目的:本研究旨在量化3-,4-,和职业成人足球的5天微循环,以及分析微循环长度对比赛后(MD-1)和比赛前一天(MD-1)产生的训练负荷的影响。
方法:这项研究涉及20名男性职业足球运动员,他们的外部和内部负荷被监测了整个赛季。训练曝光,覆盖的总距离,高速运行距离,冲刺距离(SD),个体SD高于个体最大速度的80%(D>80%),加速和减速的数量被量化,以及感知劳累的评分和感知劳累训练负荷的会话评分。
结果:微循环长度影响了大多数感兴趣的变量:高速运行距离(F=9.04,P<0.01),SD(F=13.90,P<0.01),D>80%(F=20.25,P<0.01),加速度(F=10.12,P<0.01),和减速(F=6.01,P<0.01)。训练日和微循环类型对SD有交互作用(F=5.46,P<0.01),D>80%(F=4.51,P<0.01),加速度(F=2.24,P=.06),和减速(F=3.91,P<0.01)。
结论:教练在训练建议中似乎受到较短微循环的影响,更喜欢在较短的微周期内减少肌肉影响的会议。与拥挤的夹具微循环的长度无关,当MD接近时,每日负荷似乎减少。
OBJECTIVE: This study aimed to quantify training and match-day (MD) load during 3-, 4-, and 5-day microcycles in professional adult football, as well as to analyze the effect of the microcycle length on training load produced the day after the match (MD + 1) and the day before the match (MD - 1).
METHODS: The study involved 20 male professional football players whose external and internal loads were monitored for a whole season. The training exposure, total distance covered, high-speed-running distance, sprint distance (SD), individual SD above 80% of the individual maximum velocity (D > 80%), and the number of accelerations and decelerations were quantified, as well as rating of perceived exertion and session rating of perceived exertion training load.
RESULTS: Microcycle length affected most of the variables of interest: high-speed-running distance (F = 9.04, P < .01), SD (F = 13.90, P < .01), D > 80% (F = 20.25, P < .01), accelerations (F = 10.12, P < .01), and decelerations (F = 6.01, P < .01). There was an interaction effect between the training day and microcycle type for SD (F = 5.46, P < .01), D > 80% (F = 4.51, P < .01), accelerations (F = 2.24, P = .06), and decelerations (F = 3.91, P < .01).
CONCLUSIONS: Coaches seem to be influenced by shorter microcycles in their training proposal, preferring sessions with a reduced muscle impact during shorter microcycles. Independent of the length of the congested fixture microcycle, the daily load seems to decrease when MD approaches.
