Abstract
BACKGROUND: The Single-Leg Wall Squat (SLWS) produces high electromyographic activity of lower extremity muscles, but it has not been thoroughly studied, especially as a performance test. Clinicians and athletes use performance tests to monitor progress, so the SLWS may be useful given its ability to challenge multiple lower extremity muscles. PURPOSE: To determine if there is a correlation between handheld dynamometry (HHD) for hip extension, hip abduction, knee extension and SLWS repetitions performed to failure. Secondary purposes included determining average values for the test in university students, reasons for test failure, difference between male and female performances, and relationship between the SLWS Test and changes in heart rate and Rated Perceived Exertion (RPE). METHODS: Data from thirty participants were used for the study (17 male, 13 female). Participants' hip extension, hip abduction, and knee extension strength were measured twice by researchers with HHD. Participants then performed a SLWS to failure. Heart rate and knee flexion angles were measured before the SLWS Test. Heart rate and RPE were measured after the test. Pearson correlation coefficients were used to determine the relationship between lower extremity strength and performance on the SLWS Test. Differences between sexes were analyzed using a paired t-test. RESULTS: The SLWS Test demonstrated low correlation with hip extension (r=0.23), hip abduction (r=0.23), and knee extension (r=0.30). There were no significant differences between male and female performances. Females averaged 63.5 +/- 38.1 and males averaged 85.9 +/- 30.4 repetitions. Average RPE was 8.27 +/- 1.18 on a scale of 10 at the conclusion of the SLWS Test. Most participants (43.3%) reported gluteus maximus fatigue as the primary reason for test termination. CONCLUSION: The SLWS was not highly correlated with performance on any of the HHD measures, indicating it should be used as an adjunct rather than a proxy for those strength tests. Limitations include only the use of university students and insufficient recovery from HHD before the SLWS test. Further research utilizing this test with larger or athletic populations may be beneficial.
