Aim • Establish reliability and convergent construct validity of Edgren Side Step Test (ESST), T-Test, and Illinois Agility Test (IAT) in young, nondisabled, physically active male servicemembers (SMs). • Relevance • Performance-based outcomes have been used to assess agility in athletes and nonathletes. • However, reliability and validity have not been established.
Method • 97 male Active Duty U.S. Army SMs completed ESST, T-Test, and IAT twice within 24–48 h.
Results • No significant differences between ESST (p = 0.10), T-Test (p = 0.09), and IAT (p = 0.23). • Reliability: • Excellent interrater. • Moderate to good test-retest. • Relationship between tests: • Good positive between IAT and T-Test (r = 0.76, p < 0.001). • Moderate negative between ESST and both T-Test (r = –0.69, p < 0.001) and IAT (r = –0.65, p < 0.001).
Conclusion • These tests are valid measures of agility. • They uniquely assess movement in different planes, thus providing a comprehensive assessment of high-level mobility.
