AP (anaerobic power) output is an important physical characteristic that is required to succeed in sports such as wrestling. The Wingate test is considered the Gold Standard for assessing AP but is not specific to the sport of wrestling. The purpose of this study was to examine the reliability of a novel field test known as the LWAPT (Lopez wrestling anaerobic power test) for the assessment of AP. The participants were male high school wrestlers (n = 10, age: 17.0 ± 0.8 yrs, mass: 70.9 ± 10.2 kgs). The participants met on one occasion in order to complete the testing protocol. The protocol initiated with the participants completing a 10-15 minute dynamic WU (warm-up) that included three practice dummy throw attempts (dummy mass = 31.75 kgs). Following the dynamic WU (≈ 5 minutes), the participants performed two trials of the LWAPT. In order to perform the LWAPT, wrestlers stood behind the wrestling dummy in a squat position with legs bent at 45-90 degrees. Next the wrestlers wrapped their arms around the waist of the dummy and on the signal “go” the wrestlers quickly exploded up, lifting the dummy by getting triple extension with the ankles, knees and hips as one would in a power clean. After the wrestler was fully extended, he turned in midair in order to drive the dummy onto its stomach on the ground, where the wrestler was on top of the back of the dummy (a common position after an opponent has been thrown). The participant then repositioned the dummy to the original position to execute another throw. The participants completed as many dummy throws as possible during the one minute trials. The LWAPT trials were separated by 15 minutes. The trial scores were 15.6 ± 2.5 and 17.2 ± 1.5 throws respectively. The interclass and intraclass reliability coefficients were r = 0.84 and ICC = 0.80. The standard error of the measure was SEm = 1.0 throws with 90% confidence limits of UL: 1.7, LL: 0.7. The mean difference between trials was 1.6 ± 1.4 throws (90% confidence limits of UL: 2.4, LL: 0.8). Bland-Altman plots suggested agreement between trials with no evidence of heteroscedasticity. The LWAPT exhibits moderate to high reliability as an assessment of AP. The inclusion of additional dummy throw trials to the assessment protocol may enhance the degree of reliability of the dummy throw test as a measure of AP.
