Unlocking Performance Gains: The Power of Personalized Training Zones with CHASKi

Understanding the science behind exercise testing and training intensity zones is key to optimizing performance for endurance athletes. At CHASKi, we emphasize the value of data-driven training based on ventilatory thresholds, and today we’ll explore why testing and threshold-based training are so impactful. We’ll also dive into a cyclist’s case study, showcasing how CHASKi helped …

Introduction to Breathwork for Endurance Athletes

Research suggests that controlled, deliberate breathing patterns can dramatically affect sports outcomes. For instance, specific breathing techniques have been shown to enhance endurance performance by improving oxygen utilization and delaying the onset of fatigue[1]. Other studies have documented how different breathing techniques can either enhance or impair athletic performance, depending on their application, underscoring the …

CHASKi Teams Up with UTC- ButcherBox Cycling p/b LOOK

As sports technology continues to advance, the integration of new tools into training is becoming crucial to optimize performance. The recent collaboration between CHASKi and UTC- ButcherBox Cycling, an elite cycling team, exemplifies this trend. This partnership introduces advanced respiratory monitoring technology to athletes’ training programs, aiming to refine how performance is tracked and improved. …

Could Respiratory Rate Serve as a Superior Indicator of Physical Effort?

Metrics like heart rate, speed, and power have long been the gold standard for monitoring physical effort during exercise. However, emerging research suggests that respiratory rate (RR) could be a more reliable and insightful marker of exercise intensity. As coaches and athletes seek the most effective ways to optimize training, understanding the role of respiratory …

Knowing When to Rest: How to Avoid Overtraining by Monitoring Recovery and Respiratory Rate

Proper rest and recovery are essential components of any successful training program. At CHASKi, we believe that understanding when to take a break can help athletes avoid the pitfalls of overtraining. This post explores the principles of recovery, the differences between overreaching and overtraining, and how respiratory rate (RR) can serve as an indicator of …

Estimate Your Maximal Lactate Steady State Using Ventilatory Thresholds

Understanding the maximal lactate steady state (MLSS) is crucial for endurance athletes, as it signifies the highest intensity one can sustain without causing significant intramuscular or blood pH imbalances. Essentially, MLSS is a key indicator for gauging endurance performance, reflecting the ability to maintain a high aerobic rate during prolonged exercise. Breakthrough Study: Ventilatory Thresholds …

CHASKi Running Validation Study: Preliminary Results

We recently conducted a preliminary study to further validate CHASKi’s technology against the gold standard on the treadmill. Similar to our cycling validation study, we are comparing CHASKi’s evaluation of ventilatory thresholds and respiratory frequency with ergospirometry. This study involved 14 volunteers of varying ages and sports disciplines. Our preliminary results show high agreement between CHASKi …

Training at altitude with CHASKi

The benefits of altitude training Altitude training is common practice among endurance athletes seeking to improve performance. It is generally performed at > 2,000 meters (> 6,560 ft) above sea level and induces a series of physiological adaptations, such as increased production of red blood cells and hemoglobin, which improve the body’s ability to transport and utilize oxygen. These adaptations generate improved …

Protocol for ventilatory threshold determination test

Our test is maximal and stepwise, starting with a 3-minute warm-up at 50 watts, then ramping up to 100 watts with 20 watt increments every 80 seconds until exhaustion. You can download this protocol for Zwift at the following link. To load it in your Zwift session, you must access in your computer to Documents/Zwift/Workouts/###### …
