- Abstract: OBJECTIVE:This paper collects relevant literature on blood flow restriction training combined with resistance training,and analyzes the different effects of blood flow restriction training combined with resistance training on athletes'muscle-related indexes and specialized abilities in accordance with the paradigm of systematic evaluation and Meta-analysis,aiming to provide data support for athletes to utilize blood flow restriction training in their training practices. METHODS:Chinese and foreign databases(CNKI,WanFang,PubMed,Web of Science,SPORTDiscus)were searched to collect randomized controlled trials on the effects of blood flow restriction training combined with resistance training on limb circumference,muscle mass,muscle strength,and specialized ability of college athletes from January 1st,2000 to October 12th,2023.At least two researchers evaluated the quality of the included literature using the Cochrane Collaboration risk of bias assessment tools and criteria.Heterogeneity tests,data merging,subgroup analyses,forest plotting,and sensitivity analyses were performed using RevMan 5.4,and funnel plots with publication bias evaluation and sensitivity analyses were performed.The evaluation indexes were limb circumference,muscle thickness,muscle strength and specialized ability,and subgroup analyses were performed for different specialized athletic abilities. RESULTS:(1)A total of 18 randomized controlled trials with 403 subjects were included,and according to the Cochrane Collaboration's risk of bias assessment tool,the quality of literature in the included literature was grade A in 16 articles and grade B in 2 articles.(2)Comparing the effects of blood flow restriction training combined with resistance training and resistance training,there was no significant difference between the two groups in terms of limb circumference[standardized mean difference(SMD)=0.03,95%confidence interval:-0.16-0.21,P=0.78],and a significant difference between the two groups in terms of muscle thickness(SMD=0.14,95%CI:0.01-0.27,P=0.03)and muscle strength(SMD=0.37,95%CI:0.14-0.60,P=0.001).(3)Subgroup analyses of the indicators of specialized capacity indicated that there was high heterogeneity in the analyzed results of distance metrics(I2=73%)and time metrics(I2=55%),which was analyzed as a possible reason due to the differences in testing methods and assessment of metrics'significance in the studies;there was no heterogeneity(I2=0%)in the analyzed results of power metrics;blood flow restriction training combined with resistance training had a significant effect on distance metrics(P<0.01).(4)The results of the combined effect showed the effect of blood flow restriction training combined with resistance training vs.resistance training for specialized ability(P=0.41),suggesting that there is no significant effect of different training methods on specialized ability. CONCLUSION:Both blood flow restriction training combined with resistance training and resistance training can promote muscle thickness,muscle strength and specialized ability in college athletes.Meanwhile,blood flow restriction training combined with resistance training has a more significant effect on muscle thickness,muscle strength and some specialized abilities compared with resistance training.Therefore,blood flow restriction training can be scientifically and rationally integrated into specialized training,so as to achieve a better training effect by integrating the differentiated physiological stimuli to the muscles.However,due to the small number of included studies and other possible limitations,more high-quality,multi-sport type and sex randomized trials need to be included in the future to confirm this.
