Objectives: Verify the validity of electrical bioimpedance (BIA) and the skinfold method in estimating the percentage of body fat (% BF) in middle-aged and elderly women, using dual emission X-ray absorptiometry (DXA) as a reference method. Material and methods: The sample consisted of 106 volunteers (middle age, n = 58 [51.3 ± 4.9 years] and elderly, n = 48 [67.2 ± 5.8 years]). The volunteers were submitted to anthropometric assessments and the % BF was subsequently calculated using the Jackson and Pollock 7 skinfold protocol (7SF). The % BF was also measured using BIA and DXA. Pearson’s correlation, Bland and Altman method, effect size and repeated-measure t-test were used to test the hypotheses. Results: Although there is a moderate positive relationship between the methods evaluated for middle-aged women (DXA vs 7SF, r = 0.67; DXA vs BIA, r = 0.62) and moderate to strong for the elderly (DXA vs 7SF, r = 0.57; DXA vs BIA, r = 0.75) (p ≤ 0.05 in all analyzes), the agreement between the methods was weak (limits of agreement > ± 3.5%). Additionally, when assessing the % BF mean using each method within the groups, it was observed that there was no significant difference between the estimates only between DXA and Pollock 7SF in the elderly group. Conclusion: Therefore, both the 7SF method and the BIA are not valid for estimating body fat in the sample evaluated. It is necessary to develop equations for specific skinfolds to estimate the % BF of middle-aged and elderly women and review the equations used by the BIA.
目的:以双发射x线吸收仪(DXA)作为参考方法，验证电生物阻抗法(BIA)和皮褶法估算中老年妇女体脂率(% BF)的有效性。材料与方法:共106例志愿者，其中中年58例[51.3±4.9岁]，老年48例[67.2±5.8岁]。志愿者接受人体测量评估，随后使用Jackson和Pollock 7皮肤褶协议(7SF)计算BF %。同时用BIA和DXA测定BF %。采用Pearson相关、Bland和Altman方法、效应大小和重复测量t检验对假设进行检验。结果:尽管对中年妇女评估的方法之间存在中度正相关(DXA vs 7SF, r = 0.67;DXA vs BIA, r = 0.62)，中重度老年人(DXA vs 7SF, r = 0.57;DXA vs BIA, r = 0.75)(所有分析均p≤0.05)，方法间一致性较弱(一致性限>±3.5%)。此外，当使用各组内每种方法评估% BF平均值时，观察到仅在老年组中DXA和Pollock 7SF之间的估计值之间没有显着差异。结论:因此，7SF法和BIA法都不能有效估计被评估样本的体脂。有必要建立特定皮肤褶皱的方程来估计中老年妇女的BF %，并回顾BIA使用的方程。

Introduction: Surface electromyography has been a technique used to describe muscle activity during running. However, there is little literature that analyses the behaviour of muscle coactivation in runners, describing the effect between two techniques associated with the initial contact, such as the use of rearfoot (RF) and forefoot (FF). Material and method: The purpose of this study was to compare muscle coactivation levels developed in the lower limb during two running techniques, FF vs RF. Fourteen amateur runners were evaluated (eight men, six women; age= 23.21 ± 3.58 years, mass= 63.89 ± 8.13 kg, height= 1.68 ± 0.08m). Surface electromyography was used to measure muscle activity during both running techniques evaluated on a treadmill, considering the muscle pairs: Rectus femoris- Biceps femoris (RFe-BF), Lateral Gastrocnemius–Tibialis Anterior (LG-TA), and Medial Gastrocnemius - Tibialis Anterior (MG-TA). These were calculated in three windows considering ten running cycles (0-5%, 80-100%, and 0-100%). To compare FF vs RF t-student test for paired data was used. Results: It was observed significant differences in the MG-TA pair (FF= 18.42 ± 11.84% vs RF = 39.05 ± 13.28%, p = 0.0018 during 0-5%, and RFe-BF pair (FF = 42.38 ± 18.11% vs RF = 28.37 ± 17.2%, p = 0.0331) during 80-100% of the race. Conclusion: Our findings show that the behaviour of muscle coactivation is different between FF vs RF techniques if we analyze little windows in the running cycle. This could be associated with an increase in the joint stability between these short intervals, represented in the initial and final regions of the running cycle.

Purpose: The aim of this study was to describe the anthropometrical and cardiovascular characteristics of short course trail runners and analyze the associations, if any, between both anthropometric and cardiovascular features of amateur trail runners. Material and method: Anthropometrical evaluation and an incremental maximum test with 10% of grade on a treadmill were performed on a group of 10 short distance amateur trail runners. Results: Significant negative correlations were found between the body max index (BMI) and the speed at VT1 (Vel VT1) (r = -0,95, p < 0,001), or the time to reach VT1 (r = -0,91, p = 0,002) and between the body fat percentage and the respiratory exchange ratio at VT2 (r = -0,80, p = 0,016) or the time to reach VT2 (r = -0,83, p = 0,01). Calf circumference was also found to be positively associated with oxygen consumption at VT1 (r = 0,74, p = 0,037), at VT2 (r = 0,90, p = 0,002) and with the maximal oxygen uptake (r = 0,85, p = 0,007). Conclusions: Results indicate that both body fat percentage and calf circumference could be related to the performance on an incremental test protocol with inclination in amateur trail runners.

Endurance exercise is a model of physiological integration. There is no other animal activity in which cardiovascular, respiratory, metabolic-endocrine and neuromuscular functions are activated at the same time. Even apparently, silent functions are essential during exercise (digestive, renal). During long-term exercise, the absorption of water and carbohydrates is a determining factor in performance. Kidney function plays a fundamental role in trying to preserve the hydro-electrolyte balance during exercise. In this work we present an integrative physiological perspective during dynamic exercise (mobilization of a large muscle mass with a low to moderate degree of strength development), both from the point of view of health and performance. The response of the heart rate in the first moments of exercise is a good example of the feedforward mechanism. Overall, the nervous system has two control mechanisms: feedforward and feedback. These depend on the central command, a more functional than anatomical entity. The feedforward system allows to immediately start the cardiovascular and respiratory systems. This mechanism is important because it activates the organism to overcome resting state. The feedback system is equally important because it allows the central command to receive the necessary information to “order” the appropriate response according to the intensity of the exercise. The information for retrocontrol comes from various receptors located in: the muscles, the respiratory system and the cardiovascular system. It is complex information that the central nervous system processes with exquisite precision, as can be seen in in endurance exercise.

Objective: To evaluate the morphological changes of Cuban super heavyweight boxers, more and less successful, through the period 1976-2014. Material and method: Thirty super heavy boxers, who were members of the Cuban national teams in the period 1976-2014, were compared; The strategy consisted of separating the group in the periods 1976-1989, 1990-1999, 2000-2009 and 2010-2014. Sixteen anthropometric dimensions were recorded (weight, height, sitting height, six skinfold thickness, five girths and two breadths), from which the body composition and the somatotype were obtained. The data were analyzed applying the Analysis of variance (ANOVA). The conglomerate analysis based on the Euclidean distance was used in order to evaluate the correspondence between physical development and sports performance. A discriminant analysis was carried out in order to analyze the contribution of the anthropometrical variables to the variance of different clusters. Results: Most of the anthropometric dimensions and indicators showed significant differences, having an impact on the increase in adiposity, body fat and endomorphy (p <0.05), as well as the decrease in the indicators dependent on height (p <0.05). The analysis by conglomerates, as well as the study of the Migratory Distances of the somatotype, showed that the Olympic medalist boxers differed in terms of the characteristics of body composition and in terms of the intensity of the somatotype changes in the period 1976-2014. Conclusions: The Cuban boxer of the super heavyweight category showed a wide range of morphological demands, but these were framed within the international trends of professional boxers. The morphological attributes of the Olympic medalists differed from each other, and from the rest of the boxers investigated over time. These results provide anthropometric data of high scientific value, both for selection and for medical control of training.

Introduction: The term “cross-education” describes the perfomance improvement, both in motor control and strength, of a limb after training the opposite. Despite its current interest, there is no consensus on many concepts of the transfer of a visuomotor skill. The aim of the present research was to review the current literature on the phenomenon of cross-education in visuomotor skills in order to determine the magnitude of transference and its relationships with the context of the intervention. Results: A literature search was conducted during December 2019 in the databases Pubmed, CINAHL, MEDLINE, Web of Science, SPORTdiscus and Scopus. The descriptors “Motor ability” and “Motor skill” were used, in addition to the keywords “Motor control”, “skill”, “Task”, “cross over effect”, “cross exercise”, “contralateral learning”, “inter limb transfer “,” cross transfer “,” cross education “. After applying the inclusion and exclusion criteria, a total of 19 articles were obtained for analysis. Of these articles, 12 are RCTs, 4 crossover clinical trial, 2 are non-randomized trials and only 1 lacks a control group. Most of the articles consist of a short-term intervention. Only 5 studies are of a duration of between 4 and 6 weeks. Conclusion: the cross-education phenomenon occurs in visuomotor skills. However, the magnitude of transference and its relation to the amount of learning of the trained member seems to be very variable depending on the context of the intervention. Likewise, the scarce consensus and the methodological differences in the studies make it difficult to draw firm conclusions about the effects of the context on the transference.
简介:“交叉训练”一词描述的是肢体在运动控制和力量训练后的表现改善。尽管它目前的兴趣，没有共识的许多概念转移的视觉运动技能。本研究的目的是回顾目前关于视觉运动技能交叉教育现象的文献，以确定移情的大小及其与干预环境的关系。结果:2019年12月在Pubmed、CINAHL、MEDLINE、Web of Science、SPORTdiscus和Scopus数据库中进行了文献检索。除“运动控制”、“技能”、“任务”、“交叉效应”、“交叉练习”、“对侧学习”、“肢体间迁移”、“交叉迁移”、“交叉教育”等关键词外，还使用了“运动能力”、“运动技能”等描述词。应用纳入和排除标准后，共获得19篇文章进行分析。在这些文章中，12篇是随机对照试验，4篇是交叉临床试验，2篇是非随机试验，只有1篇没有对照组。大多数文章都包含短期干预。只有5项研究的持续时间在4到6周之间。结论:视觉运动技能存在交叉教育现象。然而，迁移的大小及其与被训练成员的学习量的关系似乎是非常可变的，这取决于干预的背景。同样，研究中缺乏共识和方法上的差异使得很难得出关于环境对迁移的影响的确切结论。

Likewise, the scarce consensus and the methodological differences in the studies make it difficult to draw firm conclusions about the effects of the context on the transference.","PeriodicalId":38936,"journal":{"name":"Archivos de Medicina del Deporte","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46921542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this work is to analyze the reliability and validity of the new inertial measurement unit (IMU) PUSHTM Band 2.0 to measure barbell velocity. Six healthy males (24.83±3.71years; 69.88±8.36kg; 175.92±4.5cm) participated in this study and performed several sets on the bench press. Barbell concentric mean (MV) and peak (PV) velocity were recorded with a LT and the IMU. Pearson correlation coefficient shows a very high relationship for MV (r = 0.97; SEE: 0.08 m/s; 95%CI: 0.95-0.98; p< 0.001) and PV (r = 0.97; SEE: 0.13 m/s; 95%CI: 0.96-0.98; p< 0.001). There was a very high agreement for the values of MV and PV (MV: ICC = 0.945, CI = 0.834–0.974, α = 0.981; PV: ICC = 0.926, CI = 0.708–0.969, α = 0.977). Paired sample t-test revealed systematic bias for MV (p< 0.001; mean difference between instruments = 0.06 ± 0.09 m/s) and PV (p< 0.001; mean difference between instruments = 0.15 ± 0.18 m/s). Bland-Altman plots showed almost trivial and moderate relationships for MV (r2 = 0.1) and PV (r2 = 0.37). In conclusion, the PUSHTM Band 2.0 was proven to be a valid alternative for measuring barbell velocity in the bench press.
本工作的目的是分析新型惯性测量单元PUSHTM Band 2.0测量杠铃速度的可靠性和有效性。6名健康男性（24.83±3.71岁；69.88±8.36kg；175.92±4.5cm）参加了这项研究，并在卧推上进行了几组。用LT和IMU记录Barbell同心平均值（MV）和峰值（PV）速度。Pearson相关系数显示MV（r=0.97；SEE:0.08 m/s；95%CI:0.95-0.98；p<0.001）和PV（r=0.95；SEE:0.13 m/s；95%CI：0.96-0.98；p<0.001）的相关性非常高。MV和PV的值非常一致（MV:ICC=0.945，CI=0.834–0.974，α=0.981；PV:ICC=0.9 26，CI=0.708–0.969，α=0.9 77）。配对样本t检验显示MV的系统偏差（p<0.001；仪器之间的平均差=0.06±0.09 m/s）和PV（p<001；仪器之间平均差=0.15±0.18 m/s）。Bland-Altman图显示MV（r2=0.1）和PV（r2=0.37）之间几乎是琐碎和适度的关系。总之，PUSHTM Band 2.0被证明是测量台式压力机杠铃速度的有效替代方案。
