Abstract

The objectives of this study was to verify if the standard force tables are practicable, if there is difference between the number of maximum repetitions (RM) intra-exercise and between muscular groups, for the same intensity. The sample is composed by 20 individuals of the masculine sex, between 17 and 30 years. Load tests, maximum and RM were applied, for the pectoral muscular group and quadriceps. The statistics analysis was carried through to the level of significance P=0,05. The straight supine year-end results (MR.) compared the extensive chair (CE), presented statistic difference for intensity 80% (P < 0,05). The results of the CE were superior to the ones of MR., except for 50% intensity. The intra-exercise analysis presented statistic difference (P < 0,05) in the straight supine in different percentages of strength. For the CE there was not statistic difference for the intensities 60-70% and 70-80%. The analyzed tables were shown without standardization of values, with enormous variations of values between diverse tables and the number of repetitions between upper/lower member. One concludes that different bands of strength provide differences in the RM number, between individuals and muscular grouping. The limitations of these standard tables evidence the importance of individualized strength programs.
