- Abstract
Introduction: The trunk flexor endurance test (TFET) has been used with variations in the inclination angle from 45 to 60 degrees. Specifically, an inclination angle of 60 degrees is deemed suitable for older adults, yet may be overly simplistic for athletes. The clinical relevance of TFET could differ based on the inclination angle and populations. Objectives: This study aims to investigate the association between different TFET angles and trunk performance. Study Design: A correlational analysis approach. Methods: The participants consisted of 350 physical education students (236 men, 114 women), divided into three groups based on angles (45, 50, and 55 degrees). The TFET commenced by moving the backrest 10 cm backwards at the designated angle while participants maintained the initial posture. The test concluded when participant's back contacted the backrest again. Trunk performance was evaluated through 30-second speed sit-ups, trunk extensor endurance test (TEET), closed kinetic chain upper extremity stability test (CKCUEST), and upper quarter Y balance test (UQYBT). Results: Among men, a significant difference was noted between 45 and 55 degrees, whereas no significant difference was observed among women across angles. For men, correlation analysis revealed significant associations between TFET and sit-ups (r=.32 with 45 degrees, r=.37 with 50 degrees, r=.27 with 55 degrees), TEET (r=.54 with 50 degrees), and UQYBT (r=.30 with 55 degrees). For women, significant correlations were observed between TFET and sit-ups (r=.49 with 45 degrees, r=.61 with 55 degrees), TEET (r=.38 with 45 degrees), CKCUEST (r=.35 with 45 degrees, r=.31 with 50 degrees), and UQYBT (r=-.37 with 55 degrees). Conclusions: Our findings showed that the angle of TFET influences both the endurance capacity and the outcomes on trunk performance tests. The variation in TFET duration across different angles underscores the importance of selecting appropriate angles to accurately assess the physical fitness levels of diverse populations.
