Are rating of perceived exertion and heart rate methods useful to monitor the internal training load in functional training?

Aim: The study aimed to quantify and characterize the Training Load (TL) in a Functional (FT) model using Heart Rate (HR) Session Rating of Perceived Exertion (sRPE) methods, verify whether these methods could be valid monitor TL during FT program. Methods: design consisted two phases: phase 1 - composed single training session (FTSESSION), which HR, sRPE, pre- post-exercise lactate [La] levels were assessed; 2 program (FTPROGRAM) with eight weeks duration sessions per week. HR SRPE utilized all sessions, results between vs. 8, 8 9, 9 16 compared. Results: On 1, distribution demonstrated that participants spent about 75% total time above 80% HRmax. Post-exercise values significantly higher (p < 0.05) than pre-exercise. mean sRPE score was 8.5 ± 1.2. In 2, different 1-8 8-9 0.05). A strong correlation (r = 0.790) internal load (ITL) impulse (TRIMP) observed. Conclusion: Our data FTSESSION can characterized as high-intensity exercise, based on pattern responses reinforced by [Lapeak]. Also, monitoring (sRPE TRIMP) proved for programs.
