Associations Between Two Measures of Trunk Muscular Endurance Among Male Law Enforcement Officers
The purpose of this study was to explore the relationship between two measures of trunk muscular endurance.
Retrospective data for 520 male law enforcement officers (age 40.16 ± 7.71 years; height = 1.81 ± 0.07 m; body mass = 94.4 ± 15.01 kg) belonging to a single US based law enforcement agency were used for this analysis. The data provided included: age, height, body mass, sit-up repetitions completed in 1-min (SU) and time to completion for the isometric prone plank (IPP). A Pearson’s product correlation coefficient was used to determine the relationships between the SU and IPP.
Significant (P < 0.001) moderate (r = 0.594, R 2 = 0.352) relationships were discovered between the SU and IPP.
Based on the results of this study it appears that both the SU and IPP tests are appropriate for evaluating trunk muscular endurance, but measure separate qualities (i.e., dynamic and static muscular endurance).
