Correlação do desempenho de força máxima mensurado em teste de 1RM realizados no aparelho pulley, barra fixa e campus board

Abstract

The strength training instruction can be based on percentages of tests of a one repetition maximum (1RM), provided that the sports movement has an engine pattern similar to that of the test. In sport climbing, the development of upper-limb strength is mainly responsible for performance improvement. The application of 1RM tests on the Campus Board (CB) would be more specific for climbers. Still, it would also present more significant difficulties in controlling joint amplitudes, accessory movements, and how to adhere the weight to the body. However, a test performed in a device that uses the same muscle groups and movements as the pulley in a more standardized manner may show a high correlation with a more specific test. Regardless of the selection of exercises, the body part evaluated, or the athletes' experience, the 1RM test is reliable. This study aimed to determine the correlation between the 1RM test performed in the pulley, the fixed bar, and the Campus Board. 15 male bodybuilding practitioners were selected (age = 32.6 ± 7.4 years; height = 1.76 ± 0.1 m; mass = 77.0 ± 12.6 kg). There were four collection sessions. The first session focused on familiarizing the 1 RM test in the pulley and the fixed bar. On days two and three, the test was randomized on the pulley or fixed bar. On the fourth day, 8 participants of the original sample performed the CB test starting with the 1RM value of the fixed bar test. Kendall's correlations were calculated between the 1RM results of the pulley, the fixed bar, and the CB using the statistical program R Studio and adopted the significance level of p < 0.05. The results showed a strong and positive correlation between 1RM in the pulley and fixed bar (τ = 0.74, p < 0.001) and between the pulley and the CB (τ = 0.72, p = 0.016). The mean values of 1RM were (pulley = 92.5 ± 13.6 kg; fixed bar = 95.5 ± 16.1 kg; CB = 99.1 ± 15.5 kg). These findings indicate that some factors determinant to the performance of 1RM are common to the three tests. Trainers can develop regression equations that allow the estimative of the value of 1RM in CB and fixed bar through the pulley 1RM test, facilitating the monitoring of muscle strength training loads.
