Running Talk Test
The running talk test can be applied as a monitor of running exercise intensity, Dr Matt long explores.
Nature has blessed us with five senses, one of which - the ability to talk, is an excellent way of self-regulating the intensity of your training activity as an athlete. Traditionally, the talk test has remained almost the exclusive preserve of the endurance athlete, but it is of use both for the middle-distance athlete and the sprinter too.
As athletes, we may use one, two, or all three energy systems, namely the Alactic, Lactate, and Aerobic. The alactic system predominates in the shortest of the sprints, the lactate system for longer sprints and middle distance running, and the aerobic system for endurance athletes.
The talk test and endurance running
Research conducted in 2011 at the Robert Kertzer Exercise Physiology Laboratory, University of New Hampshire, confirmed that the subjective measure of the talk test might give the endurance runner an indication of when their lactate threshold is being approached, meaning if this intensity is maintained, the duration of the activity is limited. When athletes show a rapid increase in levels of blood lactate, the Onset of Blood Lactate Accumulation (OBLA) occurs. At this critical point, the balance between lactate addition to and removal from the blood is disturbed. When predominantly utilising the aerobic energy system during an endurance run, the maximal lactate steady state (MaxLass or MLSS) is a level of exertion which if exceeded will result in a switch to the predominant utilisation of the lactate energy system, which cannot be sustained effectively for more than two to three minutes.
As well as delaying using the lactate system, there are training sessions when the endurance athlete will wish to almost exclusively use the aerobic energy system, such as the proverbial long steady Sunday morning run, or the shorter recovery run the day after a competition. According to Hanc (2004), the talk test is a reliable intensity gauge for keeping within the optimal aerobic zone, which is thought to be between 65-80% of maximum heart rate.
If you can chat to someone in whole sentences, your aerobic energy system is predominating, as your body is working at an intensity where there is sufficient oxygen to produce the required energy while also being used to talk. However, as the intensity increases the oxygen demand of the muscles increases meaning that there is less and less oxygen available to be used in the process of talking.
