The Effects of Lateral Bounds on Post-Activation Potentiation of Change-of-Direction Speed Measured by the 505 Test in College-Aged Men and Women

Abstract

Forty recreationally-trained individuals completed four testing sessions to determine whether lateral bounds (LB) or weighted lateral bounds enhanced change-of-direction (COD) speed measured by the 505 COD speed test. Session 1 included vertical jump and lateral bound (LB) testing to measure power. Sessions 2–4 involved three randomized conditioning activities (CA): 3 × 5 LB; 3 × 5 weighted LB (10% body mass provided by a weighted vest); and a control condition (4-min rest). The 505 COD speed test was performed 5- and 2.5-min pre-CA, and ~15 s, 4, 8, 12, and 16 min post-CA. A 3 × 6 repeated measures analysis of variance (ANOVA) calculated performance changes across time points post-CA. A 3 × 2 repeated measures ANOVA analyzed best potentiated performance. Smallest worthwhile change (SWC) measured within-subject 505 COD speed test performance. Partial correlations controlling for sex calculated relationships between the vertical jump, LB, and percent potentiation. There were no differences (p = 0.919) in 505 time relative to baseline for any CA, nor was the SWC exceeded. The best potentiated 505 time was faster (p < 0.001) than baseline for all CA, with no between-CA differences. There were no significant (p = 0.056–0.993) correlations between power and potentiation. LB and weighted LB did not potentiate the 505 COD speed test, although performance was not hindered.

“…All statistical analyses were computed using the Statistics Package for Social Sciences (Version 26.0; IBM Corporation, New York, NY, USA). Normality of the fitness test data was confirmed by visual analysis of the Q-Q plots [ 45 , 46 , 47 ]. Descriptive statistics (mean ± standard deviation (SD)) were calculated for each variable.…”

The Effects of the Barbell Hip Thrust on Post-Activation Performance Enhancement of Change of Direction Speed in College-Aged Men and Women

“…The first exercise in the complex pair is often referred to as a conditioning activity (CA). There has been some analysis of PAPE and COD speed [9][10][11].…”

“…Although there was a not a significant decrease in shuttle run times 4, 8, and 12 min post-CA, Sole et al [10] noted that due to individual responses, there was potential application of PAPE for COD speed. Orjalo et al [11] analyzed whether 3 sets × 5 repetitions of lateral bounds (unweighted and performed with an additional load of 10% body mass) could enhance COD speed as measured by the 505 COD speed test. The results suggested that the overload provided by lateral bounds was not sufficient to potentiate 505 COD speed test time.…”

“…The results suggested that the overload provided by lateral bounds was not sufficient to potentiate 505 COD speed test time. One of the recommendations from Orjalo et al [11] was to analyze whether heavy-resistance exercises were more appropriate to induce a PAPE effect on COD speed.…”

“…Lastly, it was hypothesized that there would be significant relationships between absolute and relative BHT load and percent potentiation in the 505 COD speed test [17,18]. [11], G*Power software (v 3.1.9.3, Universität Kiel, Düsseldorf, Germany) confirmed post hoc that 40 subjects within a 2 × 5 repeated-measures analysis of variance (ANOVA,) indicated data could be interpreted with an effect level of 0.2 and power level of 0.9, when significance was set at 0.05 [23]. Furthermore, 40 subjects for the 2 × 2 repeated-measures ANOVA allowed data to be interpreted with an effect level of 0.25 and power level of 0.8, when significance was set at 0.05 [23].…”
