Problem
Traditional methods of assessing aerobic performance and determining ventilatory thresholds require lab equipment and trained personnel, making it difficult for athletes to personalize training plans and optimize performance outside of controlled settings. This limits access to key performance metrics that can inform training intensity and prevent overtraining.
Solution
CHASKi offers a wearable respiratory monitoring system that provides athletes with real-time, lab-level metrics to assess their aerobic performance during training. The lightweight and portable device measures ventilatory thresholds, allowing users to individualize training plans and optimize training time. By visualizing performance metrics in real time, athletes can proactively adjust intensity during workouts. The system also enables users to analyze training data to benchmark and track physiological adaptations, quantifying the training response and ensuring workouts align with specific goals.
Target Audience
The primary target audience includes endurance athletes (runners, cyclists, triathletes), coaches, and sports healthcare professionals seeking to optimize training and performance through personalized respiratory monitoring.
