Comparative Efficacy Of Different Post-match Recovery Strategies On Lower Extremity In Amateur Basketball Players

Objective: The purpose of this study was to compare the efficacy of different post-match recovery strategies(Control,CON;Cold Water Immersion,CWI;Vibration Foam Rolling,VFR)on lower extremity in amateur basketball players following simulated basketball matches by determining the power,agility,dynamic balance and muscle activities before and after interventions.Methods: A total of 10 amateur basketball players participated in this study.Three post-match recovery strategies(12min meditation;12min CWI at 5℃ and 12 min VFR on gluteus maximus,quadriceps femoris,biceps femoris,and gastrocnemius at 30Hz)were applied on them after the simulated matches.Power,agility,dynamic balance and lower limb muscle activities were measured immediately after warm up,immediately after matches,immediately after interventions,1h after interventions and 24 h after interventions.The simulated basketball game includes 48 cycles of intermittent walking and running(1min per cycle).Jump height and root mean square(RMS)of muscles(gluteus maximus,quadriceps femoris,biceps femoris,gastrocnemius)were collected and calculated using Kistler force plate and Delsys electromyographic system.Reaction time and dynamic balance score were measured using Pavigym agility response system and Y balance test respectively.The SPSS 21.0 software was applied for data analysis using 3×5 two-way repeated measures ANOVA.Results: All parameters significantly decreased immediately after matches,and there is no difference between groups.Performance,1)Comparison between groups showed that,jump height and reaction time decreased significantly(jump height was different from the other two groups,and reaction time was different from VFR)while dynamic balance score was significantly improved(different from CON)immediately after CWI.1h after intervention,the jump height of CWI rose rapidly while VFR continued to recover(both different from CON).Jump height,reaction time and dynamic balance score of CWI continued to improve 24 h after intervention(jump height was different from the other two groups;reaction time and dynamic balance score were different from CON).2)Comparison within group showed that,CON only had a significant effect on agility recovery;although jump height and reaction time rapidly decreased while dynamic balance significantly increased immediately after CWI,all of them completely returned to prematch levels after 24h;VFR also has a significant effect on these parameters,and all of them basically recovered to pre-match level after 24 h.Muscle activation,1)Comparison between groups showed that,RMS of all muscles were significantly reduced immediately after CWI(different from CON and VFR);1h after CWI intervention,RMS of biceps femoris and gastrocnemius recovered rapidly(different from CON);RMS of all muscles continued to increase 24 h after CWI intervention(different from CON and VFR).2)Comparison within group showed that,although RMS of all muscles significantly dropped immediately after CWI,all of them eventually returned to pre-match levels after 24h;RMS of all muscles steadily increased after VFR,but only RMS of gluteus maximus basically recovered to pre-match level after 24 h.Conclusion and Implication: 1)All the three interventions have certain recovery effects on lower limb after matches,with CWI being the best and most lasting one;2)VFR has the best effect on lower limb recovery immediately after match;3)CWI could negatively affect power and agility immediately after the intervention,which may increase the injury risk of exercise;4)VFR is recommended if the players need to exercise immediately after matches,while both CWI and VFR can be used for recovery if it is for next-day training and matches(CWI is highly recommended).
