Fatigue Effects on the Timing Performance of Well-Practiced Subjects

Abstract

In an attempt to extend the laws of fatigue to the performance of highly practiced subjects, 24 college males were trained for four days (50 trials/day) on a coincident timing task prior to manipulation of the fatigue variable. On day 5, motor performance was immediately preceded by either local fatigue (static exercise), general fatigue (treadmill running), or no fatigue. Increased variable error was found for both local and general fatigue subjects as compared with controls on the first block of five trials following fatigue. However, by block 2 this difference had diminished. A constant error analysis on the first and second postfatigue trials revealed transitory overshooting of the criterion timing response for local fatigue subjects and undershooting for general fatigue subjects. The results suggested that local and general fatigue may alter the timing mechanism in different ways and that both are sources of at least transient decrements in the performance of well-practiced subjects.     

The ‘worn-out athlete’: A clinical approach to chronic fatigue in athletes

Chronic fatigue in the athletic population is a common but difficult diagnostic challenge for the sports physician. While a degree of fatigue may be normal for any athlete during periods of high-volume training, the clinician must be able to differentiate between this physiological fatigue and more prolonged, severe fatigue which may be due to a pathological condition. As chronic fatigue can be the presenting symptom of many curable and harmful diseases, medical conditions which cause chronic fatigue have to be excluded. The clinician must then be able to differentiate between chronic fatigue associated with training or chronic fatigue from other medical causes, and also between the chronic fatigue syndrome and the overtraining syndrome. Once the clinician has excluded all of the above medical conditions which cause chronic fatigue in athletes, a significant proportion of fatigued athletes remain without a diagnosis. Novel data indicate that skeletal muscle disorders may play a role in the development of symptoms experienced by the athlete with chronic fatigue. The histological findings from muscle biopsies of athletes suffering from the ‘fatigued athlete myopathic syndrome’ are presented. We have designed a clinical approach to the diagnosis and work-up of the athlete presenting with chronic fatigue. The strength of this approach is that it hinges on the participation of a multidisciplinary team in the diagnosis and management of the athlete with chronic fatigue. The athlete, coach, dietician, exercise physiologist and sport psychologist all play an important role in enabling the physician to make the correct diagnosis.

Isometric Knee Extension and Plantar Flexion Muscle Fatigue and Fiber Type Composition in Female Distance Runners

Abstract

Plantar flexion and knee extension fatigue patterns elicited by 25 serial isometric contractions were assessed on eight female distance runners. Fiber type composition of the vastus lateralis and gastrocnemius muscles was examined by a needle biopsy technique. Two different isometric exercise regimens were administered: 10-sec contractions separated by 5-sec intertrial rest (10:5) designed to elicit a rapid rate of fatigue, and 10-sec contractions separated by 20-sec intertrial rest (10:20) designed to induce less fatigue. No fatigue pattern was found for the 10:20 regimen which was consistent with previous data on male distance runners but unlike male power athletes who did exhibit significant fatigue. Significant fatigue decrements were found for the 10:5 knee extension (55.7%) and plantar flexion (75.8%) conditions. Fiber type composition and fatigue decrements did not correlate. Knee extension and plantar flexion maximum strength correlated significantly with the amount of fatigue induced with r's of .82 and .83, respectively. For each separate muscle group, maximum isometric strength was a better predictor of fatigability than fiber type composition. Even though differences in maximal strength and muscle mass existed between knee extension and plantar flexion muscle groups, elicited fatigue curves were similar in pattern differing only in absolute level. High versus low strength classification analysis showed similar knee extension but dissimilar plantar flexion fatigue patterns. Results suggest that the role of fiber type composition, muscle mass, and maximum strength level as they influence local muscular fatigue patterns must be elucidated for each muscle group separately.

运动性疲劳对横踢技术动作特征及其击打速度的影响研究

探究高水平跆拳道运动员身体出现不同量度的运动性疲劳时,横踢技术动作特征出现的差异及其对击打速度产生的影响程度。对20名跆拳道运动员采用Excalibur Sport cycle ergometer功率自行车进行诱导疲劳和YSI 1500 SPORT乳酸测试仪测定疲劳程度并划分为轻度、中度、重度三个量度;运用VICON Nexus三维系统捕捉横踢技术的运动轨迹,运用VICON Polygon软件将运动轨迹划分为启动、击打、回收三个时段进行分析。结果显示：启动时段三种疲劳的动作时间为：轻度疲劳0.25 s < 中度疲劳0.27 s < 重度疲劳0.29 s;击打时段的动作速度为：轻度疲劳12.20 m/s > 中度疲劳11.75 m/s > 重度疲劳10.64 m/s;横踢技术在回收时段的启动和加速过程中,三种类型之间的动作特征所表现出来的差异存在显著性（p<.05）。运动性疲劳的量度对横踢技术动作特征及其击打速度的影响较为显著。运动性疲劳的量度越大,技术动作的稳定性相对较差,鞭打动作形式也相对较差,对动作特征和击打速度的影响程度也越大;运动性疲劳的量度随着体内乳酸含量的变化而发生改变,乳酸峰值出现的时间节点是反映身体重度疲劳的时间节点,同时也是教练员合理调整技战术,通过消除疲劳的方式,减小对技术动作影响的重要节点。
