Abstract

Third and fourth grade boys (n = 422) and girls (n = 390) in four Texas elementary schools reported their participation in moderate to vigorous physical activities (MVPAs) over a 3-day period. Students were surveyed during class on successive days. On a subsample (n = 44), the agreement between reported and observed physical activities during physical education or recess was 86.3%. Running, walking fast, games and sports, and bicycling accounted for 70% of Total MVPAs. Of Total MVPAs reported, 47.0% for boys and 44.6% for girls were 10 min or longer in duration (LMVPA). The average number of LMVPAs per day was 1.7 for both boys and girls. Students reported significantly more occurrences of LMVPAs out of school than during school. Significant interaction between grade and gender indicated that third grade boys reported more Total MVPAs and LMVPAs than third grade girls, but fourth grade boys reported fewer Total MVPAs and LMVPAs than fourth grade girls. During the 3-day reporting period, 12.3% of boys and 13.3% of girls reported no LMVPAs, and 35.6% of boys and girls reported fewer than one LMVPAs per day. While the majority of children reported obtaining at least some activity daily, a substantial proportion of children in this sample reported fewer than one LMVPA daily, indicating that many children may not be obtaining adequate amounts of physical activity.  相似文献

The purpose of this study was to provide three construct validity evidence for using fitness center attendance electronic records to objectively assess the frequency of leisure-time physical activity among adults. One hundred members of a fitness center (45 women and 55 men; aged 18 to 64 years) completed a self-report leisure-time physical activity questionnaire. The theory of planned behavior constructs (e.g., intention and perceived behavioral control), VO2max, and % BF were assessed. Fitness center attendance electronic records were expressed as the weekly mean number of mandatory check-in records retrieved from the fitness center's electronic database over a 12-week period prior to participant's physical fitness evaluation. A continuous (frequency) and categorical (“adherent” versus “non-adherent”) scores were computed. Results indicated that perceived behavioral control was associated with fitness center attendance electronic records and mediated the fitness center attendance electronic records–intention relationship. Fitness center attendance electronic records were associated with VO2max and self-report leisure-time physical activity. Therefore, results provide three evidence of construct validity of using fitness center attendance electronic records scores to assess leisure-time physical activity behavior.  相似文献

The current article provides an important insight into measurement differences between two commonly used self-reports and accelerometer-determined moderate to vigorous physical activity (MVPA) scores within matched samples across 1 school year. Participants were 998 fifth- through eighth-grade students who completed self-reports and 76 fifth- and sixth-grade children with accelerometers. The Health Behavior in School-aged Children (HBSC) Research Protocol showed the higher frequency of days exceeding 60 minutes of MVPA than the International Physical Activity Questionnaire Short Form (IPAQ-SF). Larger proportions of children achieved the MVPA guidelines based on HBSC results (girls 16%, boys 29%), than IPAQ-SF (girls 5%, boys 11%), or accelerometers data (girls 0%, boys 0%). MVPA remained stable over 12 months on the basis of both self-report and accelerometer results. Both self-report scales presented should be used with discretion in population studies, whereas accelerometer-determined data can be more authentic when personal guidance is required.  相似文献

以毛荣建(2003)所提出假设(在TPB理论基础上做出改进,将行为习惯、目标态度、情感体验3个变量融入了计划行为理论模型中,用来测量青少年体育锻炼态度。)为研究理论依托,进一步验证体育锻炼态度及其影响因素与体育锻炼行为之间的关系,通过《锻炼态度》与《体育锻炼行为》问卷对在校大学生分层随机调查,运用方差分析、相关分析、回归分析与路径分析等方法分析数据,结果表明:锻炼者与非锻炼者在体育锻炼态度各维度上呈现显著性差异;性别因素不能影响锻炼人群在体育锻炼态度的各项维度得分的差异性的结果,非锻炼人群也是如此;体育锻炼活动中,决定行为意向的关键变量因素是态度;具有高情感体验、或高认知的大学生,并不一定是锻炼者。路径分析说明,行为习惯、情感体验、行为认知、目标态度、主观标准一方面通过行为态度间接作用体育行为,另一方面,行为习惯、目标态度、主观标准对体育行为还具有直接的预测作用。  相似文献

Recent experiments on the ski simulator produced ambiguous results and raised unanswered questions concerning the true nature of “novice” behavior and the occurrence of behavioral changes during learning. The aim of the present experiment was to analyze the evolving behavior of three beginners during six practice sessions on a ski simulator. The position of the apparatus platform was recorded as time series and used for constructing dynamical models, including stiffness and damping functions. The results showed that novices tended to exploit a Rayleigh damping behavior during the first trials and then transition toward a van der Pol damping. These results replicate previous observations by Nourrit, Delignières, Caillou, Deschamps, and Lauriot (2003) and suggest the transition to the expert behavior could arise early in practice, when the task is of moderate difficulty. The discussion focuses on the properties of the observed learning dynamics and proposes a global conceptualization for acquiring complex motor skills.  相似文献

Abstract

The purpose of this study was to identify correlates of physical activity behavior in a sample of rural, predominantly African American youth. Three hundred sixty-one fifth-grade students from two rural counties in South Carolina (69% African American, median age = 11 years) completed a questionnaire designed to measure beliefs and social influences regarding physical activity, physical activity self-efficacy, perceived physical activity habits of family members and friends, and access to exercise and fitness equipment at home. After school physical activity and television watching were assessed using the Previous Day Physical Activity Recall (PDPAR). Students were classified as physically active according to a moderate physical activity standard: two or more 30-min blocks at an intensity of 3 METs (metabolic equivalents) or greater, and a vigorous physical activity standard: one or more 30-min blocks at an intensity of 6 METs or greater. According to the moderate physical activity standard, 34.9% of students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and exercise equipment at home to be significant correlates of low activity status. According to the vigorous physical activity standard, 32.1% of the students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and self-efficacy with respect to seeking support for physical activity to be significant correlates of low activity status. In summary, gender and the amount of television watching were found to be the most important correlates of physical activity in rural, predominantly African American youth.  相似文献

The primary objective of this research was to quantify the recommended minimum level (i.e., 50% of the class time) of moderate to vigorous physical activity within high school physical education via pedometry steps/min. A secondary objective was to explore the influence of lesson duration (i.e., traditional vs. block schedules) on quantifying moderate to vigorous physical activity via steps/min. Data (N = 218) were collected from 27 physical education classes taught by 10 certified physical educators in 6 schools. Physical activity measures were steps/min, percent of time engaged in moderate to vigorous physical activity (%MVPA), and time engaged in moderate to vigorous physical activity (MVPAtime, min.). Steps/min and %MVPA were strongly associated for all data and traditional and block schedules (r ≥ .94, p ≤ .01). Diagnostic statistics suggest that steps/min accurately discriminates between achievement and non-achievement of the 50% moderate to vigorous physical activity criterion. A steps/min interval of 82 to 83 was the most accurate indicator of the 50% criterion for all data. Steps/min and MVPAtime were strongly associated for traditional and block schedules independently (r ≥ .93, p ≤ .01) but not for all data combined (r ≥ .64, p ≤ .01). In conclusion, steps/min accurately quantifies the 50% moderate to vigorous physical activity criterion in high school physical education, and it is recommended as a physical education physical activity surveillance measure.  相似文献

大学生体育活动的态度及其行为的调查研究   总被引:19,自引:0,他引:19  
从认识论的角度看,大学生体育活动行为是受体育意识影响的,即参加什么样的体育活动,参加体育活动要达到什么样的目的,主要取决于他们对体育价值与功能的认识程度和所持的态度积极与否。因此,分析研究大学生体育活动的态度与行为,并作出解释和评价,不仅可以有针对性地提出建设性的对策,指导大学生的体育活动,同时也有助于高校体育教育改革的继续深化。1研究对象与方法1.1研究对象天津市8所普通高校的在校大学生,高校分别是天津大学、南开大学、天津医科大学、天津工业大学、天津师范大学、天津理工学院、天津商学院、天津外语学院。1.2研究方…  相似文献

体力活动测量方法研究进展   总被引:5,自引:0,他引:5  
体力活动水平与健康之间存在着剂量反应,如何准确测量体力活动水平是研究人员关心的问题。本文综述了体力活动研究的几种主要方法:行为观察法,双标水法,间接热量测量法,心率法,运动传感器法,问卷法。双标水法被认为是人体能量消耗测量的金标准,间接热量测量法也经常被用来校正其他测量方法,但这两种方法很难在大规模人群中应用。运动传感器和问卷法是在大规模人群中应用比较多的两种方法。  相似文献
