Analysis of Peak Locomotor Demands in Professional Female Soccer Players:An Approach Based on Position and the Day of the MicrocycleOACSCD

Purpose The aim of this study was to examine the peak locomotor demands of match play and determine if these situations are replicated in training,and analyze their dynamics throughout the competitive microcycle in professional female soccer players based on their positions.Methods Measurements such as distance covered(DIS),high-speed running distance(HSRD),sprint distance(SPD),accelerating distance(ACCDIS),decelerating distance(DECDIS),and high metabolic load distance(HMLD)were registered during 1,3,5 and 10-min peak locomotor in both competitive matches(MD)and training sessions(ranked based on the number of days remaining until the next match,namely MD-4,MD-3,MD-2,and MD-1)within a competitive mesocycle.Results Central defenders were found to cover significantly less HMLD than full-backs and forwards,regardless of the time frame,as well as less HMLD than center midfielders in the 3,5 and 10-min time frames.Only in MD-3 did players exhibit a similar HMLD to MD,regardless of the analyzed time frame.Players covered significantly less HSRD and SPD in MD-2 and MD-1 compared to MD-3,and less HSRD in MD-4 compared to MD-3.Additionally,HSRD and SPD were significantly higher in MD-4 than in MD-1.There were no significant differences in HSRD or SPD relative to match play workload observed between positions within the same training session.Conclusion The microcycle showed a non-linear training load,with higher external loads in central sessions(e.g.,MD-3)and tapering strategies at the end of the microcycle in peak locomotor demands.
