Resumen
The aim of this study was to examine the test-retest reliability and concurrent validity of the PUSH Band (TM) 2.0 to measure barbell's velocity during unconstrained (free-weights) and constrained (Smith machine) squat exercises. After an initial assessment of the Smith machine squat one-repetition maximum (1RM), 24 resistance-trained males completed one or two testing sessions separated by 7 days. In one session, the squat was performed with free-weights (n = 22), while in another session, the Smith machine was used (n = 16). Both testing sessions consisted of two blocks of eight repetitions (three repetitions at 45%1RM, three repetitions at 65%1RM, and two repetitions at 85%1RM). The mean velocity of the lifting phase was simultaneously recorded with the PUSH Band (TM) 2.0 and a gold-standard linear velocity transducer (T-Force(R) System). The PUSH Band (TM) 2.0 generally revealed an acceptable reliability (CVrange = 5.81%-13.14%), but the reliability was always greater for the T-Force(R) System (CVrange = 2.95%-7.86%). Regardless of the squat exercise, the concurrent validity of the PUSH Band (TM) 2.0 with respect to the T-Force(R) System was generally low at 45%1RM (ESrange = 0.18-0.33, r(range) = 0.58-0.75, SEErange = 0.04-0.05 ms(-1) and 4.2%-6.0%), 65%1RM (ESrange = 0.26-0.44, r(range) = 0.63-0.82, SEErange = 0.04-0.06 ms(-1) and 6.0%-9.2%), and 85%1RM (ESrange = 0.61-0.64, r(range) = 0.66-0.82, SEErange = 0.05-0.07 ms(-1) and 11.4%-16.0%). Taken together, these results suggest that the PUSH Band (TM) 2.0 is a reliable, but not valid, wearable technology to measure the barbell velocity during the free-weight and Smith machine squat exercises.
