The purpose of this cross-sectional study is to determine if the 30-second Roll to Quadruped test (30RQ) can serve as a baseline measurement for rolling capacity and correlate with participants' physical capabilities, specifically upper and lower extremity strength, core strength, functional strength, age, gender, activity levels, and BMI.
Nineteen adults (age range: 20-40 years) without musculoskeletal impairments participated in this study. Muscle strength was assessed using hand-held dynamometry at the shoulder, hip, elbow, and knee. Functional strength and mobility were evaluated with the 30-second chair stand test (30 CST) and the plank test. The 30RQ test involved participants performing repeated supine-to-quadruped rolls for 30 seconds, with the number of successful rolls recorded. Video recordings captured rolling strategies for qualitative and quantitative analysis.
Statistically significant correlations (p 0.05) existed with increased performance during the 30RQ test and increased hip horizontal abduction strength (r=0.575) and 30 CST scores (r=0.495). Statistically significant correlations (p 0.01) also existed with increased performance during the 30RQ test and male gender (r=0.770), increased hip abduction strength (r=0.751), increased hip flexion strength (r=0.785), increased hip extension strength (r=0.726), increased knee flexion strength (r=0.685), increased knee extension strength (r=0.671), increased shoulder flexion strength (r=0.737), increased shoulder abduction strength (r=0.759), increased shoulder abduction strength (r=0.707), increased shoulder adduction strength (r=0.789), and increased elbow extension strength (r=0.655).
Increased performance on the 30RQ test had a moderate or strong association with hip, knee, shoulder, and elbow muscle strength measurements, male gender, and 30 CST.
This study determined that the 30RQ test correlates well with most of the muscle strength assessments in this study. Additional studies with larger sample sizes are needed to validate the utility of the 30RQ test to determine functional and clinical hip, knee, shoulder, and elbow strength.
