在军校引入TMF训练方法可行性的研究     

杨祥红  王正磊  陈宏昱  窦文博 《当代体育科技》2020,(1):33-34

抗阻力训练是军校体能训练常用的训练方法,而训练至肌肉失败(TMF)作为抗阻力训练中一种新兴的训练方法,已经在健身领域引起越来越广泛的关注,并已经逐步应用于专业运动员训练中。TMF在军校这类对体能要求较高的机构内具有广阔的应用前景,但现阶段TMF在军校还未得到推广,大部分军校仍然沿用过去的传统抗阻力训练模式。本文从介绍抗阻力训练与TMF的相关概念出发,分析了TMF的作用机制,提出了在军校训练中引入TMF的可行训练项目。为了进一步研究TMF对于军校学员体能训练效果的影响,本文选取成绩相近的部分学员进行分组对照实验,运用统计学方法处理实验结果,从而证明了TMF对于学员体能具有明显提升作用,最后对本次研究工作进行了总结和展望。  相似文献

ABSTRACT

We performed a randomized, controlled trial to analyse the effects of resistance training (RT) on cognitive and physical function among older adults. Fifty participants (mean age 67 years, ~60% woman) were randomly assigned to an RT program or a control group. Participants allocated to RT performed three sets of 10-15RM in nine exercises, three times per week, for 12-weeks. Control group did not perform any exercise. Variables included cognitive (global and executive function) and physical function (gait, mobility and strength) outcomes. At completion of the intervention, RT was shown to have significantly mitigated the drop in selective attention and conflict resolution performance (Stroop test: -494.6; 95%CI: -883.1; ?106.1) and promoted a significant improvement in working memory (digit span forward: -0.6; 95%CI: ?1.0; ?0.1 and forward minus backward: -0.9; 95% CI: ?1.6; ?0.2) and verbal fluency (animal naming: +1.4, 95%CI 0.3, 2.5). No significant between-group differences were observed for other cognitive outcomes. Regarding physical function, at completion of the intervention, the RT group demonstrated improved fast-pace gait performance (?0.3; 95% CI: ?0.6; ?0.0) and 1-RM (+21.4 kg; 95%CI: 16.6; 26.2). No significant between-group differences were observed for other mobility-related outcomes. In conclusion, RT improves cognitive and physical function of older adults.  相似文献   

乡村政权建设视角下的国民党敌后游击战初探     

李春锋 《湖州职业技术学院学报》2011,(4):41-44

在中华民族的抗日战争中,国民党在组织正面战场的同时也开展了敌后游击战。国民党的敌后抗日游击战是以失败告终的。文章从乡村政权建设的视角分析了国民党敌后游击战走向失败的原因：国民党虽然在基层政府建构、基层政党建设、基层社团控制等方面加强了敌后乡村政权建设的力度,但其所采取的政策违背了敌后人民的利益,得不到敌后人民的支持,因而未能建立稳固的乡村政权。国民党乡村政权建设的失败是其敌后游击战难以长期坚持,最后走向失败的重要原因。  相似文献

“The Courage to Express Myself”: Muslim women's narrative of self-empowerment and personal development through university studies     

《International Journal of Educational Development》2015

The purpose of this research is to understand the process of self-empowerment that religious and non-religious Muslim women living in Israel experienced during their university studies. The principal results indicate a narrative of self-empowerment which develops through three stages: (a) awareness of gender regulation; (b) moral resistance; and (c) self-empowerment through university studies. Major study findings reveal that women do indeed undergo a deeply personal process of self-empowerment, which then encourages a growing awareness to their own inner strengths and ability to draw on such power in other aspects of life.  相似文献   

No effect of HMB or α-HICA supplementation on training-induced changes in body composition

β-hydroxy-β-methylbutyrate (calcium: HMB-Ca and free acid: HMB-FA) and α-hydroxyisocaproic acid (α-HICA) are leucine metabolites that have been proposed to improve body composition and strength when combined with resistance exercise training (RET). In this double-blind randomized controlled pragmatic trial, we evaluated the effects of off-the-shelf supplements: α-HICA, HMB-FA and HMB-Ca, on RET-induced changes in body composition and performance. Forty men were blocked randomized to receive α-HICA (n?=?10, fat-free mass [FFM]?=?62.0?±?7.1?kg), HMB-FA (n?=?11, FFM?=?62.7?±?10.5?kg), HMB-Ca (n?=?9, FFM?=?65.6?±?10.1?kg) or placebo (PLA; n?=?10, FFM?=?64.2?±?5.7?kg). The training protocol consisted of a whole-body resistance training routine, thrice weekly for 8 weeks. Body composition was assessed by dual-energy x-ray absorptiometry (DXA) and total body water (TBW) by whole-body bioimpedance spectroscopy (BIS), both at baseline and at the end of weeks 4 and 8. Time-dependent changes were observed for increase in trunk FFM (p?相似文献   

Light-load maximal lifting velocity full squat training program improves important physical and skill characteristics in futsal players     

Julio Torres-Torrelo  Juan José González-Badillo 《Journal of sports sciences》2017,35(10):967-975

This study aimed to compare the effect of 6 weeks of resistance training or combined resistance training and change of direction exercises on physical performance and motor skills in futsal players. Thirty-four futsal players were divided into full squat group (SG, n = 12), combined full squat and change of direction exercises group (S+CDG, n = 12) and control group (CG, n = 10). The resistance training for SG consisted of full squat with low load (~45–58% 1RM) and low volume (4–6 repetitions), whereas the S+CDG performed the same resistance training program combined with loaded change of direction. Sprint time in 10 and 20 m, change of direction test, countermovement vertical jump (CMJ) height, maximal strength and force–velocity relationship in full squat exercise, kicking speed ball (BS_mean) and repeated sprint ability (RSA_mean) were selected as testing variables. Both experimental groups showed significant improvements for CMJ, BS_mean and all strength parameters. Only SG resulted in significant sprint gains, whereas S+CDG also achieved significant improvements in RSA_mean. The CG remained unchanged after training period. No significant differences were found between both experimental groups. These findings suggest that only 12 sessions of either lightweight resistance training alone, lifting the load at maximal intended velocity or combined with change of direction exercises is enough to improve several physical and skills capacities critical to futsal performance in adult players.  相似文献   

Nuances about the Role and Impact of Affect in Inoculation     

《Communication monographs》2012,79(1):73-98

This study examined the role and impact of affect in resistance. A three-phase experiment was conducted. The results indicated that inoculation treatments conferred resistance and exerted nuanced outcomes involving cognitive and affective responses to counterarguments and affect. The investigation also compared the effectiveness of cognitive, affective-positive, and affective-negative treatments. The results revealed that affective-negative messages were superior in eliciting threat, issue involvement, and cognitive counterarguing output and in enhancing the cognitive content of associative networks.  相似文献   

People's media and communication rights in Indonesia and the Philippines1     

Ubonrat Siriyuvasak 《Inter-Asia Cultural Studies》2013,14(2):245-263

This article attempts to investigate the emerging people's media in relation to the development of communication rights in Indonesia and the Philippines. The thrust is to focus on how the Indonesian and Philippine press acquiesced to political and economic control by the governments of the dictatorial regime of President Soeharta and President Marcos. On the other contrary, we look at how people felt that communication rights are their basic rights and that freedom of thought and freedom of speech are essential for democratic rule. Their resistant to violence, imprisonment and murder carried out by state functionaries have brought new forms of media. These are people's media or radical and citizen media which empower as well as transform ‘passive citizens’ into ‘political actors’.  相似文献   

A Meta-Analysis of Research on Inoculation Theory     

《Communication monographs》2012,79(3):281-311

A meta-analysis of 54 cases testing the effectiveness of inoculation theory at conferring resistance and examining the mechanisms of the theory was conducted. The analyses revealed inoculation messages to be superior to both supportive messages and no-treatment controls at conferring resistance. Additionally, the results revealed refutational same and refutational different preemptions to be equally effective at reducing attitude change. However, the data were not consistent with some predictions made in narrative reviews of inoculation. No significant increase in resistance as a function of threat or involvement was found. Further, instead of a curvilinear effect for delay on resistance, the point estimates from our meta-analysis revealed equivalent resistance between immediate and moderate delays between inoculation and attack, with a decay in resistance after two weeks.  相似文献
