The competition in powerlifting has been divided into two divisions, with gear equipment (EQ) and without gear equipment (RAW). When competing in the EQ division, additional supportive gear can be worn by the athletes, while in the RAW division such gear is not allowed. The aim of the study was to compare the results of the RAW and EQ powerlifting divisions based on the results of world championships and current world records. One-hundred and twenty powerlifters (63 men, 57 women) were included to the analysis. Post hoc analysis for the results of men's world championships indicated significantly higher results of the barbell squat (SQ; p < 0.001; ES = 1.31), bench press (BP; p < 0.001; ES = 1.27) and deadlift (DL; p < 0.001; ES = 0.37) for EQ compared to the RAW division. Post hoc analysis for the results of women's world championships indicated significantly higher results of the SQ (p < 0.001; ES = 1.31), BP (p < 0.001; ES = 1.13) and DL (p < 0.001; ES = 0.71) for the EQ compared to the RAW division. Post hoc analysis for men's world record indicated significantly higher results in the SQ (p < 0.001; ES = 1.32) and BP (p < 0.001; ES = 1.24) for the EQ compared to the RAW division. Furthermore, there were no significant differences in the results of world records in the DL (p = 0.901; ES = 0.26) between the EQ and RAW divisions. Post hoc analysis for women's world records indicated significantly higher results in the SQ (p < 0.001; ES = 1.22) and BP (p < 0.001; ES = 1.99) for the EQ compared to RAW division. The main finding of the study was that supportive gear increases maximal load lifted during powerlifting competition.
力量举比赛分为两个组别，即使用装备组（EQ）和不使用装备组（RAW）。在EQ组比赛时，运动员可以穿戴额外的辅助装备，而在RAW组则不允许使用此类装备。本研究的目的是根据世界锦标赛的成绩和当前世界纪录，比较RAW组和EQ组力量举比赛的结果。120名力量举运动员（63名男性，57名女性）被纳入分析。对男子世界锦标赛成绩的事后分析表明，与RAW组相比，EQ组的杠铃深蹲（SQ；p<0.001；效应量=1.31）、卧推（BP；p<0.001；效应量=1.27）和硬拉（DL；p<0.001；效应量=0.37）成绩显著更高。对女子世界锦标赛成绩的事后分析表明，与RAW组相比，EQ组的SQ（p<0.001；效应量=1.31）、BP（p<0.001；效应量=1.13）和DL（p<0.001；效应量=0.71）成绩显著更高。对男子世界纪录的事后分析表明，与RAW组相比，EQ组的SQ（p<0.001；效应量=1.32）和BP（p<0.001；效应量=1.24）成绩显著更高。此外，EQ组和RAW组在DL世界纪录成绩上没有显著差异（p=0.901；效应量=0.26）。对女子世界纪录的事后分析表明，与RAW组相比，EQ组的SQ（p<0.001；效应量=1.22）和BP（p<0.001；效应量=1.99）成绩显著更高。该研究的主要发现是，辅助装备可提高力量举比赛中举起的最大重量。
