Comparison of heart rate and subjective perception of effort during functional training

Abstract

Functional training has gained an increasing opening in different spaces for the practice of physical exercises, carried out by people of different ages, from children to the elderly. The present study aimed to understand the relationship between Heart Rate (HR) and the Subjective Perception of Effort (PSE). Data collection was carried out at Personalis academia, located in the city of Marau-RS, the sample consisted of 30 women, aged 33.1 ± 11.1 years and participants in Functional Training for at least thirty days. They were invited to participate in the data collection that took place during classes held in a single group, during the 12-week period, in the circuit methodology, after signing the IC in accordance with the protocol approved by the UPF CEP (opinion no. 4,078,821). HR was assessed by means of the frequency meter, and PSE by the Borg scale. The HR presented an oscillation of 82 ± 9 bpm at rest until 141 ± 25 bpm at the end of the training and the PSE from 4 ± 1.5 at rest until 13 ± 2.37 at the end of the training, the two variables presented the biggest jump in the starting from the resting state, until the end of the warm-up, remaining moderately throughout the training, a linearity was identified in the variations of the two indicators. It may be suggested to use them as a training intensity control.
