Acceptability and feasibility of public square dancing for community senior citizens with mild cognitive impairment and depressive symptoms:A pilot study

Objectives:To explore the acceptability and feasibility of public square dancing among community residents with mild cognitive impairment(MCI)and depressive symptoms.Methods:This mixed-method study consisted of a quantitative and a qualitative phase.From January to July 2018,a total of 241 community-dwelling senior citizens who complained of memory loss in one community in the Haidian District in Beijing were approached and screened,and 41 qualified for the study.Among them,35 senior citizens participated in the public square dancing intervention.By the end of the three-month follow-up,31 senior citizens completed the whole study.The Subjective Exercise Experience Scale(SEES)was used to survey senior citizens at the end of the three-month public square dancing intervention and follow-up to measure the participants’subjective exercise experience.Then 15 senior citizens were interviewed to collect attitudes,opinions,and suggestions related to the intervention.Results:During the intervention,90.6%of senior citizens met the requirement for defined hours.All senior citizens continued to dance at the three-month follow-up,and 32.3%met the requirement for defined hours.The scores of psychological well-being(11.03±2.82 vs.14.87±3.93,P<0.001)and fatigue(11.00[8.00,12.00]vs.14.00[9.00,18.00],P<0.001)increased at the end of the three-month follow-up.Qualitative research results extracted four major themes:increased confidence and a sense of accomplishment;easy to learn,close to real life,and sense of belonging;promotes physical and mental health;future expectations include music selection,reduced weather disruption,and self-organizing workouts.Conclusion:Public square dancing proved to be an acceptable,viable,and valuable intervention for MCI residents with depressive symptoms,which could be carried out by nursing staff in the community.Future studies should consider the appropriate population,intensity,and frequency of public square dancing and its effect on specific cognitive functions.

The effects of exercise on self-rated sleep among adults with chronic sleep complaints

Purpose： The purpose of this study was to evaluate whether and to what extent the observed effects on self-rated sleep in a previous study using a combined treatment program with physical exercise and sleep education can be attributed by the physical activity （PA） component. Methods： The present study reports supplementary analysis of an already described and published study. Data were provided by a nonclinical sample of 98 normal-active adults with chronic initiating and the maintaining of sleep complaints. The additional analysis included sleep log, exercise log, and daily pedometer data which were collected during a baseline week and 6-week of a combined intervention. Results： The results indicate that the number of steps （p -- 0.02） and the duration of PA （p = 0.01） is significantly related to the improvement in subjective sleep measures and therefore reveal an independent effect within this combined sleep program. Sleep diary data （recuperation of sleep, number of awakenings after sleep onset, and wake time after sleep onset time） improved significant （all p 〈 0.01） over the intervention program. About 50% of the participants stated that the PA had an effect on their improvement. Conclusion： Improvements on subjective sleep quality after a combined intervention cannot be attributed to the cognitive component alone, but PA has an independent effect. Adults with chronic sleep complaints benefit from exercise. Therefore structured PA should be implemented in any sleep management programs.

Comparing the effectiveness of karate and fitnes training on cognitive functioning in older adults——A randomized controlled trial

Background：Recent studies demonstrate a slowdown in deterioration of cognitive functioning in old age through aerobic training.There is evidence that the combination of aerobic,balance,and coordination exercises leads to an improvement or maintenance of cognitive functions.Such age-related exercises can especially be found in East Asian martial arts.The purpose of the current study is to verify whether karate training for older adults improves cognitive functioning and,if an improvement can be found,which cognitive field are influenced Methods：Eighty-nine older women and men（mean age：70 years） participated in this study.The participants were randomized into 2 intervention groups（karate group and fitnes group,duration of intervention：5 months） and a control group.All participants had to accomplish a cognitive test battery before and after the intervention.In a secondary study the karate group had an additional intervention for another 5 months.Results：The results show that there is a significan improvement in motor reactivity,stress tolerance,and divided attention only after the 5-month karate training period.Additionally,the results of the secondary study indicate further improvements after 10 months.Conclusion：The 5-month karate training can help to enhance attention,resilience,and motor reaction time,but a training period of 10 months is even more efficient

To investigate the effect of physical exercise and a healthy lifestyle

Focusing on human health in the 21st century is the common theme of the international community, with the continuous development of human society, the continuous improvement of quality of life, new health problems continue to appear, threatening human health, which has aroused great attention from the international community, it has taken the appropriate strategy, intervention effects of the disease on human health caused by the literature review, methods of induction and deduction in the current life of health, the impact of lifestyle on health, sports health effects were discussed with, so that people have a more clear understanding, of the health and quality of life of people.

武术运动中动作速度的初探

在武术运动中，动作速度的快慢是一个十分重要的问题。传统武术的理论中就有：“动如脱兔”、“拳似流星”、“刀光剑影”一快遮三丑”的说法。这些都是在强调武术动作中的“快”。“快”可以充分表现出武术运动所特有的气势和韵味，只有“快”才能做到动作的勇猛和刚健，也只有“快”才能使武术运动在人体锻炼中具有更大的价值。现在，除运动形式特殊的太极类的拳械套路要求速度缓慢、均匀外，几乎所有拳种都把“快”当作克敌制胜的“法宝”之一。因此，如何提高武术运动员的动作速度以及寻求适当的训练方法，就成了武术教练员们探讨和研究的重要课题。
