Acute and chronic hydration status is important for athlete safety and performance and is frequently measured by sports scientists and performance staff in team environments via urinalysis. However, the time required for urine collection, staff testing, and reporting often delays immediate reporting and personalized nutrition insight in situations of acute hydration management before training or competition. Furthermore, the burdensome urine collection and testing process often renders chronic hydration monitoring sporadic or non-existent in real-world settings. An automated urinalysis device (InFlow) was developed to measure specific gravity, an index of hydration status, in real-time during urination. The device was strongly correlated to optical refractometry with a mean absolute error of 0.0029 (±0.0021). Our results show this device provides a novel and useful approach for real-time hydration status via urinalysis for male athletes in team environments with high testing frequency demands.

Coach, Data Analyst, and Protector: Exploring Data Practices of Collegiate Coaching Staff
A rapidly emerging research community at the intersection of sport and human-computer interaction (SportsHCI) explores how technology can support physically active humans, such as athletes. At highly competitive levels, coaching staff play a central role in the athlete experience by using data to enhance performance, reduce injuries, and foster team success. However, little is known about the practices and needs of these coaching staff. We conducted five focus groups with 17 collegiate coaching staff across three women’s teams and two men’s teams at an elite U.S. university. Our findings show that coaching staff selectively use data with the goal of balancing performance goals, athlete emotional well-being, and privacy. This paper contributes design recommendations to support coaching staff in operating across the data life cycle through gathering, sharing, deciding, acting, and assessing data as they aim to support team success and foster the well-being of student-athletes.

Data storytelling is the skill to communicate data effectively and efficiently. Effective data storytelling goes beyond data visualization and focuses on explanation with clear rhetorical functions. It starts with a set of data insights collected from the data science workflow and involves iterative and interactive processes of filtering those insights into story slices, from which data stories can be created through ordering, organizing and narration. Data storytelling is an integral component of a well-rounded data science education, which complements foundational skills like quantitative reasoning and programming. Despite its significance, solid understanding of the theory and practice of developing data storytelling competency is lacking. Data storytelling is often perceived as a mythical process where quantitative information magically transforms into compelling narratives. Designing scalable coaching tools for data storytelling requires leveraging multidisciplinary expertise from learning science, computer science, data science, communication science, and human-centered design. In this workshop, we will share some initial findings and reflections from our interdisciplinary team searching for effective coaching methods and tools to support coaching data storytelling at scale. We will present results from literature reviews and expert interviews which will be packaged into a set of foundational tools such as mental model, cognitive processes and schema for story construction, assessment strategy, as well as preliminary ideas of tools to support data storytelling coaching. We hope to use this workshop to build a community of researchers and practitioners in coaching data storytelling in postsecondary formal and informal learning context.more » « less

Wearable devices are ubiquitous and Internet of Things (IoT) devices have made it possible by connecting real-time devices to virtual cloud. There are also a tremendous number of IoT-enabled consumer products for various healthcare applications. Mostly, IoT devices are used for health monitoring systems, though other business and service communities are customizing the IoT technology for greater opportunity and long-term benefit. Wearable health devices have been used for better health monitoring and exchanging more data with the physician to get the guidance of treatment or earlier diagnostic. Health monitoring in athletes is one of the multifaceted applications of wearable IoT devices whereas these devices collect and store data on their performance and progression. This technology can protect athletes by detecting any adverse health problem that occurs during the training period or at the time of the game. In this paper, we investigate the real-time monitoring of physiological parameters of the athlete during game time and performance analysis from the stored data. Continuous health monitoring during game time and off-days will reduce sports-related risks,stress and injuries of an athlete even sometimes it can save them from life-risk fatal accidents. This research integrates an IoT-based framework to develop a stress index for athletes that can be used as an indicator for monitoring athlete’s health. The proposed framework helps in monitoring the variability of the sensor information for the long-term analysis.more » « less

Complex problems require complex teams comprised of individuals with different backgrounds, skills and perspectives to work effectively toward their solution. Increasingly, this is being accomplished through the creation of multi-team systems (MTS) that are developed and implemented in alignment with team science-based strategies. MTS are comprised of individual teams with their own goals that are interconnected and work collaboratively toward a larger, common goal. Attitudinal (cohesion, trust, commitment), behavioral (coordination, communication, shared leadership) and cognitive (situational awareness, shared mental models) competencies support MTS effectiveness. Multisector MTS are even more complex, as team members bring aspects of their organizational culture into the MTS, and if priorities and practices are not well aligned, team function and effectiveness can suffer. Thus, for multisector MTS to work, they must begin with a foundational understanding of the component parts, that is, each organization’s culture and priorities, and how – or if – they align for the success of the collaborative. We created a multisector MTS to develop and implement a project funded by the National Science Foundation’s (NSF’s) Scholarships in Science, Technology, Engineering and Mathematics (S-STEM) program. The project’s objectives are to: increase the number of domestic low-income academically talented students with demonstrated financial need obtaining master's degrees in supported disciplines and entering the US STEM workforce; implement and evaluate the impact of our Flexible Internship-Research-Education (FIRE) model, which integrates evidence-based strategies that provide student career and educational development support, on student success; and implement, study and disseminate an MTS model for multi -organizational collaboration toward career and educational development. The partners include four universities – three Carnegie R2 public Historically Black Colleges and Universities and one Carnegie R1 private, highly selective admissions institution – and a major government employer. Six teams comprise our MTS; with the exception of one, each team has representatives from each partner organization. We sought to understand how each organization’s culture influenced – or might potentially influence – team interactions. The guiding research question for this study is: In what ways – positive or negative – do partner organizations’ cultures impact team members’ engagement with the project? We were interested in gauging how organizational culture, operationalized by performance values (rewarding individual performance vs. team performance), communications (transparent vs. need-to-know, clarity, frequency), conflict resolution and collaborative vs. competitive environments, manifested in their engagement with the MTS. We also explored how – or if – their organization’s priorities aligned with the overall project’s aims and what specific areas might be sources of support and/or challenges as the teams progressed. We conducted open-ended structured interviews with eight project team members who each served on at least one of the six teams. We are completing both content and thematic analyses to understand how team members speak about their organizational influences and engagements within and among the teams. We are finding team members are adaptable; regardless of individual or organizational priorities, when challenges arise, they can re-center on the project’s aims and work collaboratively toward student success. We expect results will illuminate factors multisector MTS teams should consider when forming collaborations.more » « less

Resilient teams overcome sudden, dynamic changes by enacting rapid, adaptive responses that maintain system effectiveness. We analyzed two experiments on human-autonomy teams (HATs) operating a simulated remotely piloted aircraft system (RPAS) and correlated dynamical measures of resilience with measures of team performance. Across both experiments, HATs experienced automation and autonomy failures, using a Wizard of Oz paradigm. Team performance was measured in multiple ways, using a mission-level performance score, a target processing efficiency score, a failure overcome score, and a ground truth resilience score. Novel dynamical systems metrics of resilience measured the timing of system reorganization in response to failures across RPAS layers, including vehicle, controls, communications layers, and the system overall. Time to achieve extreme values of reorganization and novelty of reorganization were consistently correlated with target processing efficiency and ground truth resilience across both studies. Correlations with mission-level performance and the overcome score were apparent but less consistent. Across both studies, teams displayed greater system reorganization during failures compared to routine task conditions. The second experiment revealed differential effects of team training focused on coordination coaching and trust calibration. These results inform the measurement and training of resilience in HATs using objective, real-time resilience analysis.more » « less
