Abstract

BACKGROUND: Prolonged fatigue effects may be a concern after futsal matches mainly because of the actions performed by futsal players (e.g., sprinting, jumping) that usually involve the stretch-shortening cycle (SSC). However, there no studies analyzed the prolonged effects of futsal-specific fatigue and how futsal players can recover from performance tasks. OBJECTIVE: To analyze the acute and prolonged effects of a protocol that simulates specific physical demands of futsal on countermovement-jump, sprint performance, muscle strength and muscle soreness. METHODS: Fifteen amateur futsal male athletes (18.3 ± 3.8 years) performed a futsal intermittent running protocol (FIRP) and were assessed for (moment production, sprint and jumping performance and muscle soreness) at pre, during half-time, immediately after, post 24 and 48 hours after the FIRP. Analysis of variance (repeated measures) was used to compare variable means over time. RESULTS: The main results indicated a decrement in the CMJ height (p= 0.03) and an increase of 10 m and 20 m sprint times (p= 0.01–p< 0.01, respectively) during half-time and the post FIRP. There was a decrement in eccentric peak moment of the knee extensors (p= 0.02) and flexors (p< 0.01) until 48h post protocol and a decrement in concentric peak moment of the flexors (p< 0.01) post protocol. Athletes reported muscle soreness in the hamstrings (p= 0.03) post and 24 h after the FIRP. CONCLUSION: FIRP induced acute effects in the jump and sprint performances only. On the other hand, the knee moment production capability (mainly eccentric) suffered acute and also prolonged effects of the FIRP accompanied by delayed muscle soreness in the hamstring muscles.

五人制足球比赛模拟身体需求对下肢肌肉力量、短跑成绩和肌肉酸痛的急性和长期影响
背景:五人制足球比赛后,疲劳效应可能会延长,这主要是因为五人制足球运动员的动作(如短跑、跳跃)通常涉及拉伸-缩短周期(SSC)。然而,没有研究分析五人制足球特有疲劳的长期影响以及五人制足球运动员如何从表演任务中恢复。目的:分析模拟五人制足球特定身体需求的方案对反动作跳跃、短跑表现、肌肉力量和肌肉酸痛的急性和长期影响。方法:15名业余五人制足球男子运动员(18.3±3.8岁)进行五人制足球间歇跑(FIRP),并在FIRP前、中、后、24小时和48小时评估(力矩产生、短跑和跳跃表现以及肌肉酸痛)。方差分析(重复测量)用于比较随时间变化的平均值。结果:主要结果表明,在半场和FIRP后,CMJ高度下降(p=0.03),10米和20米冲刺时间增加(分别为p=0.01–p<0.01)。直到方案后48小时,膝伸肌和屈肌的偏心峰值力矩(p=0.02)和屈肌(p<0.01)减少,而屈肌的同心峰值力矩(p<0.01)在方案后减少。运动员在FIRP后24小时报告了腘绳肌酸痛(p=0.03)。结论:FIRP只对跳跃和短跑表现产生急性影响。另一方面,膝关节力矩产生能力(主要是偏心)受到FIRP的急性和长期影响,并伴有腘绳肌的延迟性肌肉酸痛。

期刊介绍: Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology. IES publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research. The journal welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
