Meta-analysis Of The Effect Of SAQ Training On The Agility Quality Of Soccer Players

OBJECTIVE: To investigate the effect of SAQ training on the sensory quality of soccer players using Meta-analysis.METHODS: The foreign databases Pubmed,Web of Science,Ebsco,Embase,Scopus,MEDLINE,and the domestic databases China Knowledge Network,Wanfang,and Vipshop was searched for the keywords SAQ,soccer players,and sensitivity quality,and the inclusion and exclusion criteria were set according to the study requirements,and the Endnote 20 software was used to screen The data were statistically analyzed using the software Stata14.0 and Revman 5.4.Results: 1.2202 papers were initially searched and screened,and17 papers finally met the inclusion and exclusion criteria.Cochrane risk of bias assessment was used,and the overall quality of the included 17 literature was high,using randomized grouping,only 5 had subjects drop out,and none of them had selective reporting or other biases.2.SAQ training showed a large effect on the T-run test index,Illinois test index intervention,with a significant effect and significant significance;505 varimax test,the Nebraska test,AFL sensitivity test indicators were moderate,505 directional test was not significant,and the latter two were significant.(1)T-run test indicators were included in 12 studies and showed large effects,high heterogeneity,and highly significant differences.The results of subgroup analysis: training period subgroup showed a large effect,and high heterogeneity,≥8 weeks subgroup had a significant difference,<8 weeks subgroup had no significant difference,the former effect was greater than the latter effect;the training frequency subgroup showed a large effect,high heterogeneity,both groups had a significant difference,the effect of 3 times a week and above training was better than 1-2 times a week training;mean age subgroup showed a large effect,high heterogeneity,both groups showed large effects with significant differences.(2)The 505 change of direction test index was included in six studies and showed a medium effect,high heterogeneity,and no significant difference.Results of subgroup analysis: The training period subgroup showed a small effect with no heterogeneity,and both groups showed a moderate effect with no significant difference.The mean age subgroup showed a small effect,no heterogeneity,and no significant difference between the two groups.(3)Illinois test indexes were included in 7 studies and showed large effects,high heterogeneity,and significant differences in subgroup analysis:training period subgroup showed large effects,high heterogeneity,≤8weeks subgroup showed large effects,high heterogeneity,and significant differences;>8 weeks subgroup showed moderate effects,no heterogeneity and no significant differences.The training frequency subgroup showed a large effect with no heterogeneity,both subgroups showed high heterogeneity,the 1-2 training sessions per week subgroup showed a moderate effect with no significant difference,and the 3 or more training sessions per week subgroup showed a large effect with a significant difference.The mean age subgroup showed a medium effect with high heterogeneity,both subgroups showed high heterogeneity,the<14 years subgroup showed a medium effect size with no significant difference;the ≥14 years subgroup showed a large effect size with a significant difference.(4)Nebraska test indicators were included in five studies and showed moderate effects,high heterogeneity,and significant differences.(5)The AFL sensitivity test was included in7 studies with a moderate effect,high heterogeneity,and significant differences.Subgroup analysis results: training period subgroup showed a moderate effect,and high heterogeneity,and both groups showed high heterogeneity,and a significant difference,the ≤8 weeks subgroup showed a large effect,>8 weeks subgroup showed a moderate effect.The training frequency subgroup showed a medium effect,high heterogeneity,high heterogeneity in both groups,and significant difference,1-2 training sessions per week showed a medium effect,and≥3 training sessions per week showed a large effect.The mean age subgroup showed a medium effect with high heterogeneity,and both groups showed a medium effect with high heterogeneity and significant differences.The test-type subgroup showed a bell effect,high heterogeneity,and significant differences in both groups.The balled subgroup showed a medium effect and high heterogeneity;the unbilled subgroup showed a large effect and no heterogeneity.Conclusions:(1)SAQ training can improve the agility quality of soccer players;(2)SAQ training period should be selected at 8 weeks for the best effect;(3)SAQ training is more effective when the frequency of training is selected 3 times a week or more;(4)SAQ training has an improvement effect on the agility quality of soccer players of different age groups,and the performance improvement of soccer players with mean age >15 years is better than that of(5)The effect of SAQ training on sensitivity test without the ball is better than that of sensitivity test with the ball.
