Postactivation Potentiation of Bench Press Throw Performance Using Velocity-Based Conditioning Protocols with Low and Moderate Loads

( p < 0.001, Hedges’ g = 1.2). Peak velocity was significantly higher under the 60%_90_v condition compared to: (a) the 40%1RM_90v condition from the 0.75 ( p < 0.001, Hedges’ g = 1.5) till the 8 th minute ( p < 0.001, Hedges’ g = 1.2) of recovery (b) (b) the 60%1RM_70v condition in all time points ( p < 0.001, g > 1.2) (c) the 40%1RM_70v condition in all time points ( p < 0.05, g > 1.2) except the 10 th time point of recovery ( p = 0.29).

A Preliminary Analysis of Relationships between a 1RM Hexagonal Bar Load and Peak Power with the Tactical Task of a Body Drag

., 2017b ; Lockie et al., 2018c , in press). The correlation strength was designated as: an r between 0 to ±0.3 was considered small; ±0.31 to ±0.49, moderate; ±0.5 to ±0.69, large; ±0.7 to ±0.89, very large; and ±0.9 to ±1, near perfect for relationship prediction ( Hopkins, 2002 ). Stepwise linear regression analyses ( p < 0.05), with sex as a control variable, were conducted for each drag to illustrate whether absolute 1RM HBD, relative 1RM HBD, or peak power predicted standard or adapted drag performance for the 74.84 kg or 90.72 kg dummies.
