Bottom Line: The aim of the present study was to analyse the usefulness of the 6-20 rating of perceived exertion (RPE) scale for prescribing and self-regulating high-intensity interval training (HIT) in young individuals.No significant difference between sessions was observed in HR during low- (HR: 135±15 bpm; RPE: 138±20 bpm) and high-intensity intervals (HR: 168±15 bpm; RPE: 170±18 bpm).This finding suggests that the 6-20 RPE scale may be a useful tool for prescribing and self-regulating HIT in young subjects.

ABSTRACT
The aim of the present study was to analyse the usefulness of the 6-20 rating of perceived exertion (RPE) scale for prescribing and self-regulating high-intensity interval training (HIT) in young individuals. Eight healthy young subjects (age = 27.5±6.7 years) performed maximal graded exercise testing to determine their maximal and reserve heart rate (HR). Subjects then performed two HIT sessions (20 min on a treadmill) prescribed and regulated by their HR (HR: 1 min at 50% alternated with 1 min at 85% of reserve HR) or RPE (RPE: 1 minute at the 9-11 level [very light-fairly light] alternated with 1 minute at the 15-17 level [hard-very hard]) in random order. HR response and walking/running speed during the 20 min of exercise were compared between sessions. No significant difference between sessions was observed in HR during low- (HR: 135±15 bpm; RPE: 138±20 bpm) and high-intensity intervals (HR: 168±15 bpm; RPE: 170±18 bpm). Walking/running speed during low- (HR: 5.7±1.2 km · h(-1); RPE: 5.7±1.3 km · h(-1)) and high-intensity intervals (HR: 7.8±1.9 km · h(-1); RPE: 8.2±1.7 km · h(-1)) was also not different between sessions. No significant differences were observed in HR response and walking/running speed between HIT sessions prescribed and regulated by HR or RPE. This finding suggests that the 6-20 RPE scale may be a useful tool for prescribing and self-regulating HIT in young subjects.

Figure 0002: Heart rate (left panel) and walking/running speed (right panel) during HIT session prescribed and regulated by heart rate (HR session) or rating of perceived exertion (RPE session) response. No significant differences were observed between sessions.

Mentions: No significant differences in HR were observed between HIT sessions prescribed and regulated by HRRESERVE or RPE (Figure 2). HR values at low-intensity intervals (∼50% of HRRESERVE or 9-11 points on the RPE scale) were 135 ± 15 bpm and 138 ± 20 bpm (P = 0.36), whereas HR values at high-intensity intervals (∼85% of HRRESERVE or 15-17 points on the RPE scale) were 168 ± 15 bpm and 170 ± 18 bpm (P = 0.38) during HIT sessions prescribed and regulated by HRRESERVE or RPE, respectively.
