MONTEIRO, Walace; SIMAO, Roberto and FARINATTI, Paulo. Manipulation of exercise order and its influence on the number of repetitions and effort subjective perception in trained women. Rev Bras Med Esporte [online]. 2005, vol.11, n.2, pp. 146-150. ISSN 1806-9940. http://dx.doi.org/10.1590/S1517-86922005000200010.
Resistance exercises (RE) are prescribed in function of the combination of several variables. For some variables such as the exercises ordering, the evidences that guide the available recommendations reveal to be insufficient. The objective of this study was to investigate the influence of different RE execution orders on the number of repetitions and effort subjective perception (ESP) in trained women. The sample was composed of 12 women (22 ± 2 years) with at least six months of practice in RE. The data were collected in five alternated days. In the first, the PAR-Q questionnaire was applied, anamnesis for the identification of the physical activities performed and the anthropometrical measures. In the second and third days, the maximal load was measured and the reproducibility of the 10-maximum repetitions tests (10RM) in the selected exercises was tested. In the fourth and fifth days, the sessions with the two sequences proposed (SEQA and SEQB) were performed; one session with exercises involving the larger muscular groups and the other involving the smaller ones. Thus, the following exercises were performed in the SEQA: horizontal supine (HS), standing development (SD) and triceps in the pulley (TR), while in the SEQB, the following order was performed: TR, SD and HS. The volunteers performed three series of each exercise with loads of 10RM and intervals of three minutes between series and exercises. In each series, the maximum number of repetitions was measured. The results revealed significant differences in the average of repetitions in each sequence for all exercises, unlike what was observed for the ESP. In the sequences investigated, the last exercise performed always presented a lower number of repetitions, regardless the muscular group involved. In short, the exercise order tended to change the performance in both sequences observed, at least with regard to the training volume. This influence was more associated with the position of the exercise in the sequence than with the size of the muscular group or with the number of joints involved. The ESP results were similar in both sequences, suggesting that its value as fatigue indicative in RE sessions should be better analyzed.
