Understanding the Training Experiences of Competitive Skiers with Tetraplegia

Research Background and Issues

• Identified Problems or Challenges: The authors point out that while "Adaptive Sports" play a significant role in improving the psychological health and quality of life for individuals with tetraplegia, research on technologies to enhance the competitive performance of these athletes is extremely limited. Moreover, compared to accessibility technologies and recreational adaptive sports, there is a relative lack of research on the technological needs of individuals with disabilities participating in competitive sports. Current adaptive skiing technologies, such as TetraSki, primarily focus on enabling basic skiing operations rather than improving training and competition performance.

• Why It Matters: In the field of sports, measuring and optimizing athletic performance is crucial for enhancing competitive levels and self-efficacy. However, due to physical limitations and equipment constraints, tetraplegic athletes find it challenging to use self-tracking technologies to improve their techniques in the same way non-adaptive athletes can. Furthermore, for this group, participating in competitive sports significantly enhances their sense of self-worth, social engagement, and independence, making this research critically important.

• Research Motivation and Related Work: Motivated by addressing health equity issues and promoting equal participation of individuals with disabilities in competitive sports, the authors explore technological improvements to TetraSki (adaptive skiing equipment) and its potential to enhance athletic performance. While earlier research focused on achieving accessibility in adaptive sports, few studies have explored how to optimize competitive training for athletes, which is the key contribution of this paper.

Solution

• Proposed Methods or Solutions: To address the research questions, the authors conducted semi-structured interviews with six TetraSki athletes and four coaches to gain insights into their current practices, challenges faced during training and competitions, and their expectations for technological support. Additionally, the authors explored how technologies such as real-time notifications, self-tracking, and data analysis could help improve athletic performance.

• Innovative Aspects: A notable innovation of this study is its focus on how technology can support athletes with severe functional limitations in extreme adaptive sports (e.g., skiing competitions), whereas prior research has typically concentrated on basic accessibility and recreational sports. Furthermore, the study emphasizes that technology should not merely serve as an assistive tool but also act as a mechanism to enhance athletic performance, self-efficacy, and collaboration between athletes and coaches.

• Implementation Steps and Key Technologies:

  1. Semi-structured interviews: Conduct interviews with athletes and coaches to understand current training practices and technological needs.
  2. Problem synthesis and technology ideation: Analyze interview data and design specific goals, including:
     • Real-time speed correction notifications (e.g., auditory or visual feedback).
     • Instant feedback mechanisms for improving turning techniques.
     • Tracking joystick data and skiing trajectory feedback.
     • Enhanced communication tools between athletes and coaches.
     • Adaptive analysis and playback tools to convert post-competition data into actionable improvement suggestions.
  3. Propose chairable interaction technologies and specific technical prototypes.

Research Outcomes

• Specific Findings: This study reveals that TetraSki athletes primarily rely on intuition, memory, and immediate feedback from coaches to adjust their performance during training and competitions, which significantly limits their independence. Although athletes express strong interest in recording and analyzing their competition performance, existing technologies and equipment lack accessible real-time data tracking tools and playback analysis capabilities.

• Advantages Over Existing Solutions:

  1. This study extends the scope of adaptive sports technology exploration from basic recreational activities to competitive training and performance optimization.
  2. The proposed solutions emphasize balancing independence with safety, enhancing athletes' self-efficacy and confidence rather than increasing their reliance on equipment or coaches.
  3. Unlike traditional shared control methods, this study designs innovative approaches for bidirectional communication between athletes and coaches (e.g., real-time light prompts, voice channels, and visualized data feedback).

• Experimental or Evaluation Results: Although this study primarily relies on qualitative interviews and user needs analysis, the authors identify a series of potential technological design directions:

  • Real-time speed and turning corrections.
  • Enhanced decision-making support during competitions through vibration or light prompts.
  • Automated post-competition video review and comprehensive data analysis generation.
  • Visualized or tactile assistive modes tailored for adaptive skiing.

• Limitations and Future Directions:

  1. The sample size is small, including only six athletes and four coaches, and does not cover users of "sip-and-puff" controllers.
  2. Specific evaluations of self-tracking technologies have not been conducted, and the proposed technologies require practical validation of their usability and effectiveness.
  3. Future research could explore broader athletic groups (e.g., other extreme adaptive sports) and the needs of users with different types of disabilities.

Through this study, the authors not only highlight the urgent needs of tetraplegic athletes in training but also propose specific and forward-looking technological intervention directions, contributing to a more comprehensive exploration of the potential for adaptive sports technology design within the field of human-computer interaction.
