Is the traditional approach to managing lactate threshold for better road race performance by solely focusing on increasing LT power output through high-intensity interval training and tempo rides still the most effective method, or should we be considering a more nuanced approach that incorporates specific training protocols targeting the underlying physiological mechanisms that contribute to LT, such as increasing mitochondrial density and enhancing muscle buffering capacity, and if so, what specific training protocols and intensities would be most effective in eliciting these adaptations, and how would these protocols be best integrated into a periodized training plan to maximize LT improvements and overall road race performance?
