- Abstract
Introduction: The purpose of the present work was to value the association between Dynamic Maximum Strength (DMS) and the Repetition Maximum Number (RMN) in the Squat exercise with knees bended at 90° (SQ90), as well as with dynamic parameters. Materials and methods: Using 9 students of Sciences of the Physical Activity and Sports, familiarized with SQ90, two parameters of DMS were obtained: 1 Repetition Maximum (1RM) and 1 RM relative to the corporal weight (RM/PC). A test (RF90) that involved performing the maximum serial number of 1 repetition of SQ90 with a load of 90% of 1 RM and 30sec of recovery was done later. With 7 people the NRM with 70% of 1Rm was also obtained (RF70). Results: There was a great dispersion in NRM values (RF90: 13±10.86; RF70: 32.28±13.80). There were not statistically significant correlations between NRM and 1RM or NRM and RM/PC. There was no association among 1RM and dynamic modification rates in RF90 or RF70. Correlation was highly significant between RM/PC and the percentile value of the average power with respect to the repetition of maximum power in RF70 (r=-0.911; p=0.004). Conclusion: The dates of the present work show variability in performance of resistance tests to the strength, specially particularly in RF90. The results do not allow us to confirm that this diversity is dependent on development of DMS.
