Mothers' Worries During Pregnancy: A Content Analysis of Reddit Posts

Qualitative investigations into maternal worries during pregnancy are limited. The aim of this study was to identify the content of women''s pregnancy-related worries by completing a content analysis of posts on Reddit. A total of 217 posts by 196 unique users were analyzed. Most worries related to infant factors (32.6%), individual factors (27.1%), and antenatal care factors, such as medical procedures (25.2%). The remaining worries related to situational factors (10.9%) and the partner relationship (4.3%). Although most fears related to fetal well-being, other concerns included problems with family members, women''s own mental health, and not being a “good mother.” These findings support calls for antenatal education to more adequately address women''s psychosocial concerns.

论身体运动与身体认知的具身性转向

认知科学的发展改变了人们传统的身体认知观念,具身认知的思想逐渐引起研究者的关注与重视,关于身体认知的研究开始朝向具身化方向转变。从人体运动场域的视角,探讨身体运动与身体认知具身性转向之间的关系及其相互影响。研究认为,身体运动在身体认知与被认知的过程中起到中介和调适作用,身体运动的方式可以映射出身体认知过程的具身性变化。身体运动可分为客观身体运动与现象身体运动两种类型,它们对身体认知的具身性转向起着不同的推动作用。身体运动特有的行为模式反映了身体认知与周围环境的关联性,身体运动的限制作用体现在身体认知表征的特性与范围方面,身体运动的分派特征对身体认知转向中的构成性角色具有证实作用,身体运动的调适功能是身体认知与具身行动之间协调性存在的重要保障。在身体运动对身体认知具身性转向的解释方面,要求身体运动应在身体认知的具身性转向中保持主动,重视身体经验的投射功能,关注身体运动的物理属性与运动方式的决定性作用。将身体运动的相关研究融入到具身认知的范畴,形成完整而有序的研究范式,将有助于解决身体认知研究领域中出现的系列问题。

运动对心肌、骨骼肌HSP70表达影响的研究进展

热休克蛋白的分子伴侣、抗氧化、抗损伤、协同免疫及抗细胞凋亡等多种功能,不仅生物界对它越来越关注,而且运动医学界的学者也对它产生了浓厚的兴趣。HSP70作为细胞应激蛋白,对不同强度与形式的运动,其反应和适应有很大差异,这为我们进一步认识运动规律,从而进行科学的体育锻炼和运动训练提供了新的思路和方法。     

Resultant muscle torque and electromyographic activity during high intensity elastic resistance and free weight exercises

Abstract

The purpose of this study was to quantify and compare Resultant Muscle Torque (RMT) and muscle activation (EMG) pattern, during resistance exercise comprising eight repetitions maximum (8 RM) biceps curl with elastic resistance and free weight exercise. Sixteen male and female recreationally active subjects completed 8 RM biceps curl by each of three modalities of resistance exercise: (i) dumbbell (DB), (ii) elastic tubing with original un-stretched length at the commencement of contraction (E0), and (iii) elastic tubing with 30% decrement of original length (E30) at the commencement of contraction. The magnitude of muscle activation, external force, acceleration as well as range of motion (ROM) were quantified and synchronised by specific software. The data were collected from all eight repetitions but the first (initial), the fifth (middle) and the eighth (last) repetitions were selected for further data analysis. Each selected repetition was partitioned into a concentric and eccentric phase and then each phase was further divided into three equal segments (3 concentric and 3 eccentric = 6 segments per repetition). The EMG and RMT data demonstrated a bell-shaped muscle activation and muscle torque production pattern for the three modes of exercise. The E30 resulted in 15.40% and 14.89% higher total EMG (µV) as well as 36.85% and 17.71% higher RMT (N · m) than E0 and DB, respectively (all P <0.05). These findings support the contention that an elastic resistance device (E30) has the capacity to provide an appropriate high resistance stimulus to meet the training requirement of elite athletes.     

关于体育健身和生命质量研究的视角、理论与方法

准确把握生命质量的内涵、实质和恰当的“视角”是体育领域开展生命质量研究的根本。为此,本研究运用文献资料、逻辑分析等方法梳理和分析了生命质量研究的产生根源、理论形成背景、研究视角、方法等历史发展轨迹,并从中发现提升体育生命质量是生命质量研究的根本目标;健身锻炼、体育重大事件、体育生活方式、体育社会参与等是体育研究生命质量可以借鉴的理论和视角;实验干预、优化技术等应用性方法是体育研究生命质量可以采用的前沿方法。     

Energy Cost of Rebound-Running

Using Sonstroem, Harlow, and Josephs' (1994) expanded version of the Exercise and Self-Esteem Model (EXSEM; Sonstroem &; Morgan, 1989), we explored how 9 older adults (6 women and 3 men, aged 65–72 years) involved in a resistance training program experienced and perceived changes in physical self-worth (i.e., improved strength, functional competency, physical condition, and body satisfaction). We conducted three in-depth interviews with each participant over the course of the program. In individual log books, participants recorded the weight lifted and the number of repetitions for each exercise. Our findings showed the course of changes in physical self-perceptions in these older adults and how actual individual changes in strength performance related to perceived changes in important psychological outcomes.
