“…Between each 1RM attempt, subjects rested for 3–5 minutes. Because of the high reliability reported previously, the 1RM tests were performed once for each movement (5,7,19,23,24,31). All foundation strength exercises were technically performed in agreement with the guidelines of the International Weightlifting Federation, available at https://iwf.sport/2018/03/14/exercises-prepare-olympic-lifts/, and previous studies and weightlifting manuals (3,11,14,18,21,22,38).…”

Zecchin, A, Puggina, EF, Hortobágyi, T, and Granacher, U. Association between foundation strength and weightlifting exercises in highly trained weightlifters: support for a general strength component. J Strength Cond Res 37(7): 1375–1381, 2023—In addition to specific weightlifting exercises (i.e., clean and jerk and snatch), foundation strength exercises (i.e., overhead press, front squat, and deadlift) constitute an integral part of the weightlifters' training regime. The unexamined concept behind this training plan is that foundation strength exercises are associated with clean and jerk and snatch performance, implying the existence of a general strength component. We thus determined the relationship between performance in foundation strength exercises (overhead press, front squat, and deadlift) and weightlifting exercises (clean and jerk and snatch) in weightlifters. Well-trained weightlifters (N = 19, age: 26.8 ± 4.4 years; body mass index: 27.6 ± 2.3 kg·m−2; and training history: 4.6 ± 0.8 years) performed 1 repetition maximum tests (1RM) in foundation strength and weightlifting exercises, over 14 days, in a randomized order. We observed significant correlations in 1RM performance between the overhead press and snatch (r = 0.69), front squat and snatch (r = 0.73), overhead press and clean and jerk (r = 0.67), and front squat and clean and jerk (r = 0.72, all r values: p < 0.01). No significant correlations were found for 1RM performance between the snatch and deadlift or between the clean and jerk and deadlift (r-range: 0.20–0.58; p > 0.05). Stepwise linear regression revealed that 1RM performance in the overhead press and front squat explained 62% of the variance in snatch 1RM performance (F = 5.51; p < 0.04). Overhead press and front squat 1RM performance explained 59% of the variance in the clean and jerk 1RM performance (F = 5.14; p < 0.04). Our results demonstrate the existence of a general strength component between selected foundation strength exercises and weightlifting performance. However, the use of the front squat and overhead press to increase 1RM performance in weightlifting exercises needs to be determined in future research using a different methodological approach (i.e., longitudinal protocols), given that the observed correlations do not necessarily imply causation.

Reprodutibilidade do teste de 1-rm e dor muscular tardia em homens idosos saudáveis

et al. 2011

O teste de uma repetição máxima (1 RM) tem sido amplamente utilizado na investigação científica do treinamento de força. Contudo, alguns estudos observaram difícil reprodutibilidade para esse teste em idosos, quando não são observados cuidados metodológicos como: familiarização, controle da velocidade de execução e número limitado de tentativas. Sendo assim, o presente estudo teve como objetivo analisar a reprodutibilidade do teste de 1 RM. Vinte homens idosos (65 ± 5 anos) saudáveis, sem nenhum treinamento físico sistemático e regular participaram como amostra. O teste de 1 RM foi realizado nos exercícios de supino reto e extensão de joelhos. Foram realizados 2 testes, separados por 4 semanas. Os procedimentos para a realização do teste incluíram 1 sessão de familiarização 48 horas antes do primeiro teste. Após 48 horas do primeiro teste de 1RM foi aplicado o instrumento da dor muscular tardia (DMT) na forma de escala adaptada (Likert de 10 pontos). Os resultados demonstraram que houve correlação significativa entre os testes com r = 0,99 e 0,97 para a extensão de joelhos e supino, respectivamente (p < 0,0001) e ICC= 0,99 para ambos os exercícios. Com relação à escala de dor, a opção nenhuma sensação de DMT, obteve a unanimidade das respostas. Nosso estudo demonstrou que o teste de 1 RM é altamente reprodutível e sugere que após 48 horas da execução do mesmo esse teste não resulta em qualquer sensação subjetiva de DMT.
