These constants were developed based on the experimentally observed relationship between heart rate and lactate level. For men this will give a TRIMP value of 0 to 4.37 per minute and for women 0 to 3.4.
==Worked Example==
A worked example would be a male athlete with a HR<sub>max</sub>=200 and HR<sub>rest</sub>=40 training for 30 min. at 130 BPM. The TRIMP<subsup>exp</subsup> is therefore TRIMP<subsup>exp</subsup> = 30 x (130-40)/(200-40) x 0.64e<sup>(1.92x(130-40)/(200-40))</sup>
Which simplifies to
TRIMP<subsup>exp</subsup> = 30 x 0.56 x 0.64e<sup>(1.92x0.56)</sup>
Which is a value of 32. This is obviously a simplified example as in reality an athlete heart rate will vary over time. To implement this algorithm requires a software package with access to the records of the heart rate. Thankfully modern [[Heart Rate Monitor]]s makes this relatively trivial.
