to quantify internal TL using a modification of the rating of perceived exertion (RPE) method developed by Borg. 6 This method is known as the session RPE (sRPE). The sRPE is derived by multiplying the overall RPE obtained at the end of a training session, using the Borg category-ratio 10 scale

. Consequently, the session rating of perceived exertion (sRPE), an athlete’s subjective RPE multiplied by session duration (in minutes), has been established as a simple and valid measure of ITL. 7 Based on the formative research of Foster et al, 8 sRPE is typically reported 30 minutes following session

On the other hand, intensity can be quantified using different methods, such as heart rate (HR) monitoring, blood lactate concentrations, and the (session) rating of perceived exertion

’s psychobiological training load is the session rating-of-perceived-exertion (s-RPE) training load (session duration [in minutes] × RPE [using either CR-10, CR-100 or 6–20 scales]). 2 Several early studies established the construct validity of s-RPE training load against other forms of internal load (such as heart

, velocity, distance, cadence, and gearing were monitored continuously during each trial (sample frequency = 4 Hz). Rating of perceived exertion on a Borg scale of 6 to 20 17 was asked after the warm-up; at 100, 200, and 300 seconds after starting the TT; and directly after passing the finish line

Purpose:

The session rating of perceived exertion (sRPE) has gained popularity as a “user friendly” method for evaluating internal training load. sRPE has historically been obtained 30 min after exercise. This study evaluated the effect of postexercise measurement time on sRPE after steady-state and interval cycle exercise.

Methods:

Well-trained subjects (N = 15) (maximal oxygen consumption = 51 ± 4 and 36 ± 4 mL/kg [cycle ergometer] for men and women, respectively) completed counterbalanced 30-minute steady-state and interval training bouts. The steady-state ride was at 90% of ventilatory threshold. The work-to-rest ratio of the interval rides was 1:1, and the interval segment durations were 1, 2, and 3 min. The high-intensity component of each interval bout was 75% peak power output, which was accepted as a surrogate of the respiratory compensation threshold, critical power, or maximal lactate steady state. Heart rate, blood lactate, and rating of perceived exertion (RPE) were measured. The sRPE (category ratio scale) was measured at 5, 10, 15, 20, 25, 30, and 60 min and 24 h after each ride using a visual analog scale (VAS) to prevent bias associated with specific RPE verbal anchors.

Results:

sRPE at 30 min postexercise followed a similar trend: steady state = 3.7, 1 min = 3.9, 2 min = 4.7, 3 min = 6.2. No significant differences (P > .05) in sRPE were found based on postexercise sampling times, from 5 min to 24 h postexercise.

Conclusions:

Postexercise time does not appear to have a significant effect on sRPE after either steady-state or interval exercise. Thus, sRPE appears to be temporally robust and is not necessarily limited to the 30-min-postexercise window historically used with this technique, although the presence or absence of a cooldown period after the exercise bout may be important.

Ratings of perceived exertion (RPE) have been proposed as a simple, noninvasive method to assess exercise intensity. 1 When multiplied by exercise duration, RPE can be used to assess internal training load (TL), this being named session-RPE (sRPE). 2 Traditionally, sRPE has been obtained by using
