Mean rating of perceived exertion
and affect during the 60-60 s and the 30-30 s LV-HIIT protocols.
1988, Physiological and psychophysical factors in the rating of perceived exertion
during uphill overland and treadmill running.
Abbreviations: ANOVA = analysis of variance, [BLa.sup.-] = blood lactate concentration, CVD = cardiovascular disease, FES = functional electrical stimulation, HC = handcycling, HPA = hypothalamic-pituitary-adrenal, HR = heart rate, HYB = hybrid exercise, IL = interleukin, IL-1ra = interleukin-1 receptor antagonist, PO = power output, [PO.sub.peak] = peak aerobic power, post+1 = 1 h postexercise, post+2 = 2 h postexercise, RER = respiratory exchange ratio, RPE = rating of perceived exertion

In addition, heart rate, core body temperature, oxygen uptake and Rating of Perceived Exertion
(RPE) were not significantly different throughout the exercise bout during the caffeine trial compared to placebo.
Effort perception was assessed using the 15-point (6-20) Rating of Perceived Exertion
(RPE) scale (Borg, 1998).
Exercise intensity was self-selected (3-4 on a 10-point Rating of Perceived Exertion
As already mentioned, don't go by heart rate, as this guideline is outdated; go by perceived exertion, according to the following, known as the Borg Rating of Perceived Exertion
Then give it a number, from 6 for "no exertion," to 20 equaling "maximal effort," based on the Borg Rating of Perceived Exertion
Ten healthy and moderately trained women (mean [+ or -] SD: age 27 [+ or -] 3.4 years, height 167.8 [+ or -] 4.6 cm, body mass 55.7 [+ or -] 4.7 kg, body mass index 19.8 [+ or -] 1.6, V[O.sub.2]max 44.4 [+ or -] 6.1 mL x [kg.sup.-1] x [min.sup.-1]) performed an incremental treadmill test to determine V[O.sub.2]peak, V[O.sub.2]-heart rate (HR), and rating of perceived exertion
Rating of perceived exertion
(RPE) and pain were measured with Borg's CR-10 scale (Borg, 1998).
During each work bout, oxygen consumption, heart rate, rectal temperature and rating of perceived exertion
(RPE) were continuously monitored.
Active rest is defined as slow, continuous movement (rating of perceived exertion
1 of 10 on the Borg scale) using the same muscle groups involved in the preceding aerobic activity.
