This study examined the association of blood lactate concentration [La] and heart rate (HR) with ratings of perceived exertion (RPE) during 60 min of steady workload cycling. Physically active college-aged subjects (n=14) completed an exhaustive cycling test to determine VO2peak and lactate threshold (2.5 mmol l−1). Subjects then cycled for 60 min at the power output associated with 2.5 mmol l−1 [LA]. HR, [LA], RPE-overall, RPE-legs and RPE-chest were recorded at 5, 10, 20, 30, 40, 50 and 60… 

RPE association with lactate and heart rate during high-intensity interval cycling.

RPE during intervals of intense cycling were more sensitive to acute metabolic demand (evidenced by HR) versus [La]; tighter overall coupling of HR with RPE (vs [La] with R PE) and a dissociation between RPE-[La] suggest RPE were moresensitive to acute metabolism demand.

Blood lactate and heat stress during training in rowers.

This study suggests that high body temperature may constitute a significant factor of perceived exertion and disrupt indoor training session, and capacity to perform an endurance training on a rowing ergometer was improved by increasing air convection.

Session RPE following interval and constant-resistance cycling in hot and cool environments.

Under the conditions of this study, S-RPE is similar to acute RPE in that no single mediator seems universally dominant, and heat gain, circulatory adjustment to temperature regulation (HR), and [La] consequent to interval (INT) and constant-load (CON) cycling on session RPE (S-R PE).

Heart rate-based lactate minimum test: a reproducible method

The LMT using a heart rate-based protocol is a reproducible method of assessing HR at an exercise intensity where an equilibrium exists between blood lactate accumulation and elimination.

Differences between Males and Females in Determining Exercise Intensity.

Traditional exercise intensity markers are different between males and females and BL and %PO appear to be markers that might be used independently of sex.

Clinical Markers of Exercise Intensity as a Surrogate for Blood Lactate Levels Only During Low-Intensity Exercise in Patients With Coronary Artery Disease

HR and RPE should not be used as a surrogate to a La-based descriptor of exercise intensity in patients with coronary artery disease exercising at high intensity, due to the direct relationship between these variables that occur during the increasing exercise intensity.

Effect of Progressive Fatigue on Session RPE

Results support the hypothesis that sRPE is a sensitive tool that provides information on accumulated fatigue, in addition to training intensity, and exercise scientists without access to HLa measurements may now be able to gain insights into accumulated fatigue during periods of increased training by using sR PE.

Determination of Blood Lactate Training Zone Boundaries With Rating of Perceived Exertion in Runners

RPE values at the BLC training zone boundaries of 4.3 and 6.5 can be used as an affordable tool for controlling intensity to maintain the athletes in prescribed zones during training sessions.

Physiologic responses of older recreational alpine skiers to different skiing modes

The results suggest that aerobic metabolism predominates on flat and low intensity steep slopes and transitions to anaerobic metabolism on steeper high intensity runs.

The results indicated that the PWC(RPE) was not significantly different from RCP, and these thresholds may be associated with the same mechanisms of fatigue, such as increased levels of interstitial and arterial levels.



The validity of regulating blood lactate concentration during running by ratings of perceived exertion.

RPE from the response protocol was able to produce a blood [HLa] close to the criterion value during each 30-min run, and it is concluded that RPE is a valid tool for prescribing exercise intensities corresponding to blood [ HLa] of 2.5 mM and 4.0 mM.

The effects of blood lactate concentration on perception of effort during graded and steady state treadmill exercise.

The results suggest that the RPE: BLC relationship may be protocol dependent during graded exercise testing as it was only transferable from the Bruce GXT to the exercise training setting at intensities in the typical prescription range of 50-85% of VO2max.

Effect of exercise modality on ratings of perceived exertion at various lactate concentrations.

It was concluded that exercise modality does not affect the perception of exertion at LT, FBLC, or maximal exercise and that a strong relationship exists between RPE and blood lactate concentrations.

Perceived exertion associated with breathing hyperoxic mixtures during submaximal work.

Results indicate that during moderate and heavy work RPE is significantly affected by the inspired O2 concentration and there is a significant relationship between RPE and blood lactate.

Perceptual responses and blood lactate concentration: effect of training state.

Compared to nonrunners, runners also attained higher VO2, VE, and heart rate relative to peak values at LT and 2.0 mM, and there were no differences between groups in local, central, or overall ratings of perceived exertion (RPE) at any condition.

Self-monitored exercise at three different RPE intensities in treadmill vs field running.

The RPE method functioned well as a means of monitoring and regulating exercise intensity and showed high internal consistency for both velocity and HR between the first two trials at RPE 11.

Effect of blood pH on peripheral and central signals of perceived exertion.

Ratings of perceived exertion, blood acid-base, VO2, and cardiorespiratory responses were not differentially influenced by exercise mode, and RPE-A and L were positively related to blood [H+], and R PE-C was negatively related to VE for all exercise modes.

Ratings of perceived exertion at the lactate threshold in trained and untrained men and women.

The purpose of this study was to investigate the effects of state of training and gender on ratings of perceived exertion (RPE) at the lactate threshold (LT), and to determine whether RPE during

The influence of physical training and other factors on the subjective rating of perceived exertion.

RPE was higher for a given level of oxygen uptake during arm work than during leg work, as well as during bicycling compared to running or swimming, and a better correlation was found in these experiments between RPE and blood lactate concentration.

Gender comparison of RPE at absolute and relative physiological criteria.

RPE did not differ between gender when comparisons were made at relativized VO2 and HR reference criteria at exercise intensities between 70 and 90% of mode specific maximal/peak values.
