This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.  相似文献   

The History of the South East Asian Peninsular Games,1959–1975     

Peng Han Lim  Mohd Salleh Aman 《国际体育史杂志》2016,33(5):545-568

After the Second World War the Southeast Asian countries of Burma (1948), Laos (1954), Cambodia (1955), South Vietnam (1955), Malaya (1957), and Singapore (1959) sought independence from the British, French and Japanese colonialists. The first post Second World War and post-colonial biannual multisport Southeast Asian Games was held in Bangkok in 1959 among these countries (and Thailand) although they were relatively poor developing countries. Referring to official reports of the eight bi-annual SEAP Games and other sources of information this research studies how the organization of the eight SEAP Games since 1959 contributed to the nation building process of each country and shaped the political landscape. This was carried out by creating a national identity through sports in each country as well as creating a sense of regional cooperation during periods of war, shifting boundaries and identities. This was done through rituals to legitimize newly ascended constitutional monarchies and heads of states, national flags and athletes' national identity during competition. The SEAP Games also gradually opened avenues for women's participation similar to female athletes in the Olympic Games. It also provided opportunities for promising athletes to shine, improve and compete at higher levels at the Asian and Olympic Games.  相似文献

为了智慧的生长——幼儿园课程的特质与旨归     

成尚荣 《幼儿教育》2006,(12)

幼儿园课程的特质与旨归是为儿童的智慧生长提供机会,让儿童学会用智慧统领知识.要提升幼儿园课程的实施智慧,就要对儿童进行再发现和再认识.儿童是幼儿园课程的永恒主语.幼儿园课程应该关注幼儿园中的儿童、教师心里的"儿童"和课程内容中隐藏的"儿童",让这三个"儿童"在幼儿园课程中相遇、交谈,共同建构幼儿园课程的实施情境,并在情境中实现共同发展.  相似文献   

Physical fitness normative values for 6–18-year-old Greek boys and girls,using the empirical distribution and the lambda,mu, and sigma statistical method     

Konstantinos D. Tambalis  Demosthenes B. Panagiotakos  Glykeria Psarra  Stelios Daskalakis  Stavros A. Kavouras  Nickos Geladas 《European Journal of Sport Science》2016,16(6):736-746

The aim of the this study was to establish age- and gender-specific physical fitness normative values and to compare percentiles and Z scores values in a large, nationwide sample of Greek children aged 6–18 years. From March 2014 to May 2014, a total of 424,328 boys and girls aged 6–18 years who attended school in Greece were enrolled. The studied sample was representative, in terms of age–sex distribution and geographical region. Physical fitness tests (i.e. 20?m shuttle run test (SRT), standing long jump, sit and reach, sit-ups, and 10?×?5?m SRT) were performed and used to calculate normative values, using the percentiles of the empirical distributions and the lambda, mu, and sigma statistical method. Normative values were presented as tabulated percentiles for five health-related fitness tests based on a large data set comprising 424,328 test performances. Boys typically scored higher than girls on cardiovascular endurance, muscular strength, muscular endurance, and speed/agility, but lower on flexibility (all p values <0.001). Older boys and girls had better performances than younger ones (p?相似文献   

Perceived health problems in swimmers according to the chemical treatment of water in swimming pools     

Álvaro Fernández-Luna  Pablo Burillo  José Luis Felipe  Julio del Corral  Jorge García-Unanue  Leonor Gallardo 《European Journal of Sport Science》2016,16(2):256-265

The objective of this study was to determine which chemical treatment used for disinfecting water in indoor swimming pools had the least impact on users' perceptions of health problems, and which generated the greatest satisfaction with the quality of the water. A survey on satisfaction and perceived health problems was given to 1001 users at 20 indoor swimming pools which used different water treatment methods [chlorine, bromine, ozone, ultraviolet lamps (UV) and salt electrolysis]. The findings suggest that there is a greater probability of perceived health problems, such as eye and skin irritation, respiratory problems and skin dryness, in swimming pools treated with chlorine than in swimming pools using other chemical treatment methods. Pools treated with bromine have similar, although slightly better, results. Other factors, such as age, gender, time of day of use (morning and afternoon) and type of user (competitive and recreational), can also affect the probability of suffering health problems. For all of the above, using combined treatment methods as ozone and UV, or salt electrolysis produces a lower probability of perceived health problems and greater satisfaction.  相似文献

幼儿研究性活动与教师角色的定位     

周香 《湖南师范大学教育科学学报》2006,5(1):121-123

幼儿研究性活动不同于一般的“主题“活动和中小学研究性学习,其自身的特征决定了幼儿教师应扮演多重角色,即正确教育理念的构建者,环境的创设者,幼儿活动的引导者、支持者、观察者,教育实践的研究者,活动方案的设计者.  相似文献
