My work explores how the precise manipulation of interval intensity, duration, and recovery can optimize cardiovascular, metabolic, and neuromuscular adaptations. These frameworks are now used by coaches and high-performance teams around the world to integrate HIIT into sport-specific training cycles with measurable results.

My research has helped redefine what’s possible for highly trained endurance athletes. I’ve shown that improvements in VO₂max and competitive performance can be achieved through targeted interval work—not just by increasing training volume. I also promote use of Anaerobic Speed/Power Reserve concept, a breakthrough method for personalizing training based on individual athlete profiling.

By integrating environmental and physiological stressors into performance models, I’ve worked to advance our understanding of how heat, climate, and other external factors interact with training and nutrition. This work has helped guide teams in adapting to challenging environments—crucial for events ranging from desert ultramarathons to Olympic triathlons.

As lead investigator in multiple clinical trials, I’ve explored the interaction between diet and exercise, with a focus on very low-carbohydrate, high-fat (VLCHF) diets. My findings show that VLCHF nutrition—on its own or combined with HIIT—can significantly reduce visceral fat, alter fuel utilization, and preserve high-intensity capacity. These results have influenced athlete nutrition strategies from grassroots programs all the way to the Olympic level.
