Dear editor:We sincerely thank Matthew *** for his insightful commentary1 on our recent publication in the Journal of Sport and Health Science.2 Clarkson's pioneering work in the development and application of blood flow restriction (BFR) exercise protocols has undeniably laid the groundwork for subsequent investigations in this field,including our own.(3-6)His commentary not only highlights the relevance and timeliness of our study but also offers valuable perspectives on refining safety considerations for intradialytic BFR exercise among hemodialysis patients.

资源分配到生殖过程涉及到生态和进化因素,可能会减少植物的营养生长。这种相互关系在自然界中不容易观察到,因为有许多参数可以限制生殖结构的产生或生物量的增加。我们将香椿(Cedrela odorata L.,楝科)在里约热内卢州大西洋森林中的树木年轮宽度与超年生殖行为相关联。总体而言,生殖结构的发育发生在湿润的年份,在生长季初期没有出现水分亏缺。然而,在这些年份,树木年轮宽度较小。这些结果可能与树木年轮宽度与当地气候之间缺乏相关性有关。因此,我们强调在径向生长研究中纳入生殖数据的重要性,以扩大对热带森林生长变异性的理解。

Non-exhaustive double effort test is reliable and estimates the firs ventilatory threshold intensity in running exercise

Journal of Sport and Health Science 2018年第2期7卷 197-203页

作者： Lucas Dantas Maia Forte Fúlvia Barros Manchado-Gobatto Roberta Cunha Matheus rodrigues Maria Ceclia Gallani claudio Alexandre Gobatto School of Applied Science University of Campinas School of Nursing University of Campinas Faculty of Nursing Laval University

Purpose: The present study aimed to investigate the reliability of the non-exhaustive double effort(NEDE) test in running exercise and its associations with the ventilatory thresholds(VT_1 and VT_2) and the maximal lactate steady state(MLSS).Methods: Ten healthy male adults(age: 23 ± 4 years, height: 176.6 ± 6.4 cm, body mass: 76.6 ± 10.7 kg) performed 4 procedures:(1) a ramp test for VT_1 and VT_2 determinations measured by ratio of expired ventilation to O_2 uptake(VE/VO_2) and expired ventilation to CO_2 output(VE/VCO_2) equivalents, respectively;(2) the NEDE test measured by blood lactate concentration(NEDE_(LAC)) and heart rate responses(NEDE_(HR));(3) a retest of NEDE for reliability analysis; and(4) continuous efforts to determine the MLSS intensity. The NEDE test consisted of4 sessions at different running intensities. Each session was characterized by double efforts at the same running velocity(E1 and E2, 180 s), separated by a passive recovery period(90 s rest). LAC and HR values after E1 and E2(in 4 sessions) were used to estimate the intensity equivalent to"null delta" by linear fit. This parameter represents, theoretically, the intensity equivalent to maximal aerobic ***: The intraclass correlation coefficient indicated significant reliability for NEDE_(LAC)(0.93) and NEDE_(HR)(0.79)(both p < 0.05). There were significant correlations, no differences, and strong agreement with the intensities predicted by NEDE_(LAC)(10.1 ± 1.9 km/h) and NEDE_(HR)(9.8 ± 2.0 km/h) to VT_1(10.2 ± 1.1 km/h). In addition, despite significantly lower MLSS intensity(12.2 ± 1.2 km/h), NEDE_(LAC) and NEDE_(HR) intensities were highly correlated with this parameter(0.90 and 0.88, respectively).Conclusion: The NEDE test applied to running exercise is reliable and estimates the VT_1 intensity. Additionally, NEDE intensities were lower but still correlated with VT_2 and MLSS.

Freud’s Theory and the Group Mind Theory:Formulations

引用

Open Journal of Medical Psychology 2014年第1期3卷 24-35页

作者： claudio Garcia Capitao Sao Francisco University Rua Alexandre Rodrigues BarbosaItatibaBrazil

This study aimed to reconsider some concepts of the psychoanalytic theory on group mind. Group psychology is concerned with the individual man as a member of a race, nation, caste, profession, or an institution, or as a component of a crowd of people that has been organized into a group at some particular time, for some specific purpose. Group psychology embraces an immense number of separate issues and offers investigators with countless problems, which have hitherto not even been properly distinguished from one another. Reflections presented in this paper were particularly inspired by Freud’s work on Group psychology and analysis of the ego and approaches to the chaos theory, especially, the fact that groups emerge as systems that exhibit unstable, aperiodic and highly complex behavior, with a tendency to self-organization.
