Introduction: In the knee extensors, the time to fatigue for intermittent isometric contractions can be increased by caffeine. Fatigue is muscle length dependent. Aim: We examined the effect of caffeine on fatigue of knee extensors at two joint angles. Methods: Ten male subjects (24±3 yr, 177±5 cm, 75±6 kg) with low caffeine intake (<200 mg·wk -1 ) volunteered. Study design was double-blind and counter-balanced. Subjects were administered caffeine (6 mg·kg -1 ) added to a non-caloric beverage or placebo, 1 hr before testing. Maximal voluntary isometric torque (MVIT) and intermittent contractions at 50%MVIT (15 s contraction, 5 s rest) were performed at knee angles of 30° and 90° (short and long length) until exhaustion. Fatigue was quantified by measurement of the MVIT 20 s post exhaustion. Surface EMG of m.vastus lateralis was analysed for root mean square (RMS). Data were analysed with 2-way ANOVA and paired t-tests with significance set at P<0.05. Results: MVIT values were similar for caffeine and placebo at both knee angles. Time to fatigue was higher at 30° for both conditions. Caffeine increased the time to fatigue, being equal by 15% (30°) and 13% (90°). The fatigue index was similar for both conditions and knee angles. Changes in RMS were similar for both conditions and knee angles [e.g. 30°: 154±14% (caffeine), 154±16% (placebo)]. Conclusions: Caffeine enhanced the time to fatigue during submaximal intermittent isometric contractions at different knee angles. However, potential mechanism(s) for the enhanced time to fatigue by caffeine do not seem to be muscle length dependent.
在膝关节伸肌中,咖啡因可以增加间歇等长收缩的疲劳时间。疲劳与肌肉长度有关。目的:观察咖啡因对膝关节两个关节角伸肌疲劳的影响。方法:10名男性志愿者(24±3岁,177±5 cm, 75±6 kg),低咖啡因摄入量(<200 mg·周-1)。研究设计为双盲和平衡。受试者在测试前1小时在无热量饮料或安慰剂中添加咖啡因(6 mg·kg -1)。最大自主等距扭矩(MVIT)和50%MVIT的间歇收缩(收缩15秒,休息5秒),膝关节角度为30°和90°(短长度和长长度),直到筋疲力尽。疲劳通过测量疲劳后20秒的MVIT来量化。分析股外侧肌表面肌电图的均方根(RMS)。资料分析采用双因素方差分析和配对t检验,P<0.05。结果:咖啡因组和安慰剂组在两个膝关节角度的MVIT值相似。两种情况下,30°时的疲劳时间都更长。咖啡因增加了疲劳时间,分别增加了15%(30°)和13%(90°)。两种情况和膝关节角度下的疲劳指数相似。两种情况和膝关节角度的RMS变化相似[例如30°:154±14%(咖啡因),154±16%(安慰剂)]。结论:咖啡因增加了不同膝关节角度次极大间歇等距收缩时的疲劳时间。然而,咖啡因延长疲劳时间的潜在机制似乎与肌肉长度无关。

Purpose: to analyze the physical activity (PA) level of pregnant women (PW) according to their gestational trimester and to evaluate multiple measurements of PA. Methods: 122 PW, 26.5 ± 5.5 years old, and between the 4th and 37th week of pregnancy participated. PA was evaluated by levels of frequency and intensity, duration of walking, and moderate and vigorous PA; and based on the calculation in METs, determined by IPAQ and a pedometer. Data analysis was done by the Kruskall-Wallis, significance level of P<.05. Results: a significant decrease was found in the duration of moderate PA in the second-trimester group when compared to the duration of the first and the third trimester groups. There were no differences in walking (4.8 days/week) and moderate PA frequency (3.1 days/week) on average across trimesters. When considering the weekly number of steps, PW had in the first trimester taken an average of 10,789.0 ± 5,676.8 steps, in the second trimester 6,812.1 ± 4,092.4 steps, and in the third trimester 6,746.8 ± 3,572.0 steps. There was no significant difference in the weekly total number of steps between trimesters. Conclusion: the PA level of PW, using IPAQ or pedometer, was similar regardless of the trimester of the pregnancy.

The aim of the study was to compare the effects of high and low concentration carbohydrate (CHO) solutions on the endurance performance of recreational, male soccer players consumed prior to and during intense, intermittent exercise. Methods: Seven participants consumed four different fluids using a randomised double blind procedure, an 8% carbohydrate electrolyte solution (2.5% galactose and 5.5% glucose polymer) (8% CES), a 2.5% carbohydrate (2.5% galactose) electrolyte solution (2.5% CES), an electrolyte solution (E) and water (W). A further three participants acted as controls by consuming E only on four occasions. We used the Loughborough Intermittent Shuttle Test (LIST) to simulate the intense, intermittent nature of a soccer match. The LIST protocol consists of two parts: Part A required walking, jogging and sprinting, utilising a 20 m shuttle procedure, for 75 min, recovering for 3 min every 15 min. Part B required participants to perform intermittent running to exhaustion, alternating between 55% and 95% of their predicted maximal oxygen uptake. Each beverage was administered immediately prior to exercise (5 ml · kg-1) and every 15 min thereafter (2 ml · kg-1) until the conclusion of Part A. Results: The performance run times for Part B (mean ± SD) were 16.3 ± 1.5 min (8% CES), 11.1 ± 1.2 min (2.5% CES), 10.0 ± 1.0 min (E) and 9.3 ± 0.9 min (W). The 8% CES beverage produced a significantly greater time to exhaustion (Part B) than the other drinks (5.0 ± 1.5 min, P<0.05). Conclusions: A high CHO concentration formulation (8% CES) is associated with a significant increase in endurance performance during intense, intermittent exercise in recreational, male soccer players.

Introduction: Although a considerable amount of research is available describing the physiological characteristics of competitive adolescent and senior level cyclists, research describing the same characteristics in master level cyclists is rare. Aim of this study was to compare cardiorespiratory power and force-velocity characteristics between two groups, one of master and one of senior level cyclists in an attempt to examine the effect of aging on these parameters. Methods: Eighteen master (43.25±5.37 y) and 13 senior level male road cyclists (28.78±4.95 y) were examined for anthropometric characteristics, body composition, and they performed the anaerobic force-velocity test and a graded exercise test to determine maximal oxygen consumption and anaerobic threshold. Results: Maximal heart rate (accordingly 176.9±13.8 bpm vs. 189.1±8.3 bpm) and heart rate at anaerobic threshold (157±13.9 bpm vs. 170.5±8.3 bpm) were the only parameters that differed significantly (P<0.001). Conclusions: Based on these results, it was concluded that optimal training could attenuate the decline of physiological parameters in cyclists until the beginning of the 5 th decade of human life. In addition, considering the variability of heart rate values (either maximal or at anaerobic threshold), i.e. wider range of scores in master than in senior level participants, it was suggested the need for individualized data, especially in master level road cyclists.
虽然有相当多的研究描述了竞技青少年和高级水平自行车运动员的生理特征,但描述大师级自行车运动员相同特征的研究很少。本研究的目的是比较两组,一组高手和一组高级水平自行车手的心肺功能和力-速度特征,试图探讨年龄对这些参数的影响。方法:对18名男子公路自行车运动员(43.25±5.37 y)和13名男子公路自行车运动员(28.78±4.95 y)进行人体测量、身体组成、无氧力-速度测试和分级运动测试,测定最大耗氧量和无氧阈值。结果:最大心率(176.9±13.8 bpm vs. 189.1±8.3 bpm)和无氧阈心率(157±13.9 bpm vs. 170.5±8.3 bpm)是仅有的差异显著的参数(P<0.001)。结论:基于这些结果,我们得出结论,最佳训练可以减缓骑自行车者生理参数的下降,直到人类生命的第50个十年开始。此外,考虑到心率值(最大或无氧阈值)的可变性,即与高级水平的参与者相比,高级水平的得分范围更大,建议需要个性化的数据,特别是在高级水平的公路自行车运动员中。

Introduction: Active video games have been purported to offer an alternative means by which children can be physically active but few data have examined this issue in ecologically valid settings. This study sought to assess physical activity levels during active videogame play and compare this to ‘free play’ associated with recess activity in a sample of British primary school children. Methods: Forty children (ages 10-11, 20 boys, 20 girls) from central England were randomly selected to participate in a 6 week, lunchbreak based, active video gaming intervention (n=20) or act as controls (n=20). Repeated measures analysis of covariance (controlling for body mass index) was used to examine any differences in physical activity, determined by pedometry and heart rate monitoring. Results: Children in the intervention accumulated significantly greater steps/min than controls during the first week of the intervention. The steps/min values were not significantly different at the mid point or during the last week of the assessment period. Irrespective of time point, children engaging in active video game play spent a lesser percentage of time engaged in MVPA than controls undertaking ‘traditional’ recess activity. Conclusion: Active video game physical activity using the Gamercize power stepper appears to be similar to physical activity levels during traditional school lunchbreak over a 6 week period. Active videogaming may therefore provide an alternative means to engage children in physical activity in the school setting.
