Analysis of the effect of circuit-training training on the subjective perception of effort and repetitions in young men
Abstract
Professionals in the field of physiology applied to sport, seek to find the best way to control the intensity of effort and efficient and reliable methods for prescription and monitoring of training loads. The objective of the present study was to analyze the effects of a single session of circuit-training in resistance exercise on parameters of subjective perception of effort and repetitions, as well as correlating them. Healthy, physically active males (n = 15) with a mean age of 21.60 ± 3.81 were submitted to a circuit resistance exercise protocol. The resistance group performed 8 exercise stations alternating arm and leg at 70% of 1RM with 3 laps of 15 repetitions and 1 minute rest between laps. At the end of each lap PSE was collected through the OMNI-res table, while the number of repetitions in each exercise was counted and quantified for each lap and exercise. Results: There was a significant difference in the maintenance of the number of repetitions and in the execution time of the lap. In the subjective perception of effort there was also a difference. It was concluded, therefore, that there is an intimate relation between PSE and the number of repetitions, whereas, both variables were influenced by the load, cadence of movement and time of rest and lactate, being thus the repetitions were diminishing to the round the circuit.
