“The body conforms and adapts to the intensities and directions it is habitually subjected to.”— Wolfe’s Law
In triathlon, training intensity – or how hard the effort is – is typically described by terms such as aerobic, sub-threshold, lactate threshold, VO2 and recovery. Training at different levels of intensity stimulates different training responses in the body. Training at higher intensities (typically performed as intervals) is an effective tool to maximize training time so that your training becomes more specific to your goal event while minimizing the risk of overtraining, burnout and injury.
This video with David Glover, MSE, MS, CSCS will help you better understand intensity while discussing four different ways to measure your intensity.
