摘要
目的:脑力疲劳(mentalfatigue,MF)是由长时间较高强度认知活动导致的一种精神生物学状态,并可表现为主观上感到疲惫和缺乏能量。明确MF与足球运动员竞技能力的关系对于其更好地训练、比赛等意义重大。因此,研究旨在探讨MF对足球运动员灵敏(AGT)、下肢爆发力(CMJ)和平衡(YBT)的影响。方法:采用随机交叉对照试验设计,18名男性业余足球运动员[年龄(20.72±2.42)岁,身高(177.08±5.99)cm,体质量(71.16±9.55)kg,体脂率16.3%±4.3%,训练年限(6.61±3.91)年]参与45 min的Stroop任务(MF组)和中性视频观看任务(对照组),时间间隔≥48 h,并于每次任务后参加灵敏、下肢爆发力和平衡3项能力测试,记录受试者任务前后的VAS-MF和VAS-MO指标以及运动能力测试过程中的RPE指标。结果:MF组与对照组干预前VAS-MF无显著差异(P=0.281),干预后VAS-MF(P=0.002)和干预前后VAS-MF差值(P=0.001)均显著高于对照组;MF组干预前(P=0.385)、干预后(P=0.288)的VAS-MO以及任务前后VAS-MO差值(P=0.726)均与对照组无显著差异;MF组3项运动能力的测试成绩(AGT:t=0.764,P=0.455,d=0.18,95%CI=-0.288~0.643;CMJ:t=0.116,P=0.909,d=-0.027,95%CI=-0.489~0.435;YBT-左:t=0.547,P=0.591,d=0.129,95%CI=-0.337~0.591;YBT-右:t=1.078,P=0.296,d=0.254,95%CI=-0.219~0.720)均与对照组无显著差异,AGT(P=0.307)、CMJ(P=0.083)、YBT(P=0.088)测试结束后RPE也与对照组无显著差异。结论:MF对足球运动员灵敏、下肢爆发力和平衡3项能力无显著影响。
Objective:Mental fatigue(MF)is a psychobiological state caused by prolonged periods of demanding cognitive activity and characterized by subjective feelings of“tiredness”and“lack of energy”.To clarify the effects of MF on different physical ability in soccer players has great significance for them to conduct training and competition.Therefore,the purpose of this study is to investigate the effects of mental fatigue on agility(AGT),explosive strength of low-limb(CMJ)and balance(YBT)in soccer players.Methods:18 male amateur soccer players[age:(20.72±2.42)yrs,height:(177.08±5.99)cm,body mass:(71.16±9.55)kg,body fat percentage:16.3%±4.3%,training experience:(6.61±3.91)yrs]participated a randomized crossover trial,and were asked to finish both 45 min Stroop task(MF group)and 45 min emotionally neutral video watching task(control group)with an interval≥48 h.After each task,participants were instructed to participated in three tests for agility,low-limb explosive strength and balance assessment.VAS-MF and VAS-MO pre-post treatment and RPE after each test were collected for analysis.Results:The values of VAS-MF at pre-treatment in MF group were similar to control group(P=0.281),while VAS-MF at post-treatment(P=0.002)and the changes of VAS-MF pre-and post-treatment in MF group(P=0.001)were all higher than control group.The values of VAS-MO at pre-treatment,post-treatment and the changes of VAS-MO in MF group were similar to control group(P=0.385,0.288 and 0.726).The differences of performance of AGT(t=0.764,P=0.455,d=0.18,95%CI=-0.288~0.643),CMJ(t=0.116,P=0.909,d=-0.027,95%CI=-0.489~0.435)and YBT(YBT-Left:t=0.547,P=0.591,d=0.129,95%CI=-0.337~0.591;YBT-Right:t=1.078,P=0.296,d=0.254,95%CI=-0.219~0.720)were not significant between MF group and control group.The differences of RPE of AGT(P=0.307),CMJ(P=0.083)and YBT(P=0.088)were not significant between MF group and control group.Conclusions:Mental fatigue doesn’t impair agility,explosive strength of low-limb and balance performance in soccer players.
