Back pain (BP), a prominent problem for competitive athletes, is a primary reason for limitations in athletic performance and daily life restrictions. As studies on the relationship between psychological variables and BP in athletes are scarce, the aim of this study was to investigate stress and depression in competitive athletes with BP. In a cross-sectional design, data of 154 competitive athletes (51% female; M_age?=?18.81 years, SD_age?=?5.05 years) were collected, assessing Performance stress, Socio-emotional stress, Risk for depression and Psychological well-being and the two BP parameters BP Intensity and Disability. Two multiple linear regressions were conducted to predict (1) BP Intensity and (2) Disability from Performance stress, Socio-emotional stress, Risk for depression and Psychological well-being. Multiple linear regressions demonstrated that Performance stress (β?=?.21, p?=?.01) was the only significant predictor of BP Intensity (F_1,142?=?6.68, p?=?.01, R²?=?.05), whilst Risk for depression (β?=?.24, p?=?.01) was the only significant predictor of Disability (F_1,142?=?8.46, p?=?.01, R²?=?.06). Neither gender nor age explained a significant amount of variance in the models. Study results showed that, as in the general population, the variables stress and depression are related to BP in competitive athletes. In particular, BP intensity was found to be associated with stress and BP-related disability was associated with depression, whereas age and gender showed no association with the BP parameters. A longitudinal investigation is warranted to determine the direction of the observed relationships.  相似文献   

Mediating effects of motor performance,cardiorespiratory fitness,physical activity,and sedentary behaviour on the associations of adiposity and other cardiometabolic risk factors with academic achievement in children     

Eero A. Haapala  Niina Lintu  Aino-Maija Eloranta  Taisa Venäläinen  Anna-Maija Poikkeus  Timo Ahonen 《Journal of sports sciences》2018,36(20):2296-2303

We investigated the associations of cardiometabolic risk factors with academic achievement and whether motor performance, cardiorespiratory fitness, physical activity, or sedentary behaviour mediated these associations. Altogether 175 children 6–8 years-of-age participated in the study. We assessed body fat percentage (BF%), waist circumference, insulin, glucose, triglycerides, HDL cholesterol, and systolic and diastolic blood pressure, leptin, alanine aminotransferase, and gamma-glutamyltransferase (GGT). Reading fluency, reading comprehension, and arithmetic skills were assessed using standardized tests. Speed/agility, balance, and manual dexterity test results were used to calculate motor performance score and physical activity was assessed by combined heart rate and movement sensor and cardiorespiratory fitness by maximal cycle ergometer test. In boys, BF% was inversely associated with reading fluency (β = ?0.262, P = 0.007) and reading comprehension (β = ?0.216, P = 0.025). Motor performance mediated these associations. Leptin was inversely related to reading fluency (β = ?0.272, P = 0.006) and reading comprehension (β = ?0.287, P = 0.003). The inverse association of leptin with reading fluency was mediated by motor performance. In girls, GGT was inversely associated with reading fluency independent of confounders (β = ?0.325, P = 0.007). The inverse association of BF% with academic achievement among boys was largely explained by motor performance. Leptin in boys and GGT in girls were inversely associated with academic achievement independent of confounding factors.  相似文献   

Acute caffeine ingestion enhances strength performance and reduces perceived exertion and muscle pain perception during resistance exercise     

《European Journal of Sport Science》2013,13(4):392-399

Abstract

The efficacy of caffeine ingestion in enhancing aerobic performance is well established. However, despite suggestions that caffeine may enhance resistance exercise performance, research is equivocal on the effect of acute caffeine ingestion on resistance exercise performance. It has also been suggested that dampened perception of perceived exertion and pain perception might be an explanation for any possible enhancement of resistance exercise performance due to caffeine ingestion. Therefore, the aim of this study was to examine the acute effect of caffeine ingestion on repetitions to failure, rating of perceived exertion (RPE) and muscle pain perception during resistance exercise to failure. Eleven resistance trained individuals (9 males, 2 females, mean age±SD=26.4±6.4 years), took part in this double-blind, randomised cross-over experimental study whereby they ingested a caffeinated (5 mg kg^?1) or placebo solution 60 minutes before completing a bout of resistance exercise. Experimental conditions were separated by at least 48 hours. Resistance exercise sessions consisted of bench press, deadlift, prone row and back squat exercise to failure at an intensity of 60% 1 repetition maximum. Results indicated that participants completed significantly greater repetitions to failure, irrespective of exercise, in the presence of caffeine (p=0.0001). Mean±S.D of repetitions to failure was 19.6±3.7 and 18.5±4.1 in caffeine and placebo conditions, respectively. There were no differences in peak heart rate or peak blood lactate values across conditions (both p >0.05). RPE was significantly lower in the caffeine compared to the placebo condition (p=0.03) and was significantly higher during lower body exercises compared to upper body exercises irrespective of substance ingested (p=0.0001). For muscle pain perception, a significant condition by exercise interaction (p=0.027) revealed that muscle pain perception was lower in the caffeine condition, irrespective of exercise. With caffeine, pain perception was significantly higher in the deadlift and back squat compared to the bench press. However, with placebo, pain perception was significantly higher for the deadlift and back squat compared to the prone row only. Therefore, acute caffeine ingestion not only enhances resistance exercise performance to failure but also reduces perception of exertion and muscle pain.  相似文献   

Recurrent pain and discomfort in relation to fitness and physical activity among young school children     

《European Journal of Sport Science》2013,13(5):591-598

Abstract

As an increase in pain symptoms among children has been shown in the last decades, the aim of this study was to describe perceptions of recurrent pain, measured physical fitness and levels of reported physical activity (PA) in children, and to investigate if any associations between PA, fitness and recurrent pain could be identified. A school-based study comprised 206 Swedish children 8–12 years old, 114 boys, 92 girls. A questionnaire with questions about perceived pain, self-reported PA and lifestyle factors was used. Health-related fitness was assessed by 11 physical tests. A physical index was calculated from these tests as a z score. High physical index indicated high fitness and low physical index indicated low fitness. ANOVA test, chi-square test and logistic regression analysis were used to compare active and inactive children. The prevalence of one pain location (head, abdomen or back) was 26%, two 11% and three 4% (n=206). Female gender, living in single-parent families, low PA and low subjective health were associated with reported recurrent pain. Children reporting high levels of PA had high physical index and reported low prevalence of pain symptoms. The physical index and level of self-reported PA decreased gradually the more pain locations. Physically active children had higher fitness levels and reported less pain symptoms than inactive peers. Coping with pain is an integral part of PA, and active children learn to cope with unpleasant body sensations which together with high fitness may reduce the perception of pain.  相似文献

A linguistic dissociation in Williams syndrome: Good at gender agreement but poor at lexical retrieval     

Monnery  Sandrine  Seigneuric  Alix  Zagar  Daniel  Robichon  Fabrice 《Reading and writing》2002,15(5-6):589-612

Williams syndrome (WS) is a rareneuro-developmental disorder characterised byspared language in the face of serious deficitsin nonlinguistic cognitive abilities. Weconducted a study on ten WS individuals inwhich gender agreement and gender assignmentwere assessed by means of two tasks: gendercategorisation and gender concord. Subjectsperformed gender categorisation to real nounswhose gender was regular or exceptional giventheir ending, and to invented nouns which werecomposed of nonword or word stems and realword-endings. The same material was used in thegender concord task in which subjects had tomatch the items with the appropriate form ofthe article and the adjective carrying genderagreement. In the gender categorisation of realwords, WS were lower than controls but bothgroups demonstrated a similar sensitivity togender-ending regularities. In the gendercategorisation of nonwords, the results showeda clear dissociation. The WS subjects producedmore ending-consistent responses than thecontrols. Contrary to the controls, WS reliedheavily on the gender clue provided by theending even when the gender of the word evokedby the stem of the invented word was opposed tothat evoked by the ending. Participants with WSwere not influenced by the specific word evokedby the stem of the invented word. In the secondtask (concord task), the WS subjects performed well although lower than thecontrols. We concluded that the WS people werenot impaired in gender agreement which relieson syntactic rules and/or on the extraction ofregularities but experienced difficulties inretrieving lexical instances.  相似文献

黄庆平  王玲琳 《成人教育》2019,39(1):13-19

开放大学(电大)建设运行的学分银行有着其他学分银行不具备的时代特质,应是发展继续教育的重要抓手,然而它当前也正面临着如何认证非正式学习成果和如何建构转换标准体系这两个痛点。我国实施学分银行制度的时间较短,继续教育学分银行可借鉴国际继续教育领域学分银行制度的运行机制和功能设置。未来继续教育学分银行长期深耕于对工作和生活中获得的非正式学习成果的认证以及履行畅通不同类型教育之间转换通道的基础职责,从而为推进国家学分银行建设贡献改革经验实属必要。  相似文献   

The efficacy of `whole word' versus `analytic' reading instruction for children with Down syndrome     

Cupples  Linda  Iacono  Teresa 《Reading and writing》2002,15(5-6):549-574

An intervention study was conducted toinvestigate whether children with Down syndrome(DS) would benefit from an `analytic' approachto reading instruction, which encompassedexplicit training in phonological awareness.Participants were seven English-speakingchildren with DS aged 8;6 (years;months) to11;1, who demonstrated little or nononword-reading ability prior to intervention.The children received weekly instruction (forsix weeks) in reading aloud 30 regularly speltmonosyllables (e.g., ten, bake) using an`analytic' approach, in which words werelearned by combining onsets with rimes (fourchildren), or a `whole-word' approach (threechildren). Participants' oral reading wasassessed pre- and post-intervention using areading test comprising the 30 trained wordsand 30 untrained (generalisation) words. Mostchildren (six out of seven) read more trainingwords correctly after intervention than before,with significant improvement shown by fourchildren (two trained analytically, and twotrained with whole words). More importantly,reading of generalisation words improvedsignificantly in only three children, all ofwhom had received analytic training. It wasconcluded that children with DS benefit from ananalytic approach to reading instruction, eventhough their auditory-verbal memory (assessedusing digit span) is poor.  相似文献
