“…It has been clearly established that there is an inverse relationship between the weight to be lifted and the number of repetitions that can be performed [18, 19]. This relationship is of key importance for a coach in prescribing the appropriate load.…”

Prescribing training intensity and volume is a key problem when designing resistance training programmes. One approach is to base training prescription on the number of repetitions performed at a given percentage of repetition maximum due to the correlation found between these two measures. However, previous research has raised questions as to the accuracy of this method, as the repetitions completed at different percentages of 1RM can differ based upon the characteristics of the athlete. The objective of this study was therefore to evaluate the effect of an athlete's training background on the relationship between the load lifted (as a percentage of one repetition maximum) and the number of repetitions achieved. Eight weightlifters and eight endurance runners each completed a one repetition maximum test on the leg press and completed repetitions to fatigue at 90, 80 and 70% of their one repetition maximum. The endurance runners completed significantly more repetitions than the weightlifters at 70% (39.9 ± 17.6 versus 17.9 ± 2.8; p < 0.05) and 80% (19.8 ± 6.4 versus 11.8 ± 2.7; p < 0.05) of their one repetition maximum but not at 90% (10.8 ± 3.9 versus 7.0 ± 2.1; p > 0.05) of one repetition maximum. These differences could be explained by the contrasting training adaptations demanded by each sport. This study suggests that traditional guidelines may underestimate the potential number of repetitions that can be completed at a given percentage of 1RM, particularly for endurance trained athletes.

“…Alguns estudos observaram que uma intensidade específica de 1RM 8,22 ou um número pré-determinado de repetições 18 são melhores preditores da carga de 1RM por apresentarem maiores valores de variância explicada. De forma similar com relação a restrição da intensidade ou número máximo de A mesma inviabilidade pode ser encontrada para a utilização de uma faixa pré-determinada de repetições.…”

Resumo -O objetivo do presente estudo foi determinar equações que pudessem estimar a carga correspondente à carga máxima (1RM) a partir do número máximo de repetições com cargas submáximas no supino horizontal, puxador costas, e mesa flexora em mulheres familiarizadas com treinamento de força (n = 20; 22 ± 3 anos; 61 ± 7 kg; 165 ± 4 cm). O primeiro teste foi o teste de 1RM. Posteriormente, as participantes realizaram o número máximo de repetições nas intensidades de 70, 80 e 90% de 1RM em todos os exercícios, em diferentes dias. Para determinar cada equação, foi realizada a análise de regressão linear múltipla. Dois critérios foram considerados para aceitar cada equação: o coeficiente de determinação ajustado (R² aj. > 0,80) e o erro percentual (EP < 10%). Para todos os exercí-cios, as equações atingiram os critérios: supino horizontal: R² aj. = 0,89; EP = 5%; puxador costas: R² aj. = 0,84; EP = 5%; mesa flexora: R² aj. = 0,82; EP = 7%. Para a utilização das equações elaboradas, é necessário escolher uma carga aleatória e o número de repetições realizados nesta mesma carga para encontrar o valor de 1RM. Recomenda-se que o número de repetições esteja dentro da variação observada neste estudo: supino horizontal (1 -21), puxador costas (2 -20) e mesa flexora (1 -14).

“…Among the main indirect tests applied for evaluation of muscular strength are the one maximal repetition (1RM) and multiple repetitions (6)(7)(8)(9)(10) tests. The 1-RM test despite being one of the most used and mentioned by the literature, may be influenced by countless factors, once it requires great concentration and previous knowledge of the performance technique from the evaluated subject, besides other important characteristics (1) .…”

“…Within this context, researchers have searched to develop and/ or validate predictive equations for the estimation of the 1-RM values through submaximal tests, based on the performance of multiple repetitions (2,(4)(5)(6)(7)(8)(9)(10) . Nonetheless, little has been published concerning the validation of the majority of the predictive equations proposed so far for the estimation of 1-RM, as well as concerning the possible positive impact of the application of these equations in different situations which involve muscular strength analysis.…”

The aim of the present study was to analyze the validation of the equation proposed by Brzycki for the prediction of a maximum repetition (1-RM) in the bench press. Fifty sedentary or moderately active male subjects (22.2 ± 3.5 years; 64.7 ± 8.6 kg), were initially submitted to six test sessions of 1-RM in the bench press, with 48 hours of interval between each session, in order to determine the maximum workload. A protocol of force resistance was then performed for the determination of 7-10-RM. The used criteria for the validation included: t-Student test for dependent samples, for comparison among the mean values obtained by the predictive equation and by the 1-RM test; Pearson correlation coefficient for analysis of the association degree among the measurements; standard error of estimate (SEE) for evaluation of the mean deviation degree of the individual data along the produced line; total error (TE) for the verification of the mean deviation of the individual values of the identity line; constant error (CE) for analysis of the difference among the mean values obtained in the 1-RM test and predicted by the proposed equation. None statistically significant difference was verified among the values produced by the 1-RM test and the Brzycki equation (P > 0.05). Both the SEE and the TE were relatively low (2.42 kg or 3.4% and 1.55 kg or 2.2%, respectively), as well as the CE found (0.22 kg or 0.3%). Moreover, the correlation coefficient value found was extremely high (r = 0.99; P < 0.05), thus showing a strong association between the values found by the 1-RM test and the Brzycki equation. Therefore, the equation analyzed by this study satisfied the validation criteria established by the literature. The results suggest that the Brzycki equation seems to be a fairly attractive alternative for the estimation of 1-RM values in the bench press from the performance of submaximal tests of 7-10-RM, in sedentary or moderately active male adults.
