Behavior of muscle strength and the cycle circalunar
Abstract
The goal of the present study was to investigate the behavior of muscle strength developed daily in 10 repetition maximum (10RM) and compare it with days of the week. Twenty volunteers trained in strength training were submitted to an anthropometric evaluation, followed by a familiarization test in the bench press exercise (shoulder horizontal adduction) with 3 to 5 attempts with 3-5 min intervals, which were repeated after six weeks of training during five days of the week (Monday to Friday) to obtain the averageload, in the period from 17:00 to 19:00h and resting for at least 48h. The results were expressed as mean ±SD, and the load of 10RM during the week was compared using analysis of variance (ANOVA) one way and Tukey post hoc test (α=0,05). In the familiarizationtest was obtained 79 ± 18.4 kg, followed by the tests were obtained loads equivalent to 85.3 ± 18.9 kg, 87.7 ± 19.4 kg, 89.1 ± 18.6 kg, 91 ± 19.9 kg and 91.3 ± 19.4 kg, respectively for Monday, Tuesday, Wednesday, Thursday and Friday, representing an average variation of 1.5 kg, no being significant. In conclusion, the present study showed a linear behavior of the loads of 10RM during the week, however, no significant difference.
