Combined age and sex of the climbers and the location/altitude on the mountain are predictors of the occurrence and the type of injury/illness on the mountain (x2 (10, n = 128) = 63.32, P < 0.001). However, only altitude significantly contributes to the model (P < 0.001). Reported near-miss incidences included flash floods, aggressive encounter with wildlife, getting lost for extended period, near falls and slips, and rolling-rock falls. Non-medical concerns reported included extreme anxiety, intoxication from drug and alcohol use, confrontation and fights, and disorientation.Conclusions: There is evident incidence of injuries and illnesses of varying severity, with age, sex, and altitude reached being key predicting factors. Mitigating efforts and preventive measures should be employed as well as risk assessment and management to promote safety. The findings are vital to advise policy and practice and enhance awareness among practitioners and interested parties in Kenya and also in other destinations with similar conditions, terrains, and challenges.

  • A Review of the Effects of Dietary Restriction, Dehydration, and Caffeine
           Withdrawal on Cognition: Implications for a Disabled Submarine Scenario

    • Authors: Sarah Chabal
      Abstract: In the event that submariners become trapped aboard a disabled submarine (DISSUB), they must perform a multitude of cognitively demanding tasks in order to maximize their likelihood of survival. During this time, submariners will also be forced to endure poor living conditions, including drastic changes to their nutrition. These nutritional changes have the potential to impair submariners’ cognitive functioning and affect operational performance, which could jeopardize survival; however, the effects of DISSUB nutrition on cognitive performance are not well understood. This review first describes the unique nutritional conditions that submariners will experience in a DISSUB scenario, including the change to a high-fat/low-calorie diet, restricted water availability, and cessation of caffeine consumption. The known effects of diet (including a high-fat diet and caloric restriction), dehydration, and caffeine withdrawal on cognition are then separately reviewed, with a discussion of how these effects may impact survivability in a DISSUB scenario.

  • Sources of Nutrition Information in Recreational Ultra-marathon Runners: A
           Mixed Methods Analysis

    • Authors: Sara E. Mahoney et al.
      Abstract: Ultra-marathon events (i.e., .42.2-km) continue to grow in popularity; however, little is known regarding the sources of nutrition information which inform their beliefs and habits. The objective of this study was to characterize the acquisition of sport-specific nutrition information among ultra-endurance athletes using a mixed methods design. Qualitative data were collected through focus groups and analyzed using thematic analysis. Three primary higher order themes were identified: Optimal Diet for Ultra-Endurance Athletes, Common Sources of Information, and Barriers to Scientific Information. Then, a self-report inventory (Sources of Nutrition Information-SONI questionnaire) was developed to assess common sources of nutrition information and characterize their beliefs about those sources. Likert-type questions were used, and primary sources were scored out of 3, sub-questions out of 5. Differences between sources were assessed using RM-ANOVA. Participants (N = 224) accessed, responded to, and submitted the survey via a secure, study-specific web-based link. Peer reviewed literature was reported as the most frequently used (mean score = 1.64, p < 0.001), credible (3.02, p < 0.001), and interesting (2.62, p < 0.002). Social media was the most accessible (2.81, p < 0.001), but the least credible (1.87, p < 0.001). While social media was perceived less credible than other sources, its accessibility could make it a promising tool to provide evidence-based nutrition information to this population.
